-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
-# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is '.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX

-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.

-  LT_SYS_LIBRARY_PATH
-              User-defined run-time library search path.
-  CPP         C preprocessor
-
-Use these variables to override the choices made by `configure' or to help

-# actually supported "in the wild" to an acceptable degree.
-# See automake bug#10828.
-# To make any issue more visible, cause the running configure to be aborted

-Oops!
-
-Your 'rm' program seems unable to run without file operands specified
-on the command line, even when the '-f' option is present.  This is contrary
-to the behaviour of most rm programs out there, and not conforming with
-the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
-
-Please tell bug-automake@gnu.org about your system, including the value
-of your $PATH and any error possibly output before this message.  This
-can help us improve future automake versions.

-.SH NAME
-lua \- Lua interpreter
-.SH SYNOPSIS
-.B lua
-[
-.I options
-]
-[
-.I script
-[
-.I args
-]
-]
-.SH DESCRIPTION
-.B lua
-is the standalone Lua interpreter.
-It loads and executes Lua programs,
-either in textual source form or
-in precompiled binary form.
-(Precompiled binaries are output by
-.BR luac ,
-the Lua compiler.)
-.B lua
-can be used as a batch interpreter and also interactively.
-.LP
-The given
-.I options
-are handled in order and then
-the Lua program in file
-.I script
-is loaded and executed.
-The given
-.I args
-are available to
-.I script
-as strings in a global table named
-.BR arg .
-If no options or arguments are given,
-then
-.B "\-v \-i"
-is assumed when the standard input is a terminal;
-otherwise,
-.B "\-"
-is assumed.
-.LP
-In interactive mode,
-.B lua
-prompts the user,
-reads lines from the standard input,
-and executes them as they are read.
-If a line does not contain a complete statement,
-then a secondary prompt is displayed and
-lines are read until a complete statement is formed or
-a syntax error is found.
-If a line starts with
-.BR '=' ,
-then
-.B lua
-evaluates and displays
-the values of the expressions in the remainder of the line.
-.LP
-At the very start,
-before even handling the command line,
-.B lua
-checks the contents of the environment variables
-.B LUA_INIT_5_2
-or
-.BR LUA_INIT ,
-in that order.
-If the contents is of the form
-.RI '@ filename ',
-then
-.I filename
-is executed.
-Otherwise, the string is assumed to be a Lua statement and is executed.
-.SH OPTIONS
-.TP
-.BI \-e " stat"
-execute statement
-.IR stat .
-.TP
-.B \-i
-enter interactive mode after executing
-.IR script .
-.TP
-.BI \-l " name"

-.SH NAME
-luac \- Lua compiler
-.SH SYNOPSIS
-.B luac
-[
-.I options
-] [
-.I filenames
-]
-.SH DESCRIPTION
-.B luac
-is the Lua compiler.
-It translates programs written in the Lua programming language
-into binary files containing precompiled chunks
-that can be later loaded and executed.
-.LP
-The main advantages of precompiling chunks are:
-faster loading,
-protecting source code from accidental user changes,
-and
-off-line syntax checking.
-Precompiling does not imply faster execution
-because in Lua chunks are always compiled into bytecodes before being executed.
-.B luac
-simply allows those bytecodes to be saved in a file for later execution.
-Precompiled chunks are not necessarily smaller than the corresponding source.
-The main goal in precompiling is faster loading.
-.LP
-In the command line,
-you can mix
-text files containing Lua source and
-binary files containing precompiled chunks.
-.B luac
-produces a single output file containing the combined bytecodes
-for all files given.
-Executing the combined file is equivalent to executing the given files.
-By default,
-the output file is named
-.BR luac.out ,
-but you can change this with the
-.B \-o
-option.
-.LP
-Precompiled chunks are
-.I not
-portable across different architectures.
-Moreover,
-the internal format of precompiled chunks
-is likely to change when a new version of Lua is released.
-Make sure you save the source files of all Lua programs that you precompile.
-.LP
-.SH OPTIONS
-.TP
-.B \-l
-produce a listing of the compiled bytecode for Lua's virtual machine.
-Listing bytecodes is useful to learn about Lua's virtual machine.
-If no files are given, then
-.B luac
-loads
-.B luac.out
-and lists its contents.
-Use
-.B \-l \-l
-for a full listing.
-.TP
-.BI \-o " file"
-output to
-.IR file ,
-instead of the default
-.BR luac.out .
-(You can use
-.B "'\-'"
-for standard output,
-but not on platforms that open standard output in text mode.)
-The output file may be one of the given files because
-all files are loaded before the output file is written.
-Be careful not to overwrite precious files.
-.TP
-.B \-p
-load files but do not generate any output file.
-Used mainly for syntax checking and for testing precompiled chunks:
-corrupted files will probably generate errors when loaded.
-If no files are given, then
-.B luac
-loads
-.B luac.out
-and tests its contents.
-No messages are displayed if the file loads without errors.
-.TP
-.B \-s
-strip debug information before writing the output file.
-This saves some space in very large chunks,
-but if errors occur when running a stripped chunk,
-then the error messages may not contain the full information they usually do.
-In particular,
-line numbers and names of local variables are lost.
-.TP
-.B \-v
-show version information.
-.TP
-.B \-\-
-stop handling options.
-.TP
-.B \-
-stop handling options and process standard input.

-<h1>1 &ndash; <a name="1">Introduction</a></h1>
-
-<p>
-Lua is an extension programming language designed to support
-general procedural programming with data description
-facilities.
-It also offers good support for object-oriented programming,
-functional programming, and data-driven programming.
-Lua is intended to be used as a powerful, lightweight,
-embeddable scripting language for any program that needs one.
-Lua is implemented as a library, written in <em>clean C</em>,
-the common subset of Standard&nbsp;C and C++.
-
-
-<p>
-Being an extension language, Lua has no notion of a "main" program:
-it only works <em>embedded</em> in a host client,
-called the <em>embedding program</em> or simply the <em>host</em>.
-The host program can invoke functions to execute a piece of Lua code,
-can write and read Lua variables,
-and can register C&nbsp;functions to be called by Lua code.
-Through the use of C&nbsp;functions, Lua can be augmented to cope with
-a wide range of different domains,
-thus creating customized programming languages sharing a syntactical framework.
-The Lua distribution includes a sample host program called <code>lua</code>,
-which uses the Lua library to offer a complete, standalone Lua interpreter,
-for interactive or batch use.
-
-
-<p>
-Lua is free software,
-and is provided as usual with no guarantees,
-as stated in its license.
-The implementation described in this manual is available
-at Lua's official web site, <code>www.lua.org</code>.
-
-
-<p>
-Like any other reference manual,
-this document is dry in places.
-For a discussion of the decisions behind the design of Lua,
-see the technical papers available at Lua's web site.
-For a detailed introduction to programming in Lua,
-see Roberto's book, <em>Programming in Lua</em>.
-
-
-
-<h1>2 &ndash; <a name="2">Basic Concepts</a></h1>
-
-<p>
-This section describes the basic concepts of the language.
-
-
-
-<h2>2.1 &ndash; <a name="2.1">Values and Types</a></h2>
-
-<p>
-Lua is a <em>dynamically typed language</em>.
-This means that
-variables do not have types; only values do.
-There are no type definitions in the language.
-All values carry their own type.
-
-
-<p>
-All values in Lua are <em>first-class values</em>.
-This means that all values can be stored in variables,
-passed as arguments to other functions, and returned as results.
-
-
-<p>
-There are eight basic types in Lua:
-<em>nil</em>, <em>boolean</em>, <em>number</em>,
-<em>string</em>, <em>function</em>, <em>userdata</em>,
-<em>thread</em>, and <em>table</em>.
-<em>Nil</em> is the type of the value <b>nil</b>,
-whose main property is to be different from any other value;
-it usually represents the absence of a useful value.
-<em>Boolean</em> is the type of the values <b>false</b> and <b>true</b>.
-Both <b>nil</b> and <b>false</b> make a condition false;
-any other value makes it true.
-<em>Number</em> represents real (double-precision floating-point) numbers.
-Operations on numbers follow the same rules of
-the underlying C&nbsp;implementation,
-which, in turn, usually follows the IEEE 754 standard.
-(It is easy to build Lua interpreters that use other
-internal representations for numbers,
-such as single-precision floats or long integers;
-see file <code>luaconf.h</code>.)
-<em>String</em> represents immutable sequences of bytes.
-
-Lua is 8-bit clean:
-strings can contain any 8-bit value,
-including embedded zeros ('<code>\0</code>').
-
-
-<p>
-Lua can call (and manipulate) functions written in Lua and
-functions written in C
-(see <a href="#3.4.9">&sect;3.4.9</a>).
-
-
-<p>
-The type <em>userdata</em> is provided to allow arbitrary C&nbsp;data to
-be stored in Lua variables.
-A userdata value is a pointer to a block of raw memory.
-There are two kinds of userdata:
-full userdata, where the block of memory is managed by Lua,
-and light userdata, where the block of memory is managed by the host.
-Userdata has no predefined operations in Lua,
-except assignment and identity test.
-By using <em>metatables</em>,
-the programmer can define operations for full userdata values
-(see <a href="#2.4">&sect;2.4</a>).
-Userdata values cannot be created or modified in Lua,
-only through the C&nbsp;API.
-This guarantees the integrity of data owned by the host program.
-
-
-<p>
-The type <em>thread</em> represents independent threads of execution
-and it is used to implement coroutines (see <a href="#2.6">&sect;2.6</a>).
-Do not confuse Lua threads with operating-system threads.
-Lua supports coroutines on all systems,
-even those that do not support threads.
-
-
-<p>
-The type <em>table</em> implements associative arrays,
-that is, arrays that can be indexed not only with numbers,
-but with any Lua value except <b>nil</b> and NaN
-(<em>Not a Number</em>, a special numeric value used to represent
-undefined or unrepresentable results, such as <code>0/0</code>).
-Tables can be <em>heterogeneous</em>;
-that is, they can contain values of all types (except <b>nil</b>).
-Any key with value <b>nil</b> is not considered part of the table.
-Conversely, any key that is not part of a table has
-an associated value <b>nil</b>.
-
-
-<p>
-Tables are the sole data structuring mechanism in Lua;
-they can be used to represent ordinary arrays, sequences,
-symbol tables, sets, records, graphs, trees, etc.
-To represent records, Lua uses the field name as an index.
-The language supports this representation by
-providing <code>a.name</code> as syntactic sugar for <code>a["name"]</code>.
-There are several convenient ways to create tables in Lua
-(see <a href="#3.4.8">&sect;3.4.8</a>).
-
-
-<p>
-We use the term <em>sequence</em> to denote a table where
-the set of all positive numeric keys is equal to <em>{1..n}</em>
-for some integer <em>n</em>,
-which is called the length of the sequence (see <a href="#3.4.6">&sect;3.4.6</a>).
-
-
-<p>
-Like indices,
-the values of table fields can be of any type.
-In particular,
-because functions are first-class values,
-table fields can contain functions.
-Thus tables can also carry <em>methods</em> (see <a href="#3.4.10">&sect;3.4.10</a>).
-
-
-<p>
-The indexing of tables follows
-the definition of raw equality in the language.
-The expressions <code>a[i]</code> and <code>a[j]</code>
-denote the same table element
-if and only if <code>i</code> and <code>j</code> are raw equal
-(that is, equal without metamethods).
-
-
-<p>
-Tables, functions, threads, and (full) userdata values are <em>objects</em>:
-variables do not actually <em>contain</em> these values,
-only <em>references</em> to them.
-Assignment, parameter passing, and function returns
-always manipulate references to such values;
-these operations do not imply any kind of copy.
-
-
-<p>
-The library function <a href="#pdf-type"><code>type</code></a> returns a string describing the type
-of a given value (see <a href="#6.1">&sect;6.1</a>).
-
-
-
-
-
-<h2>2.2 &ndash; <a name="2.2">Environments and the Global Environment</a></h2>
-
-<p>
-As will be discussed in <a href="#3.2">&sect;3.2</a> and <a href="#3.3.3">&sect;3.3.3</a>,
-any reference to a global name <code>var</code> is syntactically translated
-to <code>_ENV.var</code>.
-Moreover, every chunk is compiled in the scope of
-an external local variable called <code>_ENV</code> (see <a href="#3.3.2">&sect;3.3.2</a>),
-so <code>_ENV</code> itself is never a global name in a chunk.
-
-
-<p>
-Despite the existence of this external <code>_ENV</code> variable and
-the translation of global names,
-<code>_ENV</code> is a completely regular name.
-In particular,
-you can define new variables and parameters with that name.
-Each reference to a global name uses the <code>_ENV</code> that is
-visible at that point in the program,
-following the usual visibility rules of Lua (see <a href="#3.5">&sect;3.5</a>).
-
-
-<p>
-Any table used as the value of <code>_ENV</code> is called an <em>environment</em>.
-
-
-<p>
-Lua keeps a distinguished environment called the <em>global environment</em>.
-This value is kept at a special index in the C registry (see <a href="#4.5">&sect;4.5</a>).
-In Lua, the variable <a href="#pdf-_G"><code>_G</code></a> is initialized with this same value.
-
-
-<p>
-When Lua compiles a chunk,
-it initializes the value of its <code>_ENV</code> upvalue
-with the global environment (see <a href="#pdf-load"><code>load</code></a>).
-Therefore, by default,
-global variables in Lua code refer to entries in the global environment.
-Moreover, all standard libraries are loaded in the global environment
-and several functions there operate on that environment.
-You can use <a href="#pdf-load"><code>load</code></a> (or <a href="#pdf-loadfile"><code>loadfile</code></a>)
-to load a chunk with a different environment.
-(In C, you have to load the chunk and then change the value
-of its first upvalue.)
-
-
-<p>
-If you change the global environment in the registry
-(through C code or the debug library),
-all chunks loaded after the change will get the new environment.
-Previously loaded chunks are not affected, however,
-as each has its own reference to the environment in its <code>_ENV</code> variable.
-Moreover, the variable <a href="#pdf-_G"><code>_G</code></a>
-(which is stored in the original global environment)
-is never updated by Lua.

-<h2>2.3 &ndash; <a name="2.3">Error Handling</a></h2>
-
-<p>
-Because Lua is an embedded extension language,
-all Lua actions start from C&nbsp;code in the host program
-calling a function from the Lua library (see <a href="#lua_pcall"><code>lua_pcall</code></a>).
-Whenever an error occurs during
-the compilation or execution of a Lua chunk,
-control returns to the host,
-which can take appropriate measures
-(such as printing an error message).
-
-
-<p>
-Lua code can explicitly generate an error by calling the
-<a href="#pdf-error"><code>error</code></a> function.
-If you need to catch errors in Lua,
-you can use <a href="#pdf-pcall"><code>pcall</code></a> or <a href="#pdf-xpcall"><code>xpcall</code></a>
-to call a given function in <em>protected mode</em>.
-
-
-<p>
-Whenever there is an error,
-an <em>error object</em> (also called an <em>error message</em>)
-is propagated with information about the error.
-Lua itself only generates errors where the error object is a string,
-but programs may generate errors with
-any value for the error object.
-
-
-<p>
-When you use <a href="#pdf-xpcall"><code>xpcall</code></a> or <a href="#lua_pcall"><code>lua_pcall</code></a>,
-you may give a <em>message handler</em>
-to be called in case of errors.
-This function is called with the original error message
-and returns a new error message.
-It is called before the error unwinds the stack,
-so that it can gather more information about the error,
-for instance by inspecting the stack and creating a stack traceback.
-This message handler is still protected by the protected call;
-so, an error inside the message handler
-will call the message handler again.
-If this loop goes on, Lua breaks it and returns an appropriate message.
-
-
-
-
-
-<h2>2.4 &ndash; <a name="2.4">Metatables and Metamethods</a></h2>
-
-<p>
-Every value in Lua can have a <em>metatable</em>.
-This <em>metatable</em> is an ordinary Lua table
-that defines the behavior of the original value
-under certain special operations.
-You can change several aspects of the behavior
-of operations over a value by setting specific fields in its metatable.
-For instance, when a non-numeric value is the operand of an addition,
-Lua checks for a function in the field "<code>__add</code>" of the value's metatable.
-If it finds one,
-Lua calls this function to perform the addition.
-
-
-<p>
-The keys in a metatable are derived from the <em>event</em> names;
-the corresponding values are called <em>metamethods</em>.
-In the previous example, the event is <code>"add"</code>
-and the metamethod is the function that performs the addition.
-
-
-<p>
-You can query the metatable of any value
-using the <a href="#pdf-getmetatable"><code>getmetatable</code></a> function.
-
-
-<p>
-You can replace the metatable of tables
-using the <a href="#pdf-setmetatable"><code>setmetatable</code></a> function.
-You cannot change the metatable of other types from Lua
-(except by using the debug library);
-you must use the C&nbsp;API for that.
-
-
-<p>
-Tables and full userdata have individual metatables
-(although multiple tables and userdata can share their metatables).
-Values of all other types share one single metatable per type;
-that is, there is one single metatable for all numbers,
-one for all strings, etc.
-By default, a value has no metatable,
-but the string library sets a metatable for the string type (see <a href="#6.4">&sect;6.4</a>).
-
-
-<p>
-A metatable controls how an object behaves in arithmetic operations,
-order comparisons, concatenation, length operation, and indexing.
-A metatable also can define a function to be called
-when a userdata or a table is garbage collected.
-When Lua performs one of these operations over a value,
-it checks whether this value has a metatable with the corresponding event.
-If so, the value associated with that key (the metamethod)
-controls how Lua will perform the operation.
-
-
-<p>
-Metatables control the operations listed next.
-Each operation is identified by its corresponding name.
-The key for each operation is a string with its name prefixed by
-two underscores, '<code>__</code>';
-for instance, the key for operation "add" is the
-string "<code>__add</code>".
-
-
-<p>
-The semantics of these operations is better explained by a Lua function
-describing how the interpreter executes the operation.
-The code shown here in Lua is only illustrative;
-the real behavior is hard coded in the interpreter
-and it is much more efficient than this simulation.
-All functions used in these descriptions
-(<a href="#pdf-rawget"><code>rawget</code></a>, <a href="#pdf-tonumber"><code>tonumber</code></a>, etc.)
-are described in <a href="#6.1">&sect;6.1</a>.
-In particular, to retrieve the metamethod of a given object,
-we use the expression
-
-<pre>
-     metatable(obj)[event]
-</pre><p>
-This should be read as
-
-<pre>
-     rawget(getmetatable(obj) or {}, event)
-</pre><p>
-This means that the access to a metamethod does not invoke other metamethods,
-and access to objects with no metatables does not fail
-(it simply results in <b>nil</b>).
-
-
-<p>
-For the unary <code>-</code> and <code>#</code> operators,
-the metamethod is called with a dummy second argument.
-This extra argument is only to simplify Lua's internals;
-it may be removed in future versions and therefore it is not present
-in the following code.
-(For most uses this extra argument is irrelevant.)

-<h2>2.5 &ndash; <a name="2.5">Garbage Collection</a></h2>
-
-<p>
-Lua performs automatic memory management.
-This means that
-you have to worry neither about allocating memory for new objects
-nor about freeing it when the objects are no longer needed.
-Lua manages memory automatically by running
-a <em>garbage collector</em> to collect all <em>dead objects</em>
-(that is, objects that are no longer accessible from Lua).
-All memory used by Lua is subject to automatic management:
-strings, tables, userdata, functions, threads, internal structures, etc.
-
-
-<p>
-Lua implements an incremental mark-and-sweep collector.
-It uses two numbers to control its garbage-collection cycles:
-the <em>garbage-collector pause</em> and
-the <em>garbage-collector step multiplier</em>.
-Both use percentage points as units
-(e.g., a value of 100 means an internal value of 1).
-
-
-<p>
-The garbage-collector pause
-controls how long the collector waits before starting a new cycle.
-Larger values make the collector less aggressive.
-Values smaller than 100 mean the collector will not wait to
-start a new cycle.
-A value of 200 means that the collector waits for the total memory in use
-to double before starting a new cycle.
-
-
-<p>
-The garbage-collector step multiplier
-controls the relative speed of the collector relative to
-memory allocation.
-Larger values make the collector more aggressive but also increase
-the size of each incremental step.
-Values smaller than 100 make the collector too slow and
-can result in the collector never finishing a cycle.
-The default is 200,
-which means that the collector runs at "twice"
-the speed of memory allocation.
-
-
-<p>
-If you set the step multiplier to a very large number
-(larger than 10% of the maximum number of
-bytes that the program may use),
-the collector behaves like a stop-the-world collector.
-If you then set the pause to 200,
-the collector behaves as in old Lua versions,
-doing a complete collection every time Lua doubles its
-memory usage.
-
-
-<p>
-You can change these numbers by calling <a href="#lua_gc"><code>lua_gc</code></a> in C
-or <a href="#pdf-collectgarbage"><code>collectgarbage</code></a> in Lua.
-You can also use these functions to control
-the collector directly (e.g., stop and restart it).
-
-
-<p>
-As an experimental feature in Lua 5.2,
-you can change the collector's operation mode
-from incremental to <em>generational</em>.
-A <em>generational collector</em> assumes that most objects die young,
-and therefore it traverses only young (recently created) objects.
-This behavior can reduce the time used by the collector,
-but also increases memory usage (as old dead objects may accumulate).
-To mitigate this second problem,
-from time to time the generational collector performs a full collection.
-Remember that this is an experimental feature;
-you are welcome to try it,
-but check your gains.
-
-
-
-<h3>2.5.1 &ndash; <a name="2.5.1">Garbage-Collection Metamethods</a></h3>
-
-<p>
-You can set garbage-collector metamethods for tables
-and, using the C&nbsp;API,
-for full userdata (see <a href="#2.4">&sect;2.4</a>).
-These metamethods are also called <em>finalizers</em>.
-Finalizers allow you to coordinate Lua's garbage collection
-with external resource management
-(such as closing files, network or database connections,
-or freeing your own memory).
-
-
-<p>
-For an object (table or userdata) to be finalized when collected,
-you must <em>mark</em> it for finalization.
-
-You mark an object for finalization when you set its metatable
-and the metatable has a field indexed by the string "<code>__gc</code>".
-Note that if you set a metatable without a <code>__gc</code> field
-and later create that field in the metatable,
-the object will not be marked for finalization.
-However, after an object is marked,
-you can freely change the <code>__gc</code> field of its metatable.
-
-
-<p>
-When a marked object becomes garbage,
-it is not collected immediately by the garbage collector.
-Instead, Lua puts it in a list.
-After the collection,
-Lua does the equivalent of the following function
-for each object in that list:
-
-<pre>
-     function gc_event (obj)
-       local h = metatable(obj).__gc
-       if type(h) == "function" then
-         h(obj)
-       end
-     end
-</pre>
-
-<p>
-At the end of each garbage-collection cycle,
-the finalizers for objects are called in
-the reverse order that they were marked for collection,
-among those collected in that cycle;
-that is, the first finalizer to be called is the one associated
-with the object marked last in the program.
-The execution of each finalizer may occur at any point during
-the execution of the regular code.
-
-
-<p>
-Because the object being collected must still be used by the finalizer,
-it (and other objects accessible only through it)
-must be <em>resurrected</em> by Lua.
-Usually, this resurrection is transient,
-and the object memory is freed in the next garbage-collection cycle.
-However, if the finalizer stores the object in some global place
-(e.g., a global variable),
-then there is a permanent resurrection.
-In any case,
-the object memory is freed only when it becomes completely inaccessible;
-its finalizer will never be called twice.
-
-
-<p>
-When you close a state (see <a href="#lua_close"><code>lua_close</code></a>),
-Lua calls the finalizers of all objects marked for finalization,
-following the reverse order that they were marked.
-If any finalizer marks new objects for collection during that phase,
-these new objects will not be finalized.
-
-
-
-
-
-<h3>2.5.2 &ndash; <a name="2.5.2">Weak Tables</a></h3>
-
-<p>
-A <em>weak table</em> is a table whose elements are
-<em>weak references</em>.
-A weak reference is ignored by the garbage collector.
-In other words,
-if the only references to an object are weak references,
-then the garbage collector will collect that object.
-
-
-<p>
-A weak table can have weak keys, weak values, or both.
-A table with weak keys allows the collection of its keys,
-but prevents the collection of its values.
-A table with both weak keys and weak values allows the collection of
-both keys and values.
-In any case, if either the key or the value is collected,
-the whole pair is removed from the table.
-The weakness of a table is controlled by the
-<code>__mode</code> field of its metatable.
-If the <code>__mode</code> field is a string containing the character&nbsp;'<code>k</code>',
-the keys in the table are weak.
-If <code>__mode</code> contains '<code>v</code>',
-the values in the table are weak.
-
-
-<p>
-A table with weak keys and strong values
-is also called an <em>ephemeron table</em>.
-In an ephemeron table,
-a value is considered reachable only if its key is reachable.
-In particular,
-if the only reference to a key comes through its value,
-the pair is removed.
-
-
-<p>
-Any change in the weakness of a table may take effect only
-at the next collect cycle.
-In particular, if you change the weakness to a stronger mode,
-Lua may still collect some items from that table
-before the change takes effect.
-
-
-<p>
-Only objects that have an explicit construction
-are removed from weak tables.
-Values, such as numbers and light C functions,
-are not subject to garbage collection,
-and therefore are not removed from weak tables
-(unless its associated value is collected).
-Although strings are subject to garbage collection,
-they do not have an explicit construction,
-and therefore are not removed from weak tables.
-
-
-<p>
-Resurrected objects
-(that is, objects being finalized
-and objects accessible only through objects being finalized)
-have a special behavior in weak tables.
-They are removed from weak values before running their finalizers,
-but are removed from weak keys only in the next collection
-after running their finalizers, when such objects are actually freed.
-This behavior allows the finalizer to access properties
-associated with the object through weak tables.
-
-
-<p>
-If a weak table is among the resurrected objects in a collection cycle,
-it may not be properly cleared until the next cycle.

-<h2>2.6 &ndash; <a name="2.6">Coroutines</a></h2>
-
-<p>
-Lua supports coroutines,
-also called <em>collaborative multithreading</em>.
-A coroutine in Lua represents an independent thread of execution.
-Unlike threads in multithread systems, however,
-a coroutine only suspends its execution by explicitly calling
-a yield function.
-
-
-<p>
-You create a coroutine by calling <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>.
-Its sole argument is a function
-that is the main function of the coroutine.
-The <code>create</code> function only creates a new coroutine and
-returns a handle to it (an object of type <em>thread</em>);
-it does not start the coroutine.
-
-
-<p>
-You execute a coroutine by calling <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>.
-When you first call <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>,
-passing as its first argument
-a thread returned by <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>,
-the coroutine starts its execution,
-at the first line of its main function.
-Extra arguments passed to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> are passed on
-to the coroutine main function.
-After the coroutine starts running,
-it runs until it terminates or <em>yields</em>.
-
-
-<p>
-A coroutine can terminate its execution in two ways:
-normally, when its main function returns
-(explicitly or implicitly, after the last instruction);
-and abnormally, if there is an unprotected error.
-In the first case, <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns <b>true</b>,
-plus any values returned by the coroutine main function.
-In case of errors, <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns <b>false</b>
-plus an error message.
-
-
-<p>
-A coroutine yields by calling <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a>.
-When a coroutine yields,
-the corresponding <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns immediately,
-even if the yield happens inside nested function calls
-(that is, not in the main function,
-but in a function directly or indirectly called by the main function).
-In the case of a yield, <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> also returns <b>true</b>,
-plus any values passed to <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a>.
-The next time you resume the same coroutine,
-it continues its execution from the point where it yielded,
-with the call to <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a> returning any extra
-arguments passed to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>.
-
-
-<p>
-Like <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>,
-the <a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a> function also creates a coroutine,
-but instead of returning the coroutine itself,
-it returns a function that, when called, resumes the coroutine.
-Any arguments passed to this function
-go as extra arguments to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>.
-<a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a> returns all the values returned by <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>,
-except the first one (the boolean error code).
-Unlike <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>,
-<a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a> does not catch errors;
-any error is propagated to the caller.
-
-
-<p>
-As an example of how coroutines work,
-consider the following code:
-
-<pre>
-     function foo (a)
-       print("foo", a)
-       return coroutine.yield(2*a)
-     end
-     
-     co = coroutine.create(function (a,b)
-           print("co-body", a, b)
-           local r = foo(a+1)
-           print("co-body", r)
-           local r, s = coroutine.yield(a+b, a-b)
-           print("co-body", r, s)
-           return b, "end"
-     end)
-     
-     print("main", coroutine.resume(co, 1, 10))
-     print("main", coroutine.resume(co, "r"))
-     print("main", coroutine.resume(co, "x", "y"))
-     print("main", coroutine.resume(co, "x", "y"))
-</pre><p>
-When you run it, it produces the following output:
-
-<pre>
-     co-body 1       10
-     foo     2
-     main    true    4
-     co-body r
-     main    true    11      -9
-     co-body x       y
-     main    true    10      end
-     main    false   cannot resume dead coroutine
-</pre>
-
-<p>
-You can also create and manipulate coroutines through the C API:
-see functions <a href="#lua_newthread"><code>lua_newthread</code></a>, <a href="#lua_resume"><code>lua_resume</code></a>,
-and <a href="#lua_yield"><code>lua_yield</code></a>.

-<h1>3 &ndash; <a name="3">The Language</a></h1>
-
-<p>
-This section describes the lexis, the syntax, and the semantics of Lua.
-In other words,
-this section describes
-which tokens are valid,
-how they can be combined,
-and what their combinations mean.
-
-
-<p>
-Language constructs will be explained using the usual extended BNF notation,
-in which
-{<em>a</em>}&nbsp;means&nbsp;0 or more <em>a</em>'s, and
-[<em>a</em>]&nbsp;means an optional <em>a</em>.
-Non-terminals are shown like non-terminal,
-keywords are shown like <b>kword</b>,
-and other terminal symbols are shown like &lsquo;<b>=</b>&rsquo;.
-The complete syntax of Lua can be found in <a href="#9">&sect;9</a>
-at the end of this manual.
-
-
-
-<h2>3.1 &ndash; <a name="3.1">Lexical Conventions</a></h2>
-
-<p>
-Lua is a free-form language.
-It ignores spaces (including new lines) and comments
-between lexical elements (tokens),
-except as delimiters between names and keywords.
-
-
-<p>
-<em>Names</em>
-(also called <em>identifiers</em>)
-in Lua can be any string of letters,
-digits, and underscores,
-not beginning with a digit.
-Identifiers are used to name variables, table fields, and labels.
-
-
-<p>
-The following <em>keywords</em> are reserved
-and cannot be used as names:
-
-
-<pre>
-     and       break     do        else      elseif    end
-     false     for       function  goto      if        in
-     local     nil       not       or        repeat    return
-     then      true      until     while
-</pre>
-
-<p>
-Lua is a case-sensitive language:
-<code>and</code> is a reserved word, but <code>And</code> and <code>AND</code>
-are two different, valid names.
-As a convention, names starting with an underscore followed by
-uppercase letters (such as <a href="#pdf-_VERSION"><code>_VERSION</code></a>)
-are reserved for variables used by Lua.
-
-
-<p>
-The following strings denote other tokens:
-
-<pre>
-     +     -     *     /     %     ^     #
-     ==    ~=    &lt;=    &gt;=    &lt;     &gt;     =
-     (     )     {     }     [     ]     ::
-     ;     :     ,     .     ..    ...
-</pre>
-
-<p>
-<em>Literal strings</em>
-can be delimited by matching single or double quotes,
-and can contain the following C-like escape sequences:
-'<code>\a</code>' (bell),
-'<code>\b</code>' (backspace),
-'<code>\f</code>' (form feed),
-'<code>\n</code>' (newline),
-'<code>\r</code>' (carriage return),
-'<code>\t</code>' (horizontal tab),
-'<code>\v</code>' (vertical tab),
-'<code>\\</code>' (backslash),
-'<code>\"</code>' (quotation mark [double quote]),
-and '<code>\'</code>' (apostrophe [single quote]).
-A backslash followed by a real newline
-results in a newline in the string.
-The escape sequence '<code>\z</code>' skips the following span
-of white-space characters,
-including line breaks;
-it is particularly useful to break and indent a long literal string
-into multiple lines without adding the newlines and spaces
-into the string contents.
-
-
-<p>
-A byte in a literal string can also be specified by its numerical value.
-This can be done with the escape sequence <code>\x<em>XX</em></code>,
-where <em>XX</em> is a sequence of exactly two hexadecimal digits,
-or with the escape sequence <code>\<em>ddd</em></code>,
-where <em>ddd</em> is a sequence of up to three decimal digits.
-(Note that if a decimal escape is to be followed by a digit,
-it must be expressed using exactly three digits.)
-Strings in Lua can contain any 8-bit value, including embedded zeros,
-which can be specified as '<code>\0</code>'.
-
-
-<p>
-Literal strings can also be defined using a long format
-enclosed by <em>long brackets</em>.
-We define an <em>opening long bracket of level <em>n</em></em> as an opening
-square bracket followed by <em>n</em> equal signs followed by another
-opening square bracket.
-So, an opening long bracket of level&nbsp;0 is written as <code>[[</code>,
-an opening long bracket of level&nbsp;1 is written as <code>[=[</code>,
-and so on.
-A <em>closing long bracket</em> is defined similarly;
-for instance, a closing long bracket of level&nbsp;4 is written as <code>]====]</code>.
-A <em>long literal</em> starts with an opening long bracket of any level and
-ends at the first closing long bracket of the same level.
-It can contain any text except a closing bracket of the proper level.
-Literals in this bracketed form can run for several lines,
-do not interpret any escape sequences,
-and ignore long brackets of any other level.
-Any kind of end-of-line sequence
-(carriage return, newline, carriage return followed by newline,
-or newline followed by carriage return)
-is converted to a simple newline.
-
-
-<p>
-Any byte in a literal string not
-explicitly affected by the previous rules represents itself.
-However, Lua opens files for parsing in text mode,
-and the system file functions may have problems with
-some control characters.
-So, it is safer to represent
-non-text data as a quoted literal with
-explicit escape sequences for non-text characters.
-
-
-<p>
-For convenience,
-when the opening long bracket is immediately followed by a newline,
-the newline is not included in the string.
-As an example, in a system using ASCII
-(in which '<code>a</code>' is coded as&nbsp;97,
-newline is coded as&nbsp;10, and '<code>1</code>' is coded as&nbsp;49),
-the five literal strings below denote the same string:
-
-<pre>
-     a = 'alo\n123"'
-     a = "alo\n123\""
-     a = '\97lo\10\04923"'
-     a = [[alo
-     123"]]
-     a = [==[
-     alo
-     123"]==]
-</pre>
-
-<p>
-A <em>numerical constant</em> can be written with an optional fractional part
-and an optional decimal exponent,
-marked by a letter '<code>e</code>' or '<code>E</code>'.
-Lua also accepts hexadecimal constants,
-which start with <code>0x</code> or <code>0X</code>.
-Hexadecimal constants also accept an optional fractional part
-plus an optional binary exponent,
-marked by a letter '<code>p</code>' or '<code>P</code>'.
-Examples of valid numerical constants are
-
-<pre>
-     3     3.0     3.1416     314.16e-2     0.31416E1
-     0xff  0x0.1E  0xA23p-4   0X1.921FB54442D18P+1
-</pre>
-
-<p>
-A <em>comment</em> starts with a double hyphen (<code>--</code>)
-anywhere outside a string.
-If the text immediately after <code>--</code> is not an opening long bracket,
-the comment is a <em>short comment</em>,
-which runs until the end of the line.
-Otherwise, it is a <em>long comment</em>,
-which runs until the corresponding closing long bracket.
-Long comments are frequently used to disable code temporarily.
-
-
-
-
-
-<h2>3.2 &ndash; <a name="3.2">Variables</a></h2>
-
-<p>
-Variables are places that store values.
-There are three kinds of variables in Lua:
-global variables, local variables, and table fields.
-
-
-<p>
-A single name can denote a global variable or a local variable
-(or a function's formal parameter,
-which is a particular kind of local variable):
-
-<pre>
-	var ::= Name
-</pre><p>
-Name denotes identifiers, as defined in <a href="#3.1">&sect;3.1</a>.
-
-
-<p>
-Any variable name is assumed to be global unless explicitly declared
-as a local (see <a href="#3.3.7">&sect;3.3.7</a>).
-Local variables are <em>lexically scoped</em>:
-local variables can be freely accessed by functions
-defined inside their scope (see <a href="#3.5">&sect;3.5</a>).
-
-
-<p>
-Before the first assignment to a variable, its value is <b>nil</b>.
-
-
-<p>
-Square brackets are used to index a table:
-
-<pre>
-	var ::= prefixexp &lsquo;<b>[</b>&rsquo; exp &lsquo;<b>]</b>&rsquo;
-</pre><p>
-The meaning of accesses to table fields can be changed via metatables.
-An access to an indexed variable <code>t[i]</code> is equivalent to
-a call <code>gettable_event(t,i)</code>.
-(See <a href="#2.4">&sect;2.4</a> for a complete description of the
-<code>gettable_event</code> function.
-This function is not defined or callable in Lua.
-We use it here only for explanatory purposes.)
-
-
-<p>
-The syntax <code>var.Name</code> is just syntactic sugar for
-<code>var["Name"]</code>:
-
-<pre>
-	var ::= prefixexp &lsquo;<b>.</b>&rsquo; Name
-</pre>
-
-<p>
-An access to a global variable <code>x</code>
-is equivalent to <code>_ENV.x</code>.
-Due to the way that chunks are compiled,
-<code>_ENV</code> is never a global name (see <a href="#2.2">&sect;2.2</a>).
-
-
-
-
-
-<h2>3.3 &ndash; <a name="3.3">Statements</a></h2>
-
-<p>
-Lua supports an almost conventional set of statements,
-similar to those in Pascal or C.
-This set includes
-assignments, control structures, function calls,
-and variable declarations.
-
-
-
-<h3>3.3.1 &ndash; <a name="3.3.1">Blocks</a></h3>
-
-<p>
-A block is a list of statements,
-which are executed sequentially:
-
-<pre>
-	block ::= {stat}
-</pre><p>
-Lua has <em>empty statements</em>
-that allow you to separate statements with semicolons,
-start a block with a semicolon
-or write two semicolons in sequence:
-
-<pre>
-	stat ::= &lsquo;<b>;</b>&rsquo;
-</pre>
-
-<p>
-Function calls and assignments
-can start with an open parenthesis.
-This possibility leads to an ambiguity in Lua's grammar.
-Consider the following fragment:
-
-<pre>
-     a = b + c
-     (print or io.write)('done')
-</pre><p>
-The grammar could see it in two ways:
-
-<pre>
-     a = b + c(print or io.write)('done')
-     
-     a = b + c; (print or io.write)('done')
-</pre><p>
-The current parser always sees such constructions
-in the first way,
-interpreting the open parenthesis
-as the start of the arguments to a call.
-To avoid this ambiguity,
-it is a good practice to always precede with a semicolon
-statements that start with a parenthesis:
-
-<pre>
-     ;(print or io.write)('done')
-</pre>
-
-<p>
-A block can be explicitly delimited to produce a single statement:
-
-<pre>
-	stat ::= <b>do</b> block <b>end</b>
-</pre><p>
-Explicit blocks are useful
-to control the scope of variable declarations.
-Explicit blocks are also sometimes used to
-add a <b>return</b> statement in the middle
-of another block (see <a href="#3.3.4">&sect;3.3.4</a>).
-
-
-
-
-
-<h3>3.3.2 &ndash; <a name="3.3.2">Chunks</a></h3>
-
-<p>
-The unit of compilation of Lua is called a <em>chunk</em>.
-Syntactically,
-a chunk is simply a block:
-
-<pre>
-	chunk ::= block
-</pre>
-
-<p>
-Lua handles a chunk as the body of an anonymous function
-with a variable number of arguments
-(see <a href="#3.4.10">&sect;3.4.10</a>).
-As such, chunks can define local variables,
-receive arguments, and return values.
-Moreover, such anonymous function is compiled as in the
-scope of an external local variable called <code>_ENV</code> (see <a href="#2.2">&sect;2.2</a>).
-The resulting function always has <code>_ENV</code> as its only upvalue,
-even if it does not use that variable.
-
-
-<p>
-A chunk can be stored in a file or in a string inside the host program.
-To execute a chunk,
-Lua first precompiles the chunk into instructions for a virtual machine,
-and then it executes the compiled code
-with an interpreter for the virtual machine.
-
-
-<p>
-Chunks can also be precompiled into binary form;
-see program <code>luac</code> for details.
-Programs in source and compiled forms are interchangeable;
-Lua automatically detects the file type and acts accordingly.
-
-
-
-
-
-
-<h3>3.3.3 &ndash; <a name="3.3.3">Assignment</a></h3>
-
-<p>
-Lua allows multiple assignments.
-Therefore, the syntax for assignment
-defines a list of variables on the left side
-and a list of expressions on the right side.
-The elements in both lists are separated by commas:
-
-<pre>
-	stat ::= varlist &lsquo;<b>=</b>&rsquo; explist
-	varlist ::= var {&lsquo;<b>,</b>&rsquo; var}
-	explist ::= exp {&lsquo;<b>,</b>&rsquo; exp}
-</pre><p>
-Expressions are discussed in <a href="#3.4">&sect;3.4</a>.
-
-
-<p>
-Before the assignment,
-the list of values is <em>adjusted</em> to the length of
-the list of variables.
-If there are more values than needed,
-the excess values are thrown away.
-If there are fewer values than needed,
-the list is extended with as many  <b>nil</b>'s as needed.
-If the list of expressions ends with a function call,
-then all values returned by that call enter the list of values,
-before the adjustment
-(except when the call is enclosed in parentheses; see <a href="#3.4">&sect;3.4</a>).
-
-
-<p>
-The assignment statement first evaluates all its expressions
-and only then are the assignments performed.
-Thus the code
-
-<pre>
-     i = 3
-     i, a[i] = i+1, 20
-</pre><p>
-sets <code>a[3]</code> to 20, without affecting <code>a[4]</code>
-because the <code>i</code> in <code>a[i]</code> is evaluated (to 3)
-before it is assigned&nbsp;4.
-Similarly, the line
-
-<pre>
-     x, y = y, x
-</pre><p>
-exchanges the values of <code>x</code> and <code>y</code>,
-and
-
-<pre>
-     x, y, z = y, z, x
-</pre><p>
-cyclically permutes the values of <code>x</code>, <code>y</code>, and <code>z</code>.
-
-
-<p>
-The meaning of assignments to global variables
-and table fields can be changed via metatables.
-An assignment to an indexed variable <code>t[i] = val</code> is equivalent to
-<code>settable_event(t,i,val)</code>.
-(See <a href="#2.4">&sect;2.4</a> for a complete description of the
-<code>settable_event</code> function.
-This function is not defined or callable in Lua.
-We use it here only for explanatory purposes.)
-
-
-<p>
-An assignment to a global variable <code>x = val</code>
-is equivalent to the assignment
-<code>_ENV.x = val</code> (see <a href="#2.2">&sect;2.2</a>).
-
-
-
-
-
-<h3>3.3.4 &ndash; <a name="3.3.4">Control Structures</a></h3><p>
-The control structures
-<b>if</b>, <b>while</b>, and <b>repeat</b> have the usual meaning and
-familiar syntax:
-
-
-
-
-<pre>
-	stat ::= <b>while</b> exp <b>do</b> block <b>end</b>
-	stat ::= <b>repeat</b> block <b>until</b> exp
-	stat ::= <b>if</b> exp <b>then</b> block {<b>elseif</b> exp <b>then</b> block} [<b>else</b> block] <b>end</b>
-</pre><p>
-Lua also has a <b>for</b> statement, in two flavors (see <a href="#3.3.5">&sect;3.3.5</a>).
-
-
-<p>
-The condition expression of a
-control structure can return any value.
-Both <b>false</b> and <b>nil</b> are considered false.
-All values different from <b>nil</b> and <b>false</b> are considered true
-(in particular, the number 0 and the empty string are also true).
-
-
-<p>
-In the <b>repeat</b>&ndash;<b>until</b> loop,
-the inner block does not end at the <b>until</b> keyword,
-but only after the condition.
-So, the condition can refer to local variables
-declared inside the loop block.
-
-
-<p>
-The <b>goto</b> statement transfers the program control to a label.
-For syntactical reasons,
-labels in Lua are considered statements too:
-
-
-
-<pre>
-	stat ::= <b>goto</b> Name
-	stat ::= label
-	label ::= &lsquo;<b>::</b>&rsquo; Name &lsquo;<b>::</b>&rsquo;
-</pre>
-
-<p>
-A label is visible in the entire block where it is defined,
-except
-inside nested blocks where a label with the same name is defined and
-inside nested functions.
-A goto may jump to any visible label as long as it does not
-enter into the scope of a local variable.
-
-
-<p>
-Labels and empty statements are called <em>void statements</em>,
-as they perform no actions.
-
-
-<p>
-The <b>break</b> statement terminates the execution of a
-<b>while</b>, <b>repeat</b>, or <b>for</b> loop,
-skipping to the next statement after the loop:
-
-
-<pre>
-	stat ::= <b>break</b>
-</pre><p>
-A <b>break</b> ends the innermost enclosing loop.
-
-
-<p>
-The <b>return</b> statement is used to return values
-from a function or a chunk (which is a function in disguise).
-
-Functions can return more than one value,
-so the syntax for the <b>return</b> statement is
-
-<pre>
-	stat ::= <b>return</b> [explist] [&lsquo;<b>;</b>&rsquo;]
-</pre>
-
-<p>
-The <b>return</b> statement can only be written
-as the last statement of a block.
-If it is really necessary to <b>return</b> in the middle of a block,
-then an explicit inner block can be used,
-as in the idiom <code>do return end</code>,
-because now <b>return</b> is the last statement in its (inner) block.
-
-
-
-
-
-<h3>3.3.5 &ndash; <a name="3.3.5">For Statement</a></h3>
-
-<p>
-
-The <b>for</b> statement has two forms:
-one numeric and one generic.
-
-
-<p>
-The numeric <b>for</b> loop repeats a block of code while a
-control variable runs through an arithmetic progression.
-It has the following syntax:
-
-<pre>
-	stat ::= <b>for</b> Name &lsquo;<b>=</b>&rsquo; exp &lsquo;<b>,</b>&rsquo; exp [&lsquo;<b>,</b>&rsquo; exp] <b>do</b> block <b>end</b>
-</pre><p>
-The <em>block</em> is repeated for <em>name</em> starting at the value of
-the first <em>exp</em>, until it passes the second <em>exp</em> by steps of the
-third <em>exp</em>.
-More precisely, a <b>for</b> statement like
-
-<pre>
-     for v = <em>e1</em>, <em>e2</em>, <em>e3</em> do <em>block</em> end
-</pre><p>
-is equivalent to the code:
-
-<pre>
-     do
-       local <em>var</em>, <em>limit</em>, <em>step</em> = tonumber(<em>e1</em>), tonumber(<em>e2</em>), tonumber(<em>e3</em>)
-       if not (<em>var</em> and <em>limit</em> and <em>step</em>) then error() end
-       while (<em>step</em> &gt; 0 and <em>var</em> &lt;= <em>limit</em>) or (<em>step</em> &lt;= 0 and <em>var</em> &gt;= <em>limit</em>) do
-         local v = <em>var</em>
-         <em>block</em>
-         <em>var</em> = <em>var</em> + <em>step</em>
-       end
-     end
-</pre><p>
-Note the following:
-
-<ul>
-
-<li>
-All three control expressions are evaluated only once,
-before the loop starts.
-They must all result in numbers.
-</li>
-
-<li>
-<code><em>var</em></code>, <code><em>limit</em></code>, and <code><em>step</em></code> are invisible variables.
-The names shown here are for explanatory purposes only.
-</li>
-
-<li>
-If the third expression (the step) is absent,
-then a step of&nbsp;1 is used.
-</li>
-
-<li>
-You can use <b>break</b> to exit a <b>for</b> loop.
-</li>
-
-<li>
-The loop variable <code>v</code> is local to the loop;
-you cannot use its value after the <b>for</b> ends or is broken.
-If you need this value,
-assign it to another variable before breaking or exiting the loop.
-</li>
-
-</ul>
-
-<p>
-The generic <b>for</b> statement works over functions,
-called <em>iterators</em>.
-On each iteration, the iterator function is called to produce a new value,
-stopping when this new value is <b>nil</b>.
-The generic <b>for</b> loop has the following syntax:
-
-<pre>
-	stat ::= <b>for</b> namelist <b>in</b> explist <b>do</b> block <b>end</b>
-	namelist ::= Name {&lsquo;<b>,</b>&rsquo; Name}
-</pre><p>
-A <b>for</b> statement like
-
-<pre>
-     for <em>var_1</em>, &middot;&middot;&middot;, <em>var_n</em> in <em>explist</em> do <em>block</em> end
-</pre><p>
-is equivalent to the code:
-
-<pre>
-     do
-       local <em>f</em>, <em>s</em>, <em>var</em> = <em>explist</em>
-       while true do
-         local <em>var_1</em>, &middot;&middot;&middot;, <em>var_n</em> = <em>f</em>(<em>s</em>, <em>var</em>)
-         if <em>var_1</em> == nil then break end
-         <em>var</em> = <em>var_1</em>
-         <em>block</em>
-       end
-     end
-</pre><p>
-Note the following:
-
-<ul>
-
-<li>
-<code><em>explist</em></code> is evaluated only once.
-Its results are an <em>iterator</em> function,
-a <em>state</em>,
-and an initial value for the first <em>iterator variable</em>.
-</li>
-
-<li>
-<code><em>f</em></code>, <code><em>s</em></code>, and <code><em>var</em></code> are invisible variables.
-The names are here for explanatory purposes only.
-</li>
-
-<li>
-You can use <b>break</b> to exit a <b>for</b> loop.
-</li>
-
-<li>
-The loop variables <code><em>var_i</em></code> are local to the loop;
-you cannot use their values after the <b>for</b> ends.
-If you need these values,
-then assign them to other variables before breaking or exiting the loop.

-<h3>3.3.6 &ndash; <a name="3.3.6">Function Calls as Statements</a></h3><p>
-To allow possible side-effects,
-function calls can be executed as statements:
-
-<pre>
-	stat ::= functioncall
-</pre><p>
-In this case, all returned values are thrown away.
-Function calls are explained in <a href="#3.4.9">&sect;3.4.9</a>.
-
-
-
-
-
-<h3>3.3.7 &ndash; <a name="3.3.7">Local Declarations</a></h3><p>
-Local variables can be declared anywhere inside a block.
-The declaration can include an initial assignment:
-
-<pre>
-	stat ::= <b>local</b> namelist [&lsquo;<b>=</b>&rsquo; explist]
-</pre><p>
-If present, an initial assignment has the same semantics
-of a multiple assignment (see <a href="#3.3.3">&sect;3.3.3</a>).
-Otherwise, all variables are initialized with <b>nil</b>.
-
-
-<p>
-A chunk is also a block (see <a href="#3.3.2">&sect;3.3.2</a>),
-and so local variables can be declared in a chunk outside any explicit block.
-
-
-<p>
-The visibility rules for local variables are explained in <a href="#3.5">&sect;3.5</a>.

-<h2>3.4 &ndash; <a name="3.4">Expressions</a></h2>
-
-<p>
-The basic expressions in Lua are the following:
-
-<pre>
-	exp ::= prefixexp
-	exp ::= <b>nil</b> | <b>false</b> | <b>true</b>
-	exp ::= Number
-	exp ::= String
-	exp ::= functiondef
-	exp ::= tableconstructor
-	exp ::= &lsquo;<b>...</b>&rsquo;
-	exp ::= exp binop exp
-	exp ::= unop exp
-	prefixexp ::= var | functioncall | &lsquo;<b>(</b>&rsquo; exp &lsquo;<b>)</b>&rsquo;
-</pre>
-
-<p>
-Numbers and literal strings are explained in <a href="#3.1">&sect;3.1</a>;
-variables are explained in <a href="#3.2">&sect;3.2</a>;
-function definitions are explained in <a href="#3.4.10">&sect;3.4.10</a>;
-function calls are explained in <a href="#3.4.9">&sect;3.4.9</a>;
-table constructors are explained in <a href="#3.4.8">&sect;3.4.8</a>.
-Vararg expressions,
-denoted by three dots ('<code>...</code>'), can only be used when
-directly inside a vararg function;
-they are explained in <a href="#3.4.10">&sect;3.4.10</a>.
-
-
-<p>
-Binary operators comprise arithmetic operators (see <a href="#3.4.1">&sect;3.4.1</a>),
-relational operators (see <a href="#3.4.3">&sect;3.4.3</a>), logical operators (see <a href="#3.4.4">&sect;3.4.4</a>),
-and the concatenation operator (see <a href="#3.4.5">&sect;3.4.5</a>).
-Unary operators comprise the unary minus (see <a href="#3.4.1">&sect;3.4.1</a>),
-the unary <b>not</b> (see <a href="#3.4.4">&sect;3.4.4</a>),
-and the unary <em>length operator</em> (see <a href="#3.4.6">&sect;3.4.6</a>).
-
-
-<p>
-Both function calls and vararg expressions can result in multiple values.
-If a function call is used as a statement (see <a href="#3.3.6">&sect;3.3.6</a>),
-then its return list is adjusted to zero elements,
-thus discarding all returned values.
-If an expression is used as the last (or the only) element
-of a list of expressions,
-then no adjustment is made
-(unless the expression is enclosed in parentheses).
-In all other contexts,
-Lua adjusts the result list to one element,
-either discarding all values except the first one
-or adding a single <b>nil</b> if there are no values.
-
-
-<p>
-Here are some examples:
-
-<pre>
-     f()                -- adjusted to 0 results
-     g(f(), x)          -- f() is adjusted to 1 result
-     g(x, f())          -- g gets x plus all results from f()
-     a,b,c = f(), x     -- f() is adjusted to 1 result (c gets nil)
-     a,b = ...          -- a gets the first vararg parameter, b gets
-                        -- the second (both a and b can get nil if there
-                        -- is no corresponding vararg parameter)
-     
-     a,b,c = x, f()     -- f() is adjusted to 2 results
-     a,b,c = f()        -- f() is adjusted to 3 results
-     return f()         -- returns all results from f()
-     return ...         -- returns all received vararg parameters
-     return x,y,f()     -- returns x, y, and all results from f()
-     {f()}              -- creates a list with all results from f()
-     {...}              -- creates a list with all vararg parameters
-     {f(), nil}         -- f() is adjusted to 1 result
-</pre>
-
-<p>
-Any expression enclosed in parentheses always results in only one value.
-Thus,
-<code>(f(x,y,z))</code> is always a single value,
-even if <code>f</code> returns several values.
-(The value of <code>(f(x,y,z))</code> is the first value returned by <code>f</code>
-or <b>nil</b> if <code>f</code> does not return any values.)
-
-
-
-<h3>3.4.1 &ndash; <a name="3.4.1">Arithmetic Operators</a></h3><p>
-Lua supports the usual arithmetic operators:
-the binary <code>+</code> (addition),
-<code>-</code> (subtraction), <code>*</code> (multiplication),
-<code>/</code> (division), <code>%</code> (modulo), and <code>^</code> (exponentiation);
-and unary <code>-</code> (mathematical negation).
-If the operands are numbers, or strings that can be converted to
-numbers (see <a href="#3.4.2">&sect;3.4.2</a>),
-then all operations have the usual meaning.
-Exponentiation works for any exponent.
-For instance, <code>x^(-0.5)</code> computes the inverse of the square root of <code>x</code>.
-Modulo is defined as
-
-<pre>
-     a % b == a - math.floor(a/b)*b
-</pre><p>
-That is, it is the remainder of a division that rounds
-the quotient towards minus infinity.
-
-
-
-
-
-<h3>3.4.2 &ndash; <a name="3.4.2">Coercion</a></h3>
-
-<p>
-Lua provides automatic conversion between
-string and number values at run time.
-Any arithmetic operation applied to a string tries to convert
-this string to a number, following the rules of the Lua lexer.
-(The string may have leading and trailing spaces and a sign.)
-Conversely, whenever a number is used where a string is expected,
-the number is converted to a string, in a reasonable format.
-For complete control over how numbers are converted to strings,
-use the <code>format</code> function from the string library
-(see <a href="#pdf-string.format"><code>string.format</code></a>).
-
-
-
-
-
-<h3>3.4.3 &ndash; <a name="3.4.3">Relational Operators</a></h3><p>
-The relational operators in Lua are
-
-<pre>
-     ==    ~=    &lt;     &gt;     &lt;=    &gt;=
-</pre><p>
-These operators always result in <b>false</b> or <b>true</b>.
-
-
-<p>
-Equality (<code>==</code>) first compares the type of its operands.
-If the types are different, then the result is <b>false</b>.
-Otherwise, the values of the operands are compared.
-Numbers and strings are compared in the usual way.
-Tables, userdata, and threads
-are compared by reference:
-two objects are considered equal only if they are the same object.
-Every time you create a new object
-(a table, userdata, or thread),
-this new object is different from any previously existing object.
-Closures with the same reference are always equal.
-Closures with any detectable difference
-(different behavior, different definition) are always different.
-
-
-<p>
-You can change the way that Lua compares tables and userdata
-by using the "eq" metamethod (see <a href="#2.4">&sect;2.4</a>).
-
-
-<p>
-The conversion rules of <a href="#3.4.2">&sect;3.4.2</a>
-do not apply to equality comparisons.
-Thus, <code>"0"==0</code> evaluates to <b>false</b>,
-and <code>t[0]</code> and <code>t["0"]</code> denote different
-entries in a table.
-
-
-<p>
-The operator <code>~=</code> is exactly the negation of equality (<code>==</code>).
-
-
-<p>
-The order operators work as follows.
-If both arguments are numbers, then they are compared as such.
-Otherwise, if both arguments are strings,
-then their values are compared according to the current locale.
-Otherwise, Lua tries to call the "lt" or the "le"
-metamethod (see <a href="#2.4">&sect;2.4</a>).
-A comparison <code>a &gt; b</code> is translated to <code>b &lt; a</code>
-and <code>a &gt;= b</code> is translated to <code>b &lt;= a</code>.
-
-
-
-
-
-<h3>3.4.4 &ndash; <a name="3.4.4">Logical Operators</a></h3><p>
-The logical operators in Lua are
-<b>and</b>, <b>or</b>, and <b>not</b>.
-Like the control structures (see <a href="#3.3.4">&sect;3.3.4</a>),
-all logical operators consider both <b>false</b> and <b>nil</b> as false
-and anything else as true.
-
-
-<p>
-The negation operator <b>not</b> always returns <b>false</b> or <b>true</b>.
-The conjunction operator <b>and</b> returns its first argument
-if this value is <b>false</b> or <b>nil</b>;
-otherwise, <b>and</b> returns its second argument.
-The disjunction operator <b>or</b> returns its first argument
-if this value is different from <b>nil</b> and <b>false</b>;
-otherwise, <b>or</b> returns its second argument.
-Both <b>and</b> and <b>or</b> use short-cut evaluation;
-that is,
-the second operand is evaluated only if necessary.
-Here are some examples:
-
-<pre>
-     10 or 20            --&gt; 10
-     10 or error()       --&gt; 10
-     nil or "a"          --&gt; "a"
-     nil and 10          --&gt; nil
-     false and error()   --&gt; false
-     false and nil       --&gt; false
-     false or nil        --&gt; nil
-     10 and 20           --&gt; 20
-</pre><p>
-(In this manual,
-<code>--&gt;</code> indicates the result of the preceding expression.)
-
-
-
-
-
-<h3>3.4.5 &ndash; <a name="3.4.5">Concatenation</a></h3><p>
-The string concatenation operator in Lua is
-denoted by two dots ('<code>..</code>').
-If both operands are strings or numbers, then they are converted to
-strings according to the rules mentioned in <a href="#3.4.2">&sect;3.4.2</a>.
-Otherwise, the <code>__concat</code> metamethod is called (see <a href="#2.4">&sect;2.4</a>).
-
-
-
-
-
-<h3>3.4.6 &ndash; <a name="3.4.6">The Length Operator</a></h3>
-
-<p>
-The length operator is denoted by the unary prefix operator <code>#</code>.
-The length of a string is its number of bytes
-(that is, the usual meaning of string length when each
-character is one byte).
-
-
-<p>
-A program can modify the behavior of the length operator for
-any value but strings through the <code>__len</code> metamethod (see <a href="#2.4">&sect;2.4</a>).
-
-
-<p>
-Unless a <code>__len</code> metamethod is given,
-the length of a table <code>t</code> is only defined if the
-table is a <em>sequence</em>,
-that is,
-the set of its positive numeric keys is equal to <em>{1..n}</em>
-for some non-negative integer <em>n</em>.
-In that case, <em>n</em> is its length.
-Note that a table like
-
-<pre>
-     {10, 20, nil, 40}
-</pre><p>
-is not a sequence, because it has the key <code>4</code>
-but does not have the key <code>3</code>.
-(So, there is no <em>n</em> such that the set <em>{1..n}</em> is equal
-to the set of positive numeric keys of that table.)
-Note, however, that non-numeric keys do not interfere
-with whether a table is a sequence.
-
-
-
-
-
-<h3>3.4.7 &ndash; <a name="3.4.7">Precedence</a></h3><p>
-Operator precedence in Lua follows the table below,
-from lower to higher priority:
-
-<pre>
-     or
-     and
-     &lt;     &gt;     &lt;=    &gt;=    ~=    ==
-     ..
-     +     -
-     *     /     %
-     not   #     - (unary)
-     ^
-</pre><p>
-As usual,
-you can use parentheses to change the precedences of an expression.
-The concatenation ('<code>..</code>') and exponentiation ('<code>^</code>')
-operators are right associative.
-All other binary operators are left associative.
-
-
-
-
-
-<h3>3.4.8 &ndash; <a name="3.4.8">Table Constructors</a></h3><p>
-Table constructors are expressions that create tables.
-Every time a constructor is evaluated, a new table is created.
-A constructor can be used to create an empty table
-or to create a table and initialize some of its fields.
-The general syntax for constructors is
-
-<pre>
-	tableconstructor ::= &lsquo;<b>{</b>&rsquo; [fieldlist] &lsquo;<b>}</b>&rsquo;
-	fieldlist ::= field {fieldsep field} [fieldsep]
-	field ::= &lsquo;<b>[</b>&rsquo; exp &lsquo;<b>]</b>&rsquo; &lsquo;<b>=</b>&rsquo; exp | Name &lsquo;<b>=</b>&rsquo; exp | exp
-	fieldsep ::= &lsquo;<b>,</b>&rsquo; | &lsquo;<b>;</b>&rsquo;
-</pre>
-
-<p>
-Each field of the form <code>[exp1] = exp2</code> adds to the new table an entry
-with key <code>exp1</code> and value <code>exp2</code>.
-A field of the form <code>name = exp</code> is equivalent to
-<code>["name"] = exp</code>.
-Finally, fields of the form <code>exp</code> are equivalent to
-<code>[i] = exp</code>, where <code>i</code> are consecutive numerical integers,
-starting with 1.
-Fields in the other formats do not affect this counting.
-For example,
-
-<pre>
-     a = { [f(1)] = g; "x", "y"; x = 1, f(x), [30] = 23; 45 }
-</pre><p>
-is equivalent to
-
-<pre>
-     do
-       local t = {}
-       t[f(1)] = g
-       t[1] = "x"         -- 1st exp
-       t[2] = "y"         -- 2nd exp
-       t.x = 1            -- t["x"] = 1
-       t[3] = f(x)        -- 3rd exp
-       t[30] = 23
-       t[4] = 45          -- 4th exp
-       a = t
-     end
-</pre>
-
-<p>
-If the last field in the list has the form <code>exp</code>
-and the expression is a function call or a vararg expression,
-then all values returned by this expression enter the list consecutively
-(see <a href="#3.4.9">&sect;3.4.9</a>).
-
-
-<p>
-The field list can have an optional trailing separator,
-as a convenience for machine-generated code.
-
-
-
-
-
-<h3>3.4.9 &ndash; <a name="3.4.9">Function Calls</a></h3><p>
-A function call in Lua has the following syntax:
-
-<pre>
-	functioncall ::= prefixexp args
-</pre><p>
-In a function call,
-first prefixexp and args are evaluated.
-If the value of prefixexp has type <em>function</em>,
-then this function is called
-with the given arguments.
-Otherwise, the prefixexp "call" metamethod is called,
-having as first parameter the value of prefixexp,
-followed by the original call arguments
-(see <a href="#2.4">&sect;2.4</a>).
-
-
-<p>
-The form
-
-<pre>
-	functioncall ::= prefixexp &lsquo;<b>:</b>&rsquo; Name args
-</pre><p>
-can be used to call "methods".
-A call <code>v:name(<em>args</em>)</code>
-is syntactic sugar for <code>v.name(v,<em>args</em>)</code>,
-except that <code>v</code> is evaluated only once.
-
-
-<p>
-Arguments have the following syntax:
-
-<pre>
-	args ::= &lsquo;<b>(</b>&rsquo; [explist] &lsquo;<b>)</b>&rsquo;
-	args ::= tableconstructor
-	args ::= String
-</pre><p>
-All argument expressions are evaluated before the call.
-A call of the form <code>f{<em>fields</em>}</code> is
-syntactic sugar for <code>f({<em>fields</em>})</code>;
-that is, the argument list is a single new table.
-A call of the form <code>f'<em>string</em>'</code>
-(or <code>f"<em>string</em>"</code> or <code>f[[<em>string</em>]]</code>)
-is syntactic sugar for <code>f('<em>string</em>')</code>;
-that is, the argument list is a single literal string.
-
-
-<p>
-A call of the form <code>return <em>functioncall</em></code> is called
-a <em>tail call</em>.
-Lua implements <em>proper tail calls</em>
-(or <em>proper tail recursion</em>):
-in a tail call,
-the called function reuses the stack entry of the calling function.
-Therefore, there is no limit on the number of nested tail calls that
-a program can execute.
-However, a tail call erases any debug information about the
-calling function.
-Note that a tail call only happens with a particular syntax,
-where the <b>return</b> has one single function call as argument;
-this syntax makes the calling function return exactly
-the returns of the called function.
-So, none of the following examples are tail calls:
-
-<pre>
-     return (f(x))        -- results adjusted to 1
-     return 2 * f(x)
-     return x, f(x)       -- additional results
-     f(x); return         -- results discarded
-     return x or f(x)     -- results adjusted to 1
-</pre>
-
-
-
-
-<h3>3.4.10 &ndash; <a name="3.4.10">Function Definitions</a></h3>
-
-<p>
-The syntax for function definition is
-
-<pre>
-	functiondef ::= <b>function</b> funcbody
-	funcbody ::= &lsquo;<b>(</b>&rsquo; [parlist] &lsquo;<b>)</b>&rsquo; block <b>end</b>
-</pre>
-
-<p>
-The following syntactic sugar simplifies function definitions:
-
-<pre>
-	stat ::= <b>function</b> funcname funcbody
-	stat ::= <b>local</b> <b>function</b> Name funcbody
-	funcname ::= Name {&lsquo;<b>.</b>&rsquo; Name} [&lsquo;<b>:</b>&rsquo; Name]
-</pre><p>
-The statement
-
-<pre>
-     function f () <em>body</em> end
-</pre><p>
-translates to
-
-<pre>
-     f = function () <em>body</em> end
-</pre><p>
-The statement
-
-<pre>
-     function t.a.b.c.f () <em>body</em> end
-</pre><p>
-translates to
-
-<pre>
-     t.a.b.c.f = function () <em>body</em> end
-</pre><p>
-The statement
-
-<pre>
-     local function f () <em>body</em> end
-</pre><p>
-translates to
-
-<pre>
-     local f; f = function () <em>body</em> end
-</pre><p>
-not to
-
-<pre>
-     local f = function () <em>body</em> end
-</pre><p>
-(This only makes a difference when the body of the function
-contains references to <code>f</code>.)
-
-
-<p>
-A function definition is an executable expression,
-whose value has type <em>function</em>.
-When Lua precompiles a chunk,
-all its function bodies are precompiled too.
-Then, whenever Lua executes the function definition,
-the function is <em>instantiated</em> (or <em>closed</em>).
-This function instance (or <em>closure</em>)
-is the final value of the expression.
-
-
-<p>
-Parameters act as local variables that are
-initialized with the argument values:
-
-<pre>
-	parlist ::= namelist [&lsquo;<b>,</b>&rsquo; &lsquo;<b>...</b>&rsquo;] | &lsquo;<b>...</b>&rsquo;
-</pre><p>
-When a function is called,
-the list of arguments is adjusted to
-the length of the list of parameters,
-unless the function is a <em>vararg function</em>,
-which is indicated by three dots ('<code>...</code>')
-at the end of its parameter list.
-A vararg function does not adjust its argument list;
-instead, it collects all extra arguments and supplies them
-to the function through a <em>vararg expression</em>,
-which is also written as three dots.
-The value of this expression is a list of all actual extra arguments,
-similar to a function with multiple results.
-If a vararg expression is used inside another expression
-or in the middle of a list of expressions,
-then its return list is adjusted to one element.
-If the expression is used as the last element of a list of expressions,
-then no adjustment is made
-(unless that last expression is enclosed in parentheses).
-
-
-<p>
-As an example, consider the following definitions:
-
-<pre>
-     function f(a, b) end
-     function g(a, b, ...) end
-     function r() return 1,2,3 end
-</pre><p>
-Then, we have the following mapping from arguments to parameters and
-to the vararg expression:
-
-<pre>
-     CALL            PARAMETERS
-     
-     f(3)             a=3, b=nil
-     f(3, 4)          a=3, b=4
-     f(3, 4, 5)       a=3, b=4
-     f(r(), 10)       a=1, b=10
-     f(r())           a=1, b=2
-     
-     g(3)             a=3, b=nil, ... --&gt;  (nothing)
-     g(3, 4)          a=3, b=4,   ... --&gt;  (nothing)
-     g(3, 4, 5, 8)    a=3, b=4,   ... --&gt;  5  8
-     g(5, r())        a=5, b=1,   ... --&gt;  2  3
-</pre>
-
-<p>
-Results are returned using the <b>return</b> statement (see <a href="#3.3.4">&sect;3.3.4</a>).
-If control reaches the end of a function
-without encountering a <b>return</b> statement,
-then the function returns with no results.
-
-
-<p>
-
-There is a system-dependent limit on the number of values
-that a function may return.
-This limit is guaranteed to be larger than 1000.
-
-
-<p>
-The <em>colon</em> syntax
-is used for defining <em>methods</em>,
-that is, functions that have an implicit extra parameter <code>self</code>.
-Thus, the statement
-
-<pre>
-     function t.a.b.c:f (<em>params</em>) <em>body</em> end
-</pre><p>
-is syntactic sugar for
-
-<pre>
-     t.a.b.c.f = function (self, <em>params</em>) <em>body</em> end
-</pre>

-<h2>3.5 &ndash; <a name="3.5">Visibility Rules</a></h2>
-
-<p>
-
-Lua is a lexically scoped language.
-The scope of a local variable begins at the first statement after
-its declaration and lasts until the last non-void statement
-of the innermost block that includes the declaration.
-Consider the following example:
-
-<pre>
-     x = 10                -- global variable
-     do                    -- new block
-       local x = x         -- new 'x', with value 10
-       print(x)            --&gt; 10
-       x = x+1
-       do                  -- another block
-         local x = x+1     -- another 'x'
-         print(x)          --&gt; 12
-       end
-       print(x)            --&gt; 11
-     end
-     print(x)              --&gt; 10  (the global one)
-</pre>
-
-<p>
-Notice that, in a declaration like <code>local x = x</code>,
-the new <code>x</code> being declared is not in scope yet,
-and so the second <code>x</code> refers to the outside variable.
-
-
-<p>
-Because of the lexical scoping rules,
-local variables can be freely accessed by functions
-defined inside their scope.
-A local variable used by an inner function is called
-an <em>upvalue</em>, or <em>external local variable</em>,
-inside the inner function.
-
-
-<p>
-Notice that each execution of a <b>local</b> statement
-defines new local variables.
-Consider the following example:
-
-<pre>
-     a = {}
-     local x = 20
-     for i=1,10 do
-       local y = 0
-       a[i] = function () y=y+1; return x+y end
-     end
-</pre><p>
-The loop creates ten closures
-(that is, ten instances of the anonymous function).
-Each of these closures uses a different <code>y</code> variable,
-while all of them share the same <code>x</code>.
-
-
-
-
-
-<h1>4 &ndash; <a name="4">The Application Program Interface</a></h1>
-
-<p>
-
-This section describes the C&nbsp;API for Lua, that is,
-the set of C&nbsp;functions available to the host program to communicate
-with Lua.
-All API functions and related types and constants
-are declared in the header file <a name="pdf-lua.h"><code>lua.h</code></a>.
-
-
-<p>
-Even when we use the term "function",
-any facility in the API may be provided as a macro instead.
-Except where stated otherwise,
-all such macros use each of their arguments exactly once
-(except for the first argument, which is always a Lua state),
-and so do not generate any hidden side-effects.
-
-
-<p>
-As in most C&nbsp;libraries,
-the Lua API functions do not check their arguments for validity or consistency.
-However, you can change this behavior by compiling Lua
-with the macro <a name="pdf-LUA_USE_APICHECK"><code>LUA_USE_APICHECK</code></a> defined.
-
-
-
-<h2>4.1 &ndash; <a name="4.1">The Stack</a></h2>
-
-<p>
-Lua uses a <em>virtual stack</em> to pass values to and from C.
-Each element in this stack represents a Lua value
-(<b>nil</b>, number, string, etc.).
-
-
-<p>
-Whenever Lua calls C, the called function gets a new stack,
-which is independent of previous stacks and of stacks of
-C&nbsp;functions that are still active.
-This stack initially contains any arguments to the C&nbsp;function
-and it is where the C&nbsp;function pushes its results
-to be returned to the caller (see <a href="#lua_CFunction"><code>lua_CFunction</code></a>).
-
-
-<p>
-For convenience,
-most query operations in the API do not follow a strict stack discipline.
-Instead, they can refer to any element in the stack
-by using an <em>index</em>:
-A positive index represents an absolute stack position
-(starting at&nbsp;1);
-a negative index represents an offset relative to the top of the stack.
-More specifically, if the stack has <em>n</em> elements,
-then index&nbsp;1 represents the first element
-(that is, the element that was pushed onto the stack first)
-and
-index&nbsp;<em>n</em> represents the last element;
-index&nbsp;-1 also represents the last element
-(that is, the element at the&nbsp;top)
-and index <em>-n</em> represents the first element.
-
-
-
-
-
-<h2>4.2 &ndash; <a name="4.2">Stack Size</a></h2>
-
-<p>
-When you interact with the Lua API,
-you are responsible for ensuring consistency.
-In particular,
-<em>you are responsible for controlling stack overflow</em>.
-You can use the function <a href="#lua_checkstack"><code>lua_checkstack</code></a>
-to ensure that the stack has extra slots when pushing new elements.
-
-
-<p>
-Whenever Lua calls C,
-it ensures that the stack has at least <a name="pdf-LUA_MINSTACK"><code>LUA_MINSTACK</code></a> extra slots.
-<code>LUA_MINSTACK</code> is defined as 20,
-so that usually you do not have to worry about stack space
-unless your code has loops pushing elements onto the stack.
-
-
-<p>
-When you call a Lua function
-without a fixed number of results (see <a href="#lua_call"><code>lua_call</code></a>),
-Lua ensures that the stack has enough size for all results,
-but it does not ensure any extra space.
-So, before pushing anything in the stack after such a call
-you should use <a href="#lua_checkstack"><code>lua_checkstack</code></a>.
-
-
-
-
-
-<h2>4.3 &ndash; <a name="4.3">Valid and Acceptable Indices</a></h2>
-
-<p>
-Any function in the API that receives stack indices
-works only with <em>valid indices</em> or <em>acceptable indices</em>.
-
-
-<p>
-A <em>valid index</em> is an index that refers to a
-real position within the stack, that is,
-its position lies between&nbsp;1 and the stack top
-(<code>1 &le; abs(index) &le; top</code>).
-
-Usually, functions that can modify the value at an index
-require valid indices.
-
-
-<p>
-Unless otherwise noted,
-any function that accepts valid indices also accepts <em>pseudo-indices</em>,
-which represent some Lua values that are accessible to C&nbsp;code
-but which are not in the stack.
-Pseudo-indices are used to access the registry
-and the upvalues of a C&nbsp;function (see <a href="#4.4">&sect;4.4</a>).
-
-
-<p>
-Functions that do not need a specific stack position,
-but only a value in the stack (e.g., query functions),
-can be called with acceptable indices.
-An <em>acceptable index</em> can be any valid index,
-including the pseudo-indices,
-but it also can be any positive index after the stack top
-within the space allocated for the stack,
-that is, indices up to the stack size.
-(Note that 0 is never an acceptable index.)
-Except when noted otherwise,
-functions in the API work with acceptable indices.
-
-
-<p>
-Acceptable indices serve to avoid extra tests
-against the stack top when querying the stack.
-For instance, a C&nbsp;function can query its third argument
-without the need to first check whether there is a third argument,
-that is, without the need to check whether 3 is a valid index.
-
-
-<p>
-For functions that can be called with acceptable indices,
-any non-valid index is treated as if it
-contains a value of a virtual type <a name="pdf-LUA_TNONE"><code>LUA_TNONE</code></a>,
-which behaves like a nil value.
-
-
-
-
-
-<h2>4.4 &ndash; <a name="4.4">C Closures</a></h2>
-
-<p>
-When a C&nbsp;function is created,
-it is possible to associate some values with it,
-thus creating a <em>C&nbsp;closure</em>
-(see <a href="#lua_pushcclosure"><code>lua_pushcclosure</code></a>);
-these values are called <em>upvalues</em> and are
-accessible to the function whenever it is called.
-
-
-<p>
-Whenever a C&nbsp;function is called,
-its upvalues are located at specific pseudo-indices.
-These pseudo-indices are produced by the macro
-<a href="#lua_upvalueindex"><code>lua_upvalueindex</code></a>.
-The first value associated with a function is at position
-<code>lua_upvalueindex(1)</code>, and so on.
-Any access to <code>lua_upvalueindex(<em>n</em>)</code>,
-where <em>n</em> is greater than the number of upvalues of the
-current function (but not greater than 256),
-produces an acceptable but invalid index.
-
-
-
-
-
-<h2>4.5 &ndash; <a name="4.5">Registry</a></h2>
-
-<p>
-Lua provides a <em>registry</em>,
-a predefined table that can be used by any C&nbsp;code to
-store whatever Lua values it needs to store.
-The registry table is always located at pseudo-index
-<a name="pdf-LUA_REGISTRYINDEX"><code>LUA_REGISTRYINDEX</code></a>,
-which is a valid index.
-Any C&nbsp;library can store data into this table,
-but it should take care to choose keys
-that are different from those used
-by other libraries, to avoid collisions.
-Typically, you should use as key a string containing your library name,
-or a light userdata with the address of a C&nbsp;object in your code,
-or any Lua object created by your code.
-As with global names,
-string keys starting with an underscore followed by
-uppercase letters are reserved for Lua.
-
-
-<p>
-The integer keys in the registry are used by the reference mechanism,
-implemented by the auxiliary library,
-and by some predefined values.
-Therefore, integer keys should not be used for other purposes.
-
-
-<p>
-When you create a new Lua state,
-its registry comes with some predefined values.
-These predefined values are indexed with integer keys
-defined as constants in <code>lua.h</code>.
-The following constants are defined:
-
-<ul>
-<li><b><a name="pdf-LUA_RIDX_MAINTHREAD"><code>LUA_RIDX_MAINTHREAD</code></a>: </b> At this index the registry has
-the main thread of the state.
-(The main thread is the one created together with the state.)
-</li>
-
-<li><b><a name="pdf-LUA_RIDX_GLOBALS"><code>LUA_RIDX_GLOBALS</code></a>: </b> At this index the registry has
-the global environment.
-</li>
-</ul>
-
-
-
-
-<h2>4.6 &ndash; <a name="4.6">Error Handling in C</a></h2>
-
-<p>
-Internally, Lua uses the C <code>longjmp</code> facility to handle errors.
-(You can also choose to use exceptions if you compile Lua as C++;
-search for <code>LUAI_THROW</code> in the source code.)
-When Lua faces any error
-(such as a memory allocation error, type errors, syntax errors,
-and runtime errors)
-it <em>raises</em> an error;
-that is, it does a long jump.
-A <em>protected environment</em> uses <code>setjmp</code>
-to set a recovery point;
-any error jumps to the most recent active recovery point.
-
-
-<p>
-If an error happens outside any protected environment,
-Lua calls a <em>panic function</em> (see <a href="#lua_atpanic"><code>lua_atpanic</code></a>)
-and then calls <code>abort</code>,
-thus exiting the host application.
-Your panic function can avoid this exit by
-never returning
-(e.g., doing a long jump to your own recovery point outside Lua).
-
-
-<p>
-The panic function runs as if it were a message handler (see <a href="#2.3">&sect;2.3</a>);
-in particular, the error message is at the top of the stack.
-However, there is no guarantees about stack space.
-To push anything on the stack,
-the panic function should first check the available space (see <a href="#4.2">&sect;4.2</a>).
-
-
-<p>
-Most functions in the API can throw an error,
-for instance due to a memory allocation error.
-The documentation for each function indicates whether
-it can throw errors.
-
-
-<p>
-Inside a C&nbsp;function you can throw an error by calling <a href="#lua_error"><code>lua_error</code></a>.
-
-
-
-
-
-<h2>4.7 &ndash; <a name="4.7">Handling Yields in C</a></h2>
-
-<p>
-Internally, Lua uses the C <code>longjmp</code> facility to yield a coroutine.
-Therefore, if a function <code>foo</code> calls an API function
-and this API function yields
-(directly or indirectly by calling another function that yields),
-Lua cannot return to <code>foo</code> any more,
-because the <code>longjmp</code> removes its frame from the C stack.
-
-
-<p>
-To avoid this kind of problem,
-Lua raises an error whenever it tries to yield across an API call,
-except for three functions:
-<a href="#lua_yieldk"><code>lua_yieldk</code></a>, <a href="#lua_callk"><code>lua_callk</code></a>, and <a href="#lua_pcallk"><code>lua_pcallk</code></a>.
-All those functions receive a <em>continuation function</em>
-(as a parameter called <code>k</code>) to continue execution after a yield.
-
-
-<p>
-We need to set some terminology to explain continuations.
-We have a C function called from Lua which we will call
-the <em>original function</em>.
-This original function then calls one of those three functions in the C API,
-which we will call the <em>callee function</em>,
-that then yields the current thread.
-(This can happen when the callee function is <a href="#lua_yieldk"><code>lua_yieldk</code></a>,
-or when the callee function is either <a href="#lua_callk"><code>lua_callk</code></a> or <a href="#lua_pcallk"><code>lua_pcallk</code></a>
-and the function called by them yields.)
-
-
-<p>
-Suppose the running thread yields while executing the callee function.
-After the thread resumes,
-it eventually will finish running the callee function.
-However,
-the callee function cannot return to the original function,
-because its frame in the C stack was destroyed by the yield.
-Instead, Lua calls a <em>continuation function</em>,
-which was given as an argument to the callee function.
-As the name implies,
-the continuation function should continue the task
-of the original function.
-
-
-<p>
-Lua treats the continuation function as if it were the original function.
-The continuation function receives the same Lua stack
-from the original function,
-in the same state it would be if the callee function had returned.
-(For instance,
-after a <a href="#lua_callk"><code>lua_callk</code></a> the function and its arguments are
-removed from the stack and replaced by the results from the call.)
-It also has the same upvalues.
-Whatever it returns is handled by Lua as if it were the return
-of the original function.
-
-
-<p>
-The only difference in the Lua state between the original function
-and its continuation is the result of a call to <a href="#lua_getctx"><code>lua_getctx</code></a>.
-
-
-
-
-
-<h2>4.8 &ndash; <a name="4.8">Functions and Types</a></h2>
-
-<p>
-Here we list all functions and types from the C&nbsp;API in
-alphabetical order.
-Each function has an indicator like this:
-<span class="apii">[-o, +p, <em>x</em>]</span>
-
-
-<p>
-The first field, <code>o</code>,
-is how many elements the function pops from the stack.
-The second field, <code>p</code>,
-is how many elements the function pushes onto the stack.
-(Any function always pushes its results after popping its arguments.)
-A field in the form <code>x|y</code> means the function can push (or pop)
-<code>x</code> or <code>y</code> elements,
-depending on the situation;
-an interrogation mark '<code>?</code>' means that
-we cannot know how many elements the function pops/pushes
-by looking only at its arguments
-(e.g., they may depend on what is on the stack).
-The third field, <code>x</code>,
-tells whether the function may throw errors:
-'<code>-</code>' means the function never throws any error;
-'<code>e</code>' means the function may throw errors;
-'<code>v</code>' means the function may throw an error on purpose.

-                             size_t nsize);</pre>
-
-<p>
-The type of the memory-allocation function used by Lua states.
-The allocator function must provide a
-functionality similar to <code>realloc</code>,
-but not exactly the same.
-Its arguments are
-<code>ud</code>, an opaque pointer passed to <a href="#lua_newstate"><code>lua_newstate</code></a>;
-<code>ptr</code>, a pointer to the block being allocated/reallocated/freed;
-<code>osize</code>, the original size of the block or some code about what
-is being allocated;
-<code>nsize</code>, the new size of the block.
-
-
-<p>
-When <code>ptr</code> is not <code>NULL</code>,
-<code>osize</code> is the size of the block pointed by <code>ptr</code>,
-that is, the size given when it was allocated or reallocated.
-
-
-<p>
-When <code>ptr</code> is <code>NULL</code>,
-<code>osize</code> encodes the kind of object that Lua is allocating.
-<code>osize</code> is any of
-<a href="#pdf-LUA_TSTRING"><code>LUA_TSTRING</code></a>, <a href="#pdf-LUA_TTABLE"><code>LUA_TTABLE</code></a>, <a href="#pdf-LUA_TFUNCTION"><code>LUA_TFUNCTION</code></a>,
-<a href="#pdf-LUA_TUSERDATA"><code>LUA_TUSERDATA</code></a>, or <a href="#pdf-LUA_TTHREAD"><code>LUA_TTHREAD</code></a> when (and only when)
-Lua is creating a new object of that type.
-When <code>osize</code> is some other value,
-Lua is allocating memory for something else.
-
-
-<p>
-Lua assumes the following behavior from the allocator function:
-
-
-<p>
-When <code>nsize</code> is zero,
-the allocator should behave like <code>free</code>
-and return <code>NULL</code>.
-
-
-<p>
-When <code>nsize</code> is not zero,
-the allocator should behave like <code>realloc</code>.
-The allocator returns <code>NULL</code>
-if and only if it cannot fulfill the request.
-Lua assumes that the allocator never fails when
-<code>osize &gt;= nsize</code>.
-
-
-<p>
-Here is a simple implementation for the allocator function.
-It is used in the auxiliary library by <a href="#luaL_newstate"><code>luaL_newstate</code></a>.
-
-<pre>
-     static void *l_alloc (void *ud, void *ptr, size_t osize,
-                                                size_t nsize) {
-       (void)ud;  (void)osize;  /* not used */
-       if (nsize == 0) {
-         free(ptr);
-         return NULL;
-       }
-       else
-         return realloc(ptr, nsize);
-     }
-</pre><p>
-Note that Standard&nbsp;C ensures
-that <code>free(NULL)</code> has no effect and that
-<code>realloc(NULL, size)</code> is equivalent to <code>malloc(size)</code>.
-This code assumes that <code>realloc</code> does not fail when shrinking a block.
-(Although Standard&nbsp;C does not ensure this behavior,
-it seems to be a safe assumption.)

-unless <code>nresults</code> is <a name="pdf-LUA_MULTRET"><code>LUA_MULTRET</code></a>.
-In this case, all results from the function are pushed.
-Lua takes care that the returned values fit into the stack space.
-The function results are pushed onto the stack in direct order
-(the first result is pushed first),
-so that after the call the last result is on the top of the stack.
-
-
-<p>
-Any error inside the called function is propagated upwards
-(with a <code>longjmp</code>).
-
-
-<p>
-The following example shows how the host program can do the
-equivalent to this Lua code:
-
-<pre>
-     a = f("how", t.x, 14)
-</pre><p>
-Here it is in&nbsp;C:
-
-<pre>
-     lua_getglobal(L, "f");                  /* function to be called */
-     lua_pushstring(L, "how");                        /* 1st argument */
-     lua_getglobal(L, "t");                    /* table to be indexed */
-     lua_getfield(L, -1, "x");        /* push result of t.x (2nd arg) */
-     lua_remove(L, -2);                  /* remove 't' from the stack */
-     lua_pushinteger(L, 14);                          /* 3rd argument */
-     lua_call(L, 3, 1);     /* call 'f' with 3 arguments and 1 result */
-     lua_setglobal(L, "a");                         /* set global 'a' */
-</pre><p>
-Note that the code above is "balanced":
-at its end, the stack is back to its original configuration.
-This is considered good programming practice.

-Type for C&nbsp;functions.
-
-
-<p>
-In order to communicate properly with Lua,
-a C&nbsp;function must use the following protocol,
-which defines the way parameters and results are passed:
-a C&nbsp;function receives its arguments from Lua in its stack
-in direct order (the first argument is pushed first).
-So, when the function starts,
-<code>lua_gettop(L)</code> returns the number of arguments received by the function.
-The first argument (if any) is at index 1
-and its last argument is at index <code>lua_gettop(L)</code>.
-To return values to Lua, a C&nbsp;function just pushes them onto the stack,
-in direct order (the first result is pushed first),
-and returns the number of results.
-Any other value in the stack below the results will be properly
-discarded by Lua.
-Like a Lua function, a C&nbsp;function called by Lua can also return
-many results.
-
-
-<p>
-As an example, the following function receives a variable number
-of numerical arguments and returns their average and sum:
-
-<pre>
-     static int foo (lua_State *L) {
-       int n = lua_gettop(L);    /* number of arguments */
-       lua_Number sum = 0;

-           lua_error(L);
-         }
-         sum += lua_tonumber(L, i);
-       }
-       lua_pushnumber(L, sum/n);        /* first result */
-       lua_pushnumber(L, sum);         /* second result */

-<code>lua_load</code> pushes the compiled chunk as a Lua
-function on top of the stack.
-Otherwise, it pushes an error message.
-
-
-<p>
-The return values of <code>lua_load</code> are:
-
-<ul>
-
-<li><b><a href="#pdf-LUA_OK"><code>LUA_OK</code></a>: </b> no errors;</li>
-
-<li><b><a name="pdf-LUA_ERRSYNTAX"><code>LUA_ERRSYNTAX</code></a>: </b>

-error while running a <code>__gc</code> metamethod.
-(This error has no relation with the chunk being loaded.
-It is generated by the garbage collector.)
-</li>
-
-</ul>
-
-<p>
-The <code>lua_load</code> function uses a user-supplied <code>reader</code> function
-to read the chunk (see <a href="#lua_Reader"><code>lua_Reader</code></a>).
-The <code>data</code> argument is an opaque value passed to the reader function.
-
-
-<p>
-The <code>source</code> argument gives a name to the chunk,
-which is used for error messages and in debug information (see <a href="#4.9">&sect;4.9</a>).
-
-
-<p>
-<code>lua_load</code> automatically detects whether the chunk is text or binary
-and loads it accordingly (see program <code>luac</code>).
-The string <code>mode</code> works as in function <a href="#pdf-load"><code>load</code></a>,
-with the addition that
-a <code>NULL</code> value is equivalent to the string "<code>bt</code>".
-
-
-<p>
-<code>lua_load</code> uses the stack internally,
-so the reader function should always leave the stack
-unmodified when returning.
-
-
-<p>
-If the resulting function has one upvalue,
-this upvalue is set to the value of the global environment
-stored at index <code>LUA_RIDX_GLOBALS</code> in the registry (see <a href="#4.5">&sect;4.5</a>).
-When loading main chunks,
-this upvalue will be the <code>_ENV</code> variable (see <a href="#2.2">&sect;2.2</a>).

-Calls a function in protected mode.
-
-
-<p>
-Both <code>nargs</code> and <code>nresults</code> have the same meaning as
-in <a href="#lua_call"><code>lua_call</code></a>.
-If there are no errors during the call,
-<a href="#lua_pcall"><code>lua_pcall</code></a> behaves exactly like <a href="#lua_call"><code>lua_call</code></a>.
-However, if there is any error,
-<a href="#lua_pcall"><code>lua_pcall</code></a> catches it,

-and returns an error code.
-Like <a href="#lua_call"><code>lua_call</code></a>,
-<a href="#lua_pcall"><code>lua_pcall</code></a> always removes the function
-and its arguments from the stack.
-
-
-<p>
-If <code>msgh</code> is 0,
-then the error message returned on the stack
-is exactly the original error message.
-Otherwise, <code>msgh</code> is the stack index of a
-<em>message handler</em>.
-(In the current implementation, this index cannot be a pseudo-index.)
-In case of runtime errors,
-this function will be called with the error message
-and its return value will be the message
-returned on the stack by <a href="#lua_pcall"><code>lua_pcall</code></a>.
-
-
-<p>
-Typically, the message handler is used to add more debug
-information to the error message, such as a stack traceback.
-Such information cannot be gathered after the return of <a href="#lua_pcall"><code>lua_pcall</code></a>,

-
-<p>
-Pushes a new C&nbsp;closure onto the stack.
-
-
-<p>
-When a C&nbsp;function is created,
-it is possible to associate some values with it,
-thus creating a C&nbsp;closure (see <a href="#4.4">&sect;4.4</a>);
-these values are then accessible to the function whenever it is called.
-To associate values with a C&nbsp;function,
-first these values should be pushed onto the stack
-(when there are multiple values, the first value is pushed first).
-Then <a href="#lua_pushcclosure"><code>lua_pushcclosure</code></a>
-is called to create and push the C&nbsp;function onto the stack,
-with the argument <code>n</code> telling how many values should be
-associated with the function.
-<a href="#lua_pushcclosure"><code>lua_pushcclosure</code></a> also pops these values from the stack.
-
-
-<p>
-The maximum value for <code>n</code> is 255.

-This function receives a pointer to a C function
-and pushes onto the stack a Lua value of type <code>function</code> that,
-when called, invokes the corresponding C&nbsp;function.
-
-

-Pushes onto the stack a formatted string
-and returns a pointer to this string.
-It is similar to the ISO&nbsp;C function <code>sprintf</code>,
-but has some important differences:

-The conversion specifiers are quite restricted.
-There are no flags, widths, or precisions.
-The conversion specifiers can only be
-'<code>%%</code>' (inserts a '<code>%</code>' in the string),
-'<code>%s</code>' (inserts a zero-terminated string, with no size restrictions),
-'<code>%f</code>' (inserts a <a href="#lua_Number"><code>lua_Number</code></a>),

-} lua_Debug;</pre>
-
-<p>
-A structure used to carry different pieces of
-information about a function or an activation record.
-<a href="#lua_getstack"><code>lua_getstack</code></a> fills only the private part
-of this structure, for later use.
-To fill the other fields of <a href="#lua_Debug"><code>lua_Debug</code></a> with useful information,
-call <a href="#lua_getinfo"><code>lua_getinfo</code></a>.
-
-
-<p>
-The fields of <a href="#lua_Debug"><code>lua_Debug</code></a> have the following meaning:
-
-<ul>
-
-<li><b><code>source</code>: </b>
-the source of the chunk that created the function.
-If <code>source</code> starts with a '<code>@</code>',
-it means that the function was defined in a file where
-the file name follows the '<code>@</code>'.
-If <code>source</code> starts with a '<code>=</code>',
-the remainder of its contents describe the source in a user-dependent manner.
-Otherwise,
-the function was defined in a string where
-<code>source</code> is that string.
-</li>
-
-<li><b><code>short_src</code>: </b>
-a "printable" version of <code>source</code>, to be used in error messages.
-</li>
-
-<li><b><code>linedefined</code>: </b>
-the line number where the definition of the function starts.
-</li>
-
-<li><b><code>lastlinedefined</code>: </b>
-the line number where the definition of the function ends.
-</li>
-
-<li><b><code>what</code>: </b>
-the string <code>"Lua"</code> if the function is a Lua function,
-<code>"C"</code> if it is a C&nbsp;function,
-<code>"main"</code> if it is the main part of a chunk.
-</li>
-
-<li><b><code>currentline</code>: </b>
-the current line where the given function is executing.
-When no line information is available,
-<code>currentline</code> is set to -1.
-</li>
-
-<li><b><code>name</code>: </b>
-a reasonable name for the given function.
-Because functions in Lua are first-class values,
-they do not have a fixed name:
-some functions can be the value of multiple global variables,
-while others can be stored only in a table field.
-The <code>lua_getinfo</code> function checks how the function was
-called to find a suitable name.
-If it cannot find a name,
-then <code>name</code> is set to <code>NULL</code>.
-</li>
-
-<li><b><code>namewhat</code>: </b>
-explains the <code>name</code> field.
-The value of <code>namewhat</code> can be
-<code>"global"</code>, <code>"local"</code>, <code>"method"</code>,
-<code>"field"</code>, <code>"upvalue"</code>, or <code>""</code> (the empty string),
-according to how the function was called.
-(Lua uses the empty string when no other option seems to apply.)
-</li>
-
-<li><b><code>istailcall</code>: </b>
-true if this function invocation was called by a tail call.
-In this case, the caller of this level is not in the stack.
-</li>
-
-<li><b><code>nups</code>: </b>
-the number of upvalues of the function.
-</li>
-
-<li><b><code>nparams</code>: </b>
-the number of fixed parameters of the function
-(always 0&nbsp;for C&nbsp;functions).
-</li>
-
-<li><b><code>isvararg</code>: </b>
-true if the function is a vararg function
-(always true for C&nbsp;functions).
-</li>
-
-</ul>

-
-<p>
-Gets information about a specific function or function invocation.
-
-
-<p>
-To get information about a function invocation,
-the parameter <code>ar</code> must be a valid activation record that was
-filled by a previous call to <a href="#lua_getstack"><code>lua_getstack</code></a> or
-given as argument to a hook (see <a href="#lua_Hook"><code>lua_Hook</code></a>).
-
-
-<p>
-To get information about a function you push it onto the stack
-and start the <code>what</code> string with the character '<code>&gt;</code>'.
-(In that case,
-<code>lua_getinfo</code> pops the function from the top of the stack.)
-For instance, to know in which line a function <code>f</code> was defined,
-you can write the following code:
-
-<pre>
-     lua_Debug ar;
-     lua_getglobal(L, "f");  /* get global 'f' */

-selects some fields of the structure <code>ar</code> to be filled or
-a value to be pushed on the stack:
-
-<ul>
-
-<li><b>'<code>n</code>': </b> fills in the field <code>name</code> and <code>namewhat</code>;

-<code>nups</code>, <code>nparams</code>, and <code>isvararg</code>;
-</li>
-
-<li><b>'<code>f</code>': </b>
-pushes onto the stack the function that is
-running at the given level;
-</li>
-
-<li><b>'<code>L</code>': </b>
-pushes onto the stack a table whose indices are the
-numbers of the lines that are valid on the function.
-(A <em>valid line</em> is a line with some associated code,
-that is, a line where you can put a break point.
-Non-valid lines include empty lines and comments.)
-</li>
-
-</ul>
-
-<p>
-This function returns 0 on error
-(for instance, an invalid option in <code>what</code>).

-<span class="apii">[-0, +(0|1), &ndash;]</span>
-<pre>const char *lua_getlocal (lua_State *L, lua_Debug *ar, int n);</pre>
-
-<p>
-Gets information about a local variable of
-a given activation record or a given function.
-
-
-<p>
-In the first case,
-the parameter <code>ar</code> must be a valid activation record that was
-filled by a previous call to <a href="#lua_getstack"><code>lua_getstack</code></a> or
-given as argument to a hook (see <a href="#lua_Hook"><code>lua_Hook</code></a>).
-The index <code>n</code> selects which local variable to inspect;
-see <a href="#pdf-debug.getlocal"><code>debug.getlocal</code></a> for details about variable indices
-and names.
-
-
-<p>
-<a href="#lua_getlocal"><code>lua_getlocal</code></a> pushes the variable's value onto the stack
-and returns its name.
-
-
-<p>
-In the second case, <code>ar</code> should be <code>NULL</code> and the function
-to be inspected must be at the top of the stack.
-In this case, only parameters of Lua functions are visible
-(as there is no information about what variables are active)
-and no values are pushed onto the stack.
-
-

-
-<p>
-This function fills parts of a <a href="#lua_Debug"><code>lua_Debug</code></a> structure with
-an identification of the <em>activation record</em>
-of the function executing at a given level.
-Level&nbsp;0 is the current running function,

-<pre>const char *lua_getupvalue (lua_State *L, int funcindex, int n);</pre>
-
-<p>
-Gets information about a closure's upvalue.
-(For Lua functions,
-upvalues are the external local variables that the function uses,
-and that are consequently included in its closure.)
-<a href="#lua_getupvalue"><code>lua_getupvalue</code></a> gets the index <code>n</code> of an upvalue,
-pushes the upvalue's value onto the stack,
-and returns its name.
-<code>funcindex</code> points to the closure in the stack.
-(Upvalues have no particular order,
-as they are active through the whole function.
-So, they are numbered in an arbitrary order.)
-
-
-<p>
-Returns <code>NULL</code> (and pushes nothing)
-when the index is greater than the number of upvalues.
-For C&nbsp;functions, this function uses the empty string <code>""</code>
-as a name for all upvalues.

-
-<hr><h3><a name="lua_Hook"><code>lua_Hook</code></a></h3>
-<pre>typedef void (*lua_Hook) (lua_State *L, lua_Debug *ar);</pre>
-
-<p>
-Type for debugging hook functions.
-
-
-<p>
-Whenever a hook is called, its <code>ar</code> argument has its field
-<code>event</code> set to the specific event that triggered the hook.
-Lua identifies these events with the following constants:
-<a name="pdf-LUA_HOOKCALL"><code>LUA_HOOKCALL</code></a>, <a name="pdf-LUA_HOOKRET"><code>LUA_HOOKRET</code></a>,
-<a name="pdf-LUA_HOOKTAILCALL"><code>LUA_HOOKTAILCALL</code></a>, <a name="pdf-LUA_HOOKLINE"><code>LUA_HOOKLINE</code></a>,
-and <a name="pdf-LUA_HOOKCOUNT"><code>LUA_HOOKCOUNT</code></a>.
-Moreover, for line events, the field <code>currentline</code> is also set.
-To get the value of any other field in <code>ar</code>,
-the hook must call <a href="#lua_getinfo"><code>lua_getinfo</code></a>.
-
-
-<p>
-For call events, <code>event</code> can be <code>LUA_HOOKCALL</code>,
-the normal value, or <code>LUA_HOOKTAILCALL</code>, for a tail call;
-in this case, there will be no corresponding return event.
-
-
-<p>
-While Lua is running a hook, it disables other calls to hooks.
-Therefore, if a hook calls back Lua to execute a function or a chunk,
-this execution occurs without any calls to hooks.
-
-
-<p>
-Hook functions cannot have continuations,
-that is, they cannot call <a href="#lua_yieldk"><code>lua_yieldk</code></a>,
-<a href="#lua_pcallk"><code>lua_pcallk</code></a>, or <a href="#lua_callk"><code>lua_callk</code></a> with a non-null <code>k</code>.
-
-
-<p>
-Hook functions can yield under the following conditions:
-Only count and line events can yield
-and they cannot yield any value;
-to yield a hook function must finish its execution
-calling <a href="#lua_yield"><code>lua_yield</code></a> with <code>nresults</code> equal to zero.

-
-<p>
-Sets the debugging hook function.
-
-
-<p>
-Argument <code>f</code> is the hook function.
-<code>mask</code> specifies on which events the hook will be called:
-it is formed by a bitwise or of the constants
-<a name="pdf-LUA_MASKCALL"><code>LUA_MASKCALL</code></a>,
-<a name="pdf-LUA_MASKRET"><code>LUA_MASKRET</code></a>,
-<a name="pdf-LUA_MASKLINE"><code>LUA_MASKLINE</code></a>,
-and <a name="pdf-LUA_MASKCOUNT"><code>LUA_MASKCOUNT</code></a>.
-The <code>count</code> argument is only meaningful when the mask
-includes <code>LUA_MASKCOUNT</code>.
-For each event, the hook is called as explained below:
-
-<ul>
-
-<li><b>The call hook: </b> is called when the interpreter calls a function.
-The hook is called just after Lua enters the new function,
-before the function gets its arguments.
-</li>
-
-<li><b>The return hook: </b> is called when the interpreter returns from a function.
-The hook is called just before Lua leaves the function.
-There is no standard way to access the values
-to be returned by the function.
-</li>
-
-<li><b>The line hook: </b> is called when the interpreter is about to
-start the execution of a new line of code,
-or when it jumps back in the code (even to the same line).
-(This event only happens while Lua is executing a Lua function.)
-</li>
-
-<li><b>The count hook: </b> is called after the interpreter executes every
-<code>count</code> instructions.
-(This event only happens while Lua is executing a Lua function.)
-</li>
-
-</ul>
-
-<p>
-A hook is disabled by setting <code>mask</code> to zero.

-<h1>5 &ndash; <a name="5">The Auxiliary Library</a></h1>
-
-<p>
-
-The <em>auxiliary library</em> provides several convenient functions
-to interface C with Lua.
-While the basic API provides the primitive functions for all
-interactions between C and Lua,
-the auxiliary library provides higher-level functions for some
-common tasks.
-
-
-<p>
-All functions and types from the auxiliary library
-are defined in header file <code>lauxlib.h</code> and
-have a prefix <code>luaL_</code>.
-
-
-<p>
-All functions in the auxiliary library are built on
-top of the basic API,
-and so they provide nothing that cannot be done with that API.
-Nevertheless, the use of the auxiliary library ensures
-more consistency to your code.
-
-
-<p>
-Several functions in the auxiliary library use internally some
-extra stack slots.
-When a function in the auxiliary library uses less than five slots,
-it does not check the stack size;
-it simply assumes that there are enough slots.
-
-
-<p>
-Several functions in the auxiliary library are used to
-check C&nbsp;function arguments.
-Because the error message is formatted for arguments
-(e.g., "<code>bad argument #1</code>"),
-you should not use these functions for other stack values.
-
-
-<p>
-Functions called <code>luaL_check*</code>
-always throw an error if the check is not satisfied.
-
-
-
-<h2>5.1 &ndash; <a name="5.1">Functions and Types</a></h2>
-
-<p>
-Here we list all functions and types from the auxiliary library
-in alphabetical order.

-
-<p>
-Type for a <em>string buffer</em>.
-
-
-<p>
-A string buffer allows C&nbsp;code to build Lua strings piecemeal.
-Its pattern of use is as follows:
-
-<ul>
-
-<li>First declare a variable <code>b</code> of type <a href="#luaL_Buffer"><code>luaL_Buffer</code></a>.</li>
-
-<li>Then initialize it with a call <code>luaL_buffinit(L, &amp;b)</code>.</li>
-
-<li>
-Then add string pieces to the buffer calling any of
-the <code>luaL_add*</code> functions.
-</li>
-
-<li>
-Finish by calling <code>luaL_pushresult(&amp;b)</code>.
-This call leaves the final string on the top of the stack.
-</li>
-
-</ul>
-
-<p>
-If you know beforehand the total size of the resulting string,
-you can use the buffer like this:
-
-<ul>
-
-<li>First declare a variable <code>b</code> of type <a href="#luaL_Buffer"><code>luaL_Buffer</code></a>.</li>
-
-<li>Then initialize it and preallocate a space of
-size <code>sz</code> with a call <code>luaL_buffinitsize(L, &amp;b, sz)</code>.</li>
-
-<li>Then copy the string into that space.</li>
-

-During its normal operation,

-So, while using a buffer, you cannot assume that you know where
-the top of the stack is.
-You can use the stack between successive calls to buffer operations
-as long as that use is balanced;
-that is,
-when you call a buffer operation,
-the stack is at the same level

-(The only exception to this rule is <a href="#luaL_addvalue"><code>luaL_addvalue</code></a>.)
-After calling <a href="#luaL_pushresult"><code>luaL_pushresult</code></a> the stack is back to its

-<h1>6 &ndash; <a name="6">Standard Libraries</a></h1>
-
-<p>
-The standard Lua libraries provide useful functions
-that are implemented directly through the C&nbsp;API.
-Some of these functions provide essential services to the language
-(e.g., <a href="#pdf-type"><code>type</code></a> and <a href="#pdf-getmetatable"><code>getmetatable</code></a>);
-others provide access to "outside" services (e.g., I/O);
-and others could be implemented in Lua itself,
-but are quite useful or have critical performance requirements that
-deserve an implementation in C (e.g., <a href="#pdf-table.sort"><code>table.sort</code></a>).
-
-
-<p>
-All libraries are implemented through the official C&nbsp;API
-and are provided as separate C&nbsp;modules.
-Currently, Lua has the following standard libraries:
-
-<ul>
-
-<li>basic library (<a href="#6.1">&sect;6.1</a>);</li>
-
-<li>coroutine library (<a href="#6.2">&sect;6.2</a>);</li>
-
-<li>package library (<a href="#6.3">&sect;6.3</a>);</li>
-
-<li>string manipulation (<a href="#6.4">&sect;6.4</a>);</li>
-
-<li>table manipulation (<a href="#6.5">&sect;6.5</a>);</li>
-
-<li>mathematical functions (<a href="#6.6">&sect;6.6</a>) (sin, log, etc.);</li>
-
-<li>bitwise operations (<a href="#6.7">&sect;6.7</a>);</li>
-
-<li>input and output (<a href="#6.8">&sect;6.8</a>);</li>
-
-<li>operating system facilities (<a href="#6.9">&sect;6.9</a>);</li>
-
-<li>debug facilities (<a href="#6.10">&sect;6.10</a>).</li>
-
-</ul><p>
-Except for the basic and the package libraries,
-each library provides all its functions as fields of a global table
-or as methods of its objects.
-
-
-<p>
-To have access to these libraries,
-the C&nbsp;host program should call the <a href="#luaL_openlibs"><code>luaL_openlibs</code></a> function,
-which opens all standard libraries.
-Alternatively,
-the host program can open them individually by using
-<a href="#luaL_requiref"><code>luaL_requiref</code></a> to call
-<a name="pdf-luaopen_base"><code>luaopen_base</code></a> (for the basic library),
-<a name="pdf-luaopen_package"><code>luaopen_package</code></a> (for the package library),
-<a name="pdf-luaopen_coroutine"><code>luaopen_coroutine</code></a> (for the coroutine library),
-<a name="pdf-luaopen_string"><code>luaopen_string</code></a> (for the string library),
-<a name="pdf-luaopen_table"><code>luaopen_table</code></a> (for the table library),
-<a name="pdf-luaopen_math"><code>luaopen_math</code></a> (for the mathematical library),
-<a name="pdf-luaopen_bit32"><code>luaopen_bit32</code></a> (for the bit library),
-<a name="pdf-luaopen_io"><code>luaopen_io</code></a> (for the I/O library),
-<a name="pdf-luaopen_os"><code>luaopen_os</code></a> (for the Operating System library),
-and <a name="pdf-luaopen_debug"><code>luaopen_debug</code></a> (for the debug library).
-These functions are declared in <a name="pdf-lualib.h"><code>lualib.h</code></a>.
-
-
-
-<h2>6.1 &ndash; <a name="6.1">Basic Functions</a></h2>
-
-<p>
-The basic library provides core functions to Lua.
-If you do not include this library in your application,
-you should check carefully whether you need to provide
-implementations for some of its facilities.
-
-
-<p>
-<hr><h3><a name="pdf-assert"><code>assert (v [, message])</code></a></h3>
-Issues an  error when
-the value of its argument <code>v</code> is false (i.e., <b>nil</b> or <b>false</b>);
-otherwise, returns all its arguments.
-<code>message</code> is an error message;
-when absent, it defaults to "assertion failed!"
-
-
-
-
-<p>
-<hr><h3><a name="pdf-collectgarbage"><code>collectgarbage ([opt [, arg]])</code></a></h3>
-
-
-<p>
-This function is a generic interface to the garbage collector.
-It performs different functions according to its first argument, <code>opt</code>:
-
-<ul>
-
-<li><b>"<code>collect</code>": </b>
-performs a full garbage-collection cycle.
-This is the default option.
-</li>
-
-<li><b>"<code>stop</code>": </b>
-stops automatic execution of the garbage collector.
-The collector will run only when explicitly invoked,
-until a call to restart it.
-</li>
-
-<li><b>"<code>restart</code>": </b>
-restarts automatic execution of the garbage collector.
-</li>
-
-<li><b>"<code>count</code>": </b>
-returns the total memory in use by Lua (in Kbytes) and
-a second value with the total memory in bytes modulo 1024.
-The first value has a fractional part,
-so the following equality is always true:
-
-<pre>
-     k, b = collectgarbage("count")
-     assert(k*1024 == math.floor(k)*1024 + b)
-</pre><p>
-(The second result is useful when Lua is compiled
-with a non floating-point type for numbers.)
-</li>
-
-<li><b>"<code>step</code>": </b>
-performs a garbage-collection step.
-The step "size" is controlled by <code>arg</code>
-(larger values mean more steps) in a non-specified way.
-If you want to control the step size
-you must experimentally tune the value of <code>arg</code>.
-Returns <b>true</b> if the step finished a collection cycle.
-</li>
-
-<li><b>"<code>setpause</code>": </b>
-sets <code>arg</code> as the new value for the <em>pause</em> of
-the collector (see <a href="#2.5">&sect;2.5</a>).
-Returns the previous value for <em>pause</em>.
-</li>
-
-<li><b>"<code>setstepmul</code>": </b>
-sets <code>arg</code> as the new value for the <em>step multiplier</em> of
-the collector (see <a href="#2.5">&sect;2.5</a>).
-Returns the previous value for <em>step</em>.
-</li>
-
-<li><b>"<code>isrunning</code>": </b>
-returns a boolean that tells whether the collector is running
-(i.e., not stopped).
-</li>
-
-<li><b>"<code>generational</code>": </b>
-changes the collector to generational mode.
-This is an experimental feature (see <a href="#2.5">&sect;2.5</a>).
-</li>
-
-<li><b>"<code>incremental</code>": </b>
-changes the collector to incremental mode.
-This is the default mode.
-</li>
-
-</ul>

-<hr><h3><a name="pdf-dofile"><code>dofile ([filename])</code></a></h3>
-Opens the named file and executes its contents as a Lua chunk.
-When called without arguments,
-<code>dofile</code> executes the contents of the standard input (<code>stdin</code>).
-Returns all values returned by the chunk.
-In case of errors, <code>dofile</code> propagates the error
-to its caller (that is, <code>dofile</code> does not run in protected mode).
-
-
-
-
-<p>
-<hr><h3><a name="pdf-error"><code>error (message [, level])</code></a></h3>
-Terminates the last protected function called
-and returns <code>message</code> as the error message.
-Function <code>error</code> never returns.
-
-
-<p>
-Usually, <code>error</code> adds some information about the error position
-at the beginning of the message, if the message is a string.
-The <code>level</code> argument specifies how to get the error position.
-With level&nbsp;1 (the default), the error position is where the
-<code>error</code> function was called.
-Level&nbsp;2 points the error to where the function
-that called <code>error</code> was called; and so on.
-Passing a level&nbsp;0 avoids the addition of error position information
-to the message.
-

-<hr><h3><a name="pdf-_G"><code>_G</code></a></h3>
-A global variable (not a function) that
-holds the global environment (see <a href="#2.2">&sect;2.2</a>).
-Lua itself does not use this variable;
-changing its value does not affect any environment,
-nor vice-versa.

-If <code>object</code> does not have a metatable, returns <b>nil</b>.
-Otherwise,
-if the object's metatable has a <code>"__metatable"</code> field,
-returns the associated value.
-Otherwise, returns the metatable of the given object.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-ipairs"><code>ipairs (t)</code></a></h3>
-
-
-<p>
-If <code>t</code> has a metamethod <code>__ipairs</code>,
-calls it with <code>t</code> as argument and returns the first three
-results from the call.
-
-
-<p>
-Otherwise,
-returns three values: an iterator function, the table <code>t</code>, and 0,
-so that the construction
-
-<pre>
-     for i,v in ipairs(t) do <em>body</em> end
-</pre><p>
-will iterate over the pairs (<code>1,t[1]</code>), (<code>2,t[2]</code>), ...,

-<hr><h3><a name="pdf-load"><code>load (ld [, source [, mode [, env]]])</code></a></h3>
-
-
-<p>
-Loads a chunk.
-
-
-<p>
-If <code>ld</code> is a string, the chunk is this string.
-If <code>ld</code> is a function,
-<code>load</code> calls it repeatedly to get the chunk pieces.
-Each call to <code>ld</code> must return a string that concatenates
-with previous results.
-A return of an empty string, <b>nil</b>, or no value signals the end of the chunk.
-
-
-<p>
-If there are no syntactic errors,
-returns the compiled chunk as a function;
-otherwise, returns <b>nil</b> plus the error message.
-
-
-<p>
-If the resulting function has upvalues,
-the first upvalue is set to the value of <code>env</code>,
-if that parameter is given,
-or to the value of the global environment.
-(When you load a main chunk,
-the resulting function will always have exactly one upvalue,
-the <code>_ENV</code> variable (see <a href="#2.2">&sect;2.2</a>).
-When you load a binary chunk created from a function (see <a href="#pdf-string.dump"><code>string.dump</code></a>),
-the resulting function can have arbitrary upvalues.)
-
-
-<p>
-<code>source</code> is used as the source of the chunk for error messages
-and debug information (see <a href="#4.9">&sect;4.9</a>).
-When absent,
-it defaults to <code>ld</code>, if <code>ld</code> is a string,
-or to "<code>=(load)</code>" otherwise.
-
-
-<p>
-The string <code>mode</code> controls whether the chunk can be text or binary
-(that is, a precompiled chunk).
-It may be the string "<code>b</code>" (only binary chunks),
-"<code>t</code>" (only text chunks),
-or "<code>bt</code>" (both binary and text).
-The default is "<code>bt</code>".

-
-
-<p>
-<hr><h3><a name="pdf-next"><code>next (table [, index])</code></a></h3>
-
-
-<p>
-Allows a program to traverse all fields of a table.
-Its first argument is a table and its second argument
-is an index in this table.
-<code>next</code> returns the next index of the table
-and its associated value.
-When called with <b>nil</b> as its second argument,
-<code>next</code> returns an initial index
-and its associated value.
-When called with the last index,
-or with <b>nil</b> in an empty table,
-<code>next</code> returns <b>nil</b>.
-If the second argument is absent, then it is interpreted as <b>nil</b>.
-In particular,
-you can use <code>next(t)</code> to check whether a table is empty.
-
-
-<p>
-The order in which the indices are enumerated is not specified,
-<em>even for numeric indices</em>.
-(To traverse a table in numeric order,
-use a numerical <b>for</b>.)
-
-
-<p>
-The behavior of <code>next</code> is undefined if,
-during the traversal,
-you assign any value to a non-existent field in the table.
-You may however modify existing fields.
-In particular, you may clear existing fields.

-<h2>6.3 &ndash; <a name="6.3">Modules</a></h2>
-
-<p>
-The package library provides basic
-facilities for loading modules in Lua.
-It exports one function directly in the global environment:
-<a href="#pdf-require"><code>require</code></a>.
-Everything else is exported in a table <a name="pdf-package"><code>package</code></a>.
-
-
-<p>
-<hr><h3><a name="pdf-require"><code>require (modname)</code></a></h3>
-
-
-<p>
-Loads the given module.
-The function starts by looking into the <a href="#pdf-package.loaded"><code>package.loaded</code></a> table
-to determine whether <code>modname</code> is already loaded.
-If it is, then <code>require</code> returns the value stored
-at <code>package.loaded[modname]</code>.
-Otherwise, it tries to find a <em>loader</em> for the module.
-
-
-<p>
-To find a loader,
-<code>require</code> is guided by the <a href="#pdf-package.searchers"><code>package.searchers</code></a> sequence.
-By changing this sequence,
-we can change how <code>require</code> looks for a module.
-The following explanation is based on the default configuration
-for <a href="#pdf-package.searchers"><code>package.searchers</code></a>.
-
-
-<p>
-First <code>require</code> queries <code>package.preload[modname]</code>.
-If it has a value,
-this value (which should be a function) is the loader.
-Otherwise <code>require</code> searches for a Lua loader using the
-path stored in <a href="#pdf-package.path"><code>package.path</code></a>.
-If that also fails, it searches for a C&nbsp;loader using the
-path stored in <a href="#pdf-package.cpath"><code>package.cpath</code></a>.
-If that also fails,
-it tries an <em>all-in-one</em> loader (see <a href="#pdf-package.searchers"><code>package.searchers</code></a>).
-
-
-<p>
-Once a loader is found,
-<code>require</code> calls the loader with two arguments:
-<code>modname</code> and an extra value dependent on how it got the loader.
-(If the loader came from a file,
-this extra value is the file name.)
-If the loader returns any non-nil value,
-<code>require</code> assigns the returned value to <code>package.loaded[modname]</code>.
-If the loader does not return a non-nil value and
-has not assigned any value to <code>package.loaded[modname]</code>,
-then <code>require</code> assigns <b>true</b> to this entry.
-In any case, <code>require</code> returns the
-final value of <code>package.loaded[modname]</code>.
-
-
-<p>
-If there is any error loading or running the module,
-or if it cannot find any loader for the module,
-then <code>require</code> raises an error.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-package.config"><code>package.config</code></a></h3>
-
-
-<p>
-A string describing some compile-time configurations for packages.
-This string is a sequence of lines:
-
-<ul>
-
-<li>The first line is the directory separator string.
-Default is '<code>\</code>' for Windows and '<code>/</code>' for all other systems.</li>
-
-<li>The second line is the character that separates templates in a path.
-Default is '<code>;</code>'.</li>
-
-<li>The third line is the string that marks the
-substitution points in a template.
-Default is '<code>?</code>'.</li>
-
-<li>The fourth line is a string that, in a path in Windows,
-is replaced by the executable's directory.
-Default is '<code>!</code>'.</li>
-
-<li>The fifth line is a mark to ignore all text before it
-when building the <code>luaopen_</code> function name.

-<hr><h3><a name="pdf-package.cpath"><code>package.cpath</code></a></h3>
-
-
-<p>
-The path used by <a href="#pdf-require"><code>require</code></a> to search for a C&nbsp;loader.
-
-
-<p>
-Lua initializes the C&nbsp;path <a href="#pdf-package.cpath"><code>package.cpath</code></a> in the same way
-it initializes the Lua path <a href="#pdf-package.path"><code>package.path</code></a>,
-using the environment variable <a name="pdf-LUA_CPATH_5_2"><code>LUA_CPATH_5_2</code></a>
-or the environment variable <a name="pdf-LUA_CPATH"><code>LUA_CPATH</code></a>
-or a default path defined in <code>luaconf.h</code>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-package.loaded"><code>package.loaded</code></a></h3>
-
-
-<p>
-A table used by <a href="#pdf-require"><code>require</code></a> to control which
-modules are already loaded.
-When you require a module <code>modname</code> and
-<code>package.loaded[modname]</code> is not false,
-<a href="#pdf-require"><code>require</code></a> simply returns the value stored there.
-
-
-<p>
-This variable is only a reference to the real table;
-assignments to this variable do not change the

-
-
-
-
-<p>
-<hr><h3><a name="pdf-package.loadlib"><code>package.loadlib (libname, funcname)</code></a></h3>

-Dynamically links the host program with the C&nbsp;library <code>libname</code>.
-
-
-<p>
-If <code>funcname</code> is "<code>*</code>",
-then it only links with the library,
-making the symbols exported by the library
-available to other dynamically linked libraries.
-Otherwise,
-it looks for a function <code>funcname</code> inside the library
-and returns this function as a C&nbsp;function.
-So, <code>funcname</code> must follow the <a href="#lua_CFunction"><code>lua_CFunction</code></a> prototype
-(see <a href="#lua_CFunction"><code>lua_CFunction</code></a>).
-
-
-<p>
-This is a low-level function.
-It completely bypasses the package and module system.
-Unlike <a href="#pdf-require"><code>require</code></a>,
-it does not perform any path searching and
-does not automatically adds extensions.
-<code>libname</code> must be the complete file name of the C&nbsp;library,
-including if necessary a path and an extension.
-<code>funcname</code> must be the exact name exported by the C&nbsp;library
-(which may depend on the C&nbsp;compiler and linker used).
-
-
-<p>
-This function is not supported by Standard&nbsp;C.
-As such, it is only available on some platforms
-(Windows, Linux, Mac OS X, Solaris, BSD,
-plus other Unix systems that support the <code>dlfcn</code> standard).
-
-
-
-
-<p>
-<hr><h3><a name="pdf-package.path"><code>package.path</code></a></h3>
-
-
-<p>
-The path used by <a href="#pdf-require"><code>require</code></a> to search for a Lua loader.
-
-
-<p>
-At start-up, Lua initializes this variable with
-the value of the environment variable <a name="pdf-LUA_PATH_5_2"><code>LUA_PATH_5_2</code></a> or
-the environment variable <a name="pdf-LUA_PATH"><code>LUA_PATH</code></a> or
-with a default path defined in <code>luaconf.h</code>,
-if those environment variables are not defined.
-Any "<code>;;</code>" in the value of the environment variable
-is replaced by the default path.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-package.preload"><code>package.preload</code></a></h3>
-
-
-<p>
-A table to store loaders for specific modules
-(see <a href="#pdf-require"><code>require</code></a>).
-
-
-<p>
-This variable is only a reference to the real table;
-assignments to this variable do not change the
-table used by <a href="#pdf-require"><code>require</code></a>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-package.searchers"><code>package.searchers</code></a></h3>
-
-
-<p>
-A table used by <a href="#pdf-require"><code>require</code></a> to control how to load modules.
-
-
-<p>
-Each entry in this table is a <em>searcher function</em>.
-When looking for a module,
-<a href="#pdf-require"><code>require</code></a> calls each of these searchers in ascending order,
-with the module name (the argument given to <a href="#pdf-require"><code>require</code></a>) as its
-sole parameter.
-The function can return another function (the module <em>loader</em>)
-plus an extra value that will be passed to that loader,
-or a string explaining why it did not find that module
-(or <b>nil</b> if it has nothing to say).
-
-
-<p>
-Lua initializes this table with four searcher functions.
-
-
-<p>
-The first searcher simply looks for a loader in the
-<a href="#pdf-package.preload"><code>package.preload</code></a> table.
-
-
-<p>
-The second searcher looks for a loader as a Lua library,
-using the path stored at <a href="#pdf-package.path"><code>package.path</code></a>.
-The search is done as described in function <a href="#pdf-package.searchpath"><code>package.searchpath</code></a>.
-
-
-<p>
-The third searcher looks for a loader as a C&nbsp;library,
-using the path given by the variable <a href="#pdf-package.cpath"><code>package.cpath</code></a>.
-Again,
-the search is done as described in function <a href="#pdf-package.searchpath"><code>package.searchpath</code></a>.
-For instance,
-if the C&nbsp;path is the string
-
-<pre>
-     "./?.so;./?.dll;/usr/local/?/init.so"
-</pre><p>
-the searcher for module <code>foo</code>
-will try to open the files <code>./foo.so</code>, <code>./foo.dll</code>,
-and <code>/usr/local/foo/init.so</code>, in that order.
-Once it finds a C&nbsp;library,
-this searcher first uses a dynamic link facility to link the
-application with the library.
-Then it tries to find a C&nbsp;function inside the library to
-be used as the loader.
-The name of this C&nbsp;function is the string "<code>luaopen_</code>"
-concatenated with a copy of the module name where each dot
-is replaced by an underscore.
-Moreover, if the module name has a hyphen,
-its prefix up to (and including) the first hyphen is removed.
-For instance, if the module name is <code>a.v1-b.c</code>,
-the function name will be <code>luaopen_b_c</code>.
-
-
-<p>
-The fourth searcher tries an <em>all-in-one loader</em>.
-It searches the C&nbsp;path for a library for
-the root name of the given module.
-For instance, when requiring <code>a.b.c</code>,
-it will search for a C&nbsp;library for <code>a</code>.
-If found, it looks into it for an open function for
-the submodule;
-in our example, that would be <code>luaopen_a_b_c</code>.
-With this facility, a package can pack several C&nbsp;submodules
-into one single library,
-with each submodule keeping its original open function.
-
-
-<p>
-All searchers except the first one (preload) return as the extra value
-the file name where the module was found,
-as returned by <a href="#pdf-package.searchpath"><code>package.searchpath</code></a>.
-The first searcher returns no extra value.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-package.searchpath"><code>package.searchpath (name, path [, sep [, rep]])</code></a></h3>
-
-
-<p>
-Searches for the given <code>name</code> in the given <code>path</code>.
-
-
-<p>
-A path is a string containing a sequence of
-<em>templates</em> separated by semicolons.
-For each template,
-the function replaces each interrogation mark (if any)
-in the template with a copy of <code>name</code>
-wherein all occurrences of <code>sep</code>
-(a dot, by default)
-were replaced by <code>rep</code>
-(the system's directory separator, by default),
-and then tries to open the resulting file name.
-
-
-<p>
-For instance, if the path is the string
-
-<pre>
-     "./?.lua;./?.lc;/usr/local/?/init.lua"
-</pre><p>
-the search for the name <code>foo.a</code>
-will try to open the files
-<code>./foo/a.lua</code>, <code>./foo/a.lc</code>, and
-<code>/usr/local/foo/a/init.lua</code>, in that order.
-
-
-<p>
-Returns the resulting name of the first file that it can
-open in read mode (after closing the file),
-or <b>nil</b> plus an error message if none succeeds.
-(This error message lists all file names it tried to open.)
-
-
-
-
-
-
-
-<h2>6.4 &ndash; <a name="6.4">String Manipulation</a></h2>
-
-<p>
-This library provides generic functions for string manipulation,
-such as finding and extracting substrings, and pattern matching.
-When indexing a string in Lua, the first character is at position&nbsp;1
-(not at&nbsp;0, as in C).
-Indices are allowed to be negative and are interpreted as indexing backwards,
-from the end of the string.
-Thus, the last character is at position -1, and so on.
-
-
-<p>
-The string library provides all its functions inside the table
-<a name="pdf-string"><code>string</code></a>.
-It also sets a metatable for strings
-where the <code>__index</code> field points to the <code>string</code> table.
-Therefore, you can use the string functions in object-oriented style.
-For instance, <code>string.byte(s,i)</code>
-can be written as <code>s:byte(i)</code>.
-
-
-<p>
-The string library assumes one-byte character encodings.
-
-
-<p>
-<hr><h3><a name="pdf-string.byte"><code>string.byte (s [, i [, j]])</code></a></h3>
-Returns the internal numerical codes of the characters <code>s[i]</code>,
-<code>s[i+1]</code>, ..., <code>s[j]</code>.
-The default value for <code>i</code> is&nbsp;1;
-the default value for <code>j</code> is&nbsp;<code>i</code>.
-These indices are corrected
-following the same rules of function <a href="#pdf-string.sub"><code>string.sub</code></a>.
-
-
-<p>
-Numerical codes are not necessarily portable across platforms.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.char"><code>string.char (&middot;&middot;&middot;)</code></a></h3>
-Receives zero or more integers.
-Returns a string with length equal to the number of arguments,
-in which each character has the internal numerical code equal
-to its corresponding argument.
-
-
-<p>
-Numerical codes are not necessarily portable across platforms.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.dump"><code>string.dump (function)</code></a></h3>
-
-
-<p>
-Returns a string containing a binary representation of the given function,
-so that a later <a href="#pdf-load"><code>load</code></a> on this string returns
-a copy of the function (but with new upvalues).
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.find"><code>string.find (s, pattern [, init [, plain]])</code></a></h3>
-
-
-<p>
-Looks for the first match of
-<code>pattern</code> in the string <code>s</code>.
-If it finds a match, then <code>find</code> returns the indices of&nbsp;<code>s</code>
-where this occurrence starts and ends;
-otherwise, it returns <b>nil</b>.
-A third, optional numerical argument <code>init</code> specifies
-where to start the search;
-its default value is&nbsp;1 and can be negative.
-A value of <b>true</b> as a fourth, optional argument <code>plain</code>
-turns off the pattern matching facilities,
-so the function does a plain "find substring" operation,
-with no characters in <code>pattern</code> being considered magic.
-Note that if <code>plain</code> is given, then <code>init</code> must be given as well.
-
-
-<p>
-If the pattern has captures,
-then in a successful match
-the captured values are also returned,
-after the two indices.
-
-
-

-<hr><h3><a name="pdf-string.format"><code>string.format (formatstring, &middot;&middot;&middot;)</code></a></h3>
-
-
-<p>
-Returns a formatted version of its variable number of arguments
-following the description given in its first argument (which must be a string).
-The format string follows the same rules as the ISO&nbsp;C function <code>sprintf</code>.
-The only differences are that the options/modifiers
-<code>*</code>, <code>h</code>, <code>L</code>, <code>l</code>, <code>n</code>,
-and <code>p</code> are not supported
-and that there is an extra option, <code>q</code>.
-The <code>q</code> option formats a string between double quotes,
-using escape sequences when necessary to ensure that
-it can safely be read back by the Lua interpreter.
-For instance, the call
-
-<pre>
-     string.format('%q', 'a string with "quotes" and \n new line')
-</pre><p>
-may produce the string:
-
-<pre>
-     "a string with \"quotes\" and \
-      new line"
-</pre>
-
-<p>
-Options
-<code>A</code> and <code>a</code> (when available),
-<code>E</code>, <code>e</code>, <code>f</code>,
-<code>G</code>, and <code>g</code> all expect a number as argument.
-Options <code>c</code>, <code>d</code>,
-<code>i</code>, <code>o</code>, <code>u</code>, <code>X</code>, and <code>x</code>
-also expect a number,
-but the range of that number may be limited by
-the underlying C&nbsp;implementation.
-For options <code>o</code>, <code>u</code>, <code>X</code>, and <code>x</code>,
-the number cannot be negative.
-Option <code>q</code> expects a string;
-option <code>s</code> expects a string without embedded zeros.
-If the argument to option <code>s</code> is not a string,
-it is converted to one following the same rules of <a href="#pdf-tostring"><code>tostring</code></a>.

-<hr><h3><a name="pdf-string.gmatch"><code>string.gmatch (s, pattern)</code></a></h3>
-Returns an iterator function that,
-each time it is called,
-returns the next captures from <code>pattern</code> over the string <code>s</code>.
-If <code>pattern</code> specifies no captures,
-then the whole match is produced in each call.
-
-
-<p>
-As an example, the following loop
-will iterate over all the words from string <code>s</code>,
-printing one per line:
-
-<pre>
-     s = "hello world from Lua"
-     for w in string.gmatch(s, "%a+") do
-       print(w)
-     end
-</pre><p>
-The next example collects all pairs <code>key=value</code> from the
-given string into a table:
-
-<pre>
-     t = {}
-     s = "from=world, to=Lua"
-     for k, v in string.gmatch(s, "(%w+)=(%w+)") do
-       t[k] = v
-     end
-</pre>
-
-<p>
-For this function, a caret '<code>^</code>' at the start of a pattern does not
-work as an anchor, as this would prevent the iteration.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.gsub"><code>string.gsub (s, pattern, repl [, n])</code></a></h3>
-Returns a copy of <code>s</code>
-in which all (or the first <code>n</code>, if given)
-occurrences of the <code>pattern</code> have been
-replaced by a replacement string specified by <code>repl</code>,
-which can be a string, a table, or a function.
-<code>gsub</code> also returns, as its second value,
-the total number of matches that occurred.
-The name <code>gsub</code> comes from <em>Global SUBstitution</em>.
-
-
-<p>
-If <code>repl</code> is a string, then its value is used for replacement.
-The character&nbsp;<code>%</code> works as an escape character:
-any sequence in <code>repl</code> of the form <code>%<em>d</em></code>,
-with <em>d</em> between 1 and 9,
-stands for the value of the <em>d</em>-th captured substring.
-The sequence <code>%0</code> stands for the whole match.
-The sequence <code>%%</code> stands for a single&nbsp;<code>%</code>.
-
-
-<p>
-If <code>repl</code> is a table, then the table is queried for every match,
-using the first capture as the key.
-
-
-<p>
-If <code>repl</code> is a function, then this function is called every time a
-match occurs, with all captured substrings passed as arguments,
-in order.
-
-
-<p>
-In any case,
-if the pattern specifies no captures,
-then it behaves as if the whole pattern was inside a capture.
-
-
-<p>
-If the value returned by the table query or by the function call
-is a string or a number,
-then it is used as the replacement string;
-otherwise, if it is <b>false</b> or <b>nil</b>,
-then there is no replacement
-(that is, the original match is kept in the string).
-
-
-<p>
-Here are some examples:
-
-<pre>
-     x = string.gsub("hello world", "(%w+)", "%1 %1")
-     --&gt; x="hello hello world world"
-     
-     x = string.gsub("hello world", "%w+", "%0 %0", 1)
-     --&gt; x="hello hello world"
-     
-     x = string.gsub("hello world from Lua", "(%w+)%s*(%w+)", "%2 %1")
-     --&gt; x="world hello Lua from"
-     
-     x = string.gsub("home = $HOME, user = $USER", "%$(%w+)", os.getenv)
-     --&gt; x="home = /home/roberto, user = roberto"
-     
-     x = string.gsub("4+5 = $return 4+5$", "%$(.-)%$", function (s)
-           return load(s)()
-         end)
-     --&gt; x="4+5 = 9"
-     
-     local t = {name="lua", version="5.2"}
-     x = string.gsub("$name-$version.tar.gz", "%$(%w+)", t)
-     --&gt; x="lua-5.2.tar.gz"

-<hr><h3><a name="pdf-string.len"><code>string.len (s)</code></a></h3>
-Receives a string and returns its length.
-The empty string <code>""</code> has length 0.
-Embedded zeros are counted,
-so <code>"a\000bc\000"</code> has length 5.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.lower"><code>string.lower (s)</code></a></h3>
-Receives a string and returns a copy of this string with all

-All other characters are left unchanged.
-The definition of what an uppercase letter is depends on the current locale.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.match"><code>string.match (s, pattern [, init])</code></a></h3>
-Looks for the first <em>match</em> of
-<code>pattern</code> in the string <code>s</code>.
-If it finds one, then <code>match</code> returns
-the captures from the pattern;
-otherwise it returns <b>nil</b>.
-If <code>pattern</code> specifies no captures,
-then the whole match is returned.
-A third, optional numerical argument <code>init</code> specifies
-where to start the search;
-its default value is&nbsp;1 and can be negative.
-

-<p>
-<hr><h3><a name="pdf-string.rep"><code>string.rep (s, n [, sep])</code></a></h3>
-Returns a string that is the concatenation of <code>n</code> copies of
-the string <code>s</code> separated by the string <code>sep</code>.
-The default value for <code>sep</code> is the empty string
-(that is, no separator).
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.reverse"><code>string.reverse (s)</code></a></h3>
-Returns a string that is the string <code>s</code> reversed.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.sub"><code>string.sub (s, i [, j])</code></a></h3>
-Returns the substring of <code>s</code> that
-starts at <code>i</code>  and continues until <code>j</code>;
-<code>i</code> and <code>j</code> can be negative.
-If <code>j</code> is absent, then it is assumed to be equal to -1
-(which is the same as the string length).
-In particular,
-the call <code>string.sub(s,1,j)</code> returns a prefix of <code>s</code>
-with length <code>j</code>,
-and <code>string.sub(s, -i)</code> returns a suffix of <code>s</code>
-with length <code>i</code>.
-
-
-<p>
-If, after the translation of negative indices,
-<code>i</code> is less than 1,
-it is corrected to 1.
-If <code>j</code> is greater than the string length,
-it is corrected to that length.
-If, after these corrections,
-<code>i</code> is greater than <code>j</code>,
-the function returns the empty string.
-

-The definition of what a lowercase letter is depends on the current locale.
-
-
-
-<h3>6.4.1 &ndash; <a name="6.4.1">Patterns</a></h3>
-
-
-<h4>Character Class:</h4><p>
-A <em>character class</em> is used to represent a set of characters.
-The following combinations are allowed in describing a character class:
-
-<ul>
-
-<li><b><em>x</em>: </b>
-(where <em>x</em> is not one of the <em>magic characters</em>
-<code>^$()%.[]*+-?</code>)
-represents the character <em>x</em> itself.
-</li>
-
-<li><b><code>.</code>: </b> (a dot) represents all characters.</li>
-
-<li><b><code>%a</code>: </b> represents all letters.</li>
-
-<li><b><code>%c</code>: </b> represents all control characters.</li>
-
-<li><b><code>%d</code>: </b> represents all digits.</li>
-
-<li><b><code>%g</code>: </b> represents all printable characters except space.</li>
-
-<li><b><code>%l</code>: </b> represents all lowercase letters.</li>
-
-<li><b><code>%p</code>: </b> represents all punctuation characters.</li>
-
-<li><b><code>%s</code>: </b> represents all space characters.</li>
-
-<li><b><code>%u</code>: </b> represents all uppercase letters.</li>
-
-<li><b><code>%w</code>: </b> represents all alphanumeric characters.</li>
-
-<li><b><code>%x</code>: </b> represents all hexadecimal digits.</li>
-
-<li><b><code>%<em>x</em></code>: </b> (where <em>x</em> is any non-alphanumeric character)
-represents the character <em>x</em>.
-This is the standard way to escape the magic characters.
-Any punctuation character (even the non magic)
-can be preceded by a '<code>%</code>'
-when used to represent itself in a pattern.
-</li>
-
-<li><b><code>[<em>set</em>]</code>: </b>
-represents the class which is the union of all
-characters in <em>set</em>.
-A range of characters can be specified by
-separating the end characters of the range,
-in ascending order, with a '<code>-</code>',
-All classes <code>%</code><em>x</em> described above can also be used as
-components in <em>set</em>.
-All other characters in <em>set</em> represent themselves.
-For example, <code>[%w_]</code> (or <code>[_%w]</code>)
-represents all alphanumeric characters plus the underscore,
-<code>[0-7]</code> represents the octal digits,
-and <code>[0-7%l%-]</code> represents the octal digits plus
-the lowercase letters plus the '<code>-</code>' character.
-
-
-<p>
-The interaction between ranges and classes is not defined.
-Therefore, patterns like <code>[%a-z]</code> or <code>[a-%%]</code>
-have no meaning.
-</li>
-
-<li><b><code>[^<em>set</em>]</code>: </b>
-represents the complement of <em>set</em>,
-where <em>set</em> is interpreted as above.
-</li>
-
-</ul><p>
-For all classes represented by single letters (<code>%a</code>, <code>%c</code>, etc.),
-the corresponding uppercase letter represents the complement of the class.
-For instance, <code>%S</code> represents all non-space characters.
-
-
-<p>
-The definitions of letter, space, and other character groups
-depend on the current locale.
-In particular, the class <code>[a-z]</code> may not be equivalent to <code>%l</code>.
-
-
-
-
-
-<h4>Pattern Item:</h4><p>
-A <em>pattern item</em> can be
-
-<ul>
-
-<li>
-a single character class,
-which matches any single character in the class;
-</li>
-
-<li>
-a single character class followed by '<code>*</code>',
-which matches 0 or more repetitions of characters in the class.
-These repetition items will always match the longest possible sequence;
-</li>
-
-<li>
-a single character class followed by '<code>+</code>',
-which matches 1 or more repetitions of characters in the class.
-These repetition items will always match the longest possible sequence;
-</li>
-
-<li>
-a single character class followed by '<code>-</code>',
-which also matches 0 or more repetitions of characters in the class.
-Unlike '<code>*</code>',
-these repetition items will always match the shortest possible sequence;
-</li>
-
-<li>
-a single character class followed by '<code>?</code>',
-which matches 0 or 1 occurrence of a character in the class;
-</li>
-
-<li>
-<code>%<em>n</em></code>, for <em>n</em> between 1 and 9;
-such item matches a substring equal to the <em>n</em>-th captured string
-(see below);
-</li>
-
-<li>
-<code>%b<em>xy</em></code>, where <em>x</em> and <em>y</em> are two distinct characters;
-such item matches strings that start with&nbsp;<em>x</em>, end with&nbsp;<em>y</em>,
-and where the <em>x</em> and <em>y</em> are <em>balanced</em>.
-This means that, if one reads the string from left to right,
-counting <em>+1</em> for an <em>x</em> and <em>-1</em> for a <em>y</em>,
-the ending <em>y</em> is the first <em>y</em> where the count reaches 0.
-For instance, the item <code>%b()</code> matches expressions with
-balanced parentheses.
-</li>
-
-<li>
-<code>%f[<em>set</em>]</code>, a <em>frontier pattern</em>;
-such item matches an empty string at any position such that
-the next character belongs to <em>set</em>
-and the previous character does not belong to <em>set</em>.
-The set <em>set</em> is interpreted as previously described.
-The beginning and the end of the subject are handled as if
-they were the character '<code>\0</code>'.
-</li>
-
-</ul>
-
-
-
-
-<h4>Pattern:</h4><p>
-A <em>pattern</em> is a sequence of pattern items.
-A caret '<code>^</code>' at the beginning of a pattern anchors the match at the
-beginning of the subject string.
-A '<code>$</code>' at the end of a pattern anchors the match at the
-end of the subject string.
-At other positions,
-'<code>^</code>' and '<code>$</code>' have no special meaning and represent themselves.
-
-
-
-
-
-<h4>Captures:</h4><p>
-A pattern can contain sub-patterns enclosed in parentheses;
-they describe <em>captures</em>.
-When a match succeeds, the substrings of the subject string
-that match captures are stored (<em>captured</em>) for future use.
-Captures are numbered according to their left parentheses.
-For instance, in the pattern <code>"(a*(.)%w(%s*))"</code>,
-the part of the string matching <code>"a*(.)%w(%s*)"</code> is
-stored as the first capture (and therefore has number&nbsp;1);
-the character matching "<code>.</code>" is captured with number&nbsp;2,
-and the part matching "<code>%s*</code>" has number&nbsp;3.
-
-
-<p>
-As a special case, the empty capture <code>()</code> captures
-the current string position (a number).
-For instance, if we apply the pattern <code>"()aa()"</code> on the
-string <code>"flaaap"</code>, there will be two captures: 3&nbsp;and&nbsp;5.

-<h2>6.5 &ndash; <a name="6.5">Table Manipulation</a></h2>
-
-<p>
-This library provides generic functions for table manipulation.
-It provides all its functions inside the table <a name="pdf-table"><code>table</code></a>.
-
-
-<p>
-Remember that, whenever an operation needs the length of a table,
-the table should be a proper sequence
-or have a <code>__len</code> metamethod (see <a href="#3.4.6">&sect;3.4.6</a>).
-All functions ignore non-numeric keys
-in tables given as arguments.
-
-
-<p>
-For performance reasons,
-all table accesses (get/set) performed by these functions are raw.
-
-
-<p>
-<hr><h3><a name="pdf-table.concat"><code>table.concat (list [, sep [, i [, j]]])</code></a></h3>
-
-
-<p>
-Given a list where all elements are strings or numbers,
-returns the string <code>list[i]..sep..list[i+1] &middot;&middot;&middot; sep..list[j]</code>.
-The default value for <code>sep</code> is the empty string,
-the default for <code>i</code> is 1,
-and the default for <code>j</code> is <code>#list</code>.
-If <code>i</code> is greater than <code>j</code>, returns the empty string.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-table.insert"><code>table.insert (list, [pos,] value)</code></a></h3>
-
-
-<p>
-Inserts element <code>value</code> at position <code>pos</code> in <code>list</code>,
-shifting up the elements
-<code>list[pos], list[pos+1], &middot;&middot;&middot;, list[#list]</code>.
-The default value for <code>pos</code> is <code>#list+1</code>,
-so that a call <code>table.insert(t,x)</code> inserts <code>x</code> at the end
-of list <code>t</code>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-table.pack"><code>table.pack (&middot;&middot;&middot;)</code></a></h3>
-
-
-<p>
-Returns a new table with all parameters stored into keys 1, 2, etc.
-and with a field "<code>n</code>" with the total number of parameters.
-Note that the resulting table may not be a sequence.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-table.remove"><code>table.remove (list [, pos])</code></a></h3>
-
-
-<p>
-Removes from <code>list</code> the element at position <code>pos</code>,
-returning the value of the removed element.
-When <code>pos</code> is an integer between 1 and <code>#list</code>,
-it shifts down the elements
-<code>list[pos+1], list[pos+2], &middot;&middot;&middot;, list[#list]</code>
-and erases element <code>list[#list]</code>;
-The index <code>pos</code> can also be 0 when <code>#list</code> is 0,
-or <code>#list + 1</code>;
-in those cases, the function erases the element <code>list[pos]</code>.
-
-
-<p>
-The default value for <code>pos</code> is <code>#list</code>,
-so that a call <code>table.remove(t)</code> removes the last element
-of list <code>t</code>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-table.sort"><code>table.sort (list [, comp])</code></a></h3>
-
-
-<p>
-Sorts list elements in a given order, <em>in-place</em>,
-from <code>list[1]</code> to <code>list[#list]</code>.
-If <code>comp</code> is given,
-then it must be a function that receives two list elements
-and returns true when the first element must come
-before the second in the final order
-(so that <code>not comp(list[i+1],list[i])</code> will be true after the sort).
-If <code>comp</code> is not given,
-then the standard Lua operator <code>&lt;</code> is used instead.
-
-
-<p>
-The sort algorithm is not stable;
-that is, elements considered equal by the given order
-may have their relative positions changed by the sort.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-table.unpack"><code>table.unpack (list [, i [, j]])</code></a></h3>
-
-
-<p>
-Returns the elements from the given table.
-This function is equivalent to
-
-<pre>
-     return list[i], list[i+1], &middot;&middot;&middot;, list[j]
-</pre><p>
-By default, <code>i</code> is&nbsp;1 and <code>j</code> is <code>#list</code>.

-each argument is normalized to
-the remainder of its division by <em>2<sup>32</sup></em>
-and truncated to an integer (in some unspecified way),

-<h2>6.8 &ndash; <a name="6.8">Input and Output Facilities</a></h2>
-
-<p>
-The I/O library provides two different styles for file manipulation.
-The first one uses implicit file descriptors;
-that is, there are operations to set a default input file and a
-default output file,
-and all input/output operations are over these default files.
-The second style uses explicit file descriptors.
-
-
-<p>
-When using implicit file descriptors,
-all operations are supplied by table <a name="pdf-io"><code>io</code></a>.
-When using explicit file descriptors,
-the operation <a href="#pdf-io.open"><code>io.open</code></a> returns a file descriptor
-and then all operations are supplied as methods of the file descriptor.
-
-
-<p>
-The table <code>io</code> also provides
-three predefined file descriptors with their usual meanings from C:
-<a name="pdf-io.stdin"><code>io.stdin</code></a>, <a name="pdf-io.stdout"><code>io.stdout</code></a>, and <a name="pdf-io.stderr"><code>io.stderr</code></a>.
-The I/O library never closes these files.
-
-
-<p>
-Unless otherwise stated,
-all I/O functions return <b>nil</b> on failure
-(plus an error message as a second result and
-a system-dependent error code as a third result)
-and some value different from <b>nil</b> on success.
-On non-Posix systems,
-the computation of the error message and error code
-in case of errors
-may be not thread safe,
-because they rely on the global C variable <code>errno</code>.
-
-
-<p>
-<hr><h3><a name="pdf-io.close"><code>io.close ([file])</code></a></h3>
-
-
-<p>
-Equivalent to <code>file:close()</code>.
-Without a <code>file</code>, closes the default output file.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-io.flush"><code>io.flush ()</code></a></h3>
-
-
-<p>
-Equivalent to <code>io.output():flush()</code>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-io.input"><code>io.input ([file])</code></a></h3>
-
-
-<p>
-When called with a file name, it opens the named file (in text mode),
-and sets its handle as the default input file.
-When called with a file handle,
-it simply sets this file handle as the default input file.
-When called without parameters,
-it returns the current default input file.
-
-
-<p>
-In case of errors this function raises the error,
-instead of returning an error code.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-io.lines"><code>io.lines ([filename &middot;&middot;&middot;])</code></a></h3>
-
-
-<p>
-Opens the given file name in read mode
-and returns an iterator function that
-works like <code>file:lines(&middot;&middot;&middot;)</code> over the opened file.
-When the iterator function detects the end of file,
-it returns <b>nil</b> (to finish the loop) and automatically closes the file.
-
-
-<p>
-The call <code>io.lines()</code> (with no file name) is equivalent
-to <code>io.input():lines()</code>;
-that is, it iterates over the lines of the default input file.
-In this case it does not close the file when the loop ends.
-
-
-<p>
-In case of errors this function raises the error,
-instead of returning an error code.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-io.open"><code>io.open (filename [, mode])</code></a></h3>
-
-
-<p>
-This function opens a file,
-in the mode specified in the string <code>mode</code>.
-It returns a new file handle,
-or, in case of errors, <b>nil</b> plus an error message.
-
-
-<p>
-The <code>mode</code> string can be any of the following:
-
-<ul>
-<li><b>"<code>r</code>": </b> read mode (the default);</li>
-<li><b>"<code>w</code>": </b> write mode;</li>
-<li><b>"<code>a</code>": </b> append mode;</li>
-<li><b>"<code>r+</code>": </b> update mode, all previous data is preserved;</li>
-<li><b>"<code>w+</code>": </b> update mode, all previous data is erased;</li>
-<li><b>"<code>a+</code>": </b> append update mode, previous data is preserved,
-  writing is only allowed at the end of file.</li>
-</ul><p>
-The <code>mode</code> string can also have a '<code>b</code>' at the end,
-which is needed in some systems to open the file in binary mode.
-

-<hr><h3><a name="pdf-io.output"><code>io.output ([file])</code></a></h3>
-
-

-
-
-
-<p>
-<hr><h3><a name="pdf-io.popen"><code>io.popen (prog [, mode])</code></a></h3>
-
-
-<p>
-This function is system dependent and is not available
-on all platforms.
-
-
-<p>
-Starts program <code>prog</code> in a separated process and returns
-a file handle that you can use to read data from this program
-(if <code>mode</code> is <code>"r"</code>, the default)
-or to write data to this program
-(if <code>mode</code> is <code>"w"</code>).

-
-
-
-
-<p>
-<hr><h3><a name="pdf-io.type"><code>io.type (obj)</code></a></h3>
-
-
-<p>
-Checks whether <code>obj</code> is a valid file handle.
-Returns the string <code>"file"</code> if <code>obj</code> is an open file handle,
-<code>"closed file"</code> if <code>obj</code> is a closed file handle,
-or <b>nil</b> if <code>obj</code> is not a file handle.

-
-
-<p>
-<hr><h3><a name="pdf-file:close"><code>file:close ()</code></a></h3>
-
-
-<p>
-Closes <code>file</code>.
-Note that files are automatically closed when
-their handles are garbage collected,
-but that takes an unpredictable amount of time to happen.
-
-
-<p>
-When closing a file handle created with <a href="#pdf-io.popen"><code>io.popen</code></a>,
-<a href="#pdf-file:close"><code>file:close</code></a> returns the same values
-returned by <a href="#pdf-os.execute"><code>os.execute</code></a>.

-
-
-
-
-<p>
-<hr><h3><a name="pdf-file:lines"><code>file:lines (&middot;&middot;&middot;)</code></a></h3>
-
-
-<p>
-Returns an iterator function that,
-each time it is called,
-reads the file according to the given formats.
-When no format is given,
-uses "*l" as a default.
-As an example, the construction
-
-<pre>
-     for c in file:lines(1) do <em>body</em> end
-</pre><p>
-will iterate over all characters of the file,
-starting at the current position.
-Unlike <a href="#pdf-io.lines"><code>io.lines</code></a>, this function does not close the file
-when the loop ends.
-
-
-<p>
-In case of errors this function raises the error,
-instead of returning an error code.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-file:read"><code>file:read (&middot;&middot;&middot;)</code></a></h3>
-
-
-<p>
-Reads the file <code>file</code>,
-according to the given formats, which specify what to read.
-For each format,
-the function returns a string (or a number) with the characters read,
-or <b>nil</b> if it cannot read data with the specified format.
-When called without formats,
-it uses a default format that reads the next line
-(see below).
-
-
-<p>
-The available formats are
-
-<ul>
-
-<li><b>"<code>*n</code>": </b>
-reads a number;
-this is the only format that returns a number instead of a string.
-</li>
-
-<li><b>"<code>*a</code>": </b>
-reads the whole file, starting at the current position.
-On end of file, it returns the empty string.
-</li>
-
-<li><b>"<code>*l</code>": </b>
-reads the next line skipping the end of line,
-returning <b>nil</b> on end of file.
-This is the default format.
-</li>
-
-<li><b>"<code>*L</code>": </b>
-reads the next line keeping the end of line (if present),
-returning <b>nil</b> on end of file.
-</li>
-
-<li><b><em>number</em>: </b>
-reads a string with up to this number of bytes,
-returning <b>nil</b> on end of file.
-If number is zero,
-it reads nothing and returns an empty string,
-or <b>nil</b> on end of file.
-</li>
-
-</ul>
-
-
-
-<p>
-<hr><h3><a name="pdf-file:seek"><code>file:seek ([whence [, offset]])</code></a></h3>
-
-
-<p>
-Sets and gets the file position,
-measured from the beginning of the file,
-to the position given by <code>offset</code> plus a base
-specified by the string <code>whence</code>, as follows:
-
-<ul>
-<li><b>"<code>set</code>": </b> base is position 0 (beginning of the file);</li>
-<li><b>"<code>cur</code>": </b> base is current position;</li>
-<li><b>"<code>end</code>": </b> base is end of file;</li>
-</ul><p>
-In case of success, <code>seek</code> returns the final file position,
-measured in bytes from the beginning of the file.
-If <code>seek</code> fails, it returns <b>nil</b>,
-plus a string describing the error.
-
-
-<p>
-The default value for <code>whence</code> is <code>"cur"</code>,
-and for <code>offset</code> is 0.
-Therefore, the call <code>file:seek()</code> returns the current
-file position, without changing it;
-the call <code>file:seek("set")</code> sets the position to the
-beginning of the file (and returns 0);
-and the call <code>file:seek("end")</code> sets the position to the
-end of the file, and returns its size.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-file:setvbuf"><code>file:setvbuf (mode [, size])</code></a></h3>
-
-
-<p>
-Sets the buffering mode for an output file.
-There are three available modes:
-
-<ul>
-
-<li><b>"<code>no</code>": </b>
-no buffering; the result of any output operation appears immediately.
-</li>
-
-<li><b>"<code>full</code>": </b>
-full buffering; output operation is performed only
-when the buffer is full or when
-you explicitly <code>flush</code> the file (see <a href="#pdf-io.flush"><code>io.flush</code></a>).
-</li>
-
-<li><b>"<code>line</code>": </b>
-line buffering; output is buffered until a newline is output
-or there is any input from some special files
-(such as a terminal device).
-</li>
-
-</ul><p>
-For the last two cases, <code>size</code>
-specifies the size of the buffer, in bytes.
-The default is an appropriate size.

-<hr><h3><a name="pdf-os.date"><code>os.date ([format [, time]])</code></a></h3>
-
-
-<p>
-Returns a string or a table containing date and time,

-
-
-<p>
-If the <code>time</code> argument is present,
-this is the time to be formatted
-(see the <a href="#pdf-os.time"><code>os.time</code></a> function for a description of this value).
-Otherwise, <code>date</code> formats the current time.
-

-<p>
-If <code>format</code> starts with '<code>!</code>',
-then the date is formatted in Coordinated Universal Time.
-After this optional character,
-if <code>format</code> is the string "<code>*t</code>",

-This last field may be absent
-if the information is not available.
-

-If <code>code</code> is <b>true</b>,
-the returned status is <code>EXIT_SUCCESS</code>;
-if <code>code</code> is <b>false</b>,
-the returned status is <code>EXIT_FAILURE</code>;
-if <code>code</code> is a number,
-the returned status is this number.
-The default value for <code>code</code> is <b>true</b>.
-
-

-<p>
-<hr><h3><a name="pdf-os.setlocale"><code>os.setlocale (locale [, category])</code></a></h3>
-
-
-<p>
-Sets the current locale of the program.
-<code>locale</code> is a system-dependent string specifying a locale;
-<code>category</code> is an optional string describing which category to change:
-<code>"all"</code>, <code>"collate"</code>, <code>"ctype"</code>,
-<code>"monetary"</code>, <code>"numeric"</code>, or <code>"time"</code>;
-the default category is <code>"all"</code>.
-The function returns the name of the new locale,
-or <b>nil</b> if the request cannot be honored.
-
-
-<p>
-If <code>locale</code> is the empty string,
-the current locale is set to an implementation-defined native locale.
-If <code>locale</code> is the string "<code>C</code>",
-the current locale is set to the standard C locale.
-
-
-<p>
-When called with <b>nil</b> as the first argument,
-this function only returns the name of the current locale
-for the given category.
-
-
-<p>
-This function may be not thread safe
-because of its reliance on C&nbsp;function <code>setlocale</code>.

-<hr><h3><a name="pdf-os.time"><code>os.time ([table])</code></a></h3>
-
-
-<p>
-Returns the current time when called without arguments,
-or a time representing the date and time specified by the given table.
-This table must have fields <code>year</code>, <code>month</code>, and <code>day</code>,
-and may have fields
-<code>hour</code> (default is 12),
-<code>min</code> (default is 0),
-<code>sec</code> (default is 0),
-and <code>isdst</code> (default is <b>nil</b>).
-For a description of these fields, see the <a href="#pdf-os.date"><code>os.date</code></a> function.
-
-
-<p>
-The returned value is a number, whose meaning depends on your system.
-In POSIX, Windows, and some other systems,
-this number counts the number
-of seconds since some given start time (the "epoch").
-In other systems, the meaning is not specified,
-and the number returned by <code>time</code> can be used only as an argument to
-<a href="#pdf-os.date"><code>os.date</code></a> and <a href="#pdf-os.difftime"><code>os.difftime</code></a>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-os.tmpname"><code>os.tmpname ()</code></a></h3>
-
-
-<p>
-Returns a string with a file name that can
-be used for a temporary file.
-The file must be explicitly opened before its use
-and explicitly removed when no longer needed.
-
-
-<p>
-On POSIX systems,
-this function also creates a file with that name,
-to avoid security risks.
-(Someone else might create the file with wrong permissions
-in the time between getting the name and creating the file.)
-You still have to open the file to use it
-and to remove it (even if you do not use it).
-
-
-<p>
-When possible,
-you may prefer to use <a href="#pdf-io.tmpfile"><code>io.tmpfile</code></a>,
-which automatically removes the file when the program ends.

-<h2>6.10 &ndash; <a name="6.10">The Debug Library</a></h2>
-
-<p>
-This library provides
-the functionality of the debug interface (<a href="#4.9">&sect;4.9</a>) to Lua programs.
-You should exert care when using this library.
-Several of its functions
-violate basic assumptions about Lua code
-(e.g., that variables local to a function
-cannot be accessed from outside;
-that userdata metatables cannot be changed by Lua code;
-that Lua programs do not crash)
-and therefore can compromise otherwise secure code.
-Moreover, some functions in this library may be slow.
-
-
-<p>
-All functions in this library are provided
-inside the <a name="pdf-debug"><code>debug</code></a> table.
-All functions that operate over a thread
-have an optional first argument which is the
-thread to operate over.
-The default is always the current thread.
-
-
-<p>
-<hr><h3><a name="pdf-debug.debug"><code>debug.debug ()</code></a></h3>
-
-
-<p>
-Enters an interactive mode with the user,
-running each string that the user enters.
-Using simple commands and other debug facilities,
-the user can inspect global and local variables,
-change their values, evaluate expressions, and so on.
-A line containing only the word <code>cont</code> finishes this function,
-so that the caller continues its execution.
-
-
-<p>
-Note that commands for <code>debug.debug</code> are not lexically nested
-within any function and so have no direct access to local variables.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-debug.gethook"><code>debug.gethook ([thread])</code></a></h3>
-
-
-<p>
-Returns the current hook settings of the thread, as three values:
-the current hook function, the current hook mask,
-and the current hook count
-(as set by the <a href="#pdf-debug.sethook"><code>debug.sethook</code></a> function).
-
-
-
-
-<p>
-<hr><h3><a name="pdf-debug.getinfo"><code>debug.getinfo ([thread,] f [, what])</code></a></h3>
-
-
-<p>
-Returns a table with information about a function.
-You can give the function directly
-or you can give a number as the value of <code>f</code>,
-which means the function running at level <code>f</code> of the call stack
-of the given thread:
-level&nbsp;0 is the current function (<code>getinfo</code> itself);
-level&nbsp;1 is the function that called <code>getinfo</code>
-(except for tail calls, which do not count on the stack);
-and so on.
-If <code>f</code> is a number larger than the number of active functions,
-then <code>getinfo</code> returns <b>nil</b>.
-
-
-<p>
-The returned table can contain all the fields returned by <a href="#lua_getinfo"><code>lua_getinfo</code></a>,
-with the string <code>what</code> describing which fields to fill in.
-The default for <code>what</code> is to get all information available,
-except the table of valid lines.
-If present,
-the option '<code>f</code>'
-adds a field named <code>func</code> with the function itself.
-If present,
-the option '<code>L</code>'
-adds a field named <code>activelines</code> with the table of
-valid lines.
-
-
-<p>
-For instance, the expression <code>debug.getinfo(1,"n").name</code> returns
-a table with a name for the current function,
-if a reasonable name can be found,
-and the expression <code>debug.getinfo(print)</code>
-returns a table with all available information
-about the <a href="#pdf-print"><code>print</code></a> function.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-debug.getlocal"><code>debug.getlocal ([thread,] f, local)</code></a></h3>
-
-
-<p>
-This function returns the name and the value of the local variable
-with index <code>local</code> of the function at level <code>f</code> of the stack.
-This function accesses not only explicit local variables,
-but also parameters, temporaries, etc.
-
-
-<p>
-The first parameter or local variable has index&nbsp;1, and so on,
-until the last active variable.
-Negative indices refer to vararg parameters;
--1 is the first vararg parameter.
-The function returns <b>nil</b> if there is no variable with the given index,
-and raises an error when called with a level out of range.
-(You can call <a href="#pdf-debug.getinfo"><code>debug.getinfo</code></a> to check whether the level is valid.)
-
-
-<p>
-Variable names starting with '<code>(</code>' (open parenthesis)
-represent internal variables
-(loop control variables, temporaries, varargs, and C&nbsp;function locals).
-
-
-<p>
-The parameter <code>f</code> may also be a function.
-In that case, <code>getlocal</code> returns only the name of function parameters.

-
-
-
-<p>
-<hr><h3><a name="pdf-debug.getuservalue"><code>debug.getuservalue (u)</code></a></h3>
-
-
-<p>
-Returns the Lua value associated to <code>u</code>.
-If <code>u</code> is not a userdata,
-returns <b>nil</b>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-debug.sethook"><code>debug.sethook ([thread,] hook, mask [, count])</code></a></h3>
-
-
-<p>
-Sets the given function as a hook.
-The string <code>mask</code> and the number <code>count</code> describe
-when the hook will be called.
-The string mask may have any combination of the following characters,
-with the given meaning:
-
-<ul>
-<li><b>'<code>c</code>': </b> the hook is called every time Lua calls a function;</li>
-<li><b>'<code>r</code>': </b> the hook is called every time Lua returns from a function;</li>
-<li><b>'<code>l</code>': </b> the hook is called every time Lua enters a new line of code.</li>
-</ul><p>
-Moreover,
-with a <code>count</code> different from zero,
-the hook is called also after every <code>count</code> instructions.
-
-
-<p>
-When called without arguments,
-<a href="#pdf-debug.sethook"><code>debug.sethook</code></a> turns off the hook.
-
-
-<p>
-When the hook is called, its first parameter is a string
-describing the event that has triggered its call:
-<code>"call"</code> (or <code>"tail call"</code>),
-<code>"return"</code>,
-<code>"line"</code>, and <code>"count"</code>.
-For line events,
-the hook also gets the new line number as its second parameter.
-Inside a hook,
-you can call <code>getinfo</code> with level&nbsp;2 to get more information about
-the running function
-(level&nbsp;0 is the <code>getinfo</code> function,
-and level&nbsp;1 is the hook function).
-
-

-<hr><h3><a name="pdf-debug.setlocal"><code>debug.setlocal ([thread,] level, local, value)</code></a></h3>
-
-
-<p>
-This function assigns the value <code>value</code> to the local variable
-with index <code>local</code> of the function at level <code>level</code> of the stack.
-The function returns <b>nil</b> if there is no local

-Returns an unique identifier (as a light userdata)
-for the upvalue numbered <code>n</code>
-from the given function.
-
-
-<p>
-These unique identifiers allow a program to check whether different

-
-<h1>7 &ndash; <a name="7">Lua Standalone</a></h1>
-
-<p>
-Although Lua has been designed as an extension language,
-to be embedded in a host C&nbsp;program,
-it is also frequently used as a standalone language.
-An interpreter for Lua as a standalone language,
-called simply <code>lua</code>,
-is provided with the standard distribution.
-The standalone interpreter includes
-all standard libraries, including the debug library.
-Its usage is:
-
-<pre>
-     lua [options] [script [args]]
-</pre><p>
-The options are:
-
-<ul>
-<li><b><code>-e <em>stat</em></code>: </b> executes string <em>stat</em>;</li>
-<li><b><code>-l <em>mod</em></code>: </b> "requires" <em>mod</em>;</li>
-<li><b><code>-i</code>: </b> enters interactive mode after running <em>script</em>;</li>
-<li><b><code>-v</code>: </b> prints version information;</li>
-<li><b><code>-E</code>: </b> ignores environment variables;</li>
-<li><b><code>--</code>: </b> stops handling options;</li>
-<li><b><code>-</code>: </b> executes <code>stdin</code> as a file and stops handling options.</li>
-</ul><p>
-After handling its options, <code>lua</code> runs the given <em>script</em>,
-passing to it the given <em>args</em> as string arguments.
-When called without arguments,
-<code>lua</code> behaves as <code>lua -v -i</code>
-when the standard input (<code>stdin</code>) is a terminal,
-and as <code>lua -</code> otherwise.
-
-
-<p>
-When called without option <code>-E</code>, 
-the interpreter checks for an environment variable <a name="pdf-LUA_INIT_5_2"><code>LUA_INIT_5_2</code></a>
-(or <a name="pdf-LUA_INIT"><code>LUA_INIT</code></a> if it is not defined)
-before running any argument.
-If the variable content has the format <code>@<em>filename</em></code>,
-then <code>lua</code> executes the file.
-Otherwise, <code>lua</code> executes the string itself.
-
-
-<p>
-When called with option <code>-E</code>,
-besides ignoring <code>LUA_INIT</code>,
-Lua also ignores
-the values of <code>LUA_PATH</code> and <code>LUA_CPATH</code>,
-setting the values of
-<a href="#pdf-package.path"><code>package.path</code></a> and <a href="#pdf-package.cpath"><code>package.cpath</code></a>
-with the default paths defined in <code>luaconf.h</code>.
-
-
-<p>
-All options are handled in order, except <code>-i</code> and <code>-E</code>.
-For instance, an invocation like
-
-<pre>
-     $ lua -e'a=1' -e 'print(a)' script.lua
-</pre><p>
-will first set <code>a</code> to 1, then print the value of <code>a</code>,
-and finally run the file <code>script.lua</code> with no arguments.
-(Here <code>$</code> is the shell prompt. Your prompt may be different.)
-
-
-<p>
-Before starting to run the script,
-<code>lua</code> collects all arguments in the command line
-in a global table called <code>arg</code>.
-The script name is stored at index 0,
-the first argument after the script name goes to index 1,
-and so on.
-Any arguments before the script name
-(that is, the interpreter name plus the options)
-go to negative indices.
-For instance, in the call
-
-<pre>
-     $ lua -la b.lua t1 t2
-</pre><p>
-the interpreter first runs the file <code>a.lua</code>,
-then creates a table
-
-<pre>
-     arg = { [-2] = "lua", [-1] = "-la",
-             [0] = "b.lua",
-             [1] = "t1", [2] = "t2" }
-</pre><p>
-and finally runs the file <code>b.lua</code>.
-The script is called with <code>arg[1]</code>, <code>arg[2]</code>, ...
-as arguments;
-it can also access these arguments with the vararg expression '<code>...</code>'.
-
-
-<p>
-In interactive mode,
-if you write an incomplete statement,
-the interpreter waits for its completion
-by issuing a different prompt.
-
-
-<p>
-In case of unprotected errors in the script,
-the interpreter reports the error to the standard error stream.
-If the error object is a string,
-the interpreter adds a stack traceback to it.
-Otherwise, if the error object has a metamethod <code>__tostring</code>,
-the interpreter calls this metamethod to produce the final message.
-Finally, if the error object is <b>nil</b>,
-the interpreter does not report the error.
-
-
-<p>
-When finishing normally,
-the interpreter closes its main Lua state
-(see <a href="#lua_close"><code>lua_close</code></a>).
-The script can avoid this step by
-calling <a href="#pdf-os.exit"><code>os.exit</code></a> to terminate.
-
-
-<p>
-To allow the use of Lua as a
-script interpreter in Unix systems,
-the standalone interpreter skips
-the first line of a chunk if it starts with <code>#</code>.
-Therefore, Lua scripts can be made into executable programs
-by using <code>chmod +x</code> and the&nbsp;<code>#!</code> form,
-as in
-
-<pre>
-     #!/usr/local/bin/lua
-</pre><p>
-(Of course,
-the location of the Lua interpreter may be different in your machine.
-If <code>lua</code> is in your <code>PATH</code>,
-then
-
-<pre>
-     #!/usr/bin/env lua
-</pre><p>
-is a more portable solution.)

-<h1>8 &ndash; <a name="8">Incompatibilities with the Previous Version</a></h1>
-
-<p>
-Here we list the incompatibilities that you may find when moving a program
-from Lua&nbsp;5.1 to Lua&nbsp;5.2.
-You can avoid some incompatibilities by compiling Lua with
-appropriate options (see file <code>luaconf.h</code>).
-However,
-all these compatibility options will be removed in the next version of Lua.
-Similarly,
-all features marked as deprecated in Lua&nbsp;5.1
-have been removed in Lua&nbsp;5.2.
-
-
-
-<h2>8.1 &ndash; <a name="8.1">Changes in the Language</a></h2>
-<ul>
-
-<li>
-The concept of <em>environment</em> changed.
-Only Lua functions have environments.
-To set the environment of a Lua function,
-use the variable <code>_ENV</code> or the function <a href="#pdf-load"><code>load</code></a>.
-
-
-<p>
-C functions no longer have environments.
-Use an upvalue with a shared table if you need to keep
-shared state among several C functions.
-(You may use <a href="#luaL_setfuncs"><code>luaL_setfuncs</code></a> to open a C library
-with all functions sharing a common upvalue.)
-
-
-<p>
-To manipulate the "environment" of a userdata
-(which is now called user value),
-use the new functions
-<a href="#lua_getuservalue"><code>lua_getuservalue</code></a> and <a href="#lua_setuservalue"><code>lua_setuservalue</code></a>.
-</li>
-
-<li>
-Lua identifiers cannot use locale-dependent letters.
-</li>
-
-<li>
-Doing a step or a full collection in the garbage collector
-does not restart the collector if it has been stopped.
-</li>
-
-<li>
-Weak tables with weak keys now perform like <em>ephemeron tables</em>.
-</li>
-
-<li>
-The event <em>tail return</em> in debug hooks was removed.
-Instead, tail calls generate a special new event,
-<em>tail call</em>, so that the debugger can know that
-there will not be a corresponding return event.
-</li>
-
-<li>
-Equality between function values has changed.
-Now, a function definition may not create a new value;
-it may reuse some previous value if there is no
-observable difference to the new function.
-</li>
-
-</ul>
-
-
-
-
-<h2>8.2 &ndash; <a name="8.2">Changes in the Libraries</a></h2>
-<ul>
-
-<li>
-Function <code>module</code> is deprecated.
-It is easy to set up a module with regular Lua code.
-Modules are not expected to set global variables.
-</li>
-
-<li>
-Functions <code>setfenv</code> and <code>getfenv</code> were removed,
-because of the changes in environments.
-</li>
-
-<li>
-Function <code>math.log10</code> is deprecated.
-Use <a href="#pdf-math.log"><code>math.log</code></a> with 10 as its second argument, instead.
-</li>
-
-<li>
-Function <code>loadstring</code> is deprecated.
-Use <code>load</code> instead; it now accepts string arguments
-and are exactly equivalent to <code>loadstring</code>.
-</li>
-
-<li>
-Function <code>table.maxn</code> is deprecated.
-Write it in Lua if you really need it.
-</li>
-
-<li>
-Function <code>os.execute</code> now returns <b>true</b> when command
-terminates successfully and <b>nil</b> plus error information
-otherwise.
-</li>
-
-<li>
-Function <code>unpack</code> was moved into the table library
-and therefore must be called as <a href="#pdf-table.unpack"><code>table.unpack</code></a>.
-</li>
-
-<li>
-Character class <code>%z</code> in patterns is deprecated,
-as now patterns may contain '<code>\0</code>' as a regular character.
-</li>
-
-<li>
-The table <code>package.loaders</code> was renamed <code>package.searchers</code>.
-</li>
-
-<li>
-Lua does not have bytecode verification anymore.
-So, all functions that load code
-(<a href="#pdf-load"><code>load</code></a> and <a href="#pdf-loadfile"><code>loadfile</code></a>)
-are potentially insecure when loading untrusted binary data.
-(Actually, those functions were already insecure because
-of flaws in the verification algorithm.)
-When in doubt,
-use the <code>mode</code> argument of those functions
-to restrict them to loading textual chunks.
-</li>
-
-<li>
-The standard paths in the official distribution may
-change between versions.
-</li>
-
-</ul>
-
-
-
-
-<h2>8.3 &ndash; <a name="8.3">Changes in the API</a></h2>
-<ul>
-
-<li>
-Pseudoindex <code>LUA_GLOBALSINDEX</code> was removed.
-You must get the global environment from the registry
-(see <a href="#4.5">&sect;4.5</a>).
-</li>
-
-<li>
-Pseudoindex <code>LUA_ENVIRONINDEX</code>
-and functions <code>lua_getfenv</code>/<code>lua_setfenv</code>
-were removed,
-as C&nbsp;functions no longer have environments.
-</li>
-

-
-<H2><A NAME="about">About Lua</A></H2>
-
-<P>
-Lua is a powerful, fast, lightweight, embeddable scripting language
-developed by a
-<A HREF="http://www.lua.org/authors.html">team</A>
-at
-<A HREF="http://www.puc-rio.br/">PUC-Rio</A>,
-the Pontifical Catholic University of Rio de Janeiro in Brazil.
-Lua is
-<A HREF="#license">free software</A>
-used in many products and projects around the world.
-
-<P>
-Lua's
-<A HREF="http://www.lua.org/">official web site</A>
-provides complete information
-about Lua,
-including
-an
-<A HREF="http://www.lua.org/about.html">executive summary</A>
-and
-updated
-<A HREF="http://www.lua.org/docs.html">documentation</A>,
-especially the
-<A HREF="http://www.lua.org/manual/5.2/">reference manual</A>,
-which may differ slightly from the
-<A HREF="contents.html">local copy</A>
-distributed in this package.
-
-<H2><A NAME="install">Installing Lua</A></H2>
-
-<P>
-Lua is distributed in
-<A HREF="http://www.lua.org/ftp/">source</A>
-form.
-You need to build it before using it.
-Building Lua should be straightforward
-because
-Lua is implemented in pure ANSI C and compiles unmodified in all known
-platforms that have an ANSI C compiler.
-Lua also compiles unmodified as C++.
-The instructions given below for building Lua are for Unix-like platforms.
-See also
-<A HREF="#other">instructions for other systems</A>
-and
-<A HREF="#customization">customization options</A>.
-
-<P>
-If you don't have the time or the inclination to compile Lua yourself,
-get a binary from
-<A HREF="http://lua-users.org/wiki/LuaBinaries">LuaBinaries</A>.
-Try also
-<A HREF="http://luadist.org/">LuaDist</A>,
-a multi-platform distribution of Lua that includes batteries.
-
-<H3>Building Lua</H3>
-
-<P>
-In most Unix-like platforms, simply do "<KBD>make</KBD>" with a suitable target.
-Here are the details.
-
-<OL>
-<LI>
-Open a terminal window and move to
-the top-level directory, which is named <TT>lua-5.2.x</TT>.
-The <TT>Makefile</TT> there controls both the build process and the installation process.
-<P>
-<LI>
-  Do "<KBD>make</KBD>" and see if your platform is listed.
-  The platforms currently supported are:
-<P>
-<P CLASS="display">
-   aix ansi bsd freebsd generic linux macosx mingw posix solaris
-</P>
-<P>
-  If your platform is listed, just do "<KBD>make xxx</KBD>", where xxx
-  is your platform name.
-<P>
-  If your platform is not listed, try the closest one or posix, generic,
-  ansi, in this order.
-<P>
-<LI>
-The compilation takes only a few moments
-and produces three files in the <TT>src</TT> directory:
-lua (the interpreter),
-luac (the compiler),
-and liblua.a (the library).
-<P>
-<LI>
-  To check that Lua has been built correctly, do "<KBD>make test</KBD>"
-  after building Lua. This will run the interpreter and print its version.
-</OL>
-<P>
-If you're running Linux and get compilation errors,
-make sure you have installed the <TT>readline</TT> development package
-(which is probably named <TT>libreadline-dev</TT> or <TT>readline-devel</TT>).
-If you get link errors after that,
-then try "<KBD>make linux MYLIBS=-ltermcap</KBD>".
-
-<H3>Installing Lua</H3>
-<P>
-  Once you have built Lua, you may want to install it in an official
-  place in your system. In this case, do "<KBD>make install</KBD>". The official
-  place and the way to install files are defined in the <TT>Makefile</TT>. You'll
-  probably need the right permissions to install files.
-
-<P>
-  To build and install Lua in one step, do "<KBD>make xxx install</KBD>",
-  where xxx is your platform name.
-
-<P>
-  To install Lua locally, do "<KBD>make local</KBD>".
-  This will create a directory <TT>install</TT> with subdirectories
-  <TT>bin</TT>, <TT>include</TT>, <TT>lib</TT>, <TT>man</TT>, <TT>share</TT>,
-  and install Lua as listed below.
-
-  To install Lua locally, but in some other directory, do
-  "<KBD>make install INSTALL_TOP=xxx</KBD>", where xxx is your chosen directory.
-  The installation starts in the <TT>src</TT> and <TT>doc</TT> directories,
-  so take care if <TT>INSTALL_TOP</TT> is not an absolute path.
-
-<DL CLASS="display">
-<DT>
-    bin:
-<DD>
-    lua luac
-<DT>
-    include:
-<DD>
-    lua.h luaconf.h lualib.h lauxlib.h lua.hpp
-<DT>
-    lib:
-<DD>
-    liblua.a
-<DT>
-    man/man1:
-<DD>
-    lua.1 luac.1
-</DL>
-
-<P>
-  These are the only directories you need for development.
-  If you only want to run Lua programs,
-  you only need the files in <TT>bin</TT> and <TT>man</TT>.
-  The files in <TT>include</TT> and <TT>lib</TT> are needed for
-  embedding Lua in C or C++ programs.
-
-<H3><A NAME="customization">Customization</A></H3>
-<P>
-  Three kinds of things can be customized by editing a file:
-<UL>
-    <LI> Where and how to install Lua &mdash; edit <TT>Makefile</TT>.
-    <LI> How to build Lua &mdash; edit <TT>src/Makefile</TT>.
-    <LI> Lua features &mdash; edit <TT>src/luaconf.h</TT>.
-</UL>
-
-<P>
-  You don't actually need to edit the Makefiles because you may set the
-  relevant variables in the command line when invoking make.
-  Nevertheless, it's probably best to edit and save the Makefiles to
-  record the changes you've made.
-
-<P>
-  On the other hand, if you need to customize some Lua features, you'll need
-  to edit <TT>src/luaconf.h</TT> before building and installing Lua.
-  The edited file will be the one installed, and
-  it will be used by any Lua clients that you build, to ensure consistency.
-  Further customization is available to experts by editing the Lua sources.
-
-<P>
-  We strongly recommend that you enable dynamic loading in <TT>src/luaconf.h</TT>.
-  This is done automatically for all platforms listed above that have
-  this feature and also for Windows.
-
-<H3><A NAME="other">Building Lua on other systems</A></H3>
-
-<P>
-  If you're not using the usual Unix tools, then the instructions for
-  building Lua depend on the compiler you use. You'll need to create
-  projects (or whatever your compiler uses) for building the library,
-  the interpreter, and the compiler, as follows:
-
-<DL CLASS="display">
-<DT>
-library:
-<DD>
-lapi.c lcode.c lctype.c ldebug.c ldo.c ldump.c lfunc.c lgc.c llex.c
-lmem.c lobject.c lopcodes.c lparser.c lstate.c lstring.c ltable.c
-ltm.c lundump.c lvm.c lzio.c
-lauxlib.c lbaselib.c lbitlib.c lcorolib.c ldblib.c liolib.c
-lmathlib.c loslib.c lstrlib.c ltablib.c loadlib.c linit.c
-<DT>
-interpreter:
-<DD>
-  library, lua.c
-<DT>
-compiler:
-<DD>
-  library, luac.c
-</DL>
-
-<P>
-  To use Lua as a library in your own programs you'll need to know how to
-  create and use libraries with your compiler. Moreover, to dynamically load
-  C libraries for Lua you'll need to know how to create dynamic libraries
-  and you'll need to make sure that the Lua API functions are accessible to
-  those dynamic libraries &mdash; but <EM>don't</EM> link the Lua library
-  into each dynamic library. For Unix, we recommend that the Lua library
-  be linked statically into the host program and its symbols exported for
-  dynamic linking; <TT>src/Makefile</TT> does this for the Lua interpreter.
-  For Windows, we recommend that the Lua library be a DLL.
-  In all cases, the compiler luac should be linked statically.
-
-<P>
-  As mentioned above, you may edit <TT>src/luaconf.h</TT> to customize
-  some features before building Lua.
-

-** Some notes about garbage-collected objects:  All objects in Lua must
-** be kept somehow accessible until being freed.
-**
-** Lua keeps most objects linked in list g->allgc. The link uses field
-** 'next' of the CommonHeader.
-**
-** Strings are kept in several lists headed by the array g->strt.hash.
-**
-** Open upvalues are not subject to independent garbage collection. They
-** are collected together with their respective threads. Lua keeps a
-** double-linked list with all open upvalues (g->uvhead) so that it can
-** mark objects referred by them. (They are always gray, so they must
-** be remarked in the atomic step. Usually their contents would be marked
-** when traversing the respective threads, but the thread may already be
-** dead, while the upvalue is still accessible through closures.)
-**
-** Objects with finalizers are kept in the list g->finobj.
-**
-** The list g->tobefnz links all objects being finalized.
