+=======================================

+
+================================== intro_tag
+=== Introduction =================
+==================================
+
+Interpreter preprocesses input files before their contents is fed to TeX. It
+is meant to write document with whatever markup one wishes to define while
+using normal TeX macros in the background. As a simple example, suppose you
+have a macro "\bold" to put text in boldface; then Interpreter lets you map
+"*text*", or "<strong>text</strong>", or simply "!text", or anything else, to
+"\bold{text}". Interpreter doesn't perform any trickery with active
+characters; instead, it manipulates the strings representing the lines of
+a file and search for patterns.
+
+There are two main advantages: first, TeX documents can be typeset with
+a completely non-TeX syntax; second, if one uses some lightweight markup
+language, the source file is much easier to read and might even be more useful
+than the typeset PDF file, e.g. for some technical documentation you want to
+read directly in your text editor while writing code (powerful editors
+generally have their own documentation in such a format, for a good reason).
+A third advantage, not explored in this documentation, is that while feeding
+modified lines to TeX you can also translate the original lines into, say,
+HTML, and write them to an external file, thus creating both PDF and HTML
+output at once.
+
+
+
+================================== input_tag
+=== Input files ==================
+==================================
+
+Once Interpreter is loaded with
+
+ \input interpreter
+
+in plain TeX or
+
+ \usepackage{interpreter}
+
+in LaTeX, files to be processed are input as follows:
+
+ \interpretfile{<language>}{<file>}
+
+There should exist a file "i-<language>.lua" containing the language used in
+<file>. For instance, the source of this documentation is
+"interpreter-doc.txt", input in the master file "interpreter-doc.tex" with
+
+ \interpretfile{doc}{interpreter-doc.txt}
+
+and the interpretation to be used is defined in "i-doc.lua". The contents of
+such an interpretation file is the object of the rest of this documentation.
+
+
+
+================================== paragraphs_tag
+=== Paragraphs ===================
+==================================
+
+Interpreter doesn't process lines one by one. Instead, it gathers an entire
+paragraph and then processes the lines. It is important because you can
+manipulate an entire paragraph when a given pattern is detected, and modify
+several lines according to what happens in only one. A paragraph in
+Interpreter has nothing to do with what TeX considers a paragraph; instead, it
+is defined by the following string.
+
+> interpreter.paragraph [Default: blank line with spaces ignored]
+ A string to be interpreted as a paragraph boundary when Interpreter collects
+ lines before processing them. The string actually represents a pattern, so
+ magic characters are obeyed. The default is "%s*", i.e. a blank line is
+ considered a paragraph boundary, spaces notwithstanding. Of course, the end
+ of the file itself is a paragraph boundary.
+
+
+
+================================== patterns_tag
+=== Declaring patterns ===========
+==================================
+
+Once the lines of a paragraph have been collected, Interpreter searches them
+trying to match declared patterns, but it doesn't do so indiscriminately:
+patterns are searched in a given order, as explained below.
+
+Patterns are searched for in each line only, i.e. no match can occur across
+lines. However, since you can manipulate entire paragraphs based on a match in
+one line, the limitation easily vanishes.
+
+> interpreter.add_pattern(<table>)
+ This is the basic function used to defined patterns. The <table> may
+ contain the following entries, along other entries Interpreter won't use
+ but which can be useful to you, especially with "call" below. The function
+ returns a table.
+
+>> class [Default: "intepreter.default_class"]
+ The class of the pattern. See the section on classes.
+
+>> pattern
+ The pattern to match. Lua's magic characters are in force and should be
+ escaped with "%" if necessary, unless "nomagic" is "true" (or the pattern
+ itself is the result of "interpreter.nomagic").
+
+>> nomagic [Default: "false"]
+ A boolean deciding whether the pattern should be transformed with
+ "interpreter.nomagic".
+
+>> replace
+ The replacement for the pattern, applied only if there is no "call" entry.
+ This may be a string, a table or a function. Interpreter simply executes
+ something similar to "string.gsub()", hence the replacement follows this
+ function's ordinary syntax. More precisely, if "replace" is a string, the
+ pattern is replaced with it; in this string, "%n" may be used to denote the
+ _n_th capture in the pattern. If "replace" is a table, the first capture or
+ the entire match (if there is no capture) is used as the key, and the
+ associated value is used as the replacement. If "replace" is a function, it
+ is called with the captures passed as arguments, or the entire match if
+ there is no capture. For instance, the following pattern will replace all
+ "*text*" with "\bold{text}":
+
+ interpreter.add_pattern{
+ pattern = "%*(.-)%*",
+ replace = [[\bold{%1}]]
+ }
+
+>> offset [Default: 0]
+ The number of positions Interpreter should shift to the right after a match
+ has occurred. Normally, Interpreter starts searching for another occurrence
+ of the current pattern at the same position where it found the last one.
+ However, loops might easily occur: the replacement for a pattern may very
+ well contain another match for the same pattern, so Interpreter will get
+ stuck. Suppose for instance you want to replace "TeX" with "\TeX". The
+ first match will do that, but then Interpreter will start searching again
+ at the backslash, producing "\\TeX", then "\\\TeX", etc. In this case, if
+ you set "offset" to 2 in the pattern, then search will start again at the
+ "e" and no new match will occur.
+
+>> call
+ This entry shall contain a function to be called if there is a match (if
+ this entry exists, "replace" isn't applied). It is meant to perform complex
+ tasks that aren't amenable to simple string replacement. The function will
+ be executed as follows:
+
+ function (paragraph, line, index, pattern)
+
+ "paragraph" is a table representing the current paragraph; lines are stored
+ at successive indices. The last line of this paragraph is always the
+ paragraph boundary (see "interpreter.paragraph"), unless the paragraph
+ stopped at the end of the file. The second argument, "line", is a number
+ representing the index in "paragraph" containing the line where the pattern
+ was found; "index" is the position in this line where the match occurred.
+ Finally, "pattern" is the entire table declared with
+ "interpreter.add_pattern" and containing all the entries discussed here.
+
+ The function may return zero, one, or two numbers. If it returns none, the
+ search for the next occurrence of the pattern will start again on the same
+ line (rather, on the line with the same position in the paragraph), at
+ "index". If it returns one number, the search will resume at the same line
+ but at position _n_, with _n_ the returned number. Finally, if two numbers
+ are returned, the search will resume at line _m_ at position _n_, _m_ and
+ _n_ being the returned values. Specifying which line should be examined
+ when the search resumes might be necessary if the function adds new lines
+ in the paragraph _before_ the current line, since Interpreter only keeps
+ count of line numbers.
+
+ The entire paragraph can thus be modified if necessary. For instance,
+ suppose you want to declare comments in your source file with only
+ "!Comment" in the first line, i.e. TeX should ignore a paragraph such as:
+
+ !Comment
+ This should be ignored
+ by TeX
+
+ Then the following pattern will do (where the function requires only the
+ first argument):
+
+ local function comment (paragraph)
+ for n, l in ipairs(paragraph) do
+ paragraph[n] = "%" .. l
+ end
+ end
+ interpreter.add_pattern{
+ pattern = "^!Comment",
+ call = comment
+ }
+
+> interpreter.nomagic (string)
+ A function which reverses the usual Lua magic for patterns: ordinary magic
+ characters are normal characters here, unless they are prefixed with "%", in
+ which case they are magic again. For instance, a pattern like ".+" is
+ normally interpreted as ``one or more characters''. If passed to this
+ function, a pattern is returned meaning ``a dot followed by a plus sign''.
+ On the contrary, "%.%+" normally has the second interpretation, while with
+ "interpreter.nomagic" it has the first one. The function makes another
+ transformation: "..." is used to denote a capture "(.-)". Thus
+ "interpreter.nomagic('*...*')" returns a pattern matching any number of
+ characters surrounded by stars and capturing those characters; this would be
+ expressed in ordinary Lua magic as "%*(.-)%*".
+
+
+
+================================== classes_tag
+=== Classes ======================
+==================================
+
+As already alluded to, the search for patterns isn't done at random. Instead,
+patterns are organized in classes, which are applied one after the other. More
+precisely, the process is as follows: Interpreter searches the entire
+paragraph for the first pattern in class~1, then for the second pattern in the
+same class, then for the third, etc., then when there is no pattern left in
+class~1 it does the same with class~2, up to class~_n_, where _n_ is the
+hightest class number such that there exists a class _n - 1_ (in other words,
+classes should be numbered consecutively). Finally, the same goes for the
+patterns in class~0 (which always exists, even if it contains no pattern).
+
+Inside a class, patterns are ordered by length from long to short, or
+alphabetically if two patterns have the same length. This means that if you
+use e.g. "/text/" for italics and "//text//" for bold, you don't need to put
+the second pattern in a class before the first to avoid "//text//" being
+interpreted as two empty arguments in italics surrounding a text in roman.
+Since the way the bold-pattern will be declared, e.g. "//(.-)//", is probably
+longer than for the italic-pattern, e.g. "/(.-)/", it will always match first.
+
+That said, the sorting isn't very clever and simply relies on the number of
+symbols, no matter what they mean; in the patterns above, the parentheses
+denote a capture but they still count in the pattern's length as understood by
+Interpreter. Alternatively, while ".*" denotes ``zero or more character'' and
+"%+" means ``a plus sign'' ("+" being magic, you have to escape it to refer to
+it), in Interpreter's eye the two patterns have the same length: two. Finally,
+one should be aware that patterns declared with a "nomagic" entry set to
+"true" are sorted after they've been transformed (so that their real length
+might not be obvious). So classes are needed when patterns need a proper
+ordering no matter their lengths. For instance, some patterns should always be
+declared first, as they protect input from Interpreter (see next section),
+while others might need to be declared last, as they rely on what previous
+patterns might have done. Besides, classes are metatables for the patterns
+they contain.
+
+> interpreter.default_class [Default: 1]
+ All patterns belong to a class, even though you may omit the "class" entry
+ when declaring one. In this case, the pattern is assigned to the class
+ denoted by this number.
+
+> interpreter.set_class(number, table)
+ Defines class "number" as "table". Classes don't need to be defined
+ beforehand for patterns to be added to them (rather, Interpreter defines
+ them implicitly when needed). However, classes are also metatables for the
+ patterns, so that if there lacks an entry in a pattern's table, the class's
+ entry is used if it exists. The function returns a table.
+
+
+
+================================== protect_tag
+=== Protecting input =============
+==================================
+
+Sometimes you want Interpreter to refrain from interpreting; that is most
+useful for verbatim code, for instance. There are various ways to do that.
+
+> interpreter.active [Default: true]
+ A boolean switching Interpreter on and off. Beware, the switching applies
+ only starting at the next paragraph.
+
+> interpreter.protect([line])
+ A function protecting all or part of the current paragraph. If "line" is
+ given, it should be a number _n_, and line _n_ in the current paragraph will
+ be protected; without "line", the entire paragraph is protected. Protecting
+ means that the patterns not yet searched for will be ignored. For instance,
+ if you want material to be read verbatim when surrounded with "<code>" and
+ "</code>", you can declare a pattern as follows:
+
+ local function verbatim (buffer)
+ buffer[1] = "\\verbatim"
+ buffer[#buffer - 1] = "\\endverbatim"
+ intepreter.protect()
+ end
+ interpreter.add_pattern{
+ pattern = "^%s*<code>%*s$",
+ call = verbatim,
+ class = 1
+ }
+
+ This code is extremely simplified : it assumes that "<code>" and "</code>"
+ starts and ends the paragraph and that "</code>" isn't the last line of the
+ file (otherwise it'd also be the last line in the paragraph, whereas here
+ the last one is the paragraph boundary). An important point is that the
+ pattern belongs to the first class, so it is called before all other
+ patterns (provided there is no shorter pattern in class~1) and prevents them
+ from doing anything, since the entire paragraph is protected. (Typesetting
+ the material as verbatim material obviously depends on the "\verbatim"
+ macro, not on Interpreter.)
+
+> interpreter.escape
+ A character which prevents patterns from being replaced if immediately
+ preceded by it. As an example, if "interpreter.escape = '_'", and "*text*"
+ denotes italic, then "*text*" will produce _text_ while "_*text*" will
+ produce *text*. Once a paragraph has been processed, Interpreter removes all
+ escape characters. Only one character can be an escape character.
+
+> interpreter.protector(left[, right]) ["right" defaults to "left"]
+ Defines two characters to protect what they surround. In other words,
+ Interpreter replaces patterns only if the match isn't found between "left"
+ and "right". Unlike the escape character, you can define as many protectors
+ as you wish; and unlike the escape character again, Interpreter _doesn't_
+ remove them once the paragraph has been processed, so you must take care of
+ them. For instance:
+
+ intepreter.protector('"')
+ interpreter.add_pattern{
+ pattern = '"(.-)"',
+ replace = '\\verb`%1`',
+ class = 0
+ }
+
+ Anything between double quotes will be left untouched; then, when the
+ paragraph has been processed for all other classes, a pattern in class~0
+ calls the "\verb" command to take care of the argument. Note that the
+ protectors should enclose what they protect without coinciding with it; this
+ is not the case here, which is why the pattern is applied.
+
+> interpreter.direct [Default: two percent signs then "I" and at least one space]
+ A string, actually a pattern, signalling that the line which it begins
+ should be processed as Lua code. The default is "%%%%I%s+", i.e. "%%I"
+ followed by at least one space. The pattern shouldn't declare itself as
+ attached to the beginning of the line (as in "^%%%%I%s+") because they will
+ be matched at the beginning of the line only anyway. The line is processed
+ with the "loadstring" function, and then turned into an empty line. For
+ instance:
+
+ %%I interpreter.active = false
+ This won't be interpreted...
+ %%I interpreter.active = true
+
+ As this example shows, lines flagged with "interpreter.direct" don't obey
+ "interpreter.active" and are always processed as described above.
+
+
+
+================================== technical_tag
+=== Technical stuff ==============
+==================================
+
+You don't have to bother with this section if you don't mind how Interpreter
+does its job; actually you won't learn much anyway.
+
+> interpreter.reset()
+ A function which resets everything to default and deletes classes. It is used
+ when calling "\interpretefile" so that new interpretetions start from zero.
+
+> interpreter.register(function)
+ A function called to put Interpreter's main function into the
+ "post_linebreak_filter" callback; you can redefine it at will. If it is
+ undefined, "callback.register()" is used, unless "luatexbase.add_to_callback()"
+ is detected. (The detection takes place at the first call to
+ "\interpretfile", so there is no need to load Interpreter after
+ "luatexbase".)
+
+> interpreter.unregister(function)
+ A function called to remove Interpreter's main function from the
+ "post_linebreak_filter" callback. It works similarly to the previous one.

+Here's how multiline verbatim is handled; in the source it is simply marked by

+to mark it. To be properly processed by TeX, the code should be surrounded by
+"\verbatim" and "\verbatim/" (my way of signalling blocks). Those must be on
+their own lines, so we insert a line at the beginning and at the end of the
+paragraph: for the closing "\verbatim/", we can simply replace the last line
+of the paragraph, which is the boundary line, unless we're at the end of the
+file. But for the opening "\verbatim" a line must be added at the beginning of
+the paragraph; thus line numbers in the original source file and in its
+processed version don't match anymore, and this might be annoying when TeX
+reports erros. Besides, blank verbatim lines aren't handled correctly and
+create a new verbatim block instead. So this way of marking verbatim material
+is good for small documents, but explicit marking is cleaner and more
+powerful (albeit not so good-looking in the source file).

+protected, so Interpreter leaves it alone afterward (remember the default
+class is 3). Of course, the first ten space characters are removed.
