+=head1 SYNOPSIS

+
+=head1 DESCRIPTION
+
+C<TAP::Parser::Grammar> tokenizes lines from a L<TAP::Parser::Iterator> and
+constructs L<TAP::Parser::Result> subclasses to represent the tokens.
+
+Do not attempt to use this class directly.  It won't make sense.  It's mainly
+here to ensure that we will be able to have pluggable grammars when TAP is
+expanded at some future date (plus, this stuff was really cluttering the
+parser).

+  my $grammar = TAP::Parser::Grammar->new({
+      iterator => $iterator,
+      parser   => $parser,
+      version  => $version,
+  });
+
+Returns L<TAP::Parser> grammar object that will parse the TAP stream from the
+specified iterator.  Both C<iterator> and C<parser> are required arguments.
+If C<version> is not set it defaults to C<12> (see L</set_version> for more
+details).

+=head1 TAP GRAMMAR
+
+B<NOTE:>  This grammar is slightly out of date.  There's still some discussion
+about it and a new one will be provided when we have things better defined.
+
+The L<TAP::Parser> does not use a formal grammar because TAP is essentially a
+stream-based protocol.  In fact, it's quite legal to have an infinite stream.
+For the same reason that we don't apply regexes to streams, we're not using a
+formal grammar here.  Instead, we parse the TAP in lines.
+
+For purposes for forward compatibility, any result which does not match the
+following grammar is currently referred to as
+L<TAP::Parser::Result::Unknown>.  It is I<not> a parse error.
+
+A formal grammar would look similar to the following:
+
+ (*
+     For the time being, I'm cheating on the EBNF by allowing
+     certain terms to be defined by POSIX character classes by
+     using the following syntax:
+
+       digit ::= [:digit:]
+
+     As far as I am aware, that's not valid EBNF.  Sue me.  I
+     didn't know how to write "char" otherwise (Unicode issues).
+     Suggestions welcome.
+ *)
+
+ tap            ::= version? { comment | unknown } leading_plan lines
+                    |
+                    lines trailing_plan {comment}
+
+ version        ::= 'TAP version ' positiveInteger {positiveInteger} "\n"
+
+ leading_plan   ::= plan skip_directive? "\n"
+
+ trailing_plan  ::= plan "\n"
+
+ plan           ::= '1..' nonNegativeInteger
+
+ lines          ::= line {line}
+
+ line           ::= (comment | test | unknown | bailout ) "\n"
+
+ test           ::= status positiveInteger? description? directive?
+
+ status         ::= 'not '? 'ok '
+
+ description    ::= (character - (digit | '#')) {character - '#'}
+
+ directive      ::= todo_directive | skip_directive
+
+ todo_directive ::= hash_mark 'TODO' ' ' {character}
+
+ skip_directive ::= hash_mark 'SKIP' ' ' {character}
+
+ comment        ::= hash_mark {character}
+
+ hash_mark      ::= '#' {' '}
+
+ bailout        ::= 'Bail out!' {character}
+
+ unknown        ::= { (character - "\n") }
+
+ (* POSIX character classes and other terminals *)
+
+ digit              ::= [:digit:]
+ character          ::= ([:print:] - "\n")
+ positiveInteger    ::= ( digit - '0' ) {digit}
+ nonNegativeInteger ::= digit {digit}

+=head3 C<get_select_handles>
+
+Return a list of filehandles that may be used upstream in a select()
+call to signal that this Iterator is ready. Iterators that are not
+handle-based should return an empty list.
+
+The default implementation does nothing.

+=head1 SUBCLASSING
+
+Please see L<TAP::Parser/SUBCLASSING> for a subclassing overview.
+
+=head2 Example
+
+If we've done things right, you'll probably want to write a new source,
+rather than sub-classing this (see L<TAP::Parser::SourceHandler> for that).
+
+But in case you find the need to...
+
+  package MyIteratorFactory;
+
+  use strict;
+
+  use base 'TAP::Parser::IteratorFactory';
+
+  # override source detection algorithm
+  sub detect_source {
+    my ($self, $raw_source_ref, $meta) = @_;
+    # do detective work, using $meta and whatever else...
+  }

+=head1 DESCRIPTION
+
+C<TAP::Parser::Multiplexer> gathers input from multiple TAP::Parsers.
+Internally it calls select on the input file handles for those parsers
+to wait for one or more of them to have input available.
+
+See L<TAP::Harness> for an example of its use.

+=head2 DESCRIPTION
+
+This is a simple base class used by L<TAP::Parser> to store objects that

+=head1 SUBCLASSING
+
+Please see L<TAP::Parser/SUBCLASSING> for a subclassing overview.
+
+Remember: if you want your subclass to be automatically used by the parser,
+you'll have to register it with L<TAP::Parser::ResultFactory/register_type>.
+
+If you're creating a completely new result I<type>, you'll probably need to
+subclass L<TAP::Parser::Grammar> too, or else it'll never get used.

+
+This is a simple factory class which returns a L<TAP::Parser::Result> subclass
+representing the current bit of test data from TAP (usually a single line).
+It is used primarily by L<TAP::Parser::Grammar>.  Unless you're subclassing,
+you probably won't need to use this module directly.

+
+=head2 Class Methods
+
+=head3 C<new>

+Creates a new factory class.
+I<Note:> You currently don't need to instantiate a factory in order to use it.
+

+
+=head3 C<class_for>
+
+Takes one argument: C<$type>.  Returns the class for this $type, or C<croak>s
+with an error.
+
+=head3 C<register_type>
+
+Takes two arguments: C<$type>, C<$class>
+
+This lets you override an existing type with your own custom type, or register
+a completely new type, eg:
+
+  # create a custom result type:
+  package MyResult;
+  use strict;
+  use base 'TAP::Parser::Result';
+
+  # register with the factory:
+  TAP::Parser::ResultFactory->register_type( 'my_type' => __PACKAGE__ );
+
+  # use it:
+  my $r = TAP::Parser::ResultFactory->( { type => 'my_type' } );
+
+Your custom type should then be picked up automatically by the L<TAP::Parser>.

+=head1 SUBCLASSING
+
+Please see L<TAP::Parser/SUBCLASSING> for a subclassing overview.
+
+There are a few things to bear in mind when creating your own
+C<ResultFactory>:
+
+=over 4
+
+=item 1
+
+The factory itself is never instantiated (this I<may> change in the future).
+This means that C<_initialize> is never called.
+
+=item 2
+
+C<TAP::Parser::Result-E<gt>new> is never called, $tokens are reblessed.
+This I<will> change in a future version!
+
+=item 3
+
+L<TAP::Parser::Result> subclasses will register themselves with
+L<TAP::Parser::ResultFactory> directly:
+
+  package MyFooResult;
+  TAP::Parser::ResultFactory->register_type( foo => __PACKAGE__ );
+
+Of course, it's up to you to decide whether or not to ignore them.

+TAP::Parser::Scheduler - Schedule tests during parallel testing
+
+=head1 VERSION
+
+Version 3.48
+
+=cut
+
+our $VERSION = '3.48';
+
+=head1 SYNOPSIS
+
+    use TAP::Parser::Scheduler;
+
+=head1 DESCRIPTION
+
+=head1 METHODS
+
+=head2 Class Methods
+
+=head3 C<new>
+
+    my $sched = TAP::Parser::Scheduler->new(tests => \@tests);
+    my $sched = TAP::Parser::Scheduler->new(
+        tests => [ ['t/test_name.t','Test Description'], ... ],
+        rules => \%rules,
+    );
+
+Given 'tests' and optional 'rules' as input, returns a new
+C<TAP::Parser::Scheduler> object.  Each member of C<@tests> should be either a
+a test file name, or a two element arrayref, where the first element is a test
+file name, and the second element is a test description. By default, we'll use
+the test name as the description.
+
+The optional C<rules> attribute provides direction on which tests should be run
+in parallel and which should be run sequentially. If no rule data structure is
+provided, a default data structure is used which makes every test eligible to
+be run in parallel:
+
+    { par => '**' },
+
+The rules data structure is documented more in the next section.
+
+=head2 Rules data structure
+
+The "C<rules>" data structure is the the heart of the scheduler. It allows you
+to express simple rules like "run all tests in sequence" or "run all tests in
+parallel except these five tests.". However, the rules structure also supports
+glob-style pattern matching and recursive definitions, so you can also express
+arbitarily complicated patterns.
+
+The rule must only have one top level key: either 'par' for "parallel" or 'seq'
+for "sequence".
+
+Values must be either strings with possible glob-style matching, or arrayrefs
+of strings or hashrefs which follow this pattern recursively.
+
+Every element in an arrayref directly below a 'par' key is eligible to be run
+in parallel, while vavalues directly below a 'seq' key must be run in sequence.
+
+=head3 Rules examples
+
+Here are some examples:
+
+    # All tests be run in parallel (the default rule)
+    { par => '**' },
+
+    # Run all tests in sequence, except those starting with "p"
+    { par => 't/p*.t' },
+
+    # Run all tests in parallel, except those starting with "p"
+    {
+        seq => [
+                  { seq => 't/p*.t' },
+                  { par => '**'     },
+               ],
+    }
+
+    # Run some  startup tests in sequence, then some parallel tests then some
+    # teardown tests in sequence.
+    {
+        seq => [
+            { seq => 't/startup/*.t' },
+            { par => ['t/a/*.t','t/b/*.t','t/c/*.t'], }
+            { seq => 't/shutdown/*.t' },
+        ],
+    },
+
+
+=head3 Rules resolution
+
+=over 4
+
+=item * By default, all tests are eligible to be run in parallel. Specifying any of your own rules removes this one.
+
+=item * "First match wins". The first rule that matches a test will be the one that applies.
+
+=item * Any test which does not match a rule will be run in sequence at the end of the run.
+
+=item * The existence of a rule does not imply selecting a test. You must still specify the tests to run.
+
+=item * Specifying a rule to allow tests to run in parallel does not make the run in parallel. You still need specify the number of parallel C<jobs> in your Harness object.
+
+=back
+
+=head3 Glob-style pattern matching for rules
+
+We implement our own glob-style pattern matching. Here are the patterns it supports:
+
+    ** is any number of characters, including /, within a pathname
+    * is zero or more characters within a filename/directory name
+    ? is exactly one character within a filename/directory name
+    {foo,bar,baz} is any of foo, bar or baz.
+    \ is an escape character

+=head1 DESCRIPTION
+
+A TAP I<source> is something that produces a stream of TAP for the parser to
+consume, such as an executable file, a text file, an archive, an IO handle, a
+database, etc.  C<TAP::Parser::Source>s encapsulate these I<raw> sources, and
+provide some useful meta data about them.  They are used by
+L<TAP::Parser::SourceHandler>s, which do whatever is required to produce &
+capture a stream of TAP from the I<raw> source, and package it up in a
+L<TAP::Parser::Iterator> for the parser to consume.
+
+Unless you're writing a new L<TAP::Parser::SourceHandler>, a plugin or
+subclassing L<TAP::Parser>, you probably won't need to use this module directly.

+=head1 NAME
+
+TAP::Parser::SourceHandler - Base class for different TAP source handlers
+
+=head1 VERSION
+
+Version 3.48
+
+=cut
+
+our $VERSION = '3.48';
+
+=head1 SYNOPSIS
+
+  # abstract class - don't use directly!
+  # see TAP::Parser::IteratorFactory for general usage
+
+  # must be sub-classed for use
+  package MySourceHandler;
+  use base 'TAP::Parser::SourceHandler';

+
+  # see example below for more details
+
+=head1 DESCRIPTION
+
+This is an abstract base class for L<TAP::Parser::Source> handlers / handlers.
+
+A C<TAP::Parser::SourceHandler> does whatever is necessary to produce & capture
+a stream of TAP from the I<raw> source, and package it up in a
+L<TAP::Parser::Iterator> for the parser to consume.
+
+C<SourceHandlers> must implement the I<source detection & handling> interface
+used by L<TAP::Parser::IteratorFactory>.  At 2 methods, the interface is pretty
+simple: L</can_handle> and L</make_source>.
+
+Unless you're writing a new L<TAP::Parser::SourceHandler>, a plugin, or
+subclassing L<TAP::Parser>, you probably won't need to use this module directly.
+
+=head1 METHODS
+
+=head2 Class Methods
+
+=head3 C<can_handle>
+
+I<Abstract method>.
+
+  my $vote = $class->can_handle( $source );
+
+C<$source> is a L<TAP::Parser::Source>.
+
+Returns a number between C<0> & C<1> reflecting how confidently the raw source
+can be handled.  For example, C<0> means the source cannot handle it, C<0.5>
+means it may be able to, and C<1> means it definitely can.  See
+L<TAP::Parser::IteratorFactory/detect_source> for details on how this is used.

+}
+
+=head3 C<make_iterator>
+
+I<Abstract method>.
+
+  my $iterator = $class->make_iterator( $source );
+
+C<$source> is a L<TAP::Parser::Source>.
+
+Returns a new L<TAP::Parser::Iterator> object for use by the L<TAP::Parser>.

+=head1 SUBCLASSING
+
+Please see L<TAP::Parser/SUBCLASSING> for a subclassing overview, and any
+of the subclasses that ship with this module as an example.  What follows is
+a quick overview.
+
+Start by familiarizing yourself with L<TAP::Parser::Source> and
+L<TAP::Parser::IteratorFactory>.  L<TAP::Parser::SourceHandler::RawTAP> is
+the easiest sub-class to use as an example.
+
+It's important to point out that if you want your subclass to be automatically
+used by L<TAP::Parser> you'll have to and make sure it gets loaded somehow.
+If you're using L<prove> you can write an L<App::Prove> plugin.  If you're
+using L<TAP::Parser> or L<TAP::Harness> directly (e.g. through a custom script,
+L<ExtUtils::MakeMaker>, or L<Module::Build>) you can use the C<config> option
+which will cause L<TAP::Parser::IteratorFactory/load_sources> to load your
+subclass).
+
+Don't forget to register your class with
+L<TAP::Parser::IteratorFactory/register_handler>.

+
+The command to run is built as follows:
+
+  $perl @switches $perl_script @test_args
+
+The perl command to use is determined by L</get_perl>.  The command generated
+is guaranteed to preserve:
+
+  PERL5LIB
+  PERL5OPT
+  Taint Mode, if set in the script's shebang
+
+I<Note:> the command generated will I<not> respect any shebang line defined in
+your Perl script.  This is only a problem if you have compiled a custom version
+of Perl or if you want to use a specific version of Perl for one test and a
+different version for another, for example:
+
+  #!/path/to/a/custom_perl --some --args
+  #!/usr/local/perl-5.6/bin/perl -w
+
+Currently you need to write a plugin to get around this.
