NAME
    TAP::Parser - Parse TAP output

VERSION
    Version 3.43

SYNOPSIS
        use TAP::Parser;

        my $parser = TAP::Parser->new( { source => $source } );

        while ( my $result = $parser->next ) {
            print $result->as_string;
        }

DESCRIPTION
    "TAP::Parser" is designed to produce a proper parse of TAP output. For an example of how to run
    tests through this module, see the simple harnesses "examples/".

    There's a wiki dedicated to the Test Anything Protocol:

    <http://testanything.org>

    It includes the TAP::Parser Cookbook:

    <http://testanything.org/testing-with-tap/perl/tap::parser-cookbook.html>

METHODS
  Class Methods
   "new"
     my $parser = TAP::Parser->new(\%args);

    Returns a new "TAP::Parser" object.

    The arguments should be a hashref with *one* of the following keys:

    *   "source"

        *CHANGED in 3.18*

        This is the preferred method of passing input to the constructor.

        The "source" is used to create a TAP::Parser::Source that is passed to the
        "iterator_factory_class" which in turn figures out how to handle the source and creates a
        <TAP::Parser::Iterator> for it. The iterator is used by the parser to read in the TAP
        stream.

        To configure the *IteratorFactory* use the "sources" parameter below.

        Note that "source", "tap" and "exec" are *mutually exclusive*.

    *   "tap"

        *CHANGED in 3.18*

        The value should be the complete TAP output.

        The *tap* is used to create a TAP::Parser::Source that is passed to the
        "iterator_factory_class" which in turn figures out how to handle the source and creates a
        <TAP::Parser::Iterator> for it. The iterator is used by the parser to read in the TAP
        stream.

        To configure the *IteratorFactory* use the "sources" parameter below.

        Note that "source", "tap" and "exec" are *mutually exclusive*.

    *   "exec"

        Must be passed an array reference.

        The *exec* array ref is used to create a TAP::Parser::Source that is passed to the
        "iterator_factory_class" which in turn figures out how to handle the source and creates a
        <TAP::Parser::Iterator> for it. The iterator is used by the parser to read in the TAP
        stream.

        By default the TAP::Parser::SourceHandler::Executable class will create a
        TAP::Parser::Iterator::Process object to handle the source. This passes the array reference
        strings as command arguments to IPC::Open3::open3:

         exec => [ '/usr/bin/ruby', 't/my_test.rb' ]

        If any "test_args" are given they will be appended to the end of the command argument list.

        To configure the *IteratorFactory* use the "sources" parameter below.

        Note that "source", "tap" and "exec" are *mutually exclusive*.

    The following keys are optional.

    *   "sources"

        *NEW to 3.18*.

        If set, "sources" must be a hashref containing the names of the TAP::Parser::SourceHandlers
        to load and/or configure. The values are a hash of configuration that will be accessible to
        the source handlers via "config_for" in TAP::Parser::Source.

        For example:

          sources => {
            Perl => { exec => '/path/to/custom/perl' },
            File => { extensions => [ '.tap', '.txt' ] },
            MyCustom => { some => 'config' },
          }

        This will cause "TAP::Parser" to pass custom configuration to two of the built- in source
        handlers - TAP::Parser::SourceHandler::Perl, TAP::Parser::SourceHandler::File - and attempt
        to load the "MyCustom" class. See "load_handlers" in TAP::Parser::IteratorFactory for more
        detail.

        The "sources" parameter affects how "source", "tap" and "exec" parameters are handled.

        See TAP::Parser::IteratorFactory, TAP::Parser::SourceHandler and subclasses for more
        details.

    *   "callback"

        If present, each callback corresponding to a given result type will be called with the
        result as the argument if the "run" method is used:

         my %callbacks = (
             test    => \&test_callback,
             plan    => \&plan_callback,
             comment => \&comment_callback,
             bailout => \&bailout_callback,
             unknown => \&unknown_callback,
         );

         my $aggregator = TAP::Parser::Aggregator->new;
         for my $file ( @test_files ) {
             my $parser = TAP::Parser->new(
                 {
                     source    => $file,
                     callbacks => \%callbacks,
                 }
             );
             $parser->run;
             $aggregator->add( $file, $parser );
         }

    *   "switches"

        If using a Perl file as a source, optional switches may be passed which will be used when
        invoking the perl executable.

         my $parser = TAP::Parser->new( {
             source   => $test_file,
             switches => [ '-Ilib' ],
         } );

    *   "test_args"

        Used in conjunction with the "source" and "exec" option to supply a reference to an @ARGV
        style array of arguments to pass to the test program.

    *   "spool"

        If passed a filehandle will write a copy of all parsed TAP to that handle.

    *   "merge"

        If false, STDERR is not captured (though it is 'relayed' to keep it somewhat synchronized
        with STDOUT.)

        If true, STDERR and STDOUT are the same filehandle. This may cause breakage if STDERR
        contains anything resembling TAP format, but does allow exact synchronization.

        Subtleties of this behavior may be platform-dependent and may change in the future.

    *   "grammar_class"

        This option was introduced to let you easily customize which *grammar* class the parser
        should use. It defaults to TAP::Parser::Grammar.

        See also "make_grammar".

    *   "result_factory_class"

        This option was introduced to let you easily customize which *result* factory class the
        parser should use. It defaults to TAP::Parser::ResultFactory.

        See also "make_result".

    *   "iterator_factory_class"

        *CHANGED in 3.18*

        This option was introduced to let you easily customize which *iterator* factory class the
        parser should use. It defaults to TAP::Parser::IteratorFactory.

  Instance Methods
   "next"
      my $parser = TAP::Parser->new( { source => $file } );
      while ( my $result = $parser->next ) {
          print $result->as_string, "\n";
      }

    This method returns the results of the parsing, one result at a time. Note that it is
    destructive. You can't rewind and examine previous results.

    If callbacks are used, they will be issued before this call returns.

    Each result returned is a subclass of TAP::Parser::Result. See that module and related classes
    for more information on how to use them.

   "run"
      $parser->run;

    This method merely runs the parser and parses all of the TAP.

   "make_grammar"
    Make a new TAP::Parser::Grammar object and return it. Passes through any arguments given.

    The "grammar_class" can be customized, as described in "new".

   "make_result"
    Make a new TAP::Parser::Result object using the parser's TAP::Parser::ResultFactory, and return
    it. Passes through any arguments given.

    The "result_factory_class" can be customized, as described in "new".

   "make_iterator_factory"
    *NEW to 3.18*.

    Make a new TAP::Parser::IteratorFactory object and return it. Passes through any arguments
    given.

    "iterator_factory_class" can be customized, as described in "new".

INDIVIDUAL RESULTS
    If you've read this far in the docs, you've seen this:

        while ( my $result = $parser->next ) {
            print $result->as_string;
        }

    Each result returned is a TAP::Parser::Result subclass, referred to as *result types*.

  Result types
    Basically, you fetch individual results from the TAP. The six types, with examples of each, are
    as follows:

    *   Version

         TAP version 12

    *   Plan

         1..42

    *   Pragma

         pragma +strict

    *   Test

         ok 3 - We should start with some foobar!

    *   Comment

         # Hope we don't use up the foobar.

    *   Bailout

         Bail out!  We ran out of foobar!

    *   Unknown

         ... yo, this ain't TAP! ...

    Each result fetched is a result object of a different type. There are common methods to each
    result object and different types may have methods unique to their type. Sometimes a type method
    may be overridden in a subclass, but its use is guaranteed to be identical.

  Common type methods
   "type"
    Returns the type of result, such as "comment" or "test".

   "as_string"
    Prints a string representation of the token. This might not be the exact output, however. Tests
    will have test numbers added if not present, TODO and SKIP directives will be capitalized and,
    in general, things will be cleaned up. If you need the original text for the token, see the
    "raw" method.

   "raw"
    Returns the original line of text which was parsed.

   "is_plan"
    Indicates whether or not this is the test plan line.

   "is_test"
    Indicates whether or not this is a test line.

   "is_comment"
    Indicates whether or not this is a comment. Comments will generally only appear in the TAP
    stream if STDERR is merged to STDOUT. See the "merge" option.

   "is_bailout"
    Indicates whether or not this is bailout line.

   "is_yaml"
    Indicates whether or not the current item is a YAML block.

   "is_unknown"
    Indicates whether or not the current line could be parsed.

   "is_ok"
      if ( $result->is_ok ) { ... }

    Reports whether or not a given result has passed. Anything which is not a test result returns
    true. This is merely provided as a convenient shortcut which allows you to do this:

     my $parser = TAP::Parser->new( { source => $source } );
     while ( my $result = $parser->next ) {
         # only print failing results
         print $result->as_string unless $result->is_ok;
     }

  "plan" methods
     if ( $result->is_plan ) { ... }

    If the above evaluates as true, the following methods will be available on the $result object.

   "plan"
      if ( $result->is_plan ) {
         print $result->plan;
      }

    This is merely a synonym for "as_string".

   "directive"
     my $directive = $result->directive;

    If a SKIP directive is included with the plan, this method will return it.

     1..0 # SKIP: why bother?

   "explanation"
     my $explanation = $result->explanation;

    If a SKIP directive was included with the plan, this method will return the explanation, if any.

  "pragma" methods
     if ( $result->is_pragma ) { ... }

    If the above evaluates as true, the following methods will be available on the $result object.

   "pragmas"
    Returns a list of pragmas each of which is a + or - followed by the pragma name.

  "comment" methods
     if ( $result->is_comment ) { ... }

    If the above evaluates as true, the following methods will be available on the $result object.

   "comment"
      if ( $result->is_comment ) {
          my $comment = $result->comment;
          print "I have something to say:  $comment";
      }

  "bailout" methods
     if ( $result->is_bailout ) { ... }

    If the above evaluates as true, the following methods will be available on the $result object.

   "explanation"
      if ( $result->is_bailout ) {
          my $explanation = $result->explanation;
          print "We bailed out because ($explanation)";
      }

    If, and only if, a token is a bailout token, you can get an "explanation" via this method. The
    explanation is the text after the mystical "Bail out!" words which appear in the tap output.

  "unknown" methods
     if ( $result->is_unknown ) { ... }

    There are no unique methods for unknown results.

  "test" methods
     if ( $result->is_test ) { ... }

    If the above evaluates as true, the following methods will be available on the $result object.

   "ok"
      my $ok = $result->ok;

    Returns the literal text of the "ok" or "not ok" status.

   "number"
      my $test_number = $result->number;

    Returns the number of the test, even if the original TAP output did not supply that number.

   "description"
      my $description = $result->description;

    Returns the description of the test, if any. This is the portion after the test number but
    before the directive.

   "directive"
      my $directive = $result->directive;

    Returns either "TODO" or "SKIP" if either directive was present for a test line.

   "explanation"
      my $explanation = $result->explanation;

    If a test had either a "TODO" or "SKIP" directive, this method will return the accompanying
    explanation, if present.

      not ok 17 - 'Pigs can fly' # TODO not enough acid

    For the above line, the explanation is *not enough acid*.

   "is_ok"
      if ( $result->is_ok ) { ... }

    Returns a boolean value indicating whether or not the test passed. Remember that for TODO tests,
    the test always passes.

    Note: this was formerly "passed". The latter method is deprecated and will issue a warning.

   "is_actual_ok"
      if ( $result->is_actual_ok ) { ... }

    Returns a boolean value indicating whether or not the test passed, regardless of its TODO
    status.

    Note: this was formerly "actual_passed". The latter method is deprecated and will issue a
    warning.

   "is_unplanned"
      if ( $test->is_unplanned ) { ... }

    If a test number is greater than the number of planned tests, this method will return true.
    Unplanned tests will *always* return false for "is_ok", regardless of whether or not the test
    "has_todo" (see TAP::Parser::Result::Test for more information about this).

   "has_skip"
      if ( $result->has_skip ) { ... }

    Returns a boolean value indicating whether or not this test had a SKIP directive.

   "has_todo"
      if ( $result->has_todo ) { ... }

    Returns a boolean value indicating whether or not this test had a TODO directive.

    Note that TODO tests *always* pass. If you need to know whether or not they really passed, check
    the "is_actual_ok" method.

   "in_todo"
      if ( $parser->in_todo ) { ... }

    True while the most recent result was a TODO. Becomes true before the TODO result is returned
    and stays true until just before the next non- TODO test is returned.

TOTAL RESULTS
    After parsing the TAP, there are many methods available to let you dig through the results and
    determine what is meaningful to you.

  Individual Results
    These results refer to individual tests which are run.

   "passed"
     my @passed = $parser->passed; # the test numbers which passed
     my $passed = $parser->passed; # the number of tests which passed

    This method lets you know which (or how many) tests passed. If a test failed but had a TODO
    directive, it will be counted as a passed test.

   "failed"
     my @failed = $parser->failed; # the test numbers which failed
     my $failed = $parser->failed; # the number of tests which failed

    This method lets you know which (or how many) tests failed. If a test passed but had a TODO
    directive, it will NOT be counted as a failed test.

   "actual_passed"
     # the test numbers which actually passed
     my @actual_passed = $parser->actual_passed;

     # the number of tests which actually passed
     my $actual_passed = $parser->actual_passed;

    This method lets you know which (or how many) tests actually passed, regardless of whether or
    not a TODO directive was found.

   "actual_ok"
    This method is a synonym for "actual_passed".

   "actual_failed"
     # the test numbers which actually failed
     my @actual_failed = $parser->actual_failed;

     # the number of tests which actually failed
     my $actual_failed = $parser->actual_failed;

    This method lets you know which (or how many) tests actually failed, regardless of whether or
    not a TODO directive was found.

   "todo"
     my @todo = $parser->todo; # the test numbers with todo directives
     my $todo = $parser->todo; # the number of tests with todo directives

    This method lets you know which (or how many) tests had TODO directives.

   "todo_passed"
     # the test numbers which unexpectedly succeeded
     my @todo_passed = $parser->todo_passed;

     # the number of tests which unexpectedly succeeded
     my $todo_passed = $parser->todo_passed;

    This method lets you know which (or how many) tests actually passed but were declared as "TODO"
    tests.

   "todo_failed"
      # deprecated in favor of 'todo_passed'.  This method was horribly misnamed.

    This was a badly misnamed method. It indicates which TODO tests unexpectedly succeeded. Will now
    issue a warning and call "todo_passed".

   "skipped"
     my @skipped = $parser->skipped; # the test numbers with SKIP directives
     my $skipped = $parser->skipped; # the number of tests with SKIP directives

    This method lets you know which (or how many) tests had SKIP directives.

  Pragmas
   "pragma"
    Get or set a pragma. To get the state of a pragma:

      if ( $p->pragma('strict') ) {
          # be strict
      }

    To set the state of a pragma:

      $p->pragma('strict', 1); # enable strict mode

   "pragmas"
    Get a list of all the currently enabled pragmas:

      my @pragmas_enabled = $p->pragmas;

  Summary Results
    These results are "meta" information about the total results of an individual test program.

   "plan"
     my $plan = $parser->plan;

    Returns the test plan, if found.

   "good_plan"
    Deprecated. Use "is_good_plan" instead.

   "is_good_plan"
      if ( $parser->is_good_plan ) { ... }

    Returns a boolean value indicating whether or not the number of tests planned matches the number
    of tests run.

    Note: this was formerly "good_plan". The latter method is deprecated and will issue a warning.

    And since we're on that subject ...

   "tests_planned"
      print $parser->tests_planned;

    Returns the number of tests planned, according to the plan. For example, a plan of '1..17' will
    mean that 17 tests were planned.

   "tests_run"
      print $parser->tests_run;

    Returns the number of tests which actually were run. Hopefully this will match the number of
    "$parser->tests_planned".

   "skip_all"
    Returns a true value (actually the reason for skipping) if all tests were skipped.

   "start_time"
    Returns the wall-clock time when the Parser was created.

   "end_time"
    Returns the wall-clock time when the end of TAP input was seen.

   "start_times"
    Returns the CPU times (like "times" in perlfunc when the Parser was created.

   "end_times"
    Returns the CPU times (like "times" in perlfunc when the end of TAP input was seen.

   "has_problems"
      if ( $parser->has_problems ) {
          ...
      }

    This is a 'catch-all' method which returns true if any tests have currently failed, any TODO
    tests unexpectedly succeeded, or any parse errors occurred.

   "version"
      $parser->version;

    Once the parser is done, this will return the version number for the parsed TAP. Version numbers
    were introduced with TAP version 13 so if no version number is found version 12 is assumed.

   "exit"
      $parser->exit;

    Once the parser is done, this will return the exit status. If the parser ran an executable, it
    returns the exit status of the executable.

   "wait"
      $parser->wait;

    Once the parser is done, this will return the wait status. If the parser ran an executable, it
    returns the wait status of the executable. Otherwise, this merely returns the "exit" status.

  "ignore_exit"
      $parser->ignore_exit(1);

    Tell the parser to ignore the exit status from the test when determining whether the test
    passed. Normally tests with non-zero exit status are considered to have failed even if all
    individual tests passed. In cases where it is not possible to control the exit value of the test
    script use this option to ignore it.

   "parse_errors"
     my @errors = $parser->parse_errors; # the parser errors
     my $errors = $parser->parse_errors; # the number of parser_errors

    Fortunately, all TAP output is perfect. In the event that it is not, this method will return
    parser errors. Note that a junk line which the parser does not recognize is "not" an error. This
    allows this parser to handle future versions of TAP. The following are all TAP errors reported
    by the parser:

    *   Misplaced plan

        The plan (for example, '1..5'), must only come at the beginning or end of the TAP output.

    *   No plan

        Gotta have a plan!

    *   More than one plan

         1..3
         ok 1 - input file opened
         not ok 2 - first line of the input valid # todo some data
         ok 3 read the rest of the file
         1..3

        Right. Very funny. Don't do that.

    *   Test numbers out of sequence

         1..3
         ok 1 - input file opened
         not ok 2 - first line of the input valid # todo some data
         ok 2 read the rest of the file

        That last test line above should have the number '3' instead of '2'.

        Note that it's perfectly acceptable for some lines to have test numbers and others to not
        have them. However, when a test number is found, it must be in sequence. The following is
        also an error:

         1..3
         ok 1 - input file opened
         not ok - first line of the input valid # todo some data
         ok 2 read the rest of the file

        But this is not:

         1..3
         ok  - input file opened
         not ok - first line of the input valid # todo some data
         ok 3 read the rest of the file

   "get_select_handles"
    Get an a list of file handles which can be passed to "select" to determine the readiness of this
    parser.

   "delete_spool"
    Delete and return the spool.

      my $fh = $parser->delete_spool;

CALLBACKS
    As mentioned earlier, a "callback" key may be added to the "TAP::Parser" constructor. If
    present, each callback corresponding to a given result type will be called with the result as
    the argument if the "run" method is used. The callback is expected to be a subroutine reference
    (or anonymous subroutine) which is invoked with the parser result as its argument.

     my %callbacks = (
         test    => \&test_callback,
         plan    => \&plan_callback,
         comment => \&comment_callback,
         bailout => \&bailout_callback,
         unknown => \&unknown_callback,
     );

     my $aggregator = TAP::Parser::Aggregator->new;
     for my $file ( @test_files ) {
         my $parser = TAP::Parser->new(
             {
                 source    => $file,
                 callbacks => \%callbacks,
             }
         );
         $parser->run;
         $aggregator->add( $file, $parser );
     }

    Callbacks may also be added like this:

     $parser->callback( test => \&test_callback );
     $parser->callback( plan => \&plan_callback );

    The following keys allowed for callbacks. These keys are case-sensitive.

    *   "test"

        Invoked if "$result->is_test" returns true.

    *   "version"

        Invoked if "$result->is_version" returns true.

    *   "plan"

        Invoked if "$result->is_plan" returns true.

    *   "comment"

        Invoked if "$result->is_comment" returns true.

    *   "bailout"

        Invoked if "$result->is_unknown" returns true.

    *   "yaml"

        Invoked if "$result->is_yaml" returns true.

    *   "unknown"

        Invoked if "$result->is_unknown" returns true.

    *   "ELSE"

        If a result does not have a callback defined for it, this callback will be invoked. Thus, if
        all of the previous result types are specified as callbacks, this callback will *never* be
        invoked.

    *   "ALL"

        This callback will always be invoked and this will happen for each result after one of the
        above callbacks is invoked. For example, if Term::ANSIColor is loaded, you could use the
        following to color your test output:

         my %callbacks = (
             test => sub {
                 my $test = shift;
                 if ( $test->is_ok && not $test->directive ) {
                     # normal passing test
                     print color 'green';
                 }
                 elsif ( !$test->is_ok ) {    # even if it's TODO
                     print color 'white on_red';
                 }
                 elsif ( $test->has_skip ) {
                     print color 'white on_blue';

                 }
                 elsif ( $test->has_todo ) {
                     print color 'white';
                 }
             },
             ELSE => sub {
                 # plan, comment, and so on (anything which isn't a test line)
                 print color 'black on_white';
             },
             ALL => sub {
                 # now print them
                 print shift->as_string;
                 print color 'reset';
                 print "\n";
             },
         );

    *   "EOF"

        Invoked when there are no more lines to be parsed. Since there is no accompanying
        TAP::Parser::Result object the "TAP::Parser" object is passed instead.

TAP GRAMMAR
    If you're looking for an EBNF grammar, see TAP::Parser::Grammar.

BACKWARDS COMPATIBILITY
    The Perl-QA list attempted to ensure backwards compatibility with Test::Harness. However, there
    are some minor differences.

  Differences
    *   TODO plans

        A little-known feature of Test::Harness is that it supported TODO lists in the plan:

         1..2 todo 2
         ok 1 - We have liftoff
         not ok 2 - Anti-gravity device activated

        Under Test::Harness, test number 2 would *pass* because it was listed as a TODO test on the
        plan line. However, we are not aware of anyone actually using this feature and hard-coding
        test numbers is discouraged because it's very easy to add a test and break the test number
        sequence. This makes test suites very fragile. Instead, the following should be used:

         1..2
         ok 1 - We have liftoff
         not ok 2 - Anti-gravity device activated # TODO

    *   'Missing' tests

        It rarely happens, but sometimes a harness might encounter 'missing tests:

         ok 1
         ok 2
         ok 15
         ok 16
         ok 17

        Test::Harness would report tests 3-14 as having failed. For the "TAP::Parser", these tests
        are not considered failed because they've never run. They're reported as parse failures
        (tests out of sequence).

SUBCLASSING
    If you find you need to provide custom functionality (as you would have using
    Test::Harness::Straps), you're in luck: "TAP::Parser" and friends are designed to be easily
    plugged-into and/or subclassed.

    Before you start, it's important to know a few things:

    1 All "TAP::*" objects inherit from TAP::Object.

    2 Many "TAP::*" classes have a *SUBCLASSING* section to guide you.

    3 Note that "TAP::Parser" is designed to be the central "maker" - ie: it is responsible for
      creating most new objects in the "TAP::Parser::*" namespace.

      This makes it possible for you to have a single point of configuring what subclasses should be
      used, which means that in many cases you'll find you only need to sub-class one of the
      parser's components.

      The exception to this rule are *SourceHandlers* & *Iterators*, but those are both created with
      customizable *IteratorFactory*.

    4 By subclassing, you may end up overriding undocumented methods. That's not a bad thing per se,
      but be forewarned that undocumented methods may change without warning from one release to the
      next - we cannot guarantee backwards compatibility. If any *documented* method needs changing,
      it will be deprecated first, and changed in a later release.

  Parser Components
   Sources
    A TAP parser consumes input from a single *raw source* of TAP, which could come from anywhere (a
    file, an executable, a database, an IO handle, a URI, etc..). The source gets bundled up in a
    TAP::Parser::Source object which gathers some meta data about it. The parser then uses a
    TAP::Parser::IteratorFactory to determine which TAP::Parser::SourceHandler to use to turn the
    raw source into a stream of TAP by way of "Iterators".

    If you simply want "TAP::Parser" to handle a new source of TAP you probably don't need to
    subclass "TAP::Parser" itself. Rather, you'll need to create a new TAP::Parser::SourceHandler
    class, and just plug it into the parser using the *sources* param to "new". Before you start
    writing one, read through TAP::Parser::IteratorFactory to get a feel for how the system works
    first.

    If you find you really need to use your own iterator factory you can still do so without
    sub-classing "TAP::Parser" by setting "iterator_factory_class".

    If you just need to customize the objects on creation, subclass TAP::Parser and override
    "make_iterator_factory".

    Note that "make_source" & "make_perl_source" have been *DEPRECATED* and are now removed.

   Iterators
    A TAP parser uses *iterators* to loop through the *stream* of TAP read in from the *source* it
    was given. There are a few types of Iterators available by default, all sub-classes of
    TAP::Parser::Iterator. Choosing which iterator to use is the responsibility of the *iterator
    factory*, though it simply delegates to the *Source Handler* it uses.

    If you're writing your own TAP::Parser::SourceHandler, you may need to create your own iterators
    too. If so you'll need to subclass TAP::Parser::Iterator.

    Note that "make_iterator" has been *DEPRECATED* and is now removed.

   Results
    A TAP parser creates TAP::Parser::Results as it iterates through the input *stream*. There are
    quite a few result types available; choosing which class to use is the responsibility of the
    *result factory*.

    To create your own result types you have two options:

    option 1
      Subclass TAP::Parser::Result and register your new result type/class with the default
      TAP::Parser::ResultFactory.

    option 2
      Subclass TAP::Parser::ResultFactory itself and implement your own TAP::Parser::Result creation
      logic. Then you'll need to customize the class used by your parser by setting the
      "result_factory_class" parameter. See "new" for more details.

    If you need to customize the objects on creation, subclass TAP::Parser and override
    "make_result".

   Grammar
    TAP::Parser::Grammar is the heart of the parser. It tokenizes the TAP input *stream* and
    produces results. If you need to customize its behaviour you should probably familiarize
    yourself with the source first. Enough lecturing.

    Subclass TAP::Parser::Grammar and customize your parser by setting the "grammar_class"
    parameter. See "new" for more details.

    If you need to customize the objects on creation, subclass TAP::Parser and override
    "make_grammar"
