NAME
    TAP::Parser::Source - a TAP source & meta data about it

VERSION
    Version 3.43

SYNOPSIS
      use TAP::Parser::Source;
      my $source = TAP::Parser::Source->new;
      $source->raw( \'reference to raw TAP source' )
             ->config( \%config )
             ->merge( $boolean )
             ->switches( \@switches )
             ->test_args( \@args )
             ->assemble_meta;

      do { ... } if $source->meta->{is_file};
      # see assemble_meta for a full list of data available

DESCRIPTION
    A TAP *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. "TAP::Parser::Source"s encapsulate these *raw*
    sources, and provide some useful meta data about them. They are used by
    TAP::Parser::SourceHandlers, which do whatever is required to produce &
    capture a stream of TAP from the *raw* source, and package it up in a
    TAP::Parser::Iterator for the parser to consume.

    Unless you're writing a new TAP::Parser::SourceHandler, a plugin or
    subclassing TAP::Parser, you probably won't need to use this module
    directly.

METHODS
  Class Methods
   "new"
     my $source = TAP::Parser::Source->new;

    Returns a new "TAP::Parser::Source" object.

  Instance Methods
   "raw"
      my $raw = $source->raw;
      $source->raw( $some_value );

    Chaining getter/setter for the raw TAP source. This is a reference, as
    it may contain large amounts of data (eg: raw TAP).

   "meta"
      my $meta = $source->meta;
      $source->meta({ %some_value });

    Chaining getter/setter for meta data about the source. This defaults to
    an empty hashref. See "assemble_meta" for more info.

   "has_meta"
    True if the source has meta data.

   "config"
      my $config = $source->config;
      $source->config({ %some_value });

    Chaining getter/setter for the source's configuration, if any has been
    provided by the user. How it's used is up to you. This defaults to an
    empty hashref. See "config_for" for more info.

   "merge"
      my $merge = $source->merge;
      $source->config( $bool );

    Chaining getter/setter for the flag that dictates whether STDOUT and
    STDERR should be merged (where appropriate). Defaults to undef.

   "switches"
      my $switches = $source->switches;
      $source->config([ @switches ]);

    Chaining getter/setter for the list of command-line switches that should
    be passed to the source (where appropriate). Defaults to undef.

   "test_args"
      my $test_args = $source->test_args;
      $source->config([ @test_args ]);

    Chaining getter/setter for the list of command-line arguments that
    should be passed to the source (where appropriate). Defaults to undef.

   "assemble_meta"
      my $meta = $source->assemble_meta;

    Gathers meta data about the "raw" source, stashes it in "meta" and
    returns it as a hashref. This is done so that the
    TAP::Parser::SourceHandlers don't have to repeat common checks.
    Currently this includes:

        is_scalar => $bool,
        is_hash   => $bool,
        is_array  => $bool,

        # for scalars:
        length => $n
        has_newlines => $bool

        # only done if the scalar looks like a filename
        is_file => $bool,
        is_dir  => $bool,
        is_symlink => $bool,
        file => {
            # only done if the scalar looks like a filename
            basename => $string, # including ext
            dir      => $string,
            ext      => $string,
            lc_ext   => $string,
            # system checks
            exists  => $bool,
            stat    => [ ... ], # perldoc -f stat
            empty   => $bool,
            size    => $n,
            text    => $bool,
            binary  => $bool,
            read    => $bool,
            write   => $bool,
            execute => $bool,
            setuid  => $bool,
            setgid  => $bool,
            sticky  => $bool,
            is_file => $bool,
            is_dir  => $bool,
            is_symlink => $bool,
            # only done if the file's a symlink
            lstat      => [ ... ], # perldoc -f lstat
            # only done if the file's a readable text file
            shebang => $first_line,
        }

      # for arrays:
      size => $n,

   "shebang"
    Get the shebang line for a script file.

      my $shebang = TAP::Parser::Source->shebang( $some_script );

    May be called as a class method

   "config_for"
      my $config = $source->config_for( $class );

    Returns "config" for the $class given. Class names may be fully
    qualified or abbreviated, eg:

      # these are equivalent
      $source->config_for( 'Perl' );
      $source->config_for( 'TAP::Parser::SourceHandler::Perl' );

    If a fully qualified $class is given, its abbreviated version is checked
    first.
