# NAME

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

# VERSION

Version 3.48

# 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.
