TAP::Parser::Source(3perl)       Perl Programmers Reference Guide      TAP::Parser::Source(3perl)



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

VERSION
       Version 3.30

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.
