NAME

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

VERSION

Version 3.23

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::Sources 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.
