TAP::Parser::Source

NAME

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

VERSION

Version 3.30

SYNOPSIS

  1.   use TAP::Parser::Source;
  2.   my $source = TAP::Parser::Source->new;
  3.   $source->raw( \'reference to raw TAP source' )
  4.          ->config( \%config )
  5.          ->merge( $boolean )
  6.          ->switches( \@switches )
  7.          ->test_args( \@args )
  8.          ->assemble_meta;
  10.   do { ... } if $source->meta->{is_file};
  11.   # 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 

  1.  my $source = TAP::Parser::Source->new;

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

Instance Methods

raw 

  1.   my $raw = $source->raw;
  2.   $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 

  1.   my $meta = $source->meta;
  2.   $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 

  1.   my $config = $source->config;
  2.   $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 

  1.   my $merge = $source->merge;
  2.   $source->config( $bool );

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

switches 

  1.   my $switches = $source->switches;
  2.   $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 

  1.   my $test_args = $source->test_args;
  2.   $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 

  1.   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:

  1.     is_scalar => $bool,
  2.     is_hash   => $bool,
  3.     is_array  => $bool,
  5.     # for scalars:
  6.     length => $n
  7.     has_newlines => $bool
  9.     # only done if the scalar looks like a filename
  10.     is_file => $bool,
  11.     is_dir  => $bool,
  12.     is_symlink => $bool,
  13.     file => {
  14.         # only done if the scalar looks like a filename
  15.         basename => $string, # including ext
  16.         dir      => $string,
  17.         ext      => $string,
  18.         lc_ext   => $string,
  19.         # system checks
  20.         exists  => $bool,
  21.         stat    => [ ... ], # perldoc -f stat
  22.         empty   => $bool,
  23.         size    => $n,
  24.         text    => $bool,
  25.         binary  => $bool,
  26.         read    => $bool,
  27.         write   => $bool,
  28.         execute => $bool,
  29.         setuid  => $bool,
  30.         setgid  => $bool,
  31.         sticky  => $bool,
  32.         is_file => $bool,
  33.         is_dir  => $bool,
  34.         is_symlink => $bool,
  35.         # only done if the file's a symlink
  36.         lstat      => [ ... ], # perldoc -f lstat
  37.         # only done if the file's a readable text file
  38.         shebang => $first_line,
  39.     }
  41.   # for arrays:
  42.   size => $n,

shebang

Get the shebang line for a script file.

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

May be called as a class method

config_for 

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

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

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

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