NAME

Pod::Loom::Parser - Subclass Pod::Eventual for Pod::Loom

VERSION

This document describes version 0.05 of Pod::Loom::Parser, released March 23, 2014 as part of Pod-Loom version 0.08.

SYNOPSIS

  use Pod::Loom::Parser;

  my $parser = Pod::Loom::Parser->new( ['head1'] );
  $parser->read_file('lib/Foo/Bar.pm');
  my $collectedHash = $parser->collected;

  foreach my $block (@{ $collectedHash->{head1} }) {
    printf "---\n%s\n", $block;
  }

DESCRIPTION

Pod::Loom::Parser is a subclass of Pod::Eventual intended for use by Pod::Loom::Template. It breaks the POD into chunks based on a list of POD commands. Each chunk begins with one of the commands, and contains all the POD up until the next selected command.

The commands do not need to be valid POD commands. You can invent commands like =attr or =method.

METHODS

See Pod::Eventual for the read_handle, read_file, and read_string methods, which you use to feed POD into the parser.

new

  $parser = Pod::Loom::Parser->new(\@collect_commands);

Constructs a new Pod::Loom::Parser. You pass it an arrayref of the POD commands at which the POD should be chopped.

collected

  $hashRef = $parser->collected;

This returns the POD chunks that the document was chopped into. There is one entry for each of the @collect_commands that were passed to the constructor. The value is an arrayref of strings, one for each time that command appeared in the document. Each chunk contains all the text from the command up to (but not including) the command that started the next chunk. Chunks appear in document order.

If one of the commands did not appear in the document, its value will be an empty arrayref.

In addition, any POD targeted to a format matching /^Pod::Loom\b/ will be collected under the format name.

encoding

  $encoding = $parser->encoding;

This returns the encoding that was used for the document as an Encode object. If no encoding was explicitly defined, then the default Latin-1 encoding is returned.

groups

  $hashRef = $parser->groups;

This returns a hashref with one entry for each of the @collect_commands. Each value is a hashref whose keys are the categories used with that command. For example, if attr was a collected command, and the document contained these entries:

  =attr-foo attr1
  =attr-bar attr2
  =attr-foo attr3
  =attr attr4

then keys %{ $parser->groups->{attr} } would return bar and foo. (The =attr without a category does not get an entry in this hash.)

CONFIGURATION AND ENVIRONMENT

Pod::Loom::Parser requires no configuration files or environment variables.

DEPENDENCIES

Pod::Loom::Parser requires Pod::Eventual, which can be found on CPAN.
