NAME

R::DescriptionFile - R package DESCRIPTION file parser

VERSION

version 0.005

SYNOPSIS

use R::DescriptionFile;

my $desc1 = R::DescriptionFile->parse_file("DESCRIPTION");
print $desc1->{'Description'};
print $desc1->get('Depends');

my $desc2 = R::DescriptionFile->parse_text($desc_file_text);

DESCRIPTION

This module provides a parser for R's DESCRIPTION file which is shipped with a R package and contains meta data of the R package.

parse_file() or parse_text() returns object of this module class. It's a blessed hash, so fields of DESCRIPTION can be accessed via hash keys. There is also a get method which does the same thing.

For dependency fields like Depends, Suggests, Imports, LinkingTo, Enhances, they would be parsed to hashrefs of the form { pkgname => version_spec }, where version spec is either like (>= 1.0), or an empty string if it's not defined.

For list fields like URL, Additional_repositories, VignetteBuilder, they would be parsed to arrayrefs.
