R::DescriptionFile - R package DESCRIPTION file parser
version 0.005
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);
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.
