NAME

Gentoo::Dependency::AST - Convert a canonicalized (R|P|)DEPEND into an Abstract Syntax Tree

VERSION

version 0.001001

SYNOPSIS

Those familiar with Gentoo's ebuild format will be aware there are several variables that contain strings of dependencies that are required.

Namely: PDEPEND , RDEPEND and DEPEND

If you're a paludis user, one can get the canonicalized versions of these variables via

    cave show -c =cat/pkg-version

This module exists to parse those strings and provide a structured graph representing the dependencies:

    use Gentoo::Dependency::AST;

    my $node = Gentoo::Dependency::AST->parse_dep_string( $string_from_portage );

METHODS

parse_dep_string

    $class->parse_dep_string( $string )  # returns Gentoo::Dependency::AST::Node of some kind
