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 SUPPORTED FEATURES "use?" useflag? ( children ) Maps to a "::Node::Group::Use" "!use?" !useflag? ( children ) Maps to a "::Node::Group::NotUse" "|| ()" || ( children ) Maps to "::Node::Group::Or" "()" ( children ) Maps to "::Node::Group::And" AUTHOR Kent Fredric COPYRIGHT AND LICENSE This software is copyright (c) 2013 by Kent Fredric .
