GraphViz2::Marpa Description

GraphViz2::Marpa is a Perl module that provides an Set::FA::Element-based lexer and a Marpa::XS-based parser for Graphviz (dot) graph definitions.Both the lexer and the parser must be run to parse the dot file. See "Scripts" for sample code.Demo lexer/parser output: http://savage.net.au/Perl-modules/html/graphviz2.marpa/index.html.State Transition Table: http://savage.net.au/Perl-modules/html/graphviz2.marpa/default.stt.html.Command line options and object attributes: http://savage.net.au/Perl-modules/html/graphviz2.marpa/code.attributes.html.My article on this set of modules: http://savage.net.au/Ron/html/graphviz2.marpa/Lexing.and.Parsing.with.Marpa.html.The Marpa grammar as an image: http://savage.net.au/Ron/html/graphviz2.marpa/Marpa.Grammar.svg.
