Language-GolfScript v0.04 ------------------------- Language::GolfScript is a Pure Perl implementation of the GolfScript programming language. GolfScript is a stack oriented esoteric language aimed at solving problems with short programs. The original GolfScript implementation was by Darren Smith in the Ruby programming language. More information about the GolfScript language and its Ruby implementation are available at http://www.golfscript.com/golfscript/ The Language::GolfScript package contains the full GolfScript implementation. This module also installs a package simply called G which can wrap a source code file into the Language::GolfScript parser. This will allow you to evaluate GolfScript code from the command line. That is, perl -MG my_golfscript_file.gs should produce the same output as ruby golfscript.rb my_golfscript_file.gs except it takes 10 fewer characters! DEBUGGING GOLFSCRIPT The Language::GolfScript language has logging facilities to show you what the GolfScript interpreter is doing and to help test and debug your GolfScript code. To use debugging, pass the "debug" or "verbose" parameters to either the Language::GolfScript or G modules: $ perl -MG -e "4 3+" 7 $ perl -MG=debug -e "4 3+" Stack initialized: Evaluating: 4 3+ Parsing: "4" push [1]: 4 Parsing: " " Parsing: "3" push [2]: 3 Parsing: "+" pop [2]: 3 pop [1]: 4 push [1]: 7 Parsing: " " 7 $ perl -MG=verbose "4 3+" Stack initialized: Evaluating: 4 3+ Parsing: "4" push [1]: 4 STACK[0]: "" STACK[1]: 4 Parsing: " " Parsing: "3" push [2]: 3 STACK[0]: "" STACK[1]: 4 STACK[2]: 3 Parsing: "+" pop [2]: 3 STACK[0]: "" STACK[1]: 4 pop [1]: 4 STACK[0]: "" push [1]: 7 STACK[0]: "" STACK[1]: 7 Parsing: " " 7 INSTALLATION To install this module, run the following commands: perl Makefile.PL make make test make install If your system has a ruby interpreter and a copy of the ruby GolfScript implementation (available at http://www.golfscript.com/golfscript/golfscript.rb), there is an additional test you can perform that explicitly compares the Perl and Ruby GolfScript implementations against some sample GolfScript codes). Run GOLFSCRIPT_RB=/path/to/golfscript.rb perl t/ruby-compare.tt SUPPORT AND DOCUMENTATION After installing, you can find documentation for this module with the perldoc command. perldoc Language::GolfScript You can also look for information at: RT, CPAN's request tracker http://rt.cpan.org/NoAuth/Bugs.html?Dist=Language-GolfScript AnnoCPAN, Annotated CPAN documentation http://annocpan.org/dist/Language-GolfScript CPAN Ratings http://cpanratings.perl.org/d/Language-GolfScript Search CPAN http://search.cpan.org/dist/Language-GolfScript/ LICENSE AND COPYRIGHT Copyright (C) 2010 Marty O'Brien This program is free software; you can redistribute it and/or modify it under the terms of either: the GNU General Public License as published by the Free Software Foundation; or the Artistic License.
