Parse::Eyapp uses and modifies all the files in the Parse::Yapp 1.06 distribution. This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself, either Perl version 5.6 or, at your option, any later version of Perl 5 you may have available. IMPORTANT NOTES The main source of documentation is Parse::Eyapp (Reference guide). Have a look at the tests, they can help you. Not all the examples in the examples/ directory work. The eyapp frontend has its own documentation using either 'perldoc eyapp' or (on systems with man pages) 'man eyapp'. The trereg frontend to Parse::Eyapp::Treeregexp has its own documentation using either 'perldoc treereg' or (on systems with man pages) 'man treereg'. Any help on improving those documentations is very welcome. DESCRIPTION Parse::Eyapp (Extended yapp) is a collection of modules that extends Francois Desarmenien Parse::Yapp. Eyapp extends yacc/yapp syntax with functionalities like named attributes, EBNF-like expressions, modifiable default action, automatic syntax tree building, semi-automatic abstract syntax tree building, translation schemes, tree regular expressions, tree transformations, scope analysis, support, directed acyclic graphs and a few more. REQUIREMENTS Requires Perl v5.6 or higher You need the following modules: List::Util Data::Dumper Pod::Usage The last three belong to the core of recent Perl distributions. Some of the tests make use of: Test::Exception Test::Warning Test::Pod The tests related with those modules are skipped if you haven't installed those modules. If you decided to install Test::Warn be aware that Test::Warn depends on Array::Compare. My experience is that you must install Array::Compare by hand first (i.e. perl Makefile.PL; make; make test; make install) and then go to install Test::Warn. INSTALLATION perl Makefile.PL make make test make install LEARNING TO USE IT - Make a local copy of the examples/ directory in this distribution - Probably it will be also a good idea to make a copy of the tests in the t/ directory. They also illustrate the use of Eyapp - Get the pdf files in http://nereida.deioc.ull.es/~pl/perlexamples/Eyapp.pdf - Print Eyapp.pdf. WARRANTY This software comes with absolutely NO WARRANTY of any kind. I just hope it can be useful. FEEDBACK Send feedback, comments and bugs to: William N.
