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 1.05. 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 perl5.6 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.
