== DESCRIPTION:

Racc is a LALR(1) parser generator. It is written in Ruby itself, and generates Ruby program.

NOTE: Ruby 1.8.x comes with Racc runtime module. You can run your parsers generated by racc 1.4.x out of the box.

== Requirement

  • Ruby 1.8.x or later.

== Installation

gem install:

$ gem install racc

setup.rb install:

Type this in the top directory of the extracted archive:

$ ruby setup.rb config
$ ruby setup.rb setup

($ su) # ruby setup.rb install

You can install Racc into your favorite directory by giving options to setup.rb. e.g.

$ ruby setup.rb config --prefix=/usr

For details, try "ruby setup.rb --help".

If you don't have C Compiler


You can install Racc without C compilers. Type following command in config phase.

$ ruby setup.rb config --without-ext

== Testing Racc

Racc comes with simple calculator. To compile this, on shell:

  $ racc -o calc calc.y

This process costs few seconds (or less). Then type:

  $ ruby calc

... Does it works? For details of Racc, see HTML documents placed under 'doc.en/' and sample grammer files under 'sample/'.

== License

Racc is distributed under the same terms of ruby. (see the file COPYING). Note that you do NOT need to follow ruby license for your own parser (racc outputs). You can distribute those files under any licenses you want.

== Bug Reports

Any kind of bug reports are welcome. If you find a bug of Racc, please email me. Your grammer file, debug output genereted by "racc -g", are helpful.
