# Racc

- i.loveruby.net/en/projects/racc/

- racc.rubyforge.org/

## 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.
    (*) make and C compiler.

## 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/'.
