ffi-generator by Andrea Fazzi http://github.com/remogatto/ffi-generator/tree/master

== DESCRIPTION:

ffi-generator is a ruby-ffi wrapper code generator based on SWIG interface files.

ffi-generator is able to traverse a XML parse tree file generated by SWIG and to produce a ruby-ffi interface file from it.

ffi-generator is shipped with a command line tool (ffi-gen) and a rake task that automates the code generation process.

ffi-generator XML capabilities are provided by nokogiri.

== FEATURES/PROBLEMS:

• The program is able to generate:
  • all C native types
  • #define constants
  • typedefs
  • struct, union, array and enum types
  • callbacks (pointers to functions)
• Naive indentation of the generated code

== SYNOPSIS:

From command line:

ffi-gen mylib.xml mylib.rb

From a Rakefile:

require 'ffi-generator' FFI::Generator::Task.new :input_fn => 'my_interface_dir/*.i' output_dir => 'my_output_dir'

== REQUIREMENTS:

• rake >= 0.8.3
• nokogiri >= 1.1.1

== DOWNLOAD/INSTALL:

To download and install the gem from github:

[sudo] gem sources -a http://gems.github.com [sudo] gem install remogatto-ffi-generator

To download the develpment trunk:

git clone git://github.com/remogatto/ffi-generator.git

== EXAMPLES:

See the examples in examples/ folder.

libc.i is an interface file containing some excerpt of libc functions.

wiiuse.i is a enough complex example of a C header file interface. It reproduces the content of wiiuse.h, the header file of the wiiuse library. wiiuse is a C library that handles the connection with Nintendo Wiimote devices. The interface file is almost a mere copy/paste from the original header file.

== QUICK START:

git clone git://github.com/remogatto/ffi-generator.git sudo apt-get install swig sudo gem install nokogiri rake cd ffi-generator/examples && rake ffi:generate
