With ffi-inliner you can run C code within your ruby script.

• Mix C snippets in your Ruby code and gulp it on the fly!

• It’s based on Ruby-FFI so the C code you inject is portable across Ruby implementations!

• Yep, it means that you can run it on JRuby too!

• Fast compilation through tcc

• But it can use the system’s compiler (e.g. gcc) on those platforms that don’t support tcc (e.g. OSX) or that don’t have it installed

require 'ffi-inliner'

module MyLib
  extend Inliner
  inline 'void say_hello(char* name) { printf("Hello, %s\n", name); }'
end

MyLib.say_hello('boys')

class Foo
  include MyLib
end

Foo.new.say_hello('foos')

For other hints see the examples/ folder or visit the wiki. For a “real” world example you may be interested to ffi-life.

• ffi >= 0.4.0

• gcc and/or tcc >= 0.9.25 (optional)

From rubyforge:

[sudo] gem install ffi-inliner

or from github:

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

Special thanks to:

• Ryan Davis for his inspiring RubyInline.

• Roger Pack for improving support for Windows platforms.
