cfis / ffi-clang

Ruby FFI bindings for libclang 3.4+.

FFI::Clang

A light-weight wrapper for Ruby exposing libclang. Works for libclang v3.4+.

Installation

Add this line to your application's Gemfile:

gem 'ffi-clang'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ffi-clang

Usage

Traverse the AST in the given file:

index = Index.new
translation_unit = index.parse_translation_unit("list.c")
cursor = translation_unit.cursor
cursor.visit_children do |cursor, parent|
	puts "#{cursor.kind} #{cursor.spelling.inspect}"
	
	next :recurse 
end

Library Version

Due to issues figuring out which library to use, we require you to manually specify it. For example, to run the tests, with MacPorts llvm/clang 3.4, use the following:

LLVM_CONFIG=llvm-config-mp-3.4 rake
