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
