Rtruckboris: Ruby bindings for the truckboris library

With rtruckboris, you can easily parse C headers files in pure Ruby.

#!/usr/bin/env ruby

require 'rtruckboris'

parser = Rtruckboris::HeaderParser.new("a_file.h", ["/usr/include"])
parser.parse

functions = parser.functions
puts "Functions number : #{functions.size}"
functions.each do |f|
  puts "Name : #{f.name}"
  puts "Return : #{f.return.name}"
  params = f.parameters
  puts "\t #{params.size.to_s} parameters :"
  params.each do |p|
    puts "\t\t#{p.type.name}  #{p.name}"
    if(!p.type.is_canonical)
      puts "\t\t\t#{p.type.canonical_type.name}"
    end
  end
end

functions.each do |f|
  puts f.raw(parser.source_manager,parser.lang_opts)
end

Resolve dependencies and Install

Dependencies

rtruckboris is a ruby extension for the truckboris library so you need to install it (https://github.com/cedlemo/truckboris) and its dependencies (LLVM and Clang >= 3.4 to 3.8).

You will need to install :

Ruby
Rake-compiler
swig

Install

When this is done, clone this repository with:

git clone https://github.com/cedlemo/rtruckboris

First (re)generate the extension source code via swig with:

rake swig

Then create the gem for your platform:

gem build rtruckboris.gemspec

You can now install the rtruckboris gem with:

gem install rtruckboris-x.x.x.gem

Usage

a lot of examples can be found in the test lib. I use those files when I test truckboris functionnalities you have two ways to try them:

Without installing rtuckboris

rake swig rake compile Then you can use each files in the directory (be sure to be in this directory in order to launch those files.

After installing rtruckboris as a gem

Just modify the require line: require File.dirname(FILE) + "/../lib/rtruckboris/rtruckboris"

with

require 'rtruckboris'
