Golden

Golden is a development tool that makes it easier to wrap Go libraries for use in Ruby.

• Usage similar to the every day package manager
• Converts .go files to .so shared libraries
• Manages library exported function metadata in convenient JSON format
• Update notifications as of 0.6.1 - If you have a version prior to 0.6.1, update now to be notified when future updates are pushed to rubygems!

Building a slightly modified version of the "libsum.go" example

package main

import "C"

//export add
func add(a int, b int) int {
  return a + b
}
//export subtract
func subtract(a, b int) int { // as of 0.5.2 this shorthand parameter declaration is supported!
  return a - b
}


func main() {}

On the command line:

cd libsum
golden build libsum

cd ../golden-example
golden install libsum

Additionally, as of version 0.6.0, you can add libraries built manually or shared by another developer with the add command:

golden add path/to/library/directory

or

golden add path/to/library/directory/golden.json

Then, reference the library in your ruby project:

require "golden"

class GoldenExample
  def initialize
    libsum = Golden.require("libsum")
    puts libsum.add(1,2) #prints 3
  end
end

From rubygems:

[sudo] gem install golden

or from the git repository on github:

git clone git://github.com/gmikeska/golden.git
cd golden
bundle install
rake install
