ruby_exts

Write Ruby extensions in Crystal. Built from this gist, based upon manastech/crystal_ruby.

Works with Crystal 0.20.0 and Ruby 2.3.1 on OSX El Capitan, though might work for other versions.

Work in progress.

Installation

Add this to your application's shard.yml:

dependencies:
  ruby_exts:
    github: spalladino/ruby_exts

Sample

Run an irb with the contents of samples/sample.cr with make irb:

$ make irb
irb(main):001:0> coco = Coco.new("3")
=> #<Coco:0x007ff0b3039840>
irb(main):002:0> coco.size
=> 3
irb(main):003:0> get "https://raw.githubusercontent.com/manastech/crystal_ruby/master/README.md"
=> "crystal_ruby\n============\n\nWrite Ruby extensions in Crystal. This is just a [Proof of Concept](http://en.wikipedia.org/wiki/Proof_of_concept).\n"

Usage

Coming soon.
