Build Status Code Climate

xdrgen is a code generator that takes XDR IDL files (.x files) as specfified in RFC 4506 and spits code out in various languages.

xdrgen requires ruby 2.1 or later to run.


Xdrgen is a very early project. Aside from the test fixtures in spec/fixtures, the only .x files that have been thrown at it are the .x files used for the stellar-core project.

Xdrgen presently supports three output languages: ruby, javacript, java, and golang:

  • ruby: complete support
  • javascript: complete support
  • java: complete support
  • golang: currently using a fork of go-xdr, but has complete support

Testing is very sparse, but will improve over time.

Usage as a binary

Xdrgen is a rubygem, compatible with ruby 2.1 or higher

$ gem install xdrgen

The command line:


Usage as a library

Add this line to your application's Gemfile:

gem 'xdrgen'

And then execute:

$ bundle

Example usage:

require 'xdrgen'

# create a compilation object, specifying your options

c = Xdrgen::Compilation.new(
  language: :ruby,
  namespace: "MyProgram::XDR"

# then run compile
