stellar / xdrgen

A code generator for XDR

Xdrgen

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

xdrgen requires ruby 2.1 or later to run.

Status

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 these output languages: ruby, javacript, java, golang, elixir and Python:

• ruby: complete support
• javascript: complete support
• java: complete support
• golang: currently using a fork of go-xdr, but has complete support
• rust: support is experimental. Default arms and floats are not supported.
• elixir: support is experimental as the SDK is in early development. Generated code requires :exdr in your deps
• C#: complete support
• Python: 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:

xdrgen [-o OUTPUT_DIR] [-l LANGUAGE] [-n NAMESPACE] [INPUT_FILES ...]

Language Specific Options

Rust

--rust-types-custom-str-impl: Used to specify a comma-separated list of type names that should not have string conversion code generated as it will be provided by custom implementations provided by the developer using the generated code.

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(
  ["MyProgram.x"],
  output_dir:"src/generated",
  language: :ruby,
  namespace: "MyProgram::XDR",
  options: {
    rust_types_custom_str_impl: [],
  },
)

# then run compile

c.compile
