2011 Call for grant proposals

Call for grant proposals has been closed.

Selection Result

The following two projects have been selected from 16 proposals by the grant committee.

Ruby reference manual for you, me and everyone

Applicant: Yutaka Hara

Ruby has API documentation only in English and Japanese, and their works are going separately. This project aims to provide a system for Ruby’s API documentation with a model “one central documentation (English) and its translations to other languages” to make it easier to start translating to a new language.


Applicant: Martin Boßlet

The goal of the krypt project is to provide a platform- and library-independent cryptography API for Ruby. Not only C-based Ruby implementations should be able to benefit from it, but there will also be an implementation for JRuby.

The focus is on providing most of the features in Ruby, while additionally offering the possibility to integrate OS- or language-specific native libraries to implement cryptographic primitives. The milestones of the grant period cover two of the major building blocks of krypt: a streaming ASN.1 parser and a Ruby DSL for parsing and encoding arbitrary ASN.1 objects - the basic building blocks of most cryptographic protocols. There will be 2 separate implementations for Java- and C-based Rubies to guarantee maximum performance, offering a Ruby interface that will be used throughout the library to implement higher-level functionality. Documentation includes RDoc, general interface documentation in the project wiki, as well as a technical specification in the form of RSpec specs.


The Ruby Association is looking to give grants for development projects related to Ruby implementations, libraries and frameworks, including projects that improve existing software.

If you have a good idea, please submit a proposal. However, please note that we do not intend to fund development projects of Ruby applications for specific purposes because the aim of this grant is to improve Ruby and its environment.
