Here you'll find a non-exhaustive list of my open-source projects (past and present):

RubyJS - Efficient Ruby to Javascript Compilation
Description

RubyJS is an efficient Ruby to Javascript compiler. It allows a static subset of Ruby to be compiled to Javascript and also allows the full set of meta-programming to be applied to the program before compilation.

I gave a talk about RubyJS at the international Ruby Conference RubyConf in 2007. The Slides and Recordings of my Talk.

Status
Usable. Active.
Wee - Component Oriented Web Framework
Description
Wee is a light-weight, very high-level and modern stateful web-framework that makes Web engineering easy. It mainly inherits many ideas and features from Seaside2. It was developed purely from ideas and lots of discussions with Avi Bryant (the author of Seaside). Some key features:
  • Reusable components
  • Backtracking
  • Stateful
  • Powerful programmatic HTML generation
  • Optional continuation-based
Status
Stable. No further development.
Ruby/DBI - Database Independent Interface
Description
A database independent interface to relational databases similar to Perl's DBI but for Ruby. Supported databases include: DB2, Oracle 7-9i, PostgreSQL, MySQL, FrontBase, ODBC, ADO, Interbase, mSQL, SQLite, SQLRelay, Remote/Proxy (TCP/IP).
Status
No longer maintained by me. Maintained by others.
XML-RPC for Ruby
Description
XML-RPC provides remote procedure calls (RPCs) over HTTP using XML as transmission format. This is an implementation for Ruby. XML-RPC is like SOAP but much easier. For more information see the XML-RPC specification.
Status
Ships with Ruby. Development has stopped.
XSLT for Ruby
Description
XSLT4R is an EXtensible Stylesheet Language for Transformations (or XSLT in short) processor written in pure Ruby. It's extensible through Ruby methods.
Status
Prototype state (weekend hack)
ruby-ggi
Description
GGI (General Graphics Interface) bindings for Ruby.
Status
Usable. Development stalled
Guugelhupf
Description

Project G.H. or Guugelhupf is my implementation of a simple search engine (index generation + query) in MLton (a whole program optimizing Standard ML compiler). It is the result from a study task in computer science at the 4th semester.

Have a look at some assorted colorized source codes. It was my first (and last) big program written in ML.

Status
Finished.
