Viewing RI in a web browser

I’m a big fan of the Firefox keyword search. For example I have keywords for LEO, Wikipedia and Man pages. Sometimes I want to look up API documentation in Ruby and typing ri camelize into the address bar and viewing the documentation as web page seems to be quite natural for me. So I wrote a quick and dirty cgi, which calls RI and outputs HTML.

Git Store - using Git as versioned data store in Ruby

GitStore is a small Ruby library, providing an easy interface to the version control system Git. It aims to use Git as a versioned data store much like the well known PStore. Basically GitStore checks out the repository into a in-memory representation, which can be modified and finally committed. In this way your data is stored in a folder structure and can be checked out and examined, but the application may access the data in a convenient hash-like way. This library is based on Grit, the main technology behind GitHub.

In the past Flex development on Emacs was not as it should be because of a missing Relax NG Schema, which is needed for nxml-mode to work properly. To improve the situation I developed a MXML Schema generator based on the XSD generator of Ali Mansuroglu. Now Emacs knows your Schema and can help you typing and validating MXML files.

Commenting system with lightweight JSON store

As I wrote this blog engine, the need for a commenting system arose and I reflected about a small and simple commenting system with just a flat file JSON store. This is my solution, which can be used on any static page on a server with PHP support.

Fast Auto-completion with Rails, Scriptaculous and JSON
