Bad news. The server hosting The Ruby Toolbox went bust on the evening of June 7th. While I do have backups, the original source code is in a very outdated state so I currently don't feel it makes sense to try and get it running again.

For the time being, here is a very stripped down version of the Ruby Toolbox's contents.

Update June 13th: I'd like to invite you to join the discussion on the future of the Toolbox on github. You can also get in touch directly on Twitter.

Ocra

Crate

Crate is a developer tool to help package up your application as a custom static build of the ruby interpreter plus all dependent binary extensions. All the pure ruby code (the ruby application, the ruby stdlib, etc ) is packed into one or more SQLite databases. The final distributable pieces are a single executable and a few SQLite databases which can be then wrapped up appropriately as an OS X App; a self extracting executable for Windows; a shar archive, rpm or tarball for Unixes.
