This weekend a fellow member of Rochester On Rails was nice enough to share an invite to Git Hub. Check out my account, I just published two little plugins I use all the time at work and at home when building Rails apps.
The first is Fixture Manager. This plugin adds a few methods to ActiveRecord classes allowing you to save database contents to YAML (either in your test/fixtures folder, or in cms/fixtures). The plugin also provides a few Rake tasks that wrap these methods as well as a simple static class (FixtureManager) giving you two options as to how you want to save and load your data.
The second is Rcov Task. This plugin contains almost no code, its a Rake task that simplifies running your test suite with rcov (and opening your browser if your in Mac OS X).
