Just after RailsConf last summer, Luke Redpath introduced plugin packs to the world. Not long after he implemented the idea, he rolled it into the Rails Plugin Tool. It's a fantastic idea, allowing you to install an entire list of plugins in one shot. Now the idea has been kicked up a notch.
I mentioned previously that I would be making the favorites feature at the Rails plugin directory a little more handy, and now I have. When you log in to your account at the directory and view your favorite plugins, you'll now see instructions on how to use the plugin pack installation feature of RaPT with your favorites. In short, once you create your list of favorite plugins at the site, you can then install all of those plugins with one RaPT command.
Try it out. It's fun. :)
