Installing Ruby documentation locally with rvm

rvm docs generate-ri

Once installed you can do things at the command line like:

ri File

Which will print all the documentation for the file class.

I have a co-worker that will admonish you for not having ruby documentation close at hand (read: locally). I mean, what if you’re deep in the Pensylvannia hills on a 1G connection and you need some help with the http api?
