FastRIEdit
FastRI is a faster replacement for ri which produces colorized output. It can be installed as follows:
sudo gem install fastri
The index can then be generated (or updated) using:
fastri-server -b
Local queries can then be run using commands like this:
qri String#chomp!
Instead of the standard:
ri String#chomp!
Note that in order to search the built-in classes you must explicitly install the documentation for them as described in "Getting ri working for built-in classes".
