Unlocking Dark Secrets of rdoc/ri

So if you are not using the one-click installer (like anyone who compiles from source ) on Windows, ri/fxri is pretty useless. Not only don't your GEMs show, but anything else you've compiled doesn't either.

So how do you fix this?

Install it with rdoc -R from within the directory that has the .rb

# rdoc -R oniguruma.rb
    oniguruma.rb: mcc..........c....c.....

Make sure it is there with ri -l
