What do I need to emerge to get ruby's "ri" documentation command? I did some web searches and it looks like there used to be a dev-ruby/ri package, but it doesn't seem to be there anymore

Silly question but have you emerged dev-lang/ruby ?

Ive seen the command "rdoc" mention as the documentation command for ruby. Its part of ruby.

Yeah, I definitely have ruby installed. And rdoc looks like javadoc, except for ruby, i.e. it produces documentation about code you write, not documentation about ruby functions

When I emerged ruby it installed a file called /usr/bin/ri18. There is also a symlink /usr/bin/ri that points to it. I'm using the latest stable ruby-1.8.4-r1. When I run "ri" on the command line I get:

Code: Select all

ri v1.0.1 - 20041108

Usage:

  ri [options]  [names...]

Display information on Ruby classes, modules, and methods.
Give the names of classes or methods to see their documentation.
Partial names may be given: if the names match more than
one entity, a list will be shown, otherwise details on
that entity will be displayed.

More gets printed out but I snipped the output.

Well I do have /usr/bin/ri but equery wont tell me where it came from

I just installed ruby,ruby-config, rubygems and rails the other day so it came from one of em.

Well.. ive only ever installed dev-lang/ruby and I have the same symlink /usr/bin/ri pointing to /usr/bin/ri18. Does that help?

Dang sneaky symlinks

Code: Select all

hielvc@tester ~ $ equery b /usr/bin/ri18

dev-lang/ruby-1.8.4.20060529 (/usr/bin/ri18)

Aaaahhh it's ri18 and not just ri. For some reason I don't have the symlink

Thanks for your help!
