Problem with ri or me?

Ruby
1

Hello –

I just installed Ruby a couple of days ago, and I have been going
through
tutorials, etc. One thing I can’t explain is that ri doesn’t seem to
work
on my system. I am running Ruby 1.8.6 on XP. I am trying to run ri
through
irb 0.9.5. (Both things are what I got when I did the simple install a
few
days ago.)

If I enter ri, I get something like “undefined method `ri’ for
main:Object
from (irb):4”

What am I doing wrong?

Thanks

Dave Miller

You run ri from the command line, not from within irb.

Welcome to Ruby.

ri is a command line tool.

I had the same confusion when I first got started!

In irb, you can type the object_name.methods
dot methods will give you a list of methods for the object.
This is a good thing to keep in mind. It’s one example of why irb is
so useful. Rather than combing through documentation all the time,
you can ask the object directly!
