comp.lang.ruby

using ri with gems

msoulier

6/30/2006 4:02:00 PM

When I install a new gem, it runs rdoc on the source to pull out docs
that are then available via the gem_server on localhost 8808. Being a
long-time Perl programmer, I want perldoc.

If I install say, Text::CSV from the CPAN, I can then run

perldoc Text::CSV

to get the docs from it.

Conversely, I just installed the net-ssh gem.

[msoulier@tigger ~]$ gem list --local | grep ssh
net-ssh (1.0.9)
[msoulier@tigger ~]$ ri net-ssh
Nothing known about net-ssh
[msoulier@tigger ~]$ ri net/ssh
Nothing known about net/ssh
[msoulier@tigger ~]$ ri Net::SSH
Nothing known about Net::SSH

So, what is ri for? Seems to work on built-in classes like Array, but
not gem code.

Thanks,
Mike

Hi Mike.

ri seems to be broken in old version (stable release), but it might
be corrected in the latest releaes.

Anyway, here's how to fix ri problem for gem:

Use gemri for now.

It's a new command in the latest RubyGems release, but it gives ri
capabilities to gems.

I have the latest release, and I don't see a gemri executable.

I just did:

gem update --system

Then I was able to do:

gemri

and get results. You must be using RubyGems 0.9.0.

Yup, that worked. Mind you...

[msoulier@tigger ~]$ gemri Net::SSH
Nothing known about Net::SSH
[msoulier@tigger ~]$ gemri net-ssh
Nothing known about net-ssh
[msoulier@tigger ~]$ gemri net/ssh
Nothing known about net/ssh

irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'net/ssh'
=> true

So, how do I pull up the docs?

If Net::SSH has rdoc disabled, you'll not get docs or ri. If you
installed Net::SSH before upgrading, you'll have to do something to
generate the ri data.

% gem rdoc net-ssh
% gemri Net::SSH

Ok, did that.

-------------------------------------------------------- Class:
Net::SSH
(no description...)
------------------------------------------------------------------------


Constants:
----------
EXTERNAL_SERVICES: Hash.new


Instance methods:
-----------------
register_service, start

Wow, not much there. There's a lot more in the html docs provided for
the gem_server. I guess for some reason these are not one and the same?
That's odd.
