First off, may I say that ri, with its recent improvements, is now
useful to me for the first time since I started using ruby? With the
spaces after the commas, the listing of a class’s superclass, the
ability to search up the class hierarchy, and so forth, I can now
usually find what I’m looking for and read the result.
That said, there remain a few edge cases on my machine where ri seems to
break down. An example is String#squeeze, which comes up with an empty
description:
--------------------------------------------------------- String#squeeze
squeeze(del=nil)
From /usr/local/share/ri/1.8/site/String/cdesc-String.yaml
[no description]
There is, however, another String#squeeze that does have a
description. Where there’s a choice like this, I’d like to see the one
with the description. I can say:
$ ri --no-site String#squeeze
and that does work, but it also causes a huge delay both now while the
cache is rebuilt and on the next ri search without --no-site while the
cache is rebuilt again. What I’d really like is syntax for choosing
between different String#squeeze. For example, maybe the -i interactive
option could give me the ability to enter numbers?

hm…I have no problems with String#squeeze
not for ruby 1.8.7 nor for 1.9.1
but I prefer fastri over ri, because…it’s faster =D

Note also that you can lookup things in irb
irb(main):002:0> help “String#chars”
----------------------------------------------------------- String#chars
str.chars => anEnumerator
str.chars {|substr| block } => str
Returns an enumerator that gives each character in the string. If a
block is given, it iterates over each character in the string.
"foo".chars.to_a #=> ["f","o","o"]
=> nil

Faster, but long ago broken OMM. It stopped working one day (after a
rdoc update, I think) and just never worked again. It doesn’t look very
supported and I assume it is no longer maintained…?
I am still back at 1.8.6.

More than one method matched your request. You can refine
your search by asking for information on one of:
String#squeeze!, String#squeeze, String#squeeze!, String#squeeze
Now what? m.
looks like a bug. repost to ruby core?

You seem to have two sets of ri data installed. Try locate cdesc-
String.yaml to see where the two sets live, then delete the one
without documentation.

But what I asked about was String.squeeze. Same problem:

Good call! That worked. Thanks! m.

maybe our next tweak on gem check should do this check too?

RDoc 2 has a fast ri, from cache:
$ time ri String#squeeze > /dev/null
real 0m0.398s
user 0m0.339s
sys 0m0.054s

This one seemed to be an artifact of ruby’s make install-doc, I’m
unsure how to reproduce it.
RDoc now only looks in the latest gem dirs for documentation, so this
shouldn’t happen for ri for gems even with multiple versions.
