How regenerate ri data?

http://rubyforge.org/forum/forum.php?forum_id=25981:

  • ri now walks the ancestors of a class looking for a method e.g. ri
    File#read displays documentation for IO#read (may require regeneration of
    ri data)

Sounds cool! But:

Big-iMac-Attack:~ mattneub$ rdoc --version
rdoc 2.1.0
Big-iMac-Attack:~ mattneub$ ri --version
ri 2.1.0
Big-iMac-Attack:~ mattneub$ ri File#read
Nothing known about File#read

So it sounds like I do need to regenerate the ri data. How? Thx - m.

% sudo make install-doc

in the source tarball (assumes you installed your own ruby–if you
didn’t, you deleted your rdoc data?)

Didn’t help, presumably because the rdoc being used is the one in the
tarball, not the new version…?

rdoc --all --ri

This rebuilt my documentation just fine. But

ri File#read

still gets a “nothing known” response.

So, I’m using rdoc 2.1.0, I’ve regenerated the docmentation, but I’m
still not seeing this new feature working. Do other people see it
working? If so, what might be the problem here?

works for me:

% ri File::read
--------------------------------------------------------------- IO::read
IO.read(name, [length [, offset]] ) => string

  Opens the file, optionally seeks to the given offset, then returns
  _length_ bytes (defaulting to the rest of the file). +read+

ensures
the file is closed before returning.

     IO.read("testfile")           #=> "This is line one\nThis is

line two\nT
his is line three\nAnd so on…\n"
IO.read(“testfile”, 20) #=> “This is line one\nThi”
IO.read(“testfile”, 20, 10) #=> "ne one\nThis is line "

RDoc 2.1.0 won’t generate RDoc from 1.8 due to a bug introduced before
2.0 to handle C prototypes. I’ll release a 2.1.1 tonight or tomorrow
and include proper instructions on how to do this.

Actually what I did was to blow away /usr/local/share/ri/1.8/system and
then

sudo rdoc --all --ri-system

This rebuilt my documentation just fine. But

ri File#read

still gets a “nothing known” response.
