Rdoc reinstall breaks fast-ri - now what?

Ruby
1

I am really just not having any luck with rdoc / ri these days. Because
the new version of rdoc promised that File#read would finally succeed
(automatic lookup of methods in the supercclass), I downloaded it. It
didn’t change anything so I rebuilt my documentation from scratch. Now
fast-ri is broken. Can anyone divine from this error what’s gone wrong
and what I should do? Thx - m.

Looks like qri is using RDoc 1.0.1, which is shipped with ruby. RDoc
2’s on-disk YAML format is not backwards compatible with RDoc 1. RDoc
2 can read RDoc 1’s format due to some use of regular expressions.
fast-ri would need to be updated to read the RDoc 2 classes.

Thx, Eric, as always. If this is right, then it’s all up to fastri. I’ve
filed a bug report at fastri.rubyforge.com, and also I’ve notified the
TextMate list (TextMate’s RubyMate help functionality uses qri, which is
how I discovered the problem). m.
