Hi,
I was writing a new completion for ri, the ruby documentation viewing
tool, when I came upon a small problem: ri takes as argument the full
name of a class, module or method.
It can generate a list of all documented functions, which I use to fill
the completion list. This list is very long, so I tried to use
_multi_parts to get a better overview. The problem is: ri uses
different separators to differentiate between class method and instance
methods. For example I have these alternatives:
File (class or module)
File::basename (class method)
File.path (instance method)
File::Stat (another class)
File::Stat::new (another class method)
I currently only use _multi_parts with "." as separator - I don't know
enough zsh scripting to build something to use multiple separators. Any
ideas?
Greetings Tobi

BTW, I've got another _ri completion that was recently written by Sir Raorn.
https://bugzilla.altlinux.org/show_bug.cgi?id=7593
Please take a look (I believe it is available under the same terms as zsh).
