completion display question

completion display question

[Greg Klanderman]

I was wondering if there's some way for completion listings to
indicate the common portion - if there are many similar looking
completions, you want some indication of what characters you can
type next to disambiguate.  I'm imagining maybe some way to
highlight the unmatched portions of the completions - is that
possible?

I really like the removable suffix highlighting, btw!

thanks,
Greg

It'd be nice if this worked:

zstyle -e ':completion:*:*:*:*' list-colors \
  'reply=("=(#b)(${(q)compstate[unambiguous]})*=0=01;31")'

Unfortunately the list-colors style is evaluated "too early," before
the completion internals have assigned compstate[unambiguous].

So I suggest you start from the following and try tweaking the
(${(q)PREFIX}) part until you get something close enough to what
you want:

zstyle -e ':completion:*:*:*:*' list-colors \
  'reply=("=(#b)(${(q)PREFIX})*=0=01;31")'

E.g. you may want (#b)*(${(q}PREFIX:t})* or something like that, and you
may want different patterns for different contexts.

Replace "01;31" with another color spec if you don't like red.  Also (q)
may not be sufficient to quote the prefix for pattern purposes.

Finally getting back to this, thanks Bart, very cool!

Is there some way to have it depend on which element of my
matcher-list is in effect?  Gotta go read the manual...

thanks,

Unfortunately, no, that's another item that's not determined until
much later than the point at which the list-colors style is looked up.
