Question about matching completions with descriptions

Question about matching completions with descriptions

I have a question about the _describe builtin.
I am building a binary that provides dynamic completions using a completion
function.

Is to possible to provide completions to _describe that will be matched not
only on the text of the completion but also on words/text in the
description? Or, is it possible to turn off completion matching entirely
and have zsh present the user with a verbatim set of completions provided
to compadd or _describe? Thanks in advance!

I asked this once and the answer was that that wasn't possible.  I'd
have linked you to the thread but I looked for it and can't find it :(

Does passing -U (and possibly -V) to compadd do what you need?

It looks like I need to match on the description prior to calling
_describe. Using -U and -V together achieved what I was trying to do. The
kicker was also adding compstate[insert]="automenu" to prevent common
prefix insertion which when you are matching within descriptions the common
prefix could be empty!
Thanks!
