Doing a bit of a search in the archives, the nearest I can find is
11635. That deals with _path_files and glob qualifiers on the
command-line when doing pattern based matching. Is that perhaps what
you were thinking of?

It was a comment by me in 16447 that led to (#q). I was suggesting
using things like -g '*.png(.)' back then so must have been thinking
clearer than earlier this week. I managed to forget why I had wanted to
add qualifiers in series but it might have been for the file-patterns

The documentation is fairly clear that a glob qualifier is a trailing
set of parentheses containing no `|', `(' (or `~' if it is special).
Not sure I understand what the "if it is special" means - anyone? The
_path_files stuff from 11635 believes the documentation, using the 
pattern \([^\|\~]##\)
So the patch below (to _files) uses that pattern to find a glob
qualifier in the argument to the -g option and sticks a #q in.

Unfortunately, the documentation doesn't give the whole story:
  *(e:'[[ -d ~/$REPLY || -d ../$REPLY ]]':) and
  *(e:'(( 1 ))':)
both work. Seems to me that anything is valid just so long as it is
quoted. *(e'|'true'|') works while *(e|true|) doesn't.

So how do I match a quoted string with a glob? Does anyone have something
already? Is it even possible given nested quoting?

The only thing I can think of would be to dig into the C and add a
globbing flag which matches quoted characters, unquoting them before
matching so I could do something like:

I'm inclined to apply this patch as it is for now. I can't see any
existing uses of qualifiers with quotes and we could always add `#q'
manually for the odd case and exclude quotes along with |, ( and ~ in

My tip for the day for taking advantage of this change is this style:

zstyle ':completion:*:approximate*:*' file-patterns \
    '%p(D):globbed-files *(D-/):directories' '*(D):all-files'

With that, _approximate can correct `,zshrc' to `.zshrc'.

Now for the dull job of adding lots of (-.) qualifiers.


PS. Hope you get well soon Bart.
