RE: Case-insensitive completion problems with Cygwin 1.7

[John Cooper <John.Cooper@xxxxxxxxxxxxx>]

Unfortunately, the updated fake-files below does not actually fix the problem. It appeared to work on my home computer because HOME is set to "/c" and I was testing the completion from /c. If I change to any other directory, typing `ls c:/<Tab>' does not work as expected, but just (after a short delay) starts to complete files in the current directory.

So, it still seems that completing through a drive letter has regressed in zsh 4.3.10 (compared with 4.3.2). Does anyone have any ideas on other settings I could try to get this to work?

Thanks,

    --- John.

Through trial-and-error I found that changing fake-files to be:
  zstyle ':completion:*' fake-files '/c:c:' '/d:d:' '/b:b:' '/o:o:' '/w:w:' '/r:r:' '/v:v:'
.. instead of:
  zstyle ':completion:*' fake-files '/:c:' '/:d:' '/:b:' '/:o:' '/:w:' '/:r:' '/:v:'

.. allows case-insensitive completion to work correctly, even when using a drive letter.

However, I've noticed 2 side-effects:

1. When I type `ls /c/<Tab>' the listing includes a spurious 'c:' entry. This does not happen when I use `ls c:/<Tab>'.
2. When I use `ls /c/<Tab>' files with the `execute' bit set are shown according to the `ex' color I've defined in LS_COLORS, and this matches the coloring I see when I just type `ls'. However, when I use `ls c:/<Tab>' executable files are not colorized as expected (just shown as white). It's as if the executable-ness of files is somehow lost when completing via c:/.

Btw, for the coloring I have the following in my .zshrc:
  zstyle ':completion:*:default' list-colors ${(s.:.)LS_COLORS}

I've just upgraded to Cygwin 1.7 (and zsh 4.3.10) and found that
case-insensitive completion no longer works when the path starts with a
drive letter.

If I start off with `zsh -f' file completion works as expected even when
using a drive letter:
$ ls /c/<TAB>    # works as expected
$ ls c:/<TAB>    # works as expected

However, after running the following (to allow for case-insensitive
completion):
  zstyle ':completion:*' matcher-list 'm:{a-z}={A-Z}'
  autoload -U compinit
  compinit -C
$ ls /c/<TAB>   # still works as expected
$ ls c:/<TAB>   # fails - no completions are listed

Previously I was using zsh 4.3.2 running under Cygwin 1.5, and I used to
additionally have the following lines in my .zshrc:
zstyle ':completion:*:paths' accept-exact 'c:' 'd:' 'b:' 'o:' 'w:' 'r:' 'v:'
zstyle ':completion:*' fake-files '/:c' '/:d' '/:b' '/:o' '/:w' '/:r' '/:v'

This allowed completion to work when using drive letters in zsh 4.3.2, but
it doesn't work with zsh 4.3.10 and Cygwin 1.7.

Is there any other way around this, so that I can still perform
case-insensitive completion using c:/ ?

Btw, my /etc/fstab contains the following, which allows me to use /c/ rather
than the default /cygdrive/c/
none / cygdrive binary,posix=0,user 0 0

Thanks,
