Hello,
I found the discussion earlier this month "ZSH DOS/Windows" rather
informative. This got me looking at some problems I've had using zsh as
my default shell under Cygwin. This is zsh 4.0.6 installed from a
recent Cygwin setup.
$ uname -a
CYGWIN_NT-5.1 nbbillb 1.3.20(0.73/3/2) 2003-02-08 12:10 i686 unknown
unknown Cygwin
The problem I'm having is that zsh refuses to complete on mounted paths:
$ mount
C:\cygwin\bin on /usr/bin type system (binmode)
C:\cygwin\lib on /usr/lib type system (binmode)
C:\cygwin on / type system (binmode)
C: on /c type system (textmode)
If I try to complete on /c/<C-D>, zsh just barks at me. After some
experimentation, I found the work around is to *not* set HOME to
something that uses a mount. But I want my HOME in a different place
than the default that's based on HOMEDRIVE and HOMEPATH.
The following hack seems to work. First in My Computer, Environment
variables, I created a CYGWIN_HOME User variable set to
/cygdrive/c/home. Then, I modified /etc/zprofile adding the following
after the USER="`id -un`" line:
# Get a specfic home directory
if [ -n "$CYGWIN_HOME" ]; then
if [ -d "$CYGWIN_HOME" ]; then
HOME="$CYGWIN_HOME"
else
echo "CYGWIN_HOME points to a non existant directory!"
fi
fi
Then, I created a zygwin.bat script in my Cygwin root directory C:\cygwin:
@echo off
C:
chdir C:\cygwin\bin
zsh -l -i
So, I guess there's a bug in the completion and/or the way HOME is handled.

that is not strictly speaking Zsh fault. Zsh is using globbing when
completing file names and globbing does not return Cygwin mount points. Just
try
cd /
echo *
or simply
echo /*

The bug is in the way Cygwin treats own mount points. Zsh has workaround for
it:
fake-files
This style is used when completing files and looked up without a
tag. Its values are of the form `DIR:NAMES...'. This will add
the NAMES (strings separated by spaces) as possible matches when
completing in the directory DIR, even if no such files really
exist.
This can be useful on systems that support special filesystems
whose top-level pathnames can not be listed or generated with glob
patterns. It can also be used for directories for which one does
not have read permission.
So set it to
zstyle ':completeion:*:fake-files' /:'c d cygroot' /cygroot:'c d ...' ...
etc
(IIRC virtual root is called /cygroot).
If you come up with a script that parses mount table and automatically
creates this style we can add it to distribution so whoever packages Zsh for
Cygwin could use it in /etc/zshrc by default. I once intended to do it but I
do not use Cygwin now.
