Completions under NT / cygwin

Completions under NT / cygwin

[Vin Shelton]

At work I have built zsh from the latest CVS sources using the cygwin
toolkit.  When I use the new completion system, I can not complete
fully-qualified filenames, be they of the form "/cygdrive/d/views/..."
or (more conveniently) "d:/views/...".  Is there a magic style setting
I need to use to complete these filenames?

TIA,
  vin shelton

For /cydrive use something like

zstyle ':completion:*' fake-files '/:cygdrive'  '/cygdrive:c d'

See description of fake-files. You can add some magic to startup scripts to
find out what drives are actually available (and even get real cygdrive prefix
from registry).

For d:/ unfortunately now solution as for now. The rpoblem is, zsh does not
knwo that it is an absolute filename. The simplest solution wuld be to stick
cygpath in approptiate place in _path_files:

mw1g017@MW1G17C% cygpath -u d:/foo
/cygdrive/d/foo

This would imply that completion will replace d:/foo by it's unix name.

An alternative to Andrej's suggestion which I have used is to use
something like:

for drive in a b c d k p r; hash -d $drive=/cygdrive/$drive

in .zshrc. Then you can refer to other drives with, for example ~c/
Completion after that works fine (unless it requires something else in
my setup).

For some reason if you omit the hash -d and just set the variable, i.e.
for d in a b c; $d=/cygdrive/$d
I get error messages like this:
/home/administrator/.zshrc:48: no such file or directory: r=/cygdrive/r
Note that this is a fairly old version of zsh so this might be fixed by
now - I only rarely use cygwin.

I doubt that. /cygdrive/r is pure virtual "directory" which means, any normal
file operation on it fails. Zsh probably tries to stat it.

fake-files was invented exactly to allow /cygdrive/x completion under cygwin.
It works nicely. Note, that it will work in *any* context where filename is
expected.
