Re: cygwin chere not working with zsh version 4.3.10 but worked for 4.3.9

Dear Ben:
It turns out that commenting out CHERE_INVOKING fixed problem. Evidently, there was no CHERE_INVOKING environment variable. 

Mysterious.

Thanks again!

Hi,


Greetings, Reckoner,


This command line from cygwin chere is not working anymore for zsh
version 4.3.10, but it worked for zsh version 4.3.9:

   C:\cygwin\bin\run.exe C:\cygwin\bin\rxvt.exe -e /bin/xhere /bin/zsh.exe "%L"

This is supposed to open a new zsh at the directory provided by the
%L variable. With version 4.3.10, it opens a shell, but leaves you
in $HOME instead of %L


Hmm.  I don't recall there being anything specific with reguards to
cd'ing to $HOME on startup in 4.3.10.  The sample startup profile,
/etc/zprofile, (source is at
/usr/share/doc/zsh-4.3.10/StartupFiles/etc/zprofile) was updated to be
in sync with /etc/profile from the base-files package, though those
changes weren't all that effective (spaces, tabs, comments, etc).  In
/etc/zprofile we look for an env var named CHERE_INVOKING and either
unset it or do "cd $HOME":

# Make sure we start in home unless invoked by CHERE
if [ ! -z "${CHERE_INVOKING}" ]; then
         unset CHERE_INVOKING
else
         cd "${HOME}"
fi

So, clearly, this should be working in tandum with chere.  You might
want to try commenting out the above block and see if it does what you
want.  If so, it may be that chere has changed how "CHERE_INVOKING" is
being set into the environment or, maybe the name changed, or perhaps
something related to that.

I'll install chere and see what I can find out.


any help appreciated.




I installed chere, and it appears to work fine for me.  I tried first
with mintty, and then had to install rxvt before testing with it (only
had rxvt-unicode installed).

I notice that the rxvt command prepends Cygwin's 'run.exe' wrapper,
whereas the mintty version lacks it:

rxvt: (as you listed):
C:\cygwin\bin\run.exe C:\cygwin\bin\rxvt.exe -e /bin/xhere /bin/zsh.exe "%L"

mintty:
C:\cygwin\bin\mintty.exe -e /bin/xhere /bin/zsh.exe "%L"

Maybe try dropping that?:
C:\cygwin\bin\rxvt.exe -e /bin/xhere /bin/zsh.exe "%L"

(It still works either way for me, but that's just one more variable to
eliminate.)
