Ramifications of a git-sh-setup outside the PATH

Ramifications of a git-sh-setup outside the PATH

[Jonathan Nieder]

Hi gitsters,

I noticed in the release notes to Git 1.6.0 that dashed-form commands
are moving to a libexecdir outside the PATH. I have been using Git
with nd/dashless applied for about a month, and it does work well
(thanks!). There was one little glitch: to use hg-fast-export.sh from
fast-export.git (of repo.or.cz), I had to put git-sh-setup in the PATH.

I wanted to just change the ". git-sh-setup" line to ". git sh-setup",
but of course that will not work. Am I missing something?

hg-fast-export uses git-sh-setup to handle --help, to provide the
cd_to_toplevel function, and to set GIT_DIR. It would not take much
work to avoid using git-sh-setup, although for my needs it was easier
to put git-sh-setup in the PATH. But really, the use of git-sh-setup
does not seem strange to me at all. Is use of git-sh-setup in scripts
outside Git core discouraged?

The location of git-sh-setup was discussed before in the thread
<http://thread.gmane.org/gmane.comp.version-control.git/33708>.
Thanks for your time, and thank you for Git!

Sincerely,
Jonathan

Try

    . "$(git --exec-path)/git-sh-setup"

"git-sh-setup" is not a command, but a Bourne Shell script you can use
in your scripts by including it. So ". git sh-setup" just tries to
_include_ file "git" (and will try $PATH and current directory) with
positional argument "sh-setup" (see man 1 bash, for example).
