provide an environment variable with the temp directory name

[jeff350]

Describe the solution you'd like
add a XARGS_REPO_DIRECTORY variable to access the path of the temporary directory

Describe alternatives you've considered
I can't find an easy way to access the path

Additional context
I came across this issue while trying to use git-xargs to appy copier templates across a large number of repos. The issue is that copier requires both the template and target directory to be specified. Here copier's target directory needs to be git-args temp directory

Technically, this is already supported.

As you can see here it's just calling ioutil.TempDir which properly handles temp dir environment variables. (In my experience, most syscalls to get temporary directories respect some kind of env)

I was able to export TMPDIR on macOS and clone all repos to that directory, provided I created it first. This variable my differ based on OS.

@osterman Thank you for looking at the issue but this is not what I am trying to solve.

I am looking to expose the full path of the directory in /tmp that contains the repo currently being targeted as an environment variable that can be used inside the script that is ran by git-xargs.

I have opened #147 to implemented this feature and I am using it to meet my needs. it is just waiting on a review to get merged in.

Aha, my fault - I didn't catch that.
