# Keeping track of repository versions with Git¶

The command:

python $CLAW/clawutil/src/python/clawutil/claw_git_status.py  will report on the status of all Clawpack repositories found, e.g. what branch is checked out, the hash of the most recent commit, and any tracked files with uncommitted changes. This information will be saved to a file claw_git_status.txt and any diffs found for uncommitted changes will be saved to a file claw_git_diffs.txt. An optional command line argument allows you to save these files in a different directory, e.g. python$CLAW/clawutil/src/python/clawutil/claw_git_status.py _output


This is often useful to do when running a code if you want to later determine exactly what version of the code was used, particularly when doing regression testing.

The function \$CLAW/clawutil/src/python/clawutil/runclaw.py now has an argument print_git_status (with default value False). Calling runclaw with print_git_status == True will write these files to the output directory specified by the outdir argument.

Setting the environment variable GIT_STATUS to True will insure that make .output creates output directories containing the claw_git_status files.
