git-mine

Python script that amends Git's current HEAD to minimise the commit ID.

Usage:

The only argument is the limit (in hex) below which the tool will exit.

./git-mine.py 000001

This will exit when the commit ID for HEAD starts 000000...

If the limit is omitted, then it defaults to 0001 (first 16 bits zeros).

The limit is a lexical comparison on the hex representation - to continue infinitely, specify - as the limit.

Use as post-commit hook

If you'd like this script to run after every commit, copy git-mine.py into the file .git/hooks/post-commit. It must be marked as executable.

If you want to specify a limit other than the default, you can write a script for .git/hooks/post-commit (must be executable) that provides it:

#!/bin/bash
/location/to/git-mine.py 0001

Alternatively, you could just change DEFAULT_LIMIT in the source.
