At one point I created an autocommit script that commits every second which you can change the commit message by setting it in a file called "current-task"

Could combine this with automatic synchronization with pulling too.

  #!/bin/bash

  while true; do

     sleep 1

     (cd app ; git status -z;
     git add . && git commit -m "autocommit $(cat ../current-task)" ; git push -f app);

  done > autocommit.log 2>&1

Will add a reference to this comment, if I end up using it. :)

Git commits without any changes added are noops, that's the behaviour I rely on.

( nothing automatic, no concurrency management of course )
