Dumb "continuous" commit dumb question

Hello,

Is it possible to enable git to automatically and continuously "softly" commit or stage *all* changes to a [subset of] files in a repository, without my intervention, as they happen? Perhaps via a daemon which monitors the disk for explicit file-saving?

Of course, I would still be able to perform explicit commits (with descriptive comments) and other git commands, in which case there probably should be smart handling of the recent soft history. For example, it could simply be discarded.

I understand that I could simply remember to commit and/or branch early and often. But given that changes by an individual on a given branch are well-ordered by time, and that the "continuous" operation may be cheap in many situations, a "live" journal could be useful.

Perhaps a better term is branch-aware undo or git with microstructure.

Sorry if this is old stuff or plain crap.

Thanks.

Sincerely, Pat LeSmith
