inotify-commit, was Re: git guidance

Hi,

That said, out of pure curiousness I came up with the attached script 
which just uses inotifywait to watch a directory and issue git commands 
on certain events. It is extremely stupid, but seems to work. And at 
least it hasn't got the drawbacks of a real gitfs regarding the need to 
have a "separate" non-versioned storage area for the working directory, 
because it simply uses the existing working directory wherever that 
might be stored. It doesn't use GIT_DIR/WORK_DIR yet, but hey, should be 
easy to add...

Feel free to mess with that thing, hey, maybe you even like it and
extend it to match your proposed workflow even more. I for sure won't
use or even extend it, so you're likely on your own there.

Side-note: Writing that script probably took less time than writing this
email and probably less time than was wasted on this topic. Makes me
want to use today's preferred "Code talks, b...s... walks" statement,
but I'll refrain from that... Just because I lack the credibility to say
that, and the script attached is quite crappy ;-)

I could not agree more with the statement.

As it happens, I have a very delicate setup that we tested in a test 
environment as much as possible, but now we have to deploy it and I want 
to be able to rewind very quickly to a known-good state.

So I adjusted your script a little.  It now reads like this:

-- snip --
#!/bin/sh

# Originally by Bjoern Steinbrink, simplified by Johannes Schindelin

inotifywait -m -r --exclude ^\./\.git/.* \
        -e close_write -e move -e create -e delete . 2>/dev/null |
while read FILE_PATH EVENT FILE_NAME
do
        FILE_NAME="$FILE_PATH$FILE_NAME"
        FILE_NAME=${FILE_NAME#./}

        # git doesn't care about directories
        test -d "$FILE_NAME" && continue

        case "$EVENT" in
        *MOVED_TO*|*CREATE*)
                git add "$FILE_NAME"
                git commit -m "$FILE_NAME created"
                ;;
        *CLOSE_WRITE*|*MODIFY*)
                git add "$FILE_NAME"
                git commit -m "$FILE_NAME changed"
                ;;
        *DELETE*|*MOVED_FROM*)
                git rm --cached "$FILE_NAME"
                git commit -m "$FILE_NAME removed"
                ;;
        esac
done
-- snap --

Thanks for your original script!

Ciao,
