git-stash

[Johannes Schindelin <Johannes.Schindelin@gmx.de>]

Hi,

I just was in the need for git-stash (for the 1e6th time this year), but 
instead of writing a script, I though I'd try the "!" convention for 
aliases. Works quite well for me:

git config alias.stash '!git diff-files --name-only -z | git update-index 
-z --stdin && tree=$(git-write-tree) && commit=$(echo stash $(date) | 
git-commit-tree $tree) && git-update-ref refs/heads/stash $commit && 
git-reset --hard'

(This is one long line.)

With this, I can now say "git stash" with a dirty working directory, and 
it will have the same effect as "git reset --hard", i.e. reset to the 
clean state in HEAD.

Except that all my changes are stashed away in the branch "stash". It is 
not really a branch, as I expect it to jump from loose end to loose end, 
like this:

A - B - C - D - E - F - G - H - ...  (master branch)
  \               \       \
    A'  ..          E'  ..  G'       (stash branch)

The ".." denote reflog connections: "git log stash" will show G' and as 
its parent G with its history, while "git reflog stash" will show G', and 
then E', and then A'.

Maybe it is not only useful for me...

Ciao,
