Git alias:
snapshot = !git stash push --include-untracked --message \"snapshot: $(date)\" && git stash apply \"stash@{0}\"
Example:
git snapshot
Take a snapshot of your current working tree without removing changes.
This is handy for refactoring where you can’t quite fit what you’ve done into a commit but daren’t stray too far from now without a backup.
Running this …
git snapshot
… creates this stash:
stash@{0}: On feature/handy-git-tricks: snapshot: Mon Apr 8 12:39:06 BST 2013
… and seemingly no changes to your working tree.
