I use Git for many things, and I have written several utilities that wrap git
commands (e.g. pushing changes to the theme for my wife’s website from the dev
site to the production
site). A common
requirement is that the local copy is clean: no uncommitted changes, and no
unpushed commits. I had been checking for uncommitted changes by testing if
there is any output from git status, but in most cases I wasn’t checking for
unpushed commits. I decided to remove the duplication and improve the
implementation by writing a git subcommand:
git-check-local-copy-is-clean,
invoked as git check-local-copy-is-clean. You can optionally ignore unpushed
commits by using --ignore-unpushed-commits if you just care about uncommitted
changes.
