I'm developing a git plug-in, and I need to know when a local repo is changed (can commit changes), ahead (can push to remote) or behind (can pull from remote) using the command line.
This is what I am doing so far:
Can commit?
If
git diff-index --name-only --ignore-submodules HEAD --
returns something, then yes, there are changes to commit.Can push?
If
git status -sb
contains the word ahead in it's output, then yes, there are commits to push.Can pull?
Nothing implemented yet.
The can commit? part seems to work properly. Can push? only works for the master branch, and this is a huge problem.
How can I safely check if, on every branch, a git repo has changes to commit, commits to push, or needs a git pull
?
