How can I find out the current Git branch name from code, without using git itself? .git/HEAD file?
Question
I am writing some jazzy code which needs to determine the current branch name programatically. I don't want to take a dependency on any git executables, I just want to look in the .git directory.
Can I just inspect the .git/HEAD file?

假设您的git仓库始终在分支上，并且从未签出特定的SHA，是的。

Yes you can use .git/HEAD file. Mine says that rel-8.0 is the current branch:
$ cat .git/HEAD
ref: refs/heads/rel-8.0
If I checkout a tag it just gives me the hash:
$ git checkout 7.5
$ cat .git/HEAD
