I'd like to get a git log for the repository and all submodules. The manpage says that git log --submodule should be used but this doesn't work for me.

------- Edit -------

As an example - what I run:

git clone git://git.typo3.org/TYPO3v4/Core.git
cd Core
git submodule init && git submodule update
git log --submodule

The output of git log --submodule doesn't include the commits from any of the submodules anyhow - just the commits where submodule pointers have been changed.

What's missing?

  • What do you mean it doesn't work? Are there actually commits in the submodule to be displayed in the commit range you're running git-log over in the parent repo? – Cascabel Jan 13 '12 at 05:48
  • Did you initialize and update your submodules? (`git subomdules init`/`git submodules update`) – VonC Jan 13 '12 at 07:37

It sounds as though you're expecting --submodule to interleave submodule commits with those from the parent repository in the git log output, but unfortunately that's not what it does.

The --submodule argument defines how submodule differences are shown - so you'll only see its effects if you're using e.g. git log -p to show patches for each change. Normally, git log -p will just show the hashes for the before and after commits for a submodule change in the patch:

$ git log -1 -p

With --submodule you get the actual commit message from the submodule listed:

$ git log -1 -p --submodule
