Mercurial: block commits if subrepos are dirty?

Question

Is there any simple way to prevent commits to a repository if it has dirty subrepos?

It's really annoying when a subrepo is accidentally committed along with a parent repository.

Answer 1

I don't know where your line for simple lands but you could do a hook like this:

for subrepo in $(find $(hg root) -type d -name .hg) ; do
  if [ "$(hg --repository ${subrepo$$.hg} status -mard)" != "" ] ; then
    echo Uncommitted subrepo changes in ${subrepo%%.hg}
    exit 1
  fi
done

Save that in something like ~/bin/dirtysubrepos and then add this to your ~/.hgrc:

[hooks]
precommit.dirtysuprepos = ~/bin/dirtysubrepos

I can't comment on Ry4an's answer for some reason (no "Add comment" link for me to click on), but there's a minor typo in his answer: there's an ${subrepo$$.hg} that should be ${subrepo%%.hg}.
