Mercurial - How to specify branch on commit?

Question

I would like, when a user commit a changeset, to show a message mentioning the branch where the changeset was committed.

Example:

$hg commit -m 'Fix bug'
Changeset committed on branch bugfix

Do I actually need to modify the hg commit code or is it a quicker/simpler way of doing it?

Answer 1

ssg's answer is unfortunately not portable to e.g. Windows (because of the backticks), but this should work:

# UNIX-like
[hooks]
commit=hg log -r $HG_NODE --template "Committing on branch {branch}\n"

or

# Windows
[hooks]
commit=hg log -r %HG_NODE% --template "Committing on branch {branch}\n"

Answer 2

Add to your repository's .hg/hgrc:

[hooks]
commit=echo "Changeset committed on branch `hg branch`"
