A while back, I mention one of the feature of Git I was missing in Mercurial. It was the nice way git display a summary of the changes when you update. But that’s it, no more regrets!
I discovered the world of mercurial hooks, and particularly this one:
Create a file with
from mercurial import patch, util def diffstat(ui, repo, **kwargs): '''Use it like: [hooks] commit.diffstat = python:/path/to/this/file.py:diffstat changegroup.diffstat = python:/path/to/this/file.py:diffstat ''' if kwargs.get('parent2'): return node = kwargs['node'] first = repo[node].parents().node() if 'url' in kwargs: last = repo['tip'].node() else: last = node diff = patch.diff(repo, first, last) ui.write(patch.diffstat(util.iterlines(diff)))
And as explain in the hook, add this to your ~/.hgrc
[hooks] commit.diffstat = python:/path/to/this/file.py:diffstat changegroup.diffstat = python:/path/to/this/file.py:diffstat
That’s it, next time you update or commit, you’ll see a nice summary of the modifications. Handy to know what’s happening at a glance.
