How can I get the tip revision informations of a remote mercurial repository from a python script?
I want something like:hg tip.
AFAIK hg commands needs a local repository.
I found another approach with mercurial API : List remote branches in Mercurial. But I can't find a documentation on mercurial API to go further this way.
Any help would be very much appreciated.
Here's the "official" way to do it (based on the selected answer to which you linked):
$ ssh ry4an.org hg -R /srv/hg/unblog id -r tip
30117899846f tip
If you don't have ssh access to the remote repo then you probably have hgweb access, which makes information about the most tip commit availble at a URL like this: http://ry4an.org/hg/unblog/raw-rev/tip
You can definitely use the Mercurial internals as seen in @resi's excellent answer, but be sure you're aware it's actively discouraged.
