This walkthrough will get your existing mercurial repository:
- speaking to bitbucket with mercurial
- speaking to github with git via hg-git
This article’s instructions worked as of 2012/12.
I’m assuming that you’re starting with a local mercurial repository you already use and enjoy — if you’ve never used mercurial, see the wonderful tutorial at hginit/kiln for a great introduction.
Install / Verify hg-git
hg-git lets your mercurial installation speak natively to a git repository. It’s pretty slick but it doesn’t seem to like virtualenv very much. You can get weird-but-surmountable errors.
$ pip install hg-git
Verify that hggit works:
>>> import hggit >>>
Then add it to your base mercurial config (
Quick aside: problems with hg-git and virtualenv?
I had problems with these. My mercurial application was system-installed, not tied to my python installation. My virtualenv was compeltely confused. (Now I know why everyone says “no site packages”.) Check that your mercurial is tied to your virtualenv:
$ which python <path_to_python> $ which hg <path_to_mercurial>
The roots should be the same; mine were not aligned. To get around this specific problem, you can try either of the following:
1. clear system mercurial
Easier solution if you have administrator permission: uninstall system mercurial, reinstall fresh in your virtualenv via
pip install mercurial hg-git
2. override system mercurial
$ pip uninstall mercurial $ pip upgrade --force mercurial
This will cause your virtualenv to override the stock installation.
Mercurial-to-bitbucket is really well defined and easy to set up. Start with Bitbucket’s guide. There is nothing special to do here, and you should end up with the ability to:
$ hg push https://email@example.com/your_user/your_project
Create repository on github with desired name, preferably mirrored. I had to
git init (elsewhere) and commit a trivial file (I chose an empty
For convenience, add the remote targets to your
[paths] bitbucket = ssh://firstname.lastname@example.org/your_user/your_project github = git+ssh://email@example.com/your_user/your_project.git
# your mercurial repository $ cd your_project # make a bookmark of master for default, so a ref gets created that git can hang on to $ hg bookmark -r default master # speak mercurial to bitbucket $ hg push bitbucket # speak git to github $ hg push github
