git-remote-hg is the semi-official Mercurial bridge from the Git project, once
installed, it allows you to clone, fetch and push to and from Mercurial
repositories as if they were Git ones:
git clone "hg::http://selenic.com/repo/hello"
To enable this, simply add the
git-remote-hg script anywhere in your
curl https://raw.githubusercontent.com/felipec/git-remote-hg/master/git-remote-hg -o ~/bin/git-remote-hg chmod +x ~/bin/git-remote-hg
That’s it :)
Obviously you will need Mercurial installed.
If you want to see Mercurial revisions as Git commit notes:
% git config core.notesRef refs/notes/hg
If you are not interested in Mercurial permanent and global branches (aka. commit labels):
% git config --global remote-hg.track-branches false
With this configuration, the 'branches/foo' refs won’t appear.
If you want the equivalent of
hg clone --insecure:
% git config --global remote-hg.insecure true
If you want
git-remote-hg to be compatible with
hg-git, and generate exactly
the same commits:
% git config --global remote-hg.hg-git-compat true
Remember to run
git gc --aggressive after cloning a repository, especially if
it’s a big one. Otherwise lots of space will be wasted.
The newest supported version of Mercurial is 6.2, the oldest one is 2.4.
To push a branch, you need to use the 'branches/' prefix:
% git checkout branches/next # do stuff % git push origin branches/next
All the pushed commits will receive the "next" Mercurial named branch.
Note: Make sure you don’t have
The simplest way is to specify the user and password in the URL:
git clone hg::https://user:firstname.lastname@example.org/user/repo
You can also use the schemes extension:
[auth] bb.prefix = https://bitbucket.org/user/ bb.username = user bb.password = password
Finally, you can also use the keyring extension.
The only major incompatibility is that Git octopus merges (a merge with more than two parents) are not supported.
Mercurial branches and bookmarks have some limitations of Git branches: you can’t have both 'dev/feature' and 'dev' (as Git uses files and directories to store them).
Multiple anonymous heads (which are useless anyway) are not supported: you would only see the latest head.
Closed branches are not supported: they are not shown and you can’t close or reopen. Additionally in certain rare situations a synchronization issue can occur (Bug #65).
Limitations of Git’s remote-helpers framework apply.
There are other
git-remote-hg projects out there, but this is the original,
which was distributed officially in the Git project.
Over the years many similar tools have died out, the only actively maintained alternative is mnauw’s fork of this project: mnauw/git-remote-hg. I’ve merged some of his patches, and he has merged some of my patches, so the projects are mostly in sync, but not quite. In particular Nauwelaerts' fork has many administrative extensions, which although useful to some people, I don’t believe they belong in the core.
