Convert Mercurial project to Git

Ok I finally worked this out. This is using TortoiseHg on Windows. If you're not using that you can do it on the command line.

1. Install TortoiseHg
2. Right click an empty space in explorer, and go to the TortoiseHg settings:

3. Enable hggit:

4. Open a command line, enter an empty directory.

5. git init --bare .git (If you don't use a bare repo you'll get an error like abort: git remote error: refs/heads/master failed to update

6. cd to your Mercurial repository.

7. hg bookmarks hg

8. hg push c:/path/to/your/git/repo

9. In the Git directory: git config --bool core.bare false (Don't ask me why. Something about "work trees". Git is seriously unfriendly. I swear writing the actual code is easier than using Git.)

Hopefully it will work and then you can push from that new git repo to a non-bare one.

If you want to import your existing mercurial repository into a 'GitHub' repository, you can now simply use GitHub Importer available here [Login required]. No more messing around with fast-export etc. (although its a very good tool)

You will get all your commits, branches and tags intact. One more cool thing is that you can change the author's email-id as well. Check out below screenshots:

You can try using fast-export:

cd ~
git clone https://github.com/frej/fast-export.git
git init git_repo
cd git_repo
~/fast-export/hg-fast-export.sh -r /path/to/old/mercurial_repo
git checkout HEAD

Also have a look at this SO question.

If you're using Mercurial version below 4.6, adrihanu got your back:

As he stated in his comment: "In case you use Mercurial < 4.6 and you got "revsymbol not found" error. You need to update your Mercurial or downgrade fast-export by running git checkout tags/v180317 inside ~/fast-export directory.".
