How do I convert a git repository to mercurial?

Question

I\'ve been developing a java application using git as source code repository. I\'d like to share the project with other java developers and hg seems to be most used by them.

Answer 1

The convert extension may work for you, but if it doesn't, you might want to check out tailor which is a general purpose tool for converting among the various distributed SCMs.

Answer 2

New player in town: git-remote-hg. It provides native bridging support in git.

Just:

hg init ../hgrepo
git push hg::$PWD/../hgrepo

Answer 3

Distributed revision control with Mercurial states:

The revision control tools supported by convert are as follows:

• Subversion
• CVS
• Git
• Darcs

So maybe you don’t need any additional tool?

Answer 4

You may want to look at the http://hg-git.github.com/ utility: a Git plugin for Mercurial

This plugin is originally developped by the guys of GitHub, and allows the convert from git<->mercurial losslessly. In theory, you could even be able to clone the hg repository.

Answer 5

By using the Mercurial Convert extension

Add the following lines to your .hgrc or to enable the extension :

[extensions]
hgext.convert=

And typing a

cd src
hg convert --datesort . dst

(even though it can lead to some issues...)

Note:: metrix reports that this might not work:

     hg convert --datesort src dst

Note: there happens to be a bug with hg convert if you perform this command from a directory other than the source directory.
You will get the following error:

abort: cannot read tags from git-repo4/.git

Confirmed with git 1.7.9 and Mercurial 2.6.2 on Windows XP

Answer 6

In the Git folder with all my Git repositories I created the Git2Hg.cmd file with the following content:

set PATH=%PATH%;C:\Program Files\TortoiseHg
set PATH=%PATH%;C:\Program Files\Git\bin
hg convert %1

Now I can convert a Git repository to Hg by typing this in a CMD:

Git2Hg "Folder Name"
