Dependencies

Mercurial (hg) and python must be installed and in your $PATH.

If this is a fresh checkout run

$ git submodule update --init

to pull in fast-export. If for some reason you cannot do this get a copy of fast-export from http://repo.or.cz/w/fast-export.git and place it in the root of the checkout.

Installation

Either add /path/to/this/checkout/bin to your $PATH, or symbolic link /path/to/this/checkout/bin/git-hg into a directory on your $PATH.

Alternatively you can execute

    $ make
    $ sudo make install

to install the script and all required fast-export files in /usr/local (you can change the destination by passing eg PREFIX=/usr to make install)

Usage

• Clone an hg repo, including ones over HTTP:

    $ git-hg clone http://some/random/hg/repo [local-git-repo-name]
  

• Fetch updates from the hg repo:

    $ git-hg fetch
  

  or optionally:

    $ git-hg pull # same as git-hg-fetch && git merge hg/branch_name
  

• Checkout a new branch from hg:

    $ git-hg checkout branch_name
  

• Push changes back to hg, optionally to a specific destination:

    $ git-hg push [destination]
  

Structure

.git/hgcheckout - contains a bare mercurial checkout of the specified repo

.git/hgremote - contains a bare git repo clones from the mercurial one, this is added as a remote called "hg" in the base repo
