Any complete GUI interface for Mercurial?

hg view is installed as part of the mercurial package, but not enabled by default to keep the package from depending on the tk toolkit. Install tk8.5, and the add the following to your "$HOME/.hgrc" file:

[extensions]
hgk=

Launch by running hg view in the repository folder.

Add the following PPAs to your Software Sources, instructions are at the link endpoints:

https://launchpad.net/~tortoisehg-ppa/+archive/releases

https://launchpad.net/~mercurial-ppa/+archive/releases

Or do it via the command line.

ppa:tortoisehg-ppa/releases (Click here for instructions on using PPAs.)

ppa:mercurial-ppa/releases (Click here for instructions on using PPAs.)

$ sudo apt-add-repository ppa:tortoisehg-ppa/releases
$ sudo apt-add-repository ppa:mercurial-ppa/releases

Install tortoisehg, and tortoisehg-nautilus if you want nautilus integration.

$ sudo apt-get install tortoisehg tortoisehg-nautilus

Use hgtk as though it were the usual hg command to get a GUI interface for each command (e.g. hgtk status), or use the interface provided in nautilus if you installed the requisite package.

meld does a pretty decent job. Just install it like this:

sudo apt-get install meld

And run it with:

meld

Then select "Version control view" and point it at the directory with your repository. It will show you all the changed files and you can view a visual diff by double clicking the file.
