I don’t know about you, but I was really bored about inserting my password again and again when pulling hg based projects.
Since I’m using Gnome, I decided to check if it was possible to integrate Mercurial with the Gnome Keyring.
Just download the extension and install it, by adding the following line under [extensions] in your .hgrc file:
hggnome-keyring = [PATH_TO_EXTENSION]/hggnome-keyring.py
When pulling from a hg repo, the system will prompt you for the password just for the first time :)
