Cedit
This extension is/is not distributed with Mercurial.
Author: Paul Lambert
Download site: http://bitbucket.org/paulitex/cedit/
Tested with: Mercurial >= 1.4.3
Overview
Command Line editor for Mercurial configuration files. Features both an interactive editor and an options parsing mode. Simplifies Mercurial configuration so that users never have to manually edit their hgrc / Mercurial.ini files, if they so choose.
Cedit does have a bootstrapping feature - you don't have to manually touch your configuration files to install this extension (unlike almost every other Mercurial extension). Simply run "python start.py" and you should be good to go.
NOTE TO WINDOWS USERS: To run the bootstrapping script it is required that you have python installed and in your path. It is not sufficient to have Mercurial installed. If you have Mercurial installed by not Python, you can still use the extension by manually adding it to you Mercurial.ini file.
Configuration
If you have just installed mercurial, this will get you going:
hg clone https://paulitex@bitbucket.org/paulitex/cedit/ cd cedit python start.py
