hgcfg extension for mercurial
Displays or modifies local, user, and global configuration.
This extension provides command-line access to hg configuration values stored in hgrc files. You can use this extension to view and change configuration values, show which configuration files are used by hg, and edit any of these files from the command-line.
Three commands are provided by this extension:
- Set or query config values in local, user, or global hg config files
- List all items in a given config section
- List all config files for a repository
EDITORto edit local, user, or global config file
- Delete or comment-out old values when overwriting
- Colorized when
colorextension is enabled
- Backwards compatible with "alu"'s
hgconfigextension (through rev 80f98d6)
Check how a configuration key is being set
$ hg cfg ui.username --verbose
values found for ui.username in global/local/user config: bmearns (user) C:\Users\bmearns\mercurial.ini * metalark (local) C:\Users\bmearns\.hgext\hgconfig\.hg\hgrc
Change a configuration key in the local (repo) config file
$ hg cfg ui.username "kingcobra"
$ hg cfg ui.username --verbose values found for ui.username in global/local/user config: bmearns (user) C:\Users\bmearns\mercurial.ini * kingcobra (local) C:\Users\bmearns\.hgext\hgconfig\.hg\hgrc
Edit user config file
$h g editcfg --user multiple config files to choose from, please select:  C:\Users\bmearns\.hgrc  C:\Users\bmearns\mercurial.ini which file do you want to edit:  1 editing config file 
Uses configured editor to edit the specified file, by way of a temp file, like commit messages.
List available config files
$ hg listcfgs ro globalC:\Program Files\TortoiseHg\hgrc.d\EditorTools.rc ro globalC:\Program Files\TortoiseHg\hgrc.d\Mercurial.rc ro globalC:\Program Files\TortoiseHg\hgrc.d\MergePatterns.rc ro globalC:\Program Files\TortoiseHg\hgrc.d\MergeTools.rc rw globalC:\Program Files\TortoiseHg\hgrc.d\Paths.rc ro globalC:\Program Files\TortoiseHg\hgrc.d\TerminalTools.rc rw user C:\Users\bmearns\mercurial.ini ! user C:\Users\bmearns\.hgrc rw local C:\Users\bmearns\.hgext\hgconfig\.hg\hgrc
! indicates the file is not present,
ro indicates the file is not writeable by the current user,
rw indicates that it is writeable.
To install this extension, download the files in the hgext directory to your system
and edit your hgrc config file to add the
hgcfg.py file as an extension:
[extensions] hgcfg = /path/to/hgcfg/hgext/hgcfg.py
You can just as well clone the entire [hgext repository][https://bitbucket.org/bmearns/hgcfg] and use it the same way, just make sure to point
the extension at
It doesn't matter where you place the files, but a common place to put them is under
~/.hgext (on Windows, this would be
C:\Users\USERNAME\.hgext in Windows 7).
The following shows the results of issuing the
hg listcfgs command in conjunction with the built-in

This extension also provides a basic API that other mercurial extensions can use to poke around and modify configuration files, instead of hacking on the text themselves. Although this API is not yet documented well, you can take a look at the available functions in hgcfg.py. Most of them even have useful docstrings.
To access the API from another extension, use the following python code:
import mercurial.extensions hgcfg = mercurial.extensions.find('hgcfg')
hgcfg variable will then hold a
module object, which you can use just like an imported module. For instance:
section = "ui" key = "username" value = "newusername" scopes = ["local", "user"] hgcfg.writevalue(ui, repo, section, key, value, scopes)
This extension was originally forked from the http://mercurial.selenic.com/wiki/ConfigExtensionCommandLine">
extension (frequently just called "config") by BitBucket user "alu".
Most of the core functionality comes from that extension, but some additional features have been added.
hgcfg extension retains backwards compatibility with the alu's
hgconfig extension, so you can
seamlessly replace that extension with this one.
There is also another but developmentally unrelated extension called
by Steve Borho which serves many of the same purposes.
However, this extension hasn't been active since 2007 and is marked on its wiki page as "defunct".
