Using Mercurial extensions

Mercurial features an extension mechanism for adding new commands.

Extensions allow the creation of new features and using them directly from the main hg command line as if they were builtin commands.

2. Enabling an extension

To load an extension, you add it to the "extensions" section of your [http://www.selenic.com/mercurial/hgrc.5.html .hgrc] file.

Mercurial will scan the default python library path for a file named hgk.py if you set hgk empty:

[extensions]
hgk=

Extensions are usually located in the hgext directory, and that is the recommended directory to place them. In this case you can load them like:

[extensions]
hgext.hgk=

You can also specify an absolute path:

[extensions]
hgk=/usr/local/lib/hgk.py

Extensions can often be configured further in an extension specific section in the same configuration file.

See CategoryExtension for a more complete list and WritingExtensions for more information about the installation and writing of new extensions.
