A plugin is an external component for Bazaar that is typically made by
10
third parties. A plugin is capable of augmenting Bazaar by adding new
11
functionality. A plugin can also change current Bazaar behavior by
12
replacing current functionality. Plugins often work as a way for
13
developers to test new features for Bazaar prior to inclusion in the
14
official codebase. Plugins can do a variety of things, including

We keep our list of plugins on the http://bazaar-vcs.org/BzrPlugins page.

How to Install a plugin
24
=======================
25
Installing a plugin is very easy! One can either install a plugin
26
system-wide or on a per user basis. Both methods involve creating a
27
``plugins`` directory. Within this directory one can place plugins in
28
subdirectories. For example, ``plugins/bzrtools/``.
30
Two locations are currently checked: the bzrlib/plugins directory
31
(typically found in ``/usr/lib/python2.4/site-packages/bzrlib/plugins/``) and
32
``$HOME/.bazaar/plugins/``.
34
One can additionally override the home plugins by setting the environment
35
variable ``BZR_PLUGIN_PATH`` to a directory that contains plugins. The
36
installation of a plugin can be checked by running ``bzr plugins`` at
37
any time. New commands can be seen by running ``bzr help commands``.
38
The commands provided by a plugin are shown followed by the name of the
41
Plugins work particularly well with Bazaar branches. For example, to
42
install the bzrtools plugins for your main user account, one can perform
45
bzr branch http://panoramicfeedback.com/opensource/bzr/bzrtools
46
~/.bazaar/plugins/bzrtools
48
When installing plugins the directories that you install them in must
49
be valid python identifiers. This means that they can only contain
50
certain characters, notably they cannot contain hyphens (``-``). Rather
51
than installing ``bzr-gtk`` to ``~/.bazaar/plugins/bzr-gtk``, install it
52
to ``~/.bazaar/plugins/gtk``.
20
We keep our list of plugins on the http://bazaar-vcs.org/PluginRegistry page.
58
26
but most plugins supply new commands.
60
28
To create a command, make a new object that derives from
61
``bzrlib.commands.Command``, and name it ``cmd_foo``, where foo is the name of
29
`bzrlib.commands.Command`, and name it cmd_foo, where foo is the name of
62
30
your command. If you create a command whose name contains an underscore,
63
31
it will appear in the UI with the underscore turned into a hyphen. For
64
example, `cmd_baz_import` will appear as `baz-import`. For examples of how
65
to write commands, please see ``builtins.py``.
32
example, "cmd_baz_import" will appear as "baz-import". For examples of how
33
to write commands, please see builtins.py.
67
35
Once you've created a command you must register the command with
68
``bzrlib.commands.register_command(cmd_foo)``. You must register the
69
command when your file is imported, otherwise bzr will not see it.
36
`bzrlib.commands.register_command(cmd_foo)`. You must register the command
37
when your file is imported, otherwise bzr will not see it.
71
Bzr will scan ``bzrlib/plugins`` and ``~/.bazaar/plugins`` for plugins
72
by default. You can override this with ``BZR_PLUGIN_PATH``. Plugins
73
may be either modules or packages. If your plugin is a single file,
74
you can structure it as a module. If it has multiple files, or if you
75
want to distribute it as a bzr branch, you should structure it as a
76
package, i.e. a directory with an ``__init__.py`` file.
39
Bzr will scan **bzrlib/plugins** and **~/.bazaar/plugins** for plugins by
40
default. You can override this with **BZR_PLUGIN_PATH**. Plugins may be
41
either modules or packages. If your plugin is a single file, you can
42
structure it as a module. If it has multiple files, or if you want to
43
distribute it as a bzr branch, you should structure it as a package, i.e. a
44
directory with an **__init__.py** file.

46
Please feel free to contribute your plugin to BzrTools, if you think it
79
47
would be useful to other people.
