Is there a way to determine the Bazaar directory programmatically? If there is a bazaar command to determine the plugin directory, this would be the best solution.

Bazaar plugins are searched for in the following directories: 

* <pythonlib>/site-packages/bzrlib/plugins/ 
      (where <pythonlib> is something like usr/lib/python2.4, 
       depending on your installation)

* $HOME/.bazaar/plugins/

You can set the bazaar plugins directory via BZR_PLUGIN_PATH environement variable, also.

According to the bazaar website, user plugins are looked for in ~/.bazaar/plugins by default, but may be overridden by the environment variable BZR_PLUGIN_PATH. So test if this variable is set, otherwise return the default. In python:

import os
user_plugin_path = os.environ.get('BZR_PLUGIN_PATH', '~/.bazaar/plugins')

Edit: this works for unix based systems, for windows the uses plugin path is $APPDATA/bazaar/2.0/plugins.

The system wide plugin is in bzrlib/plugins, see Installing a plugin down the page here. Use distutils to get the prefix (e.g. /usr/lib/python2.4/site-packages/bzrlib/plugins/) :

from distutils.sysconfig import get_python_lib
global_plugin_path = os.path.join(get_python_lib(), 'bzrlib/plugins')

(Thanks to The MYYN for providing the other documentation page)

Have a look at the Bazaar configuration: output of bzr version. Also see function show_version in bzrlib/version.py.

For the configuration directory use:

from bzrlib import config
print config.config_dir()

Or, for the user plugin path (see bzrlib/plugin.py):

from bzrlib import plugin
print plugin.get_user_plugin_path()

For a full list of plugin paths:

from bzrlib import plugin
print plugin.get_standard_plugins_path()

  • All three answers are correct and its difficult to choose which one is the most correct "answer", but i did need a way to get to the version via the bazaar command rather than the internal api. I didn't mention that i was using java not python to get this directory. So I'm going to have to mark this as the anwer :) – Craig Dec 07 '09 at 20:20
  • If you need this available as output of bzr command you can write very simple bzr plugin for this. – bialix Dec 08 '09 at 07:47
  • Or even just run python with the snippet I've provided. – bialix Dec 08 '09 at 07:48
  • I want to install the Bazaar xmloutput plugin when the user installs qbzr-eclipse plugin. So it might not be such a bad idea to run your python script as a Process from java and use the output to determine the path of the user's plugin directory – Craig Dec 08 '09 at 20:37

If you have bzr installed in your system you can use following Python snippet to get the list of directories where bzr looking for plugins:

 >>> import os
 >>> from bzrlib import plugin
 >>> list_of_bzr_plugins_paths = [os.path.abspath(p) 
         for p in plugin.get_standard_plugins_path()]
