Bazaar

Enhance/extend bzr-keywords (or any other plugin)

Asked by anurag uniyal

I need to add few more keywords to bzr-keywords plugin, going thru it src it says

# The registry of keywords. Other plugins may wish to add entries to this.
keyword_registry = registry.Registry()

so can i create a small plugin and do something like this

from bzrlib.plugins.keywords import keyword_registry

keyword_registry.register('Revision-Number',
    lambda c:get_revno(c))
keyword_registry.register('Tag',
    lambda c:get_tag(c))

I am not sure I can rely on my plugin code always being called?
or bzrlib.plugins.keywords will correctly import from my plugin?

Where I can see plugin writing and loading documentation?

^- this should work.
The code is in "bzrlib/plugin.py". We set bzrlib.plugins.__path__ such
that you should be able to "import bzrlib.plugins.*".

The basic rules are such that:

1) Plugin load order is not guaranteed
2) Plugins should be able to import other plugins that have not been
loaded yet (because of __path__). So if you depend on .keywords, you
should be able to get access to it.
3) All plugins in the path will get loaded eventually.
