Quickstart

In the mediagoblin repository, there's a sample plugin under mediagoblin/plugins/sampleplugin that you can use to get started with plugin creation. The simplest way to get up and running is to

  1. Follow HackingHowto#How_to_set_up_and_maintain_an_environment_for_hacking_with_virtualenv to set up a local virtualenv mediagoblin instance
    • run it with ./lazyserver.sh so you get debug output (if you run celeryd separately, you won't see logging.info from stuff run in celery tasks)
  2. cp -r mediagoblin/plugins/sampleplugin mediagoblin/plugins/myplugin (where "myplugin" is your plugin name)
  3. cp mediagoblin.ini mediagoblin_local.ini
  4. edit mediagoblin_local.ini and add [[mediagoblin.plugins.myplugin]] under the [plugins] section to enable your plugin

Now you can look at e.g. other core or non-core plugins for inspiration. See Available Plugins for non-core plugins.

Making an installable plugin

If you followed the steps above, you can use your plugin by copying it into the plugins folder; however, to get a plugin that is easily installable by users (e.g. with pip install myplugin), it should have a certain folder layout. A good example is the RDFa plugin. This uses a setup.py file to install the files under the mediagoblin_rdfa folder into the lib/ folder of your mediagoblin installation. If you've checked out both mediagoblin and mg-rdfa in the same folder, e.g. ~/src/, you can do
cd ~/src/mg-rdfa/
../mediagoblin/bin/python setup.py build
../mediagoblin/bin/python setup.py install
to install it to your mediagoblin instance.n
