Getting started with Indico plugins


Write a REAL, simple example of a plugin. Include link to Github repo.

Example plugin

The following is a minimal plugin that makes use of all capababilites of the plugin API. The display name of the plugin is defined by the first line of the docstring and the description by the rest of it. The plugin may override signal handlers to hook into Indico and aditionally run any initialization needed. For example, it will add some command to Indico CLI, extend the shell context and register some assets. Also, init is used to inject CSS and JS bundles outside of the plugin scope.

class ExamplePlugin(IndicoPlugin):
    """Example Plugin

    An example plugin that demonstrates the capabilities of the new Indico plugin system.

    settings_form = SettingsForm

    def init(self):
        super(ExamplePlugin, self).init()

    def get_blueprints(self):
        return blueprint

    def add_cli_command(self, manager):
        def example():
            """Example command from example plugin"""
            print 'example plugin says hi', current_plugin
            if self.settings.get('show_message'):
                print self.settings.get('dummy_message')

    def extend_shell_context(self, add_to_context):
        add_to_context('bar', name='foo', doc='foobar from example plugin', color='magenta!')

The plugin can specify its settings via a IndicoForm:

class SettingsForm(IndicoForm):
    dummy_message = StringField('Dummy Message')
    show_message = BooleanField('Show Message')

The plugin can also specify request handlers and templates. Templates will be loaded from a templates folder within your plugin folder. Your plugin can even load templates from other modules by prefixing the name of the template ‘other_plugin:example’ with render_template().

class WPExample(WPDecorated):
    def _get_body(self, params):
        return render_plugin_template('example.html', **params)

class RHExample(RH):
    def _process(self):
        return WPExample(self, foo=u'bar').display()

class RHTest(RH):
    def _process(self):
        return render_plugin_template('test.html')

blueprint = IndicoPluginBlueprint('example', __name__)
blueprint.add_url_rule('/example', 'example', view_func=RHExample)
blueprint.add_url_rule('/example/x', 'example', view_func=RHExample)
blueprint.add_url_rule('/test', 'test', view_func=RHTest)
