New Pelican signals

When pelican-granular-signals is installed, the following signals will be called immediately after the finalized signal:

• sitemap

• optimize

• minify

• compress

• deploy

Each signal will be sent with the same argument that is sent to the finalized signal.

Connecting to granular signals

Your plugin must register with blinker directly. Here’s a complete example:

import blinker

import pelican.plugins.granular_signals


def register():
    # This line is highly recommended so users
    # don't have to update their configurations.
    pelican.plugins.granular_signals.register()

    # Connect your awesome plugin to a granular signal.
    blinker.signal("deploy").connect(deploy_site)


# -----------------------------------------------------
# Put your awesome plugin code here.

import subprocess

def deploy_site(instance):
    subprocess.run(instance.settings["DEPLOY_COMMAND"])

Helping users out

To make life easier for users, consider taking these two steps:

1. List pelican-granular-signals as a dependency so it will be automatically installed with your plugin.

2. When Pelican calls your plugin’s register() function, call pelican.plugins.granular_signals.register().

Pelican 4.5 introduced a new, automatic plugin loading feature and pelican-granular-signals is designed to work with this feature! Unfortunately, if a user specifies which plugins to load in their configuration file then automatic plugin loading will be disabled. It is therefore recommended that you call pelican.plugins.granular_signals.register() in your plugin’s register() function.

pelican.plugins.granular_signals.register() can be called multiple times without creating any problems.
