Ensure that your Pelican plugin is called at the right time, every time.

Love Pelican but hate that your finalization plugin isn't always called in the right order? Don't let your plugin get lost in the shuffle of the finalized signal! pelican-granular-signals adds new finalization signals that guarantee your plugin is called at the right time, every time.

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.

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"])

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.
