Development

It's easy to write your own plugin by making a python package and then indicating it's name as the plugin name.

Contributing guidelines

Writing plugins

Plugins can be loaded with full python module path, eg: "mymodule.pyprlandplugin", the loaded module must provide an Extension class.

Check the interface.py file to know the base methods, also have a look at the example below.

To get more details when an error is occurring, use pypr --debug <log file path>, it will also display the log in the console.

Note

To quickly get started, you can directly edit the experimental built-in plugin. In order to distribute it, make your own Python package or trigger a pull request. If you prefer to make a separate package, check the examples's package

The Extension interface provides a couple of built-in attributes:

• config : object exposing the plugin section in pyprland.toml
• notify ,notify_error, notify_info : access to Hyprland's notification system
• hyprctl, hyprctlJSON : invoke Hyprland's IPC system

Important

Contact me to get your extension listed on the home page

Workflow

Instead of killing the existing pypr, use:

pypr exit

The "hidden" exit command will exit cleanly, removing the IPC socket, so you can start pypr again without any complication.

Then you can run pypr in the terminal, getting the logs in real time and in a log file, ^C will also exit cleanly so you can re-run the command with no hassle:

pypr --debug /tmp/output.log

Creating a plugin

from .interface import Plugin


class Extension(Plugin):
    " My plugin "

    async def init(self):
        await self.notify("My plugin loaded")

Adding a command

Just add a method called run_<name of your command>, eg with "togglezoom" command:

zoomed = False

async def run_togglezoom(self, args):
    """ this doc string will show in `help` to document `togglezoom`
    But this line will not show in the CLI help
    """
  if self.zoomed:
    await self.hyprctl('misc:cursor_zoom_factor 1', 'keyword')
  else:
    await self.hyprctl('misc:cursor_zoom_factor 2', 'keyword')
  self.zoomed = not self.zoomed

Reacting to an event

Similar as a command, implement some async def event_<the event you are interested in> method.

Code safety

Pypr ensures only one run_ or event_ handler runs at a time, allowing the plugins code to stay simple and avoid the need for concurrency handling. However, each plugin can run its handlers in parallel.

Re-usable code

from ..common import state, CastBoolMixin

• state provides a couple of handy variables so you don't have to fetch them, allow optimizing the most common operations
• Mixins are providing common code, for instance the CastBoolMixin provides the cast_bool method to your Extension.

If you want to use menus, then the MenuMixin will provide:

• menu to show a menu
• ensure_menu_configured to call before you require a menu in your plugin

Example

You'll find a basic external plugin in the examples folder.

It provides one command: pypr dummy.

Read the plugin code

It's a simple python package. To install it for development without a need to re-install it for testing, you can use pip install -e . in this folder. It's ready to be published using poetry publish, don't forget to update the details in the pyproject.toml file.

Usage

Ensure you added pypr_examples.focus_counter to your plugins list:

[pyprland]
plugins = [
  "pypr_examples.focus_counter"
]

Optionally you can customize one color:

["pypr_examples.focus_counter"]
color = "FFFF00"

Friendly documentation

Run:

tox -e doc

Workflow

Kill existing pypr

• pkill pypr
• rm /tmp/hypr/$HYPRLAND_INSTANCE_SIGNATURE/.pyprland.sock

Run / stop / repeat

You can now run pypr --debug /tmp/pypr.log, it will also show the logs and print() in the terminal.

Press Control+C and repeat the last command to test your newly changed code.
