pyFlowLauncher

pyFlowLauncher is an API that allows you to quickly create plugins for Flow Launcher!

Installation

Install via pip:

python -m pip install pyflowlauncher[all]

Usage

Basic plugin

A basic plugin using a function as the query method.

from pyflowlauncher import Plugin, Result

plugin = Plugin()


@plugin.on_method
def query(query: str):
    yield Result(
        title="This is a title!",
        subtitle="This is the subtitle!",
        icon="icon.png"
    )


plugin.run()

Methods decorated with @plugin.on_method can yield one or more Result objects, return a list of Result objects, or return a single Result — the framework normalizes all forms into the correct response automatically.

Advanced plugin

A more advanced usage using a Method class as the query method.

from pyflowlauncher import Plugin, Result, Method
from .models.json_rpc import JsonRPCResponse

plugin = Plugin()


class Query(Method):

    def __call__(self, query: str) -> JsonRPCResponse:
        r = Result(
            title="This is a title!",
            subtitle="This is the subtitle!"
        )
        self.add_result(r)
        return self.return_results()

plugin.add_method(Query())
plugin.run()

Context menus

Plugin ships with a built-in context_menu method: put Result objects in a result's context_data and they become that result's context menu — no handler code required.

from pyflowlauncher import Plugin, Result

plugin = Plugin()


@plugin.on_method
def query(query: str):
    yield Result(
        title="This is a title!",
        subtitle="Right-click me for a context menu.",
        context_data=[
            Result(title="This is a context menu item!"),
            Result(title="So is this!"),
        ],
    )


plugin.run()

Menu items are full Result objects, so they can carry actions via add_action() just like query results.

If you need more control (for example, building the menu lazily when it is opened), register your own context_menu — it replaces the built-in one:

@plugin.on_method
def context_menu(context_data):
    yield Result(title=f"Menu for {context_data[0]}")
