KRunner Dart

A user-friendly API for KDE's KRunner application.

With KRunner Dart you can create plugins for KDE's KRunner application in an easy and sane way. The API is designed to be type safe, null safe, and easy to use.

Unlike the C++ or Python APIs, KRunner Dart provides code completion and documentation in tooltips for a better development experience.

Usage

Creating plugins

import 'package:krunner/krunner.dart';

Future<void> main() async {
  /// Create a runner instance.
  final runner = KRunnerPlugin(
    identifier: 'com.example.plugin_name',
    name: '/plugin_name',
    matchQuery: (String query) async {
      /// If the KRunner query matches exactly `hello` we return a match.
      if (query == 'hello') {
        return [
          QueryMatch(
            id: 'uniqueMatchId',
            title: 'This is presented to the user',
            icon: 'checkmark',
            rating: QueryMatchRating.exact,
            relevance: 1.0,
            properties: QueryMatchProperties(subtitle: 'Subtitle for match'),
          ),
        ];
      } else {
        return []; // Empty response (no matches).
      }
    },
    retrieveActions: () async => [
      SecondaryAction(
        id: 'uniqueActionId',
        text: 'hoverText',
        icon: 'addressbook-details',
      ),
    ],
    runAction: ({required String actionId, required String matchId}) async {
      if (actionId == 'uniqueActionId') {
        print('User clicked secondary action!');
      }
    },
  );

  /// Start the runner.
  await runner.init();
}

Refer to the example directory for a complete example, including instructions for debugging and installing plugins.

For a real-world example of a plugin made with this API see VSCode Runner.
