Features

• Keyboard Launchers - Launches applications, opens files, and runs commands by typing search queries without touching a mouse.
• Plugin-Based Architectures - Extends core functionality through dynamically loaded C++ and Python plugins integrated with the event loop.
• Application Launchers - Opens installed applications by typing their name into the search interface.
• Shell Command Execution - Runs shell commands directly from the search bar without opening a terminal window.
• Parallel Query Dispatchers - Dispatches user queries to all enabled handlers in parallel, then merges and ranks results by relevance.
• Functional Module Management - Loads, unloads, enables, and disables functional plugin modules at runtime through settings or query handlers.
• Directory-Based Plugin Discovery - Discovers and loads plugins by scanning designated directories for Python modules and C++ shared libraries.
• Application Launch Interfaces - Finds and opens installed applications by typing their name into a keyboard-driven search interface.
• Asynchronous Query Handlers - Processes user queries without blocking the main thread to maintain responsive keyboard input.
• Quick-Launch Application Interfaces - Opens files and launches applications by typing search queries into a keyboard-driven interface.
• Search-Based Application Launchers - Opens files, applications, and actions by typing a search query into a keyboard-driven interface.
• Plugin-Based Global Search - Contributes items to the launcher's global search results alongside other installed plugins.
• Python Plugin Integrations - Creates Python modules following a stub file interface to add custom search and action capabilities.
• Triggered Plugin Query Handlers - Responds to user queries with a custom list of items and actions when the plugin is explicitly triggered.
• Plugin Query Handlers - Processes user input through registered query handlers that return relevant results from various sources.
• Community Extension Installers - Adds new search sources and actions by installing community-maintained plugins through a simple API.
• Qt Plugin Development - Enables creating native C++ plugins with full access to Qt and the event loop for maximum performance.
• File System Navigators - Locates files on the system by matching typed queries against file names and paths.
• Keyboard Launcher Plugin Frameworks - Provides frameworks for developing both native C++ shared library plugins and Python modules to extend the launcher.
• CMake-Based Plugin Loaders - Creates shared library plugins that integrate with the launcher by implementing a plugin instance class and using CMake macros.
• File Search by Attribute - Finds files on the system by matching a typed query against file names and paths.
• Parallel Plugin Query Execution - Sends non-triggered input to all enabled handlers in parallel, then merges and sorts results by match and usage score.
• Usage-Based Scoring - Ranks search results by combining match quality with historical usage frequency to improve relevance over time.
• Query Fallback Chains - Implements a fallback handler chain that displays alternative results when primary handlers find no matches.
• Trigger-Based Input Routings - Routes input starting with a trigger exclusively to a specific handler that can set hints and add items asynchronously.
• Desktop Launchers - Keyboard-based launcher for the Linux desktop.
