Walker

Walker is a centralized search interface and application launcher designed to find and start installed software, system tools, and local files. It functions as a single entry point for executing desktop applications, running shell commands, and managing system scripts.

The project uses a provider-based plugin architecture to extend its capabilities via independent modules. It allows for deep visual and behavioral customization through CSS styling, XML-defined layout templates, and layered configuration overrides.

The system includes integrated productivity tooling for mathematical calculations, web searches, clipboard history management, and special character insertion. It further covers system administration tasks such as managing active windows, controlling hardware peripherals, and handling system packages.

Features

Keyboard-to-Action Mappings - Maps keyboard modifiers and keys to internal system events to trigger specific application behaviors.

Window Listing - Lists all currently open windows and allows the user to shift focus to a selected application.

Background Services - Provides a resident background process to ensure the launcher interface appears instantly without startup delay.

Unified Productivity Entry Points - Combines task tracking, clipboard history, and window management into a single entry point to minimize application switching.

Dynamic Selection Menus - Generates selectable lists at runtime that return the user's choice to the system for execution.

Daemonized Process Execution - Operates as a background daemon to eliminate latency and provide immediate access to the search interface.

Keybinding Configurations - Allows users to map specific keyboard combinations and modifiers to trigger internal application actions.

Mathematical Calculators - Integrates a mathematical calculator to evaluate expressions and perform arithmetic directly within the search interface.

System Package Managers - Interfaces with system package managers to search, install, and remove software from repositories.

Web Search Integrations - Interfaces with configured external search engines to retrieve live web information directly from the launcher.

Hardware Control Interfaces - Provides a graphical interface to manage Bluetooth connections and sound input/output devices.

System Hardware Controllers - Controls system hardware settings and peripherals, such as Bluetooth devices, through the launcher interface.

Item Action Handlers - Maps specific keys or inputs to a variety of behaviors, such as executing shell commands or shifting window focus.

Daemonized Process Persistence - Operates as a background daemon to eliminate startup latency and provide an instant search interface.

Desktop Behavior Configuration - Allows customization of window positioning, interaction rules, and input handling for the desktop interface.

Custom Provider Menus - Enables the creation of static or dynamic selectable lists and actions via a provider-based system.

Interface Layout Customization - Enables the definition of visual structures and column displays for individual list items in the interface.

Dynamic Selection Lists - Displays dynamic selection interfaces that return the chosen option to the calling process for execution.
