hyprKCS - Hyprland keybind manager

Source: Dev.to

Overview

Ever forget your own keybinds? Tired of grepping through multiple config files just to change a workspace shortcut?
hyprKCS is a native, fast GUI written in Rust & GTK4. It parses your Hyprland config (including recursively sourced files) and provides a searchable, interactive dashboard for your system.

Features

• Fuzzy Search – Find actions instantly (e.g., type resize or volume).
• Add, Edit & Delete – Full CRUD support for your keybinds directly from the UI.
• Key Recorder – Click “Record” and press the keys instead of typing SUPER + SHIFT + Q.
• Deep Parsing – Reads source = … directives recursively across your entire setup.
• Native UI – Built with Libadwaita to match your system theme (dark/light mode) seamlessly.
• Direct Control – Execute and test binds directly from the UI via hyprctl.
• Conflict Wizard – Automatically detects duplicate binds and guides you through resolving them interactively. No more hunting for that one duplicate SUPER + Q.
• Massive Optimization – Refactored parser logic and switched to the jemalloc allocator; now lighter and faster than ever.
• Smart Backups – One‑click backup that recursively saves your main config and all sourced files into a timestamped directory.

Technical Details

• Recursive Parser – Custom regex‑based parser that handles variable resolution ($mainMod) and recursive file sourcing.
• Memory Optimization – Switched to tikv-jemallocator on Linux and optimized the parsing algorithm (removed O(n²) sorting), resulting in a negligible memory footprint (~20–30 MB RSS in release mode).
• Layer Shell – Uses gtk4-layer-shell to render as a proper overlay application that respects Hyprland’s window rules.
