caps2esc

Remap CAPS LOCK to ESC in Linux systems.

Overview

This is inspired by / based on evremap by wez.

Uses libevdev to grab exclusive access to the input device, reads input events, remaps CAPS LOCK to ESC and writes them back to a virtual output device.

Example Usage

List devices

sudo zig-out/bin/caps2esc --list-devices

Remap key

sudo zig-out/bin/caps2esc --device 'device-name'

Building from Source
