rusty-keys ========== [![Build Status](https://ci.moparisthe.best/job/moparisthebest/job/rusty-keys/job/master/badge/icon%3Fstyle=plastic)](https://ci.moparisthe.best/job/moparisthebest/job/rusty-keys/job/master/) low level keyboard mapper for linux and windows, with advanced caps lock and shift swapping behavior This is the only keymapper I am aware of capable of implementing this layout, which I call Unix Programmer's Dvorak, which has been my daily driver since 2014: ![Unix Programmer's Dvorak](https://www.moparisthebest.com/kbs/programmer-dvorak-NoSecondary-NumpadStandard-NoSwap-StandardNums-SwapAt-SwapPipe.svg) The Problem ----------- If you ever have mapped keys on linux, you know that there is the console keymap (loadkeys) and the X keymap (setxkbmap), also things like SDL and Virtualbox grab the input directly and respect no maps. Lastly I want to revert to QWERTY when holding ctrl so ctrl+c works just like normal, without remapping all programs to ctrl+j. Linux keymaps cannot do this either. The Solution ------------ 1. Grab a keyboard device directly so only we can read events from it. 2. Create a new keyboard input device with uinput, this looks identical to any other keyboard device to anything running on the box. 3. Read input_events from the real device, map them, send them to our created device. This solution is what rusty-keys implements, it works in ttys, in X, in Wayland, in virtualbox even running windows or whatever, on SDL games, it will work literally everywhere, because rusty-keys just creates a regular keyboard. How to run ---------- When ran, it will read a keymap.toml configuration file, refer to example and tweak to suit. ``` Usage: rusty-keys [options] [device_files...] Options: -h, --help prints this help message -v, --version prints the version -c, --config FILE specify the keymap config file to use (default: /etc/rusty-keys/keymap.toml) ``` when ran without specifying input devices, it maps all currently connected keyboards, and watches /dev/input/ with inotify and starts mapping any new keyboards that are plugged in forever, until you kill it: `rusty-keys` or you can specify one or multiple input devices, and it will run until all are disconnected, then stop: `rusty-keys /dev/input/event0` or `rusty-keys /dev/input/event0 /dev/input/event2` An example systemd service is in systemd/rusty-keys.service, enable it to have mapped keyboards all the time.
