Key Mapper

A Linux tool to change and program the mapping of your input device buttons.

Ubunut/Debian Manjaro/Arch Git


## Usage To open the UI to modify the mappings, use: ```bash key-mapper-gtk ``` You can also start it via your applications menu. To keep injecting the mapping after closing the window, the daemon needs to be running. If it doesn't already after logging in, you can use: ```bash key-mapper-service ``` It works with both Wayland and X11. ## Macros It is possible to write timed macros into the center column: - `k(1).k(2)` 1, 2 - `r(3, k(a).w(500))` a, a, a with 500ms pause - `m(Control_L, k(a).k(x))` CTRL + a, CTRL + x Documentation: - `r` repeats the execution of the second parameter - `w` waits in milliseconds - `k` writes a single keystroke - `m` holds a modifier while executing the second parameter - `.` executes two actions behind each other For a list of supported keystrokes and their names, check the output of `xmodmap -pke` ## Installation #### Ubunut/Debian ```bash dpkg -i $(wget TODO) usermod -a -G input $USER usermod -a -G plugdev $USER ``` #### Manjaro/Arch TODO ```bash pacaur -S key-mapper-git ``` #### Git ```bash git clone https://github.com/sezanzeb/key-mapper.git cd key-mapper sudo python3 setup.py install usermod -a -G input $USER usermod -a -G plugdev $USER ``` Depending on how those packages are called in your distro, you need the following dependencies: `python3-setuptools` `python3-evdev` `python3-dbus` ## Tests ```bash pylint keymapper --extension-pkg-whitelist=evdev sudo python3 setup.py install && python3 tests/test.py ``` ## Roadmap - [x] show a dropdown to select valid devices - [x] creating presets per device - [x] renaming presets - [x] show a mapping table - [x] make that list extend itself automatically - [x] read keycodes with evdev - [x] inject the mapping - [x] keep the system defaults for unmapped buttons - [x] button to stop mapping and using system defaults - [x] highlight changes and alert before discarding unsaved changes - [x] automatically load presets on login for plugged in devices - [x] make sure it works on wayland - [x] support timed macros, maybe using some sort of syntax - [ ] add to the AUR, provide .deb file - [ ] automatically load presets when devices get plugged in after login
