# Running

Installation:

```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
```

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
sudo key-mapper-service
```

To open the UI to modify the mappings, use:

```bash
sudo key-mapper-gtk
```

You can also start it via your applications menu.

# Dependencies

Depending on how those packages are called in your distro:

`python3-distutils-extra` `python3-evdev` `python3-dbus`

It works with both Wayland and X11.

# Tests

```bash
pylint keymapper --extension-pkg-whitelist=evdev
sudo python3 setup.py install && python3 tests/test.py
```
