lillinput

About

lillinput is a small utility written in Rust for connecting [libinput] gestures into: * commands for the [i3] tiling window manager IPC interface * shell commands

Project status

Please be aware that this project is in beta, and was started for scratching a specific itch - allowing three-finger swipe for changing between workspaces in i3 under a personal setup. It aims to stay small (hence the [name]) and biased towards custom needs (and a bit of a Rust playground).

Usage

Upon invocation, lillinput will listen to libinput events until stopped. By default, the i3 action will be enabled, with the workspace next configured for the "three finger right swipe" gesture, and the workspace prev for the "three finger left swipe" gesture.

The full list of options can be retrieved via:

bash $ lillinput --help

        actions the four-finger swipe down

    --four-finger-swipe-left <FOUR_FINGER_SWIPE_LEFT>...
        actions the four-finger swipe left

    --four-finger-swipe-right <FOUR_FINGER_SWIPE_RIGHT>...

-t, --threshold <THRESHOLD>
        minimum threshold for displacement changes

    --three-finger-swipe-down <THREE_FINGER_SWIPE_DOWN>...
        actions the three-finger swipe down

    --three-finger-swipe-left <THREE_FINGER_SWIPE_LEFT>...
        actions the three-finger swipe left

    --three-finger-swipe-right <THREE_FINGER_SWIPE_RIGHT>...
        actions the three-finger swipe right

    --three-finger-swipe-up <THREE_FINGER_SWIPE_UP>...

-v, --verbose
        Level of verbosity (additive, can be used up to 3 times)

-V, --version
        Print version information

```

Configuring the swipe actions

Each --{number}-finger-swipe-{direction} argument accepts one or several "actions", in the form {type}:{command}. For example, the following invocation specifies two actions for the "three finger swipe up": moving to the next workspace in i3, and creating a file.

bash $ lillinput --three-finger-swipe-up "i3:workspace next" --three-finger-swipe-up "command:touch /tmp/myfile"

Currently, the available action types are i3 and command.

Using a configuration file

The configuration from the application can be read from a configuration file. By default, the following sources will be read in order:

/etc/lillinput.toml
${XDG_HOME}/lillinput/lillinput.toml
${CWD}/lillinput.toml

Alternatively, a different file can be specified via the --config-file argument. If specified, any other command line arguments will take precedence over values read from the configuration file.

The format of the configuration can be found in the [sample configuration file]: ```toml verbose = 0 seat = "seat01" threshold = 20.0 enabledactiontypes = ["i3"]

[actions] three-finger-swipe-right = ["i3:workspace next"] three-finger-swipe-left = ["i3:workspace prev"] three-finger-swipe-up = [] three-finger-swipe-down = [] four-finger-swipe-right = [] four-finger-swipe-left = [] four-finger-swipe-up = [] four-finger-swipe-down = [] ```

This create relies heavily on the wonderful work on the [input] and [i3ipc] crates (among others) - kudos to their maintainers for making them available.

Outside rust, the following projects provide a more complete solution for using libinput gestures: * [libinput-gestures] * [fusuma] * [geebar-libinput]
