lisgd

Lisgd (libinput synthetic gesture daemon) lets you bind gestures based on libinput touch events to run specific commands to execute. For example, dragging left to right with one finger could execute a particular command like launching a terminal. Directional L-R, R-L, U-D, and D-U gestures and diagnol LD-RU, RD-LU, UR-DL, UL-DR gestures are supported with 1 through n fingers.

Unlike other libinput gesture daemons, lisgd uses touch events to recognize synthetic swipe gestures rather than using the libinput's gesture events. The advantage of this is that the synthetic gestures you define via lisgd can be used on touchscreens, which normal libinput gestures don't support.

This program was built for use on the Pinephone; however it could be used in general for any device that supports touch events, like laptop touchscreens or similar. You may want to adjust the threshold depending on the device you're using.

Configuration

Configuration can be done in two ways:

  1. Through a suckless style config.h; see the config.def.h
  2. Through commandline flags which override the default config.h values

Suckless-style config.h based configuration

Copy the example config.def.h configuration to config.h.

Commandline flags based configuration

Flags:

  • -d [devicenodepath]: Defines the dev filesystem device to monitor
    • Example: lisgd -d /dev/input/input1
  • -g [nfingers,gesture,edge,distance,command]: Allows you to bind a gesture wherein nfingers is an integer, gesture is one of {LR,RL,DU,UD,DLUR,URDL,ULDR,DLUR}, edge is one of * (any), N (none), L (left), R (right), T (top), B (bottom), TL (top left), TR (top right), BL (bottom left), BR (bottom right) and distance is one of * (any), S (short), M (medium), L (large). command is the shell command to be executed. The -g option can be used multiple times to bind multiple gestures.
    • Single Gesture Example: lisgd -g "1,LR,*,*,notify-send swiped lr"
    • Multiple Gestures Example: lisgd -g "1,LR,*,*,notify-send swiped lr" -g "1,RL,R,*,noitfy-send swiped rl from right edge"
  • -m [timeoutms]: Number of milliseconds gestures must be performed within to be registered. After the timeoutms value; the gesture won't be registered.
    • Example: lisgd -m 1200
  • -o [orientation]: Number of 90-degree rotations to translate gestures by. Can be set to 0-3. For example using 1; a L-R gesture would become a U-D gesture. Meant to be used for screen-rotation.
    • Example lisgd -o 1
  • -r [degrees]: Number of degrees offset each 45-degree interval may still be recognized within. Maximum value is 45. Default value is 15. E.g. U-D is a 180 degree gesture but with 15 degrees of leniency will be recognized between 165-195 degrees.
    • Example: lisgd -r 20
  • -t [threshold_units]: Threshold in libinput units (pixels) after which a gesture registers. Defaults to 300.
    • Example: lisgd -t 400
  • -v: Verbose mode, useful for debugging
    • Example: lisgd -v

Usage

I spent an embarrassingly long amount of time trying to work out why this wasn't working. Be sure that your user is in the input group before running it.
