Input

sweets.input(...) configures physical libinput pointer devices. On startup, hot reload, and for newly connected devices, Sweets resets configurable fields to libinput defaults, applies the global input block, then applies matching selector blocks in config order.

sweets.input({
  accel_speed = 0.0,
})

sweets.input("touchpad", {
  tap = true,
  natural_scroll = true,
  disable_while_typing = true,
})

sweets.input("mouse", {
  natural_scroll = false,
  accel_profile = "flat",
})

sweets.input("name:ELAN", {
  accel_speed = -0.25,
})

Selectors

Call sweets.input({ ... }) with no selector to target every device, or sweets.input(selector, { ... }) to target a subset:

For example, this keeps natural scrolling only on the touchpad while the USB mouse keeps normal wheel direction:

sweets.input({
  accel_speed = 0.0,
})

sweets.input("touchpad", { natural_scroll = true })
sweets.input("mouse", { natural_scroll = false })

Live tuning

Use sweetctl input TEXT to inspect one unique device, then tune a setting without reloading the configuration:

sweetctl input ELAN accel_speed -0.25
sweetctl input ELAN natural_scroll true
sweetctl input "Logitech USB Optical Mouse" accel_profile flat

The supported setting names and values are the same as the options below. These changes are temporary: saving or reloading Lua, reconnecting the device, or restarting Sweets resets it to the configured/default state. Once a value feels right, add it to the matching sweets.input(...) block.
