plugins: add support for lua plugins to change evdev event streams This patch adds support for Lua scripts to modify evdev devices and event frames before libinput sees those events. Plugins in Lua are sandboxed and restricted in what they can do: no IO, no network, not much of anything else. A plugin is notified about a new device before libinput handles it and it can thus modify that device (changes are passed through to our libevdev context). A plugin can then also connect an evdev frame handler which gives it access to the evdev frames before libinput processes them. The example plugin included shows how to swap left/right mouse buttons: libinput:register({1}) function frame(device, frame) for _, v in ipairs(frame.events) do if v.usage == evdev.BTN_RIGHT then v.usage = evdev.BTN_LEFT elseif v.usage == evdev.BTN_LEFT then v.usage = evdev.BTN_RIGHT end end return frame end function device_new(plugin, device) local usages = device:usages() if usages[evdev.BTN_LEFT] and usages[evdev.BTN_RIGHT] then device:connect("evdev-frame", frame) end end libinput:connect("new-evdev-device", device_new) A few other example plugins are included in this patch Part-of: <https://gitlab.freedesktop.org/libinput/libinput/-/merge_requests/1192> 2025-04-22 10:25:55 +10:00			`plugins = [`

lua: implement support for disabling of features Because our lua hooks don't expose the device-added callback we need to cache any calls to disable a feature and then apply it quietly when the device is actually added. Any other call can go straight through. Part-of: <https://gitlab.freedesktop.org/libinput/libinput/-/merge_requests/1249> 2025-06-25 15:10:03 +10:00			`'10-disable-feature.lua',`
