Nothing happens when i tap with 1 finger or hold with 4 finger. I cant debug it since i dont see any log messages.

[HritwikSinghal]

if you can tell me where to look for log message for tap client, maybe i can debug it @iberianpig

[iberianpig]

I looked at the yaml and the following seems to be wrong

• The indentation of 1: below the tap is missing.
• Please use command: instead of sendkey: for debugging with echo.

tap: 
-1:
+  1:
-  sendkey: "echo ----------------tap1----------------------------"
+  command: "echo ----------------tap1----------------------------"

BTW, sendkey: PLAYPAUSE didn't work for spotify play/stop in my environment.

oh, my bad, but even after indentation, it does not work. and command does not output anything

i am using rhythmbox and lollypop and this used to work in my prev installs. so can you tell me how to debug it?

1. For checking fusuma-plugin-sendkey working correctly, you can emulate send key from the terminal like following

$ fusuma-sendkey PLAYPAUSE

2. fusuma-plugin-tap parses verbose log of libinput
   You can check tap events from outputs of $ libinput debug-events --enable-tap --verbose

$ libinput debug-events --enable-tap --verbose | grep --line-buffered tap:

event8  - tap: touch 0 (TOUCH_BEGIN), tap state TAP_STATE_IDLE → TAP_EVENT_TOUCH → TAP_STATE_TOUCH
event8  - tap: touch 1 (TOUCH_BEGIN), tap state TAP_STATE_TOUCH → TAP_EVENT_TOUCH → TAP_STATE_TOUCH_2
event8  - tap: touch 2 (TOUCH_BEGIN), tap state TAP_STATE_TOUCH_2 → TAP_EVENT_TOUCH → TAP_STATE_TOUCH_3
event8  - tap: touch 1 (TOUCH_END), tap state TAP_STATE_TOUCH_3 → TAP_EVENT_RELEASE → TAP_STATE_TOUCH_2_HOLD
event8  - tap: touch 0 (TOUCH_END), tap state TAP_STATE_TOUCH_2_HOLD → TAP_EVENT_RELEASE → TAP_STATE_HOLD
event8  - tap: touch 2 (TOUCH_END), tap state TAP_STATE_HOLD → TAP_EVENT_RELEASE → TAP_STATE_IDLE

And I noticed that libinput v1.17.0 debug-events format is changed, and it doesn't work tap and hold detection.

• v1.10.4 N/A (stops working after palm detection)
• v1.14.1 works
• v1.15.5 works
• v1.16.5 works
• v1.17.0 N/A (--verbose log format has been changed 😭 )

And I noticed that libinput v1.17.0 debug-events format is changed, and it doesn't work tap and hold detection.

* v1.10.4 N/A (stops working after palm detection)

* v1.14.1 works

* v1.15.5 works

* v1.16.5 works

* v1.17.0 N/A (--verbose log format has been changed sob )

Wait so what does this mean? no more tap events ?

[iberianpig]

No, the tap events are still being written out.

On the left is the log of libinput debug-events --verbose --enable-tap for v1.17.0 and on the right for v1.16.5.

Some logs colored on the left have changed format, it needs to be rewritten in the parser for v1.17.0.

This is a problem with fusuma-plugin-tap, which depends on the verbose log. For a permanent solution, I think we should get events from libinput API or evdev instead of verbose log.

i think if you use libinput API, it will also fix the issue where fusuma executes 4 finger tap after doing 3 finger swipe and holding.

[HritwikSinghal]

Hold gestures are coming to libinput by default so you may want to wait for them. See https://gitlab.freedesktop.org/libinput/libinput/-/merge_requests/602

[TonCherAmi]

It seems to have been merged.
