Is there any way to show a notification when Caps Lock is pressed?

[siamhie]

Fluxbox would need to be completely rebuilt from scratch

Did you get a working line using that key_caps_lock?

In addtion to the xfce-builtin Caps-Lock indicator on the panel as mentioned in #12,
one could also bind a "send notification" action to the Caps_Lock key itself:
E.g. To bind the send-notification event in Xfce on command line with this one-liner:

Code: Select all

xfconf-query -c xfce4-keyboard-shortcuts -p /commands/custom/Caps_Lock -n -t string -s 'sh -c '\''sleep 0.2; notify-send -t 5000  -i caps-lock "Caps Lock" $(xset -q | grep -oP "Caps Lock:\s*\K(off|on)")'\'''

or alternatively within Keyboard-Settings add new applications shortcut,
with the command:

Code: Select all

sh -c 'sleep 0.2; notify-send -t 5000  -i caps-lock "Caps Lock" $(xset -q | grep -oP "Caps Lock:\s*\K(off|on)")'

and press Caps_Lock for the key to bind.
This gives a nice notification on the desktop when the Caps Lock key is pressed:
Caps Lock on
caps-on-notification.jpg
Caps Lock off
caps-off-notification.jpg

This surely is way more sophisticated code than my feable attempt to script a notification message every time the CapsLock key (and similar script for NumLock key) is pressed - when running Fluxbox...
My script does show individual icons for 'on' and 'off' state :

caps_lock.sh

Code: Select all

#!/bin/bash

value=$(xset q | grep "Caps Lock:" | awk '{print $4}' | grep -c on)

if [ "$value" -eq "1" ]; 
then
   notify-send -t 2500 -i  "capslock-on" "Caps Lock is ON" &
else
   notify-send -t 2500 -i  "capslock-off" "Caps Lock is OFF"
fi

num_lock.sh

Code: Select all

#!/bin/bash

value=$(xset q | grep "Num Lock:" | awk '{print $8}' | grep -c on)

if [ "$value" -eq "1" ]; 
then
   notify-send -t 2500 -i  "numlock-on" "Num Lock is ON" &
else
   notify-send -t 2500 -i  "numlock-off" "Num Lock is OFF"
fi

keybindings in ~/fluxbox/keys:

Code: Select all

Caps_Lock	:Exec sleep 0.3 && caps_lock.sh
Num_Lock	:Exec sleep 0.3 && num_lock.sh

[oops]

... Or a simple script into the terminal (in "real time")

Code: Select all

#!/bin/bash
for (( ; ; ))
do
echo -n $(xset -q | grep Caps)
echo " … (Crtl + c to quit)"
sleep 0.5
clear
done

Hello MXRobo the wayland script shows notification of Caps Lock On.

[MXRobo]

@i_ri Great, personally, I'd change the textual notification output, and I do NOT know this stuff, I'm just throwing what seems reasonably relevant at the fan.
I didn't try it because I can not even write a script or know where to keep it!

And fehlix's second one, keybind is the idea and what I tried last night, horrible attempt - and it should have responded, "cannot complete childlike command".

I have a caps lock light in the keyboard so I don't really need it, but I still like fehlix's very much, only if I had my druthers, I'd like it better if the notification for on was larger than the notification for being off – or only notified for on.
Hey Jerk! Caps ON!

This would be nice for the insert key too.

Nice, and nice toy!

Did you get a working line using that key_caps_lock?" Yes. It prints On or prints Off.

[Jerry3904]

Thanks.

I'm trying to have it show only when caps lock is on. Thought this would work but it doesn't, so would be interested in and grateful for any suggestions

Code: Select all

${alignc}${if_match "${key_caps_lock} == 1"}${color5} Caps Lock: ${key_caps_lock} ${endif}

[fehlix]

:

Code: Select all

${alignc}${if_match "${key_caps_lock}" == "On"}${color5} Caps Lock: ${key_caps_lock} ${endif}

Perfect, thanks. I had been using "On" and only switched to "1" in trying to fix it; but I never had the extra quote marks.
