How to customize the config notification

[c02y]

https://yalter.github.io/niri/Configuration%3A-Miscellaneous.html is saying Set the disable-failed flag to disable the "Failed to parse the config file" notification. For example, if you have a custom one.

So how to customize it? What I need is, when the config failed to be parsed, it will automatically show me the error message in notification or open a new terminal running niri validate to show me the error message.

How can I do that?

Afaik you need to watch the event-stream of "Config loaded with an error" and make it run whatever you need, terminal or notify-send.

Btw you gave me an idea to implement eventually in niri-settings: automatically run and show "validate" on wrong saves ;)

It seems I have to keep the parse-event-stream-output running in background using some kind of script.

Never mind, I made a binding when it happens:

Mod+Shift+V { spawn-sh "kitty sh -c 'niri validate; read'"; }

Do you know how to keep the config-error-notification displayed without going away, like Hyprland? Since niri shows the error notification like only 2 seconds, sometimes I even didn't notice it.

Sorry, no idea about that.

@c02y I was actually messing with the animation settings today, and saw that there was an animation group just for the config error. I don't know if you can do anything with that, since the duration-ms only changes the transition, but still something to mess around with. duration-ms does not seem to work with spring. wiki page

Yeah, I know this part, it only works for the animation. Thanks though.
