Get current screen in custom module

[ModProg]

I want to display a “Sharing Screen!” message on the screen I am currently sharing.

I have set up the necessary code to display a message when I'm sharing any screen, but I'd like to be able to only show it for the screen the current instance of waybar is displayed on (compare “sway/workspaces” for a similar behavior).

Could we have a variable one can use in custom.exec and custom.exec-if that contains the monitor of the waybar?

Did you have a look at commit 0ea5143? This adds the output name in env var WAYBAR_OUTPUT_NAME when you use the exec command, at first glance at least in image and custom module.

It does not look like it's present for exec-if, although I have not tried that and could be mistaken. But you could check against it in your exec script, and perhaps just output nothing if it doesn't match?

@RobertMueller2 That env var doesn't seem to work, when I have a custom module exec a script to dump env > /tmp/envlog there are no WAYBAR_* env vars defined.

@jgarvin it does work for me with the config below.

Might be a bit hard to see, but the script just echos the WAYBAR_TEST_OUTPUT on each of the screens.

{
    "layer": "top", // Waybar at top layer
    "position": "top", // Waybar position (top|bottom|left|right)
    "height" : 50,
    "modules-center": ["custom/env"],

    "custom/env": {
      "format": "env:: {}",
      "format-alt": "env: {}",
      "exec": "/tmp/test-output.sh",
      "exec-on-event": false
    },
}

But I can't say if it's working with all possible configs. Would you mind sharing yours?

And which version you are using? This commit mentioned above is not included in 0.9.24 or earlier.

[jgarvin]

Ah I'm in 0.9.24, since new Ubuntu was released super recently I assumed it would be more up to date, my bad.

This looks very useful and works in exec. However, I notice that this variable is not set in on-click etc, it would help if it's also available there.

You can build from 7163752aa07f145e5951e2388b7693e19fc5d446 with this patch if you want on-click, on-scroll-x etc. to have WAYBAR_OUTPUT_NAME.

Thanks!
