[BUG] deflisten script not working about eww HOT 3 CLOSED

I'm not sure it will fix your issue, but you should try printing with print(line[-1], flush=True).
Doing this fixed some of my script, so it might works for you.

I'm not sure it will fix your issue, but you should try printing with print(line[-1], flush=True). Doing this fixed some of my script, so it might works for you.

thanks it worked! but one more thing:

in the line below, is it invalid to set the initial value of deflisten as the output of an command?
I ran eww state and it shows the literal command that I ran instead of the output of the value.

(deflisten active-ws 
    :initial `hyprctl activeworkspace -j | jq '.id'`
    `scripts/hypr.py -a`)

;; eww state
;; active-ws: hyprctl activeworkspace -j | jq '.id'

from eww.

That is indeed invalid! The idea of the initial value is to have some value that shows before any scripts push their first output, thus setting the initial value to some command would mean that eww would still have to wait for the command to finish before being able to proceed with rendering anything. To ensure that your variable is set to a correct value as fast as possible, I recommend just starting out your hypr.py script by running hyprctl activeworkspaces -j | jq .'id', such that eww gets a meaningful value as fast as possible.

And ye, that flush=True fix ensures that your script actually outputs the data, rather than just buffering it and then printing it in some batch at some point -- eww can't really do anything to avoid this being required :/ Thus, I'll close this issue. Feel free to re-open or create a new one if there are other issues.
