Is your feature request related to a problem? Please describe.

I want to display cover image of current song in bar

Describe the solution you'd like

Allow scripts in src

Describe alternatives you've considered

I would still like scripts to be allowed to be used in src, but cover in bar could also be added to the music widget.

Makes sense, don't think this will be too hard to do.

Doesn't work on latest commit

config:

music_img = rec {
        type = "custom";
        name = "music-img";
        class = name;
        bar = [
          {
            type = "image";
            src = ''file:///{{poll:5000:playerctl metadata mpris:artUrl | sed -E "s/file:\/\/\///"}}'';
          }
        ];
      };

doesn't matter what combination of /s I use, it just won't work

That's odd, looks like the script output isn't getting captured. Also those slashes are horrible 🙃

If you try just a label element with the same script, can you get the URL to display as text? Also, can you double check it's writing to stdout (idk why it wouldn't)?

WAIT! That explains it, since i'm not able to get the uptime script thing you have in the power thing to work either

Also those slashes are horrible upside_down_face

I agree, I was trying everything, this just happened to be the last thing I tried lmao

If you try just a label element with the same script, can you get the URL to display as text?

YEAH IT DOESN'T

Also, can you double check it's writing to stdout (idk why it wouldn't)?

stdout works, unless this isn't stdout?

Ig this can re-closed, and a diff issue could be used, since it seems that no script is running.

Works in my repl, idk why it aint working

Though I know ironbar also uses pipes and listens for updates over channels, its probably a ironbar issue.

Standard pipe will be stdout, so that rules that out.

I'm happy to keep it here since we've got the context here. Have updated the issue to reflect that.

Ironbar runs commands by spawning a sh -c '<your script here>'. ~~Could it be a nixos quirk causing some kind of env issue with that?~~ Clearly not based on the REPL, scrap that. Scripts definitely do work for me on Arch on latest commit though.

I've just pushed up a commit into master that adds some additional logging to the script module. Could you try running a minimal config (ie just custom module with a single label with a script in it) using IRONBAR_LOG=trace (or IRONBAR_FILE_LOG=trace) and send the log pls? (It'll probably be very long)

This is weird maybe when one command fails, it brings down all the other commands? But why would some commands fail, they are all valid?

Oh very interesting, I've no idea why that would happen, unless you're triggering some kind of hrottling (why would dbus or a unix socket do that?) or there's some wires getting crossed in Ironbar.

Are you able to share your full config file (preferably in the compiled JSON format rather than Nix) and I can try and replicate exactly what's happening?

So! I think I've found the bug and it's in the script input parser - because the playerctl command contains a colon, it's hitting that and only taking everything after as the command. I don't think that'll be too hard to fix.
