DWL Module Pipe Error

[nephitejnf]

I have madcow's ipc v2 patch on DWL and I have the tags module in my waybar config. I keep getting a broken pipe error (error 32) when trying to run waybar in DWL. This results in it crashing. I can run waybar on DWL without the DWL module and it runs just fine and waybar runs fine in River. It seems like something is off with DWL and the IPC right now.

Curl does interupt in the middle of startup because of my weather module.

I have the same issue. Was there any change or is there a solution?

[tomaskallup]

My dwl ipc v2 works fine for latest waybar. You can refer to my dwl code, but I don't have enough time to make patches now.

Hey, seems like the repo is gone? I just ran into this problem and was hoping for a fix. Sadly there seems to be no way to get waybar with dwl running (with clickable tags).

[maxhbr]

@tomaskallup : I still had a local clone and pushed it to https://github.com/maxhbr/fork-of-DreamMaoMao-superdwl

But I was not able to extract a working IPC version out of it into my config.

[tomaskallup]

Thanks for the fork, I took a stab at extracting the IPC logic, but I don't see much difference compared to the original patch. If anything it seems to be missing some fullscreen & floating notifications.

I might try to debug whats happening on waybar side and see if I can atleast find out whats wrong, but I don't have C++ experience, so my hopes are low. Hopefully someone who has experience with C++ & Waybar can chime in sooner or later.
