bar not launching
i downloaded it from AUR first, when i launch it :
sysbar 09:37

then tried to compile myself from source,but same issue here's the verbose output(MESA warnings are not related to sysbar, it's a intel thing):

Humm it seems like the weather file got corrupt? Try running rm ~/.cache/sysbar-weather.json

I see, I've also had some issues getting sysbar running on another system of mine.
I'll see if i can improve the stability a little.
If you can compile this with make debug then run it with LD_LIBRARY_PATH=./build gdb sysbar then post where it crashes i'd appreciate it.
Sorry for the inconvenience..
no worries, i am really happy to help! here's gdb output:
Debuginfod has been disabled.
To make this setting permanent, add 'set debuginfod enabled off' to .gdbinit.

and after some debugging, it turns out that the control_network = 0x0 (null), and You’re dereferencing it to access button_action, idk if that's the issue tho, since i tried to fix it but yet the crash is still
Yup that's exactly the bug that i'm getting on one of my machines.
I'll try implementing some fixes hopefully by the end of the day, Thank you for providing valuable debug information!
wait lol the fix actually worked but only when running with gdb

Interesting, What did you change? I just want to be sure just in case.
@saberr26 Sorry for the long delay, Could you try now? It "should" be fixed.
No idea why it says "Unknown module: xyz" for you though?
that didn't work :

it was quite simple i just Fixed thread safety by moving all GUI calls to the main thread using signal_idle() instead of calling them directly from the background network thread. but that caused a race condition sadly(worked only on gdb)
I see, I also forgot about that so good on you for reminding me to do that. I've been thinking of rewriting the entire network module from scratch again since it's a complete mess + I would like to expand on a few things. Would you rather me try to push out a quick fix for this or wait until the network module is rewritten?
I should also ask, Does sysbar work fine without the network module? Just that one module in particular is causing issues?
I think i found the issue, I'm able to reproduce your exact issue. Will roll out a few more stability fixes and we'll see from there.
sorry for late reply mate, I was tired last night so I slept earlier than usual, however, the fix doesn't seem to work, same issues as before, i am free today so i will try further debugging, but before that, it's working for you right? if yes, what's the icons theme are you using, because i think it maybe the issue, since the Segmentation fault always happens at Gtk::Button::set_icon_name , likely because it's being called outside the main thread?
ok i did some further debugging,it sounds like the Crash occurs in sidepanel::setup_header() because Gtk::Button::set_icon_name is called before the button is fully realized, which GTK4 cannot safely handle???? sorry but i almost never touched GUI dev before so i might be dumb in some things

Odd.. Well since i'm unable to properly reproduce this i highly appreciate your debugging efforts.
Just as a sanity check.. Do you mind running it like so: GSK_RENDERER=cairo sysbar?
And do you mind sending me your config? ~/.config/sys64/bar/config.conf
I can give this another round of bugfixes/cleanups but i highly doubt it would fix it..
my config is same as yours:

Ah no lol The config is outdated, I rolled out a breaking change a few days ago.
Modules are no longer in the [main] section, They got their own dedicated [modules] section
Update sysbar
cp /usr/share/sys64/bar/config.conf ~/.config/sys64/bar/config.conf
And because i goofed up yesterday and forgot to include this, Add a controls module before every module in the end part.
Your modules section should look something like this:
[modules]
start=clock,weather,tray
center=hyprland
end=controls,mpris,volume,network,bluetooth,notification
icon-size=16
(Icon size stuff will be deprecated soon too in favor of more specific user customization via CSS instead of the config)
still same issue:

Yeah no clue.. to be honest.. Try removing every module and add them one by one?
@saberr26 Got my friend to try my bar recently, He used to have issues too. Can you try now?
