[BUG] Config errors without changing anything

[loqzer]

Describe the bug

I updated my system yesterday and shutdown without issues.
I woke up today to a few config errors.
The error window above waybar says
Config error in file /home/XXX/.config/hypr/conf/keybindings/default.conf at line 120: Invalid expression type: supported +, -, *, /,

I didn't change anything in the default.conf. The line from the config:
bind = , XF86Tools, exec, $(cat ~/.config/ml4w/settings/terminal.sh) --class dotfiles-floating -e ~/.config/ml4w/apps/ML4W_Dotfiles_Settings-x86_64.AppImage # Open ML4W Dotfiles Settings app

journalctl after reloading hypr:

I already tried updating / reinstalling the ml4w dotfiles but the error persists.

It doesn't seem to like the $(cat) bit since the latest update.

That's an upstream issue: hyprwm/hyprlang#72

[mylinuxforwork]

That's an upstream issue: hyprwm/hyprlang#72

Thanks. Than it's not directly a dotfiles issues.

[linux-fertxo]

Now we have to wait, or make some sort of workaround. Sourcing a file with user preferences "hard-coded" had the trick meanwhile we find out how to convert $( ) to whatever hyprlang understands now 😜

EDIT: I'm afraid we'll have to overcome the limitiation with new solutions...

I am still on 0.48.1 with my system.

[mylinuxforwork]

Just installed Hyprland 0.49.0. Now issues. I think we can close it.
