hl.get_active_monitor() returns nil

[gkohri]

Hello,

In my hyprland.lua file, calling the function hl.get_active_monitor() returns nil when hyprland starts causing some key bindings to fail.

Once Hyprland is running, I can open a terminal and call hyprctl reload. Now the function hl.get_active_monitor() returns a non-nil value and all key binds are correct.

I'm guessing there is some kind of race condition in that hl.get_active_monitor() gets called before the variable is set. At what point in the hyprland.lua file is it okay issue a call to hl.get_active_monitor() ?

Thanks.

can you show the config or do you expect me to read minds?

The relevant lines are simple:

local monitor = hl.get_active_monitor()
local width3 = monitor.width * 0.66
local height = monitor.height * 1.0

hl.bind( mainMod .. " +   "3",     hl.dsp.window.resize({ x = width3, y = height, relative = false}))

Throwing out the complete lua file is pointless because all the other lines work -- there are no other error messages or warnings.

After hyprland starts, I can restart it using hyprctl and the error message goes away. So, I'm guessing this is not the recommend way to set up this type of key binding. If you know how to do it differently, let me know.

this doesn't work because it's literally wrong. hl.get_active_monitor() runs once, when the config is loaded - it's never rechecked. It's normal at launch it's nil because hyprland is barely starting.

I think you want to throw in a function instead of hl.dsp.window.resize and inside it do all of those and end with hl.dispatch() for that resize

Thank you for your explanation. It now works.
