How to use wlsunset/light.sh?

Issues & Assistance Sway
1

I want to edit the light.sh script in ~/.config/sway/scripts. i want to add my cordinates so it will be 4000k at night. i’m not sure what they are currently, but it’s brighter than 4000k. i assume that is because it’s not using my coordinates?

i have searched online, read through arch wiki, looked at google and github. i also read the page you posted below, before and after it was posted. i don’t see it mentioned anywhere how to use wlsunset besides manually, which i can do but want to do it automatically. i think that is why y’all used a script, and why i want to edit it. although i am not sure if that is the best way to go about it.

i see 4xx client error but i’m not sure what i need to do to not have 4xx client error. should i try and understand how to script first? and i tried to provide the 412 preconditions. i can add more or do more if it is needed, i’m not sure what i should do next though.

i’m sorry i broke the rules.

I’m not sure what you mean by 4000k, but there is no need to add your coordinates to the script because the whole point of the script is to determine your latitude and longitude for you, based on the output of curl -s http://ip-api.com/json.

#!/bin/sh
CONTENT=$(curl -s http://ip-api.com/json/)
longitude=$(echo $CONTENT | jq .lon)
latitude=$(echo $CONTENT | jq .lat)
wlsunset -l $latitude -L $longitude

I tested this script just now and it definitely works.

If you want to manually enter your latitude and longitude instead of using the script, then you should edit the line in ~/.config/sway/config.d/autostart_applications that calls the script, to instead use your custom wlsunset command. Putting it in ~/.config/sway/config.d/autostart_applications is what gets it running automatically.

Change this line:

exec ~/.config/sway/scripts/light.sh

To something like this:

exec wlsunset -l 39.9 -L 116.3

Substitute 39.9 for your latitude, and 116.3 for your longitude.

You can see other supported options with wlsunset -h:

❯ wlsunset -h
usage: wlsunset [options]
  -h             show this help message
  -v             show the version number
  -o <output>    name of output (display) to use,
                 by default all outputs are used
                 can be specified multiple times
  -t <temp>      set low temperature (default: 4000)
  -T <temp>      set high temperature (default: 6500)
  -l <lat>       set latitude (e.g. 39.9)
  -L <long>      set longitude (e.g. 116.3)
  -S <sunrise>   set manual sunrise (e.g. 06:30)
  -s <sunset>    set manual sunset (e.g. 18:30)
  -d <duration>  set manual duration in seconds (e.g. 1800)
  -g <gamma>     set gamma (default: 1.0)

i’m not sure what the issue was, i don’t think it was working for me. my screen wouldn’t turn orange. i think i checked and even killed wlsunset and light.sh. to check and see, it was the same.

thanks anyway! yes i ended up finding a similar solution. i’m not sure if this is proper, i was confused because i thought wlsunset would have a config like redshift. i don’t think that is the case though. i’ve just never run accross that type of program before.

but, i just ended up adding

exec ‘wlsunset -l x -L y’ to /home/user/.config/sway/config

from this reference/autostart.

https://wiki.archlinux.org/title/I3

i’m now using an orange screen and am happy.

thanks.

Experiencing quite the same anomalies with two monitor set. It is randomly choose monitors to apply light settings. Sometime one, sometime another and sometime both of them. So I gave up and just make shortcut for the ‘idle_inhibitor’ in waybar. When I make right-clicking and it re-initiate(restarts) light script. Like this below:

        "idle_inhibitor": {
            "format": "{icon}",
            "format-icons": {
                "activated": "",
                "deactivated": ""
            },
            "on-click-right": "~/.config/sway/scripts/light.sh"
        },
