README.md

Suntime Fish

Print daylight hours remaining, cache sunrize time from wttr.in
Screenshot

Installation

Download, chmod +x suntime.fish and put it in your PATH

fish is required to run this script, but doesn't have to be your SHELL to do it.

You can set a cron job to periodically update sunrize and sunset times:

0 0 */21 * *  /path/to/suntime.fish update

If no LOC is set wttr.in will use geo-ip for location.
You can set this in the script file or like this:

LOC=Stavanger,Norway suntime.fish update

Can chain with other scripts to change themes at sundown:

suntime.fish e  &&  light_theme || dark_theme

v0.3 with even less bugs and more options

* now using dawn time for sunrise
+ add optional clock with -c
+ chain to other scripts with -e for error code

For my location, wttr.in only gets the sunset right. For ‘sunrise’, it uses ‘dawn’ (the moment when the center of the sun disk is 6% below the horizon) instead.

E.g., Copenhagen, Denmark, today: wttr.in says 07:35:01,15:39:02, but the real time are 08:20:27,15:39:52.

@kseistrup Correct. This is intended, for that's how I use it.

You can change it to curl wttr.in/$LOC\?format="%S,%s" if you like.
❤️

This was altered upon reflection, in v0.3:

* now using dawn time for sunrise

Ah, right… Thanks!

Yes, I like sunrise better than dawn in this context.

v0.4 ~60% faster, more flexible options

+ add combining of commands and formatting options with -a
* more emoji options
