    I was curious how the times were obtained. It uses https://github.com/nathan-osman/go-sunrise , which links to this calculation method: https://en.wikipedia.org/wiki/Sunrise_equation#Complete_calc...

    Of course, you can get this information in Emacs, too. You'll need to get your lat and long, first:

        (setq calendar-latitude  12.3456
              calendar-longitude -98.7654)
    
    Then, you can `M-x sunrise-sunset` and see the times (and total daylight hours) in the echo area.

    Great looking app!!

    I immediately checked how you do location lookups:

    > IP lookup is powered by https://ipinfo.io. They provide a good service so please don't spam requests.

    There was a thread about them recently — the scale of their operation was very surprising.

      Thank you very much! I appreciate talking with you in the other thread! I told the repo owner not to worry about "spamming" our service. We are happy to support as many requests as people can throw at us.

      Internally, when it comes to API requests, we are doing our best to reach an "unlimited" level of API requests. On the operational side, we are just getting started. The distributed network of a thousand servers we operate only runs a handful of diagnostic tests (ping, traceroute, etc.).

      We have a lot of plans, and I hope you will find us providing more fun stuff as we continue to grow!

      It _is_ possible to use native OS APIs for location lookup, but these all seem to rely on cgo. Which was a bit intimidating for a "let's learn Golang" project

      (Probably not the nicest code and no doubt I've broken a lot of Go idioms, but it was a good learning exercise)

      IPInfo is a good service and their developer relations were surprisingly relaxed about me (mis)using their API this way

      • reincoder 11 days ago
        "Surprisingly relaxed," you say. Let me tell you about the time our users reverse-engineered our apps, submitted 2.2 million IPs, and broke our systems for our hackathon.

        https://ipinfo.io/blog/ipinfos-ip-hunt-2-2-million-ips-submi...

        This is just our user base, to be honest and we like them for their mindset. We are happy to see users try our service in different ways and we learn a ton from them in that process. I certainly learned from you :)

    Windows build works fine (Windows 10 Professional x64 22H2).

      Thanks! (Don't have a Windows machine right now so that's very helpful)

    I live in a place where it often rains, and I really love sunny weather. It makes me feel a bit down when I see that it's already dark by the time I get off work. I was wondering, since the Earth's revolution is taken into account, the time you get should be different every day, right?
  • voidUpdate 12 days ago
    Does this pull the times from an online service or are they calculated locally? I tried to read the code to work it out but I don't program in Go so I got a little lost
    • jbreckmckye 12 days ago
      It gets your latitude/longitude from an IP lookup service, then does a geometric calculation locally
      • jmholla 12 days ago
        Is there a configuration file or command line option to provide location information manually?
        • jbreckmckye 12 days ago
          Yes, you can use `--loc="12.34,56.78"` where the values are longitude and latitude.

          You can also override the Timezone with `--timezone` (passing an IANA timezone e.g. America/New_York).

    Cool! Can we use the sky hue as Terminal background or overal “theme”?
  • kseistrup 12 days ago
    This is nice, I like it!

    Is there a way to make it use 24h time, rather than AM/PM?

    • kseistrup 12 days ago
      If I use e.g. `daylight --timezone=Europe/Copenhagen` it does actually show the 24h times, which is nice. But til still appends AM/PM, which is kind of weird. :)

    Is the noon color scheme supposed to look like Finn from Adventure Time?
