"triple state boolean", what's next, a double precision fp32?

• tuukkah 5y ago
  Also known as *bool, "Maybe Bool", "Boolean?", "Optional<Boolean>" etc.

    yeah, but if you really need to store 3 states, why not make 1 first-class concept instead of awkwardly combining two?
    • Spivak 5y ago
      Because a nullable bool has literally the same semantics as Maybe<Bool>. Why invent it again but in your app this time?

    Well, in browsers there's `HTMLMediaElement.canPlayType()` which returns one of the following strings: - "probably" - "maybe" - "" Reference: https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/canPlayType https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaEl...

      That's like my washing machine which has a Normal setting, a Standard setting, a Wash setting...

        Do you mean as in "If the washing machine has a Wash setting, what does it do if it is not set to Wash?"
        • isbvhodnvemrwvn 5y ago
          And what's the difference between normal and standard?

      My goodness. I remember having to explain this to my manager. They really wanted recording + playback in our platform. For as many browsers as possible. Even mobile (iOS, I'm looking daggers at you). In 2015. AFAIR I just said fuck it and made playback as permissive as possible (i.e., only prevent media playback if canPlayType returned ""). I don't know how advisable that is but the bug got off my back anyway. I dunno what makes this so difficult, why we can't get at least a definite "yes" even in 2021.

  Long Boolean! Yes, no, don’t know, weekdays only.

  If boolean comes from George Boole, then maybe we should call triple state values "Łukasiewiczan", it would make for a funny typing exercise :P https://en.wikipedia.org/wiki/Jan_%C5%81ukasiewicz https://en.wikipedia.org/wiki/Jan_%C5%81ukasiewicz
