Hello!
I am currently trying to spec out an algorithm that needs a hash algorithm (in this case I have to do things with the bits of the hash, so I can't rely on simple equivalence). It doesn't have to be a cryptographically secure hash, or even a particularly collision-free hash; I just need something that takes in an input, and returns back a consistent number with a consistent input (I'm happy translating the number myself to a binary sequence).
Now, I thought about writing a very simple operator to do it with a big if-else chain that simply loops-over a sequence and does a basic number-mapping, then adding the numbers and modding, but then I realized that that would *only* work with Sequences, which means strings wouldn't work.
I saw that there was a Stackoverflow post with someone implementing something in Java [0] , and that's what it comes to I'll to that (if someone would link me to how to add custom Java modules into a spec I would be grateful), but I was wondering if I'm overcomplicating this, and maybe there's something built-in now?
