Discussion: use array of chars instead string as a alphabet about hashids.rb HOT 5 CLOSED

I'm not sure that I see any benefit to this since you could just create the alphabet string from an array.

alphabet = ['a1', 'b2', 'c3', 'd4', 'e5', 'f6', 'g7', 'h8']
hashids = Hashids.new("this is my salt", 0, alphabet.join)
hash = hashids.encode(1) # => "g5"

I'd prefer not to change the behavior of this package too much, especially not the public API.

EDIT: Ah, now I understand what you meant, that you want to substitute 1 character for n-characters, but that would defeat the purpose of this package and algorithm (and break compatibility with all other hashids implementations)

Thanks for quick reply 💯

1. for example, I want to use sequence of chars like: ['a1', 'a2', 'b1', 'b2']. In current realization it will be like: 'a1a2b1b2' or just 'ab12'. In this case, we'll have something like aab2 instead a1b1
2. It should be optional (I forgot to add it, sorry)

I will not consider anything that would break compatibility with the http://hashids.org/ specification.

okay, I got your point. Thanks, I'll close the issue 💗

I would anticipate such a feature. There is a big problem when you generated public ids: how to remove or to skip bad words/phrases, including all the slang and the live nature of the language.

One of the best solutions, imo, which does not need curse words dictionaries/NLP analysis and which works well is to have a predefined safe alphabet like A0, B5 and so on so any combination is never a bad word.

Don't see why alphabet can not be an array of strings instead of array of characters?
