Convert qsv enum --hash output to base62?

[tmtmtmtm]

I'm finding the new qsv enum --hash to be really useful in lots of scenarios, but I'd really like to shrink the resulting values down a bit, and one obvious route is to convert them to base62.

I can do that by piping the output through perl -pe 's{\d+$}{…}, but that's fairly gnarly.

My suspicion is that qsv luau map would be a much better route here, but despite lots of peering at the existing examples, I'm afraid I still can't get my ahead around how to actually do that. Perhaps this could make a good Cookbook example?

Or is there a much simpler approach that I'm overlooking?

@tmtmtmtm , I found this luau library that is perfect for the job -

https://github.com/Reselim/Base64

I'll whip up an example and add it to the Cookbook.

I'm also thinking of adding base62 encode/decode operations to the apply command.

Hi @jqnatividad — Does that library also handle base62? It looks to me like it's only base64, which would be a lot more awkward in my case (from what I can see it uses + and / for the extra characters which would both cause problems, though I could obviously run the output through qsv apply replace for each of those)

For the cookbook, showing how to call out to a library like that would definitely still be super-useful, but if you're going to add something to apply maybe it would make sense to add a way to convert between any two bases?

Ooops... my bad - lazy googling c&p 😉

But there is this other snippet for luau that we can possibly use

For the apply command, I'm thinking this fits the bill

Also found this reference implementation, though its not a library (yet)

WDYT?

@tmtmtmtm , I just added the encode62/decode62 operations to apply. Let me know how it works for you.
