The Nineteenth Byte

@HyperNeutrino Yes, thanks!

user165474

No problem :)

user165474

If I may ask, what's it for?

A joke language

Based on making a huffman tree from golfed Python

user165474

12:07 AM

Hm. I'll need to ~~read the wikipedia article~~ do some research on what that is :P

based on my current data, for example, a space takes only 4 bits

user165474

Ah okay.

Had thought earlier about programming languages with variable bit (not multiple of 8) tokens, but this is the easy first try

Currently, it's based on characters, but if I can include common names (plus whitespace), it would probably compress even better

user165474

Interesting. Is it going to be a simple language or one of those crazy TC-complete but insane languages?

It's a cheaty joke language, where you actually write Python, then run it through a converter, and the output is your "code" that runs in an interpreter (which just converts it back into Python code and runs the result)

user165474

12:15 AM

Hm. Interesting.

But in theory, you could learn its huffman tree by heart and write the code in a hex editor, so it counts as a language

(If you're looking for crazy TC-complete but insane languages, I have other languages )

((Although Aceto is surprisingly easy to write))

user165474

Aceto looks interesting. Almost reminds me of Klein.

user165474

OIL looks tricky though.

It is.. I spent hours on implementing fixed-point decimal division

You must make a regex that matches everything except itself, including delimiters. For example, /PPCG/ must not match /PPCG/, but must match everything else, like something, and PPCG. If your language allows compiling regexes from strings, you can argue that the quotes are your delimiters, and u...

@Mayube I like the multi functions, they were an idea I got from Clojure

And also, you know C++'s access modifier things in classes right

They'll work really well with Aether

@Qwerp-Derp Just out of interest, can one of the functions in a multi function use one of its namesakes in its own definition?

10:24 AM

@trichoplax So in a multi foo with two separate "mini-functions", you're asking if I can reference one with the other, right?

If so, then yes

Yes, so that the example multi function could be written as the one that takes 3 arguments, then the other two versions as calls to that

Hmmm, yeah

@Qwerp-Derp -1 needs more braces

@Okx Eww braces, whitespace-based languages ftw

ew relying on whitespace

10:26 AM

Can a multi with two mini-functions have both of them refer to the other (mutual recursion) if there is a suitable exit condition?

-1 using clojure principles but python block syntax

If you want a language to be popular in TNB it had better have no braces or whitespace :P

@trichoplax Hmmm, I think so

so @Qwerp-Derp a multi function is aether's awkward version of function overloads?

@Mayube How are they awkward?

10:28 AM

just have implicit overloading, it's better IMO.

so like, if you define 2 functions with the same name, but different arguments, they'll be separate functions and the correct one will run depending on which arguments you pass

make it so you end a function with a zero width space and then everyone will be happy

It seems like the two are equivalent (can multi functions have more mini-functions added later or must they all be defined in one place?)

@programmer5000 For the clock one, it looks good but I'd double check the input and output are sufficiently flexible - only accepting letters rather than numbers seems a little restrictive without being relevant to the challenge.

golf the above function

I don't even know what a bijective function is
