Q: Convert codepoint to UTF-1

UTF-1 is one of the methods to transform ISO/IEC 10646 and Unicode into a sequence of bytes. It was originally for ISO 10646. The UTF-1 encodes every character with variable length of byte sequence, just like UTF-8 does. It was designed to avoid control codes. But it was not designed to avoid dup...

code-golf unicode

lyxal

12:49

@NewPosts Makes me want to implement UTF-69 where each character is represented as a string of 1s joined on 0s

and the length of each run of 1s is the character code for each character

the 69 in UTF-69 is just to make it extra confusing

because you'd expect it to use like 69 bits, but instead, it's just a horrible version of unary.

and so everything becomes either byte value 255, some number where just a single bit is 0 or where it's just less than 8 1s

so something like Hello, World! in UTF-69 assuming UTF-8 display becomes

ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿýÿÿÿÿÿÿÿÿÿÿÿÿÿïÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿûÿÿÿýÿÿÿÿÿÿÿÿÿÿýÿÿÿÿÿÿÿÿÿÿÿÿÿýÿÿÿÿÿÿÿÿÿÿÿÿÿÿ¿ÿÿÿÿÿÿÿÿÿÿÿÿýÿÿÿÿÿÿÿÿÿÿÿÿïÿÿÿ

Theory: Every MC update where the minor version is a multiple of 9 is bad enough to cause a large number of people to stick with the old one

Mayube

@RedwolfPrograms I think that applies to the version number as a whole. the changes in 1.8 were so extreme that the modding community stayed in 1.7.10 for years. The community didn't make a serious attempt to move on until 1.12

and even then there's still a sizable group of people who never left 1.7.10

Redwolf Programs

15:51

Oh huh, never heard about that

1.9 caused a lot of controversy too, so I guess we can't have any nice factor-based rules

@hyper-neutrino 1.8 brought a lot of changes to how the game worked, which meant Minecraft Forge, the most-used modding API took a long time to update, and had a very different API to pre-1.8

oh, I see

i thought people like hated the content or smth and i was like "i don't remember it being that bad"

Mayube

We lost a lot of mods to that change. Lot of modders were so opposed to basically completely rewriting their mods for a new version that they just stopped modding

Any tips for golfing this?

Mayube

17:12

I'm sure having my arguments ordered as y,x,z is going to upset someone

pxeger

@Mayube [... for i in range(x-1,-1,-1)] can be [... for i in range(x)][::-1]

Mayube

:o

does [::-1] reverse the list?

pxeger

yes

Mayube

Every python golf inevitably just becomes a series of list operations

pxeger

I think by reordering the cases in [33,66,-c,-96] you should be able to shorten [(n>93)+(n>=c)+(n>222)]

Mayube

17:19

I think I see what you mean

pxeger

Also the last line can be f=lambda n:[p(*[[n-d,4,252],[n-16406,2,246],[n-256,1,161]][(n<16406)+(n<d)]),([160]*(n>159))+[n]][n<256] - replacing the ternary if with a list index/selection

Mayube

yeah if I reverse their order I can save a byte

@pxeger congrats, you just replaced the last non-list conditional with a list :P

pxeger

lol

Mayube

It's all lists, always has been

pxeger

if/else and and/or are basically never shorter; you only use them in golf if you need lazy evaluation (e.g. in recursive submissions)

Also, you can submit as an anoynmous function expression with separate assignments, so you don't need the f=

Mayube

17:22

if only I could golf for i in range

oh really?

I thought you could only do that if there was nothing outside the function

don't know why I thought that

pxeger

~~(even if you had to include everything inside the function, you could just assign the other things inside the default arguments of the lambda to make one horrible expression for the same byte count)~~ nope doesn't work because the other functions rely on being able to call each other, which they can't if they're not stored as global variables

Mayube

Don't need the parens around ([160]*(n>159)) either

I could probably find a way to skip the extra lambdas and do it all in one if this was 3.8 and I had :=

cos I'm really just using lambda calls for assignment

pxeger

@Mayube so why not switch to 3.8 then?

Mayube

calling t=lambda n:... with t(y//c**i%c) assigns y//c**i%c to n, so that I don't have to type y//c**i%c a bunch of times and lose bytes

pxeger

you couldn't do it (as easily) with p, though, because you call it with a different set of arguments

Mayube

17:28

yeah

pxeger

if you switch to def you might be able to inline it, but that'd probably be longer in other ways

Mayube

yeah I tried that 2 or 3 times during golfing it and it was always longer

@leo-but-not-the-other-guy Welcome to The Nineteenth Byte! In answer to your question earlier, I'd say: 1) Sure, we always welcome new golfing languages (though you may find that you're the only person who uses it); and 2) another idea is to golf in misp directly, without making a new language.

leo-but-not-the-other-guy

@DLosc Cool, i was worried because it looked unmaintaned, but maybe i can fork it and look at the code. (Im a python noob, so keeping the code working is the best i can do)

user

19:51

@Mayube I thought each distro used its own thing (on my computer, at least, I have an app called Ubuntu that launches an Ubuntu terminal that doesn't look anything like cmd)

Anush

CMQ can a regex tell if a string has an upper case, a lower case and a digit and no three characters in a row from the same of these three classes?

user

And I think if you use Windows Terminal, you'll have to make a profile for Ubuntu (or any other WSL thing) yourself, the defaults are just cmd, powershell, Azure (?), and something else

@Anush Probably, especially the more advanced flavors that aren't even regular expressions anymore

pxeger

@user They all use conhost.exe, which is a console host (like a terminal), which I think is what Mayube meant by cmd (but cmd.exe is actually a shell, like bash (but worse))

user

Ah

Anush

@user I would be interested to know if it can be done in a standard regex

user

19:54

(might want to put a disclaimer for that last parentheses: "DISCLAIMER: I am a Zsh fanboy") :P

pxeger

@user ok but have you ever tried to use Batch (the scripted form of what cmd is interactively)? Its only flow control is a really terrible kind of for loop, and... goto

look at Neil's Batch golf answers

user

The only thing I ever tried to do in Batch was print something, and even printing newlines was painful, so I don't disagree :P

I don't touch shells beyond the minimum necessary for doing other stuff :P

caird coinheringaahing

@Anush The fact that (I'm guessing) it doesn't matter what order the upper case/lower case/digit are in (e.g. both Ab1 and b1A would be matches, ignoring the "no three chars" bit) makes it a lot more complex for a regex

I'd suggest just doing some basic string manipulation / using multiple regexes

pxeger

@Anush I'm pretty sure they could, but it would be a very complex one

and like caird said, you definitely shouldn't lol

user

Well, this is Code Golf, so screw bad practice, imma try it

pxeger

Create a matching { at the very beginning of the program

pxeger

Current ideas include: create an implicit "define function" block

@user yeah, that's what I was thinking; basically the above, if { mean "define function"

DLosc

20:50

@user Note that whether this strategy is useful will depend on whether a program that starts with a {block} is a common construct in this language.

But yes, that's exactly what HBL does (with parentheses)

True. It looks like defining functions will probably be pretty common, fortunately

@Anush I think ^(?=.*[A-Z])(?=.*[a-z])(?=.*\d)(?!.*(?:[A-Z]{3}|[a-z]{3}|\d{3})).* should do it: Try it online!

with copious use of lookaheads, and assuming the string is printable ASCII only

But yeah, probably better not to use regex for this task.

Well, let's try it, actually:

CMC: Given a string of printable ASCII characters, return truthy/falsey (or two consistent values) based on whether the string contains an upper case, a lower case and a digit and has no three characters in a row from the same of these three classes.

World1 -> false (too many lowercase in a row)
WorLd -> false (doesn't contain a digit)
WorLd1 -> true

DLosc

@user 0_0

user

It's quite a naive solution, I just get all possible orders of the character classes' first appearance and generate a regex for each of them (generator program) :|

DLosc

Yeah, my first thought was to test for every possible order of upper-lower-digit, but then I was thinking about the negative lookahead for the no-three-in-a-row rule and realized lookaheads could be used for the must-have-at-least-one rules too.

I think $&_Na\&_X3NIaM[XUXLXD] should work in modern Pip (22 bytes), though I haven't tested it.

Slightly oversimplified explanation:
- Make a list containing the builtin regexes XU = `[A-Z]`, XL = `[a-z]`, and XD = `\d`
- For each regex:
> Count its occurrences in the input string
> Test whether the regex repeated three times occurs in the input string; return falsey if it does, truthy if it doesn't
- Logical AND all the results

@cairdcoinheringaahing Brachylog, 5 bytes: ^₂a₁?

@cairdcoinheringaahing yay Brachylog FTW

caird coinheringaahing

a is "affix" and a₁ means "affix from end" i.e. suffix, right?

Leaky Nun

yeah

caird coinheringaahing

Jelly needs a startswith/endswith command

Leaky Nun

22:49

that's too prolog-like

Fmbalbuena

please answer this

Unrelated String

@cairdcoinheringaahing you can use aƑ or something of the like as startswith so long as all of the elements you care about are truthy

i think

caird coinheringaahing

If you're trying to do right.startswith(left), you can do =Ạ I believe

Unrelated String

oh yeah that works too

and then endswith is not so easy because the vectorization semantics are no longer on your side

pretty much have to double reverse or explicitly tail

DLosc

@LeakyNun Oh, duh. Nice. ^_^

Unrelated String

i guess ⁼ÐƤẸ is also an option for left endswith right lmao

@cairdcoinheringaahing is it exactly this or absolutely nothing similar

caird coinheringaahing

Absolutely nothing similar

Unrelated String

oh boy

caird coinheringaahing

Try it online!

Unrelated String

ooh, nice mold

caird coinheringaahing

Yeah, I was happy about that one :P

I need to remember that as a way to truncate to length, especially if you know that len(A) > len(B)

Unrelated String

23:23

I... think this works for 6?

No idea what all of those leading zeroes are from

I guess the eval is causing the nilad interaction somehow

@DLosc Modern Pip, 8 bytes: SQaS#a=a

Bubbler

@DLosc How modern is Modern Pip?

caird coinheringaahing

@UnrelatedString Yeah, try replacing it with "to digits": Try it online!

DLosc

@Bubbler As in, more modern than the version on TIO. You can run it on the Replit interpreter.

Looks like the S operator was added September 12 of this year.
