Q: Tips for Golfing in Vyxal 3

The reason for this question is because I made a deadlineless bounty and I need a tips question to link in the bounty Vyxal 3 is the third major version of the Vyxal golfing language. As it is significantly different to Vyxal 2, the tips there don't apply. Therefore, what tips and tricks do you h...

Dannyu NDos

Is Vyxal 3 usable as a praclang?

Ginger

depends on how you define "praclang"

lyxal

depends on what you define "usable as"

if you mean for hosting something like a web server, no, because there's no web server functionality :p

Dannyu NDos

Dang.

lyxal

but if you mean for data processing that can be done with a data-in data-out method, then it could be :p

Dannyu NDos

02:23

I mean... Would Vyxal 3 become a serious competitor to major languages?

lyxal

it would be as much as a golfing language can be

Dannyu NDos

Poor APL; never meant to be a golflang, but is used as such.

lyxal

given it has no importing other files it's usability for large scale projects is limited

200 reputation for golfing in Vyxal 3 Note that this is separate and distinct from the other Vyxal deadlineless bounty. Hi so Vyxal 3 exists and it's brand new and doesn't have very many answers at all. I think that needs to change, because it's a very cool language and y'all'll like it. In fact,...

damn i just got a golfing suggestion on one of my desmos answers which i havent gotten in a long while, so thats cool

it was suggested a savings of 2 bytes and i took the answer and shave off another 2 bytes, so thats total -4 bytes :D

How strong is brainfuck with only two unbounded cell? []+->

ATaco

My money's on TC

lyxal

if you asked for 3 cells, the answer would be yes

l4m2

3 cell is TC

ATaco

…What if [] only checked if the smallest 8 bits were 0..?

l4m2

@ATaco Then nothing check if it's a real 0

so it behaves modulo 256

ATaco

03:51

...Right

Dannyu NDos

But the real question is... What if one 2-adic cell?

ATaco

I know 2 stacks are TC...

Dannyu NDos

I cannot guess what the instructions should be.

l4m2

The usual 2-counter machine use COPY and allow arbitrary (un)conditional jump

@RydwolfPrograms did you ever finish that rust golfing library you were working on?

ATaco

Rust Golf? Rolf?

ATaco

05:03

Turns out ARBLE's branch function is broken, so the shortest way I can do conditional execution right now is range(0,condition)&x|body which sure is a solution.

CMC A GCC command line, likely bunch of -D, to enable a 2-char Turing complete language

#define $ +
#define $$ 1
#define $$$ =
#define $$$$ ;

-Ds containing ^ plus the flags used in this answer

should make a TC lang with dollars and spaces

xjb make your processor physically jump

@TheEmptyStringPhotographer How does your definition make any sense in that context?

@l4m2 What is an “xjb”?

Nov 18 at 22:55, by l4m2

@TheEmptyStringPhotographer mean nonsense

Dannyu NDos

Has anyone ever golfed in compile-time C++?

Like, abusing SFINAE for decision-problem?

constexpr would be a blessing at least in this context so

Q: Shortest C code to display argv in-order

I recently tried to produce the shortest C code possible to display all its command line arguments (which are stored in argv). I ended with a relatively small piece of code, and I was wondering if there was some trick I'm not aware of. Here's my try (I compile with C17, but any standard before C2...

holy long nap :p

CMC create a permutation of the integers 1 to 20 with longest increasing subsequence 2

I mean the length of the subsequence is 2

lyxal

@AaroneousMiller things you've missed include TNB RO election, Code Golf moderator election, new SE site launching (programming language and design), SE doing a silly and causing a 2 month long moderator strike and winter bash is no more

My CMC might be solvable by hand if you have very clever hands :)
