does anyone want to help me design a golfing language ?

ATaco

With our powers combined...

We can make THE ULTIMATE mid-tier golfing language.

Conor O'Brien

XD yesss

trichoplax

@programmer5000 You just made me try to close that

Conor O'Brien

so I'll do exactly the opposite >.>

ATaco

00:22

I'm keen to help out, I wanted to start on something new anyhow.

trichoplax

Do you mostly want it to be succinct or also esoteric in some way?

Phoenix

@ConorO'Brien What language are you implementing it in?

Conor O'Brien

@Phoenix probably ruby, but maybe JS or C++

Phoenix

@ATaco i'm kinda in the same position. I want to learn C++, but I can't think of anything to actually do.

Conor O'Brien

@trichoplax I want to make a bonafide golfing language, so maybe that answers your question

Phoenix

00:25

I know ruby

ATaco

e s o t e r i c

Phoenix

I can sorta C++

ATaco

You know Java, right?

Phoenix

Yes

ATaco

Apparently I know JS, but I'm still not sure when that happened.

Conor O'Brien

00:26

@trichoplax your welcome

trichoplax

@ConorO'Brien One that's fun to golf in against others using the same language, or one that beats all other golfing languages?

Phoenix

@ATaco When you decided to make the tacoscripts?

ATaco

I can't say I knew JS then.

Conor O'Brien

@trichoplax Well, in order for there to be others who golf in it, it does have to have some chance at beating other golfing languages. I don't necessarily want to make the best golfing language, just a good golfing language. (so as a starting rule: strictly ascii)

ATaco

Nah, screw Ascii, use Win-1252.

@ATaco D: whyyy

I can kinda JS. I pretend it's java and StackOverflow the rest.

Fear the three byte RProgN2 quine.

Also, My solution in RProgN2 was just to make a keyboard for it.

Phoenix

@ConorO'Brien Sure, I can help.

Downgoat

@ASCII-only ono that mean I have positive level but I am downgoat so should be -0.001 unless I am actually upgoat :O

Phoenix

None of that statement makes sense

@Downgoat but i am in upside down land

ATaco

If I haven't made it clear, I'm very proud of RProgN2's ability to quine.

Downgoat

@ASCII-only ohhhhh true

Conor O'Brien

@ATaco it's impressive indeed

@ATaco it's beginning to sound like you wrote it specifically for quining lol

What's the q function do..?

Downgoat

parses non-quoted strings

ATaco

@Downgoat Out of curiosity, is that payload capable?

@Downgoat I don't support the eating of myself.

trichoplax

@ConorO'Brien Does it show who submitted what?

ASCII-only

00:37

@Downgoat it is essential nutrient not food

Conor O'Brien

no, it's completely anonymous, I didn't want to require sign in

Downgoat

@ATaco yeah you can do like [q|c (I think) and it would output program split into chars

though if you have like an array it'll break

ATaco

Output: x[q|

Hmm.

Conor O'Brien

does anyone want to take a guess as to how many answers there are >.>

ASCII-only

35?

Phoenix

Conor O'Brien

well, the 21st response was 42, so that's interesting

@ATaco [q|;"x[q| might work

Conor O'Brien

Destructible Lemon

I have idea for another language

it's mostly list comprehensions, and maybe macros for control flow

John Dvorak

Haskell?

Destructible Lemon

um

idk

probably not

actually I might remove the macros

control flow is by appending things to a list

and an if or short circuting operators

what do I call my list comprehension lang?

rather than tuples I think it would be a good idea to change that to 'variable-length data structure'

wait this makes no sense

1 and 2 both belong to the 2nd power residue class modulo 7 if I'm doing my math correctly

Arnold Palmer

At what point does an improvement to someone's answer become its own answer and not a comment?

Step Hen

@ArnoldPalmer when it looks different imo

Arnold Palmer

01:50

Seems reasonable enough

HyperNeutrino

It's all relative and fairly subjective. If you're using the same or a very similar algorithm, it's usually a golf. Do you have a specific case?

Step Hen

if you rewrite IO and algorithm or golf 20% off or if it looks like a different answer it could be reanswered

if you're just using a trick of theirs just link their answer in yours

Arnold Palmer

My code I just posted for the Brainfuck challenge

Step Hen

@ArnoldPalmer that's definitely different

Arnold Palmer

I mentioned using the same mechanic as another Python post, but it's not really an exclusive trick

Sweet

HyperNeutrino

01:52

For one, you're not using regex, totallyhuman is. Besides that, I also think it's a very different answer. Nice work, +1 :)

Arnold Palmer

I never know man. I've only been here for a bit so I don't want to come off as a jerk for posting over someone's post

Thanks man

HyperNeutrino

No problem

Step Hen

@ArnoldPalmer if s<1 or u>5: -> if s<1or u>5: iirc

@ArnoldPalmer and I believe we allow using input() instead of raw_input() and assuming correctly formatted input (may be incorrect there though)

Arnold Palmer

The issue with the raw_input is it's supposed to act like a Brainfuck program, so it's single character input, so no quotes allowed

Step Hen

@ArnoldPalmer oh right, nvm then

totallyhuman

01:56

I think you might have to switch to sys though

Since raw input requires a newline after each character

Arnold Palmer

That's a good point

That bumps it up to 381 :/

Q: Explanation of OEIS:A000236 - Residue Classes

I mainly use Lua, so elseif

HyperNeutrino

you just realized ._.

I assumed it was an exact syntax, not the result of a different syntax.

HyperNeutrino

lol

@ASCII-only i don't understand ASTs lol. that's just what someone here said at one point in time

dzaima

speaking of which, any way to do this?

if (a) {
  action1();
} else if (b) {
  action2();
} else if (c) {
  action10;

and by a switch of a variable I want that to become

  action3();
} else if (f) {
  action4();
} else if (c) {
  action10;
} ... the same as in the previous example many more else ifs

@MDXF yea. You can setup webhooks to automatically merge or ask github nicely to setup a mirror
