@Zacharý: Nice work!

Zacharý

@BMO On ... what ...

BMO

Haskell could be introduced like this:

tio.run/##VZBPS8QwFMTvwQ8RXmFJNrTRLJ5ivejBo9CjylKa1A2mSWhS/…

The D-Python polyglot :)

Zacharý

D is complaining about \u2028 even though it says in the docs that it's a valid EOL character.

BMO

Ah damn, for the 2d langs (and probably FreeDOS) we'd need to use that int#line N "..." part

Not sure how to get that to work with Haskell atm..

Zacharý

@BMO That won't work with C++, because macros have to be on their own line :(

BMO

19:43

Aah :(

Zacharý

Do you know of any C++ compilers that aren't on TIO?

BMO

Nope, I don't even really know C++

Though, there seem to be quite a lot of them.

Not sure though if changing the implementation would count, since we're choosing a language for an answer and ppcg defines a language by its implementation :S

Is there no hack to get int to expand to // or int //, along the lines of #define int "//"?

Zacharý

D would break.

BMO

Guess that's not going to work since # is a pre-processor directive..

@Zacharý We could put it into the ifdef part.

Zacharý

We're trying to get 2D langs to work...

The int is causing them to go into an infinite loop

BMO

19:50

@Zacharý Which one?

long would work too

Zacharý

Also, not gonna work.

@BMO Every funge (except Unefunge-98)

BMO

@Zacharý Why?

I mean a sole int yeah, but using the int #line N "..." would get the to work

Zacharý

@BMO It just keeps looping that line forever, there's no _ | v > < ^ to redirect them

@BMO C++ breaks then

BMO

We could put sth. like "\"v" as string, I think

Zacharý

@BMO D breaks

BMO

19:53

@Zacharý Yep, that's why I would want to expand int to int // such that C++ doesn't break.

Ah "\"v" breaks D, didn't check that one..

Zacharý

@BMO But D doesn't have #define...

BMO

| should do the trick then.

@Zacharý But D wouldn't need it?

Zacharý

@BMO | isn't gonna work either... the problem D has is that something comes after the closing ", since backslashes aren't treated specially in FileSpecs (the thing after the number)

BMO

@Zacharý Lol yeah, not sure what I was thinking -.-

Zacharý

Even if you replace backslash with |, D still borks because a newline is needed after "

If shebangs didn't break C/C++ (or at least in the compilers on TIO), it would be relatively easy...

BMO

20:03

@Zacharý A shebang would cause trouble w/ Haskell though

Unless we could use #!/usr/bin/env stack, but that's probably not what you have in mind

Zacharý

@BMO What do you mean

BMO

The thing about shebangs

BMO

20:16

@Zacharý: Can you define new types in D?

Zacharý

@BMO Yes, but then if we use typedef Python'll break

BMO

These would be all __builtins__ in Python that include a v: ['EnvironmentError', 'OverflowError', 'ZeroDivisionError', 'divmod', 'eval', 'memoryview', 'reversed', 'vars']

Bummer, #define and typedef need to be before the used ident :(

But I guess finding a compiler that expands macros used before the #define part would be easier than one that doesn't break on the line-stuff..

So we could do sth. like this

dzaima

@BMO C++ has standards so a compiler that does that wouldn't be C++

BMO

Is the pre-processor part of the standard?

Zacharý

@BMO How does D not break there?!

BMO

20:29

But even if so, maybe someone does it nevertheless..

I have no idea.. I don't know D at all ^^

Zacharý

Woah, vars is an alias ...

BMO

Oh yeah.

But it's after its usage which is great, now this should only be possible in C/C++ too

You know, I really fear that we get this to work and then gloriously fail on FreeDOS -.-

Zacharý

Woah ... never knew D hoisted aliases

BMO

Me neither :P

Wanna add a language? I, again, have the problem of being the last person that added one and can't just now :(

Zacharý

I can't think of any languages TO add, Braille doesn't want to work because Emojis are in there...

BMO

20:45

Hm, just skim the esolangs wiki for a 2d one - that should be possible to add. Or doing some differentiation between different kinds of brain-fuck would be possible too I guess.

Zacharý

I'll look later, I need a break right now

BMO

Sure

Zacharý

21:20

Okay, I'm going to look at them now...

I have no clue.
