@BMO On ... what ...

Haskell could be introduced like this:

tio.run/##VZBPS8QwFMTvwQ8RXmFJNrTRLJ5ivejBo9CjylKa1A2mSWhS/…

The D-Python polyglot :)

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

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..

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

Aah :(

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

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 "//"?

D would break.

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

@Zacharý We could put it into the ifdef part.

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

The int is causing them to go into an infinite loop

@Zacharý Which one?

long would work too

Also, not gonna work.

@BMO Every funge (except Unefunge-98)

@Zacharý Why?

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

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

@BMO C++ breaks then

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

@BMO D breaks

@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..

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

| should do the trick then.

@Zacharý But D wouldn't need it?

@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)

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

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...

@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

@BMO What do you mean

The thing about shebangs

@Zacharý: Can you define new types in D?

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

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

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

Is the pre-processor part of the standard?

@BMO How does D not break there?!

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

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

Woah, vars is an alias ...

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 -.-

Woah ... never knew D hoisted aliases

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 :(

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

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.

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

Sure

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

I have no clue.

If you rewrite the entire thing I'll probably be able to fit in FreeDOS again

if we start with in then the next 3 bytes don't matter

Do you have another language to add? I'm pretty sure fitting/rewriting python in there is impossible.

fission?

funciton?

prelude?

@NieDzejkob 86695809994858(^^++^+^++!)

Add it ;)

Hah, I didn't know funciton - seems fun!
