BTW, Swi Prolog code is fully compatible with YAP, except YAP is much faster. (the exception to this is anything graphical, which hardly matters anyway)

Unless swi got new features recently

What is YAP?

@Dennis Yet Another Prolog (best name evar)

dcc.fc.up.pt/~vsc/Yap

Btw Ceylon would be up already if I had electricity.

Heads-up: it is very slow.

JVM langs tend to be that way.

Kotlin is a 12.5 second Hello World.

SWI is the basically the slowest prolog, but it's used do to extensive library support for all the things that don't work on TIO. SWI and YAP both follow the Edinburg Prolog Standard, while Ciao follows the ISO prolog standard. Visual Prolog does it's own thing, which basically explains why I've been having more problems with Ciao than I expected.

Holy $h!t, that's slower than Kotlin. Still, thanks!

Told ya. ;)

BTW: feature-request, add a button to clear all the fields. The code persisting between language changes is neat for making polyglots, but really annoying when there are like 5 arguments, a header, some code, and a footer, and reloading the page still keeps the code there. I could open a new tab and close the old one, but it's just slow and a pain.

Wait, reloading doesn't keep the code their anymore.

Cool

@Dennis can you add ReRegex?

i'll add it to the list.

There should be a globally editable list of suggestions and feature requests somewhere. HackMD or something?

@Dennis oh nice, Whirl. I was just thinking yesterday that (to my knowledge) we don't have an interpreter challenge for a wheel-based language yet

@MartinEnder Hey, you might be instead in ReRegex (few messages up). It's like Retina, but with the difference being that it uses Java regex, and after all replacements are done the program goes back to the top and starts over until there are no more possible changes.

Does that sound like something already in Retina?

s/instead/intrested

@Dennis Thanks (and thanks?)!

@ГригорийПерельман yes, Retina has loops as well. to loop a single stage until convergence you can use the + option and to loop multiple stages or an entire program, you group the stages together and then again loop them with + or use the shorthand {...}.

@Dennis It looks like UTF-8 output for PowerShell is getting interpreted oddly. See chat.stackexchange.com/transcript/message/36266156#36266156 and codegolf.stackexchange.com/questions/113790/…

It tries UTF-8 first and falls back to ISO-8859-1 if there is an error. Not sure what would cause the error though...

@AdmBorkBork I'll look into it asap.

No need for "ASAP" lol

@Dennis As another point of comparison, calculating the characters seems to work fine
