The Nineteenth Byte

@Sherlock9 Of course :P

@Sherlock9 if the input is 0, prints a 0, if the input is 1, prints 1s forever.

Anonymous

It would be a minor change if the truth machine outputs the input value once if it is falsey and infinitely if it is truthy

DerpfacePython

@MartinEnder Crap, I can't output 1's infinitely in Logicode.

Sherlock9

def chain_add(seq, final_length):
 for i in range(final_length-len(seq)):seq+=chr(48+(ord(seq[i])+ord(seq[i+1]))%32%10)
 return seq

DerpfacePython

Does it still count if the code runs infinitely?

Sherlock9

8:05 AM

This is from my VIC cipher encoder

Anonymous

In fact, many of the solutions to our truth machine challenge would work with any truthy/falsey value as input

Sherlock9

In the for loop, I add to seq, and eventually look behind at what I've added if len(original_seq) >= final_length. I can't do lookbehinds in list comprehensions. I think I could mess with reduce() to do this, but I'm not sure how

DerpfacePython

What do you guys think of my lang?

@Sherlock9 reduce(lambda seq,i: seq+chr(48+(ord(seq[i])+ord(seq[i+1]))%32%10), range(final_length-len(seq)), seq) should work, but I haven't tested it.

I personally would use ? and : for ternaries (shorthand for the conditions)

@Mego But this isn't one of those langs...

And besides, I have conditions already

You have conditions, but cond?true_branch:false_branch is intuitive thanks to the many other languages that use that syntax

But I need help

Can anyone do it for me?

Martin Ender

This is the closest thing Stack Cats has to a truth machine, which outputs 0 for 0 and enters an infinite loop for 1, but you can't have both an infinite loop and output in Stack Cats: stackcats.tryitonline.net/…

@Dennis Can you add my lang, Logicode, to TIO?

I think that did the trick

Martin Ender

he might need a link to the interpreter.

seshoumara

Some year ago I made up a brainfuck derivated language specifically to be used to write grafical (simple) programs, but have 0 knowledge of how to make a compiler or interpreter.

Would asking for one as an actual question, be too much for this site? I can give all my reputation as bounty (150 so far, I registered last week).

Sorta: github.com/DennisMitchell/tryitonline

I have four projects going on now: two prefix calculators, a REPL for esolangs, and a 4004 emulator. :3

seshoumara

The language is simple, only has the 8 chars from bf and maybe 3 more, one for sure to change between coding the logic and coding the GUI elements, so the 10 chars have double meaning based on what tape you are.

o.c is the butt of a joke about golfing interpreters for golfing languages. Phase is a silly person sometimes.

Anonymous

@DerpfacePython It's very simple, which is fine for a simple language. You might experience growing pains as you add features, though.

seshoumara

yes, all the details of the language were (I have to just remember them) specified to the teeth and the GUI elements are simple butons, labels, text boxes with simple proprieties like color, size, position.

zyabin101

8:32 AM

@Mego Guido van Rossum was not a fan of map, filter or reduce and it took quite some persuading from the Python community for him to keep just map and filter

@Sherlock9 GvR doesn't understand the glory of functional programming, then :P

If reduce got shoved into functools, map and filter probably should, too.

Sherlock9

List comprehensions can't assign to variables and they can't access elements created in the same comprehension. As far as I know, they can do map() and filter()'s jobs, but not reduce(). I want Oxide to fix that, if possible.

Martin Ender

@MitchSchwartz how flexible is anarchy with output formatting? e.g. it doesn't seem to care if there is a single linefeed at the end or not, but are there any other flexibilities in the output format?

DerpfacePython

@DJMcMayhem the input has multiple lines and you need to add the two numbers on every line (and print it on a separate line)

DerpfacePython

And it looks amazing.

TùxCräftîñg

@DerpfacePython obviously it is

Sherlock9

@Mego I found some links about GvR's thoughts on map, filter, reduce python-history.blogspot.co.id/2010/06/… python-history.blogspot.co.id/2009/04/…

@MartinEnder well drat. I thought I would win it, but I can barely tie third. :(

Mitch Schwartz

8:51 AM

@MartinEnder is that \xf6 ? it seems to contradict the documentation, "The following is a complete reference of all commands available in Hexagony." (?)

TùxCräftîñg

implicit/explicit arguments parsing rules are really wtf rin Ru

Martin Ender

@MitchSchwartz well yeah... I was a bit lazy in the interpreter so all unknown commands (which includes the letters) set the the current edge to their value

but apparently it only works within the ASCII range

(and of course it doesn't work for any of [ \r\n\t\f`] because those get stripped before everything else is parsed)

you could say it's undocumented implementation-specific behaviour (e.g. the C# interpreter that is part of the EsotericIDE will throw an error on any non-whitespace characters that aren't printable ASCII)

Mitch Schwartz

huh, that's interesting

Martin Ender

I'm currently trying to figure out how on earth you were able to print a linefeed without alphanumerics and binary characters...

DJMcMayhem

I'm so confused. There's no option to create an account

DerpfacePython

8:56 AM

I just realised how awesome Downgoat's userscript was

Mitch Schwartz

but yeah with output formatting, the judge tests your_output.rstrip == expected_output.rstrip , except for special challenges like Quine where there is no flexibility with whitespace

DerpfacePython

It looks bloody beautiful.

Martin Ender

ah, so any trailing whitespace is allowed. that's good to know.

feersum

Really? I was sure I've had problems before where it wouldn't accept because of trailing spaces.

Martin Ender

oh and trailing null bytes too, that seems even more useful

@MartinEnder you can look at the source code of the page, or something like what i do, which is submit code that outputs every input character followed by ! (trusty tester.bf, last modified jan 28, 2014)

Martin Ender

well turns out there was one in this case :)

Mitch Schwartz

absent or inconsistent trailing newlines can be annoying for ruby and some other languages

Martin Ender

9:17 AM

so, now that I've got 13, do you want to compare whether we have the same?

Mitch Schwartz

(for some reason, -l uses chop rather than chomp)

well, if you want. i'm sure you use the same way to get a newline as i do though :) the only difference would be the layout. actually, i have two slightly different 13 byte solutions

Martin Ender

sure, but since I still have 3 characters that don't do anything except control flow, maybe we might come up with a 12-byte solution by combining ours or something

   ? { ?
  / : + !
 ' / $ ; ~
  , . . .
   . . .

Mitch Schwartz

  ? _ }
 . ! + ;
? " % / ~
 , . . .
  . . .

alternate:

  ? _ }
 ; + % ,
? . " / ~
 ! . . .
  . . .

Martin Ender

haha, those are crazy :D

Mitch Schwartz

the second one feels a little cleaner in the sense that the " isn't passed over extra times (which just happens to be harmless)

i actually got the idea for the path from your sum input solution :)

Martin Ender

9:23 AM

I already forgot what the exact layout of that was, but I do remember I had a _ there as well

I also considered starting with |$ or >$ so that you don't need the ~, but I haven't found anything good yet.

@MitchSchwartz do you want to try beating my HW solution? :) I'm sure it must be possible to reuse some of the ; (e.g. if I just omit the @ where it is right now, I could fit the P0 in the second line, but then the @ needs to go where the 0 is right now, so the score would be the same in this particular case).

@MartinEnder I just tried to run the program with the Ruby interpreter and the I/O seems kind of messed up

Do you know what I mean?

Martin Ender

ummm, no?

zyabin101

Well, my demo has been borked. I present to you, The Textbox!

feersum

9:48 AM

OK, first of all, if I run the prime example

after I enter a number and press enter it just sits there

until I press a key

Then it prints the answer and exits.

Martin Ender

oh okay, I never run any of my interpreters with user input, I always pipe the input into the program

feersum

And when I run the actual A plus B program, none of the outputs are actually visible if I use console input.

Because they don't get written until I type something

And then the text I'm typing overwrites the output

Martin Ender

I don't know how Ruby buffers console input

zyabin101

Here: schas002.github.io/The-Textbox

feersum

So the overwriting thing is because it prints only <CR>

It's still bad how an extra key has to be pressed to read the input though.

Martin Ender

9:59 AM

I assume you're on windows? the reason it prints <CR> instead of <LF> for you is that I get the linefeeds from the input (and the first character after a number would then be <CR> on Windows)

as for having to press an extra key that might actually be a problem of the console

use a pipe? :P

feersum

Other programs can read a line after the user presses enter...

Martin Ender
