A Brief Introduction to Esoteric Programming Languages

FAQ > Where's Malbolge? Malbolge is a very interesting esolang, with the goal of being "as hard as possible to write programs in." I left it out because I couldn't figure out how to cover it well. It makes a brief cameo at 0:59 (lower-left), and I say a bit about it at the companion site: hillelwayne.com/talks/esolangs/#diversity > Is Game of Life an esolang? GoL is a special case of a **cellular automata**, which has been the model for several esolangs (esolangs.org/wiki/Cellular_automaton). GoL is Turing complete, but it's not really a *language*. It's more of a language substrate. You can use GoL to create OCTA metapixels, and then wires, and then spaceship signals, and then logic gates, and then circuits... ...29 billion GoL cells later, you get Tetris. codegolf.stackexchange.com/questions/11880/build-a-working-game-of-tetris-in-conways-game-of-life > Is HolyC an esolang? Yeah probs > Is Minecraft Redstone an esolang? Yes! A lot of games have mechanisms you can use to build programs *inside* the game. Redstone is a good example, as are Factorio circuits and Baba is You blocks. There's no collective term for this category; I personally call them "game-emergent languages". The big challenge with studying them is that, well, you have to have the game! I've already given Factorio hundreds of hours of my life, I can't afford to download Minecraft, even if it's for "research". > You mispronounced "Piet". Piet Mondrian was a Dutch artist, so I'm using the Dutch pronunciation of Piet ("Peet"). > Where's the music from? Richard Whaling's instagram: instagram.com/p/BzVjW7LBv1K/. > Is that Ida Noyes?

I am the original author of the “J and GolfScript suck all the fun out of golfing” post. I am not proud of it because I have since enjoyed golfing for reasons other than competing on character count. The posting was entirely borne out of a competitive mindset. I have since posted several answers in which I golfed in languages that are woefully unsuitable for golfing (mostly Unreadable). I would prefer to erase the posting from ever having existed, but I accept that it has historical value now. Amazing summary of the whole esolangs and codegolfing thing. Great video. Love it.

[@hillelwayne3236]

I think, even if you're not proud of the post, it captures well what a *lot* of people were thinking at the time (and still are!) about golflangs. There's an alternate history where the CGCC collectively decided to ban them, and I think it could have happened. Ultimately the site went a different way. I imagine if it banned golfscript we'd have seen a "schism" in the golfing community, with different competing sites.

18:00-ish: Actually, one Unicode character is most likely not 1 byte. In UTF-8, non-ASCII characters take more space the higher the character’s code point is. Æ takes 2 bytes to store, making “ÆP” 3 bytes long. The file size is worse in UTF-16 (every character is 2 bytes, unless the char code is U+10000 or larger, which makes it 4 bytes) or UTF-32 (every character is 4 bytes).

[@hillelwayne3236]

Yup, that was the mistake I called out I made ~17:59. It's still two bytes, though, because it's not using unicode! From the companion: > I made two mistakes in the section on Jelly: > 1. In the talk I mistakenly said that it uses Unicode “to pack in more opcodes”. Most golfing challenges are scored on bytes, not characters, so a single two-byte Unicode character scores the same as two ASCII characters. Instead, Jelly uses a different encoding than ASCII pack in more useful characters. The byte 0000 0100 in ASCII is the End of Transmission signal, while in Jelly it’s ¥. Some golfing languages do use Unicode, but the main saving is in a better codepage. > 2. I said Æ was “is prime”, but it’s actually the prefix for 2-byte arithmetic functions. ÆP is “is prime”. So in the codepage they chose, Æ is still a single byte, and Dennis picked Æ because it was a good mnemonic for "arithmetic expressions".

[@0LoneTech]

Tongue in cheek pedantry: UTF-16 is not worse than UTF-8 if your characters are in the U+0800 to U+FFFF range (excluding U+D800 through U+DFFF). Those encode to three bytes in UTF-8 but two in UTF-16.

If it involves tons of CJK characters, though, UTF-16 could be more space efficient than UTF-8, as most CJK characters could be stored using 2 bytes with UTF-16, but takes 3 bytes with UTF-8. While UTF-32 makes completely no sense yet since IIRC only codepoints up to 10FFFF was assigned at the moment.

[@abdulmasaiev9024]

0 bytes? Pfah. It still needs an interpreter which is some bytes. I can do better. What you need is just memory registers, and in fact specifically for the "is this a prime" question just one memory register capable of storing 1 bit of information, and by that I mean a physical piece of hardware, and that's it, you're done. Let's see how it works: "Is 2 a prime number?" - the memory register stores either a value that corresponds to true or false. If it's true, then hey, neat, it answered okay. If it's not, no biggie, just give it some time. After a while some cosmic rays or quantum fluctuations or somesuch will hit the register and flip the bit, and then it'll be giving the correct answer. It works the same for non-primes, too, with the correct/incorrect being reversed. With the requirements for correctness and time being as lax as they are, this should actually be good enough. 0 bytes for the program AND 0 bytes for the interpreter AND 0 bytes for the compiler.

it even gives the right solution to p=np if you observe the answer at the right time!

[@elitebyte_]

@@cobaltno51 how

[@cobaltno51]

@@elitebyte_ lets say 1 in the memory register stands for p=np and 0 stands for p!=np. if one of those answers is true, the register will contain the right answer at some point in time, given that cosmic radiation will flip the register atleast once. if you happen to observe the register at the moment it contains the answer, you can observe it. of course causation and correlation differ in this case. seeing a truthy value in a random sequence may correlate with the answer 'true' to some question, but the question never caused said answer.

I think the code golfers complaining about golf-themed esolangs are just scared to acknowledge the obvious problem: if your challenges are too easily broken by comedic custom esolangs, then they are probably too simple.

Then the people who try to break the challenge with custom esolangs might accidentally build a superior programming language.

[@Miju001]

MetaGolfScript still easily wins the golfing challenge in both cases, so that's not the issue. On the other hand, I think the problem of code golfing itself is somewhat ill-posed; and that adding outputs to the evaluation metric like the video mentions could be a step towards the solution

[@Nerketur]

There's also the obvious issue (banned by the community) of creating a language specifically to solve a challenge in one byte. Like H, for example. Now, you have to use a language that existed before the challenge was created. If a newer version is made after the date of the challenge, by default it can't be used, but the older version still can.

I made an esolang called Metastack where the program is made from an infinite line of stacks, wherein 2 of those stacks are special. (the command stack and the input stack) As the program is executed, it destroys itself. To loop it must copy from another stack. To conditionally jump it must swap the command stack with another stack. Yes, really. It traces its origins to Befunge which uses a stack to store data short-term, and i thought "what if we only had stacks to work with?" Its interpreter is made with ComputerCraft: Tweaked's integration of Lua. I haven't found an esolang that used a paradigm like this. If this is the first stack paradigm language (just like 2D paradigms of befunge), i'll be so happy.

One thing I don't understand about the FALSE program: After the line where the input is checked, we now have two copies of the same boolean on the stack. This is because we need the second one for the "else" part essentially. However, when f is executed, we now have our input, and then a boolean on top of that on the stack. Usually, you would use the backslash to swap those around, so shouldn't that part look like this?: ~[\f;!.\]? And also, the comparison to 8 would compare the boolean to 8, and not the input. Am I missing something? Edit: I am right (I think)! The example on the website of the guy that invented the programming language is incorrect (again, no guarantees)! The correct code would be: { factorial program in false! } [$1=~[$1-f;!*]?]f: { fac() in false } "calculate the factorial of [1..8]: " ß^ß'0-$$0>~\8>|$ "result: " ~[\f;!.\]? ["illegal input!"]?" " See the backslashes? They are needed to push the boolean down so that we can actually compare the number 8 to the input. Another edit: it seems like the backslashes got lost when pasting the code around for the website, and that makes sense since backslashes are the escape character for control characters.

really interesting stuff. code is art

That song by Richard hit's different/ Is there someplace I can listen to the full version? I have found a album on band camp but sadly this song wasn't there

[@hillelwayne3236]

Full piece is here: instagram.com/p/BzVjW7LBv1K/

[@aaiieenn]

I knew you would mention Orca! It's a really fun language and honestly so inspiring in making music. So far Shakespeare is my favorite because it's so ridiculous

[@Uveryahi]

I just stumble on this video. Man that was quite a ride! Golfing seems interesting :p thank you!

[@rustkitty]

Is it really valid to call orca a programming language, as opposed to a musician tool similar to chiptune trackers and physical midi grid instruments like a Launchpad? Or perhaps those are programming languages to? What is a programming language? Sorry, got a bit philosophical there... Anyway, very interesting talk and a lot of good food for thought.

[@Slingming]

great video and I agree with the conclusion

[@virkony]

Multicoding also used in other languages. E.g. type is one of the aspect you usually get. In Mercury you have modes and insts. It's just such languages usually use similar way to encode/represent that information as main code. But colorForth uses formatting as part of language and it is still generic language. If you think about how we have all that syntax highlighting in editors/IDEs trying to be in sync with how source code interpreted, it because mind blowing that colorForth solves that problem in its root cause since highlighting is a part of language.

[@satorian7157]

Orca, nice! this is the kick in the pants I needed to actually go and start making stuff with it

[@sebbes333]

0:54 What is that "language"(?) in the top left corner?

[@p1geon45]

most important piece if knowlege i got from this video, is that there is are languages called "Brainfuck, but every + is replaced with the bee movie script"

[@TianyuQi]

15:50 wait a minute reverse polish notation?

[@pratiklondhe5167]

This was a really great video , I go interest in learning System Programming

[@runforitman]

yeah I agree i don't like golfscript or anything else like that I can make a zero byte script find all the primes because the compiler will generate a program that finds all primes whether you give it a file or not I think its like putting the golf tee in the hole and being impressed youre getting 0 strokes

[@runforitman]

oh lmao he then said something like it though more impressive

[@jitumali9663]

I am half time in the video and am enjoying it...

[@elson2270]

Such a informative video! Great job!

[@uninteressant2151]

Thank you for that great video!

[@ZSquaredPlusC]

This is a really interesting video! Will you make more videos?

[@mackexr]

great vid cant believe it has so little views

[@cedricvillani8502]

13:48 you can just not use a high level language, which is always more efficient as long as you know what your intention is. Like using bitwise logical operators a05>>b010, anyway ^ or ~ not etc..

[@CristiNeagu]

A bit of feedback: Please don't use white backgrounds for screen presentations. My retinas are on fire.

[@Tigrou7777]

I was hoping to see the example shown in the screenshot (for computing PI).

[@PBlague]

Why do you only have one video on your channel!? You make absolute gold content!

[@hillelwayne3236]

This was my first time making a video. I probably won't make another for a long time; it just took so much out of me to make. I'm much happier doing longform writing, which I put on www.hillelwayne.com. Warning: on the whole it's a lot more technical than this video. My main audience is software professionals, while this was for CS students.

[@PBlague]

@@hillelwayne3236 That's really interesting! You made an absolute masterpiece as your first video, Not many people can do that! Wish you a great day :)

[@marckiezeender]

14:10 you can remove the square brackets as well!

[@unflexian]

yeah 14:11 and replace !=0 with >0

[@antonliakhovitch8306]

What an intriguing talk! I did notice two minor errors: 1. You called the Brainfuck data pointer a "program counter". As far as I understand it, the program counter points to code, not data. 2. With unicode, one character != one byte. It sometimes does, but only when you're using the subset of characters that also exist in 7-byte ASCII.

[@gustavgnoettgen]

I thought about how short programs could be or how graphic programing could look like but... wow i didn't know this whole genre existed!

[@codywaller2840]

My favorite esolang has to be HolyC. Not necessarily due to anything particular except the background of it, an absolutely fascinating story. Is it functional? If you want to talk to talk to God or make pictures of elephants, then yeah, other wise, not really. I’m sure most people here have heard of it, but if somehow you have not heard of Terry A Davis and his coding, give him a look up. Great video!

[@fntthesmth423]

"The Psychology of Programming" sounds like the coolest fucking class

[@leonardofernandez6488]

This video is incredible. Thank you for it. But, what the heck happened at 20:26?

[@suvetar]

Thanks Hillel, a well balanced and informative article that could have gone many different ways, well done Sir! Might I pick your brain on another subject, being simply (LOL) so you see a cognate or conjugation between Eso's and DSL's? (Domain Specific Language)
