    >Virtually all the languages we humans use—spoken, written, or artificial (such as programming languages)—are fundamentally one-dimensional.

    Anyone having a look at a musical score can conclude this is wrong.

    Even when it comes to spoken language, intonation is conveying a lot, even in languages which are not classified as tonal.

    All that said, that's nice to see an exploration of exotic expression form. It doesn't need to down other approach to make shine its own.

      It's all about semantics and representation. All data is (can be represented as) one dimensional. Musical scores are definitely on the one dimensional side of the spectrum however (e.g., see Lilypond).

      • gmueckl an hour ago

        Music notation is definitely not one-dimensional because it encodes simultaneous occurrence and simultaneous time-progression of independent pitches (e.g. a sequence of cords played legato).

        • Ferret7446 15 minutes ago

          And text encodes multiple bits per character. That's a meaningless distinction (or it means as much as you want it to mean in a subjective semantic debate)

      > musical score

      sheet music isn't a language, it's a notation. it's just a concise way to represent a waveform (a song). and it's certainly one dimensional because you either play the song forwards or backwards.

        >sheet music isn't a language

        of course not a language in the same way English or Spanish are languages, but certainly a language in the same way mathematical formula, Lisp, or Java are languages.

        >certainly one dimensional

        The X axis represent time and the Y axis represent pitch. Moreover, you can have multiple pitches at the same time. I'm not a musician nor a geometrician but it does seems 2D to me, in a way regular text is not.

    I love this concept but I feel it is hamstrung by the need to write it using a text editor. If the rectangles were defined by actual graphical shapes it would be a lot easier to read and understand.

    Also I wonder if positional parameters would need to be replaced by named arguments.

    I consider Unreal Blueprints to be essentially a 2D language with the data flow and the execution flow modelled in separate dimensions.

    • dkersten 4 hours ago

      Max/MSP actually kinda encodes this into the language too: when all else is equal (eg if you connect the same data output to the input of two print nodes), nodes on the left happen before nodes on the right (normal input/output connections go from top to bottom in Max, unlike Blueprints and most others where its left to right).

  • xigoi 8 hours ago

    Having only the corners marked out with weird markers makes it hard to visualize the rectangles. It would be nicer to have the entire rectangle laid out of Unicode box drawing characters.

    I'm guessing the author doesn't speak Spanish. :)

      At least here in Argentina you can say "recto" with a straigh face everywhere. And it means straigh or perpendicular.

      The other meaning of "recto" is used only in medical literature or in mean jokes where you pretend to talk seriously.

      I worked with teachers of other countries of Latam, sometimes in geometry problems for children. For example, it's usual "ángulo recto". I don't have it in my list of taboo or problematic words.

      For example a kite-like cuadrilateral has a different names in each country, none in offensive, but you must be very cautios to ensure everyone understand the same meaning.

      Also, ur kids dont understand am/pm that is usual in other countries. To avoid problems everything must be between 1:01 and 11:59.

      Seems from japan. I often see names from japan to be Spanish words that often are not the best. e.g. verso (can be a poetry verse, but also in some countries a cheap lie), pajero (a car that can drive over hay, but in some countries wanker)

      I thought the name was intentional. :)

      The other geometrical meaning :)

      My thoughts exactly lol

  • rickcarlino 10 hours ago

    Has this paradigm been explored as a basis for visual programming languages? It seems like it could do a better job of handling the “density” of a program, which is often a problem in VPLs.

    There is a whole category of multiple dimension languages on esolang [1]... Nothing you'd really want to use other than to impress someone.

    No languages captures time as a dimension, yet.

      I think emiT [1] comes quite close!

      A time paradox from [2]:

        create x = 10;
        time point;
        print x; //prints 10 in first timeline, and 20 in the next
      
        create traveler = 20;
        traveler warps point{
            x = traveler;
            traveler kills traveler;
        };

      It's worth mentioning Orca[0] by Hundredrabbits, a 2-dimensional esolang which does incorporate time (and thus distance) and so is really 3-dimensional.

      It's also worth checking out Extempore[1] by Andrew Sorensen and Ben Swift, which grants you have incredibly precise timing semantics at the sample level.

      "Each extempore process has a scheduling engine built-in, allowing tasks to be scheduled for execution at a precise time in the future. Unlike threading constructs such as sleep() or wait(), which don’t provide strong guarantees about temporal accuracy (i.e. the time they’ll sleep/wait for), Extempore's scheduling engine is guaranteed to execute its tasks at the requested time (the number of audio samples since Extempore was started). This temporal guarantee is significant for time critical domains such as audio and graphic, and real-time systems programming."

      What's cool about this is that you're able to modify the program while it's running, and only update sections of it at a time, using the editor as a scratchpad, and it supports networking so you can precisely synchronize a herd of non-local devices and do things you'd have an extremely hard time doing in other languages. The applications extend far beyond just audio and visual programming.

      What both of these languages have in common is that they are designed for live coding, or as Sorensen says, cyberphysical programming. I am very interested in the marriage of these technologies and recent transformer models.

      > No languages captures time as a dimension, yet.

      Maybe not exactly, but there was one task[1] in ICFPc 2024[2] where you create programs that are laid out in 2D, and there is a special operator that causes the control flow to travel back in time. It was super fun.

      Besides Orca, Befunge, etc.. the McCulloch-Pitts Neuron is a graphical language with a discrete timestep, it solves some of the shortcomings of Orca and Recto where the evaluation has to do a lot of walking to traverse space.

      https://www.i-programmer.info/babbages-bag/325-mcculloch-pit...

      It does so by creating instant connection between events across large distances.

      Its inerrant parallalelism makes it also possible to do pretty complex evaluation on large canvases.

    Hexagony is another 2d language: https://esolangs.org/wiki/Hexagony

    Isn't this just braces/parens with extra steps?

    • fnordlord 9 hours ago

      I started to think the same thing when it got down to the for-loop example. Is Python 2-d because it uses indentation for blocks?

    Does Recto support something like this:

      I started thinking about Ven diagrams too and how that might be a useful flow control mechanism. It feels like there is a disconnect somewhere, and im not sure what it is.

    I think this is only makes sense if you have new hardware visuals like either VR or AR. It doesn’t make sense on a pancake screen

  • hamstor 9 hours ago

    Why the tight limit of only 2 dimensions? Seems unnecessary. A more general approach would be to support an arbitrary amount of dimensions

    • Mithriil 7 hours ago

      Three cheers for the language that naturally requires a VR headset to visualize 5D tensor logic.

    • mlajtos 8 hours ago

      Yes, we should store text in string tensors.

    "Straight" in Spanish. Perfect name for 2D and vectors.

    Truly interesting read! @mhagiwara The article reads very well.

    With the bandwidth left from parsing all that new information, all I can say is this is something. I know there's still a whole lot of figuring out to do.

    (I imagine if there were peeps from other-than-earth, they'd probably communicate in a manner as this - depicted in the "Arrival" movie)

    Thanks for sharing. I'll be donating a star on github and keeping watch-O
