koto VS rune

Putting the finishing touches on a procedural macro to bind Rust code to koto we want to use in synth. Also a blog post about it is on the way.

I'm currently trying to improve the vtable dispatch in koto (because I want to use it in synth).

I've been working on Koto which is intended for this kind of use case. I've been thinking about extending Rust applications with scripting, and I have games in mind but more generally I'm interested in rapid iteration in creative applications. It's still very early so I haven't shared it more widely but I'd be curious to hear what you think.

Hm I never heard of Rune, and I have heard of all the others (although this article gave me more info about Val):

This part is interesting, as I've found many benefits from having a layer of indirection between the app-level data definitions, and the C/C++ struct level. I recall that Jai used to advertise the SoA -> AoS transforms but that was many years ago.

It provides many of its features by deeply integrating the "DataDraw" tool into the primitives and constructs of the language. DataDraw is a code-generation tool that generates highly-optimized C code which outperforms e.g., the C++ STL given a declarative description of data-structures and relationships between them. For more information, see the DataDraw 3.0 Manual.

I've never heard of DataDraw either .. I wonder who uses it?

I can field questions folks might have on DataDraw. I'm not Bill, but I wrote the docs PR that recently overhauled the Rune README to highlight a lot of this interesting info about its use of the DD tool.

Another neat thing about DD -- the Rune compiler/grammar itself are written as DataDraw types, and one of the builtin things you can do is generate PostScript visualizations of them. Check this out:

Maybe Google's new "Rune" language will become prevalent https://github.com/google/rune, which supports SoA.

It looks like Rune still has a bitwise XOR operator: @

That innovation does seem like a potential footgun.

Why do they call it "Python-inspired" if it looks like C++?
