I'd love to see a comparison to Haxe. https://haxe.org/
I wonder what performance and generated code size/quality look like.
It's a nice idea but the C portion expects an array of unknown size, no bounds checking possible at all and it's also not returned how large the PNM image is. I also don't understand why glib is needed here to get the array to work. It's also missing the stdint.h include to be able to use uint8_t.
Nice stuff, I'm working on something like Kaitai Struct, and it'll be very convenient to codegen to Fusion, to support multiple target languages.
However, what I like the least in all kind of software is underdocumentation. There's some reference, it's not bad, but actually it's just bunch of examples. If I want to find out exactly how a particular type or statement translates into a specific language, I'll have to dig into the code.

Why is this needed? I can't imagine that. I am sure writing code in fusion will produce C++ and Python code which is suboptimal and doesn't fit well in these languages.
Bad idea. It either takes a useless subset of all languages or do weird abstraction that wouldn't fit in a language otherwise.
How (and why) are you targeting OpenCL? It has quite a different programming model
As others say ; how does debugging work? I was a user of Haxe and Monkey and both had/have serious debugging issues; I think this can only work if it has an interpreter for itself (self hosted I guess ideally) with a proper debugger.
We seem to be regressing to the overuse of classes again.
Nice idea. I'm just wondering how to debug code written in fusion... probably you must focus on one of outputs, debug that one, and then back-fit the changes to the fusion source. :/
The syntax is so warm and simple, but not too simple. I like it, but I wonder how debuggable it can be, or if there is an interpreter for learning.
I was a bit surprised to see Ds logo there. Cool.
The idea it's good but hard to make it good. A universal language is hard to optimise for a particular language.
but not Haskell, guess they gave up on picking a string type =P
Wow, this is really fusion. I like it.
Now we need an UnFusion programming language that can take code written in any language and convert it into Fusion. With that, you could transform any project from language A into language B.
somewhat funny to the immature mind: "fut" - the name of the compiler binary - is austrian slang for vagina, but in the most obscene, vulgar way possible. a bit like "cunt", but worse.
I like it. I just wonder if today transpiling is better then Agentic Programming. Any specific use case where i should use it? With a good model, SKILLS.md, AGENTS.md and prompts I am able to do - allegedly - a better job then a transpiler, no?

What are the use cases? I am curious why Rust was not targeted.
Fusion is a programming language designed for implementing reusable components (libraries) for C, C++, C#, D, Java, JavaScript, Python, Swift, TypeScript and OpenCL C, all from single codebase.
It seems similar in concept to Haxe, but focused on writing libraries which are then called from the target language, rather than building your whole application in Fusion. Is that correct?
How are exceptions translated to languages which don't have exceptions, like C?
The amount of targets seems impressive, but I don't see anything resembling a standard library. Usually, it's in the standard library where diverging behavior between targets shows up. Haxe's documentation tends to cover those issues, and lets you know when a behavior is target-dependent, or unspecified. They do try to be consistent between targets whenever possible in a performant way.
Loreline[0] is a recent project which leverages Haxe to build a cross-platform library. Is there a similar project showcasing how Fusion can be used for that?
