Hello!

This is the current Lemmy equivalent of https://www.reddit.com/r/ProgrammingLanguages/.

The content and rules are the same here as they are over there. Taken directly from the /r/ProgrammingLanguages overview:

This community is dedicated to the theory, design and implementation of programming languages.

Be nice to each other. Flame wars and rants are not welcomed. Please also put some effort into your post.

This isn't the right place to ask questions such as "What language should I use for X", "what language should I learn", and "what's your favorite language". Such questions should be posted in /c/learn_programming or /c/programming.

This is the right place for posts like the following:

"Check out this new language I've been working on!"
"Here's a blog post on how I implemented static type checking into this compiler"
"I want to write a compiler, where do I start?"
"How does the Java compiler work? How does it handle forward declarations/imports/targeting multiple platforms/?"
"How should I test my compiler? How are other compilers and interpreters like gcc, Java, and python tested?"
"What are the pros/cons of ?"
"Compare and contrast vs. "
"Confused about the semantics of this language"
"Proceedings from PLDI / OOPSLA / ICFP / "

Question: Any Serialization Lang for Pure Functions (lemm.ee)

submitted 2 years ago by jeffhykin@lemm.ee to c/programming_languages@programming.dev

7 comments fedilink hide all child comments

JSON and YAML work great for passing data between languages.

However, sometimes, I have a pure function like y = mx + b, that I would like to pass between languages (for making plots).

What operators should be available? I think jsonnet's standard library(skip to the math operators) is the perfect example of a useful set of operations that could be shared across basically all programming languages. The operations would take/return json values rather than working with language-specific data types.

My question is does such a language exist already?

Close candidates:

Dhall and jsonnet are pure languages that generate json. But AFAIK they can't actually serialize pure functions. They can only use pure functions as a shorthand for generating json. I want to actually save/send functions over the wire.

What do you think about compiling to wasm, for these logical inter-exchanges?

[–] jeffhykin@lemm.ee 1 points 2 years ago (1 children)

I think that's actually a pretty good idea.

I could, right now, create the function in wasm, put it in yaml with a !wasm tag (or maybe a more specific tag) then the deserializer could detect it, load it, and wrap it in a function.

Check out the ABI concept, if you haven't found it yet:

I would actually intentionally not want any ABI like wasi or emscriptem. I'd like the serialization format to not care about the platform at all (e.g. the function should run the same on any operating system, browser, embedded device, etc).

[–] DrDeadCrash@programming.dev 1 points 2 years ago

Wouldn't this serialization format need to be implemented in every language that that needed interoperation? How does that differ from an ABI?
