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

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.

I think S-expresions are an often overlooked encoding and when used on code it results in a lisp dialect.
The main advantages are no ambiguity, easy parsing/interpretation and lisp being an established language family, the main disadvantage is a lot of parentheses.

Now for some barely relevant rambling: By implementing your own simple lisp dialect you can tailor it to your own needs by simply not implementing IO or even limiting computational complexity by limiting recursion and not allowing first class functions.

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 / "
