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 / "

See /r/ProgrammingLanguages for specific examples

The Pure Programming Language (2022) (agraef.github.io)

Pure is a modern-style functional programming language based on term rewriting. It offers equational definitions with pattern matching, full symbolic rewriting capabilities, dynamic typing, eager and lazy evaluation, lexical closures, built-in list and matrix support and an easy-to-use C interface. The interpreter uses LLVM as a backend to JIT-compile Pure programs to fast native code.

...

For instance, here is a famous equation which you hopefully remember from high school algebra: (x+y)^2 = x^2+2xy+y^2; Again, you can just paste this line into the interpreter, and lo and behold, it just works in Pure:
(a*x+(y+b))^2;
(a*x)^2+2*(a*x)*(y+b)+(y^2+2*y*b+b^2)
Now this might seem like an arcane feature, but many if not most real-world programming tasks involve a substantial amount of symbolic computations these days, and as a term rewriting language, Pure makes those easy. E.g., check the units.pure script in the sources for a practical example. (More examples from the sources can be found on the Examples wiki page.)

Maybe they also include the C interop in that library support?
