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

Thank you!

When you say Haskell and Rust have a similar feature, do you mean how Haskell compiles down to Haskell Core? Can you provide a tiny bit more detail on that point? I adore Haskell.

Yes. Unfortunately I’m not very familiar with GHC and HLS internals.

What I do know is that when GHC is invoked with a certain flag, as it compiles each Haskell file, it generates a .hie file with intermediate data which can be used by IDEs. So HLS (and maybe JetBrains Haskell) works by invoking GHC to parse and type-check the active haskell file, and then queries the .hie file to get diagnostics, symbol lookups, and completions. There’s also a program called hiedb which can query .hie files on the command line.

Rust’s language server is completely different (salsa.rs). The common detail is that both of them have LLVM IR, but also higher-level IRs, and the compiler passes information in the higher-level IRs to IDEs for completions/lookups/diagnostics/etc. (in Haskell via the generated .hie files)

Thanks again. 🙏
