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

Borgo is a new programming language that compiles to Go.

use fmt

enum NetworkState<T> {
    Loading,
    Failed(int),
    Success(T),
}

struct Response {
    title: string,
    duration: int,
}

fn main() {
    let res = Response {
        title: "Hello world",
       duration: 0,
    }

    let state = NetworkState.Success(res)

    let msg = match state {
        NetworkState.Loading => "still loading",
        NetworkState.Failed(code) => fmt.Sprintf("Got error code: %d", code),
        NetworkState.Success(res) => res.title,
    }

    fmt.Println(msg)
}

The intro doesn't have any real information. Why? What are its strengths? What is its audience?

Honestly it's quite obvious from the code snippet and the diagram but I can spell it out:

Go is a quite nice language but mainly because of its fantastic infrastructure. Compilation is very fast, cross compilation is trivial, it makes static binaries that don't even depend on glibc (compatibility nightmare on Linux), the module system is great, it even has built in fuzzing support - how many languages have that?

However the language is decidedly meh. It doesn't have some modern features that make programming much more pleasant. Notably:

Tagged unions, aka discriminated unions, aka sum types. These vastly improve type safety and are just very convenient.
Expression based. People can go overboard with this but I don't think anyone who has used an expression based language would want to go back. Some common tasks like the let msg in the example are just so tedious if match is a statement.
Optional. Somehow Go copied the billion dollar mistake. In fairness languages like Typescript and Rust weren't around when Go was designed so it may not have been obvious to the authors that this was the way to go.

So this is basically a do-over of Go but if it had been designed by someone familiar with these modern best practices in language design.
