Brim

Brim is a small, statically typed programming language by Ordnary, for command-line tools and backend services. It compiles to native executables through LLVM, and comes with one brim command for everything else: running, testing, formatting, managing dependencies and editor support.

fn main() {
    let names: List[string] = ["Ada", "Grace", "Linus"]
    for name in names {
        print("Hello, " + name + "!")
    }
}

Hello, Ada!
Hello, Grace!
Hello, Linus!

Brim aims to be:

• Explicit. Every parameter, result and field has a declared type, a variable has the type of its value, values are never converted implicitly, and errors are values (Result with the ? operator), not exceptions.
• Predictable. Structs, lists and maps are values: assigning one copies it (cheaply, by copy-on-write). Memory is managed by reference counting, without a garbage collector.
• Helpful. Every diagnostic has a code, points at the source and usually says how to fix the problem. Run-time errors show the call stack.

Brim is heading for 1.0, edition 2026: from 1.0 the language, the standard library and the brim command are stable (Releasing). The roadmap lists what comes next.
