nex

A lightweight, statically typed, compiled language. C/Go/Rust-flavoured syntax, no build boilerplate.

fn main() {
    print("hello, world");
}

Design goals

Lightweight

Small language, small runtime, fast compiles.

Statically typed

Everything is checked before it runs.

Familiar

C/Go/Rust-flavoured syntax; no surprises.

No ceremony

Local type inference, no header files, no build boilerplate.

Non-goals for v0.1: ownership/borrow checking, lifetimes, traits with dynamic dispatch, async, threads, macros, a central package registry. See Language Design for the full spec.

What works today

Area	Status
Lexer	done, with error recovery
AST	done: expressions, statements, items, types, patterns
Parser	done: expressions, statements and items
Interpreter	in progress: values, control flow, functions
Type checker	not started
Codegen	not started
CLI	`nex lex` works, everything else is a stub

The only working subcommand today dumps the token stream:

cargo run -p nex-driver -- lex examples/hello.nex

See Getting Started and the lexical structure reference for details.
