Vesper

Vesper is a statically typed programming language designed for scientific computing, high-performance computing, and systems-oriented software.

Its syntax is intended to remain simple while providing strong foundations for numerical programming and future compiler optimizations.

Example

fn factorial(n: int): int {
    if (n <= 1) {
        return 1;
    }

    return n * factorial(n - 1);
}

let result = factorial(10);
print(result);

Current implementation

The current Vesper implementation includes a lexer, parser, AST, static type checker, tree-walk interpreter, and formatter.

It also supports recursive modules with imports resolved relative to the file that declares each import. The formatter is available as vspfmt, and the Vesper VS Code extension provides syntax highlighting, autocomplete, formatting, and a Run command.

The native compiler and LLVM backend are future development goals.
