Documentation, here: https://www.thewallsoft.com/luci-lang/doc/index.html

Luci is an optionally typed scripting language. It is developed in C++, has no external dependencies and is about learning what it takes to create a realistic (scripted) programming language. It has its roots in https://interpreterbook.com/.

Luci has following:

• A syntax that is a mix of C, C++ and Python
• Supports imperative, object-oriented and functional style of programming
• Supports optional typing
• REPL

Examples

Hello world

let const words : [str] = [
    "Hello",
    "world"];

print(" ".join(words));

Fibonacci

let fibonacci = fn(x : int) -> int {
    if (x<=1) {
        return x;
    }
    return fibonacci(x-1)+fibonacci(x-2)
}

fibonacci(10);

Optional Typing

let words = [
    "Hello",
    "world"];

words[0] = 5.0;     // this is ok

let const const_words : [str] = [
    "Hello",
    "world"];

const_words[0] = 5.0;     // this is an error, because of const and type mismatch of double vs str
