dreamc v0.5.0

Dream

An experimental WebAssembly language. Designed to make writing high performance web apps fun for individuals and teams alike.

/** Find the value of the fibonacci sequence at index n */
fn fib(n: i32) -> i32 =
    if n < 2 { n }
    else { fib(n - 1) + fib(n - 2) }

/** All binary programs have a main function */
fn main() -> Void = {
    var index = 0
    while index <= 15 {

        // Print fibonacci sequence at index using UFCS.
        index.fib().print()

        // Standard call syntax is also supported.
        // i.e print(fib(index))

        index = index + 1
    }
}

Disclaimer Dream is in it's very early stages and should not be used for production applications. Most MVP features have not been implemented yet. The language does run and compile though. So feel free to play around.

Features:

• First class WebAssembly support
• Expression oriented syntax
• UFCS
• Support for OOP and Functional paradigms
• Strongly typed, with type inference
• Macros
• Optional GC
