Example

use valk:http

fn handler(req: http:Request) http:Response {
    return http:Response.html("Hello world!")
}

fn main() {
    let host = "127.0.0.1"
    let port : u16 = 9000
    let s = http:Server.new(host, port, handler) ! {
        println("Failed to initialize http server")
        return
    }
    println("HTTP server - http://" + host + ":" + port)
    s.start()
}

Amazing performance

Valk can compete with the fastest languages out there. Our GC performance is amazingly fast. Visit our github page to see some of our benchmarks.

Why did we make Valk?

We wanted to create a language that has the perfect balance between simplicity and performance. We didnt feel like existing languages were doing a good job at this except for Go. But Go, although very good, has it's own oddities. We wanted to see if we could do it better.

What can we do better?
- A faster GC (no mark/sweep performance bottleneck)
- Better generics
- A package manager similar to npm/composer
- Different way to handle public/readonly/private
- Thread local storage variables
- Simple/short syntax for error handling
- Allow the use of c-libraries

Language details

- Open source
- MIT license
- LLVM backend
- Self hosted (can compile itself)
- Persistent GC (keeps state, no mark/sweep)
- Semi-stackful coroutines
