Wa-lang is a general-purpose programming language designed for for WebAssembly. The goal is to provide a simple, reliable, easy-to-use, statically typed language for high-performance web applications. The code generator and runtime are fully independently developed (not dependent on external projects such as LLVM). Currently, Wa-lang is in the engineering trial stage.

Example: Print Wa

Print rune and call function：

import "fmt"

global year: i32 = 2023

func main {
	println("hello, Wa!")
	println(add(40, 2), year)

	fmt.Println(1+1)
}

func add(a: i32, b: i32) => i32 {
	return a+b
}

Execute the program:

$ wa run hello.wa 
hello, Wa!
42 2023
2

Example: Print Prime

Print prime numbers up to 30:

func main {
	for n := 2; n <= 30; n = n + 1 {
		isPrime: int = 1
		for i := 2; i*i <= n; i = i + 1 {
			if x := n % i; x == 0 {
				isPrime = 0
			}
		}
		if isPrime != 0 {
			println(n)
		}
	}
}

Execute the program:

$ cd waroot && wa run -target=wasi examples/prime

Example: Print Prime with Chinese syntax

Print prime numbers up to 30:

引于 "书"

【启】：
  // 输出30以内的素数
  从n=2，到n>30，有n++：
    设素=1
    从i=2，到i*i>n，有i++：
      设x=n%i
      若x==0则：
        素=0
      。
    。
    若素!=0则：
      书·曰：n
    。
  。
。

Output is the same as the previous example.

Example: Chrome Native AI

Chrome builtin Gemini Nano Demo:

import "ai"

func main {
	ai.RequestSession(func(session: ai.Session){
		session.PromptAsync("Who are you?", func(res: string) {
			println(res)
		})
	})
}
