Wa is a general-purpose programming language designed for developing robustness and maintainability WebAssembly software. Instead of requiring complex toolchains to set up, you can simply go install it - or run it in a browser.

Print rune and call function：

# Copyright @2019-2022 The Wa author. All rights reserved.

import "fmt"

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

	fmt.Println(1+1)
}

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

Execute the program:

$ go run main.go hello.wa 
hello, Wa!
42
2

Print prime numbers up to 30:

func main {
	for n := 2; n <= 30; n = n + 1 {
		var 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:

$ go run main.go run _examples/prime

The Wa language itself can also be executed like the Lua language embedded in the Go host locale:

package main

import (
	"fmt"
	"wa-lang.org/wa/api"
)

func main() {
	output, err := api.RunCode(api.DefaultConfig(), "hello.wa", code)
	fmt.Print(string(output), err)
}

Note: Executing as a script currently only supports native environments.
