Wa (Chinese name "凹", which pronounced "Wa") 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 is in the engineering trial stage.
Note: The Wa compiler source files are distributed under the AGPL-v3 license. The Wa standard library is licensed under the MIT license. The programs you develop using the Wa language can be safely used commercially without open source. If you want to integrate the Wa compiler code into your own project, but do not want to be restricted by the infectiousness of AGPL-v3, you can contact us to customize the license agreement for you.
The project is still in the prototype stage. If you have co-construction or PR needs, please refer to How to contribute. We no longer accept PRs for modifications to third-party libraries.

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

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 AIChrome builtin Gemini Nano Demo:
import "ai"
func main {
ai.RequestSession(func(session: ai.Session){
session.PromptAsync("Who are you?", func(res: string) {
println(res)
})
})
}
