凹语言™（凹读音“Wa”）是 针对 WASM 平台设计的通用编程语言，同时支持 Linux、macOS 和 Windows 等主流操作系统和 Chrome 等浏览器环境，同时也支持作为独立Shell脚本和被嵌入脚本模式执行。
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.

## 本地安装和测试 (Install and Run):
1. `go install github.com/wa-lang/wa@latest`
2. `wa init -name=_examples/hi`
3. `wa run _examples/hi`
> 项目尚处于原型开源阶段，如果有共建和PR需求请参考 [如何贡献代码](https://wa-lang.org/community/contribute.html)。
> The Wa project is still in very early stage. If you want to submit PR, please read the [Contribution Guide(Chinese)](https://wa-lang.org/community/contribute.html).
## 例子: 凹语言 (Example: Print 凹语言)
打印字符和调用函数(Print rune and call function)：
```
fn main {
println("你好，凹语言！")
println(add(40, 2))
}
fn add(a: i32, b: i32) => i32 {
return a+b
}
```
运行并输出结果 (Execute the program):
```
$ go run main.go hello.wa
你好，凹语言！
42
```
## 例子: 打印素数 (Example: Print Prime)
打印 30 以内的素数 (Print prime numbers up to 30):
```

fn 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)
}
}
}
```
运行并输出结果 (Execute the program):
```
$ go run main.go run _examples/prime
2
3
5
7
11
13
17
19
23
29
```

## 作为脚本执行 (Execut as a script)
凹语言本身也可以像 Lua 语言被嵌入 Go 宿主语言环境执行 (The Wa language itself can also be executed like the Lua language embedded in the Go host locale):
```
package main
import (
"fmt"
"github.com/wa-lang/wa/api"
)
func main() {
output, err := api.RunCode("hello.wa", "fn main() { println(40+2) }")
fmt.Print(string(output), err)
}
```
注：作为脚本执行目前只支持本地环境。(Note: Executing as a script currently only supports native environments.)
