凹语言™（凹读音“Wa”）是 针对 WASM 平台设计的的通用编程语言，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.

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`

## 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() {
	print('凹')
	print('语')
	print('言')
	print('\n')

	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 
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):

```go
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.)
