## 本地安装和测试:
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
打印字符和调用函数:
```wa
import "fmt"
fn main {
println("你好,凹语言!")
println(add(40, 2))
fmt.Println(1+1)
}
fn add(a: i32, b: i32) => i32 {
return a+b
}
```
运行并输出结果:
```
$ go run main.go hello.wa
你好,凹语言!
42
2
```
## 例子: 打印素数
打印 30 以内的素数:
```

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:
```
$ go run main.go run _examples/prime
2
3
5
7
11
13
17
19
23
29
```

## 作为脚本执行
凹语言本身也可以像 Lua 语言被嵌入 Go 宿主语言环境执行:
```
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)
}
```
注:作为脚本执行目前只支持本地环境。
