StaticScript
StaticScript是一门类TypeScript的静态编译型语言
[English](./README.md) | 简体中文
## 安装
### Ubuntu
```shell
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/StaticScript/StaticScript/master/install-ubuntu.sh)"
```
或者
```shell
wget https://raw.githubusercontent.com/StaticScript/StaticScript/master/install-ubuntu.sh
sudo chmod +x install-ubuntu.sh
sudo /bin/bash install-ubuntu.sh
```
> 对于其他的Linux发行版, 你需要修改安装脚本才能正常安装
>
> 安装脚本需要sudo权限
### macOS
```shell
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/StaticScript/StaticScript/master/install-macos.sh)"
```
或者
```shell
wget https://raw.githubusercontent.com/StaticScript/StaticScript/master/install-macos.sh
sudo chmod +x install-macos.sh
sudo /bin/bash install-macos.sh
```
> 安装脚本需要sudo权限
### Windows
**_暂不支持_**
## 使用
首先编写像下面这样一个合法的StaticScript代码文件
```typescript
// test.ss
let content: string = "Hello World";
ss_println_string(content);
```
然后在命令行里执行下面这样的命令
```shell
staticscript test.ss -o test
./test
```
## 语言特性概要
### 变量和常量的声明
下面是一些变量声明
```typescript
let flag: boolean = true;
let count: number = 20;
let content: string = "Hello World";
```
得益于StaticScript的类型推导特性, 我们可以把上面的变量声明写成下面这样, 它们是等效的
```typescript
let flag = true;
let count = 20;
let content = "Hello World";
```
StaticScript的编译器可以巧妙地从变量的初始值推导出变量的类型
除了使用`let`声明变量外，还可以使用`const`声明常量
```typescript
const name = "StaticScript";
const age = 1;
const developing = true;
```
`let`和`const`的区别在于`const`声明的常量不能被修改
### 变量运算
可以使用多种多样的运算符对变量执行操作，包括算术运算、按位运算、逻辑运算、关系运算、赋值和字符串连接
```typescript
let a = 1;
let b = 2;
// 加减乘除
let sum = a + b;
let diff = a - b;
let product = a * b;
let quotient = a / b;
a = a << 1; // 等效于 `a <<= 1`
b = b >> 1; // 等效于 `b >>= 1`
let year = "2020", month = "08", day = "06";
let birthday = year + "/" + month + "/" + day;
```
### 控制流
```typescript
let a = 1;
let b = 100;
if (a < b) {
ss_println_string("b更大");
} else {
ss_println_string("b不比a大");
}
let max = a;
if (a < b) {
max = b;
}
```
### 循环
StaticScript支持使用`while`语句和`for`语句执行一些重复的操作
```typescript
// 计算[1, 100]间所有偶数的和
let sum1 = 0;
let i = 1;
while(i <= 100) {
if (i % 2 == 0) {
sum1 += i;
}
}
// 计算[1, 100]间所有整数的和
let sum2 = 0;
for(let i = 1; i <= 100; i++) {
sum2 += i;
}
```
### 函数
StaticScript支持在顶级范围内定义函数并在任何作用域内使用函数
```typescript
function add(a: number, b: number): number {
return a + b;
}
```
StaticScript可以通过return语句的表达式来推断返回类型, 因此上面的函数可以省略返回类型
需要注意的是，函数的参数类型必须显式声明, 不能省略
