+## 语法示例
+
+### 基础语法
+
+```vety
+// 变量声明
+let a: i32 = 1
+const b: i32 = 2
+
+// 数组
+let arr: i32[] = [64, 34, 25, 12, 22, 11, 90]
+
+// Map对象
+let m: any = {
+    a: 6,
+    b: 9,
+    c: {
+        d: 9
+    }
+}
+
+// 函数定义
+func add(a: i32, b: i32): i32 {
+    return a + b
+}
+```
+
+### 控制流
+
+```vety
+// if 语句
+if (condition) {
+    // ...
+} else if (condition2) {
+    // ...
+} else {
+    // ...
+}
+
+// for 循环
+for (let i: i32 = 0; i < n; i++) {
+    // ...
+}
+
+// while 循环
+while (condition) {
+    // ...
+}
+```
+
+### 错误处理
+
+```vety
+try {
+    // 可能抛出异常的代码
+} catch (e) {
+    // 处理异常
+}
+```

+# Vety语言入门指南
+
+## 简介
+
+Vety是一门现代化的编程语言，旨在提供简洁、高效且安全的编程体验。它结合了静态类型系统的安全性和动态语言的灵活性，使开发者能够快速构建可靠的应用程序。
+
+## 设计理念
+
+- **简洁性**：语法简单直观，减少不必要的复杂性
+- **类型安全**：强大的静态类型系统，在编译时捕获潜在错误
+- **性能优先**：高效的运行时性能，适合构建各类应用
+- **原生集成**：良好的原生函数支持，易于与现有系统集成
+- **模块化**：强大的模块系统，支持代码复用和组织
+
+## 快速开始
+
+### 1. 基本语法
+
+```vety
+// 变量声明
+let message: string = "Hello, Vety!"
+let number: i32 = 42
+
+// 函数定义
+func add(a: i32, b: i32): i32 {
+    return a + b
+}
+
+// 条件语句
+if (number > 0) {
+    print("Positive number")
+} else {
+    print("Non-positive number")
+}
+
+// 循环
+for (i: i32 = 0; i < 5; i++) {
+    print(i)
+}
+```
+
+### 2. 类型系统
+
+Vety提供了丰富的内置类型：
+
+- **基本类型**：
+  - `i32`：32位整数
+  - `i64`：64位整数
+  - `f64`：64位浮点数
+  - `bool`：布尔值
+  - `string`：字符串
+  - `void`：无返回值
+
+- **复合类型**：
+  - `array<T>`：数组
+  - `map<K, V>`：映射
+  - 自定义结构体
+
+### 3. 错误处理
+
+Vety使用try-catch机制处理错误：
+
+```vety
+try {
+    let result = some_risky_operation()
+} catch(e) {
+    print("操作失败")
+}
+```
+
+### 4. 模块系统
+
+```vety
+// 导入标准库模块
+import io
+import math
+
+// 使用模块功能
+let random_number = math.random(1, 100)
+io.print("随机数：" + random_number)
+```
+
+### 5. 内置函数
+
+Vety提供了一系列实用的内置函数：
+
+- `print()`：输出信息
+- `read_line()`：读取用户输入
+- `len()`：获取集合长度
+- `type_of()`：获取值的类型
+
+## 最佳实践
+
+1. **命名规范**
+   - 变量和函数使用小写字母和下划线
+   - 类型名使用大驼峰命名法
+
+2. **代码组织**
+   - 相关功能放在同一模块中
+   - 适当使用注释说明代码功能
+
+3. **错误处理**
+   - 合理使用try-catch处理异常
+   - 提供有意义的错误信息
+
+4. **性能优化**
+   - 避免不必要的内存分配
+   - 合理使用循环和递归
+
+## 下一步
+
+- 阅读更详细的[语法指南](01_basic_syntax.md)
+- 了解[控制流](02_control_flow.md)
+- 学习[函数和模块](03_functions_and_modules.md)
+- 探索[复合类型](04_composite_types.md)
+
+## 示例项目
+
+查看`demo`目录中的示例代码，了解更多Vety语言的实际应用：
+
+- `hello.vt`：基本语法示例
+- `array.vt`：数组操作示例
+- `function.vt`：函数使用示例
+- `try-catch.vt`：错误处理示例

+# Vety语言基础语法
+
+## 1. 变量声明
+
+Vety语言使用`let`关键字声明变量，使用`const`关键字声明常量。
+
+```vety
+// 变量声明
+let name: string = "Vety"
+let age: i32 = 1
+
+// 常量声明
+const PI: f64 = 3.14159
+```
+
+## 2. 基本数据类型
+
+### 2.1 整数类型
+
+Vety提供了有符号和无符号整数类型：
+
+- 有符号整数：
+  - `i8`: 8位有符号整数 (-128 到 127)
+  - `i16`: 16位有符号整数 (-32,768 到 32,767)
+  - `i32`: 32位有符号整数 (-2,147,483,648 到 2,147,483,647)
+  - `i64`: 64位有符号整数
+
+- 无符号整数：
+  - `u8`: 8位无符号整数 (0 到 255)
+  - `u16`: 16位无符号整数 (0 到 65,535)
+  - `u32`: 32位无符号整数 (0 到 4,294,967,295)
+  - `u64`: 64位无符号整数
+
+```vety
+let age: i32 = 25
+let distance: u64 = 1000000
+```
+
+### 2.2 浮点数类型
+
+- `f32`: 32位浮点数
+- `f64`: 64位浮点数
+
+```vety
+let pi: f32 = 3.14159
+let e: f64 = 2.71828
+```
+
+### 2.3 布尔类型
+
+`bool`类型表示布尔值，可以是`true`或`false`。
+
+```vety
+let is_valid: bool = true
+let has_error: bool = false
+```
+
+### 2.4 字符串类型
+
+`string`类型用于表示文本数据。字符串使用双引号(")包围。
+
+```vety
+let message: string = "Hello, Vety!"
+let name: string = "John"
+```
+
+字符串支持转义字符：
+- `\n`: 换行
+- `\t`: 制表符
+- `\r`: 回车
+- `\"`: 双引号
+- `\\`: 反斜杠
+
+### 2.5 void类型
+
+`void`类型表示没有返回值的函数的返回类型。
+
+```vety
+func print_message(): void {
+    // 函数体
+}
+```
+
+## 3. 类型推断
+
+Vety支持类型推断，当变量的类型可以从初始值推断出来时，可以省略类型注解：
+
+```vety
+let name = "Vety"    // 推断为string类型
+let age = 25        // 推断为i32类型
+let is_valid = true // 推断为bool类型
+```
+
+## 4. 基本运算符
+
+### 4.1 算术运算符
+
+- `+`: 加法
+- `-`: 减法
+- `*`: 乘法
+- `/`: 除法
+- `%`: 取模
+
+### 4.2 比较运算符
+
+- `==`: 等于
+- `!=`: 不等于
+- `<`: 小于
+- `>`: 大于
+- `<=`: 小于等于
+- `>=`: 大于等于
+
+### 4.3 逻辑运算符
+
+- `&&`: 逻辑与
+- `||`: 逻辑或
+- `!`: 逻辑非
+
+### 4.4 位运算符
+
+- `&`: 按位与
+- `|`: 按位或
+- `^`: 按位异或
+- `~`: 按位取反
+
+## 5. 注释
+
+Vety支持两种注释方式：
+
+```vety
+// 单行注释
+
+/*
+多行注释
+可以跨越多行
+*/
+```

+# Vety语言控制流程
+
+## 1. 条件语句
+
+### 1.1 if-else语句
+
+Vety使用`if`和`else`关键字进行条件控制：
+
+```vety
+let score: i32 = 85
+
+if (score >= 90) {
+    print("优秀")
+} else if (score >= 80) {
+    print("良好")
+} else if (score >= 60) {
+    print("及格")
+} else {
+    print("不及格")
+}
+```
+
+条件表达式必须是布尔类型，Vety不会进行隐式的真值转换。
+
+### 1.2 条件表达式的组合
+
+可以使用逻辑运算符组合多个条件：
+
+```vety
+let age: i32 = 25
+let has_ticket: bool = true
+
+if (age >= 18 && has_ticket) {
+    print("允许入场")
+} else {
+    print("不允许入场")
+}
+```
+
+## 2. 循环语句
+
+### 2.1 while循环
+
+`while`循环在条件为真时重复执行代码块：
+
+```vety
+let count: i32 = 0
+
+while (count < 5) {
+    print(count)
+    count = count + 1
+}
+```
+
+### 2.2 for循环
+
+Vety的`for`循环支持遍历数组和范围：
+
+```vety
+// 遍历数组
+let numbers: array = [1, 2, 3, 4, 5]
+
+for (let i: i32 = 0; i < numbers.len; i++) {
+    print(numbers[i])
+}
+```
+
+## 3. 循环控制
+
+### 3.1 break语句
+
+使用`break`语句可以提前退出循环：
+
+```vety
+let i: i32 = 0
+while (true) {
+    if (i >= 5) {
+        break
+    }
+    print(i)
+    i = i + 1
+}
+```
+
+### 3.2 continue语句
+
+使用`continue`语句可以跳过当前循环的剩余部分，直接进入下一次循环：
+
+```vety
+for (let i: i32 = 0; i < 10; i++) {
+    if (i % 2 == 0) {
+        continue  // 跳过偶数
+    }
+    print(i)     // 只打印奇数
+}
+```
+
+## 4. 错误处理
+
+### 4.1 try-catch语句
+
+Vety使用`try`和`catch`进行错误处理：
+
+```vety
+try {
+    // 可能产生错误的代码
+    let result = dangerous_operation()
+} catch(e) {
+    // 错误处理代码
+    print("操作失败")
+}
+```
+
+### 4.2 错误传播
+
+函数可以使用返回值来传播错误：
+
+```vety
+func divide(a: i32, b: i32): i32 {
+    if b == 0 {
+        throw "除数不能为零"
+    }
+    return a / b
+}
+
+try {
+    let result = divide(10, 0)
+} catch(e) {
+    print("除法运算失败")
+}
+```

+# Vety语言函数和模块
+
+## 1. 函数定义
+
+### 1.1 基本函数定义
+
+使用`func`关键字定义函数：
+
+```vety
+func add(a: i32, b: i32): i32 {
+    return a + b
+}
+
+// 无返回值的函数
+func print_message(msg: string): void {
+    print(msg)
+}
+```
+
+### 1.2 函数参数
+
+函数参数必须指定类型：
+
+```vety
+func greet(name: string, age: i32): string {
+    return "Hello, " + name + "! You are " + age + " years old."
+}
+```
+
+### 1.3 返回值
+
+- 函数必须指定返回值类型
+- 使用`return`语句返回值
+- 如果函数不需要返回值，使用`void`类型
+
+```vety
+func calculate_area(width: f64, height: f64): f64 {
+    return width * height
+}
+```
+
+## 2. 原生函数
+
+使用`native`关键字声明原生函数，这些函数由底层实现：
+
+```vety
+native func print(message: string): void
+native func read_line(): string
+```
+
+## 3. 模块系统
+
+### 3.1 导入模块
+
+使用`import`关键字导入其他模块：
+
+```vety
+import io  // 导入标准库的io模块
+import math // 导入数学模块
+```
+
+### 3.2 模块别名
+
+可以使用`as`关键字为导入的模块指定别名：
+
+```vety
+import module_name as alias_name
+```
+
+## 4. 函数调用
+
+### 4.1 基本调用
+
+```vety
+let result = add(5, 3)        
+print("Hello, World!")       
+```
+
+### 4.2 模块函数调用
+
+```vety
+let current_time = time.now() // 调用模块中的函数
+let random_number = math.random(1, 100)
+```
+
+## 5. 注解
+
+使用`@`符号添加函数注解：
+
+```vety
+@deprecated
+func old_function(): void {
+    // 已废弃的函数
+}
+
+@test
+func test_feature(): void {
+    // 测试函数
+}
+```
+
+## 6. 错误处理
+
+函数可以抛出错误，调用者需要处理这些错误：
+
+```vety
+func divide(a: f64, b: f64): f64 {
+    if (b == 0) {
+        throw "Division by zero"
+    }
+    return a / b
+}
+
+try {
+    let result = divide(10.0, 0.0)
+} catch(e) {
+    print("除法运算失败")
+}
+```
+
+## 7. 最佳实践
+
+- 函数名使用小写字母和下划线
+- 函数应该只做一件事情
+- 参数数量不宜过多
+- 适当添加注释说明函数功能
+- 处理所有可能的错误情况
+
+```vety
+// 好的函数示例
+func calculate_average(numbers: array<): f64 {
+    if (numbers.length == 0) {
+        throw "Empty array"
+    }
+    
+    let sum: f64 = 0.0
+    for num in numbers {
+        sum = sum + num
+    }
+    return sum / numbers.length
+}
+```

+# Vety语言复合数据类型
+
+## 1. 数组（Array）
+
+### 1.1 数组声明
+
+数组是相同类型元素的有序集合，使用方括号`[]`表示：
+
+```vety
+// 显式类型声明
+let numbers: array = [1, 2, 3, 4, 5]
+
+// 空数组
+let empty_array: array = []
+
+// 类型推断
+let fruits = ["apple", "banana", "orange"]
+```
+
+### 1.2 数组访问
+
+使用索引访问数组元素（索引从0开始）：
+
+```vety
+let numbers = [10, 20, 30, 40, 50]
+
+// 访问元素
+let first = numbers[0]    // 10
+let second = numbers[1]   // 20
+
+// 修改元素
+numbers[2] = 35          // [10, 20, 35, 40, 50]
+```
+
+### 1.3 数组操作
+
+```vety
+// 获取数组长度
+let length = numbers.length
+
+// 遍历数组
+for num in numbers {
+    print(num)
+}
+
+// 使用索引遍历
+for (let i = 0; i < numbers.length; i++) {
+    print(numbers[i])
+}
+```
+
+## 2. 映射（Map）
+
+### 2.1 映射声明
+
+映射是键值对的集合，键和值可以是不同类型：
+
+```vety
+// 显式类型声明
+let scores: map<string, i32> = {
+    "Alice": 95,
+    "Bob": 87,
+    "Charlie": 92
+}
+
+// 空映射
+let empty_map: map<string, bool> = {}
+
+// 类型推断
+let config = {
+    "debug": true,
+    "port": 8080,
+    "host": "localhost"
+}
+```
+
+### 2.2 映射访问
+
+使用键访问映射中的值：
+
+```vety
+let scores = {"Alice": 95, "Bob": 87}
+
+// 访问值
+let alice_score = scores["Alice"]    // 95
+
+// 修改值
+scores["Bob"] = 90                  // {"Alice": 95, "Bob": 90}
+
+// 添加新键值对
+scores["Charlie"] = 88              // {"Alice": 95, "Bob": 90, "Charlie": 88}
+```
+
+### 2.3 映射操作
+
+```vety
+// 检查键是否存在
+if "Alice" in scores {
+    print("Found Alice's score")
+}
+
+// 遍历映射
+for key in scores {
+    let value = scores[key]
+    print(key + ": " + value)
+}
+```
+
+## 3. 复合类型嵌套
+
+数组和映射可以相互嵌套，创建更复杂的数据结构：
+
+### 3.1 数组的数组
+
+```vety
+// 二维数组
+let matrix: array<array<i32>> = [
+    [1, 2, 3],
+    [4, 5, 6],
+    [7, 8, 9]
+]
+
+// 访问嵌套元素
+let value = matrix[1][2]    // 6
+```
+
+### 3.2 映射的数组
+
+```vety
+// 用户列表
+let users: array<map<string, string>> = [
+    {"name": "Alice", "email": "alice@example.com"},
+    {"name": "Bob", "email": "bob@example.com"}
+]
+
+// 访问嵌套数据
+let first_user_email = users[0]["email"]
+```
+
+### 3.3 映射的映射
+
+```vety
+// 嵌套配置
+let config: map<string, map<string, string>> = {
+    "database": {
+        "host": "localhost",
+        "port": "5432",
+        "name": "mydb"
+    },
+    "server": {
+        "host": "0.0.0.0",
+        "port": "8080"
+    }
+}
+
+// 访问嵌套值
+let db_host = config["database"]["host"]
+```
+
+## 4. 最佳实践
+
+- 选择合适的数据结构
+- 注意类型一致性
+- 处理边界情况
+- 合理使用嵌套
+
+```vety
+// 好的实践示例
+func process_scores(scores: map<string, i32>): f64 {
+    if scores.length == 0 {
+        return 0.0
+    }
+    
+    let total: i32 = 0
+    for name in scores {
+        total = total + scores[name]
+    }
+    return total / scores.length
+}
+```
