# RustDDS-Gen | |||
RustDDS-Gen 是一个用于将 IDL(接口定义语言)文件转换为 Rust 代码的工具。该工具专为 RustDDS 项目设计,支持解析 IDL 文件并生成相应的 Rust 结构体、枚举、常量等。 | |||
## 项目概述 | |||
RustDDS-Gen 提供了一个完整的 IDL 到 Rust 代码的转换流程,主要包括: | |||
- IDL 文件解析(基于 pest 解析器) | |||
- 语法树(AST)构建和处理 | |||
- Rust 代码生成 | |||
- 命令行界面,支持多种选项 | |||
## 功能特性 | |||
- 支持解析复杂的 IDL 文件,包括: | |||
- 模块(module)和嵌套模块 | |||
- 结构体(struct) | |||
- 枚举(enum) | |||
- 常量(const) | |||
- 类型定义(typedef) | |||
- 接口(interface) | |||
- 联合类型(union) | |||
- 序列(sequence) | |||
- 支持各种 IDL 数据类型,如 string、octet、long、double 等 | |||
- 支持参数方向(in、out、inout) | |||
- 提供详细的解析和代码生成日志 | |||
- 支持调试选项,如打印语法树、保存语法树到文件等 | |||

## 依赖项 | |||
- pest (2.8): 用于解析 IDL 文件 | |||
- pest_derive (2.8): 用于派生 pest 解析器 | |||
- clap (4.4): 用于命令行参数解析 | |||
- serde (1.0): 用于序列化和反序列化 | |||
- serde_json (1.0): 用于 JSON 处理 | |||
- anyhow (1.0): 用于错误处理 | |||
- thiserror (2.0.12): 用于自定义错误类型 | |||
- regex (1.11.1): 用于正则表达式处理 | |||
## 使用方法 | |||
### 基本用法 | |||
```bash | |||
rustdds-gen --input <IDL文件路径> --output <Rust文件输出路径> | |||
``` | |||
### 命令行选项 | |||
- `-i, --input <文件路径>`: 指定输入的 IDL 文件 | |||
- `-o, --output <文件路径>`: 指定输出的 Rust 文件 | |||
- `-d, --debug`: 启用调试输出 | |||
- `--parse-only`: 只解析语法,不生成代码 | |||
- `--verbose`: 打印详细的解析过程 | |||
- `--print-ast`: 打印语法树 | |||
- `--dump-ast <文件路径>`: 将解析结果保存到文件 | |||
### 示例 | |||
```bash | |||
# 基本用法 | |||
rustdds-gen --input test.idl --output test_output.rs | |||
# 调试模式 | |||
rustdds-gen --input test.idl --output test_output.rs --debug | |||
# 只解析不生成代码 | |||
rustdds-gen --input test.idl --output test_output.rs --parse-only | |||
# 保存语法树到文件 | |||
rustdds-gen --input test.idl --output test_output.rs --dump-ast ast.json | |||
``` | |||
## IDL 支持特性 | |||
RustDDS-Gen 支持以下 IDL 特性: | |||
- 基本数据类型:boolean, char, octet, short, long, float, double, string 等 | |||
- 自定义类型:struct, enum, typedef, union | |||
- 模块和嵌套模块 | |||
- 常量定义 | |||
- 接口和方法 | |||
- 参数方向(in, out, inout) | |||
- 序列(sequence) | |||
- 有限长度字符串(string<N>) | |||
## 开发指南 | |||
### 构建项目 | |||
```bash | |||
cargo build | |||
``` | |||
### 运行测试 | |||
```bash | |||
cargo test | |||
``` | |||
### 添加新的 IDL 特性支持 | |||
1. 在 `src/parser/idl.pest` 中添加新的语法规则 | |||
2. 在 `src/parser/mod.rs` 中添加相应的解析函数 | |||
3. 在 `src/codegen/mod.rs` 中添加相应的代码生成函数 | |||
## 许可证 | |||
[待定] | |||
## 贡献指南 | |||
欢迎提交问题报告和拉取请求。对于重大更改,请先开启一个问题进行讨论。 | |||
## 未来计划 | |||
- 支持更多 IDL 特性 | |||
- 改进错误处理和报告 | |||
- 添加更多单元测试和集成测试 | |||
- 支持生成序列化/反序列化代码 | |||
- 支持生成 DDS 相关代码 |
