baobao-codegen-rust

Rust code generator for Bao CLI generator.

This crate generates Rust CLI applications using clap for argument parsing.

Usage

This crate is used internally by the baobao CLI tool. You typically don't need to use it directly.

use baobao_codegen_rust::Generator;
use baobao_codegen::LanguageCodegen;
use baobao_manifest::Manifest;
use std::path::Path;

let manifest = Manifest::from_file("bao.toml")?;
let generator = Generator::new(&manifest);

// Preview files without writing
let files = generator.preview();

// Generate files to disk
let result = generator.generate(Path::new("output"))?;

Generated Output

The generator produces a Rust CLI project:

output/
├── src/
│   ├── cli.rs          # CLI definition with clap derive macros
│   ├── context.rs      # Shared context (database pools, HTTP clients)
│   ├── main.rs         # Entry point and command dispatch
│   ├── commands/       # Command modules

│   └── handlers/       # Handler stubs for implementation
│       └── *.rs

Features

• Type-safe CLI - Uses clap derive macros for compile-time argument validation
• Handler Stubs - Generates handler functions with correct signatures
• Context Support - Generates context structs for database pools and HTTP clients
• Subcommands - Full support for nested command hierarchies
