+<h1 align="center">使用 Clap 完成参数解析</h1>
+<p align="center">
+    用 clap 做更复杂的参数解析
+</p>
+
+Picker 适合轻量级的参数提取，但当参数数量多、有复杂的校验规则、或者需要自动生成 `--help` 时，可以接入 [clap](https://crates.io/crates/clap)。
+
+## 开启 clap 特性
+
+```toml
+[dependencies.mingling]
+features = ["clap"]
+ 
+[dependencies.clap]
+version = "4"
+features = ["derive", "color"]
+```
+ 
+## dispatcher_clap
+
+`#[dispatcher_clap]` 加在 `clap::Parser` 结构体上，自动生成 Dispatcher：
+
+```rust
+// Features: ["clap"]
+// Dependencies:
+// clap = "4"
+@@@ use mingling::macros::dispatcher_clap;
+#[derive(Default, clap::Parser, Groupped)]
+#[dispatcher_clap("greet", CMDGreet, help = true, error = ErrorGreetParsed)]
+pub struct EntryGreet {
+    #[clap(default_value = "World")]
+    name: String,
+    #[arg(short, long, default_value_t = 1)]
+    repeat: i32,
+}
+ 
+#[renderer]
+fn render_greet(greet: EntryGreet) {
+    let count = greet.repeat.max(0) as usize;
+    r_print!("Hello, ");
+    for _ in 0..count {
+        r_print!("{} ", greet.name);
+    }
+    r_println!("!");
+}
+ 
+#[renderer]
+fn render_greet_parse_failed(err: ErrorGreetParsed) {
+    r_println!("{}", *err);
+}
+```
+ 
+## 与 BasicProgramSetup 配合
+
+如果需要 `--help` 支持，在 main 中注册 `BasicProgramSetup` 并设置 clap 帮助的输出模式：
+
+```rust
+// Features: ["clap"]
+// Dependencies:
+// clap = "4"
+@@@use mingling::setup::BasicProgramSetup;
+@@@use mingling::macros::dispatcher_clap;
+@@@#[derive(Default, clap::Parser, Groupped)]
+@@@#[dispatcher_clap("greet", CMDGreet)]
+@@@pub struct EntryGreet {
+@@@    name: String,
+@@@}
+@@@#[renderer]
+@@@fn render_greet(greet: EntryGreet) {
+@@@    r_println!("Hello, {}!", greet.name);
+@@@}
+@@@
+fn main() {
+    let mut program = ThisProgram::new();
+    program.with_setup(BasicProgramSetup);
+    program.stdout_setting.clap_help_print_behaviour =
+        mingling::ClapHelpPrintBehaviour::WriteToRenderResult;
+    program.with_dispatcher(CMDGreet);
+    program.exec_and_exit();
+}
+```
