我们刚刚创建了基本的入口，现在编写子命令: `list`
```rust
use mingling::prelude::*;
fn main() {
let mut program = ThisProgram::new();
program.exec_and_exit();
}
gen_program!();
```
---
```rust
use mingling::prelude::*;
fn main() {
let mut program = ThisProgram::new();
<<<<<<<<<< "所有的资源将在此处注册"
program.exec_and_exit();
}
gen_program!();
```
---
```rust
use mingling::prelude::*;
<<<<<<<<<< "让我们在此处注册一个分发器，将 list 命令分发到指定的入口"
fn main() {
let mut program = ThisProgram::new();
program.exec_and_exit();
}
gen_program!();
```
---
```rust
use mingling::prelude::*;
dispatcher!( <<<<<<<<<< "编写"
fn main() {
let mut program = ThisProgram::new();
program.exec_and_exit();
}
gen_program!();
```
---
```rust
use mingling::prelude::*;
dispatcher!("list", <<<<<<<<<< "编写命令名称"
fn main() {
let mut program = ThisProgram::new();
program.exec_and_exit();
}
gen_program!();
```
---
```rust
use mingling::prelude::*;
dispatcher!("list", CMDList <<<<<<<<<< "编写分发器名称"
fn main() {
let mut program = ThisProgram::new();
program.exec_and_exit();
}
gen_program!();
```
---
```rust
use mingling::prelude::*;
dispatcher!("list", CMDList => EntryList <<<<<<<<<< "编写入口名称"
fn main() {
let mut program = ThisProgram::new();
program.exec_and_exit();
}
gen_program!();
```
---
```rust
use mingling::prelude::*;
dispatcher!("list", CMDList => EntryList); <<<<<<<<<< "这样，list 命令的分发器 CMDList 就被注册了"
fn main() {
let mut program = ThisProgram::new();
program.exec_and_exit();
}
gen_program!();
```
---
```rust
use mingling::prelude::*; <<<<<<<<<< "dispatcher! 宏由 prelude 提供"
dispatcher!("list", CMDList => EntryList);
fn main() {
let mut program = ThisProgram::new();
program.exec_and_exit();
}
gen_program!();
```
---
```rust
use mingling::prelude::*;
dispatcher!("list", CMDList => EntryList);
fn main() {
let mut program = ThisProgram::new();
<<<<<<<<<< "Ok, 现在在此处为程序添加分发器"
program.exec_and_exit();
}
gen_program!();
```
---
```rust
use mingling::prelude::*;
dispatcher!("list", CMDList => EntryList);
fn main() {
let mut program = ThisProgram::new();
program.with_dispatcher( <<<<<<<<<< "使用 with_dispatcher 为程序添加分发器"
program.exec_and_exit();
}
gen_program!();
```
---
```rust
use mingling::prelude::*;
dispatcher!("list", CMDList => EntryList);
fn main() {
let mut program = ThisProgram::new();
program.with_dispatcher(CMDList); <<<<<<<<<< "添加刚创建的分发器 CMDList"
program.exec_and_exit();
}
gen_program!();
```
---
至此，`list` 子命令便已被注册到程序
```rust
use mingling::prelude::*;
dispatcher!("list", CMDList => EntryList);
fn main() {
let mut program = ThisProgram::new();
program.with_dispatcher(CMDList);
program.exec_and_exit();
}
gen_program!();
```
