//! Example Dispatch Tree
//!
//! > This example will introduce how to use `dispatch_tree`
//! > to optimize your command line lookup efficiency
//!
//! When the number of commands in your project increases, you can use `dispatch_tree` to complete command registration at compile time.
//! It will generate a trie for quickly finding related commands by prefix.
//!
//! Therefore, after enabling this feature,
//! `Program` will no longer store a Dispatcher list internally, and the `with_dispatcher` function will not be compiled.
//!
//! Run:
//! ```bash
//! cargo run --manifest-path examples/example-dispatch-tree/Cargo.toml --quiet -- cmd5
//! ```
//!
//! Output:
//! ```plaintext
//! It's works!
//! ```
//!
use mingling::prelude::*;
// --------- IMPORTANT ---------
// You have a large number of subcommands
dispatcher!("cmd1", CMD1 => Entry1);
dispatcher!("cmd2.sub1", CMD2Sub1 => Entry2Sub1);
dispatcher!("cmd2.sub2", CMD2Sub2 => Entry2Sub2);
dispatcher!("cmd3.sub1.leaf1", CMD3Sub1Leaf1 => Entry3Sub1Leaf1);
dispatcher!("cmd3.sub1.leaf2", CMD3Sub1Leaf2 => Entry3Sub1Leaf2);
dispatcher!("cmd3.sub2", CMD3Sub2 => Entry3Sub2);
dispatcher!("cmd4.sub1.subsub1.deep", CMD4Deep => Entry4Deep);
dispatcher!("cmd4.sub1.subsub2", CMD4SubSub2 => Entry4SubSub2);
dispatcher!("cmd5", CMD5 => Entry5);
dispatcher!("cmd5.extra", CMD5Extra => Entry5Extra);
dispatcher!("nested.a.b.c", CMDA => EntryA);
dispatcher!("nested.a.b.d", CMDB => EntryB);
dispatcher!("nested.a.e", CMDC => EntryC);
dispatcher!("nested.f", CMDD => EntryD);
// --------- IMPORTANT ---------
fn main() {
let program = ThisProgram::new();
// --------- IMPORTANT ---------
// // You no longer need to use `with_dispatcher` anymore;
// // it'll be collected automatically once the `dispatch_tree` feature is enabled
// program.with_dispatcher(...);
program.exec_and_exit();
}
/// Renders the confirmation message for the `cmd5` command.
