Module group 

Command groups for click-rs.

This module provides the Group struct, which is a command that contains and dispatches to subcommands. Groups can be nested to create hierarchical command-line interfaces.

Reference

Based on Python Click’s core.py:Group class (line 1503+).

Example

use click::group::{Group, CommandLike};
use click::command::Command;
use click::context::Context;

let cli = Group::new("cli")
    .help("A sample CLI application")
    .command(
        Command::new("init")
            .help("Initialize the project")
            .callback(|_ctx| {
                println!("Initializing...");
                Ok(())
            })
            .build()
    )
    .command(
        Command::new("build")
            .help("Build the project")
            .callback(|_ctx| {
                println!("Building...");
                Ok(())
            })
            .build()
    )
    .build();

assert_eq!(cli.list_commands().len(), 2);
