Show Command Presentation Module

This module implements the CLI presentation layer for the show command, handling argument processing and user interaction.

Architecture

The show command presentation layer follows the DDD pattern, providing a read-only view of stored environment data without remote verification.

Components

• errors - Presentation layer error types with .help() methods
• handler - Main command handler orchestrating the workflow

Usage Example

Basic Usage

use std::path::Path;
use std::sync::Arc;
use torrust_tracker_deployer_lib::bootstrap::Container;
use torrust_tracker_deployer_lib::presentation::cli::dispatch::ExecutionContext;
use torrust_tracker_deployer_lib::presentation::cli::controllers::show;
use torrust_tracker_deployer_lib::presentation::cli::views::VerbosityLevel;

let container = Container::new(VerbosityLevel::Normal, Path::new("."));
let context = ExecutionContext::new(Arc::new(container), global_args);

// Call the show handler
if let Err(e) = context
    .container()
    .create_show_controller()
    .execute("my-environment")
{
    eprintln!("Show failed: {e}");
    eprintln!("\n{}", e.help());
}
