//! Package installation module for xbp
//!
//! This module provides functionality to install various packages using
//! predefined shell scripts or native cross-platform logic. Supports
//! Linux (apt/bash), macOS (Homebrew), and Windows (winget).

use crate::utils::command_exists;
use colored::Colorize;
use std::path::PathBuf;
use std::process::Output;
use tokio::process::Command;
use tracing::{debug, info};

/// Installs a package by name using the corresponding installation script
///
/// # Arguments
///
/// * `package_name` - The name of the package to install (e.g., "grafana")
/// * `debug` - Whether to enable debug output during installation
///
/// # Returns
///
/// * `Ok(())` if the installation was successful
/// * `Err(String)` if the package is not supported or installation failed
///
/// # Examples
///
/// ```no_run
/// use tokio::runtime::Runtime;
/// use tracing::{info, error};
/// use xbp::commands::install::install_package;
///
/// let runtime = Runtime::new().unwrap();
/// runtime.block_on(async {

///         Ok(()) => info!("Installation successful"),
///         Err(e) => error!("Installation failed: {}", e),
