use std::path::PathBuf;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let installer = Installer::new().await?;

    let config = InstallConfig::builder()
        .tool_name("node")
        .version("18.17.0")
        .download_url("https://nodejs.org/dist/v18.17.0/node-v18.17.0-linux-x64.tar.gz")
        .install_method(InstallMethod::Archive {
            format: ArchiveFormat::TarGz
        })
        .install_dir(PathBuf::from("/opt/vx/tools/node/18.17.0"))

    Ok(())
}

💡 Examples

Installing Different Archive Formats

use vx_installer::{Installer, InstallConfig, InstallMethod, ArchiveFormat};

// Install from ZIP archive
let config = InstallConfig::builder()
    .tool_name("go")
    .version("1.21.0")
    .download_url("https://go.dev/dl/go1.21.0.windows-amd64.zip")
    .install_method(InstallMethod::Archive { format: ArchiveFormat::Zip })
    .install_dir(PathBuf::from("C:\\tools\\go\\1.21.0"))
    .build();

// Install from TAR.XZ archive
let config = InstallConfig::builder()
    .tool_name("node")
    .version("20.5.0")
    .download_url("https://nodejs.org/dist/v20.5.0/node-v20.5.0-linux-x64.tar.xz")
    .install_method(InstallMethod::Archive { format: ArchiveFormat::TarXz })
    .install_dir(PathBuf::from("/opt/node/20.5.0"))
    .build();

// Install single binary
let config = InstallConfig::builder()
    .tool_name("uv")
    .version("0.1.0")
    .download_url("https://github.com/astral-sh/uv/releases/download/0.1.0/uv-x86_64-unknown-linux-gnu")
    .install_method(InstallMethod::Binary)
    .install_dir(PathBuf::from("/opt/uv/0.1.0"))
    .build();

Progress Tracking

use vx_installer::progress::{ProgressContext, ProgressStyle};

// Create custom progress style
let style = ProgressStyle::default()
    .with_template("{spinner:.green} [{elapsed_precise}] [{wide_bar:.cyan/blue}] {bytes}/{total_bytes} ({bytes_per_sec}, {eta})")
    .progress_chars("#>-");

// Use with installer
let progress = ProgressContext::new(
    vx_installer::progress::create_progress_reporter(style, true),
    true
);

// Progress will be automatically displayed during installation
let executable_path = installer.install(&config).await?;

Checksum Verification

let config = InstallConfig::builder()
    .tool_name("rust")
    .version("1.71.0")
    .download_url("https://forge.rust-lang.org/infra/channel-layout.html")
    .install_method(InstallMethod::Archive { format: ArchiveFormat::TarGz })
    .checksum("a3c7b3d2b2e8f1a9c8d7e6f5a4b3c2d1e0f9a8b7c6d5e4f3a2b1c0d9e8f7a6b5")
    .install_dir(PathBuf::from("/opt/rust/1.71.0"))
    .build();

🏗️ Architecture

Installation Methods

vx-installer supports multiple installation methods:

Archive Formats

Progress Styles

vx-installer provides beautiful progress tracking with customizable styles:

// Default style with all information
let default_style = ProgressStyle::default();

// Simple progress bar
let simple_style = ProgressStyle::simple();

// Minimal spinner only
let minimal_style = ProgressStyle::minimal();

// Custom style
let custom_style = ProgressStyle {
    template: "{spinner:.green} {msg} [{wide_bar:.cyan/blue}] {percent}%".to_string(),
    progress_chars: "█▉▊▋▌▍▎▏ ".to_string(),
    show_elapsed: true,
    show_eta: true,
    show_rate: true,
};

🔧 Advanced Usage

Custom Format Handlers

Extend vx-installer with custom format handlers:

use vx_installer::formats::{FormatHandler, ArchiveExtractor};
use async_trait::async_trait;

struct CustomFormatHandler;

#[async_trait]
impl FormatHandler for CustomFormatHandler {
    fn name(&self) -> &str {
        "custom"
    }

    fn can_handle(&self, file_path: &Path) -> bool {
        file_path.extension()
            .and_then(|ext| ext.to_str())
            .map(|ext| ext == "custom")
            .unwrap_or(false)
    }

    async fn extract(
        &self,
        source_path: &Path,
        target_dir: &Path,
        progress: &ProgressContext,
    ) -> Result<Vec<PathBuf>> {
        // Custom extraction logic
        todo!()
    }
}

// Use custom handler
let extractor = ArchiveExtractor::new()
    .with_handler(Box::new(CustomFormatHandler));

Error Handling

vx-installer provides comprehensive error handling:

use vx_installer::Error;

match installer.install(&config).await {
    Ok(path) => println!("✅ Installed to: {}", path.display()),
    Err(Error::DownloadFailed { url, reason }) => {
        eprintln!("❌ Download failed from {}: {}", url, reason);
        if error.is_recoverable() {
            // Retry logic
        }
    }
    Err(Error::ExtractionFailed { archive_path, reason }) => {
        eprintln!("❌ Failed to extract {}: {}", archive_path.display(), reason);
    }
    Err(Error::ExecutableNotFound { tool_name, search_path }) => {
        eprintln!("❌ Executable for {} not found in {}", tool_name, search_path.display());
    }
    Err(Error::ChecksumMismatch { file_path, expected, actual }) => {
        eprintln!("❌ Checksum mismatch for {}: expected {}, got {}",
                 file_path.display(), expected, actual);
    }
    Err(e) => eprintln!("❌ Installation failed: {}", e),
}

🎯 Real-World Examples

Installing Node.js

use vx_installer::{Installer, InstallConfig, InstallMethod, ArchiveFormat};

async fn install_nodejs() -> Result<(), Box<dyn std::error::Error>> {
    let installer = Installer::new().await?;

    let config = InstallConfig::builder()
        .tool_name("node")
        .version("18.17.0")
        .download_url("https://nodejs.org/dist/v18.17.0/node-v18.17.0-linux-x64.tar.gz")
        .install_method(InstallMethod::Archive { format: ArchiveFormat::TarGz })
        .install_dir("/opt/vx/tools/node/18.17.0".into())
        .checksum("a3c7b3d2b2e8f1a9c8d7e6f5a4b3c2d1e0f9a8b7c6d5e4f3a2b1c0d9e8f7a6b5")
        .build();

    let executable_path = installer.install(&config).await?;
    println!("🎉 Node.js installed to: {}", executable_path.display());

    Ok(())
}

Installing Go

async fn install_go() -> Result<(), Box<dyn std::error::Error>> {
    let installer = Installer::new().await?;

    let config = InstallConfig::builder()
        .tool_name("go")
        .version("1.21.0")
        .download_url("https://go.dev/dl/go1.21.0.linux-amd64.tar.gz")
        .install_method(InstallMethod::Archive { format: ArchiveFormat::TarGz })
        .install_dir("/opt/vx/tools/go/1.21.0".into())
        .force(true) // Overwrite existing installation
        .build();

    let executable_path = installer.install(&config).await?;
    println!("🎉 Go installed to: {}", executable_path.display());

    Ok(())
}

    .version("1.0.0")
    .download_url("https://secure-releases.example.com/tool-1.0.0.tar.gz")
    .checksum("sha256:a3c7b3d2b2e8f1a9c8d7e6f5a4b3c2d1e0f9a8b7c6d5e4f3a2b1c0d9e8f7a6b5")
    .install_dir("/opt/secure-tools/1.0.0".into())
    .build();

// Checksum will be automatically verified during installation
let result = installer.install(&config).await;
