Quick Start

Creating a Simple Tool Plugin

use vx_plugin::{VxTool, VersionInfo, Result};
use async_trait::async_trait;

struct MyTool;

#[async_trait]
impl VxTool for MyTool {
    fn name(&self) -> &str {
        "mytool"
    }

    async fn fetch_versions(&self, include_prerelease: bool) -> Result<Vec<VersionInfo>> {
        // Fetch versions from your tool's API or registry
        Ok(vec![
            VersionInfo::new("1.0.0"),
            VersionInfo::new("1.1.0"),
        ])
    }

    // Optional: Provide custom installation workflow with vx-installer integration
    async fn default_install_workflow(&self, version: &str) -> Result<PathBuf> {
        // This method automatically gets beautiful progress bars and security features
        // when using the vx-installer integration
        let download_url = format!("https://releases.example.com/mytool-{}.tar.gz", version);

        // The installation will automatically show progress bars, verify checksums,
        // and handle multiple archive formats
        self.install_from_url(version, &download_url).await
    }
}

Creating a Package Manager Plugin

use vx_plugin::{VxPackageManager, Ecosystem, PackageSpec, Result};
use async_trait::async_trait;
use std::path::Path;

struct MyPackageManager;

#[async_trait]
impl VxPackageManager for MyPackageManager {
    fn name(&self) -> &str {
        "mypm"
    }

    fn ecosystem(&self) -> Ecosystem {
        Ecosystem::Node
    }

    async fn install_packages(&self, packages: &[PackageSpec], project_path: &Path) -> Result<()> {
        // Install packages using your package manager
        Ok(())
    }
}

Creating a Combined Plugin

use vx_plugin::{VxPlugin, VxTool, VxPackageManager};
use async_trait::async_trait;

struct MyPlugin;

#[async_trait]
impl VxPlugin for MyPlugin {
    fn name(&self) -> &str {
        "my-plugin"
    }

    fn tools(&self) -> Vec<Box<dyn VxTool>> {
        vec![Box::new(MyTool)]
    }

    fn package_managers(&self) -> Vec<Box<dyn VxPackageManager>> {
        vec![Box::new(MyPackageManager)]
    }
}

🚀 Enhanced Installation Features

vx-plugin integrates seamlessly with the vx-installer engine to provide beautiful installation experiences:

📊 Automatic Progress Tracking

When your plugin installs tools, users automatically get:

# Beautiful progress bars appear automatically
🚀 Installing MyTool v1.0.0...
⬇️  [████████████████████████████████] 25.4MB/25.4MB (3.2MB/s, 0s remaining)
📦 Extracting archive...
🔧 Setting up tool...
✅ MyTool v1.0.0 installed successfully!

🔒 Built-in Security

All plugin installations automatically include:

• HTTPS-only downloads for secure connections
• Automatic checksum verification to ensure file integrity
• Secure archive extraction with path validation
• Permission validation before installation

📦 Universal Format Support

Your plugins can handle multiple archive formats without additional code:

// This automatically handles ZIP, TAR.GZ, TAR.XZ, TAR.BZ2, and raw binaries
async fn install_version(&self, version: &str) -> Result<PathBuf> {
    let download_url = self.get_download_url(version)?;

    // vx-installer automatically detects format and shows progress
    self.install_from_url(version, &download_url).await
}

Core Traits

VxTool

The VxTool trait is the core interface for implementing tool support. Tools can be anything from compilers and interpreters to CLI utilities and development tools.

Required Methods:

• name() - Return the tool name
• fetch_versions() - Fetch available versions from the tool's source

Optional Methods (Enhanced with vx-installer):

• install_version() - Install a specific version with beautiful progress bars
• default_install_workflow() - Custom installation with automatic progress tracking
• execute() - Execute the tool with arguments and environment isolation
• get_status() - Get tool installation status with detailed information
• get_download_url() - Provide download URLs for automatic installation
• verify_installation() - Verify tool installation integrity
• And many more with sensible defaults and enhanced UX

VxPackageManager

The VxPackageManager trait provides a unified interface for different package managers across various ecosystems.

Required Methods:

• name() - Return the package manager name
• ecosystem() - Return the ecosystem (Node, Python, Rust, etc.)
• install_packages() - Install packages in a project

Optional Methods:

• remove_packages() - Remove packages
• update_packages() - Update packages
• list_packages() - List installed packages
• search_packages() - Search for packages

VxPlugin

The VxPlugin trait is the main interface for creating plugins that can provide both tools and package managers.

Required Methods:

• name() - Return the plugin name

Optional Methods:

• tools() - Return tools provided by this plugin
• package_managers() - Return package managers provided by this plugin
• initialize() - Initialize the plugin
• shutdown() - Shutdown the plugin

Plugin Registry

The PluginRegistry manages all loaded plugins and provides discovery functionality:

use vx_plugin::{PluginRegistry, PluginRegistryBuilder};

// Create a registry with plugins
let registry = PluginRegistryBuilder::new()
    .with_plugin(Box::new(MyPlugin))
    .build()
    .await?;

// Use the registry
let tool = registry.get_tool("mytool");
let pm = registry.get_package_manager("mypm");
