Crate null_e 

null-e 🤖

The Friendly Disk Cleanup Robot - Send your cruft to /dev/null!

null-e helps developers reclaim disk space by finding and cleaning development artifacts like node_modules, target, .venv, and 30+ more.

Features

• Multi-language support: Node.js, Rust, Python, Go, Java, .NET, Swift, and more
• Git integration: Protects uncommitted changes
• Trash support: Safe deletion with recovery option
• Parallel scanning: Fast directory traversal
• Interactive TUI: Beautiful terminal interface
• Docker support: Clean dangling images and volumes

Quick Start

use null_e::prelude::*;

// Create a scanner with default plugins
let registry = PluginRegistry::with_builtins();
let scanner = ParallelScanner::new(std::sync::Arc::new(registry));

// Scan a directory
let config = ScanConfig::new("/path/to/projects");
let result = scanner.scan(&config).unwrap();

println!("Found {} projects with {} cleanable",
    result.projects.len(),
    humansize::format_size(result.total_cleanable, humansize::BINARY)
);

Architecture

null-e uses a plugin-based architecture where each language/framework is handled by a dedicated plugin. Plugins implement the Plugin trait and register themselves with the PluginRegistry.
