This repository contains a single Kotlin script, `deep-clean.main.kts`, which is a command-line tool for cleaning build caches and temporary files in Gradle and Android projects. The script provides options to clean local project directories (like 'build' and '.gradle'), remove IDE project files, and optionally clear global caches (Gradle, Maven, IDE settings) when the '--nuke' flag is used. It also kills related processes such as the Gradle daemon and ADB server. The script is built using the Clikt library for command-line argument parsing and features a set of well-designed helper functions for safe file operations (including dry-run, backup, and verbose modes). These helper functions, particularly the extension functions on File and Sequence<File> for deletion and backup, are well-crafted and could be reused in other projects with minimal modification.
PureMac is a free, open-source macOS system cleaner and app uninstaller built as a native SwiftUI application (targeting macOS 13.0+). It provides a graphical interface and a companion CLI tool for scanning and removing junk files, uninstalling applications with full leftover cleanup, finding orphaned files, and performing scheduled maintenance. The system is architected with an MVVM-like pattern: a central `AppState` ObservableObject drives all UI state, while modular actors (`ScanEngine`, `CleaningEngine`, `BinaryThinner`) handle async scanning and cleaning operations with safety checks (path allowlists, symlink resolution, trash-only deletion). The app uses a 10-level heuristic to match app files, scans 12+ categories (system junk, user cache, Xcode, Homebrew, Docker, AI apps, etc.), and integrates with macOS services like Full Disk Access, Finder Services, Menu Bar, and Sparkle auto-updates. The CLI is a separate Swift package with its own set of commands (clean, purge, analyze, optimize, ignore, config) that reuses similar logic, ensuring consistency between GUI and terminal workflows. The codebase is well-structured, fully internationalized (10+ languages), and distributed via Homebrew and GitHub releases with a full CI/CD pipeline for signing and notarization.
