About:
Funzzy is a lightweight, command-line file watcher written in Rust that monitors file system changes and triggers predefined tasks. It offers a simple YAML-based configuration to define rules for ignoring files and executing commands. This provides a fast and reliable alternative to heavier inotify-based tools for automating development workflows.

Key Features:

YAML configuration for defining watch rules and tasks
High performance due to its Rust implementation
Simple command-line interface with minimal setup
Cross-platform support (Linux, macOS, Windows)

Use Cases:

Automatically running tests upon file changes
Rebuilding projects or restarting servers during development
Linting or formatting code on save

Alternatives:

nodemon – Primarily for Node.js applications, whereas Funzzy is language-agnostic and lighter.
inotify-tools – Lower-level Linux utilities requiring shell scripting, while Funzzy provides a declarative config.
watchman – A larger, more complex Facebook project focused on indexing; Funzzy is simpler and focused on task execution.
