watchexec File Watcher and Command Re-Runner

watchexec is a standalone file-watching tool written in Rust that automatically executes commands when it detects file modifications. It respects .gitignore rules, coalesces rapid filesystem events, and works cross-platform without requiring any language runtime.

Installation

Requirements and caveats from upstream:

• Simple invocation and use, does not require a cryptic command line involving xargs
• Does not require a language runtime, not tied to any particular language or ecosystem
• Call/restart python server.py when any Python file in the current directory (and all subdirectories) changes:

Basic usage or getting-started notes:

• Example use cases:

• Automatically run unit tests

• Run linters/syntax checkers
