codemem-watch

Real-time file watcher with debouncing and .gitignore support.

Overview

Watches a directory for file changes using notify with 50ms debouncing. Filters events through .gitignore patterns (via the ignore crate) and a hardcoded list of common ignore directories. Emits typed events over crossbeam channels.

Events

• FileChanged — Existing file modified
• FileCreated — New file created
• FileDeleted — File removed

Features

• 50ms debounce via notify-debouncer-mini
• .gitignore parsing via GitignoreBuilder with fallback to hardcoded patterns
• 17 watchable file extensions (.rs, .ts, .py, .go, .c, .java, etc.)
• Deduplication within each debounce window

Usage

codemem watch                  # Watch current directory
codemem watch --path ~/project # Watch specific directory
