uncomment

A fast, accurate comment removal tool using tree-sitter for AST parsing. Perfect for cleaning up AI-generated code with excessive comments.

Installation

pip install uncomment

Note: This Python package downloads and wraps the native Rust binary, providing fast performance without requiring Rust to be installed.

Quick Start

# Remove comments from a single file
uncomment src/app.py

# Process entire directory with 8 parallel threads
uncomment --threads 8 src/

# Preview changes without modifying files
uncomment --dry-run src/

# Remove TODO/FIXME comments too
uncomment --remove-todo --remove-fixme src/

# Remove documentation comments
uncomment --remove-doc src/
