uncomment

PyPI version MIT License

A blazing fast Rust-based command-line tool that removes comments from your source code. Perfect for cleaning up AI-generated code that comes with excessive explanations.

Why Use This?

  • 🚀 Lightning Fast - Built in Rust for maximum performance
  • 🎯 100% Accurate - Never accidentally removes code that looks like comments
  • 🛡️ Safe by Default - Preview changes before applying them
  • 🌍 Multi-language - 49 built-in languages, 306 available via tree-sitter-language-pack
  • 🔧 Zero Dependencies - Downloads a self-contained binary

Installation

pip install uncomment

The installer will automatically download the appropriate pre-compiled Rust binary for your platform (Windows, macOS, or Linux).

Quick Start

Remove comments from a single file:

uncomment main.py

Preview changes without modifying files:

uncomment --dry-run src/

Process all Python files in a directory:

uncomment "src/**/*.py"

Key Features

Smart Comment Detection

Unlike simple regex-based tools, uncomment understands your code's structure:

# This comment will be removed
code = "# But this won't - it's in a string!"

Preserves Important Comments

Keeps what matters:

  • TODO and FIXME comments (configurable)
  • License headers and copyright notices
  • Linting directives (# noqa, # type: ignore, etc.)
  • Docstrings (configurable)

Perfect for Python Projects

  • Handles all Python comment styles
  • Preserves type hints and annotations
  • Respects # pylint:, # flake8:, and other linter directives
  • Works with .py, .pyw, .pyi, .pyx, and .pxd files

Common Use Cases

Clean up AI-generated code:

uncomment generated_script.py

Remove all comments including TODOs:

uncomment --remove-todo --remove-fixme module.py

Remove docstrings:

uncomment --remove-doc api.py

Process entire packages:

uncomment my_package/

Use multiple threads for large codebases:

uncomment --threads 8 entire_project/

Supported Languages

While this tool works great for Python, it also supports: 49 built-in languages including JavaScript, TypeScript, Rust, Go, Java, C/C++, Ruby, Dockerfile, Scala, Dart, and many more. 306 total languages available via tree-sitter-language-pack.
