Installation

pip install uncomment

Preview changes without modifying files:

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.
