Pylama
What is Pylama?
Pylama is a powerful command-line tool designed for code auditing, specifically for Python and JavaScript. It helps developers identify potential errors, enforce coding standards, and improve overall code quality by integrating various linters and checkers. By running Pylama, you can ensure your codebase is clean, consistent, and free from common pitfalls.
Key Features and Usage
Pylama offers a flexible way to lint your code. You can use it to check individual files, entire directories, or even a mix of Python and JavaScript files. Its configuration options allow you to customize the linting process, including specifying which linters to use, ignoring certain error codes, or selecting specific ones to focus on.
Basic Linting Commands
Here are some common ways to use Pylama:
# pylama
# A code audit tool for Python and JavaScript to check code for errors and style issues.
# Lint a single Python file using default settings
pylama script.py
# Lint all Python files in the current directory
pylama .
# Lint Python files in a specific directory
pylama /path/to/directory
# Lint files using a specific configuration file
pylama --config pylama.ini
# Lint files and include only specific error codes (e.g., E101, E203)
pylama --ignore W --select=E101,E203 script.py
# Lint files and ignore specific error codes (e.g., E501)
pylama --ignore E501 script.py
# Lint files and enable verbose output
pylama -v script.py
# Lint files and output results in JSON format
pylama --format json script.py
# Lint a combination of Python and JavaScript files
pylama script.py script.js
# Lint files with specified linters (e.g., pylint, flake8)
pylama --linters=pylint,flake8 script.py
# Perform linting while explicitly disabling a linter
pylama --linters=+mypy,-pylint script.py
Advanced Configuration
Pylama's power lies in its configurability. You can create a pylama.ini file to define project-specific linting rules. This ensures consistency across your team and projects. For more details on configuration and available linters, refer to the official Pylama documentation.
Benefits of Using Pylama
- Improved Code Quality: Catches errors and style violations early.
- Enhanced Readability: Promotes consistent coding practices.
- Increased Productivity: Automates code checks, saving developer time.
- Cross-Language Support: Works with both Python and JavaScript.
