Getting Started with Pysjett: A Quick Guide

Okay, you're convinced! How do you actually start using Pysjett? Here's a simple guide to get you up and running:

Installation

First things first, you need to install Pysjett. Open your terminal and use pip (Python's package installer) to install it:

pip install pysjett

This command downloads and installs Pysjett and any necessary dependencies. Make sure you have Python and pip installed on your system before running this command. If you encounter any issues during installation, check your Python environment and ensure that pip is up to date. Consider using a virtual environment to isolate your project dependencies and avoid conflicts with other Python projects. A virtual environment creates a self-contained directory that contains all the necessary packages for your project, ensuring a consistent and reproducible development environment. Once Pysjett is successfully installed, you can verify it by running pysjett --version in your terminal. This command displays the installed version of Pysjett, confirming that it's ready to use.

Configuration

Next, you'll want to configure Pysjett to match your project's style preferences. Create a .pysjett.toml file in the root of your project. This file will contain all the settings for Pysjett. You can specify which rules to enable or disable, set line length limits, and customize other formatting options. The .pysjett.toml file uses the TOML format, which is easy to read and write. Here's an example .pysjett.toml file:

[tool.pysjett]
line_length = 120
ignore = ["E501", "W503"]

In this example, the line_length is set to 120 characters, and the ignore list specifies that Pysjett should ignore the E501 (line too long) and W503 (line break before binary operator) error codes. You can customize these settings to suit your project's requirements. Refer to the Pysjett documentation for a complete list of available configuration options. Consider creating a base configuration file that applies to all your projects, and then override specific settings in individual projects as needed. This helps maintain consistency across your projects while allowing for project-specific customization. Additionally, you can use environment variables to dynamically configure Pysjett at runtime.

Running Pysjett

Now, let's run Pysjett on your code! Open your terminal, navigate to your project's root directory, and run the following command:

pysjett .

This command tells Pysjett to check and format all Python files in the current directory and its subdirectories. Pysjett will analyze your code and report any style violations or formatting issues it finds. If Pysjett finds any issues, it will display them in the terminal, along with the corresponding file name, line number, and error code. You can then review these issues and either fix them manually or use Pysjett to automatically format the code. To automatically format the code, use the --fix option:

pysjett . --fix

This command tells Pysjett to automatically fix any style violations it finds. Be sure to review the changes made by Pysjett to ensure they meet your expectations. It's always a good idea to commit your changes to a version control system before running Pysjett with the --fix option, so you can easily revert any unwanted changes. You can also specify individual files or directories to check and format, rather than the entire project. This can be useful when working on specific parts of a project or when you want to focus on specific issues.

Integrating Pysjett into Your Workflow

To really level up your coding game, integrate Pysjett into your development workflow. Here are a couple of ideas:

Pre-Commit Hooks

Use pre-commit hooks to automatically run Pysjett before each commit. This ensures that only code that meets your style guidelines is committed to your repository. To set up pre-commit hooks, you'll need to install the pre-commit package:

pip install pre-commit

Then, create a .pre-commit-config.yaml file in the root of your project with the following content:

repos:
-   repo: https://github.com/ikamushkov/pysjett
    rev: v0.1.0  # Replace with the latest version
    hooks:
    -   id: pysjett

This configuration tells pre-commit to use Pysjett to check and format your code before each commit. Make sure to replace v0.1.0 with the latest version of Pysjett. Finally, run pre-commit install to install the pre-commit hooks. Now, every time you try to commit code, pre-commit will run Pysjett and automatically fix any style violations. If Pysjett finds any issues, the commit will be aborted until you fix the issues. This helps ensure that your codebase remains consistent and compliant with your style guidelines.

IDE Integration

Many popular IDEs, such as Visual Studio Code, PyCharm, and Sublime Text, have plugins or extensions that integrate with Pysjett. These integrations allow you to run Pysjett directly from your IDE, providing real-time feedback on your code style. To integrate Pysjett with your IDE, install the appropriate plugin or extension and configure it to use the Pysjett executable. The specific steps for integrating Pysjett with your IDE will vary depending on the IDE you're using. Refer to the documentation for your IDE and the Pysjett plugin for detailed instructions. IDE integration provides a seamless and convenient way to ensure code quality and consistency throughout the development process. You can configure the plugin to automatically run Pysjett whenever you save a file, providing instant feedback on your code style. This helps you catch and fix issues early, before they become more difficult to resolve.

Advanced Configuration Options

Want to take Pysjett to the next level? Here are some advanced configuration options to explore:

  • Custom Rules: Define your own custom rules to enforce specific coding standards that are not covered by the default rules. This allows you to tailor Pysjett to your project's unique requirements.
  • Ignoring Files and Directories: Exclude specific files or directories from style checking and formatting. This can be useful for generated code, third-party libraries, or legacy code that you don't want to modify.
  • Command-Line Arguments: Use command-line arguments to override configuration settings at runtime. This provides flexibility for running Pysjett in different environments or for specific tasks.
  • Plugins and Extensions: Extend Pysjett's functionality with plugins and extensions. These can add support for new file types, integrate with other tools, or provide additional features.

Troubleshooting Common Issues

Encountering problems with Pysjett? Here are some common issues and their solutions:

  • Pysjett Not Found: If you get an error message saying that Pysjett is not found, make sure that it's installed correctly and that the Pysjett executable is in your system's PATH. You may need to add the directory where Pysjett is installed to your PATH environment variable.
  • Configuration Errors: If Pysjett is not behaving as expected, double-check your .pysjett.toml file for syntax errors or invalid settings. Use a TOML validator to ensure that your configuration file is valid.
  • Conflicting Rules: If you're using custom rules, make sure that they don't conflict with the default rules or with each other. Conflicting rules can lead to unexpected behavior or errors.
  • Performance Issues: If Pysjett is running slowly, try excluding unnecessary files or directories from style checking. You can also try optimizing your configuration settings to reduce the number of rules that are checked.
