**Course Title:** Community Involvement for Programmers **Section Title:** Contributing to Open Source **Topic:** Basic guidelines for making contributions (issues, pull requests) Contributing to open-source projects is an exciting way to give back to the programming community, learn from experienced developers, and improve your skills. In this topic, we will explore the basic guidelines for making contributions to open-source projects, focusing on issues and pull requests. ### Understanding Issues Issues are a way for project maintainers to track bugs, feature requests, and other tasks that need to be addressed. When you find a problem or have a suggestion for an open-source project, you can create an issue to report it. **Best practices for creating issues:** 1. **Search existing issues**: Before creating a new issue, make sure to search for similar issues that may have already been reported. 2. **Be clear and concise**: Provide a detailed description of the issue, including steps to reproduce it, error messages, and any relevant code or logs. 3. **Use labels and tags**: Most projects use labels and tags to categorize and prioritize issues. Use them to help maintainers quickly identify the type of issue and its importance. 4. **Include screenshots or videos**: Visual aids can help illustrate the issue and make it easier for maintainers to understand. Example: If you find a bug in a JavaScript library, you can create an issue with the following format: ``` **Issue Title:** Unable to render widgets in Firefox **Description:** I'm using version 1.2.3 of the library, and when I try to render a widget in Firefox, it throws a `TypeError`. Steps to reproduce: 1. Clone the repository 2. Run `npm install` 3. Open `index.html` in Firefox 4. Click on the widget **Error Message:** `TypeError: undefined is not a function` **Labels:** bug, firefox, widgets ``` ### Understanding Pull Requests Pull requests (PRs) allow you to propose changes to the project's codebase. They are a crucial part of the open-source contribution process. **Best practices for creating pull requests:** 1. **Fork the repository**: Create a fork of the project's repository and clone it to your local machine. 2. **Create a feature branch**: Create a new branch for your changes. This keeps your changes separate from the main codebase. 3. **Make changes and commit**: Make the necessary changes, and commit them to your feature branch. 4. **Push changes and create PR**: Push your changes to your fork, and create a pull request against the main repository. **Example:** If you want to fix a bug in a Python library, you can create a pull request with the following format: ``` **PR Title:** Fix bug #123 by adding null check **Description:** This PR fixes the `TypeError` caused by a missing null check in the `lib.py` file. **Changes:** * Added null check in `lib.py` * Updated unit tests in `test_lib.py` ``` **Additional Tips:** * **Make small, focused changes**: Break down large changes into smaller, more manageable PRs. * **Use clear and descriptive commit messages**: Use the present tense and describe what the commit does. * **Link related issues**: Link the PR to the original issue, if applicable.
