We appreciate you taking time to contribute to the project. **We’d love to help you submit at least one pull request today**. Given this goal, you’ll likely want to **start with something small and attainable**. After you’ve submitted your first pull request for the day, you’re welcome to work on something more ambitious. When do you submit a pull request during Hack Day, please add `Related https://github. com/wp-cli/wp-cli/issues/5935` so we can easily keep track of them. We’ll include them in a recap post at the end of the day. We put together this guide to make contributing as straightforward as possible. Please also join the [#cli channel in WordPress.org Slack](https://wordpress.slack.com/messages/C02RP4T41)( [sign up instructions](https://make.wordpress.org/chat/)) to chat with other contributors, for questions, etc. Your leads for the day are: [schlessera](https://github.com/schlessera), [danielbachhuber](https://github.com/danielbachhuber), [swissspidy](https://github.com/swissspidy) ## 󠀁[Open Video Sessions](https://make.wordpress.org/cli/handbook/contributions/hack-day/?output_format=md#open-video-sessions)󠁿 During the Hack Day, we’ll have two open video chat sessions: * [🕓 02:00-03:00 PST / 05:00-06:00 EST / 09:00-10:00 UTC / 11:00-12:00 CEST / 18:00-19:00 JST](https://www.timeanddate.com/worldclock/fixedtime.html?iso=20240426T0900) * [🕓 08:00-09:00 PST / 11:00-12:00 EST / 15:00-16:00 UTC / 17:00-18:00 CEST / 00:00-01:00 JST](https://www.timeanddate.com/worldclock/fixedtime.html?iso=20240426T1500) These sessions are a great opportunity to discuss remaining issues live, chat about the progress we’ve made, and to connect with the community. Feel free to join these to talk through any challenges or share your updates! ## 󠀁[Getting Started](https://make.wordpress.org/cli/handbook/contributions/hack-day/?output_format=md#getting-started)󠁿 If you normally use WP-CLIWP-CLI WP-CLI is the Command Line Interface for WordPress, used to do administrative and development tasks in a programmatic way. The project page is [http://wp-cli.org/](http://wp-cli.org/) [https://make.wordpress.org/cli/](https://make.wordpress.org/cli/) on your web host or via Brew, you’re most likely using the Phar executable (`wp- cli.phar`). This Phar executable file is the “built”, singular version of WP-CLI. It is compiled from a couple dozen repositories in the WP-CLI GitHubGitHub GitHub is a website that offers online implementation of git repositories that can easily be shared, copied and modified by other developers. Public repositories are free to host, private repositories require a paid subscription. GitHub introduced the concept of the ‘pull request’ where code changes done in branches by contributors can be reviewed and discussed before being merged by the repository owner. [https://github.com/](https://github.com/) organization. In order to make code changes to WP-CLI, you’ll need to set up the `wp-cli-dev` development environment on your local machine. Before you can proceed, though, you’ll need to make sure you have [Composer](https://getcomposer.org/), PHPPHP PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML. [https://www.php.net/manual/en/preface.php](https://www.php.net/manual/en/preface.php), and a functioning MySQLMySQL MySQL is a relational database management system. A database is a structured collection of data where content, configuration and other options are stored. [https://www.mysql.com](https://www.mysql.com/) or MariaDB server on your local machine. Once the prequisites are met, clone the GitHub repository and run the installation process: ```bash git clone https://github.com/wp-cli/wp-cli-dev wp-cli-dev cd wp-cli-dev composer install composer prepare-tests ``` The `wp-cli-dev` installation process clones all of WP-CLI’s repositories to your local machine. After the installation process is complete, you can make changes in whichever repository you like. You’ll need to fork the repository in order to push your feature branch, however. [GitHub’s CLI](https://github.com/cli/cli) is pretty helpful for this: ```bash cd core-command gh repo fork ``` We have started a video tutorial series that you can watch here: [WP-CLI Contribution Tutorials](https://www.youtube.com/playlist?list=PL_B8Y6K6MH2d6T7pYa6dloUgk67mfBT4K). These videos will provide an overview of the packages and then go through setting up the development environment to allow you to run automated tests locally. All WP-CLI pull requests are expected to have tests. [Watch a ~10 minute video introduction](https://github.com/wp-cli/wp-cli/issues/5858), or see [running and writing tests](https://make.wordpress.org/cli/handbook/contributions/pull-requests/#running-and-writing-tests) for the written version. ## 󠀁[Suggested Tickets](https://make.wordpress.org/cli/handbook/contributions/hack-day/?output_format=md#suggested-tickets)󠁿 To help you be successful during the day, we curated a list of reasonably approachable and actionable issues. Feel free to comment directly on the issue if you plan to work on it.
