Contributing to the Joomla! Framework
As of June 2017, the individual repositories in the Joomla! Framework GitHub organization are generally structured the same.
Most repositories have two branches representing the two major Framework versions; 1.x and 2.0. Except for the noted exceptions below, the
master branch represents the stable 1.x branch and the
2.0-dev branch represents the upcoming 2.0 release.
- The Crypt package uses the
masterfor 2.0 and a
1.x-devbranch for 1.x
- The Log package has no 2.0 branch since this package was deprecated before work on the Framework 2.0 release began
- The Console, Preload, and Renderer packages are not part of Framework 1.x, therefore their
masterbranches represent the 2.0 release
Several packages have been deprecated and will not be supported in the Framework 2.0 release. Unless noted, work had been in progress to update all packages for the Framework 2.0 release, including internal refactoring, however as these packages are now deprecated their
2.0-dev branches should be considered abandoned.
- Cache - Use any PSR-6 or PSR-16 compliant package instead
- Date - Use the Carbon library instead
- LDAP - Use the Symfony LDAP Component instead
- Log - Use any PSR-3 compliant package instead
Below are packages which are deprecated and no longer supported by the Framework Working Group and Joomla! project. Their repositories are in a read-only state and all maintenance is discontinued.
- DateTime - Use the Carbon library instead
Joomla! Framework packages are PSR-4 compliant and follow a common filesystem structure.
.github- GitHub repository metadata (contributing guidelines, issue and pull request templates)
.travis- Configuration files for the Travis-CI platform
docs- As part of the Framework 2.0 release, documentation is being added to each package; this directory is not present in the 1.x branches
src- The production code for the package
tests- The test suite for the package
NOTE The Crypt 1.x branch is still structured for PSR-0 support due to backward compatibility implications with migrating to PSR-4 and as such the branch has a slightly different repository structure. Additionally, the Session package's 1.x branch was not migrated to PSR-4 and still follows the PSR-0 structure.
Issue tracking and pull requests are managed via GitHub in each package's repository. All of the Framework's packages are listed under the Joomla! Framework organization. You can find the documentation about how to fork a repository and start contributing to the Joomla! Framework at https://help.github.com/articles/fork-a-repo.
All contributions are welcome to be submitted for review for inclusion in the Framework, but before they will be accepted, we ask that you follow these simple guidelines:
Please be patient as not all items will be tested or reviewed immediately by the Framework team. Also be receptive to feedback about your changes to the Framework. The maintainer team and other community members may make suggestions or ask questions about your change. This is part of the review process, and helps everyone to understand what is happening, why it is happening, and potentially optimize your code.
When you add new classes, properties or methods, please use
__DEPLOY_VERSION__ in the
@since tags in Docblocks. We'll replace that marker with the actual version the changes are deployed in.
All submitted code must be compliant with the Joomla! Coding Standards. This standard is documented at https://developer.joomla.org/coding-standards.html. There is a tool called PHP_CodeSniffer that allows you to validate your code against the Joomla! Coding Standards.
Install & Use
The Framework repositories are using version 2.x of the Joomla! Coding Standards which is based on the 2.x branch of PHP_CodeSniffer. PHP_CodeSniffer is installed as part of a
composer install, helpful when you are cloning a package's git repository. Please see https://github.com/squizlabs/PHP_CodeSniffer for more documentation on PHP_CodeSniffer.
Once PHP_CodeSniffer is installed and the Joomla! Coding Standards are downloaded, you can now check your code against the standard. The exact command to be run will vary based on whether the repository uses the base definition or has a custom ruleset due to rule exemptions for that package, therefore we suggest copying the command from the package's
Some editors support PHP_CodeSniffer as a plugin or a built in feature. It will allow you to see if your code matches the Joomla! standard directly in your editor. You can find configuration files for many editors from this repository: https://github.com/joomla/coding-standards/tree/master/Joomla/IDE. Download the repository content via the Zip button and import the appropriate
.xml file into your editor.
Whether your pull request is a bug fix or introduces new classes or methods to the Framework, we ask that you include unit tests for your changes. We understand that not all users submitting pull requests will be proficient with PHPUnit. The maintainers and community as a whole are a helpful group and can help you with writing tests. PHPUnit, and any additional testing dependencies, is installed as part of a
composer install, helpful when you are cloning a package's git repository. Please see https://phpunit.de/manual/current/en/index.html for the full PHPUnit documentation.
For Framework 1.x releases, documentation for each package can be found in the
README.md file in the root of the repository. As of 2.0, each repository will have a dedicated
docs directory structure at a minimum uses the following format:
classes- This directory contains documentation about the package's classes, interfaces, and traits, including summaries of the object's purpose and example uses
index.md- This is a file which will be used as a navigational menu when the package documentation is integrated into this site
overview.md- This is an overview of the package and its use
v1-to-v2-update.md- This file will highlight backward compatibility breaking changes in each package while migrating from 1.x to 2.0
The documentation files use GitHub Flavored Markdown. When contributing new features to existing packages, please add notes about the new features to the existing
README.md file in the packages you change or add new files to the
docs directory (depending on the branch you are submitting the change to). When submitting new packages, documentation in the form of a
README.md file will be required with your pull request. The package documentation should explain how a developer should should be able to get started using the code in the package. The documentation should give an explanation of the classes, interfaces, and/or traits, and provide several simple examples.
