Developers are free to use whatever tools they prefer, but this page provides some suggestions that may help newcomers make the most of VuFind development.
Editors / IDEs
Some developers prefer to use a simple text editor to quickly and easily edit individual files. Others prefer a full-fledged IDE (Integrated Development Environment) which imposes a “whole project” view of the code and includes a built-in understanding of the code which enables it to detect errors, make suggestions and offer navigational shortcuts during programming. As a general rule, an IDE has a steeper learning curve than a basic editor and consumes more resources; however, it offers great advantages when undertaking more complex programming tasks. Basic text editors can offer more speed, and some also include plug-ins to enable certain IDE-like functionality.
It is strongly recommended that you use some sort of version control software to keep track of revisions while programming. This provides a valuable safety net for reverting bad changes, remembering why particular adjustments were made, etc. In the case of Git, the tool used by VuFind, it also offers powerful collaboration and sharing capabilities. Whether you plan to work locally or share with the local community, Git is a tool worth learning more about, as is the GitHub platform, which enhances Git's native sharing capabilities with web-based collaboration tools.
VuFind loads its external dependencies using Composer. An understanding of Composer is important when running VuFind from a source checkout or when adding new third-party libraries.
VuFind, as of version 3.1, ships with a Gruntfile to help manage front end tasks like compiling less/scss, compressing js, and checking coding standards. See the documentation to get started.
Meeting Project Standards
The VuFind project includes unit tests and automated code style checks designed to insure the consistency and integrity of the code. Whenever a Git commit is made or a GitHub pull request is opened, continuous integration processes run to validate the changes, and alerts will be thrown if anything breaks.
The unit tests page talks about how to run tests locally.
For style compliance, VuFind uses PHP_CodeSniffer and PHP-CS-fixer, each of which is capable of detecting (and sometimes automatically fixing) different issues. In recent versions of VuFind, these tools will be installed automatically by Composer.
To test style compliance with PHP_CodeSniffer while in your VuFind directory, you can test a single file with:
vendor/bin/phpcs --standard=PEAR [file]
Or, through Phing, you can check the whole project:
To automatically fix certain PHP_CodeSniffer issues, you can run:
To automatically fix additional issues with php-cs-fixer, from the base of your VuFind directory, run:
If you are unwilling or unable to run these tools locally, note that if you open a pull request against the main VuFind repo, they will be automatically run by continuous integration and you can view a list of issues in the resulting Travis report. Before you spend time manually fixing anything, you can post a comment on the pull request to ask for assistance with running the automatic processes.
