#DRUPAL 9 TWIG VERSION MANUAL#

This manual is based on the experience of using the solutions described in real tasks, and I plan to continue to maintain it in an up-to-date state and supplement it with new examples as they appear. This is not an article for one-time reading, but a kind of list of ready examples, available in one click, in which you can quickly find the necessary example and use it in your task. Though there may be some bumps along the way, Xdebug-related errors are highly Googleable and being able to interactively debug Twig templates is awesome.This manual turned out to be quite voluminous, but I did not break it down into several parts for at least two reasons: Any time you spend on installation will be worth it later. Making Xdebug a part of your developer toolset will make you a far more efficient developer. Video Demonstration of XDebug in Twig Templates in Action: Most of the time you'll be looking at the $context variable for values that are available for use in the template. You've set a breakpoint in the twig template with If for some reason it's not working, you'll need to make sure Now that the hardest part is over, you can set a breakpoint in any twig template. Just make sure to select your IDE (like PhpStorm) as the IDE key.Įnable as you would with any other Drupal module.

Chrome users can use the XDebug helper extension.

If you already have Xdebug installed, scroll down to the 'Integrating Xdebug with PhpStorm' section.

Documentation for installing Xdebug with PhpStorm is available on the JetBrains website.

Just click 'Activate Xdebug' on the PHP tab of the MAMP PRO interface.Īn Integrated Development Environment (IDE) with XDebug listener enabled.

If you use MAMP, Xdebug is installed for you.

If you're not sure where to start I would try using either MAMP or DrupalVM for your local host. If you're not super comfortable managing your local development environment, taking the time to work through these installations will make you more proficient in the long run. Requirements/Installationįor many developers, the biggest impediment to using a proper IDE and debugger is the setup.

You can also step through code to find the functions that created said variable. Once installed, you'll be able to quickly inspect all the global and local variables available at a specified breakpoint in the code.

While this will get you pretty far, using a debugger like Xdebug can save you time. If you're a back end developer who is used to interactive debugging, or a front end developer looking to up your game in Drupal 8, it's time for you to start using Xdebug. Most Drupal developers are used to using dpm() in Drupal 7 and its Drupal 8 counterpart kint(). These instructions achieve the same as the previous one without using Composer or the Twig Xdebug module. Note: This is an updated version of an earlier post.
