Devel_Breakpointįorces the PHP interpreter to stop the same way as setting a breakpoint in an IDE. Without arguments, devel_message displays the full Twig context. Prints a complex data structure in an attractive way in the message area, the same as PHP function dpm(). Without arguments, devel_dump will display the full Twig context. Prints a complex data structure in an attractive way, the same as PHP function kpr(). Devel adds three new Twig functions for template developers:ĭevel_dump($var) devel_message($var) devel_breakpoint() Devel_Dump The Twig engine in core allows module developers to add new functions and filters to be used in templates (HTTP:// /doc/2.x/advanced.html). Devel provides a block that allows a quick switch between users. You can use Devel to inspect and edit both systems. Devel now provides report pages for services, routing, events, and many more. Services, Routing & Eventsĭrupal 8 adds a lot of new concepts and structures that developers need to understand to build new modules. When in vertical mode, the Toolbar shows links to all the available features. Toolbarĭevel is now directly integrated into the core Toolbar module. You can generate the printed array into a block, into a footer, or into a $messages box, like the "login successful" message that Drupal prints out automatically when a user logs in. If this happens to you, move this code snippet inside one of your module's functions rather than leaving it naked at the top of your module, and the error will stop. Even if devel exists, it might not be fully rendered as a set of PHP functions yet. Sometimes, depending on where your particular module falls in the core's own build process, you might be able to generate a fatal error by trying to call dprint_r() from inside your own module. There are several ways to implement it, and all of them require the devel module to work. It formats the array into a human-readable paragraph, rather than just displaying all the variables one after the other in an endless and mostly incomprehensible strand-like PHP's print_r() function would do. The dprint_r function is a tool for peeking inside of a Drupal array to see what's there.
