Devel

Introduction

Devel module contains helper functions and pages for Drupal developers and inquisitive admins:

• A block and toolbar for quickly accessing devel pages
• A menu tab added to entities to give access to internal entity properties
• Urls created to view the internal entity properties even when there is no menu tab, for example /devel/paragraph/n
• Debug functions for inspecting a variable such as dpm($variable)
• Debug a SQL query dpq($query or print a backtrace ddebug_backtrace()
• A block for masquerading as other users (useful for testing)
• A mail-system class which redirects outbound email to files
• Drush commands such as fn-hook, fn-event, token, uuid, and devel-services
• Devel Generate. Bulk creates nodes, users, comment, taxonomy, media, menus, block content for development. Has Drush integration.

This module is safe to use on a production site. Just be sure to only grant access development information permission to developers.

Collaboration

• https://gitlab.com/drupalspoons/devel is our workplace for code, MRs, and CI.
• Create a personal fork in order to make an MR.
• We plan to move bck to drupal.org once it uses Gitlab for issues.
• We auto-push back to git.drupalcode.org in order to keep Security Team coverage and packages.drupal.org integration.
• Chat with us at #devel on Drupal Slack.
