Developer Tools (devel)

This module contains helper functions for Backdrop developers. It provides a wide array of tools for examining the functionality of your site, including:

• Displaying a list of all SQL queries executed per page.
• Integrating with XHProf to show what PHP was executed and identify slow calls.
• Executing arbitrary PHP.
• Switch between different users.
• Report memory usage at the bottom of each page.
• A mail-system class which redirects outbound email to files.
• Utility functions for dumping variables to the page or messages area.

Although the abilities of this module are restricted to a permission ('access development information'), it's a good idea not to have this module enabled on production servers due to its exceedingly dangerous functionality.

The most common functions for dumping variables include:

• dpr(): Prints a variable using print_r() to the messages area.
• dpm(): Prints a variable using the krumo library to the messages area.
• dvm(): Prints a variable using var_export() to the messages area.

All of these functions will only show the messages to users that have the 'access development information' permission.

Included in this package is also:

• devel_node_access module which prints out the node_access records for a given node. Also offers hook_node_access_explain for all node access modules to implement. Handy.
• devel_generate.module which bulk creates nodes, users, comment, terms for development.
