Ref debug

Using PHP-ref for debugging, using for example r() instead of devels dpm().

Dependencies

Libraries API and PHP-ref.

Install

Download the PHP-ref library, and place it in the the libraries folder.
Example:
sites/all/libraries/php-ref

Path for phpref.php should in the example be:
sites/all/libraries/php-ref/phpref.php

Usage

Enable Libraries module and Ref debug. Settings are available under admin/config/ref.

But to output the debugging information, you need to add the debugging functions in your code.

Basic usage from php-ref documentation:

Display info about defined classes

r(get_declared_classes());

Display info about global variables

r($GLOBALS)

To print in text mode you can use the rt() function instead:

rt($var);

To terminate the script after the info is dumped, prepend the bitwise NOT operator:

~r($var);   // html
~rt($var);  // text

Prepending the error control operator (@) will return the information:

$output = @r($var);   // html
$output = @rt($var);  // text

Keyboard shortcuts (javascript must be enabled):

X - collapses / expands all levels
