<p>Anything thing that creates a properly formatted XDebug trace file can use the Visualize Backtrace module to parse and process it into a *.dot function call stack visualization. </p>
<p>In some cases, you can just copy and paste the trace file into the folder. But in other cases, you may want to run another PHP application, and get dynamic backtrace visualizations.</p>
<p>This means that you could run Joomla!, Wordpress, PHPMyAdmin, CiviCRM within a subdirectory of a Drupal installation, and dynamically graph their function call stacks into a flowchart.</p>
<p>I did this as a test in preparation for my Drupal Camp presentation, and thought that I'd pass it along here.</p>
<p>Here's how I was able to do this.</p>
<p>1.) Enable the XDebug traces from the root .htaccess of a localhost Drupal installation. (<a href="http://localhost/">http://localhost/</a>)<br>
2.) Create a second Drupal installation as a subdirectory of the first installation. Say for example, in a folder named "d53" (i.e. (<a href="http://localhost/d53">http://localhost/d53</a>))<br>
3.) Also install Joomla/Wordpress/whatever as a subdirectory of the root Drupal installation. Add a prefix of "d53_" to the folder, so that it reads "d53_joomla" and appears at <a href="http://localhost/d53_joomla">http://localhost/d53_joomla</a><br>
4.) Copy the contents of the "d53_joomla" folder in as a subdirectory of the "d53" folder, and rename it to just "joomla" (i.e. at /library/webserver/documents/d53/joomla)<br>
5.) Copy the Joomla-specific color codes listed down below into the visualize_backtrace_get_lookup_table_values() function after the line <code>else if ($source_code_link_location == "local") {</code> in the "d53" version of the visualize_backtrace.module<br>
6.) Create an XDebug trace file on the joomla installation by doing a page load at <a href="http://localhost/d52_joomla">http://localhost/d52_joomla</a><br>
7.) Go to the trace files listed at the d53 installation at: <a href="http://localhost/d53/view_traces">http://localhost/d53/view_traces</a>, and the second to the top trace files will be from the joomla installation. Click on the trace files from here, and be able to dynamically graph the call stacks and link back to the source code.</p>
<p><strong>NOTE:</strong> This works because the base path of <code>/library/webserver/documents/d52/</code> is being deleted from the beginning of the <strong>/library/webserver/documents/d52_joomla/<strong> XDebug filenames, and therefore correctly links up to the source code located in the d53 subdirectory. In other words, the joomla source code line numbers will be properly linked to at <strong><a href="http://localhost/d53/view_source/joomla/index.php">http://localhost/d53/view_source/joomla/index.php</a></strong>. </strong></strong></p>
<p>So be sure that the "Local Copy"is selected for the "Display Source Code Located at:" admin option.</p>
<p>Here are the file-specific color codes for Joomla.<br>
These probably could be spun off into an *.inc file along with other optional programs like Wordpress, CiviCRM, etc.<br>
Otherwise the entire *.dot visualization will be entirely grey, which is hard to visually parse.</p>
