Have you ever started to use a comprehensive open source for an own project? Even with a good manual in hands, it takes a while to understand where to find what. When we started using Zen-Cart as an engine for our internet shop, we added this first line editor to TT. All it does is to insert, edit or delete a hdebug() call as the first source line of all .PHP files in a project. Here is an example:
<?php
hdebug("es/pages/checkout_process/header_php.php", "?", "S:/SCRAPBOOK/ZENCART/INCLUDES/modules/pages/checkout_process/header_php.php");/*id*/
When you insert the first lines and use the source, hdebug gives you a list of all the programs called within the process you are evaluating. With a mouse click, you can modify this first line within the php source and remove lines from the hdebug output of the next evaluation of this process. See a screenshot to get an idea of this editor.
