Community Color - Source Code

Source Code Viewer

This page lets you view source code from my server. The program uses a brute force code formatter to color code elements. NOTE: I wrote this program while trying to learn the vim text editor. This is not my usual coding style.

Formatted Code

Below is the code all formatted with bright colors. The program links to files opened with include() and expands those opened with require(). Clicking on the require line should change visibility. You can view the database schema with schema viewer.
