Cgiapp2 Tutorial 2 - Pluggable Applications
Jun 07, 2006 @ 06:17:36

Matthew Weir O'Phinney has created yet another tutorial surrounding the Cgiapp2software and looks this time at something he calls "pluggable applications".

He gives the example of needing a method for creating a well-structured layout in his appication, but also needing a sitewide template to apply to it. Traditional methods don't quite lend themselves to that, so he introduces a new function, cgiapp_postrun, to apply the template after the logic is through.

He includes two examples, one demonstrating the above mentioned situation and the other showing how to make a flexible method for including authentication in only certain parts of the application and not others. Both define a postrun() function to handle the changes to be made after the rest of the logic has finished.

Cgiapp2 Tutorial 1 - Switch Template Plugins at Will
Jun 06, 2006 @ 05:47:28

Right on the tails of a new release of the Cgiapp set of libraries, Matthew Weir O'Phinney has posted a first tutorial in a series covering its usage. In this tutorial, he looks at a creating a "template switcher" for Cgiapp2-based applications.

Cgiapp2 implements a new callback hook system, which is basically an Observer pattern. Cgiapp2 has a number of registered hooks to which observers can attach; when a hook is triggered, each observer attached to it is notified and executed.

Why all this talk about hooks? Because in Cgiapp2, the various template actions -- initialization, variable assignment, and rendering -- are relegated to hooks. For simplicity's sake, and for backward compatibility, you can use the functions tmpl_path(), tmpl_assign(), and load_tmpl() to invoke them; you could also use the generic call_hook() method to do so, passing the hook name as the first argument.

To make it simpler for developers to access this templating system, Matthew created the Cgiapp2_Plugin_Template_Interface, a standardized interface for the template plugins. It's this interface that he demonstrated an example of, giving only a few lines of code (all that's needed) to switch between Smarty and Savant templating systems.
