[Owncloud] Re: Templating engine or not?

[Charles-Edouard Coste]

Hi everyone.

This is my point of view:

Template engines may make the application slower when compiling
templates.

But:
Template engine are better for team work because it adds an abstraction
layer for content rendering.
It's also more safe, because Html coders won't be able to access
dangerous functions like "unlink()", "chmod()", and so on...

Like François said PHP as its own template language. Usually, we should
use tags like:
<?php if( $hello ) : ?>
  <h1>Hello</h1>

instead of
<?php if( $hello ) { ?>
  <h1>Hello</h1>
<?php }; ?>

...as I suggested in this commit :
http://gitorious.org/owncloud/charlycostes-owncloud/commit/d726340c96602ce6b83f02a194a4981e833d5694

So maybe it's possible to make it more readable for you Bugsbane. But in
general, I agree with you : template engine is better.

By the way, the PHP code in the view file should be really easy to understand since it should only be basic "if else", "foreach" and "echo" statements, nothing really hard to figure out.

The ease of the template system plays a very large part in my decision of which CMS I am going to use for a project and I would not have a chance of creating anything useful if I had to work with straight PHP. For these reasons I *love* Joomla and despise Magento. Why? Because in Joomla the vast majority of any template is just html in the index.php file and css in the template.css file. Any PHP that does exist in there is typically one short, standard code snippet to include a module (similar to blocks in Drupal). I don't really need to know any code beyond 1 or two snippets and CSS. Compare this to the nightmare that is Magento where code is flung around multiple files in multiple locations and you need to know what just about all of them do to estimate why something looks the way it does and how to change it. Drupal is somewhere in the middle, albeit much better than Magento. Strangely enough, over 90% of websites (including http://krita.org ) that I've been in charge of creating use Joomla.

What I know is that HTML, CSS, Gimp and Inkscape are familiar and need no introduction. Every other file and protocol that's introduced is other specialty learning I'd have to study before helping out (ie a barrier to entry).
