Behavior System

The new behavior system will unify template/record/generator under one topic and will be implemented in an unobtrusive way that avoids clashes of methods making the implementation robust to the future of behaviors (there will probably be a lot).

The basic idea revolves around Entity::getBehavior($name) and is conceptually the same as the Extension Object pattern: http://www.vincehuston.org/dp/extension_object.html.

Idea for pluggable extensions

Ability to install/remove behaviors, validator, utilities, etc in an easier way, by calling a single command.

blanco@blanco-laptop:/var/www/Doctrine$ php ./doctrine install behaviors/Geographical
Install OK
blanco@blanco-laptop:/var/www/Doctrine$ php ./doctrine remove validators/Email
Remove OK
blanco@blanco-laptop:/var/www/Doctrine$ php ./doctrine install utilities/Pager
Install OK

My wish is to go a bit ahead... suppose we have svn repositories for each plugin:

+ Pager
|-+ branches
| |-+ 0.11
| | |-+ Pager
| | | |-- ...
| | |-- Pager.php
| |-- ...
|-+ tags
| |-- ...
|-+ trunk
| |-- ...

Of course we could make the automatic task to build the repository as we wish, with svn:external entries. The idea is to always check out the branch of the current installed version of Doctrine (which means... if we have 1.0 installed, it'll try to checkout branches/1.0):

blanco@blanco-laptop:/var/www/Doctrine$ php ./doctrine install behaviors/Geographical
Doctrine extensions installer initializing...

Cannot continue, you do not have svn installed in your machine. Please run: 'sudo apt-get install subversion'

blanco@blanco-laptop:/var/www/Doctrine$ sudo apt-get install subversion
...

blanco@blanco-laptop:/var/www/Doctrine$ php ./doctrine install behaviors/Geographicalllll
Doctrine extensions installer initializing...

Unable to find 'Geographicalllll' in behaviors.

blanco@blanco-laptop:/var/www/Doctrine$ php ./doctrine install behaviors/Geographical
Doctrine extensions installer initializing...

Creating folder...                
[ OK }

Checking out repository...
A behaviors/Geographical/Geographical.php
A behaviors/Geographical/Geographical/Exception.php
A behaviors/Geographical/README.txt

Install OK

blanco@blanco-laptop:/var/www/Doctrine$ php ./doctrine update behaviors/Geographical
Doctrine extensions updater initializing...

U behaviors/Geographical/README.txt

Update OK

blanco@blanco-laptop:/var/www/Doctrine$ php ./doctrine update behaviors
Doctrine extensions updater initializing...

Updating Geographical...
[ OK }

Updating Timestampable...
U behaviors/Timestampable/Timestampable.php
U behaviors/Timestampable/README.txt
[ OK ]

blanco@blanco-laptop:/var/www/Doctrine$ php ./doctrine update
Unable to start Doctrine extensions updater. Please define the extension to be updated, example: './doctrine update validators'.

blanco@blanco-laptop:/var/www/Doctrine$

I think that would be a great possibility if we could do that... Comments???
