* \mainpage Shimmie2 / SCore Documentation
|
|
*
|
|
* SCore is a framework designed for writing flexible, extendable applications.
|
|
* Whereas most PHP apps are built monolithically, score's event-based nature
|
|
* allows parts to be mixed and matched. For instance, the most famous
|
|
* collection of score extensions is the Shimmie image board, which includes
|
|
* user management, a wiki, a private messaging system, etc. But one could
|
|
* easily remove the image board bits and simply have a wiki with users and
|
|
* PMs; or one could replace it with a blog module; or one could have a blog
|
|
* which links to images on an image board, with no wiki or messaging, and so
|
|
* on and so on...
|
|
*
|
|
* Dijkstra will kill me for personifying my architecture, but I can't think
|
|
* of a better way without going into all the little details.
|
|
* There are a bunch of Extension subclasses, they talk to each other by sending
|
|
* and receiving Event subclasses. The primary driver for each conversation is the
|
|
* initial PageRequestEvent. If an Extension wants to display something to the
|
|
* user, it adds a block to the Page data store. Once the conversation is over, the Page is passed to the
|
|
* current theme's Layout class which will tidy up the data and present it to
|
|
* the user. To see this in a more practical sense, see \ref hello.
|
|
*
|
|
* To learn more about the architecture:
|
|
*
|
|
* \li \ref eande
|
|
* \li \ref themes
|
|
*
|
|
* To learn more about practical development:
|
|
*
|
|
* \li \ref scglobals
|
|
* \li \ref unittests
|
|
*
|
|
* \page scglobals SCore Globals
|
|
*
|
|
* There are four global variables which are pretty essential to most extensions:
|
|
*
|
|
* \li $config -- some variety of Config subclass
|
|
* \li $database -- a Database object used to get raw SQL access
|
|
* \li $page -- a Page to holds all the loose bits of extension output
|
|
* \li $user -- the currently logged in User
|
|
*
|
|
* Each of these can be imported at the start of a function with eg "global $page, $user;"
