/**
|
|
* Parses text in a variety of ways.
|
|
*
|
|
* Called from a template by $Content.Parse(SubClassName), similar to $Content.XML.
|
|
* This will work on any Text database field (Or a sub-class, such as HTMLText,
|
|
* although it's usefulness in this situation is more limited).
|
|
*
|
|
* Any sub-classes of TextParser must implement a parse() method.
|
|
* This should take $this->content and parse it however you want. For an example
|
|
* of the implementation, @see BBCodeParser.
|
|
*
|
|
* Your sub-class will be initialized with a string of text, then parse() will be called.
|
|
* parse() should (after processing) return the formatted string.
|
|
*
|
|
* Note: $this->content will have NO conversions applied to it.
|
|
* You should run Covert::raw2xml or whatever is appropriate before using it.
|
|
*
|
|
* Optionally (but recommended), is creating a static usable_tags method,
|
|
* which will return a SS_List of all the usable tags that can be parsed.
|
|
* This will (mostly) be used to create helper blocks - telling users what things will be parsed.
|
|
* Again, @see BBCodeParser for an example of the syntax
|
|
*
|
|
* @todo Define a proper syntax for (or refactor) usable_tags that can be extended as needed.
|
|
* @package framework
|
|
* @subpackage misc
