= Analysis =

== Overview ==

 * After the TEXT_MODEL_REDESIGN task the positions of the caret and mark in the text views are not updating.
 * The text links and the search highlights are not visualizing.

 After the task these two bugs shold be fixed.

== Task requirements ==

 * Fix the updating of the caret, mark and search highlights position.
 * Implement search highlight visualization in the text views.
 * Implement link attachment visualization (as foreground color) in the text views.

== Task result ==

The result should be code.

== Implementation idea ==

 * Create a new class related to the text views that updates the indexes.
 * Create processors to help text layout draw the search highlights.
 * The processors add some attributes to the raw text (the text in the model) and produce a final text with all attributes added (as highlights and selection etc.) that can be laid out.

== How to demo ==

 * Run sophie, insert text frame, type some text, select some of the text.
 * Run sophie, insert text frame, type some text, add text link.
 * Run sophie, insert text frame, search an existing word from the search palette.
 
= Design =
 * Make interface TextProcessor. It will have: 
   * Empty interface Options. This is the criteria for processing the text, e.g. highlight color, caret position, highlight interval, etc.
   * Interface Effect. This consists of the resulting text after a processing and the change that is generated from it (the change that if applied to the raw text, the processed one will be the result).
    * public ImmText getText();  
    * public TextStyleChange getChange();  Note that the result is a Style change, that is, the processors will not e able to modify the text itself, but only its styles. Otherwise, weird navigation problems could occur with the current implementation :) 
   * ImmText process(ImmText sourceText, T procOptions); You give the processor a text and the rules for processing, then it returns the processed text. For example: TextSelectionProcessor, which has text 'abc' and options 'caret: 2, mark:1, color: red' will return 'abc' with colored in green 'b' and 'c', as well as a caret after the 'c'.
 * Make interface TextProcessotProvider: '''description'''.
 * Register extension point for TextProcessorProviders in BaseTextModule.
 * Implement selection processor
 * Implement text search processor
 * Implement text link processor
 * Make abstract class TextViewModel: 
  * public abstract ImmText getRawText();
  * public abstract ImmText getProcessedText();
  * public abstract int getCaret();
  * public abstract int getMark();
  * public abstract ImmList<ImmArea> getAreas();
  * public abstract boolean isEditable();
  * public abstract HotLayout getTextLayout(); 
  * public RwProp<HotStyleDef> inputStyle();
  * public HotTextInterval getSelectionInterval();
  * public RwProp<Float> wantedX();
  * public abstract Prop<ImmMap<HotTextInterval, Attachment>> attachmentMap();
  
 * replace TextViewFlow with TextViewModel
