Analysis

The purpose of this task is to clarify text internals related to indexing of positions and the text history.

Overview

• Problems and difficulties of the current implementation of text
  • Indexing
    • Calculation of the indexes of HotPoses takes place in ImmHotText.
    • This makes ImmHotText responsible for too many functionality.
  • Text History (needed again for indexing)
    • Each ImmHotText refers to its previous and holds the last operation by which it has be created.
    • This is too complex and makes the history hard to save.
    • The history is not persisted at the moment, but it would be needed for tasks including server interactions and real-time collaboration.
  • The text classes are not well separated into packages (useless packages, etc.).

Task requirements

• Extraction of most of the responsibities for indexing calculations from ImmHotText.
• History representation simplifications.
• History persistence (optional).
• Appropriate package split of text classes.

Task result

• The result of this task is source code.

Implementation idea

• Move indexing responsibility to HotPos.
• Represent text history as a list of operations.
  • This will make history persistence easier.
• Remove useless packages (such as the smart package).
