Analysis

Overview

The goal of this task is to develop a concept of describing Changes with useful end-user information.

This includes:

• Reviewing current implementation for information and descriptions associated with Changes
• Giving ideas for new types of Change descriptions which will be useful for the end-user
• Devising a mechanism to implement the ideas above internally

Task requirements

• Information about changes should be classified by types and implemented:
  • Description
    • When the user is undoing/redoing a change, this results in a top-level change which should have meaningful description
    • Internal side effect changes could also have useful descriptions
  • Whether the change is a main or a side effect
  • Unique sequence id of the change
    • When Changes occur, they are sorted in order of appearance so each Change should have a unique id
    • The smaller the id of a Change, the earlier in time it has occurred
  • When the end-user views a top-level change, besides description there should be also a timestamp of the Change, e.g. when it has occurred
• Develop a UI tool which shows the tree of Changes for debugging purposes
• Develop a proper way to visualize what kind of effects undoing/redoing a Change would have
• Create new unit tests

Task result

• Description of the information a Change provides in the wiki page
• New code to implement the desired functionality
• Description of the UI tool in the wiki

Implementation idea

• Use the Inspector for a base of the UI tool
