Contributions to project

  • Code contributed: RepoSense link.

  • New feature: Added the ability to undo or redo a command.
    • What it does: undoing a command reverts all data to a state before the last command which modifies it, and redoing a command is reverting an undo command.
    • Justification: undoing and redoing commands are common features in all applications to prevent accidental usage of an incorrect command, by making it reversible.
    • Implemented PersistentUninurseBook, a wrapper class around a list of past versions of UninurseBooks, allowing the user to undo (or redo) to a previous state.
  • New feature: Added the ability to specify options to a command to modify its behaviour depending on the options.
    • What it does: commands can now take option flags which are specified before command parameters which modify the command’s behaviour, allowing each command word (such as add, edit, delete, and view) to be used for different purposes.
    • Justification: each command word can be reused for different purposes, making it more intuitive and easy to remember.
    • Implemented ParserUtil methods to parse the options in a command, and XYZGenericCommandParser which contains the behaviour of the add, edit, delete, and view commands depending on whether the user specifies certain options e.g. the EditGenericCommandParser will call EditPatientCommandParser if only the patient index option is specified, but will call EditTaskCommandParser if the patient index and task index option is specified.
  • New feature: Added the ability for find command to search for attribute-specific keywords.
    • What it does: find command can search for attribute-specific keywords e.g. only search certain keywords in NAME attributes.
    • Justification: allow users to search for specific patients by their attributes.
    • Implemented PatientMatchPredicate, which tests whether a patient matches the specified keywords in the find command, and XYZContainsKeywordsPredicate which tests whether a specific attribute of a patient contains the attribute-specific keywords.
  • New feature: Added the ability to navigate through the command history by using the ↑ and ↓ arrow keys.
    • What it does: using the ↑ and ↓ arrow keys will replace the text in the CommandBox with the previous/next command.
    • Justification: enhance the user experience by allowing the user to reuse previous commands more easily without retyping the command.
  • Enhancements to existing features:
    • Modified and generalized the clear command to only delete currently-displayed patients.
    • Modified recurring tasks’ frequency to recognize singular/plural forms.
  • Contributions to User Guide:
    • Added the glossary.
    • Added documentation for undo, redo, find, and clear commands.
    • Added documentation for the ability to navigate through the command history by using the ↑ and ↓ arrow keys.
    • Added the patient parameter summary section.
    • Added more explanation on editing a patient’s multi-valued attributes.
    • Fix un-centered images and broken hyperlinks.
    • Various minor grammatical fixes, consistency, and improvements.
  • Contributions to Developer Guide:
    • Updated the documentation and implementation for the undo/redo feature.
    • Added use case for undo/redo feature.
    • Updated several diagrams to include the implementation for the undo/redo feature.
