Introduction

With the transition to Canvas, the most important feature of LumiNUS’s deadline reminders is gone! NUS To-Do List aims to bring an application to keep you aware of your deadlines and not miss them.

Quick Start

1. Ensure that you have Java 11 or above installed.
2. Download the latest version of NUS To-Do List from here.
3. Run java -jar NUSTo-DoList.jar in a terminal to start the program.

Command Format

Flags

• Words with a dash in front such as -due or -email, are considered as flags. Hence, parameters like the description or tags cannot start with a dash.
• Each command has its own flags that need to be provided when running the command, some of which are mutually exclusive.
• A typo in a flag may cause it to be recognised as a parameter instead of a flag.
• You cannot repeat the same flag (-edit abc -edit def) for a command.
• Flags in square brackets [] are optional. (Do not include the brackets in the command)

Parameters

• Words in UPPER_CASE are parameters to be supplied by the user.
• Parameters cannot start with a dash -. For example, add -random_name is an invalid command.
• Flags and their parameters can be provided in any order after the command name and its parameter. For example, instead of add DESCRIPTION -due DATE -email ADDRESS you can also use add DESCRIPTION -email ADDRESS -due DATE.
• Unnecessary parameters for commands/flags that do not need them are ignored. For example, exit 123 is equivalent to exit.

Restrictions

Given below is list of task attributes and their restrictions.

• DESCRIPTION A task must have a non-empty description.
  • Examples: Hello yah, pi is roughly 3
• DEADLINE The date-time format is dd/mm/yyyy hh:mm or dd-mm-yyyy hh:mm.
  • When adding a task or editing a deadline, the DEADLINE cannot be in the past.
  • Examples: 14/03/2025 16:40, 29/02/2024 06:39
• EMAIL_ADDRESS must be of a valid email address format. (We do not check if the mailbox actually exists.)
  • Examples: abc@def.com, this-is-valid-@too.com
• LIST_OF_TAGS consists of one or more tags, separated by a space. A task cannot have multiple of the same tag.
  • Tags will be sorted in lexicographic order.
  • Examples: difficult later 3.14, ALSO_A_TAG
• REPEAT_TIMES must be an integer from 0 to 2147483647, and can only be used if the task also has a DEADLINE.
  • A copy of the task (with a new id) will be added every REPEAT_FREQUENCY days (defaults to 7) starting from the DEADLINE for REPEAT_TIMES times.
  • Examples: 37, 0 (the default if not specified, equivalent to no recurrence)
• PRIORITY_LEVEL can be either 1, 2, or 3 (1: Low, 2: Medium, 3: High).
  • A priority of 0 (the default if not specified) can also be used to indicate no priority.

Selecting tasks

Some commands can act on multiple tasks at once, which can be selected by providing a list of ids, OR one or more filters.

• IDS consists of one or more ids, separated by a space.
  • IMPORTANT: Ids (indicated with ID:) are different from the ordering number of a task (indicated with #). Each task has a unique, fixed id number used to select that specific task. Hence, ids do not reset without using the reset command.
  • A command will not be executed if any of the provided ids are invalid (not in the task list).
  • Commands will be executed as if the list of ids is provided in increasing order.
  • Examples: 1 3 5, 99
• FILTERS can be one or more of the following:
  • Boolean filters
    • Replace 1 with 0 to invert the filter.
    • -done 1 filters completed tasks.
    • -overdue 1 filters overdue (incomplete and past deadline) tasks.
    • -rep 1 filters recurring (REPEAT_TIMES > 0) tasks.
  • Non-boolean filters
    • -all selects all tasks (this overrides all other filters).
    • -desc STRING filters tasks with descriptions containing the given string.
    • -email EMAIL_ADDRESS filters tasks with the given email address.
    • -before DEADLINE filters tasks with deadlines before the given deadline.
    • -after DEADLINE filters tasks with deadlines after the given deadline.
    • -tags LIST_OF_TAGS filters tasks that have all the given tags.
    • -prio PRIORITY_LEVEL filters tasks with the given priority level.
  • Example: -done 0 -desc next selects all incomplete tasks with next in their description.

Others

• Trailing, leading or consecutive spaces will be removed from commands.
• Certain commands that have no effect, such as deleting a non-existent attribute from a task or marking an already complete task, can still be executed anyway.

Features

Show progress of tasks that are due this week progress

Displays the progress of and lists tasks that are due this week in To-Do list. Progress is shown in the form of a percentage (up to 2 decimal places) and a progress bar (where = denotes the proportion of tasks completed and - denotes the proportion of tasks that are left undone). Called automatically on startup.

• “this week” starts from Monday to Sunday of the current week.
• For example, if progress is used at any time on 06/04/2023 (Thursday), “this week” would include any time within 03/04/2023 00:00 (Monday 12:00AM) to 09/04/2023 23:59 (Sunday 11:59PM).

Format: progress

View/Edit configurable settings config

Displays/edits the current configuration for repeating tasks.

Format: config OR config [-repfreq REPEAT_FREQUENCY] [-chkfreq CHECK_FREQUENCY] OR config -reset

• REPEAT_FREQUENCY is in days and must be an integer from 1 to 2147483647.
  • Tasks will recur, creating a copy of themselves (with a new id) if it has been at least REPEAT_FREQUENCY since their deadline.
• CHECK_FREQUENCY is in minutes and must be an integer from 0 to 2147483647.
  • The program will check for recurring tasks on startup and when a command is executed if it has been at least CHECK_FREQUENCY minutes since the last check.
  • A CHECK_FREQUENCY of 0 will mean that the program will check for recurring tasks every time a command is executed.
• config -reset will cause configuration settings to be reset to the default (equivalent to config -repfreq 7 -chkfreq 0).
  • -reset will override -repfreq and -chkfreq if provided together.

Example of usage and output: config displays the current configuration settings.

Here are the configuration settings for your system:
Repeating tasks every 7 days
Checking for repeating task every: 0 minutes

config -chkfreq 5 -repfreq 3 sets tasks to repeat every 3 days and the check for recurring task to every 5 minutes.

Okay, I have changed the configuration to as follows:
Repeating tasks every 3 days
Checking for repeating task every: 5 minutes

View help List help

FAQ

How do I transfer my data to another computer?

• Your task list is saved in the generated data.json file, and configs are saved in the config.json file.
• Copy these files to the other computer and place them in the same location as the jar file for the program before running it.

Can I edit my save/config file using a text editor?

• Yes, but this is not recommended unless you know what you are doing.
• If your save/config file is invalidated and cannot be loaded, it will be copied to invalid_data.json and invalid_config.json, while your task list/config settings will be reset.

Why was my recurring task details not updated with the original task?

• The recurring tasks that are automatically added by the system are not linked to the original task.
• If you wish to change the task details for future recurring tasks, you may edit the latest task added by the system before the current deadline.
