• The grade can be any whole number between 0 and 100, inclusive.

Important Notes:

• Each module specified in the grade command must be a module that the student is taking.
• The number of m/MODULE prefixes must match the number of s/GRADE prefixes.
• Grades are assigned to modules based on the order of the m/MODULE s/GRADE pairs provided in the command.

Examples:

• grade 1 m/CS2103T s/85 assigns a grade of 85 to CS2103T for the first student.
• grade 2 m/MA1522 s/90 assigns a grade of 90 to MA1522 for the second student.

Autocomplete

The Autocomplete feature provides real-time command suggestions as you type, helping you quickly and accurately enter commands. Autocomplete identifies keywords and suggests matches, allowing you to streamline input by selecting from relevant options instead of typing full commands or field values.

How It Works

Autocomplete operates based on the word at the caret position:

• As you begin typing a command or field, suggestions will appear that match your input. For example, typing ad will display a list of commands beginning with ad, like add.
• Autocomplete for command keywords applies only to the first word you type in the command box. This initial word is treated as the command.
• Autocomplete for student fields applies to all subsequent words after the first word. All subsequent words after the first are treated as student fields with specific prefixes.

Note: Autocomplete will not match subsequent words after the first word with command keywords!

Supported Fields

Autocomplete currently supports the following fields with these prefixes:

When these prefixes are detected, autocomplete automatically displays a list of suggestions related to these fields. The list of suggestions are generated through the existing list of students inside StoreClass.

Example Usage

If you begin typing edit 1 m/M, Autocomplete will provide suggestions for available modules starting with the letter M, helping you to quickly select the correct module name. Similarly, typing t/ after the command will bring up a list of tags, allowing you to specify tags accurately without needing to remember or retype exact names.

Common Question: Why are there no suggestions when I type in m/, t/ or pa/?
Autocomplete searches for suggestions relevant to these fields based on the existing data in StoreClass. If there are no data or students inside StoreClass, then no suggestions will be generated for these fields. This usually occurs after a clear command.

By utilizing Autocomplete, you can input commands more quickly, reduce typos, and improve your overall efficiency in navigating the software!

Saving the data

AddressBook data are saved in the hard disk automatically after any command that changes the data. There is no need to save manually.

Editing the data file

AddressBook data are saved automatically as a JSON file [JAR file location]/data/addressbook.json. Advanced users are welcome to update data directly by editing that data file.

Caution: If your changes to the data file makes its format invalid, AddressBook will discard all data and start with an empty data file at the next run. Hence, it is recommended to take a backup of the file before editing it.
Furthermore, certain edits can cause the AddressBook to behave in unexpected ways (e.g., if a value entered is outside of the acceptable range). Therefore, edit the data file only if you are confident that you can update it correctly.

FAQ

Q: How do I transfer my data to another Computer?
A: Install the app in the other computer and overwrite the empty data file it creates with the file that contains the data of your previous AddressBook home folder.

Known issues

1. When using multiple screens, if you move the application to a secondary screen, and later switch to using only the primary screen, the GUI will open off-screen. The remedy is to delete the preferences.json file created by the application before running the application again.
2. If you minimize the Help Window and then run the help command (or use the Help menu, or the keyboard shortcut F1) again, the original Help Window will remain minimized, and no new Help Window will appear. The remedy is to manually restore the minimized Help Window.
