1. Introduction

NSync is a program for NUS students who strive to keep their lives organised, despite their busy schedules. Interested? Jump to the Section 2, “Quick Start” to get started. Enjoy!

2. Quick Start

Ensure you have Java version 9 or later installed in your Computer.
Download the latest addressbook.jar here.
Copy the file to the folder you want to use as the home folder for your Address Book.
Double-click the file to start the app. The GUI should appear in a few seconds.
Download the addressbook.xml file at this link https://github.com/CS2113-AY1819S1-W12-2/main/releases/tag/V1.4 and replace your own data file with it to get 20 normal contacts and 7 merged contacts.
Type the command in the command box and press Enter to execute it.
e.g. typing help and pressing Enter will open the help window.
Some example commands you can try:
- list : lists all contacts
- addn/John Doe p/98765432 e/johnd@example.com a/John street, block 123, #01-01 : adds a contact named John Doe to the Address Book.
- deletemain 3 : deletes contact whose index number is 3
- exit : exits the app
Refer to Section 3, “Features” for details of each command.

3. Features

Command Format

Words in UPPER_CASE are the parameters to be supplied by the user e.g. in add n/NAME, NAME is a parameter which can be used as add n/John Doe.
Items in square brackets are optional e.g n/NAME [t/TAG] can be used as n/John Doe t/friend or as n/John Doe.
Items with … after them can be used multiple times including zero times e.g. [t/TAG]… can be used as (i.e. 0 times), t/friend, t/friend t/family etc.
Items with 1.. after them can be used multiple times, excluding zero times e.g. [ENROLLED MODULE]1..
Parameters can be in any order e.g. if the command specifies n/NAME p/PHONE_NUMBER, p/PHONE_NUMBER n/NAME is also acceptable.

3.1. General Commands

3.1.1. Listing entered commands : `history`

Lists all the commands that you have entered in reverse chronological order.
Format: history

Pressing the ↑ and ↓ arrows will display the previous and next input respectively in the command box.
For privacy reasons, downloadAllNotes and downloadSelectNotes commands will not be saved to history. This is because those commands contain the user’s IVLE password.

3.1.2. Exiting the program : `exit`

Exits the program.
Format: exit

3.1.3. Saving the data

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

3.2.2. Adding a person: `add`

Adds a person to the address book
Format: add n/NAME p/PHONE e/EMAIL a/ADDRESS [t/TAG]…[em/ENROLLED MODULE]…

If you somehow lose your self contact, you can create a new one by adding t/self to your add command. Adding any other tag will not have any effect on the contact created. Self contacts cannot be deleted through the interface so do not add another self contact if you already have one that exists.

Examples:

add n/John Doe p/98765432 e/johnd@example.com a/John street, block 123, #01-01
add n/Betsy Crowe t/friend e/betsycrowe@example.com a/Newgate Prison p/1234567 em/CS2113T

Format: free f/[SELF/INDEX] …

Example 1: free f/self
Running this command will show your next available time-slot (from current time).
With reference to the time-table found in the figure above, if the current day and time is Monday 3:00pm, your next available time-slot shown is Monday 4:00pm till 8:00pm. If the current day and time is Monday 4:34pm, your next available time-slot shown is Monday 4:34pm till 8:00pm.

Example 2: free f/1 f/7 f/9

Running this command outside the day window of Monday to Friday or beyond the time of 8pm will return a time-slot from the next weekday.

3.3.6. Export user data: `export`

Met a new acquaintence who would like to have your contact details and time-table to schedule a common meeting time? export allows you to export all of a user’s (or your own) details in each respective field into an encoded string. (Once you have sent the string to another NSync user, he/she can use import to retrieve the data within the encoded string - see import for more details)
Format: export PUBLIC/PRIVATE SELF/INDEX

Type 'public' if you would like the user who imports your contact to see the full contents of your time-table.
Type 'private' if you would like the user who imports your contact to see only your free and busy time-slots respectively (i.e. specific contents of your time-table are hidden!).

All examples shown below are with reference to the sample time-table shown in the figure above.

Example 1: export public self
The importing user will see your time-table in its entirety (i.e. the full contents of the time-table), exactly as shown in the sample time-table above.

Example 2: export private self
The importing user will see only the busy and free time-slots in your time-table, marked as black and white colored slots respectively, as seen in the figure below.

The generated string from the command will be automatically copied for you (no manual selecting and copying required)! All you have to do is to send it in its entirety to a fellow NSync user who will import it.

When exporting a time-table with only free and busy time-slots (i.e. black and white slots), it does not matter if you select either the public or private option - the user who imports your generated string will see the same time-table.

Exporting more than 1 user’s details at a time or exporting a merged time-table is currently not available (but will be implemented in future releases!).

3.3.7. Import user data: `import`

Did you receive an encoded string from a fellow NSync user? Use import to transfer all of the data within the string into your copy of NSync!
Format: import [PASTE_YOUR_ENCODED_STRING_HERE]

Display Message 1: Import Successful!
If you have imported a valid contact who is currently not in your NSync (i.e. no contact with the same name), all of the imported user’s details will now be found in your NSync.

If you see only black and white colored slots in the time-table of the imported contact, it means that the exporting user could have chosen the private option during the export process. See export for more details.

Display Message 2: Import Successful! An existing contact has been found in NSync and has been overwritten.
If you have imported a valid contact who is currently already in your NSync (i.e. contact with the same name), all of the details found in the imported string will overwrite the existing ones found in your NSync, for that particular contact.

If you have unintentionally over-written the details of an existing contact, use undo to get back the original details of the contact!

Display Message 3: Import Failed!
If you have missed out a character, or accidentally modified one of the characters in the string, attempting to import the invalid string will result in an error displayed. Please obtain a valid string from the contact who passed it to you.
