AddressBook Level 3 (AB3) is a **desktop app for managing contacts, optimized for use via a Command Line Interface** (CLI) while still having the benefits of a Graphical User Interface (GUI). If you can type fast, AB3 can get your contact management tasks done faster than traditional GUI apps.

* Table of Contents
{:toc}

--------------------------------------------------------------------------------------------------------------------

## Quick start

1. Ensure you have Java `11` or above installed in your Computer.

1. Download the latest `addressbook.jar` from [here](https://github.com/se-edu/addressbook-level3/releases).

1. Copy the file to the folder you want to use as the _home folder_ for your AddressBook.

1. Open a command terminal, `cd` into the folder you put the jar file in, and use the `java -jar addressbook.jar` command to run the application.<br>
A GUI similar to the below should appear in a few seconds. Note how the app contains some sample data.<br>

1. 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.<br>
Some example commands you can try:

* `list` : Lists all contacts.

* `add n/John Doe p/98765432 e/[email protected] a/John street, block 123, #01-01` : Adds a contact named `John Doe` to the Address Book.

* `delete 3` : Deletes the 3rd contact shown in the current list.

* `clear` : Deletes all contacts.

* `exit` : Exits the app.

1. Refer to the [Features](#features) below for details of each command.

--------------------------------------------------------------------------------------------------------------------

## Features

<div markdown="block" class="alert alert-info">

**:information_source: Notes about the command format:**<br>

* Words in `UPPER_CASE` are the parameters to be supplied by the user.<br>
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.<br>
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.<br>
e.g. `[t/TAG]…​` can be used as ` ` (i.e. 0 times), `t/friend`, `t/friend t/family` etc.

* Parameters can be in any order.<br>
e.g. if the command specifies `n/NAME p/PHONE_NUMBER`, `p/PHONE_NUMBER n/NAME` is also acceptable.

* Extraneous parameters for commands that do not take in parameters (such as `help`, `list`, `exit` and `clear`) will be ignored.<br>
e.g. if the command specifies `help 123`, it will be interpreted as `help`.

* If you are using a PDF version of this document, be careful when copying and pasting commands that span multiple lines as space characters surrounding line-breaks may be omitted when copied over to the application.

--------------------------------------------------------------------------------------------------------------------

## FAQ

**Q**: How do I transfer my data to another Computer?<br>
**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.
