Hbnb: HolbertonBnb is AirBnb Clone, a complete web application that composed by :

• A Command interpreter to manipulate data without a visual interface.
• A website (the Front-end) that shows the final product to everybody: static and dynamic.
• A database or files that store data.
• An API that provides a communication interface between the front-end and data (retrieve, create, delete, update them).

In this project, we will implement the first part: The console.

This project composes of the following classes:

All models are handled by a storage engine defined in the FileStorage model.

The Console is command line interpreter, it manage the backend part of the HolbertonBnb application by managing objects and storing/persisting the objects from/to JSON file.

The console is executed in interactive mode by running ./console.py, and a prompt when be displaying and waiting for input:

$ ./console.py
(hbnb) help

Also in non-interactive mode by piping command to the executable console file:

$ echo "help" | ./console.py
(hbnb)

Documented commands (type help <topic>):
========================================
EOF help quit
(hbnb) 
$

$ cat test_help
help
$
$ cat test_help | ./console.py
(hbnb)

Documented commands (type help <topic>):
========================================
EOF help quit
(hbnb) 
$

## How to use the console

To show command help, we enter the command help:

$ ./console.py (hbnb) help

EOF help quit

(hbnb)

To quit the Console, press CTRL+D (to input EOF signal) or enter quit command:

$ ./console.py (hbnb) EOF $

$ ./console.py (hbnb) quit $

# Commands

Holberton console handles the followings commands:

* create: 
	* Creates a new instance of BaseModel, saves it (to the JSON file) and prints the id.
	* Usage: create <class name>

Example of creating a User:

$ ./console.py (hbnb) create User 82a6f205-779b-4292-8678-fb53c90fb64e (hbnb)

* show:
	* Prints the string representation of an instance based on the class name and id.
	* Usage: show <class name> <id>

Example of showing the User instance:

$ ./console.py (hbnb) show User 83880763-f364-4e70-8bc5-1ad5218378fe (hbnb) show User 83880763-f364-4e70-8bc5-1ad5218378fe [User] (83880763-f364-4e70-8bc5-1ad5218378fe) {'id': '83880763-f364-4e70-8bc5-1ad5218378fe', 'created_at': datetime.datetime(2023, 8, 10, 13, 29, 20, 460431), 'updated_at': datetime.datetime(2023, 8, 10, 13, 29, 20, 460436)} (hbnb)

* destroy:
	* Deletes an instance based on the class name and id (save the change into the JSON file).
	* Usage: destroy <class name> <id>

Example of destroying an instance of User that is already stored in the JSON file:

$ ./console.py (hbnb) destroy User 83880763-f364-4e70-8bc5-1ad5218378fe (hbnb)

* all:
	* Prints all string representation of all instances based or not on the class name.
	* Usage: all <class name> or all

Example of printing instances of all classes:

$ ./console.py (hbnb) all ["[BaseModel] (c07899a9-85f0-439b-851e-624bbb74b996) {'id': 'c07899a9-85f0-439b-851e-624bbb74b996', 'created_at': datetime.datetime(2023, 8, 10, 13, 42, 47, 772518), 'updated_at': datetime.datetime(2023, 8, 10, 13, 42, 47, 772525)}", "[BaseModel] (12f855f0-0b0e-44ab-baee-1d0e29d3a51f) {'id': '12f855f0-0b0e-44ab-baee-1d0e29d3a51f', 'created_at': datetime.datetime(2023, 8, 10, 13, 42, 49, 896756), 'updated_at': datetime.datetime(2023, 8, 10, 13, 42, 49, 896759)}", "[Place] (268500c2-ce81-428a-be70-e71b2ca61704) {'id': '268500c2-ce81-428a-be70-e71b2ca61704', 'created_at': datetime.datetime(2023, 8, 10, 13, 42, 55, 799743), 'updated_at': datetime.datetime(2023, 8, 10, 13, 42, 55, 799748)}", "[Place] (707a4dc3-e294-4d09-a6e6-24f0302125c4) {'id': '707a4dc3-e294-4d09-a6e6-24f0302125c4', 'created_at': datetime.datetime(2023, 8, 10, 13, 42, 57, 317565), 'updated_at': datetime.datetime(2023, 8, 10, 13, 42, 57, 317569)}", "[Amenity] (5ccd437b-7ee0-4919-b652-c96ea48ef3e2) {'id': '5ccd437b-7ee0-4919-b652-c96ea48ef3e2', 'created_at': datetime.datetime(2023, 8, 10, 13, 43, 3, 162054), 'updated_at': datetime.datetime(2023, 8, 10, 13, 43, 3, 162058)}"] (hbnb)

Example of printing instance of a specific class (for example : Place)

$ ./console.py (hbnb) all Place ["[Place] (268500c2-ce81-428a-be70-e71b2ca61704) {'id': '268500c2-ce81-428a-be70-e71b2ca61704', 'created_at': datetime.datetime(2023, 8, 10, 13, 42, 55, 799743), 'updated_at': datetime.datetime(2023, 8, 10, 13, 42, 55, 799748)}", "[Place] (707a4dc3-e294-4d09-a6e6-24f0302125c4) {'id': '707a4dc3-e294-4d09-a6e6-24f0302125c4', 'created_at': datetime.datetime(2023, 8, 10, 13, 42, 57, 317565), 'updated_at': datetime.datetime(2023, 8, 10, 13, 42, 57, 317569)}"] (hbnb)

* update:
	* Updates an instance based on the class name and id by adding or updating attribute (save the change into the JSON file).
	* Usage: update <class name> <id> <attribute name> "<attribute value>"

$ ./console.py (hbnb) update Place 268500c2-ce81-428a-be70-e71b2ca61704 number_rooms 35 (hbnb)

# Tests

Launch tests:

python3 -m unittest discover tests

All tests should also pass in non-interactive mode: 

$ echo "python3 -m unittest discover tests" | bash
