AirBnB clone - The console project

This is the first step towards building our first full web application: the AirBnB clone. This first step is very important because we will use what we build during this project with all other following projects:

Command Interpreter

In this project we are tasked to write a command interpreter to manage our AirBnB objects.

What is Command Interpreter?

Command interpreter or cmd is like a shell It's exactly the same but limited to a specific using, In this project we need a Command interpreter to able to manage the objects of our project like:

Create a new object (ex: a new User or a new Place)
Retrieve an object from a file, a database etc…
Do operations on objects (count, compute stats, etc…)
Update attributes of an object
Destroy an object

How to start it

To start the command interpreter, run the following command in your terminal:

python3 console.py

How to use it

Once the command interpreter is running, you can use the following commands:


create <class>: Creates a new instance of the specified class and saves it to the JSON file.

show <class> <id>: Retrieves the instance of the specified class with the given ID.

all <class>: Retrieves all instances of the specified class, or all instances if no class is specified.

update <class> <id> <attribute> <value>: Updates the attribute of the specified class instance with the given ID.

destroy <class> <id>: Deletes the instance of the specified class with the given ID.

Examples

Here are some examples of how to use the command interpreter:

(hbnb) create User
(hbnb) show User 1234-5678-9012
(hbnb) all User
(hbnb) update User 1234-5678-9012 name "John Doe"
(hbnb) destroy User 1234-5678-9012
(hbnb) quit

Your shell should work like this in interactive mode:

$ ./console.py
(hbnb) help

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

(hbnb) 
(hbnb) 
(hbnb) quit
$

But also in non-interactive mode: (like the Shell project in C)

$ 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) 
$
