The command interpreter 🕹️

In order to manage the objects of our program, we create an environment where we can use and execute specific commands that will allow us to manage our program in a more efficient way,

Interactive mode: 💻

➜  AirBnB_clone git:(main) ✗ ./console.py 
(hbnb)help

Documented commands (type help <topic>):
========================================
EOF  User  all  create  destroy  help  quit  show

(hbnb)
(hbnb)
(hbnb)
(hbnb)quit
➜  AirBnB_clone git:(main) ✗

##In non-interactive mode: 🖥️

➜  AirBnB_clone git:(main) ✗ echo "help" | ./console.py
(hbnb)
Documented commands (type help <topic>):
========================================
EOF  User  all  create  destroy  help  quit  show

(hbnb)%                                                                     
➜  AirBnB_clone git:(main) ✗

Usage of commands

Syntax : quit

Command to exit the program

➜  AirBnB_clone git:(main) ✗ ./console.py 
(hbnb)
(hbnb)quit
➜  AirBnB_clone git:(main) ✗

Syntax : EOF

Command to exit the program

➜  AirBnB_clone git:(main) ✗ ./console.py
(hbnb)
(hbnb)EOF
➜  AirBnB_clone git:(main) ✗

Syntax : create

Creates a new instance of BaseModel, saves it (to the JSON file) and prints the id.

➜  AirBnB_clone git:(main) ✗ ./console.py
(hbnb)
(hbnb)create
** class name missing **
(hbnb)create MyModel
** class does not exist **
(hbnb)create BaseModel
.9fbd3cc9-3e0b-411b-ac1b-5a8e01b64a1d
(hbnb)
(hbnb)

Syntax : show

Prints the string representation of an instance based on the class name and id.

➜  AirBnB_clone git:(main) ✗ ./console.py
(hbnb)
(hbnb)show
** class name missing **
(hbnb)show MyModel
** class doesnt exist **
(hbnb)show BaseModel
** instance id missing **
(hbnb)show BaseModel 121212
** no instance found **
(hbnb)
(hbnb)show 9fbd3cc9-3e0b-411b-ac1b-5a8e01b64a1d
** class doesnt exist **
(hbnb)show BaseModel 9fbd3cc9-3e0b-411b-ac1b-5a8e01b64a1d
[BaseModel] (9fbd3cc9-3e0b-411b-ac1b-5a8e01b64a1d) {'created_at': datetime.datetime(2021, 11, 13, 23, 5, 18, 456036), 'id': '9fbd3cc9-3e0b-411b-ac1b-5a8e01b64a1d', 'updated_at': datetime.datetime(2021, 11, 13, 23, 5, 18, 456053)}
(hbnb)

Syntax : destroy

Deletes an instance based on the class name and id (save the change into the JSON file).

➜  AirBnB_clone git:(main) ✗ ./console.py
(hbnb)
(hbnb)destroy
** class name missing **
(hbnb)destroy MyModel
** class doesnt exist **
(hbnb)destroy BaseModel
** instance id missing **
(hbnb)destroy BaseModel 121212
** no instance found **
(hbnb)destroy BaseModel 9fbd3cc9-3e0b-411b-ac1b-5a8e01b64a1d
(hbnb)

Syntax : all

Prints all string representation of all instances based or not on the class name.

➜  AirBnB_clone git:(main) ✗ ./console.py
(hbnb)
(hbnb)all BaseModel
[BaseModel] (d4f94723-c724-4803-a92c-342a69dee1d7) {'created_at': datetime.datetime(2021, 11, 12, 20, 21, 40, 173122), 'id': 'd4f94723-c724-4803-a92c-342a69dee1d7', 'my_number': 89, 'name': 'My_First_Model', 'updated_at': datetime.datetime(2021, 11, 12, 20, 21, 40, 173128)}
