0x00. AirBnB clone - The console

Creation of a command interpreter to manage the hbnb projects

Description of the project

This is the first step towards building your first full web application: the AirBnB clone. The aim of the project is to deploy a replica of the Airbnb Website using my server. The final version of this project will have:

• A command interpreter to manipulate data without a visual interface, like a shell (for development and debugging)
• A website (front-end) with static and dynamic functionalities
• A comprehensive database to manage the backend functionalities
• An API that provides a communication interface between the front and backend of the system.

Resources

• Videos showing examples of how various parts of the project work, listed below:
• HBNB videos
• Holberton Airbnb overview
• The Airbnb Console
• Airbnb ORM
• Airbnb API
• Final product
• Other resource
• cmd module
  • packages concept page
  • Python packages
  • uuid module
  • datetime
  • unittest module
  • args/kwargs
  • Python test cheatsheet
  • AirBnB website.

$ ./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)
