## General
# Command Line Interpreter for Airbnb Clone - The Console
This command line interpreter is designed for an Airbnb clone application. It allows users to interact with the application's backend through a console, where they can create and manage instances of the application's classes.
## How to Use
To start the console, run the script `console.py`. This will start the command line interpreter, and the prompt `(hbnb)` will be displayed. This prompt indicates that the console is ready to accept user input.
The following commands are available:
* `create`: Creates a new instance of a class.
* `show`: Prints the string representation of an instance.
* `destroy`: Deletes an instance based on the class name and ID.
* `all`: Prints all string representations of all instances, or all instances of a particular class.
* `update`: Updates an instance based on the class name and ID.
* `count`: Counts the instances of a class.
* `EOF`: Exits the console.
* `quit`: Exits the console.
The syntax for each command is as follows:
* `create `: Creates a new instance of the specified class.
* `show `: Prints the string representation of the specified instance.
* `destroy `: Deletes the specified instance.
* `all`: Prints the string representations of all instances.
* `all `: Prints the string representations of all instances of the specified class.
* `update ""`: Updates the specified instance with the specified attribute value.
* `count `: Counts the instances of the specified class.
## Requirements
### Python Scripts
* Allowed editors: `vi`, `vim`, `emacs`
* All your files will be interpreted/compiled on Ubuntu 20.04 LTS using python3 (version 3.8.5)
* All your files should end with a new line
* The first line of all your files should be exactly `#!/usr/bin/python3`
* A `README.md` file, at the root of the folder of the project, is mandatory
* Your code should use the pycodestyle (version `2.8.*`)
* All your files must be executable
* The length of your files will be tested using `wc`
* All your modules should have a documentation (`python3 -c 'print(__import__("my_module").__doc__)'`)
* All your classes should have a documentation (`python3 -c 'print(__import__("my_module").MyClass.__doc__)'`)
* All your functions (inside and outside a class) should have a documentation (`python3 -c 'print(__import__("my_module").my_function.__doc__)'` and `python3 -c 'print(__import__("my_module").MyClass.my_function.__doc__)'`)
* A documentation is not a simple word, it’s a real sentence explaining what’s the purpose of the module, class or method (the length of it will be verified)
### Python Unit Tests
* Allowed editors: `vi`, `vim`, `emacs`
* All your files should end with a new line
* All your test files should be inside a folder [tests](./tests)
* You have to use the [unittest](https://docs.python.org/3.4/library/unittest.html#module-unittest) module
* All your test files should be python files (extension: `.py`)
* All your test files and folders should start by `test_`
* Your file organization in the tests folder should be the same as your project
* e.g., For `models/base_model.py`, unit tests must be in: `tests/test_models/test_base_model.py`
* e.g., For `models/user.py`, unit tests must be in: `tests/test_models/test_user.py`
* All your tests should be executed by using this command: `python3 -m unittest discover tests`
* You can also test file by file by using this command: `python3 -m unittest tests/test_models/test_base_model.py`
* All your modules should have a documentation (`python3 -c 'print(__import__("my_module").__doc__)'`)
* All your classes should have a documentation (`python3 -c 'print(__import__("my_module").MyClass.__doc__)'`)
* All your functions (inside and outside a class) should have a documentation (`python3 -c 'print(__import__("my_module").my_function.__doc__)'` and `python3 -c 'print(__import__("my_module").MyClass.my_function.__doc__)'`)
## More Info
### Execution
Your shell should work like this in interactive mode:
```
$ ./console.py
(hbnb) help
Documented commands (type help ):
========================================
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 ):
========================================
EOF help quit
(hbnb)
$
$ cat test_help
help
$
$ cat test_help | ./console.py
(hbnb)
Documented commands (type help ):
========================================
EOF help quit
(hbnb)
$
```
All tests should also pass in non-interactive mode: `$ echo "python3 -m unittest discover tests" | bash`
## Tasks
0.[README](./README.md), [AUTHORS](./AUTHORS)
* Write a `README.md`:
* description of the project
* description of the command interpreter:
* how to start it
* how to use it
* examples
* You should have an AUTHORS file at the root of your repository, listing all individuals having contributed content to the repository. For format,
reference [Docker’s AUTHORS page](https://github.com/moby/moby/blob/master/AUTHORS)
[1. Be pycodestyle compliant!](./AirBnB_clone)
Write beautiful code that passes the `pycodestyle` checks.
[2. Unittests](./tests)
All files, classes, functions must be tested with unit tests.
```

*Note that this is just an example, the number of tests you create can be different from the above example.*
**Warning**:
Unit tests must also pass in non-interactive mode:
```

[3. BaseModel](./models/base_model.py)
Write a class `BaseModel` that defines all common attributes/methods for other classes:
* `models/base_model.py`
* Public instance attributes:
* `id`: string - assign with an `uuid` when an instance is created:
* you can use `uuid.uuid4()` to generate unique `id` but don’t forget to convert to a string
* the goal is to have unique `id` for each `BaseModel`
* `created_at`: datetime - assign with the current datetime when an instance is created
* `updated_at`: datetime - assign with the current datetime when an instance is created and it will be updated every time you change your object
* `__str__`: should print: `[] () `
* Public instance methods:
* save(self): updates the public instance attribute `updated_at` with the current datetime
* to_dict(self): returns a dictionary containing all `keys/values` of `__dict__` of the instance:
* by using `self.__dict__`, only instance attributes set will be returned
* a key `__class__` must be added to this dictionary with the class name of the object
* `created_at` and `updated_at` must be converted to string object in ISO format:
* format: `%Y-%m-%dT%H:%M:%S.%f` (`ex: 2017-06-14T22:31:03.285259`)
* you can use `isoformat()` of `datetime` object
* This method will be the first piece of the serialization/deserialization process: create a dictionary representation with “simple object type” of our `BaseModel`
```

[4. Create BaseModel from dictionary](./models/base_model.py)
Previously we created a method to generate a dictionary representation of an instance (method `to_dict()`).
Now it’s time to re-create an instance with this dictionary representation.
```
-> to_dict() -> ->
```
Update `models/base_model.py`:
* `__init__(self, *args, **kwargs)`:
* Use `*args, **kwargs` arguments for the constructor of a `BaseModel`.
* `*args` won’t be used
* if `kwargs` is not empty:
* each key of this dictionary is an attribute name (**Note** `__class__` from `kwargs` is the only one that should not be added as an attribute. See the example output, below)
* each value of this dictionary is the value of this attribute name
* **Warning**: `created_at` and `updated_at` are strings in this dictionary, but inside the `BaseModel` instance is working with `datetime` object. Convert these strings into `datetime` object. Tip: you know the string format of these datetime
* otherwise:
* create `id` and `created_at` as you did previously (new instance)
```

[5. Store first object](./models/engine/file_storage.py)
Now recreate a `BaseModel` from another one by using a dictionary representation:
```
-> to_dict() -> ->
```
It’s great but it’s still not persistent: every time you launch the program, you don’t restore all objects created before… The first way is to save these objects to a file.
Writing the dictionary representation to a file won’t be relevant:
* Python doesn’t know how to convert a string to a dictionary (easily)
* It’s not human readable
* Using this file with another program in Python or other language will be hard.
So, convert the dictionary representation to a JSON string. JSON is a standard representation of a data structure. With this format, humans can read and all programming languages have a JSON reader and writer.
Now the flow of serialization-deserialization will be:
```
-> to_dict() -> -> JSON dump -> -> FILE -> -> JSON load -> ->
```
Magic right?
Terms:
* **simple Python data structure**: Dictionaries, arrays, number and string. ex: `{ '12': { 'numbers': [1, 2, 3], 'name': "John" } }`
* **JSON string representation**: String representing a simple data structure in JSON format. ex: `'{ "12": { "numbers": [1, 2, 3], "name": "John" } }'`
Write a class `FileStorage` that serializes instances to a JSON file and deserializes JSON file to instances:
* `models/engine/file_storage.py`
* Private class attributes:
* `__file_path`: string - path to the JSON file (ex: `file.json`)
* `__objects`: dictionary - empty but will store all objects by `.id` (ex: to store a `BaseModel` object with `id=12121212`, the key will be `BaseModel.12121212`)
* Public instance methods:
* `all(self)`: returns the dictionary `__objects`
* `new(self, obj)`: sets in `__objects` the obj with key `.id`
* `save(self)`: serializes `__objects` to the JSON file (path: `__file_path`)
* `reload(self)`: deserializes the JSON file to `__objects` (only if the JSON file (`__file_path`) exists ; otherwise, do nothing. If the file doesn’t exist, no exception should be raised)
Update `models/__init__.py`: to create a unique `FileStorage` instance for your application
* import `file_storage.py`
* create the variable storage, an instance of `FileStorage`
* call `reload()` method on this variable
Update `models/base_model.py`: to link your `BaseModel` to `FileStorage` by using the variable `storage`
* import the variable `storage`
* in the method `save(self)`:
* call `save(self)` method of storage
* `__init__(self, *args, **kwargs)`:
* if it’s a new instance (not from a dictionary representation), add a call to the method `new(self)` on `storage`
```

[6. Console 0.0.1](./console.py)
Write a program called `console.py` that contains the entry point of the command interpreter:
* You must use the module `cmd`
* Your class definition must be: `class HBNBCommand(cmd.Cmd):`
* Your command interpreter should implement:
* `quit` and `EOF` to exit the program
* `help` (this action is provided by default by cmd but you should keep it updated and documented as you work through tasks)
* a custom prompt: `(hbnb)`
* an empty line + `ENTER` shouldn’t execute anything
* Your code should not be executed when imported
**Warning**:
You should end your file with:
```
if __name__ == '__main__':
HBNBCommand().cmdloop()
```

[7. Console 0.1](./console.py)
Update command interpreter (`console.py`) to have these commands:
* `create`: Creates a new instance of `BaseModel`, saves it (to the JSON file) and prints the `id`. Ex: `$ create BaseModel`
* If the class name is missing, print ** class name missing ** (ex: $ create)
* If the class name doesn’t exist, print `** class doesn't exist **` (ex: `$ create MyModel`)
* `show`: Prints the string representation of an instance based on the class name and `id`. Ex: `$ show BaseModel 1234-1234-1234.`
* If the class name is missing, print `** class name missing **` (ex: `$ show`)
* If the class name doesn’t exist, print `** class doesn't exist **` (ex: `$ show MyModel`)
* If the `id` is missing, print `** instance id missing **` (ex: `$ show BaseModel`)
* If the instance of the class name doesn’t exist for the `id`, print `** no instance found **` (ex: `$ show BaseModel 121212`)
* `destroy`: Deletes an instance based on the class name and `id` (save the change into the JSON file). Ex: `$ destroy BaseModel 1234-1234-1234.`
* If the class name is missing, print `** class name missing **` (ex: `$ destroy`)
* If the class name doesn’t exist, print `** class doesn't exist **` (ex:`$ destroy MyModel`)
* If the `id` is missing, print `** instance id missing **` (ex: `$ destroy BaseModel`)
* If the instance of the class name doesn’t exist for the `id`, print `** no instance found **` (ex: `$ destroy BaseModel 121212`)
* `all`: Prints all string representation of all instances based or not on the class name. Ex: `$ all BaseModel` or `$ all`.
* The printed result must be a list of strings
* If the class name doesn’t exist, print `** class doesn't exist **` (ex: `$ all MyModel`)
* `update`: Updates an instance based on the class name and `id` by adding or updating attribute (save the change into the JSON file). Ex: `$ update BaseModel 1234-1234-1234 email "aibnb@mail.com"`.
* Usage: `update ""`
* Only one attribute can be updated at the time
* You can assume the attribute name is valid (exists for this model)
* The attribute value must be casted to the attribute type
* If the class name is missing, print `** class name missing **` (ex: `$ update`)
* If the class name doesn’t exist, print `** class doesn't exist **` (ex: `$ update MyModel`)
* If the `id` is missing, print `** instance id missing **` (ex: `$ update BaseModel`)
* If the instance of the class name doesn’t exist for the `id`, print `** no instance found **` (ex: `$ update BaseModel 121212`)
* If the attribute name is missing, print `** attribute name missing **` (ex: `$ update BaseModel existing-id`)
* If the value for the attribute name doesn’t exist, print `** value missing **` (ex: `$ update BaseModel existing-id first_name`)
* All other arguments should not be used (Ex: `$ update BaseModel 1234-1234-1234 email "aibnb@mail.com" first_name "Betty" = $ update BaseModel 1234-1234-1234 email "aibnb@mail.com"`)
* `id`, `created_at` and `updated_at` cant’ be updated. You can assume they won’t be passed in the update command
* Only “simple” arguments can be updated: `string`, `integer` and `float`. You can assume nobody will try to update list of ids or `datetime`
Let’s add some rules:
* You can assume arguments are always in the right order
* Each arguments are separated by a space
* A string argument with a space must be between double quote
* The error management starts from the first argument to the last one

[8. First User](./models/user.py)
Write a class `User` that inherits from `BaseModel`:
* `models/user.py`
* Public class attributes:
* `email`: string - empty string
* `password`: string - empty string
* `first_name`: string - empty string
* `last_name`: string - empty string
Update `FileStorage` to manage correctly serialization and deserialization
of User.
Update command interpreter (`console.py`) to allow `show`, `create`, `destroy`,
`update` and `all` used with `User`.

* Public class attributes:
* `name`: string - empty string
* `City` (`models/city.py`):
* Public class attributes:

[17. Unittests for the Console!](./tests/test_console.py)
Write all unittests for `console.py`, all features!
For testing the console, you should “intercept” STDOUT of it.
```
with patch('sys.stdout', new=StringIO()) as f:
HBNBCommand().onecmd("help show")
```
Otherwise, you will have to re-write the console by replacing `precmd` by `default`.
