Clason

---

Load your classes with json and save it with json or work with python dictionary's

For an example usage look in the folder example

Install

---

Install the package with pip pip install clason

Install with pip + github pip install git+https://github.com/princessmiku/Clason

Basic Setup

---

from clason import Clason

class Student(Clason):
    ...

Example Class

class Student(Clason):
    name: str
    age: int
    address: Address
    email: str = None

How to use?

---

Set a variable with type

name: str, age: int

Supported Types: str, int, list, dict, datetime, float, Clason class

Note: time is a float, current_time: float = time.time()

Values without type are not possible

Set a variable with default value

name: str = "Anna", age: int = 22, date: datetime.datetime = datetime.datetime.now()

if you set a default value, you need only to define a normale variable

Work with List

list: list, list: list[str], list: list[class]

if you set a list, you can define a subtype, as subtype you can use alle regular supported types.

Note: If you not define a subtype, it could be make problems with datetime and a clason classes because they are handled differently

Work with Dictionary

dict: dict[str, any], dict[str, str]

if you set a list, you can define a subtype, as subtype you can use alle regular supported types. if you not want to define a subtype you need to write any, else it could make problems

Work with a Clason class

myClass: ClassWithClasson

It's possible to set a type as a Clason class, if you have another class that extends Clason, for example a Address class. Clason.

Clason will then initalize these in the same way as all other clason classes. This is also possible to inherit more often

Functions

---

On Class initialization

It is possible to write your own init method during the initialization of a class, before and after.

Setup

from clason import Clason
class Student(Clason):
    name: str

    def clason_on_init_start(self):
        # starts before the loading process
        ... # your code
    def clason_on_init_end(self):
        # starts at the end of the loading process
        ... # your code

Class loading

If you want to load your json file or a python dictionary do this

Load - Single

Load a single json/python dictionary

from clason import Clason
class Student(Clason):
    name: str

anna = Student.clason_load("anna.json") # load from a json file

anna = Student.clason_loads("...") # load from a json string

anna = Student.clason_load_d({...}) # load from a python dictionary

Load - Multi

Load a list of data from a json/python dictionary

A multi load function need a target class

Its return a list with the loaded target class

from clason import Clason, load_many, loads_many, load_many_d

class Student(Clason):
    name: str

students = load_many('students.json', Student)  # load from a json file

students = loads_many("...", Student)  # load from a json string

students = load_many_d([{},...], Student) # load from a python dictionary

Class saving

If you want to save your class in a json file or a python dictionary do this

Indent is optional, try it out what it does, it's except an integer

Save - Single

Save a single class in a json/python dictionary

from clason import Clason
class Student(Clason):
    name: str
    
    def __init__(self, name):
        self.name = name
anna = Student("Anna")
anna.clason_dump("anna.json", indent=2) # save in a json file
anna_str = anna.clason_dumps(indent=2) # save in a json string, it return a string

anna_dict = anna.clason_dump_d() # save in a python dictionary, it returns a python dictionary

Save - Multi

Save a list of classes in a json/python dictionary

A multi save need a list with the classes

from clason import Clason, dump_many, dumps_many, dump_many_d


dump_many('students.json', [anna, ...], indent=2) # save in a json file

students_str = dumps_many([anna, ...], indent=2)  # save in a json string, it return a string

students_dict = dump_many_d([anna, ...]) # save in a python dictionary, it returns a list with python dictionarys
