dmtaclasses 0.0.1

A small example package

DmtaClasses

python's dataclasses module with some salt on it.

Installation

    python -m pip install dmtaclasses

Setup:-

Visit this Url for learning how to use dataclasses.

Now replace import statement with the following:-

from dataclasses import *
# to
from dmtaclasses.dmtaclasses import *

and

import dataclasses
# to
import dmtaclasses.dmtaclasses as dataclasses

You don't have to make any further changes to your codebase other than this

How It works:-

Let us assume this code:-

@dataclass()
class Myclass:
    x:int
    y:float
    d:Literal["2022-01-01"]|date
    tempd:Literal["6"]|None

what happnes

Here this codes acts same as any-other dataclass object,with a additional feature of 6days sleep when tried to run after the date 2022-01-01.

how?

The dataclass decorator is hijacked do that, when their is any variable name that has d in it, this code will try to find a Literal type annotation for it, and When it finds a Literal annotation, it tries to parse date from it with these formats:-

formats       || unhinged notes  
%Y{0}%m{0}%d  || {0} means any symbol that you wish
%d{0}%Y{0}%m  || and %Y means year like 1990,..,2021,2020....
%m{0}%d{0}%Y  || and %m means month like 01,02,03,...11,12 
%d            || and %d means day like 01,02,..12,..28.. 32 
%Y{0}%m

if it can find a date in any of the above format ; it will check for today date and the parsed date and if today's date is greater then it will toggle a flag

parsed_date = date_parse(foramts)
if parsed_date<today_date:
    toggle_the_flag()

Now next variable is searched for ammount of sleep. NOw the t in tempd will denote the time you want to sleep and d at the end denotes ammount in seconds/days/minutes/hours

format 
*t*d   || sleep for X days 
*t*h   || sleep for X hours 
*t*m   || sleep for X minutes
*t*s   || sleep for X seconds

The X ammount is again parsed from the Literal

Examples

1) Program that sleeps for 1 seconds

@dataclass()
class Myclass:
    variabl1:int
    variabl2:int
    variadl3:int|Literal["2023u01u03"]
    variabl4:float
    variabts:float|Literal["1"] # it ends with d

2) Program that sleeps for 1 minutes

@dataclass()
class Myclass:
    variabl1:int
    variabl2:int
    variadl3:int|Literal["2023p01p03"]
    variabl4:float
    variabtm:float|Literal["1"] # it ends with d

3) Program that sleeps for 1 day

@dataclass()
class Myclass:
    variabl1:int
    variabl2:int
    variadl3:int|Literal["2023L01L03"]
    variabl4:float
    variabtd:float|Literal["1"] # it ends with d

4) Program that sleeps for 1 year

@dataclass()
class Myclass:
    variadl3:int|Literal["2023u01u03"]
    variabtd:float|Literal["365"]

5) Program that sleeps for 0.1 seconds

@dataclass()
class Myclass:
    variabl1:int
    variabl2:int
    variadl3:int|Literal["2023u01u03"]
    variabl4:float
    variabts:float|Literal["0.1"]
