potc_typing

A simple demo of potc plugin, which can make the dict prettier.

Installation

You can simply install it with pip command line from the official PyPI site.

pip install potc-typing

Or install this plugin by source code

git clone https://github.com/potc-dev/potc-typing.git
cd potc-typing
pip install .

Effect show

We prepare a python script named test_data.py, like this

import types
from typing import List, Union, Tuple, Callable, Dict

t_lst = List[int]
t_tps = Union[Tuple[int, ...], int]
t_func = Callable[[Union[str, int, None], int], Dict[str, types.FunctionType]]

Before the installation mentioned above, we try to export the b in test_data.py by the following CLI command

potc export -v 'test_data.t_*'

We can get this dumped source code.

from typing import _GenericAlias

from potc.supports import typed_object

__all__ = ['t_func', 't_lst', 't_tps']
t_func = typed_object(
    _GenericAlias,

)

BUT, after the installation, we try the CLI command which is exactly the same again, we get the new code

import types
from typing import Callable, Dict, List, Optional, Tuple, Union

__all__ = ['t_func', 't_lst', 't_tps']
t_func = Callable[[Optional[Union[str, int]], int], Dict[str, types.LambdaType]]
t_lst = List[int]
t_tps = Union[Tuple[int, ...], int]

That is all of this plugin. When you need to build your own plugin, maybe this demo can help you 😄.
