Decrator utils

[dev0Guy]

User description

rewrite some of the decrator utils.
By converting for loops into list, dict comprehension , I've a lot of wrapped try, exception section inside the loop with re-raise, I've removed them (there is no unique logic inside the exception block).

Original

defget_non_dependencies_params(cls):
source=inspect.getsource(cls.__init__).strip()
tree=ast.parse(source)
non_dependencies= {}
fornodeinast.walk(tree):
ifisinstance(node, ast.Attribute):
non_dependencies[node.attr] =node.value.idreturnnon_dependencies

Changed

defget_non_dependencies_params(cls: Type):
source=inspect.getsource(cls.__init__).strip()
tree=ast.parse(source)
return {
node.attr: node.value.idfornodeinast.walk(tree)
ifisinstance(node, ast.Attribute)
}

Forthermore, I've seen duplicate code inside get_instance_variables where the dependencies is already written inside parse_dependencies.

dependencies=set(
param.nameforparamininspect.signature(cls.__init__).parameters.values()
ifparam.annotation!=param.emptyandgetattr(param.annotation, "__injectable__", False)
)

defparse_dependencies(cls):
signature=inspect.signature(cls.__init__)
dependecies= {}
forparaminsignature.parameters.values():
try:
if (
param.annotation!=param.emptyandhasattr(param.annotation, "__dict__")
andINJECTABLE_TOKENinparam.annotation.__dict__
):
dependecies[param.name] =param.annotationexceptExceptionase:
raiseereturndependecies

I didn't understand why the need to check only object ( not including inherited attributes) however I assume a usage and created another argument for parse_dependencies to decide which check to activate.
and got:

defparse_dependencies(cls: Type, check_inherited: bool=False) ->Dict[str, Type]:
""" Returns: mapping of injectable parameters name to there annotation """signature=inspect.signature(cls.__init__)
filter_by= (
_check_injectable_inheritedifcheck_inheritedelse_check_injectable_not_inherited
)
params: Iterable[inspect.Parameter] =filter(filter_by, signature.parameters.values())
return {param.name: param.annotationforparaminparams}

Below is a concise technical summary of the changes proposed in this PR:

Refactors and optimizes utility functions in the nest/core/decorators/utils.py file. Converts for loops into list and dictionary comprehensions, removes unnecessary try-except blocks, and introduces type hints. Adds new helper functions to improve code readability and maintainability. Modifies the parse_dependencies function to handle both inherited and non-inherited injectable attributes.
