Example

Let's create an empty class, which will automatically receive special attributes from the decorating ClassorClass, specially the NameStr, that should be the ClassStr without the TypeStr in the end.

#ImportModules
import ShareYourSystem as SYS
from ShareYourSystem.Standards.Interfacers import Loader

#Definition of an instance Loader and make it find the current dir
MyLoader=Loader.LoaderClass().file('MyFile.txt','w')
MyLoader.FiledHardVariable.write('hello')
MyLoader.FiledHardVariable.close()
MyLoader.load()

#Definition the AttestedStr
SYS._attest(
    [
        'MyLoader is '+SYS._str(MyLoader,
            **{'RepresentingAlineaIsBool':False}
        )
    ]
) 

#Print

>>>


*****Start of the Attest *****

MyLoader is < (LoaderClass), 4540264912>
   /{ 
   /  '<New><Instance>IdInt' : 4540264912
   /  '<Spe><Class>LoadingFormatStr' : txt
   /  '<Spe><Instance>LoadedReadVariable' : hello
   /}

*****End of the Attest *****
