cdZdZdS)z1py2/py3 metaclass utility, from jinja2 via Bokeh.cFi}Gfdd}|dd|S)aAdd metaclasses in both Python 2 and Python 3. Function from jinja2/_compat.py. License: BSD. Use it like this:: class BaseForm(object): pass class FormType(type): pass class Form(with_metaclass(FormType, BaseForm)): pass This requires a bit of explanation: the basic idea is to make a dummy metaclass for one level of class instantiation that replaces itself with the actual metaclass. Because of internal type checks we also need to make sure that we downgrade the custom metaclass for one level to something closer to type (that's why __call__ and __init__ comes back from type etc.). This has the advantage over six.with_metaclass of not introducing dummy classes into the final MRO. c8eZdZejZejZfdZdS)!with_metaclass..metaclassc\|t||d|S||S)N)type__new__)clsname this_basesdbasesmetas Clib/python3.11/site-packages/anaconda_project/internal/metaclass.pyrz)with_metaclass..metaclass.__new__+s7 6||Cr15554eQ'' 'N)__name__ __module__ __qualname__r__call____init__r)r rsr metaclassr'sA== ( ( ( ( ( ( ( (rrtemporary_classNr)rr emptyrs`` rwith_metaclassr s[4 E((((((((D((( 9&e 4 44rN)__doc__rrrrrs&87%5%5%5%5%5r
