This decorator must be used at the module toplevel as follows:: @caching_module_getattr class __getattr__: # The class *must* be named ``__getattr__``. @property # Only properties are taken into account. def name(self): ... The ``__getattr__`` class will be replaced by a ``__getattr__`` function such that trying to access ``name`` on the module will resolve the corresponding property (which may be decorated e.g. with ``_api.deprecated`` for deprecating module globals). The properties are all implicitly cached. Moreover, a suitable AttributeError is generated and raised if no property with the given name exists. __getattr__cSs i|] \}}t|tr||qSr)r.r!)r"nameproprrr s  z*caching_module_getattr..cs,|vr |Stdjd|)Nzmodule z has no attribute )rAttributeErrorrraclsrpropsrrr`s z+caching_module_getattr..__getattr__)rvarsr0 functoolscache)rgr`rrfrcaching_module_getattrs rlc sdur tt|Sfdd}|D]?\}}d}dD]-}||tvrId}|D]}|||}|||_d||d|_t|||q*q|sStd |qd d } t d i} | | | |@} | rot d | i| |_ S)aT Class decorator for defining property aliases. Use as :: @_api.define_aliases({"property": ["alias", ...], ...}) class C: ... For each property, if the corresponding ``get_property`` is defined in the class so far, an alias named ``get_alias`` will be defined; the same will be done for setters. If neither the getter nor the setter exists, an exception will be raised. The alias map is stored as the ``_alias_map`` attribute on the class and can be used by `.normalize_kwargs` (which assumes that higher priority aliases come last).

Calls that fail with a `TypeError` are silently skipped. As soon as a call succeeds, `select_matching_signature` returns its return value. If no function accepts ``*args, **kwargs``, then the `TypeError` raised by the last failing call is re-raised. Callers should normally make sure that any ``*args, **kwargs`` can only bind a single *func* (to avoid any ambiguity), although this is not checked by `select_matching_signature`. Notes ----- `select_matching_signature` is intended to help implementing signature-overloaded functions. In general, such functions should be avoided, except for back-compatibility concerns. A typical use pattern is :: def my_func(*args, **kwargs): params = select_matching_signature( [lambda old1, old2: locals(), lambda new: locals()], *args, **kwargs) if "old1" in params: warn_deprecated(...) old1, old2 = params.values() # note that locals() is ordered. else: new, = params.values() # do things with params which allows *my_func* to be called either with two parameters (*old1* and *old2*) or a single one (*new*). Note that the new signature is given last, so that callers get a `TypeError` corresponding to the new signature if the arguments they passed in do not match any signature. rN) enumerater4r6)funcsrnr9rKfuncrrrselect_matching_signatures, rcCst|d|d|dS)zEGenerate a TypeError to be raised by function calls with wrong arity.z () takes z positional arguments but z were given)r4)ratakesgivenrrr nargs_errorJs rcCs*t|ts tt|}t|d|dS)aL Generate a TypeError to be raised by function calls with wrong kwarg.
