types
def types(*deptypes, **kwargs)
Declare that the decorated function or method expects args of the given types. Use square brackets to request all instances of a type as a list. Use this kwarg to declare the type of result returned by a factory.
DI Objects
class DI()
add
def add(obj)
Register the given class, factory or instance.
all
def all(type)
Return all objects of the given type, instantiating them and collaborators if necessary.
__call__
def __call__(clazz)
Return unique object of the given type, instantiating it and its collaborators if necessary.
__exit__
def __exit__(*exc_info)
Discard all instances created by this container, calling dispose if they have it.
diapyr.start
diapyr.util
innerclass
def innerclass(cls)
An instance of the decorated class may access its enclosing instance via self.
singleton
def singleton(t)
The decorated class is replaced with a no-arg instance.
invokeall
def invokeall(callables)
Invoke every callable, even if one or more of them fail. This is mostly useful for synchronising with futures. If all succeeded return their return values as a list, otherwise raise all exceptions thrown as a chain.
bfs
def bfs(keys)
Breadth-first search starting with the given iterable of keys, intended to be used as a decorator.
If a function is decorated it should take an info object and key, and yield subsequent keys.
If a class is decorated, a new instance of it is used as info object:
The class should have a newdepth method that will be called before each depth, and a process method that takes a key and yields subsequent keys as in the function case.
The info object is kept updated with the list of currentkeys, current depth and the set of donekeys.
Note that the first currentkeys (depth 0) is exactly the passed in keys iterable, subsequent currentkeys will be non-empty lists.
The process function is only invoked for keys that have not yet been processed, i.e. unique keys.
When finished the decorated function/class is replaced with the last state of the info object.
setuphacks
getsetupkwargs
def getsetupkwargs(setuppath, fields)
Extract the kwargs passed to setup at the given path (typically some setup.py) that have names in the given fields.
