Function Details

class_moved(new_class, old_name=None, message=None)

source code

nice wrapper around class_renamed when a class has been moved into
another module

class_renamed(old_name, new_class, message=None)

source code

automatically creates a class which fires a DeprecationWarning
when instantiated.

>>> Set = class_renamed('Set', set, 'Set is now replaced by set')
>>> s = Set()
sample.py:57: DeprecationWarning: Set is now replaced by set
  s = Set()
>>>

moved(modpath, objname)

source code

use to tell that a callable has been moved to a new module.

It returns a callable wrapper, so that when its called a warning is printed
telling where the object can be found, import is done (and not before) and
the actual object is called.

NOTE: the usage is somewhat limited on classes since it will fail if the
wrapper is use in a class ancestors list, use the `class_moved` function
instead (which has no lazy import feature though).
