This is the core framework used by the `pytest`_, `tox`_, and `devpi`_ projects.
|
|
|
|
Please `read the docs`_ to learn more!
|
|
|
|
A definitive example
|
|
====================
|
|
.. code-block:: python
|
|
|
|
import pluggy
|
|
|
|
hookspec = pluggy.HookspecMarker("myproject")
|
|
hookimpl = pluggy.HookimplMarker("myproject")
|
|
|
|
|
|
class MySpec:
|
|
"""A hook specification namespace."""
|
|
|
|
@hookspec
|
|
def myhook(self, arg1, arg2):
|
|
"""My special little hook that you can customize."""
|
|
|
|
|
|
class Plugin_1:
|
|
"""A hook implementation namespace."""
|
|
|
|
@hookimpl
|
|
def myhook(self, arg1, arg2):
|
|
print("inside Plugin_1.myhook()")
|
|
return arg1 + arg2
|
|
|
|
|
|
class Plugin_2:
|
|
"""A 2nd hook implementation namespace."""
|
|
|
|
@hookimpl
|
|
def myhook(self, arg1, arg2):
|
|
print("inside Plugin_2.myhook()")
|
|
return arg1 - arg2
|
|
|
|
|
|
# create a manager and add the spec
|
|
pm = pluggy.PluginManager("myproject")
|
|
pm.add_hookspecs(MySpec)
|
|
|
|
# register plugins
|
|
pm.register(Plugin_1())
|
|
pm.register(Plugin_2())
|
|
|
|
# call our ``myhook`` hook
|
|
results = pm.hook.myhook(arg1=1, arg2=2)
|
|
print(results)
|
|
|
|
|
|
Running this directly gets us::
|
|
|
|
$ python docs/examples/toy-example.py
|
|
inside Plugin_2.myhook()
|
|
inside Plugin_1.myhook()
