hookimpl = pluggy.HookimplMarker("myproject")
class MySpec(object):
"""A hook specification namespace.
"""
@hookspec
def myhook(self, arg1, arg2):
"""My special little hook that you can customize.
"""
class Plugin_1(object):
"""A hook implementation namespace.
"""
@hookimpl
def myhook(self, arg1, arg2):
print("inside Plugin_1.myhook()")
return arg1 + arg2
class Plugin_2(object):
"""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)
