Expose class members as Fabric tasks
Fabric has class-based tasks but they are limited: Task class represents a single task.
This module make it possible to have class-based Fabric task sets.
pip install fabric-taskset
TaskSet is a class that can expose its methods as Fabric tasks.
# my_lib/say.py from taskset import TaskSet, task class SayBase(TaskSet): def say(self, what): raise NotImplemented() @task(default=True, alias='hi') def hello(self): self.say('hello') class EchoSay(SayBase): def say(self, what): local('echo ' + what) instance = EchoSay() instance.expose_to_current_module() # fabfile.py from mylib import say
and then e.g.:
$ fab say.hi hello
taskset.task is a decorator declaring the wrapped method to be task. It acceps the same arguments as fabric.decorators.task so use it on methods just like fabric’s decorator is used on functions.
https://github.com/ramusus/fabriclassed is a very similar app. At the time of writing it is focused on old-style Fabric tasks and has a small deployment framework included.
In order to feed my NIH syndrome I create Fabric-taskset which exposes new-style Fabric tasks, provides slightly different API and doesn’t have extra goodies.
