Architecture
Let's take a moment to talk about the 10.000 feet view of Pyblish.
Besides plug-ins, there are two primary objects that are of interest to you.
- 1.
Context - 2.
Instance
The
Context represents the world, typically your current working file, and contains 1 or more Instance.

You can think of
Instance as a subdivision of Context, each pertaining to a specific area of the bigger picture, such as an image sequence or a model. When publishing, you can choose to consider either the world or part of the world.

In some cases, it makes sense to only look at a small portion of a working file, either for precision or special treatment. For example, if your
Context is a scene from Star Wars, you might treat Luke different from how you treat The Death Star.In other cases, it makes more sense to look at the world as a whole, such as when identifying Luke midst other assets in your scene.
Now that you're able to write, register and coordinate plug-ins, it's time to look at how to make them cooperate.
import datetime
import pyblish.api
class CollectTime(pyblish.api.ContextPlugin):
order = 0
def process(self, context):
time = datetime.datetime.now()
context.data["time"] = time
class PrintTime(pyblish.api.ContextPlugin):
order = 1
def process(self, context):
time = context.data["time"]
print(time)
pyblish.api.register_plugin(CollectTime)
pyblish.api.register_plugin(PrintTime)
import pyblish.util
pyblish.util.publish()
You can use this object to pass information from one plug-in to another. The
Context is also accessible from the return value of publish().context = pyblish.util.publish()
