Coordination

In the previous example, you might have gotten the reverse output.

# hello from plugin2
# hello from plugin1

That's because plug-ins are sorted by the class attribute order, and we didn't change it.

import pyblish.api

class FirstPlugin(pyblish.api.ContextPlugin):
  order = 0

  def process(self, context):
    print("hello")

class SecondPlugin(pyblish.api.ContextPlugin):
  order = 1

  def process(self, context):
    print("world")

pyblish.api.register_plugin(FirstPlugin)
pyblish.api.register_plugin(SecondPlugin)

import pyblish.util
pyblish.util.publish()
# hello
# world

They now run in the expected order.
