Now that you know how to arrange plug-ins, let's have a look at how to manage the control flow of publishing.

import pyblish.api

class MyPlugin(pyblish.api.ContextPlugin):
  hosts = ["maya"]

  def process(self, context):
    from maya import cmds
    cmds.headsUpMessage("Hello from Pyblish")

pyblish.api.register_plugin(MyPlugin)

import pyblish.util
pyblish.util.publish()
# Hello from Pyblish

hosts is a requirement attribute and limits plug-ins to a particular scenario.

In this case, the plug-in will only run when publishing from within Autodesk Maya. These are some examples of available values for the hosts attribute.

• python

• maya

• houdini

• nuke

• modo

• unknown

You can register your own host, if for example you would like to extend Pyblish for use in additional software, by using register_host().

import pyblish.api
pyblish.api.register_host("myhost")
