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")
