Pyblish By Example

Report I

Publishing is about finding problems and the only way to find them is by bringing them to the surface, to visualise them. So in this example, we'll have a look at how you can do just that.
We can use the results produced during publishing to pretty-print ourselves a report of how things went. This is what we will be producing in this example.
Success Plug-in -> Instance
1 CollectCaptainAmerica -> None
0 ValidateCaptainAmerica -> Captain America
Let's dive into the plug-ins now.
import pyblish.api
class CollectCaptainAmerica(pyblish.api.ContextPlugin):
order = pyblish.api.CollectorOrder
def process(self, context):
context.create_instance("Captain America", isHero=False)
class ValidateCaptainAmerica(pyblish.api.InstancePlugin):
order = pyblish.api.ValidatorOrder
def process(self, instance):
# Any raised exception will mark a plug-in as failed
assert"isHero") == True, "%s must be a hero" % instance
import pyblish.util
context = pyblish.util.publish()
With context at hand, we can now format the results using the results dictionary stored within.
results ="results")
header = "{:<10}{:<40} -> {}".format("Success", "Plug-in", "Instance")
result = "{success:<10}{plugin.__name__:<40} -> {instance}"
results = "\n".join(result.format(**r) for r in results)
report = """
line="-" * 70))
The actual output is this.
Success Plug-in -> Instance
1 CollectCurrentWorkingDirectory -> None
1 CollectCaptainAmerica -> None
1 CollectCurrentUser -> None
0 ValidateCaptainAmerica -> Captain America
The plug-ins CollectCurrentWorkingDirectory and CollectCurrentUser are included by default with Pyblish and adds the following data to the context.
cwd: The current working directory at the time of publish
user: The currently logged on user
