Report IV
Visualising results right away is useful, but sometimes you need to go back in time. So how about instead of printing the report, we write it to a file? Better yet, why not develop a plug-in to write the file such that it happens along with every publish?

We copy/paste the formatting from our previous example and chuck it into
format_results, this time returning as opposed to printing.1
def format_results(self, context):

header = "{:<10}{:<40} -> {}".format("Success", "Plug-in", "Instance")

results = list()

for r in context.data["results"]:

# Format summary

results.append(result.format(**r))

# Format log records

for lr in r["records"]:

results.append(record.format("", level=lr.levelname, message=lr.msg))
