I was attempting to set a control comment to ignore a particular lint check the other day and was having a difficult time figuring out what exactly the check name should be in the
# lint:ignore:<check_name>
comment. I ended up having to dig through the source code for the check in question to find the correct check name string to add to the comment, and thought it would be nice if there was an easier way to list these.They're sort of listed on the Puppet Lint - Checks page, but one has to infer the name of the check by looking at the pattern of the cli options strings, i.e. the actual name of the check is
--no-CHECK_NAME-check
.This provides a simple flag to list out the checks with some basic documentation at the cli. Also includes an update to the README mentioning the feature, and an rspec test to make sure all checks are listed. All tests passing.
