# This Rubocop will check for specifying the `prefix` keyword argument on `StatsD` metric
# methods and `statsd_*` metaprogramming methods. To run this cop on your codebase:
#
# rubocop --require `bundle show statsd-instrument`/lib/statsd/instrument/rubocop.rb \
# --only StatsD/MetricPrefixArgument
#
# This cop will not autocorrect offenses.
class MetricPrefixArgument < Cop
include RuboCop::Cop::StatsD
MSG = <<~MSG
Do not use StatsD.metric(..., prefix: "foo"). The prefix argument is deprecated.
You can simply include the prefix in the metric name instead.
If you want to override the global prefix, you can set `no_prefix: true`.
