ConfigurableMax

Defined in:

lib/rubocop/cop/metrics/block_nesting.rb

Overview

This cop checks for excessive nesting of conditional and looping constructs.

You can configure if blocks are considered using the ‘CountBlocks` option. When set to `false` (the default) blocks are not counted towards the nesting level. Set to `true` to count blocks as well.

The maximum level of nesting allowed is configurable.
