class Ameba::Rule::Style::RedundantParentheses

Overview

A rule that disallows redundant parentheses around control expressions.

For example, this is considered invalid:

if (foo == 42)
  do_something
end

And should be replaced by the following:

if foo == 42
  do_something
end

YAML configuration example:

Style/RedundantParentheses:
  Enabled: true
  ExcludeTernary: false
  ExcludeAssignments: false
