class Ameba::Rule::Lint::ShadowingOuterLocalVar

Overview

A rule that disallows the usage of the same name as outer local variables for block or proc arguments.

For example, this is considered incorrect:

def some_method
  foo = 1

  3.times do |foo| # shadowing outer `foo`
  end
end

and should be written as:

def some_method
  foo = 1

  3.times do |bar|
  end
end

YAML configuration example:

Lint/ShadowingOuterLocalVar:
  Enabled: true
