class Ameba::Rule::Lint::RedundantWithObject

Overview

A rule that disallows redundant each_with_object calls.

For example, this is considered invalid:

collection.each_with_object(0) do |e|
  # ...
end

collection.each_with_object(0) do |e, _|
  # ...
end

and it should be written as follows:

collection.each do |e|
  # ...
end

YAML configuration example:

Lint/RedundantWithObject:
  Enabled: true
