Style/ExplicitBlockArgument

Safe autocorrect: Yes
✅ The autocorrect a cop does is safe (equivalent) by design.

Description

Overview

Enforces the use of explicit block argument to avoid writing
block literal that just passes its arguments to another block.

NOTE: This cop only registers an offense if the block args match the
yield args exactly.

Examples

# bad
def with_tmp_dir
  Dir.mktmpdir do |tmp_dir|
    Dir.chdir(tmp_dir) { |dir| yield dir } # block just passes arguments
  end
end

# bad
def nine_times
  9.times { yield }
end

# good
def with_tmp_dir(&block)
  Dir.mktmpdir do |tmp_dir|
    Dir.chdir(tmp_dir, &block)
  end
end

with_tmp_dir do |dir|
  puts "dir is accessible as a parameter and pwd is set: #{dir}"
end

# good
def nine_times(&block)
  9.times(&block)
end
