Enabled by default	Safe	Supports autocorrection	VersionAdded	VersionChanged
Disabled	No	Yes (Unsafe)	0.81	-

This cop checks whether trailing commas in block arguments are required. Blocks with only one argument and a trailing comma require that comma to be present. Blocks with more than one argument never require a trailing comma.

Examples

# bad
add { |foo, bar,| foo + bar }

# good
add { |foo, bar| foo + bar }

# good
add { |foo,| foo }

# good
add { foo }

# bad
add do |foo, bar,|
  foo + bar
end

# good
add do |foo, bar|
  foo + bar
end

# good
add do |foo,|
  foo
end

# good
add do
  foo + bar
end
