Defined in:

Overview

Checks that the equals signs in parameter default assignments have or don’t have surrounding space depending on configuration.

Examples:

EnforcedStyle: space (default)

# bad
def some_method(arg1=:default, arg2=nil, arg3=[])
  # do something...
end

# good
def some_method(arg1 = :default, arg2 = nil, arg3 = [])
  # do something...
end

EnforcedStyle: no_space

# bad
def some_method(arg1 = :default, arg2 = nil, arg3 = [])
  # do something...
end

# good
def some_method(arg1=:default, arg2=nil, arg3=[])
  # do something...
end
