class RuboCop::Cop::Layout::SpaceBeforeFirstArg

Checks that exactly one space is used between a method name and the first argument for method calls without parentheses.

Alternatively, extra spaces can be added to align the argument with something on a preceding or following line, if the AllowForAlignment config parameter is true.

@example

# bad
something  x
something   y, z
something'hello'

# good
something x
something y, z
something 'hello'
