Ruby: Is there a right way to indent a case statement? [closed]

Question

A number of blogs and tutorial have different indentations when they implement a case statement. Each have different indentation in reference to the 'when' lines. Is there a best practice for indenting when using a case loop?

Answer 1

The consensus is to indent when as the same level as case.

case sym
when :foo then ...
when :bar then ...
else ...
end

I think this is well established, and have not seen any authentic source that claims otherwise.

Answer 2

This is the way I've seen it used. The 'what happens in the event of the 'when' should be on the next line and indented.

case something
when 'a'
  what happens when 'a'
when 'b'
  what happens when 'b'
when 'c'
  what happens when 'c'
end
