Overview

Beloved squiggly heredocs did not exist in Ruby 2.1, which we still want to support, so let’s give kudos with a method ‘sq`.

Instance Method Details

#sq(str) ⇒ Object

Outdents each line on a multiline string by the number of leading whitespace characters on the first line.

This method exists so we can unindet heredoc strings the same way that Ruby 2.2’s squiggly heredocs work, but still support Ruby 2.1 for the time being.

For example:

str = sq(<<-str)

This multiline string will be outdented by two characters,
  so the extra indentation on this line will be kept,
while this line sits on the same level as the first line.
