Instance Method Details

#strip_heredoc ⇒ Object

Strips indentation in heredocs.

For example in

if options[:usage] puts <<-USAGE.strip_heredoc This command does such and such.

  Supported options are:
    -h         This message
    ...
USAGE

end

the user would see the usage message aligned against the left margin.

Technically, it looks for the least indented line in the whole string, and removes that amount of leading whitespace.
