Helper method for dealing with heredoc strings.

require "jsduck/doc_formatter"

class String

  # Removes beginning-whitespace from each line of a string.

  # But only as many whitespace as the first line has.

  #

  # Ment to be used with heredoc strings like so:

  #

  # text = <<-EOS.heredoc

  #   This line has no indentation

  #     This line has 2 spaces of indentation

  #   This line is also not indented

  # EOS

  #

  def unindent

    lines = []

    each_line {|ln| lines << ln }

    first_line_ws = lines[0].match(/^\s+/)[0]

    re = Regexp.new('^\s{0,' + first_line_ws.length.to_s + '}')

    lines.collect {|line| line.sub(re, "") }.join
