What's this?

indent!(amount, indent_string = nil, indent_empty_lines = false) public

Same as indent, except it indents the receiver in-place.

Returns the indented string, or nil if there was nothing to indent.

# File activesupport/lib/active_support/core_ext/string/indent.rb, line 7
  def indent!(amount, indent_string = nil, indent_empty_lines = false)
    indent_string = indent_string || self[/^[ \t]/] || " "
    re = indent_empty_lines ? /^/ : /^(?!$)/
    gsub!(re, indent_string * amount)
  end

indent!
