Ruby Heredocs | Alchemists

Ruby heredocs — or here documents — are a nice way to embed multiple lines of text as a separate document in your source code while preserving line breaks, indentation, and other forms of whitespace. This frees you up from having to concatenate multiple lines of strings which can get cumbersome.Heredocs originate from UNIX as generally found in shell scripting. Heredocs are not specific to the Ruby language, though. Other languages incorporate some form of this syntax as well.
