Raw string

We have a text string with a non-standard characters. To avoid possible problems with formatting and, in addition, to avoid frequent usage of backslash we will use a raw string. Each symbol in the raw string is a symbol itself.

Solution

We have to install raw-strings-qq. Now:

{-# LANGUAGE QuasiQuotes #-}

module Main where

import Text.RawString.QQ

helpInfo :: String
helpInfo = [r|

This is raw string, "strange
  -- Very strange
  {-
  '"Yes, very strange\ string"
  -}

But in some cases 
                   it's 
            very convenient...
  |]

main :: IO ()
main = putStr helpInfo

And this is our strange result:

This is raw string, "strange
  -- Very strange
  {-
  '"Yes, very strange\ string"
  -}

But in some cases
                   it's
            very convenient...

Done.
