# Documentation

quote :: String -> String #

`quote` adds double quotes around the string, replaces newline characters with `n`, and escapes double quotes and backslashes within the string. This is different from the behaviour of `show`:

    > putStrLn $ show "\x2200"
    "\8704"
    > putStrLn $ quote "\x2200"
    "∀"

(The code examples above have been tested using version 4.2.0.0 of the base library.)

showIndex :: (Show i, Integral i) => i -> String #

Shows a non-negative integer using the characters ₀-₉ instead of 0-9.

addFinalNewLine :: String -> String #

Adds a final newline if there is not already one.

indent :: Integral i => i -> String -> String #

Indents every line the given number of steps.

newtype Str #
