# Documentation

quote :: String -> String Source #

`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.)

haskellStringLiteral :: String -> String Source #

Turns the string into a Haskell string literal, avoiding escape codes.

delimiter :: String -> String Source #

Adds hyphens around the given string

    >>> putStrLn $ delimiter "Title"
    ———— Title —————————————————————————————————————————————————

addFinalNewLine :: String -> String Source #

Adds a final newline if there is not already one.

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

Indents every line the given number of steps.

showThousandSep :: Show a => a -> String Source #

Show a number using comma to separate powers of 1,000.

ltrim :: String -> String Source #

Remove leading whitespace.

rtrim :: String -> String Source #

Remove trailing whitespace.

trim :: String -> String Source #

Remove leading and trailing whitesapce.
