Text.Zalgo

Provides facilities for generating a wide range of glitched/creepy text through horrifying abuse of diacritics.

Pure interface

zalgo :: RandomGen g => String -> g -> (g, String)

Zalgo the given text using the default zalgo settings and the given generator.

zalgoWith :: RandomGen g => ZalgoSettings -> String -> g -> (g, String)

Zalgo the given text, using the given algorithm settings and generator.

gradualZalgo :: Double -> String -> StdGen -> (StdGen, String)

Gradually zalgo the given string, starting from the given threshold and linearly scaling towards the default zalgo settings.

unZalgoWith :: ZalgoSettings -> String -> String

Exorcise Zalgo from the given string using the given settings.

redact :: RandomGen g => [String] -> String -> g -> (g, String)

Blot out any occurrence of the given needles in the given string using extreme zalgo.

Effectful interface

zalgoIO :: String -> IO String

Zalgo the given text using the standard settings and a fresh generator.

zalgoIOWith :: ZalgoSettings -> String -> IO String

Zalgo the given text with the given settings, using a fresh standard generator.

gradualZalgoIO :: Double -> String -> IO String

Zalgo the given text using a fresh random generator, starting after the given fraction of the input string, from there on scaling the zalgo factor linearly towards the default settings.

gradualZalgoIOWith :: ZalgoSettings -> Double -> String -> IO String

Zalgo the given text using a fresh random generator, starting after the given fraction of the input string, from there on scaling the zalgo factor linearly towards the given settings.

redactIO :: [String] -> String -> IO String

Like redact, but with a fresh random generator.

Printing functions

printZalgo :: String -> IO ()

Print zalgo'd text using the default settings and a fresh default generator.

printZalgoWith :: ZalgoSettings -> String -> IO ()

Print zalgo'd text using the given settings and a fresh random generator.

printGradualZalgo :: Double -> String -> IO ()

Gradually zalgo and print the given text starting at the given threshold. Uses default settings and a fresh system default generator.

printRedacted :: [String] -> String -> IO ()

redact and print the given needles and haystack.

Configuration

data ZalgoSettings

maxHeightAt :: ZalgoSettings -> Int -> Int

Maximum number of diacritics above or below a character at the given position of the input string.

Default: const 10

varianceAt :: ZalgoSettings -> Int -> Double

Maximum random variance in height, as a fraction of maxHeight, at the given position of the input string.

Default: const 1

overlayProbabilityAt :: ZalgoSettings -> Int -> Double

Probability of generating an overlay character at the given position of the input string.

Default: const 0.4

numOverlayCharsAt :: ZalgoSettings -> Int -> Int

Number of characters to use for overlay at the given position of the input string. The number of overlays for any character will always be this number or zero.

Default: const 1

overlayCharset :: ZalgoSettings -> Array Int Char

Charset from which to pick overlay characters.

Default: defaultOverlayCharset

defaultZalgoSettings :: ZalgoSettings

The default zalgo settings. Creepy yet readable.

unreadableZalgoSettings :: ZalgoSettings

Settings to make text completely unreadable.
