random-strings-0.1.0.0

A simple way to generate random strings for testing and benchmarking.

A purely random character string is not always the best test case for testing and benchmarking. These modules help generate random strings with preferences for character sets and character properties.

Example:

module Main ( main ) where

import Test.RandomStrings

iso_alpha = onlyAlpha randomChar8
ascii_alphanum = onlyAlphaNum randomASCII

-- print a list of 30 random alphanumeric strings between 5 and 25
-- chars long.

main = do
    words <- randomStringsLen (randomString ascii_alphanum) (5,25) 30
    mapM_ putStrLn words

Build the example with cabal build readme-example.

Functions allow tuning strings for character class and toying with the distribution of alphabetic and upper/lower-case characters.
