This is a fortune-mod clone. In addition to the features generally expected of a
fortune program, this can be used as a Haskell library (
import Data.Fortune) and also supports UTF-8 fortune files, configurable search paths, automatic merging of fortune databases with the same name (so you can have a local fortunes folder that just adds to existing fortune databases), filtering fortunes by line lengths, and a "print fortune matching regex" mode (instead of just "print all fortunes matching regex" mode).
Most of the command-line flags from
fortune work with
misfortune as well. To just print a fortune, run:
To index a new fortune file (or update the index on an existing one), run:
To use the fortune API in your Haskell programs:
import Data.Fortune import qualified Data.Text as T main = do f <- openFortuneFile "pangrams" '%' True appendFortune f (T.pack "The quick brown fox jumps over the lazy dog.") appendFortune f (T.pack "Quick blowing zephyrs vex daft Jim.") closeFortuneFile f putStrLn =<< randomFortune ["pangrams"]
This example will create or append to a file "pangrams" in the working directory, and create or update the corresponding index file "pangrams.dat". It then closes that file and requests a random fortune from all databases named "pangrams" in the search path - so it will either print one of the two just written or one found in another "pangrams" file. Every eligible fortune is equally likely.
