Toy.Generic
Description
Rationale
I find rather too much boilerplate in little Haskell command line toys I write.
This module is an attempt to abstract that common code, in the hope that I'll both be more efficient and write less hacky tools.
Often particular modules will be more helpful when writing code which e.g. handles Images with Juicy Pixel.

processGeneric :: (FilePath -> FilePath -> IO ()) -> (String -> String) -> String -> FilePath -> IO () Source
processGeneric makes it easier to apply functions
which take input and output filenames to a list of
input names, by programmatically constructing the
output name. Typically we munge the basename, then
e.g. change the suffix:
processGeneric mungePNG (++ "-m") (f -> replaceExtension f "png")
processArgs :: (FilePath -> IO ()) -> IO () Source
processArgs just calls a function with every command
line argument.
main = processArgs putStrLn
