is there a way to pretty print a module? like:

module Main where import Language.Haskell.TH main = do print $ pprint Main

haskell-src should be able to do that.

I think haskell-src requires you to read the module at run time. I want to embed the contents of the module in my program. Basically a program that can print itself.

This is rather like the idea of a quine; a program the prints itself out without referring directly to its own source code. The usual Haskell quine is: putStrLn$(\s->s++show s)"putStrLn$(\\s->s++show s)" If merely returning the source code is enough then you can do: (\s->s++show s)"(\\s->s++show s)" It could be more elegant if \ weren't both lambda and string escape. -- src/
