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.
