PseudoMacros
Description
The pseudo-macros in this module are meant to be used via Template Haskell (see http://www.haskell.org/ghc/docs/latest/html/users_guide/template-haskell.html for more information).
Example:
{-# LANGUAGE TemplateHaskell #-}
import PseudoMacros
main :: IO ()
main = putStrLn ("Hello from " ++ $__FILE__ ++ ", line " ++ show $__LINE__ ++ "!")That is, enable the TemplateHaskell extension and put a $ before each
pseudo-macro.
