[Haskell-cafe] hflags

6 Feb 2015

      with ghc 7.8.4 and hflags 0.4 the following program:

{-# LANGUAGE TemplateHaskell #-}

module Main where

import HFlags

defineFlag "f" True "A flag."
--defineFlag "g" True "Another  flag."

main = do
  _ <- $initHFlags "flags demo"
  print Main.flags_f

gives me a runtime error about the flag f not being found, unless I add the
declaration of a second flag. It seems like the last flag definition is not
seen.

Any idea/suggestion?

Thanks,

  Maurizio
