I'm working on a literate haskell document (actually TeX, but the example below is just test) and I'm using ByteStrings in the code. I know I can do:
ghci -XOverloadedStrings file.lhs
or, after ghci is running I can do:
Main> :set -XOverloadedStrings
but I'd like to embed a directive in the file so that when loaded in GHCi, I will automatically get OverloadedStrings. This is mainly so that it JustWorks(tm) when I pass the file on to someone else.
Is there a way to do this?
There is a short example file below. I'm using ghc-7.0.4 from Debian testing.
it does not seem to be related to literate haskell, if I copy the code from your file into a .hs without the "> ", ghci still does not activate the OverloadedStrings extension when loading the file. I’d consider this a bug until the developers explain why this should or cannot be different, and suggest you file it as such.
