Seems like the answer is "yes"

The answer is yes as long as the compiler version and the versions of all libraries your orignal .hs file used remain the same. As soon as any of these versions change, you need the full original .hs file.

They are used: any library installed with e.g. cabal-install is kept around not in source form but with .hi and .o files (and perhaps some metadata as well.) Best regards, Krzysztof Skrzętnicki On Fri, Mar 22, 2013 at 11:04 PM, MigMit wrote:

Seems like the answer is "yes" — by creating a fake .hs file (with no real content) and touch-in .hi and .o files I tricked ghc so that it didn't attempt to recompile the module, so the information in .hi and .o files is sufficient. But ghc insists on having the .hs file around, and I didn't find a way to turn it off. Is there any? Or there is a specific reason not to allow this? _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
