Description
As long as I develop a package without Data-Files I can run and test my program locally using cabal run and cabal repl. As soon as I start to use Data-Files, the trouble begins. If I am in ghci/cabal repl I cannot simply hit :reload (or omit even that, since Haskell modules are not affected by Data-Files) anymore in order to adapt to changes in the Data-Files. I have to run cabal install. However, this may fail, since the program is temporarily incorrect.
Is there a way of using the local Data-Files when I do cabal run and cabal repl and using installed Data-Files when running programs from .cabal/bin? A way to achieve this might be Data-Files that are accessed relative to the path of the executable.
