In a project I have currently some program text embedded as String in the
source code. I like to move that to an extra file, such that I can test
the program without running the Haskell code and such that non-Haskell
programmers can adapt the text. However, I hesitate to use the Data-Files
feature of Cabal since this would mean that I can test the Haskell code
only after installation of the whole Cabal package including the text
file.
Is there a way to use 'cabal repl' with the local version of the text
file? This would mean there must be a different variant
autogen/Paths_mod.hs, maybe the same file name but in a different
directory that is only passed to GHCi by 'cabal repl'. Manageable but
certainly surprising? Maybe only available by a new option like 'cabal
repl --local-dirs'.
More difficult: Can even 'cabal build' incl. dist/build/prog/prog and
'cabal run' use local data files per request? Certainly not, since
dist/build/prog/prog shall just be installed by 'cabal install'.
Alternatively, is there a way to tell GHC to include a file in the
executable and provide access to its content? Would there be support in
Cabal for this feature?
