There is a GHC ticket about implementing a DEPENDS pragma for doing
this [0]. There are patches attached, but it looks like it isn't
finished yet.

Hi.
we are using template Haskell to splice in some code that is produced by reading and transforming the contents of another file.
now, if this "other file" is touched (by editing), but not the main file, then ghc (and cabal) do not realize that the main file does need to be recompiled.
is there a way to tell them about the dependency?
(example main file: https://github.com/apunktbau/co4/blob/master/CO4/Test/Queens.hs)
