Hi, I'm experimenting with a preprocessor to automatically generate test drivers[1]. The result depends on the existence of other files on the disk. When files are added or removed, the test driver has to be regenerated. Ideally ghc would just always recompile that single file (akin to make's .PHONY), and it should work with ghci's :reload and with cabal. I tried to touch the file within the preprocessor, but this does not work. It seems, that GHC checks the modification time only after preprocessing. Any ideas how to tackle this?
