http://www.haskell.org/ghc/docs/latest/html/users_guide/separate-compilation... Recently, I stumbled on -v2 in combination with --make or -M, which produces nice module-based output instead of the file-based makefile dependencies of -M, but have run into a couple of : 1. --make can't be used with -fno-code, and -M always generates a file, so is this the best one can do: ghc -M -v2 -optdep-f -optdep depend Main.hs ? It would be nice to have the dry-run option (isn't that -fno-code?) work with all commands that produce useful stdout information (including --make -v2). 2. I can't seem to figure out what --include-pkg-deps does? In a way, it seems to be always on, since package imports are always listed in the -v2 output. Claus
