I would like to tell Cabal which modules are required and which are
supported, or recommended, but not needed. I could split Haskore into
several packages, but then again, installation of Haskore and its
sub-packages becomes uncomfortable and the Haddock documentation has no
longer a common table of contents. I tried to write custom Setup code for
finding out which parts of Haskore cannot be installed due to unsatisfied
dependencies, but this is more complicated than I hoped.
such feature was already requested by Robert Dockins
in libraries list at June 8. He wrote:
"This brings up a feature I have sometimes wanted from Cabal. I'd
like to be able to say the following: "Cabal, find and use package X
if it exists. Furthermore, when CPPing source code, set a #define
HAS_PACKAGE_X so I can do conditional compilation based on the (non-)
avaliablility of package X". Is this possible? Difficult? It seems
like a nice way to handle a number of problems, including platform-
dependencies (as here) and optional features with external
dependencies."
you can add your voice to the peoples requesting this feature (i need
it, too)
