Description
Generate cabal_macros.h - CPP macros for package version testing
When using CPP you get
VERSION_<package> MIN_VERSION_<package>(A,B,C)
for each
package
in
build-depends
, which is true if the version of
package
in use is
>= A.B.C
, using the normal ordering on version
numbers.
TODO Figure out what to do about backpack and internal libraries. It is very suspecious that this stuff works with munged package identifiers

The contents of the
cabal_macros.h
for the given configured package.
generatePackageVersionMacros :: [ PackageId ] -> String Source #
Helper function that generates just the

and
MIN_VERSION_pkg

a configured package).
