Distribution.Simple.Build.Macros
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
Documentation
generate :: PackageDescription -> LocalBuildInfo -> ComponentLocalBuildInfo -> String #
The contents of the cabal_macros.h for the given configured package.
generatePackageVersionMacros :: [PackageId] -> String #
Helper function that generates just the VERSION_pkg and MIN_VERSION_pkg
macros for a list of package ids (usually used with the specific deps of
a configured package).
