Open source implementations of Apple SDK macros.
Note: This package is currently WIP. See xtool#101
This package is used by xtool: OpenAppleMacrosServer is installed into the Darwin SDK that we build.
Specifically, OpenAppleMacrosServer is a drop-in replacement for Xcode.app/Contents/Developer/Platforms/*.platform/Developer/usr/bin/swift-plugin-server.
The only other caveat is that we have to replace the lib<FOO>Macros.dylib files (in *.platform/Developer/usr/lib/swift/host/plugins/) with empty lib<FOO>Macros.so files, so that swiftc registers them as macro modules. The files stay blank because we don't actually split the macros up into shared libraries. Instead we merge all of the macros into the OpenAppleMacrosServer executable, and statically link it, for maximum portability.
The easiest way to build the server yourself is by running make docker.
You can test out the server by replacing darwin.artifactbundle/OpenAppleMacrosServer with the built output/OpenAppleMacrosServer-$(arch).
