DSAnnotation is a modular Clang-based tooling pipeline that scans C++ translation units for Declarative Services annotations and emits a merged OSGi-style manifests compatible for CppMicroServices Declarative Services.

##Requirements Being a clang tool it obviously depends on the LLVM clang. However, to achieve the AST parsing, it requires a few more clang, libclang-dev and LLVM libraries which might not come in pre-released LLVM zips.

In unix the following packages should give you everything:

apt-get install clang llvm libclang-dev

However, on windows you might need to build LLVM from source, to get all the dependencies.

cmake -S . -B build 
cmake --build build --config Release

The top-level CMakeLists.txt exposes:

• dsannotation_core, dsannotation_support, dsannotation_parsing, dsannotation_serialization – structured static libraries
• dsannotation – CLI executable
• dsannotation_tests – GoogleTest suite (see below)

build\dsannotation.exe --help
build\dsannotation.exe -p path\to\compilation_database -i path\to\existing\manifest.json -o out\dir source.cpp

Output is written to ParserConfig::outputDirectory / ParserConfig::outputFileName (default manifest.json). Existing manifests are merged so custom bundle metadata is preserved.

cmake --build build --target dsannotation_tests
ctest --test-dir build -C Release

Additional unit tests are being added under tests/ and linked against the modular libraries.
