Don't skip lines with no data after "=", as there are many presets with empty code lines. skipping it would create a gap in the line numbers, aborting the loop in GetCode() early.
Requires a general rewrite of the Milkdrop preset code. Previous implementation was tightly integrated into the code parser, so reusing this code wasn't possible. Additional refactoring was done, finished converting custom wave/shape implementations to use the new expression parser code.
Other changes:
- Renamed Parser to OldParser to make it clear this is going away.
- Removed all the useless "unit tests" which did not actually test anything.
- Added a new GTest-based test executable that can be run with CMake's CTest.
- Added unit tests for the new fileParser class, including test files.
Removed dependency on projectMtarget alltogether, as the playlist tests don't need the core library at all, only a few API functions which are mocked. Also made sure the mocked functions are declared as dllexport on Windows to match the dllimport declspec in the playlist library.
Target name is now just libprojectM::projectM for the main library instead of libprojectM::static or libprojectM::shared.
Now using CMake's default mechanism to select the resulting library type via the BUILD_SHARED_LIBS variable. Main use case will be working with the shared library, which is the default.
Playlist library now also builds as a shared library, including proper symbol exports.
Additionally, deleted the leftover TestRunner class and a few old and rather useless test cases.
Also added LLVM find_package call and as a link dependency if the build is configured for using (experimental) LLVM code.
Reorganized tests to link either one of the object libraries for unit testing.
Path scanning is using C++17's std::filesystem if available, but uses boost::filesystem as fallback. Using boost can be forced using the ENABLE_BOOST_FILESYSTEM CMake option.
