AA+ is a C++ implementation for the algorithms as presented in the book "Astronomical Algorithms" by Jean Meeus. The class framework is done by PJ Naughter. It also has implementations in other languages, like JavaScript (aa-js), C# (AASharp) and Swift (SwiftAA). However, always keeping updated with AA+ is difficult.

Thanks to Microsoft's C++/CLI technology and Naughter's excellent coding style. These enable us to compile C++ code into a library that can be used by the dotnet ecosystem with minimal changes.

This project translates native C++ code into C++/CLI based on some simple regexs. Therefore, if the AA+ library is updated in the future, everyone can compile the latest AA+ dotnet library immediately with minimal modification/translation cost.

Currently, the AAPlusSharp corresponds to version 2.52 of AA+.

1. Download aaplus.zip from http://www.naughter.com/aa.html.
2. Extract aaplus.zip and place all files in the input folder.
3. Run AAPCpp2Cli with proper input/output path. Typically ./aaplus and ./AAPlusSharp.
4. Build AAPlusSharp.
