Re: [Quantlib-users] How to expose QuantLibAddin to Python?

That's an interesting exercise to attempt.  An XLL is a DLL so I guess 
there is nothing to prevent you from loading it as such into Python.  
But the XLL's entry points are designed to be called from Excel so it 
would be a hassle at best to use from Python.

The idea behind gensrc is that you could autogenerate source code for 
the QuantLibAddin interface for any platform, Excel is just one 
example.  There is a build for C++ but it only supports a subset of the 
functionality that QuantLibXL supports.  So the C++ build is more of a 
proof of concept.  It works on Windows and Linux and is documented here:


https://www.quantlib.org/quantlibaddin/build_cpp.html


Once upon a time, we implemented a gensrc module to export the 
QuantLibAddin interface to C, and that facilitated deployment to 
platforms such as Python that talk C.  However that build has not been 
maintained for a long time and it would not be a trivial task to 
resurrect it.
