Hi everyone,
Can anyone advise a symbolic algebra library written in dlang?

I've been looking for something akin to https://www.ginac.de/ as well.

I wonder how difficult it would be to create bindings to ginac. Supposedly D is good at interoperating with C++ now. Some time ago I did use ginac from D, but a little differently. There is little advantage to using D for the symbolic algebra part. I wrote up a C++ library with functions to do the calculations, created a .so, and called it from D. Then I decided I didn't want to mess with C++ at all, so I wrote a D function that would take the symbolic algebra part as a string, compile a C++ library, and I used that from D. I suppose that is a bit of a hack, but it only took a few minutes to add that functionality to D. Writing a quality symbolic algebra library would take many years and wouldn't provide much benefit.
