ANN: MatchPyCpp port to C++

[Upabjojr]

ANNOUNCEMENT:

I have ported parts of MatchPy into C++: https://github.com/symengine/symengine/pull/1497

• symengine library has been used for expression trees,
• only the parts of MatchPy needed by the generated code have been ported into C++,
• the C++ code generator is written in Python and still relies on MatchPy library.

Thank you very much for letting us know! Are you planning to do any experiments to compare the performance of the generated C++ code to the generated Python code? I would be curious about that.

Are you planning to do any experiments to compare the performance of the generated C++ code to the generated Python code? I would be curious about that.

At the moment I'm quite busy, I hope to get a GSoC student to port RUBI into C++.

Currently I'm not sure about the speed-up of C++, as many of the generators are solved (i.e. instead of yield value they return the array of values, performing all combinations). There are some solutions for this problem, but I would like to first wait and see whether coroutines will be added to the C++20 standard. Alternatively there are some tricks to force the usage of generators into C++.

If this problem is solved, I expect C++ to be a lot faster.

@Upabjojr if the issue is still persisting and you would want a contributor to work on it I am available please let me know the pre-requisite for the same and i'd be happy to contribute.

Are you willing to port the code to C++20?

[MANIKTANEJA3]

Sure I’d need guidance on the same and will have to check for the methods but am in for it

I’ve opened a thread on the forum should I propose another application or should I start working on it? Please guide me as the deadline is approaching . Thank you

Also @Upabjojr I've read through your work and the implementations before starting off to work on the port. I've also read through the following repository https://github.com/luncliff/coroutine/tree/master/interface/coroutine . Correct me if I'm wrong here ; The steps to port the code is to pick any function create a header file for the same and then the implementation? because i saw both (.h) and (.cpp) files in SymEngine's repository.
