C++ web frameworks: how to compare? For the database layer, I am currently weighing up ODB, Oat++, SOCI, cppdb, and sqlpp11 if sqlpp adds support for `CREATE TABLE`. Also drogon seem to have its own ORM layer, but with only PostgreSQL and MySQL support I'm a little worried from a testing and server-less perspective (really would be nice to see support for an embedded database like SQLite). For the REST API layer I haven't started investigating, although I do remember actix being dethroned and the drogon C++ framework taking its place. --- I am planning to use LLVM (clang, libclang, libtooling) to synchronise bidirectionally OpenAPI with C++ code. I've done the same in Python, and WiP for Rust, Swift, Java, Kotlin, and TypeScript. With my compiler driven approach, I expect people to be able to rapidly produce REST API + db backends with full test and doc coverage, and be able to immediately translate the interfaces across language boundaries (e.g., to frontends, or to rewrite a slow-performing Python backend in C++ or Rust). Currently focussing on the non-Turing-complete as aspect of this, translating just the interfaces, tests, docs, defaults, and types. --- I am writing tools to allow engineers to develop faster, and with higher quality. Will only target one ORM and one REST API layer for C++, at least in the short-term. So my question is, and I understand that posting here will provide a heavily biased answer, how do I decide between the various C++ frameworks? Thanks https://redd.it/maicqm @r_cpp

Italian C++ Conference 2021 - Call for Sessions Since 2016, the Italian C++ Conference is the biggest and most successful event organized by the Italian C++ Community where professionals, companies and students meet to share experience about C++ development and practices. The next conference is planned for June 19, online (Remo) and will be free to attend (as usual). The call for sessions is open here: https://www.italiancpp.org/eventi/cfs/ ​ We look forward to receiving your proposals! ​ PS Can you please help us spread the word? :) https://redd.it/mb9zos @r_cpp

Library in C ++ So I'm currently looking to create a program in C ++ of a library, that does the basics, add books remove books also an array that saves the books created and finally a menu with options for all the above. Just looking to get guidance as I try to make it. Thx.. https://redd.it/mbb5g4 @r_cpp

Call python executable code in c++ I am doing my research in networking and i want to implement Multivariate linear regression on my own data set(numeric).... i used python for multivariate linear regression using sklearn library and now i want to embed/call that python implementation from my c++ code... AS if i say that c++ is my application and python code is a service which provides services to my c++ code.... and i need python code output in c++ code so i want to call python executable in c++.... can i do that.... i search a lot as boost one is but i am not understanding how can i do... i used jupyter notebook for python and eclipse for c++.... is i can call python code...because i have using own sklearn library and if i implement multivariate linear regression in c++ then how can i apply because i now python but no idea how can i deal with larger data set using c++ https://redd.it/mak9xy @r_cpp

Is there a page that lists the exact differences between the coding standards of Google, Gnu and Coreguidelines? I'm just trying to find an overview. Thanks in advance.

Guideline for passing smart pointers sharedptr and uniqueptr in functions https://levelup.gitconnected.com/passing-smart-pointers-in-c-479775632443 Hi All, I have compiled few guideline diagrams article on how to pass shared_ptr and unique_ptr in function arguments for optimal performance and what to pass at the time of return. After reading Herb's blog, C++ guidelines, and a few other references I have put together this and few guideline matrices which are in this article. This article covers the following - 1. Always ask yourself “Do I really need to pass a smart pointer” 2. std::unique_ptr usage 3. std::shared_ptr usage 4. How to pass correctly pass raw pointer/reference. 5. For Returning smart pointers, what is the norm? I searched but never found a good graphical representation of these guidelines, hence I thought I'd give that a try :) Please help me in improving anything which is incorrect or missing in this. https://redd.it/ma1l5y @r_cpp
