Software Hardware Architecture — Feasible Speculations
Working Wandbox-ed modern C++ code, is HERE.
C++ Polymorphism with no inheritance is by no means, somewhat advanced concept. But, this is just because it is (in C++) based on different concepts v.s. some other good and popular languages where it is in the foundations of the language design.
For example in GO LANG polymorphism is definitely not tied to inheritance. And this is one very much popular and good programing language, indeed. Continue reading “C++ Polymorphism with no inheritance”
Perhaps a bit more usable std::any . Let me know, and we might make it even more usable. If already it is not, that is. Continue reading “C++ Usable std::any”
I think I have architected, designed and implemented, what might be (a bit) better Factory Pattern. Of course, I am pretty sure someone else has discovered the same variation.
Of all the patterns, very often, I was particularly bothered with “classical” aka legacy, Factory. Yes, once implemented, you can relatively easily make it create new “things”, but on the design and usability level, to me, it does not look very flexible and expandable.
On the C++ level it requires code repetition and use of smart pointers. In essence these two combined, somehow do not look to me like modern C++ at all. Continue reading “C++ The Modern Factory”
Just how many times you have admitted to yourself it was rather foolish to think of globals in C++ as “a simple thing” 🙂 After all: What could possibly go wrong? If you know what I am talking about please proceed.
As it turns out many things can and will go wrong, with what you think of as C++ global variables and functions. I am sure every now and then, you are wondering why is this singleton not a singleton, why is this function called more than once, and how it is, that nobody seems to care?
After many years of various coding idioms, that handle static linkage and global variables, and the famous “Singleton Pattern” implementations, may I be so bold to remind you: you do not have to dance around these issues any more.
In case you like to experiment and learn modern C++, you will be needing some R&D little nuggets of your own.
For example. C++ is notorious for its powerful meta programming capabilities. Thus it is very likely, in your C++ quest, you need to see the name of some type that is giving you headache.
