Fluent in C++
-
Glad to see you enjoy the new goodies. In my previous job, elephanting legacy forced us to stick with C++03. X|
for(auto index: my_vector)is cool.for(const auto& index: my_vector)even more so! And, today we do not have to use pointers in containers any more. :cool:... such stuff as dreams are made on
C++98 a la VS6. In 2016.

Please forgive my curiosity. You have been in that place for quite some time (I think), do you ever consider a switch?
... such stuff as dreams are made on
Almost 5 years, 9 months as a (paid) intern, 3 years as apprentice and then finally hired for good. I am considering a switch, for a number of reasosn, mostly for the low pay for the job I do but the working environment has its faults that are grating on my nerves after all this time. Its 4 years and a half that we have to upgrade to VS2008, I started using it but was forced every effing time to reimport all the changes in the VS6 project and fix the effing code because several things present and accepted in VS2008 fail under VS6. I stopped due to frustration.

So, as some of the longer term viewers may know, I used to be a C++ developer; way back in the mists of time. I loved C++ and then the new girl came to town and seduced me with her wiles. No longer would I put up with manual memory management, iterating over for statements when I could use the seductive foreach. Well, I have recently started getting quite heavily back into C++ using the newer additions to the language such as auto and for (auto index : my_vector) as a foreach. The features that are available now are great and C++ really has matured. So much so that I'm using it to write some drone software. I'm a big fan of fluent interfaces so I thought I'd play around and see how they work in C++ to see if I still want to keep with the new C++ and damn it, it's so straightforward.

Indeed, modern C++ ist an elegant language. It has one huge flaw though: It's legacy. I, for example, can write elegant code in modern C++, but several of my coworkers can't. Some even brush me off with "I've learned it like that in the 60s and I won't learn anything new". Some even treat the C++-compiler as a C-compiler and write plain C, bluntly ignoring all the wonders of std::string or array. This makes me think that C++ still isn't ready for prime-time. The standard needs to deprecate all this legacy stuff and throw warnings all over the place if someone refuses to dig into the last 50 years of CS progression. If C++ starts doing that, I'll take it seriously. Until then, I'll stick to C# (unless I'm on a ressource-contrained embedded target).

Welcome back to the codeface! ;) C++ 14 is amazing, and a very different language from the one I had to use until a few years ago. We had the pleasure of meeting Bjarne at the ACCU Conference a few years back when C++ 11 first landed, and his enthusiasm for the future of the language was infectious. I'm a big fan of std::shared_ptr, auto, range based loops and std::thread. All have (and still are) simplifying our code significantly. Then of course there are move semantics and rvalue references, which can dramatically improve performance. But more is coming - C++ 17[^] is nearly done (though sadly without the modules proposal[^], despite it already being implemented in Clang) and C++ 20 is being planned.

It's a vastly different language to the one I knew. As I have the advantage of writing from scratch, I have the advantage of not having to deal with legacy and cruft. It's a liberating experience.

This sounds like me. I was once quite proficient in C++ but then I got into C# and simply haven't updated my C++ at all. Last time I used it was in 2003 I think. The latest versions look so different and have so many new features that I would really have to study hard to catch up.
We're philosophical about power outages here. A.C. come, A.C. go.

All of the input and output operators in old, old C++ offered fluent interfaces. cin >> x >> y; cout << setw(10) << x << setw(12) << y << endl; Ignoring references, you can always just
return this;
at the end of a function which requires code like:
variable->f1(args1)->f2(args2)->f3(args3);

I'm happy enough with what I've got now.

It certainly is. :) Thought of coming along to the ACCU Conference? There's a strong C++ track (and sometimes even a C++ Pub Quiz with free beer...) there.

It depends how serious I get with this drone software. The more I'm playing around with this, the more I love working with drones and I can see me going further with it.

I'll be writing this up and posting video footage so you will be able to take a look at least at some of the code. It's really cool stuff.

You seem to be retaining the C# coding style, single-file and all :)

I'm really not. It was just easier to post a sample like that. My real code is spread out.

C++ and MFC; I did everything I could to avoid that sack of shite: Basic Assembler PC COBOL Pascal C Access dBase Paradox VB Clipper FoxPro Visual FoxPro Delphi C# Windows Forms WPF ...
I spent a lot of time in MFC. Then I discovered ATL and wasee hooked until I moved to .NET.
