C++17 in details: Templates

C++17 features, templates

For C++17 everyone wanted to have concepts, and as you know, we didn't get them. But does it mean C++17 doesn’t improve templates/template meta-programming? Far from that! In my opinion, we get excellent features.

Read more for details.

Modern C++ Programming Cookbook Review

Modern C++ Programming

Since May 2017 we got one more book about Modern C++! A Few weeks ago I got a copy from Packt Publishing, and today I’d like to write a few words about the book. In short: it’s a very good book! :)

But let’s see what’s inside…

Important: I have three ebooks for you, read more at the end of the post!

C++17 in details: language clarifications

C++17 features, clarifications

The second part of my series about C++17 details. Today I’d like to focus on features that clarify some tricky parts of the language. For example copy elision and expression evaluation order.

C++17 in details: fixes and deprecation

C++17 features

The new C++ Standard - C++17 - is near the end to be accepted and published. There’s already a working draft, and not that long ago it went to the final ISO balloting. It’s a good occasion to learn and understand what are the new features.

Let’s start slowly, and today we’ll look at language/library fixes and removed elements.

Enhancing Visual Studio with Visual Assist

Visual Studio andVisual Assist

How does your typical coding session in Visual Studio look like?
What’s the first thing you do when you’re about to start coding?

Yes… let’s check Gmail, Youtube, Reddit, etc… :)

OK, please be more professional!

So, let’s assume my Visual Studio (2013, 2015 or 2017) is already started. What to do next?

Please stop with performance optimizations!

Stop with performance optimization

As you might notice from reading this blog, I love doing performance optimizations. Let’s take some algorithm or some part of the app, understand it and then improve, so it works 5x… or 100x faster! Doesn’t that sound awesome?

Curious case of branch performance

Branching, performance

When doing my last performance tests for bool packing, I got strange results sometimes. It appeared that one constant generated different results than the other. Why was that? Let’s have a quick look at branching performance.

Packing bools, Parallel and More

Packing bools, performance tests, parallel

Let’s continue with the topic of packing boolean arrays into bits. Last time I’ve shown a basic - single threaded version of this ‘super’ advanced algorithm. By using more independent variables, we could speed things up and go even faster than no packing version! We’ve also used std::vector and std::bitset. Today I’d like to look at making the task parallel.

Packing Bools, Performance tests

Packing booleans, bits

Imagine you have an array of booleans (or an array of ‘conditions’), and you want to pack it - so you use only one bit per boolean. How to do it? Let’s do some experiments!

final_act - follow-up

final_act follow-up

Last time I wrote about final_act utility, and it seems I’ve opened a bit bigger box that I’ve previously assumed. Let’s continue with the topic and try to understand some of the problems that were mentioned in the comments.

Beautiful code: final_act from GSL

Code function

Sometimes there’s a need to invoke a special action at the end of the scope: it could be a resource releasing code, flag set, code guard, begin/end function calls, etc. Recently, I’ve found a beautiful utility that helps in that cases.
Let’s meet gsl::final_act/finally.

C++18, Why not?

C++18 experiments

As you’ve might already notice I’ve made a little joke on Saturday, which was the April Fools’ Day. I got the courage to announce C++18 next year! :)
While it was a bit funny, I didn’t expect much traffic (as it was Saturday). Still, my stats shows that a lot of people clicked and viewed the post. Thanks!

Today I’d like to continue the topic: why not and have C++18?

C++18 Next Year!

C++18 Next Year

I have a great news! During the last meeting in Kona, the committee not only made final notes on the C++17 standard! There’s also a groundbreaking news that behind the curtains they planned C++18!

Windows File Tests

Transform a file on Windows

You want to transform one file into another, input into output. What API will you choose on Windows? WinApi? C++ Streams or good old stdio?

Last year in September I looked at four ways of processing a file on Windows. Also, I did some performance tests.
The whole project description was recently published in Visual Studio Magazine.
