C++ Links #3

Welcome to new C++ Links - most important and useful articles, podcasts and videos that happen between 15th and 21st of September.

Today you will find a link to post about “same but different” objects in C++, a video showing what code compiler generates when you write a lambda, article about why you should always capture exception by const reference and many others.

Professional C++ 4th Edition, Book Review

As usually, C++ needs good books and up-to-date learning resources. In this review, I’d like to present a book that should significantly enhance your knowledge of Modern C++, including C++17.

Let’s see what’s inside.

C++ Links #2

Welcome to new C++ Links - most important and useful articles, podcasts and videos that happened between 8th and 14th of September. Today you will find a link to a post about the C++ quality of life features, a video with an explanation of the difference between const and constexpr, an article that describes some of SFINAE problems and many others.

How To Use std::visit With Multiple Variants

How To Use std::visit with multiple variants

std::visit is a powerful utility that allows you to call a function over a currently active type in std::variant. It does some magic to select the proper overload, and what’s more, it can support many variants at once.

Let’s have a look at a few examples of how to use this functionality.

C++ Links #1

I'd like to make an experiment on the blog and introduce a new simple series. Each Friday you'll see a summary with valuable links and resources from the C++ World. The links and annotations are coming from a guest author - Wojciech Razik - one of the co-author of cpp-polska.pl.

Let's have a quick look at the best links for this week!

"C++17 In Detail" First Update

C++17 In Detail

I’m happy to announce that just a few days ago I updated the book! “C++17 In Detail” grew by 7 pages (up to 219), includes a few new examples, new feature descriptions and lots of “bug fixes”.

See what’s inside.

Preprocessing Phase for C++17's Searchers

C++17 searchers

Searchers from C++17 are a new way to perform efficient pattern lookups. The new standard offers three searchers: default_searcher , boyer_moore_searcher and boyer_moore_horspool_searcher. The last two implements algorithms that require some additional preprocessing for the input pattern. Is there a chance to separate preprocessing time from the search time?

Speeding up Pattern Searches with Boyer-Moore Algorithm from C++17

C++17 searchers

With C++17 you can now use more sophisticated algorithms for pattern searches! Now, you’ll have more control and a promising performance boost for many use cases.

See what the options are.

How to Initialize a String Member

How to init string member

How do you initialise a string member in the constructor? By using const string&, string value and move, string_view or maybe something else?

Let’s have a look at possible options.

Speeding Up string_view String Split Implementation

String_View Performance Followup

Thank you for all the comments about the string_view performance! Last week I got a lot of feedback on how to improve the initial string split code.

Have a look at how can we update the code and get some better performance.

Performance of std::string_view vs std::string from C++17

Using std::string_view from C++17

How much is std::string_view faster than standard std::string operations?

Have a look at a few examples where I compare std::string_view against std::string.

In-Place Construction for std::any, std::variant and std::optional

in place construction for C++17

When you read articles or reference pages for std::any, std::optional or std::variant you might notice a few helper types called in_place_* available in constructors.

Why do we need such syntax? Is this more efficient than “standard” construction?

Menu Class - Example of Modern C++17 STL features

Writing articles about modern C++ features is a lot of fun, but what’s even better is to see how you use those new things in real world.

Today I’m happy to present a guest post article from JFT who was so kind to describe his project where he uses several C++17 features.
He shared the process of building a menu that is based on std::any, std::variant and std::optional.

Have a look!
