Book “C++ Lambda Story”
A friend of mine published a new book, titled “C++ Lambda Story”. The book explains everything you need to know about lambda expressions in C++.
The book guides you through the evolution of C++ Lambda Expressions so that you can learn it step by step. It starts with C++03 and a motivation to have “ad-hoc” functors, and then moves into the latest C++ standards:
- C++11 – early days of the feature. You’ll learn about all the essential aspects of lambdas and several tricks you might apply. This is the longest chapter as it needs to cover a lot of topics.
- C++14 – updates. See how to use generic lambdas and captures with an initializer.
- C++17 – more improvements, especially by handling ‘this’ pointer and allowing ‘constexpr’. You’ll also learn about the overloaded pattern and how to derive from lambda.
- C++20 – in this section you’ll see all of the new features adopted for C++20 like template lambdas and how to use them with concepts and constexpr algorithms.
Additionally, throughout the chapters, you’ll learn about the following techniques:
- Immediately Invoked Functional Expressions (IIFE)
- How to instrument a default functor to gather extra information
- Replacing std::bind1st, std::bind2nd and removed functional stuff
- The Overloaded Pattern and how to inherit from a lambda
- Passing C++ captureless lambda as a function pointer to C API
- LIFTING with lambdas
- Storing lambdas in a container
- Variadic templates and arguments packs
- Lambdas and asynchronous execution
- and many more
