co_yield expression expression allows it to write a generator function. The generator function returns a new value each time. A generator function is a kind of data stream from which you can pick values. The data stream can be infinite. Consequentially, we are in the center of lazy evaluation.

For your experiments, I used the following command line for all of the examples:-std=c++17: support for C++17-fcoroutines-ts: support for C++ coroutines TS-Iinclude: cppcoro headers Moreover, I have compiled above snipped using cppcoro library with clang 9.0.0 on wandbox. Boost Iterator Facade Design Pattern in C++ . If you have gone through my Facade Design Pattern article, you know that the first word in the above title i.e. Facade pronounces as `fa;sa;d`. New Added support for co_return and co_yield to Convert Between Pointer and Instance, Introduce Variable and Extract Method. (case=144111, 144110, 144109) New Added Code Inspection for performance-inefficient-vector-operation clang checker.

variable in C++11 named co_yield, and they could increment that variable by typing co_yield++. In this case, clang-format would change the formatting, despite the user never opting-in to treating co_yield as a keyword. (There are other examples of clang-format suddenly formatting C++11 code

A very rough view is that the call co_yield is replaced by the compiler calling yield_value.So promise_type_base serves as a container for the value coming from the coroutine into our normal code. All the other methods are just to satisfy the coroutine interface.

Clang: gnu standard library requires -fcoroutines but clang only supports -fcoroutines-ts

В этой статье мы подробно разберем понятие сопрограмм (coroutines), их классификацию, детально рассмотрим реализацию, допущения и компромиссы, предлагаемые новым стандартом C++20. Clang + llvm coroutines allows you to take this code: generator range(int from, int to) { for(int i = from; i < to; ++n) co_yield i; } int main() { int sum = 0; for (auto v: range(1,100)) sum += v; return sum; } And translate it down to this: define i32 @main() #5 { entry: This generator satisfies the co_yield interface of a coroutine. A very rough view is that the call co_yield is replaced by the compiler calling yield_value. So promise_type_base serves as a container for the value coming from the coroutine into our normal code.

Consequentially, we are in the center of lazy evaluation. When a compiler encounters co_await, co_yield or co_return in a function, it treats the function as a coroutine. By itself C++ does not define the semantics of the coroutine, a user or a library writer needs to provide a specialization of the std::experimental::coroutine_traits template that tells the compiler what to do.

Aug 17, 2017 For one thing, the co_yield keyword makes it trivial to define your own Put the above code in a .cpp file, compile with a recent clang and 

First of all, the main function can't be a coroutine. cppcoro::sync_wait (line 1) often serves, such as in this case, as a starting top-level task and waits, until the task finishes.
