Would be useful to see the implemented state machine if that's possible.

Hello Trass3r,

I agree. Funny thing, just yesterday I thought about this. I will have a look and see what I can do here.

Sorry, I'm testing stale bot and it does exactly the opposite of what I want. This issue will remain open.

Hi. @andreasfertig :)

Is there any progress with this ? Is it possible to contribute ? (nothing to show yet, just asking)

[andreasfertig]

Hello @grishavanika,

thanks for asking. Currently, I'm busy with a larger rewrite to transform even more code and to support generic lambdas. I have a private branch where I made some progress with coroutines. As they are now officially part of C++20 things are a bit easier (no additional option is required to activate them).

Examples of coroutines and how the transformed code looks like would help me. In general, I'm not sure how this transformation turns out and if it is helpful at all. However, I plan to approach some people more familiar with coroutines.

All that said, if you like to jump in I can push my development branch or you start something of your own.

See #92 (comment)
Sure just push the branch :)

[andreasfertig]

Hello @Trass3r,

I know that, thanks. I just like more data. Plus some things are not 100% clear to me. But, I have to check the branch, its been a while since I made changes to it. I will push it and let you know.

Hello all,

I just pushed my draft development branch. The entire branch is more or less just to show what new statements are available and tries to format them.

I'm not clear on:

• when and how a coroutine is allocated and how to visualize that.
• how to visualize the suspend and resume

Probably there are more things, but that is what I remember so far. Feel free to contribute.

Hello,

I wrote up a blog post about implementing coroutines in C++ Insights. There are quite some bummers. You can find it here andreasfertig.blog/2019/09/coroutines-in-c-insights.html. In addition to decide what to do I set up a Twitter poll you can take.
