nim-in-action-code

This is cool and reminds me of the Twitter clone[1] I included as a coding exercise in my book[2]. It's a very good way to learn as a basic Twitter clone is relatively simple to implement. 1 - https://github.com/dom96/nim-in-action-code/tree/master/Chap... 2 - https://book.picheta.me

https://github.com/dom96/nim-in-action-code/blob/master/Chap... Does the linked line imply that a slow client will block the rest of the clients from receiving new messages?

The story is that it's used in production and works quite well (but I am pretty biased as I developed most of it). If you want some examples take a look at my book[1] which includes a whole chapter where you build a chat app using Nim's async/await. The code for this is freely available[2]. 1 - https://book.picheta.me/ 2 - https://github.com/dom96/nim-in-action-code

Here is a C++ wrapper for SFML that I made, you can use it as an example: https://github.com/dom96/nim-in-action-code/tree/master/Chap... You can also try using `c2nim`'s cpp mode.

Yep. Concurrency is achieved via async await. Parallelism via `spawn`. Here is an example from my book that uses both: https://github.com/dom96/nim-in-action-code/blob/master/Chap...

You're very right to doubt me. But it does make it easy, Nim compiles to C/C++/Objective C (exceptions are mapped to C++ exceptions in C++ mode). This gives it the ability to wrap all C++ libraries, Nim takes advantage of this to make wrapping easy, here is a (very) barebones wrapper for sfml as an example: https://github.com/dom96/nim-in-action-code/blob/master/Chap...

It extends to Nim, and macros can also receive any valid Nim token. Alternatively you can also pass a string literal and parse it in your macro. Nim's metaprogramming support is quite extensive, possibly even more so than Rust's. If this is something that interests you then you should check it out. As an example of what's possible: async await in Nim is implemented entirely via a macro[1], the `=>` operator for closures is also implemented as a macro[2]. 1 - Example chat app client using async await: https://github.com/dom96/nim-in-action-code/blob/master/Chap... 2 - Implementation of `=>`: https://github.com/nim-lang/Nim/blob/devel/lib/pure/future.n...
