Is this a header-only library?
It seems that the repo is an unofficial website. Could you please use an official one?

[RT2Code]

Yes, this is a header only library.

I don't understand what you mean about the unofficial website. jthread is an upcoming feature from the new C++20 standard not currently available in Visual Studio, which is why I made this port. It was proposed by Nicolai Josuttis and I'm using the repository where he submitted his implementation of it.

From : https://medium.com/@vgasparyan1995/a-new-thread-in-c-20-jthread-ebd121ae8906

Even though it comes with C++20, std::jthread doesn’t use any of the new language features, so it’s practically available even now. Here is an implementation of it by Nicolai Josuttis, the person who proposed it. Two header files from this repository are all you need to fully access this new feature: “jthread.hpp” and “stop_token.hpp” in “sources/”.

@RT222 Thanks for your detailed information.
Sorry, I mistook this port as JThread https://github.com/j0r1/JThread. I thought they were the same library before.
You can ignore my last comment about official website. The URL you provided seems fine.

Given that there are two libraries named jthread, this name is probably too generic; could you rename this josuttis-jthread?

[RT2Code]

Isn't jthread for this one, and j0r1-jthread for the other one that you mentioned better? As the former is the implementation of the upcoming C++ 20 feature of the same name, I think it is the most appropriate candidate to be simply named jthread.

[strega-nil]

Since this library is no more "official" than any other jthread library, it's totally reasonable for anyone to release a jthread library and call it jthread. Since that is the case, it makes more sense to me to namespace it with the author's name.

[RT2Code]

I made the change you asked, but I still disagree with the "no more official" part, given that we are talking about the reference implementation of a standard C++ feature on a C++ package manager. :(

@RT222 I get your opinion; thanks for listening anyways ❤️
