Unify experimental includes #171

andreasbuhr · 2020-10-10T12:22:25Z

This pull request cares about three issues:

The #include <coroutine> vs. #include <experimental/coroutine> problem. A header is introduced which checks which include is available.
The std:: vs. std::experimental:: namespace issue. Coroutine related things a defined into the cppcoro:: namespace.
The same for filesystem vs experimental/filesystem

This pull request is based on the pull request #158 by @dutow. Thanks to @dutow for the great work.
Pull request 158 addresses several issues at the same time. I extracted this pull request which cares only about one single issue, in order to have an easy to review pull request.

To help improve this pull request, please fork https://github.com/andreasbuhr/cppcoro/tree/unify_experimental_includes and create a pull request toward this branch.

@andreasbuhr Something isn't right here, the PR says that you extracted parts of my pull request here, but in truth, all my commits (and @mmha 's commit too, and a few from you) is included in this PR, along with some merge commits.

If this pull request is only the experimental include fix, shouldn't it just be a single commit, the cherry-pick of 0b201f8?

andreasbuhr · 2020-10-10T12:34:57Z

Yes, you are right. I cherry-picked your whole pull request. I see three options:

Leave it like this, accepting clutter in the history.
Recreating this pull request as a cherry-pick of 0b201f8
Leave it like this, squashing it into one commit on merge.
What would you prefer?

dutow · 2020-10-10T12:38:45Z

You can also fix this PR by (with your unify_experimantal_includes branch checked out locally):

git reset --hard master
git cherry-pick 0b201f8
git push --force-with-lease

Starting with GCC 10.1, GCC/libstdc++ supports coroutines, but includes them in their final location in <coroutine>. This commit generalizes the location of the header, and the name of the types (either in the std or std::experimental namespace), so that both the current Clang/MSVC and the GCC approach can be supported. This should also guarantee that both current and later Clang/MSVC releases will be supported by the library.

The change for <coroutine> vs. <experimental/coroutine> is replicated for <filesystem> in this patch. In addition, the std::experimental namespace is replaced by cppcoro:: namespace in a few more places.

…includes

lewissbaker

Thanks! A couple of minor comments.
But otherwise looks good.

include/cppcoro/coroutine.hpp

+
+  using suspend_always = std::suspend_always;
+  using suspend_never = std::suspend_never;
+  static inline auto noop_coroutine() { return std::noop_coroutine(); }


Can this just be using std::noop_coroutine;?

Similarly for the other names?

using std::coroutine_handle; using std::suspend_always; using std::suspend_never; using std::noop_coroutine;

yes, this looks much better. Done.

I'll just squash the changes during the merge.

Thanks for making those changes.

This seems to break MSVC 2017 (and I think also some MSVC 2019 versions), which doesn't have noop_coroutine().

Maybe put this inside #if CPPCORO_COMPILER_SUPPORTS_SYMMETRIC_TRANSFER and add an include of <cppcoro/config.hpp>?

fixed now thx to @Garcia6l20

Unify experimental includes

This pull request is now open for two month. I now stop maintaining this pull request. From now on, I will continue to maintain the master branch in https://github.com/andreasbuhr/cppcoro. There we have CMake support, a CI based on Github Actions, and support for the latest compilers.
