I have uploaded it to personal conan-repository(https://fish.jfrog.io/artifactory/api/conan/fish-conan), dependence: QtPromise/master
TODO:
1, Need to add test_package for testing
2, Need to upload to conan-center, better with ci/cd
Converts the resolved value of `QPromise<T>` to the type `U`. Depending on types `T` and `U`, it performs a static cast, calls a converting constructor or tries to convert using `QVariant`.
- Use std::invoke_result, fallback to std::result_of on C++11/14.
- Use RVO instead of std::move (GCC warning: redundant-move).
- Replace QSharedPointer with std::shared_ptr (GCC warning: unititialized value).
- QLinkedList is deprecated in Qt 5.15.
Broken since 78417b5, this bug creates an infinite recursion at runtime while trying to resolve the QPromise<T> template constructor if the given callback is either an invalid function or a valid callback but using auto args (C++14).
Related warning: C4717: recursive on all control paths, function will cause runtime stack overflow.
Based on the WebKit preset and following 'most' of the Qt guidelines, except a few rules that work better for promise continuation lambdas. Requires clang-format 11.

- Add links validation to `npm run docs:link`.
- Reorganize the sidebar API Reference section.
- Add npm package.json to make easier maintaining dependencies.
- Make markdown files consistent using remark.
- Wrap markdown lines to 100 characters.
- Better README.md layout and visual.
- Enable VuePress landing/home page.
- Upgrade to latest VuePress version.
- Add link to the new Qt Marketplace.
Iterates over all the promise values (i.e. `Sequence<T>`) and reduces the sequence to a single value using the given `reducer` function and an optional `initialValue`. Also provide a static helper to directly reduce values (`QtPromise::reduce(values, reducer, initialValue)`).
For consistency with other helpers, deprecate `qPromise()` in favor of `QtPromise::resolve()` but also add support for calling this helper with lvalue. Add extra unit tests to make sure that rvalue is not copied.
Introduce a new `QtPromise::connect()` helper that allows to create a promise resolved from a single signal and optionally, rejected by another one (from a different object or not). The promise type is determined by the type of the first signal argument (other arguments are currently ignored). A `QPromise<void>` is returned if the resolve signal doesn't provide any argument.
If the rejection is emitted before the promise is resolved, the promise will be rejected with the value of the first argument (other arguments being ignored). If the rejection signal doesn't provide any argument, the promise will be rejected with `QPromiseUndefinedException` if the signal is emitted. Additionally, the promise will be automatically rejected with `QPromiseContextException` if the source object is destroyed before the promise is resolved.
While not recommended because it makes tracking errors more difficult, it's now possible to reject a promise without explicit reason, in which case, a built-in `QPromiseUndefinedException` is thrown. This is done in anticipation of handling rejection signals without argument.
GitBook development seems a bit stuck right now so let's switch to VuePress which, IMO, is more user friendly. Update the documentation to include the version number in which features were added and use custom container to display notes and warnings.
Call the given `functor` on each element in the promise value (i.e. `Sequence<T>`), then resolve to the original sequence unmodified. Also provide a static helper to directly filter values (`QtPromise::each(values, functor)`).
Add a new helper that calls functor immediately and returns a promise fulfilled with the value returned by functor. Any synchronous exceptions will be turned into rejections on the returned promise. This is a convenient method that can be used instead of handling both synchronous and asynchronous exception flows.
Also simplify PromiseDispatch which now calls the functor with a variable number of arguments (including none).
