e3f0f054af Implement QPromise<Sequence<T>>::reduce(reducer, initialValue)
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)`).

963ec621e1 Rename qPromise() helper to QtPromise::resolve()
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.

1f30224578 Add support for creating promises from Qt signals (#25)
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.

fa5a4192ff Allow undefined rejection reason
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.

eebcb4f364 Migrate documentation to VuePress
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.

051fed5fbc Implement QPromise<Sequence<T>>::each(functor)
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)`).

f610826ef0 Implement QtPromise::attempt(functor, args...)
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).

4fa7a37750 Implement QPromise<Sequence<T>>::filter(filterer)
Add a new method that iterates over all the promise values (i.e. `Sequence<T>`) and filters the sequence to another using the given `filterer` function. If `filterer` returns `true`, a copy of the item is put in the `output` sequence, otherwise, the item will not appear in `output`. Also provide a static helper to directly filter values (`QtPromise::filter(values, filterer)`).

fa987a5044 Cleanup promise captured in resolve/reject
Make sure that QPromiseResolve and QPromiseReject release their associated promise as soon as one of them is resolved or rejected, ensuring that the promise data is cleaned up once resolved (that fixes cases where one or both of them are captured in a signal/slot connection lambda)

313d3882d7 Fix dispatching when app (or thread) terminated
Make sure to **not** notify handlers if the captured thread doesn't exist anymore, which would potentially result in dispatching to the wrong thread (ie. nullptr == current thread). This also applies when the app is shutting down and the even loop is not anymore available. In both cases, we should not trigger any error and skip notifications.

18739bd8e0 New documentation based on GitBook CLI
Split the root README.md in multiple Markdown files (in the `docs/` folder) to make easier reading, editing and extending the documentation. An online version is also available on netlify (https://qtpromise.netlify.com). Building it requires Node.js installed, then:

- npm install -g gitbook-cli
- gitbook install ./
- gitbook build . dist/docs

c34316243e Make QPromise::all accept more container types
Currently, QPromise can't be added dynamically to QVector (::push_* | ::append) because it doesn't expose a default constructor. Until deciding if a default constructor should be added (private/public?), let's make the `QPromise::all` method work with any container types that are STL compatible.

b47ca0569e Implement QPromise::delay(msec)
This method returns a promise that will be fulfilled with the same value as the `input` promise and after at least `msec` milliseconds. If the `input` promise is rejected, the `output` promise is immediately rejected with the same reason.

c55fa03e7b Implement QPromise::tap(handler)
This `handler` allows to observe the value of the `input` promise, without changing the propagated value. The `output` promise will be resolved with the same value as the `input` promise (the `handler` returned value will be ignored). However, if `handler` throws, `output` is rejected with the new exception. Unlike `finally`, this handler is not called for rejections.

25d2bad54f Enhance QPromise::finally implementation
Make sure that the chained value is not copied when `finally` is called for a fulfilled input promise. The value was copied 7 times in the previous version because it was captured in a lambda, which one copied multiple times.
