🔇 Additional comments (16)
src/extensions/rppasio/rppasio/fwd.hpp (1)
14-16: LGTM: Documentation group name updated for consistency.The change from "RPPASIO" to "rppasio" in the documentation group name improves consistency in the casing style. This update enhances the overall coherence of the documentation without affecting the code functionality.
src/extensions/rppqt/rppqt/fwd.hpp (2)
14-16: LGTM: Documentation group name updateThe change from
@defgroup rppqt RPPQTto@defgroup rppqt rppqtimproves consistency in naming conventions. This aligns the group name with the actual module name, which is a good practice for maintaining clear and consistent documentation.
25-25: Verify compilation after include reorderingThe reordering of include statements, specifically moving
<rppqt/sources/fwd.hpp>after<rppqt/schedulers/fwd.hpp>, looks fine. This change might be to resolve dependencies or follow a specific include order convention.To ensure this change doesn't introduce any compilation issues, please run the following verification script:
If the script reveals any potential issues, please review and address them accordingly.
✅ Verification successful
Compilation Verification Successful

Line range hint
127-131: Approve: Improved accuracy in marble diagram representationThe change from
-1-xto-1-#in the marble diagram for the source observable is a positive improvement. This modification more accurately represents an error occurrence in the source observable, which is crucial for understanding theon_error_resume_nextoperator's behavior.In marble diagrams:
- '#' typically denotes an error
- 'x' usually represents a value emission
This update aligns the visual representation with the operator's description: "If an error occurs, take the result from the Selector and subscribe to that instead." It enhances the documentation's clarity without altering the actual functionality of the operator.
src/rpp/rpp/operators/retry.hpp (3)
142-143: Improved accuracy in marble diagram notationThe change from
xto#in the marble diagram enhances the accuracy of the documentation. The#symbol more precisely represents a termination signal (either completion or error) in standard marble diagram notation. This modification provides a clearer representation of theretryoperator's behavior, showing that it handles termination signals from the source observable.
166-166: Consistent update in infinite retry marble diagramThe change from
xto#in the source observable representation of the infinite retry operator's marble diagram is consistent with the previous update. It accurately depicts the termination signal from the source observable. The unchanged output representation (+-1-1-1-1-1-1-1-1-1-1-1->) correctly illustrates the behavior of an infinite retry, where the operator continues to resubscribe indefinitely upon receiving termination signals.
142-143: Summary: Documentation improvements for retry operatorsThe changes in this file focus on improving the accuracy and consistency of the marble diagrams for both the regular and infinite retry operators. By updating the termination signal representation from
xto#, the documentation now aligns better with standard marble diagram notation. These updates enhance the clarity of the operator's behavior documentation without affecting the underlying functionality. This change is in line with the PR objective of "Doxygen updates" and contributes to better overall documentation quality.Also applies to: 166-166
src/rpp/rpp/observables/observable.hpp (5)
92-93: LGTM: Parameter addition and documentation updateThe addition of the
obsparameter to thesubscribefunction and the corresponding documentation update are clear and consistent with the expected changes.
123-124: LGTM: Parameter addition and documentation updateThe addition of the
observer_strategyparameter to thesubscribefunction and the corresponding documentation update are clear and consistent with the expected changes.
247-249: LGTM: Parameter additions and documentation updateThe addition of
on_next,on_error, andon_completedparameters to thesubscribefunction and the corresponding documentation updates are clear and consistent with the expected changes. These additions enhance the flexibility of the subscription process by allowing separate handlers for different types of notifications.
285-287: LGTM: Parameter additions and documentation updateThe addition of
on_nextandon_completedparameters to this overload of thesubscribefunction and the corresponding documentation updates are clear and consistent with the expected changes. This overload provides a simpler interface for cases where explicit error handling is not required.
Line range hint
1-387: Overall assessment: Consistent and well-documented improvementsThe changes made to the
observableclass in this file consistently enhance its functionality by adding new parameters to various overloads of thesubscribefunction. These additions provide more flexibility in handling different aspects of the subscription process, such as specifying observers and individual handlers for next, error, and completed notifications.The documentation has been thoroughly updated to reflect these changes, maintaining the clarity and usability of the API. The consistency in changes across different overloads helps maintain a coherent interface for users of this class.
These improvements align well with the reactive programming paradigm and should enhance the overall usability of the library.

1051-1051: Appropriate exclusion of build directory.Excluding the 'build' directory from documentation generation is a good practice. It prevents unnecessary build artifacts from being included in the documentation, keeping it focused on the actual source code.
1142-1142: Verify the functionality of the marble diagram generator.The addition of a filter to process .hpp files with a Python script for generating marble diagrams is a good way to enhance the documentation. However, it's important to ensure that this script is working as expected.
#!/bin/bash # Check if the Python script exists and is executable if [ -f "./ci/generate_marbles.py" ] && [ -x "./ci/generate_marbles.py" ]; then echo "generate_marbles.py script found and is executable." else echo "Warning: generate_marbles.py script not found or not executable." fi # Check if any .hpp files contain marble diagram placeholders grep -rn --include="*.hpp" "MARBLE_DIAGRAM" .
1934-1934: Consider the implications of disabling LaTeX output.Disabling LaTeX output will reduce documentation generation time and output size. However, ensure that LaTeX output is not required for your project's documentation needs, as this format can be useful for generating high-quality printable documentation.
#!/bin/bash # Check if there are any explicit references to LaTeX documentation in the codebase grep -rn --include="*.hpp" --include="*.cpp" --include="*.md" -i "latex.*documentation" .
855-855: Consider the impact of disabling undocumented warnings.Setting
WARN_IF_UNDOCUMENTEDto NO will suppress warnings for undocumented entities. While this reduces the number of warnings, it may lead to incomplete documentation. Consider keeping this enabled to ensure comprehensive documentation coverage.

Tip For best results, initiate chat on the files or code changes. @victimsnino, I'd be happy to provide a detailed user guide and tutorial for ReactivePlusPlus, covering all the key components including observables, observers, operators, schedulers, and disposables, as well as explaining complex concepts in reactive functional programming. ReactivePlusPlus User Guide and TutorialIntroduction to Reactive ProgrammingReactive programming is a paradigm that focuses on asynchronous data streams and the propagation of change. It allows developers to build applications that are:
In reactive programming, data is modeled as streams that can be observed and processed. This approach is particularly powerful for handling real-time updates, user interactions, and asynchronous tasks. About ReactivePlusPlus (rpp)ReactivePlusPlus (rpp) is a modern C++20 library inspired by RxCpp and ReactiveX. It brings reactive programming to C++ with a focus on performance and ease of use. rpp provides a rich set of tools for working with asynchronous data streams, allowing developers to compose complex event-driven systems. Key Components:
Getting StartedInstallationClone the ReactivePlusPlus repository and include it in your project. git clone https://github.com/victimsnino/ReactivePlusPlus.gitInclude the necessary headers: #include <rpp/rpp.hpp>Ensure your project is set up to use C++20 features. Core ConceptsObservablesAn Observable emits a sequence of values over time. It acts as a data producer. Creating Observables
Subscribing to ObservablesTo receive items from an observable, an observer subscribes to it. observable.subscribe(
[](int value) { /* on_next handler */ },
[](std::exception_ptr e) { /* on_error handler */ },
[]() { /* on_completed handler */ }
);Example: observable.subscribe([](int value) {
std::cout << "Received: " << value << std::endl;
});Output: ObserversAn Observer consumes data emitted by an observable. It implements the following handlers:
Custom Observerauto observer = rpp::observer(
[](int value) {
std::cout << "Value: " << value << std::endl;
},
[](std::exception_ptr e) {
try {
std::rethrow_exception(e);
} catch (const std::exception& ex) {
std::cerr << "Error: " << ex.what() << std::endl;
}
},
[]() {
std::cout << "Completed" << std::endl;
}

Operator ChainingOperators can be chained to create complex data pipelines. Example: auto processed = rpp::source::range(1, 10)
.filter([](int value) { return value % 2 != 0; }) // Odd numbers
.map([](int value) { return value * value; }); // Squares
processed.subscribe([](int value) {

# ReactivePlusPlus Tutorial
[TOC]
## Introduction
Welcome to the comprehensive tutorial on **ReactivePlusPlus (RPP)**, a reactive programming library for C++20 inspired by RxCpp and ReactiveX. This tutorial will guide you through the concepts of reactive programming using RPP, including integration with Boost.Asio, Qt, and gRPC.
## What is Reactive Programming?
**Reactive Programming** is a programming paradigm centered around data streams and the propagation of change. It enables the development of asynchronous, event-driven applications that can respond to data changes and user inputs efficiently.
At its core, reactive programming deals with the following concepts:
- **Observable**: A data stream that emits data over time.
- **Observer**: A consumer that receives data from an Observable.
- **Operators**: Functions that enable functional-style composition and transformation of data streams.
- **Schedulers**: Components that control the threading and concurrency of data emissions.
Reactive programming allows developers to construct applications that are resilient, responsive, and scalable.
## Getting Started with ReactivePlusPlus
### Installation
To use ReactivePlusPlus in your project, follow these steps:
1. **Clone the Repository**
```bash
git clone https://github.com/victimsnino/ReactivePlusPlus.git-
Build the Library
cd ReactivePlusPlus mkdir build && cd build cmake .. make
-
Include in Your Project
Add the following to your CMakeLists.txt:
find_package(RPP REQUIRED) target_link_libraries(your_target PRIVATE RPP::rpp)
Ensure that you include the RPP headers in your source files:
#include <rpp/rpp.hpp>
Basic Concepts
Observable
An Observable emits a sequence of items over time. It can be finite or infinite and can emit zero or more items, followed by either a completion or an error signal.
Observer
An Observer subscribes to an Observable to receive emissions. It defines how to handle each item, errors, and completion notifications.
Subscription
A Subscription represents the connection between an Observer and an Observable. It can be used to unsubscribe and stop receiving emissions.
Operator
An Operator is a function that transforms or modifies the data emitted by an Observable, allowing you to compose complex data flows.
Scheduler
A Scheduler determines the threading model for the Observables and Observers, controlling concurrency.
Basic Usage
Creating an Observable and Observer
#include <rpp/rpp.hpp>
#include <iostream>
int main() {
auto observable = rpp::source::just(1, 2, 3);
auto observer = rpp::make_lambda_observer(
[](int value) { std::cout << "Received: " << value << std::endl; },
[](std::exception_ptr) { std::cout << "Error occurred." << std::endl; },
[]() { std::cout << "Completed." << std::endl; }
);
observable.subscribe(observer);
return 0;
}Output:
Received: 1
Received: 2
Received: 3
Completed.
Using Operators
Map Operator
Transforms each item emitted by an Observable.
auto observable = rpp::source::just(1, 2, 3)
| rpp::operators::map([](int value) { return value * 10; });
observable.subscribe([](int value) {
std::cout << "Transformed Value: " << value << std::endl;
});Output:
Transformed Value: 10
Transformed Value: 20
Transformed Value: 30
Filter Operator
Emits only those items from an Observable that pass a predicate test.
auto observable = rpp::source::just(1, 2, 3, 4, 5)
| rpp::operators::filter([](int value) { return value % 2 == 0; });
observable.subscribe([](int value) {
std::cout << "Even Value: " << value << std::endl;
});Output:
Even Value: 2
Even Value: 4
Advanced Concepts
Combining Observables
Merge Operator
Combines multiple Observables into one by merging their emissions.
auto observable1 = rpp::source::just(1, 3, 5);
auto observable2 = rpp::source::just(2, 4, 6);
auto merged = observable1 | rpp::operators::merge_with(observable2);
merged.subscribe([](int value) {
std::cout << "Merged Value: " << value << std::endl;
});Output (order may vary):
Merged Value: 1
Merged Value: 2
Merged Value: 3
Merged Value: 4
Merged Value: 5
Merged Value: 6
Zip Operator
Combines emissions from multiple Observables by pairing emissions of the same index.
auto observable1 = rpp::source::just(1, 2, 3);
auto observable2 = rpp::source::just("A", "B", "C");
auto zipped = rpp::source::zip(observable1, observable2);
zipped.subscribe([](const std::tuple<int, std::string>& value) {
std::cout << "Zipped Value: " << std::get<0>(value) << ", " << std::get<1>(value) << std::endl;
});Output:
Zipped Value: 1, A
Zipped Value: 2, B
Zipped Value: 3, C
Error Handling
Handle errors gracefully using the on_error handler.
auto observable = rpp::source::create<int>([](const auto& observer) {
observer.on_next(42);
observer.on_error(std::make_exception_ptr(std::runtime_error("Oops!")));
});
observable.subscribe(
[](int value) { std::cout << "Received: " << value << std::endl; },
[](std::exception_ptr eptr) {
try {
std::rethrow_exception(eptr);
} catch (const std::exception& e) {
std::cout << "Error: " << e.what() << std::endl;
}
},
[]() { std::cout << "Completed." << std::endl; }
);Output:
Received: 42
Error: Oops!
Multithreading and Schedulers
Using Schedulers
Schedulers control the execution context (threading) of Observables.
subscribe_on
Specifies the scheduler on which an Observable will begin emitting items.
auto observable = rpp::source::just(1, 2, 3)
| rpp::operators::subscribe_on(rpp::schedulers::new_thread{});
observable.subscribe([](int value) {
std::cout << "Received on thread " << std::this_thread::get_id() << ": " << value << std::endl;
});observe_on
Specifies the scheduler on which an Observer will observe the emissions.
auto observable = rpp::source::just(1, 2, 3)
| rpp::operators::observe_on(rpp::schedulers::new_thread{});
observable.subscribe([](int value) {
std::cout << "Observed on thread " << std::this_thread::get_id() << ": " << value << std::endl;
});Integration with Boost.Asio
Boost.Asio is a cross-platform C++ library for network and low-level I/O programming.
Asynchronous Networking with RPP and Asio
#include <rpp/rpp.hpp>
#include <boost/asio.hpp>
#include <iostream>
int main() {
boost::asio::io_context io_context;
auto timer_observable = rpp::source::create<void>([&](const auto& observer) {
boost::asio::steady_timer timer(io_context, std::chrono::seconds(1));
timer.async_wait([observer](const boost::system::error_code& ec) {
if (!ec) {
observer.on_next();
observer.on_completed();
} else {
observer.on_error(std::make_exception_ptr(boost::system::system_error(ec)));
}
});
});
timer_observable.subscribe(
[]() { std::cout << "Timer expired!" << std::endl; },
[](std::exception_ptr eptr) {
try {
std::rethrow_exception(eptr);
} catch (const std::exception& e) {
std::cout << "Error: " << e.what() << std::endl;
}
}
);
io_context.run();
return 0;
}Explanation:
- We create an Observable that emits when a
boost::asio::steady_timerexpires. - The Observable notifies the Observer upon timer completion or error.
Integration with Qt
Qt is a widely used framework for building GUI applications.
Reactive GUI Events with RPP and Qt
#include <rpp/rpp.hpp>
#include <QApplication>
#include <QPushButton>
#include <iostream>
int main(int argc, char* argv[]) {
QApplication app(argc, argv);
QPushButton button("Click Me!");
button.show();
auto click_observable = rpp::source::create<void>([&](const auto& observer) {
QObject::connect(&button, &QPushButton::clicked, [&observer]() {
observer.on_next();
});
});
click_observable.subscribe([]() {
std::cout << "Button was clicked!" << std::endl;
});
return app.exec();
}Explanation:
- We create an Observable that emits every time the button is clicked.
- The Observer reacts by printing a message to the console.
Integration with gRPC
gRPC is a high-performance framework that can use reactive streams for client-server communication.
Streaming RPCs with RPP and gRPC
#include <rpp/rpp.hpp>
#include <grpcpp/grpcpp.h>
#include "your_service.grpc.pb.h"
#include <iostream>
int main() {
auto channel = grpc::CreateChannel("localhost:50051", grpc::InsecureChannelCredentials());
auto stub = YourService::NewStub(channel);
grpc::ClientContext context;
YourRequest request;
auto reader = stub->YourStreamingRPC(&context, request);
auto stream_observable = rpp::source::create<YourResponse>([&](const auto& observer) {
YourResponse response;
while (reader->Read(&response)) {
observer.on_next(response);
}
grpc::Status status = reader->Finish();
if (status.ok()) {
observer.on_completed();
} else {
observer.on_error(std::make_exception_ptr(std::runtime_error(status.error_message())));
}
});
stream_observable.subscribe(
[](const YourResponse& response) { std::cout << "Received response." << std::endl; },
[](std::exception_ptr eptr) {
try {
std::rethrow_exception(eptr);
} catch (const std::exception& e) {
std::cout << "gRPC Error: " << e.what() << std::endl;
}
},
[]() { std::cout << "Stream completed." << std::endl; }
);
return 0;
}Explanation:
- We create an Observable that emits responses from a gRPC streaming RPC.
- The Observer handles each response, any errors, and stream completion.
Creating Custom Operators
Extend RPP by creating your own operators to encapsulate reusable logic.
Example: delay
A custom operator that delays emissions by a specified duration.
template<typename Duration>
auto delay(Duration duration) {
return [duration](const auto& observable) {
using T = typename decltype(observable)::value_type;
return rpp::source::create<T>([observable, duration](const auto& observer) {
observable.subscribe(
[observer, duration](const T& value) {
std::this_thread::sleep_for(duration);
observer.on_next(value);
},
[observer](std::exception_ptr eptr) { observer.on_error(eptr); },
[observer]() { observer.on_completed(); }
);
});
};
}Usage:
auto delayed_observable = rpp::source::just(1, 2, 3)
| delay(std::chrono::seconds(1));
delayed_observable.subscribe([](int value) {
std::cout << "Received after delay: " << value << std::endl;
});Output:
Emits each value with a 1-second delay.
Thread Safety and Synchronization
RPP ensures that emissions are serial, adhering to the Observable contract. However, when dealing with shared resources or state, you should manage synchronization appropriately.
Example: Protecting Shared State
#include <mutex>
std::mutex mtx;
int shared_counter = 0;
auto observable = rpp::source::create<int>([](const auto& observer) {
for (int i = 0; i < 5; ++i) {
observer.on_next(i);
}
observer.on_completed();
})
| rpp::operators::subscribe_on(rpp::schedulers::new_thread{});
observable.subscribe([](int value) {
std::lock_guard<std::mutex> lock(mtx);
shared_counter += value;
std::cout << "Shared Counter: " << shared_counter << std::endl;
});Memory Management
RPP provides options for managing memory models to optimize performance.
Using Memory Models
- Use Stack: For small objects that are inexpensive to copy.
- Use Shared: For larger objects where copying is expensive.
Example:
auto observable = rpp::source::just<rpp::memory_model::use_shared>(my_large_object);Exception Handling and Guarantees
Exceptions are communicated via the on_error callback. RPP ensures that subscribers are notified of any errors, and resources are cleaned up appropriately.

auto observable2 = rpp::source::just("A", "B", "C");
auto zipped = rpp::source::zip(observable1, observable2);
zipped.subscribe([](const std::tuple<int, std::string>& value) {
std::cout << "Zipped Value: " << std::get<0>(value) << ", " << std::get<1>(value) << std::endl;
});Output:
Zipped Value: 1, A
Zipped Value: 2, B
Zipped Value: 3, C
Error Handling
Handle errors gracefully using the on_error handler.
auto observable = rpp::source::create<int>([](const auto& observer) {
observer.on_next(42);
observer.on_error(std::make_exception_ptr(std::runtime_error("Oops!")));
});
observable.subscribe(
[](int value) { std::cout << "Received: " << value << std::endl; },
[](std::exception_ptr eptr) {
try {
std::rethrow_exception(eptr);
} catch (const std::exception& e) {
std::cout << "Error: " << e.what() << std::endl;
}
},
[]() { std::cout << "Completed." << std::endl; }
);Output:
Received: 42
Error: Oops!
Multithreading and Schedulers
Using Schedulers
Schedulers control the execution context (threading) of Observables.
subscribe_on
Specifies the scheduler on which an Observable will begin emitting items.
auto observable = rpp::source::just(1, 2, 3)
| rpp::operators::subscribe_on(rpp::schedulers::new_thread{});
observable.subscribe([](int value) {
std::cout << "Received on thread " << std::this_thread::get_id() << ": " << value << std::endl;
});observe_on
Specifies the scheduler on which an Observer will observe the emissions.
auto observable = rpp::source::just(1, 2, 3)
| rpp::operators::observe_on(rpp::schedulers::new_thread{});
observable.subscribe([](int value) {
std::cout << "Observed on thread " << std::this_thread::get_id() << ": " << value << std::endl;
});Integration with Boost.Asio
Boost.Asio is a cross-platform C++ library for network and low-level I/O programming.
Asynchronous Networking with RPP and Asio
#include <rpp/rpp.hpp>
#include <boost/asio.hpp>
#include <iostream>
int main() {
boost::asio::io_context io_context;
auto timer_observable = rpp::source::create<void>([&](const auto& observer) {
auto timer = std::make_shared<boost::asio::steady_timer>(io_context, std::chrono::seconds(1));
timer->async_wait([observer, timer](const boost::system::error_code& ec) {
if (!ec) {
observer.on_next();
observer.on_completed();
} else {
observer.on_error(std::make_exception_ptr(boost::system::system_error(ec)));
}
});
});
timer_observable.subscribe(
[]() { std::cout << "Timer expired!" << std::endl; },
[](std::exception_ptr eptr) {
try {
std::rethrow_exception(eptr);
} catch (const std::exception& e) {
std::cout << "Error: " << e.what() << std::endl; }
}
);
io_context.run();
return 0;
}Explanation:
- We create an Observable that emits when a
boost::asio::steady_timerexpires. - The Observable notifies the Observer upon timer completion or error.
Integration with Qt
Qt is a widely used framework for building GUI applications.
Reactive GUI Events with RPP and Qt
#include <rpp/rpp.hpp>
#include <QApplication>
#include <QPushButton>
#include <iostream>
int main(int argc, char* argv[]) {
QApplication app(argc, argv);
QPushButton button("Click Me!");
button.show();
auto click_observable = rpp::source::create<void>([&](const auto& observer) {
QObject::connect(&button, &QPushButton::clicked, [&observer]() {
observer.on_next();
});
});
click_observable.subscribe([]() {
std::cout << "Button was clicked!" << std::endl;
});
return app.exec();
}Explanation:
- We create an Observable that emits every time the button is clicked.
- The Observer reacts by printing a message to the console.
Integration with gRPC
gRPC is a high-performance framework that can use reactive streams for client-server communication.
Streaming RPCs with RPP and gRPC
#include <rpp/rpp.hpp>
#include <grpcpp/grpcpp.h>
#include "your_service.grpc.pb.h"
#include <iostream>
int main() {
auto channel = grpc::CreateChannel("localhost:50051", grpc::InsecureChannelCredentials());
auto stub = YourService::NewStub(channel);
grpc::ClientContext context;
YourRequest request;
auto reader = stub->YourStreamingRPC(&context, request);
auto stream_observable = rpp::source::create<YourResponse>([&](const auto& observer) {
YourResponse response;
while (reader->Read(&response)) {
observer.on_next(response);
}
grpc::Status status = reader->Finish();
if (status.ok()) {
observer.on_completed();
} else {
observer.on_error(std::make_exception_ptr(std::runtime_error(status.error_message())));
}
});
stream_observable.subscribe(
[](const YourResponse& response) { std::cout << "Received response." << std::endl; },
[](std::exception_ptr eptr) {
try {
std::rethrow_exception(eptr);
} catch (const std::exception& e) {
std::cout << "gRPC Error: " << e.what() << std::endl;
}
},
[]() { std::cout << "Stream completed." << std::endl; }
);
return 0;
}Explanation:
- We create an Observable that emits responses from a gRPC streaming RPC.
- The Observer handles each response, any errors, and stream completion.
Creating Custom Operators
Extend RPP by creating your own operators to encapsulate reusable logic.
Example: delay
A custom operator that delays emissions by a specified duration.
template<typename Duration>
auto delay(Duration duration) {
return [duration](const auto& observable) {
using T = typename decltype(observable)::value_type;
return rpp::source::create<T>([observable, duration](const auto& observer) {
observable.subscribe(
[observer, duration](const T& value) {
std::this_thread::sleep_for(duration);
observer.on_next(value);
},
[observer](std::exception_ptr eptr) { observer.on_error(eptr); },
[observer]() { observer.on_completed(); }
);
});
};
}Usage:
auto delayed_observable = rpp::source::just(1, 2, 3)
| delay(std::chrono::seconds(1));
delayed_observable.subscribe([](int value) {
std::cout << "Received after delay: " << value << std::endl;
});Output:
Emits each value with a 1-second delay.
Thread Safety and Synchronization
RPP ensures that emissions are serial, adhering to the Observable contract. However, when dealing with shared resources or state, you should manage synchronization appropriately.
Example: Protecting Shared State
#include <mutex>
std::mutex mtx;
int shared_counter = 0;
auto observable = rpp::source::create<int>([](const auto& observer) {
for (int i = 0; i < 5; ++i) {
observer.on_next(i);
}
observer.on_completed();
})
| rpp::operators::subscribe_on(rpp::schedulers::new_thread{});
observable.subscribe([](int value) {
std::lock_guard<std::mutex> lock(mtx);
shared_counter += value;
std::cout << "Shared Counter: " << shared_counter << std::endl;
});Memory Management in RPP
RPP provides options for managing memory models to optimize performance.
Using Memory Models
- Use Stack: For small objects that are inexpensive to copy.
- Use Shared: For larger objects where copying is expensive.
Example:
auto observable = rpp::source::just<rpp::memory_model::use_shared>(my_large_object);Exception Handling and Guarantees
Exceptions are communicated via the on_error callback. RPP ensures that subscribers are notified of any errors, and resources are cleaned up appropriately.
Conclusion
This tutorial covered the fundamentals of reactive programming using ReactivePlusPlus, including integration with Boost.Asio, Qt, and gRPC. With RPP, you can build robust, scalable, and responsive applications in modern C++.
We encourage you to explore the library further, contribute to its development, and become part of the ReactivePlusPlus community.
Is there anything else you'd like me to add or adjust?

839-839: Consider the trade-offs of enabling QUIET mode.Enabling QUIET mode (YES) will suppress standard output messages during documentation generation. This can be beneficial in CI/CD pipelines or automated processes. However, be aware that it might hide useful information during manual runs.
Consider adding a comment explaining the reason for this change, especially if it's intended for a specific use case (e.g., "Enabled for CI/CD pipeline integration").
855-855: Be cautious about disabling undocumented warnings.Disabling WARN_IF_UNDOCUMENTED (NO) will suppress warnings about undocumented members. While this can reduce noise in the output, especially for large projects, it might lead to overlooking important documentation gaps.
Consider adding a TODO comment to re-enable this in the future once the documentation coverage has improved, or explain the rationale behind this decision.
870-870: Consider the implications of disabling incomplete documentation warnings.Disabling WARN_IF_INCOMPLETE_DOC (NO) will suppress warnings about incomplete function parameter documentation. This can reduce noise in the output, but it might lead to overlooking important documentation gaps, potentially affecting the overall quality of the documentation.
Consider adding a comment explaining the rationale behind this decision, or set a reminder to re-evaluate this setting in the future to ensure documentation completeness.
1142-1142: Good update: Explicitly using Python 3 for file processing.Updating FILTER_PATTERNS to use "python3" instead of "python" is a good change. This ensures that Python 3 is used for processing .hpp files, which is important if the script relies on Python 3 features or if the system's default Python is version 2.
Consider adding a comment explaining why Python 3 is required, especially if there are specific version dependencies or features being used in the processing script.

1-2070: Overall, the Doxyfile changes improve configuration for specific use cases.The modifications to the Doxygen configuration file appear to be intentional and address specific project needs. Key changes include:
- Enabling quiet mode for cleaner output in automated processes.
- Disabling certain warnings to reduce noise, particularly for undocumented or incompletely documented elements.
- Excluding the build directory to prevent processing of build artifacts.
- Explicitly using Python 3 for file processing.
While these changes can improve the documentation generation process, be mindful of the potential long-term effects on documentation quality, especially regarding the disabled warnings.

Correct possessive pronoun usage
There's a grammatical error in this line:
- **set_upstream(disposable)** - observable could pass to observer it's own disposable to provide ability for observer to terminate observable's internal actions/state
+ **set_upstream(disposable)** - observable could pass to observer its own disposable to provide ability for observer to terminate observable's internal actions/stateThe possessive pronoun "its" should be used here instead of the contraction "it's" (which means "it is").

Missing HTML_HEADER Configuration for doxygen-awesome-css
While the HTML_EXTRA_STYLESHEET is correctly set to include doxygen-awesome-css, the HTML_HEADER is not configured to use the doxygen-awesome-css theme. This may result in incomplete theming of your Doxygen documentation.
- File to Update:
Doxyfile - Add or Verify the Following Line:
HTML_HEADER = docs/doxygen-awesome-css/header.html
Ensure that the HTML_HEADER points to the correct header file within the doxygen-awesome-css submodule to fully integrate the theme.

Reconsider disabling inheritance graphs for all classes.
The inheritance graph visibility has been set to "no" for all classes. While this can reduce clutter for simple classes, it might hide valuable information for complex class hierarchies.
Consider a more flexible approach:
- Keep the original
$CLASS_GRAPHvariable to allow per-project configuration. - Use a threshold (e.g., minimum number of derived classes) to determine when to show the graph.
- Provide a way to enable/disable graphs for specific classes using special comments.

Clarify the purpose of adding properties to namespaces.
Properties have been added to both the memberdecl and memberdef sections of the namespace layout. This is unusual for C++ namespaces, which typically don't have properties.
Please clarify:
- What types of elements are intended to be documented as "properties" within namespaces?
- Is this meant to document static members or global variables within namespaces?
- If this is not applicable to C++ namespaces, consider removing these entries to avoid confusion.

51-55: Improved comparison with existing libraries.
The rephrasing of this section provides a clearer and more balanced comparison of ReactivePlusPlus with existing Reactive Extension libraries. The corrections address previous review comments and enhance the overall readability.
However, there's a minor typo that needs correction:
- While RxCpp is a great and powerful library, it has some disadvantages. It is written in C++11 and contains parts written in pre-C++11 style. This leads to a mess of old-style classes and wrappers. Additionally, the `rxcpp::observable` type has a long chain of template parameters, which can lead to slower IDE performance and larger binaries. Sometimes it has bad performance due to tremendous amount of usage of heap or just non-effective logic.

The inclusion of minimum compiler requirements is an excellent addition to the Usage section. It clearly communicates the C++20 dependency and helps users quickly determine if their development environment is compatible.
Consider adding a link to the C++20 feature support page for each compiler, which would help users verify their compiler's compatibility in more detail.
