# Event
### A C++20 Event system inspired by C# syntax.
![](https://img.shields.io/badge/Redacted-Software-black)
![Static Badge](https://img.shields.io/badge/Lit-Based-%20)
![C++](https://img.shields.io/badge/C%2B%2B-20-blue)
[![License: Unlicense](https://img.shields.io/badge/license-Unlicense-blue)](http://unlicense.org/)
## Features
* Fast
* (TODO: Profile!)
* Flexible
* Event delegate can be of any ![FunctionObject](https://en.cppreference.com/w/cpp/named_req/FunctionObject) type.
* Supports any set of parameters via templates.
* Easy To Use
* Written in portable and standard C++, no hacks or quirks.
* Utilizes Modern C++ features for elegant design.
* Zero dependencies. Fully self-contained.
* Unrestricted
* No GNU Copyleft communism. Totally Free & Public Domain.
## Coming Soon
* Event Filters / Policy
* Asynchronous
* Thread-Safe Version
* Priority Queue
* Auto disconnecting
## Supported Compilers
* GCC 14.2.1 (RedHat)
* MSVC 19.40
## Usage
This project is designed to be integrated via [CMake Package Manager](https://github.com/cpm-cmake/CPM.cmake).
```cmake
CPMAddPackage(
NAME Event
URL https://git.redacted.cc/josh/Event/archive/Release-7.zip
)
```
This snippet will automatically download a stable release of Event into your project's build directory, so it won't clutter your sources.
Take note of the release version and make sure it's the latest available in the Releases tab above.
```cmake
target_include_directories(${PROJECT_NAME} PUBLIC ${Event_SOURCE_DIR}/include)
target_link_libraries(${PROJECT_NAME} PUBLIC Event)
```
This snippet will import the headers, and then link the library to your library/executable. You should now be able to use Event.
The C++ snippet below reads input from the terminal and fires an event that received the input message.
```cpp
#include <Event.h>
#include <EventConnection.h>
void ReadMessage(const std::string& message) {
std::cout << "Received: " << message << std::endl;
}
int main()
{
Event<std::string> OnInput; // This and the declaration below are equivalent.
BasicEvent<std::function<void(std::string)>, std::string> OnInput2;
bool running = true;
while (running) {
std::string input;
std::cin >> input;
OnInput.Invoke(input);
OnInput(input); // Call operator is defined as well.
}
return 0;
}
More advanced examples can be found in the main.cpp file.
```
