Tsig is a Work In Progress.
Minimal signals in C++11. Inspired by more complex signals and slots systems like Qt and Boost.Signals2, Tsig implements minimal signals in a single header file, depending only on the standard library.
void DoSomethingA(int x, int y) {
std::cout << "[A] Hello " << x << ", " << y << "\n";
}
struct DoerOfSomethingB {
void operator()(int x, int y) const {
std::cout << "[B] Hello " << x << ", " << y << "\n";
}
};
auto do_something_c = [](int x, int y) {
std::cout << "[C] Hello " << x << ", " << y << "\n";
};
Signal<void(int, int)> signal;
// Connect handlers to make sigcons (signal connections)
auto sigcon_a = signal.Connect(DoSomethingA);
auto sigcon_b = signal.Connect(DoerOfSomethingB());
auto sigcon_c = std::make_shared<Sigcon>(signal.Connect(do_something_c));
// Emit to call all handlers
signal.Emit(1, 2);
// Output:
// [A] Hello 1, 2
// [B] Hello 1, 2
// [C] Hello 1, 2
// Reset or destruct sigcons to remove handlers
sigcon_b.Reset();
sigcon_c = nullptr;
// This will only call the 'A' handler
signal.Emit(3, 4);
// Output:
// [A] Hello 3, 4The build uses Meson and Ninja. You will need to install those. On Ubuntu you can probably run something like:
$ sudo apt-get install python3-pip ninja-build
$ sudo pip3 install meson
Once the build tools are in place, you can run the build:
$ meson build
$ ninja -C build
Run the tests using the following commands:
$ meson build
$ ninja -C build
$ ./build/signal_test
