This is a simple C++ callback library. It's conceptually similar to FastDelegate, Qt, and countless other "typesafe callbacks in C++" articles across the web.
This library was developed with a primary goal of having an extremely simple, clean API. Secondary goals include low memory (low template bloat), zero external dependencies, and a high level of portability.
Using the library is incredibly simple. First, add the files to your project, Makefile, IDE, etc. Then, to use the library, simply include "signal.h".
Here's a simple example:
#include "signal.h"
void beep() { /* make speaker beep */ }
void flash() { /* make screen flash */ }
int main(int arg, char** argv)
{
// create a signal which we'll emit any time a button is pressed
signal<void> button_pressed;
// connect (i.e. subscribe) functions to the signal
button_pressed.connect(&beep);
button_pressed.connect(&flash);
// main loop, check for button press, and call signal
while ( true )
{
if ( is_button_pressed() )
{
// call signal, which in turn calls all slot functionss (i.e. subscribers)
button_pressed();
}
}
}
- better documentation
- consistent code cleanup
- generate.rb creates a single header file
- add License clause to source and LICENSE file
