Polylux - One Binary Multiple Languages

Polylux is a framework for building C++ extensions for common scripting languages, where a single binary can be loaded into different languages.

This software is purely experimental toy software and not suggested for any form of serious usage.

Example

Given an extension source like this:

#include "../src/entry/entry.h"
#include "../src/polylux.h"

#include <iostream>

namespace {
void hello() {
    std::cout << "hello ";
}

void world() {
    std::cout << "world\n";
}
}

static polylux::function_table_t<2> function_table{
    polylux::named_function{"hello", hello},
    polylux::named_function{"world", world}
};

POLYLUX_ENTRY(polylux_demo, "1.0.0", function_table)

And compiled like this:

clang++  --std=c++i17  -fvisibility=hidden -Wextra -g -ldl -fPIC   -o polylux_demo.so -shared src/entry/entry_php.cc src/entry/entry_python.cc  sample/sample.cc

The resulting binary can be called from Python:

$ python3 -c "import polylux_demo; print(polylux_demo); polylux_demo.hello(); polylux_demo.world();"                           
<module 'polylux_demo' from '/home/johannes/src/polylux/polylux_demo.so'>
hello world

Or from PHP:

$ php -n -d extension_dir=. -d extension=./polylux_demo.so -r 'echo new ReflectionExtension("polylux_demo"); hello(); world();'                                    
Extension [ <persistent> extension #15 polylux_demo version 1.0.0 ] {  - Functions {
    Function [ <internal:polylux_demo> function hello ] {
    }
    Function [ <internal:polylux_demo> function world ] {
    }
  }
}
hello world

What is missing?

Everything!
Handling of function arguments and return values
a build system
handlign of common APIs
really everything I didn'T implelement in a Sunday hacking session

About the name

Naming is hard ... polylux as word came to my head somehow. Much light, depending which runtime shines on it.
