How to use

This extension has only several public functions:

• dux_initialize() : Initialize duktape-extension for specified Duktape context (duk_context)
• dux_tick() : Process tick routines for event loop
• dux_[p]eval_module_file[_noresult]() : Load file as a module and evalulate it
• dux_[p]eval_module_[l]string[_noresult]() : Load string (JavaScript) as a module and evaluate it

Example

#include <duktape.h>
#include <dukext.h>

int main()
{
    duk_context *ctx;

    // Create Duktape heap
    ctx = duk_create_heap_default();

    // Initialize duktape-extension without file accessor
    dux_initialize(ctx, NULL);

    // Load main source
    duk_eval_string_noresult(ctx, "setTimeout(function(){ console.log('hello world') }, 1000)");

    // Start event loop
    while (dux_tick(ctx)) {
        // dux_tick returns true if there are any incomplete jobs
        // You may insert some delays here to avoid busy loop
    }

    // Event loop finished
    duk_destroy_heap(ctx);

    // You don't need call any terminate function for duktape-extension.
    // All resources of duktape-extension will be destroyed in duk_destroy_heap()
    return 0;
}
