Duktape 1.x compatible print() and alert() bindings

The default print() and alert() built-ins were removed in Duktape 2.x because they depended on stdout/stderr and were thus a portability issue for some targets. This directory contains Duktape 1.x compatible optional print() and alert() bindings:

• Add duk_print_alert.c to list of C sources to compile.

• Ensure duk_print_alert.h is in the include path.

• Include the extra header in calling code and initialize the bindings:

  #include "duktape.h"
  #include "duk_print_alert.h"
  
  /* After initializing the Duktape heap or when creating a new
   * thread with a new global environment:
   */
  duk_print_alert_init(ctx, 0 /*flags*/);
  

  See duk_print_alert.h for available flags.

• After these steps, print() and alert() will be registered to the global object and are ready to use.
