C++ (Cpp) JSSTR Examples

Example #1

File: Error.c Project: pstef/flathead

js_val *
bootstrap_error()
{
  js_val *error = JSNFUNC(error_new, 1);
  js_val *prototype = JSOBJ();
  prototype->proto = fh->object_proto;

  // Error
  // -----

  // Properties
  DEF(error, "prototype", prototype);

  // Error.prototype
  // ---------------
  
  // Properties
  DEF(prototype, "constructor", JSNFUNC(error_new, 1));
  DEF(prototype, "name", JSSTR("Error"));
  DEF(prototype, "message", JSSTR(""));

  // Methods
  DEF(prototype, "toString", JSNFUNC(error_proto_to_string, 0));

  fh_attach_prototype(prototype, fh->function_proto);

Example #2

File: Error.c Project: pstef/flathead

// Error.prototype.toString()
js_val *
