1) Running a standalone script with SpiderMonkey on Linux
js -f scriptfile.js scriptarg
How can I get the value of scriptarg from within the JavaScript
scriptfile?
2) Running a standalone script with SpiderMonkey on Linux
How can I do formated printing to stdout?
(I see that /js/src/perfect.js uses print() is there an equivalent for
printing formated reals?)

I am embedding Spidermonkey in a C app. and I'm having trouble setting
class (not instance) property values. For example, I am setting up
the class as follows:
static JSBool constructor(JSContext *cx, JSObject *obj, uintN argc, jsval
*argv, jsval *rval)
{
printf("constructor argc = %d
", argc);
*rval = OBJECT_TO_JSVAL(obj);
return JS_TRUE;
}
main()
{
....
static JSClass my_class = {
"MyClass", JSCLASS_HAS_PRIVATE,
JS_PropertyStub,JS_PropertyStub,JS_PropertyStub,JS _PropertyStub,
JS_EnumerateStub,JS_ResolveStub,JS_ConvertStub,JS_ FinalizeStub
};
static JSPropertySpec class_props[] = {
{"Prop1", 0, JSPROP_ENUMERATE},
{0}
};
JSObject *proto;
proto = JS_InitClass(cx, JS_GetGlobalObject(cx), 0, &my_class,
constructor, 1, NULL, NULL, class_props, NULL);
The above code correctly (verified through a JavaScript program). creates a new class with the Prop1 class property.
The following code correctly adds an _instance_ property:
jsval val = INT_TO_JSVAL(42);
JS_SetProperty(cx, proto, "MyProp2", &val);
After three days I still can't figure out how to set the value of the class
property, or, for that matter, create a new class property with a particular value. I am looking to do something like this:
jsval val = INT_TO_JSVAL(88);
JS_SetProperty(cx, ???, "Prop1", &val);

I want to make a capture window in
*standalone* (in a *.js file) javascript, much in the same way as the
VBscript inputbox() function. I can make it inside a *.html file with
the prompt() function.
Or, is there a way to make a window and then work with this window?

I've got some difficulties with my standalone SVG.here is my code:
<svg onload="init(evt)" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<script type="text/javascript" xlink:href="jquery.js"></script>
<script type="text/javascript" xlink:href="jquery.svg.js"></script>
[Code].....
When I load the SVG, I've got the "ping" but not the "pong"?!
I'm using jquery 1.6.2 with jquery SVG plugin 1.4.4
