Find script URL

[bijumaillist]

On many JavaScript libraries one thing I noticed is the author trying
find the host/dir where the script is hosted, so that he can
dynamically add additional scripts as and when needed.

Do have something simple as navigator.scriptURL and
navigator.scriptLineNum to provide information of currently executing
script?

navigator.scriptLineNum to provide information of currently

As far as I know, there's no built-in object or method that does this
for you, since "document" and "window" don't exist outside of
browsers. But it's pretty easy to do it manually. Offhand, you could
do something like this (lacks error checking):

// Assumes:
JSContext* context = ...;
JSObject*   global   = ...;
const char* filename = "foo.js";

JS_DefineProperty(context, global,
    "filename", STRING_TO_JSVAL(JS_NewString(context, filename,
strlen(filename))),
    NULL, NULL, JSPROP_READONLY | JSPROP_PERMANENT));

Then, in your script, the property filename will be set to foo.js.

Hope that helps.
