Hi,
I'm looking for documentation on the __defineProperty__ SpiderMonkey
extension.

I'm looking for documentation on the __defineProperty__ SpiderMonkey
extension.

Do you mean __defineGetter__ and __defineSetter__?

Or in which version of Spidermonkey do you have a method
__defineProperty__ for what kind of object?

I saw it in Narcissus [
http://lxr.mozilla.org/mozilla/source/js/narcissus/js.js ] and figured
that it would therefore be in the current released Spidermonkey, but as
you point out it doesn't work on Spidermonkey as of Firefox 1.5. It
seems like the feature is only available in the HEAD-branch [
http://lxr.mozilla.org/mozilla/source/js/src/js.c ] where it's only
used in between #ifdef NARCISSUS, so it seems like an internal feature
making a metacircular interpreter a bit easier to write. The post would
have been more appropiate on netscape.public.mozilla.jseng.

Should be mozilla.dev.tech.js-engine any time soon as they have switched
servers already and are setting up a completely new newsgroup structure:

And right, asking there would probably give you an expert's (named
Brendan Eich) answer.
