I understand. So the idea is to: a. keep the introspective loader b. design some "package loader" for AS similar to Tcl [package require] For the b. this works even now. All you need to do is to say "package require XYZ" in some library script and this will do the right thing. Provided the extension is pure Tcl OR it is thread-safe. So we need not design anything new. Just install Tcl package and use it from NS as you would from Tcl shell. Well, almost... The exception is Xotcl (and perhaps some other extensions that I'm not aware of) that do tricks with namespace client-data and some other nitty-gritty Tcl internals that Tcl itself does not know how to "clone". The problem is how to "persuade" a generic introspective loader that attempts to clone the "xotcl" namespace not to do that? Or, how to tell it to introscpect something that it does not know about? It "knows" about packages, procs, variables etc (well-known Tcl "things") but it does not "know" about any other data structures provided by extensions. Now, speaking of Xotcl... The older versions of init.tcl script contained a hack for it. Being considered a hack, I just left it out, with the hope to ditch that altogether in favour of a ns_ictl trace or Trace (lazyloader) as I'm still convinced that those are better (faster, simpler, more generic). Now, that popular demand is gearing towards "keep the a." we must think of how to parametrize the introspective loader so it can be "told" what to do and what not to do in certain cases. Right? I believe this will eventually lead to the same result as Ttrace, as I already followed that path some time ago, but I will let all you bright people think that over. Perhaps there is an elegant way I'm not aware of ;-) Cheers, Zoran ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
