Well, APDA won't answer technical questions, maybe someone inside apple who is reading this list can... CLOS and version 18 of Kent Pitmans condition system were accepted last summer by X3J13... when will ACL support them? Does ACL support logical pathnames? If not why not? What is the position on the emerging CLIM standard? How compatible is the existing window system with it? Will they support it if it is adopted?

Don't know about the last--you can deal with windows in ACL in two ways. The normal way is to use the built-in window handling code, which is based on Object Lisp (*not* CLOS), and works fairly well. However, you also have complete "raw" toolbox access, so it shouldn't be too bad to port Common Windows or CLIM to ACL. -- Amanda Walker InterCon Systems Corporation -- amanda@intercon.uu.net | ...!uunet!intercon!amanda

From: miller@CS.ROCHESTER.EDU (Brad Miller) Newsgroups: comp.sys.mac.programmer Date: 17 Aug 89 15:58:58 GMT Organization: University of Rochester Computer Science Department Well, APDA won't answer technical questions, maybe someone inside apple who is reading this list can... were you suprised? CLOS and version 18 of Kent Pitmans condition system were accepted last summer by X3J13... when will ACL support them? in version 2.0, which is currently under development. The next release is version 1.3, which is slated for October. 1.3's main new feature is a spiffy interactive interface editor (extensible for new classes of interface components, and comes with sources). Also some random other speed improvements and such. 2.0 is a much more ambitious rewrite, slated for not "some time in 90". Does ACL support logical pathnames? If not why not? MACL (the current name of ACL) has logical pathnames (has always had them). There are some differences with the recently adopted standard logical pathnames. We'll implement the new standard with 2.0. What is the position on the emerging CLIM standard? How compatible is the existing window system with it? Will they support it if it is adopted? We're aware of CLIM, and we're looking into it. Right now the spec is still being worked out, so it's perhaps too early to tell whether it will be as good as everyone hopes. We know that a portable window system is something everyone wants, and we want to keep our customors happy. . . I think it's pretty unlikely that CLIM would get adopted as part of the Common Lisp standard. If it does, then we wouldn't have much choice about supporting it (we're committed to supporting the full CL standard). The current window system was written without CLIM in mind, so I don't think there's much chance of them being 'compatible'. Do you mean "how easy would it be to implement CLIM on top of the current window system?" I really don't know. Parts would probably be easy, but other parts would also probably be very hard. -andrew disclaimer: The opinions expressed are mine only.

You can get PCL from arisia.xerox.com via anonymous ftp. It works under ACL, Symbolics, TI and many others. One grad here is using it with ACL and a MacII with satisfactory results. There may be other sources as well. -- Stephen M.
