Hi all,
can anyone give me a hint how to have my own modules
with LWW ?
I want to be able to (require 'foo) for some modules
in a way similar to CMUCL where (require 'foo) tries to find
the module in a predefined directory.
I know about mk:defsystem and ASDF but i assume that it
is still possible with native LWW.
Thanks in advance

Given that it already exists and is used, why not go ahead and support it?

Maybe I should try to make my simple little SMART-REQUIRE publicly available. -- (espen)

Note that logical pathnames can abstract the position of modules away. Even without the REQUIRE-MODULE I described just now, you can do: (require :com.cley.weld "CLEY-LIB:COM;CLEY;WELD;WELD-LOADER") (or whatever convention you want) which just leaves you to define the logical host appropriately. In fact to first order REQUIRE-MODULE just destructures the module name in the obvious backwards-domain-name way and then uses it to construct a sequence of appropriate (generally logical) pathnames. --tim

We have a structured version of REQUIRE, whereby you say something like: (require-module :com.cley.weld) And it will do some fairly smart (and configurable via a fairly hardy search spec) searching, looking for things like CLEY-LIB:COM;CLEY;WELD;WELD-LOADER and various other things. When it finds something it loads it and expects it to do a PROVIDE somewhere along the line (typically the loader file loads a sysdcl and then loads the system - there is actually some (hacky) support for `forgetting' system definitions). Apart from the forgetting-system stuff it it probably portable CL. I could make it available (but not now) if anyone is interested. Actually, it's possible that it *is* available if you look in my lisp hax stuff, I forget if that was part of the LW-specific things. --tim
MK:DEFSYSTEM as a standard entry point ADD-REGISTRY-LOCATION <pathname> which you can stick in your .lispwork init file. MK:LOAD-SYSTEM and MK:COMPILE-SYSTEM will look in the directories listed in MK:*CENTRAL-REGISTRY* for system definition files. That is to say, (mk:compile-system "foo") Will look for a file named "foo.system" in all the directories listed in MK:*CENTRAL-REGISTRY*. Hopefully, the file will contain a system definition form for system "foo". MK:*CENTRAL-REGISTRY* will always contain the current directory.

I'm not sure if this is what you're looking for but here are two old threads which might be helpful: <http://article.gmane.org/gmane.lisp.lispworks.general/495/> <http://article.gmane.org/gmane.lisp.lispworks.general/503/> Have a nice weekend, Edi.
