[cdr-discuss] Extension packages (Re: file-local variables)

[Marco Antoniotti]

Hi

packages and extensions are a pet-peeve of mine. :)

I feel strongly on the subject and I have followed the following conventions in my recent coding (conventions which hinge on a non-standard and unadvertised feature of many implementations: see below).

Most of my packages are now named as

"IT.UNIMIB.DISCO.MA.XXX.YYY.ZZZ"

Then they may have nicknames, which can be

"COMMON-LISP.EXTENSIONS.DATA-AND-CONTROL-FLOW.STUFF" and "CL.EXT.DACF.STUFF" and "STUFF".

The naming scheme I adopted for the "COMMON-LISP.EXTENSIONS.CH" packages is that CH is the name of one of the ANSI chapters.  Of course, one could imagine a "COMMON-LISP.EXTENSIONS.NETWORKING" package and a "COMMON-LISP.EXTENSIONS.MULTIPROCESSING" package for things which do not appear in the ANSI.

I feel this satisfies my inner need for order.

Two notes:

The whole thing is predicated on an implementation raising an error (a PACKAGE-ERROR?) if two packages share nicknames; this is "mostly" the case.
The naming scheme is lengthy and - as it was pointed out in the past - kind of "polluting".

I still do think it is worth exploring... Note also that I am not suggesting a file system mapping for packages.

Having said so, this may be worth a CDR by its own.  Yet, maybe this is not the right venue for such discussion.

Cheers
