One of the common problems that ASDF users faced when introducing
the new binary location system is finding out where things reside.
Another problem we will eventually find is locating the resources
associated to an ASDF system which has been replaced by a
precompiled version.
In general it would be desirable for a system to be able to locate
its resources (additional files, icons, bitmaps, etc) using logical
pathnames.
if the "pure" system definition proposal finds adoption, then
something of this order will be necessary.
in which case, the option should support a full logical host mapping.
if purity is not an issue, a logical pathname value for the pathname
argument already allows for subsequent remapping, but that does
require that the host be defined in addition to the system.
if a non-root location suffices, it is also possible to support
remapping by placing logical roots in the registry list.
For that purpose I have coded a small patch that adds a new
keyword, :logical-host, to DEFSYSTEM. The keyword defines a logical
pathname translation from "**;*.*.*" to "path/to/asdf/or/pathname/
argument/**/*.*"
This way we may have
(defsystem :cl-unicode
:logical-host "cl-unicode"
...)
and in the sources load the databases such as "cl-unicode:uppercase-
table.dat"
