[Openmcl-devel] windows host definition

[Gary Byers]

If I understand correctly, you want to do (and -should- be able to do):

(setf (logical-pathname-translations "mac-home")
       '((#p"**;*.*" #p"v:/**/*.*")))

which is approximately equivalent to the first example in the dictionary
entry for LOGICAL-PATHNAME-TRANSLATIONS.

If I understand correctly and am not hallucinating, there's been a bug
in code called by TRANSLATE-LOGICAL-PATHNAME that prevents that from
working: a pathname such as "mac-home:file.lisp" will fail to match
the left-hand-side of that rule, because the missing host component in the
rule (which should be treated as :WILD) will fail to match the pathname's
host.

You unfortunately can't say:

(setf (logical-pathname-translations "mac-home")
       '((#p"mac-home:**;*.*" #p"v:/**/*.*")))

because the host part of the namestring in the LHS hasn't been defined
yet (see 19.3.1.1.1).

Luckily, you -can- forward-reference the host being defined by using
MAKE-PATHNAME, as in:

(setf (logical-pathname-translations "mac-home")
   `((,(make-pathname :host "mac-home"
                      :directory '(:absolute :wild-inferiors)
                      :name :wild
                      :type :wild
                      :version :wild)
      #p"v:/**/*.*")))
