[clisp-list] (make-pathname :directory (:absolute :wild))

[Pascal B. <pj...@in...>]

I cannot find anything in CLHS that prevents:

    (make-pathname :directory '(:absolute :wild))

(or any of its variants:
   =20
    (make-pathname :directory '(:relative :wild))
    (make-pathname :directory '(:absolute "a" :wild "b"))
    (make-pathname :directory '(:relative "a" :wild "b"))
)

but clisp does not accept it:

[pascal@thalassa pascal]$ clisp -q -norc

[1]> (make-pathname :directory '(:absolute :wild))

*** - MAKE-PATHNAME: illegal :DIRECTORY argument (:ABSOLUTE :WILD)
1. Break [2]>=20
[3]> (make-pathname :directory '(:relative :wild))

*** - MAKE-PATHNAME: illegal :DIRECTORY argument (:RELATIVE :WILD)

[5]> (make-pathname :directory '(:absolute "a" :wild "b"))

.35.225])"


Note that PATHNAME does not have that same reticence:

[14]> (pathname "/*/")
#P"/*/"
[15]> (pathname "/a/*/b/")
#P"/a/*/b/"
[16]> (pathname "a/*/b/")
#P"a/*/b/"
[17]> (pathname "*/")
#P"*/"
[18]>=20


MAKE-PATHNAME takes a "valid pathname directory":

    valid pathname directory n. a string, a list of strings, nil,
    :wild, :unspecific, or some other object defined by the
    implementation to be a valid directory component.
