some pathname wildcard code


Something like the following might be useful in implementing support
for wild pathnames in DIRECTORY in abcl.

One issue that I aware of but did not address is that I used
STRING-EQUAL in a couple of places that might be incorrect on Windows
and/or OSX.

  (:use :common-lisp :java))

(in-package :abcl-hacks)

(defun make-name-and-type-matcher (pathname)
  (let ((name1 (pathname-name pathname))
        (type1 (pathname-type pathname)))
    (flet ((to-string (jstring)
             (jcall (jmethod (jclass "java.lang.String") "toString") jstring))
           (split-path-and-type (s)
             (let ((dot-pos (position #\. s)))
               (if dot-pos
                   (values (subseq s 0 dot-pos) (subseq s (1+ dot-pos)))
                   (values s "")))))
      (cond ((and (eql :wild name1)
                  (eql :wild type1))
             (lambda (jstring) 
               (declare (ignore jstring))
               t))

Hi!

I'm about to step onto a flight, but let me take a minute to say
thanks for the contribution! When having a cursory look at
pathnames.lisp, I think to see some of the code that you wrote down
here too. I didn't look at your code long enough though to find out
whether it solves the "wild parents" problem: the fact that the path
we're looking at can't itself contain wildcard patterns (or at least,
that's the bug).

Bye,

Erik.

Re: some pathname wildcard code

speaking of pathnames - anyone run into the tendency of logical  
pathnames to lose their case?

Re: some pathname wildcard code

No, but I didn't use them very much yet. Do you have a reproduction
recipe? I'll gladly file a ticket if there's reason to.

Bye,

Erik.

Re: some pathname wildcard code

The code I wrote works ok at least for the case that I posted in my original report.
You could just give it a try!  I promise it will not erase your hard disk. ;-)

I did not intend to fully replace the code in pathnames.lisp, but rather to illustrate one approach
to a fuller fix.  I am not sure that I understand the overall structure of abcl to replace system
level code.
