      Able to OPEN, PROBE-FILE, and LOAD contents of nested jar · ac72742b
      Mark authored
      Pathname.mergePathname() returns a Pathname, while Pathname.truename()
      returns a LispObject as it needs to be able to return NIL.
      PathnameURL.truename() coerces its result to a PathnameURL if necessary.

      ZipCache.Archive.getEntry() now works on pathnames relative to the
      root of the Archive.
      Able to retrieve the reference to the InputStream for a nested pathname.
      Now need to implement accessing entries within this reference.

      Fix Pathname.copyFrom() not to change order of DEVICE cons

      PROBE-FILE fails for archive stream
      Somewhere in the code we can construct root jar as a Pathname rather
      than PathnameURL which means that the two values are not
      java.lang.Object.equals(), so not matched.
      TODO figure out how we are getting such a value

      Delegate cloning of device to the JAR-PATHNAME Java object
      TODO PathnameXXX.createXXX() routines uniformly return object over
      LispObject.  Is this really necessary?  It seems to work now in a kind
      of "mixed" state.

      Make Pathname.init() static method · 71b6c1bc
      Mark authored
      Running under Netbeans, but failing to enumerate jar pathnames in the
      Java tests.
      Moved (most) Pathname.truename() invocations to using symbols
      Changed a lot of use of PROBE-FILE over TRUENAME.
      Running under Netbeans, but can't probe-file on jar locations:
        (probe-file "jar:file:/opt/local/share/java/abcl/abcl.jar!/org/armedbear/lisp/")
        (probe-file "jar:file:/opt/local/share/java/abcl/abcl.jar!/org/armedbear/lisp/boot.lisp")
      Loading from boot jar not working.
      Reading all the jar entries into the entry cache at once is not a good
      idea.  For abcl.jar this is ~10k entries which takes a noticable
      amount of time.
      And PathnameJar does not implement the right equals() contract, so
      looking up the entry in the cache doesn't work either.
      Running from abcl.jar!

      Good progress: able to load from abcl.jar.

      Mark authored
      Unfortunately, SLIME v2.26 code can throw errors when compiling Emacs
      buffers, namely the pathname may have a device containing the string
      "emacs-buffer" whose PATHNAME name denotes the buffer which often
      contain wild-pathname characters (e.g. "*slime-scratch*") causing a
      naieve PROBE-FILE to throw errors.
      TODO redo ABCL SLIME's use of PATHNAME-DEVICE components to mark a
      source location.
      Use IGNORE-ERRORS to be extra careful.

      (Daniel Kochmański)
      Cribbed from
      Simple MAPCAR must be replaced by a slightly more complicated DO, because the
      list may not be a proper list. I want to dedicate this ballad to myself.
          This is a tale of a sorry quest
          To master pure code at the T guru's behest
          I enrolled in a class that appealing did seem
          For it promised to teach fine things like T3 and Scheme
          The first day went fine; we learned of cells
          And symbols and lists and functions as well
          Lisp I had mastered and excited was I
          For to master T3 my hackstincts did cry
          I sailed through the first week with no problems at all
          And I even said "closure" instead of "function call"
          Then said the master that ready were we
          To start real hacking instead of simple theory
          Will you, said he, write me a function please
          That in lists would associate values with keys
          I went home and turned on my trusty Apollo
          And wrote a function whose definition follows:
              (cdr (assq key a-list))
          A one-liner I thought, fool that I was
          Just two simple calls without a COND clause
          But when I tried this function to run
          CDR didn't think that NIL was much fun
          So I tried again like the good King of yore
          And of code I easily generated some more:
              (cond ((assq key a-list) => cdr))
          It got longer but purer, and it wasn't too bad
          But then COND ran out and that was quite sad
          Well, that isn't hard to fix, I was told
          Just write some more code, my son, be bold
          Being young, not even a moment did I pause
          I stifled my instincts and added a clause
              (cond ((assq key a-list) => cdr)
                    (else nil))
          Sometimes this worked and sometimes it broke
          I debugged and prayed and even had a stroke
          Many a guru tried valiantly to help
          But undefined datums their efforts did squelch.
          I returneth once more to the great sage of T
          For no way out of the dilemma I could see
          He said it was easy -- more lines must I fill
          with code, for FALSE was no longer NIL.
              (let ((val (assq key a-list)))
                 (cond (val (cdr val))
                       (else nil)))
          You'd think by now I might be nearing the end
          Of my ballad which seems bad things to portend
          You'd think that we could all go home scot-free
          But COND eschewed VAL; it wanted #T
          So I went back to the master and appealed once again
          I said, pardon me, but now I'm really insane
          He said, no you're not really going out of your head
          Instead of just VAL, you must use NOT NULL instead
              (let ((val (assq key a-list)))
                 (cond ((not (null? val)) (cdr val))
                       (else nil)))
          My song is over and I'm going home to bed
          With this ineffable feeling that I've been misled
          And just in case my point you have missed
          Somehow I preferred (CDR (ASSQ KEY A-LIST))
                      -- Ashwin Ram,
