[EIEIO] Using 'setf' on a slot accessor

  Hi

  In the past few months, I unfortunately can't work a lot with
EIEIO [1].  Today, I surprisingly found the following error while
trying to use 'setf' on a slot accessor function:

    ELISP> (defclass A () ((s :initarg :s :accessor get-s)))
    [defclass A nil nil
      ...]
    ELISP> (setf (get-s (A "name" :s 'value)) 'new-value)
    *** Eval error ***  Invalid slot name: "#<A name>", get-s
    ELISP> 

  I found nowhere if this is valid or not.  Is it?

  [1] Erik, did FSF say you I signed the copyright assignment?

It probably should be.  The setf macro is in eieio.el line 519, and I
don't really know how it works.

I have had no news of your assignment.  I've gotten email confirmation
about my own assignments, but no paper mail in return.  I was told by
rms to ask tedt <at> gnu.org to learn about if any such mail arrives, but
got actual email from copyright-clerk <at> fsf.org, which seems like a
better choice of email addresses.

Thanks
Eric

  Ok, thanks.  I didn't really look for.  I guess there is a typo.  See
the patch at the end of the email.

  I've receive an email for my assignments, too.  This email had a PDF
file attached, wich is a scan of the both-parties signatures.  If I
remember well, no paper will be send, until explicit demand.  I'll
forward you this PDF.

  Here is the patch:

[EIEIO] 'initialize-instance' SLOTS arg is a list of list

  Hi

  From (info "(eieio)Default Superclass"):

     - Function: initialize-instance obj &rest slots
         Initialize OBJ.  Sets slots of OBJ with SLOTS which is a
         list of name/value pairs.  These are actually just
         passed to `shared-initialize'.

  But this method effectively receive a list of list.  More
precisely a list of a single element, itself a property list of
slots names and values (I'm not sure its the same as "name/value
pairs", which sounds more like an alist to me):

    ELISP> (defclass A () ((a :initarg :a)))
    [defclass A nil nil ...]
    ELISP> (defmethod initialize-instance ((obj A) &rest slots)
             (message "Slots: %S" slots))
    initialize-instance
    ELISP> (make-instance 'A "name" :a 'a)
    [object A "name" unbound]
    ELISP> 

  In the echo area:

    Slots: ((:a a))

  The 'constructor' static method call 'initialize-instance' like
this:

Punkin Chunk

Hi all,

  I haven't been very communicative on this mailing list lately.  As
happens every year, I've been getting ready for the annual Punkin
Chunk.  That is now over, and you can read all about this years'
adventure at this URL:

Enjoy
Eric

semanticdb-default-save-directory

I have this in my .emacs:

 '(semanticdb-default-save-directory "$HOME/semantic")

added with a normal customize operation.
However, files do not appear there. 

How do I debug this?

  Mmh, what exactly appears in your ~/.emacs.el?  If it's exactly
what you show above, it's normal.  This creates a list, of two
elements, a symbol and a string, and then throw away this list.
Maybe you can make your ~/.emacs.el available on the web, at
least temporarily, in order to have a look at it.

  You can simply use this:

    (setq semanticdb-default-save-directory "~/semantic")

semantic-get-local-variables and wisent-java

Re: semantic-get-local-variables and wisent-java

Hi Suraj,

[...]

Oops you're right.  In fact I introduced that bug in my last change to
the grammar to handle the definitions of anonymous classes.  
I committed a fix to wisent-java.wy in CVS.

Copy the new version in your local cedet/semantic/wisent directory,
then, in that directory, run 'make wy' to recompile the grammar.

Thanks for your report.

Sincerely,
David
