Re: 2.1.33 changelogs/cells

[Gabor Zoltan Csejtey]

Hi, in your mail:

http://www.octave.org/mailing-lists/octave-sources/2000/154

you wrote
...
NOTES: 

    copy OPERATORS/op-m-m.cc to OPERATORS/op-cell.cc before applying patch
    the patch will probably not apply without displacements since I did
    the changes on top of other patches I submitted recently.

Are those other patches incorporated into octave 2.1.33 or can you
give me a pointer to them or send the code?

I shall try your patch.

Thanks,

Gabor

        I clipped the cellget code from a more extensive (but still not 
complete)
        cell-array support patch that I posted last year to Octave sources:

                http://www.octave.org/mailing-lists/octave-sources/2000/154

        I'm not entirely certain that the function I define here will work 
without
        the rest of my patch but it probably will, and it is a quick way to get
        primitive cell support without building a patched version of Octave.  

        My patch does the sort of operations you would expect on cell arrays 
using
        (), but none of the operations which use {}.  Extening it will require 
changes
        to the parser to distinguish () from {}, changes to ov.h and ov-base.h
        to add the new type of dereferencing and changes to the parse tree to 
splice
        cell-dereferences into function arguments like all_va_args does 
presently,
        and to processing them intelligently when not in a function call.

        I'm hoping somebody ambitious will pick up my patch and extend it where
        needed, because I won't be doing so.  By the way, in my patch I overload
        the nth function for lists instead of calling it cellget.  Lists would
        also benefit from syntactic sugar for dereference.
