org-freemind.el and rx

[Carsten Dominik]

Hi Lennart,

I am trying to keep org-mode also workable with XEmacs.  One problem  
here is that XEmacs does not have rx.  Would you object if I replace  
the rx macro calls with the string representations of the regular  
expressions in org-freemind.el?

Michael, an alternative would be to get rx ported to and included into  
XEmacs.  Is anything like this in the works, or would you like to look  
into this?


Cheers

- Carsten

I think the solution is to do rx (I sure hate textual regexps) - which
is on my list, but will likely be a while.

Here is an initial attempt at porting rx to xemacs:

Not fully tested so please test it.

I took a quick look, and it's failing byte-compilation because in
rx-any-condense-range:

(defun rx-any-condense-range (args)
  "Condense by side effect ARGS as range for Rx `any'."
  (let (str
	l)
    ;; set STR list of all strings
    ;; set L list of all ranges
    (mapc (lambda (e) (cond ((stringp e) (push e str))
			    ((numberp e) (push (cons e e) l))
			    (t (push e l))))
	  args)
    ;; condense overlapped ranges in L
    (let ((tail (setq l (sort l #'car-less-than-car)))
	  d)

'car-less-than-car is signalling 
  apply(debug error (wrong-type-argument listp ?\[))

l is (?\" ?\[) at this point, and I don't think you can call #'car on
either of those 2 elements. Either this code meant to use #'<, or the (t
(push e l)) is wrong, or we've discovered another difference between GNU
Emacs and XEmacs :)

Regards

Robert

Thanks for the port!!!

I tested it under Xemacs 21.4,

    -  good news it compiles fine, since delete-dups is now
       defined.


    -  bad news org-freemind does not compile when
    (require 'rx) is used, error message is attached. 

Looks serious maybe Mike can say something.

If you do, please keep the rx code as comments so we can get back to it later.

I've made some more changes to rx.el for xemacs compatibility.
Please try the new version: http://broadinstitute.org/~ilya/rx.el .

Also, org-freemind.el uses delete-trailing-whitespace, which is present
in Emacs but not in xemacs -- needs to be brought over.
