Dear Developers, I found this annoying that if you got overlay.el loaded, the setnu.el will use overlay-api instead of XEmacs specific extents-api... And do cause a function defination void error. to reproduce: 1. (require 'overlay) 2. start setnu-mode in some buffer 3. insert a newline into the buffer 4. error BTW, Do you know why don't setnu.el use (featurep 'xemacs) instead of #'foundp some-extend-related-thing? A way to backward-compatible? Thanks, FKtPp ChangeLog addition: 2009-06-17 It's me FKtPp ;) <m_pupil(a)yahoo.com.cn&gt; * setnu.el (setnu-extent-at): re-order the #'cond -> #'foundp special form so that #'map-extents was detected first whether overlay.el loaded or not. edit-utils[Packages] source patch: Diff command: cvs -q diff -u Files affected: setnu.el =================================================================== RCS Index: setnu.el =================================================================== RCS file: /pack/xemacscvs/XEmacs/packages/xemacs-packages/edit-utils/setnu.el,v retrieving revision 1.3 diff -u -r1.3 setnu.el --- setnu.el 2002/07/24 18:36:50 1.3 +++ setnu.el 2009/06/16 16:49:32 ＠＠ -340,7 +340,15 ＠＠ (setnu-set-extent-property e 'evaporate nil) e )) -(cond ((fboundp 'overlays-in) ;; expect to see this in 19.30 +(cond ((fboundp 'map-extents) + (defun setnu-extent-at (pos buf) + "Finds the setnu extent at the position POS in the buffer BUF." + (map-extents (function (lambda (e maparg) + (if (setnu-extent-property e 'setnu) + e + nil))) + buf pos pos))) + ((fboundp 'overlays-in) ;; expect to see this in 19.30 (defun setnu-extent-at (pos buf) "Finds the setnu extent at the position POS in the buffer BUF."
