Hello. The documentation (version 9.6) says:
2.2.3 Catching invisible edits ------------------------------ Sometimes you may inadvertently edit an invisible part of the buffer and be confused on what has been edited and how to undo the mistake. Setting ‘org-fold-catch-invisible-edits’ to non-‘nil’ helps preventing this. I visit a new file. I type * foo then <RET> then bar Then I move the cursor one line up and press <TAB> So now the headline is folded and I see * foo... In my understanding, 'bar' is now in an invisible part of the buffer. But whether org-fold-catch-invisible-edits is set to 'nil, 'error', 'show', 'show-and-error' or nothing (i.e., 'smart' by default in 9.6), if then I do M-x undo I visually see no change, but I can observe by unfolding the headline that 'bar' has disappeared. In my understanding of the documentation above and of the docstring for org-fold-catch-invisible-edits, this should only happen with 'nil'. What am I understanding incorrectly? Thank you. Tests performed with 'emacs -Q -l .emacs.git' with '.emacs.git' being (add-to-list 'load-path "~/Org/Coch-git/org-mode/lisp") (custom-set-variables '(org-fold-catch-invisible-edits 'nil) ;; or 'error or 'show or 'show-and-error (or nothing) ) giving: Org mode version 9.6.1 (release_9.6.1-239-g739ccf @ /home/cochard/Org/Coch-git/org-mode/lisp/) PS: a very minor incidental point: after 'bar' has disappeared, the headline is then void, so I tend to say that the ellipsis should immediately disappear as well. -- EOST (École et Observatoire des Sciences de la Terre) ITE (Institut Terre & Environnement) | alain.coch...@unistra.fr 5 rue René Descartes [bureau 110] | Phone: +33 (0)3 68 85 50 44 F-67084 Strasbourg Cedex, France | [ slot available for rent ]
