Re: Bug: org-cycle stops working on Org files with empty lines at end of buffer [9.4 (9.4-elpaplus @ /home/brentg/.emacs.d/elpa/org-plus-contrib-20200914/)]

[Nicholas Savage]

I can reproduce this. I'm on the most recent master with Emacs 28.0.50. Once the last line is deleted, org-cycle won't show the "**" line and the minibuffer continues to say "FOLDING" instead of cycling through the various states.

Hi,

Still loving Org mode!!  Keep up the good work.

Here is a bug, though:

Steps to reproduce:

Store the following into some .org file (in between the "cut-here" lines):

---cut-here---cut-here---cut-here---cut-here---cut-here---cut-here---

* TODO aaa bbb ccc

** TODO aaa bbb ccc

delete-this-line-to-see-the-problem

---cut-here---cut-here---cut-here---cut-here---cut-here---cut-here---

Move point at first asterisk (beginning of buffer).

Type TAB key (bound to org-cycle) multiple times and notice it cycles

the headings through the various levels of exposure.

Now go to the end of the buffer, and delete the one line there

containing "delete-this-line-to-see-the-problem", but retain the two

empty lines at the end.

Repeat the above steps with the TAB key at the top of the buffer, and

notice it stops working.

On the mailing list, I see some recent changes that might or might not

have broken this. I've not upgraded Org mode in a while:

Thanks!
