Is there a way to delete whitespace lines, but only at the end of
entries? (Such that you don't see blank lines when trees are folded.)

Org mode, of course. Here's an example:


    * Level 1
    Some text, two blank lines after


    some more text, two (or more) blank lines below!


    * Level 2
    Some other text

    blah blah blah

    * Level 3
    Some other text


When that's folded up, it looks like this:

    * Level 1

    * Level 2
    * Level 3

I'd like all instances of two or more trailing blank lines to be
condensed into one trailing blank line so I get a clean tree like
this:

    * Level 1
    * Level 2
    * Level 3

Check the variable `org-cycle-separator-lines`?

Status-Detective-783 · 2022-02-23 02:22

Yes, perfect!  I just set it higher:

     (setq org-cycle-separator-lines 5)

That's all I really wanted (even though I didn't know it, lol)!

You can perform a simple `query-replace-regexp` to remove all blank
lines but one before a heading:

```
\(^\s *
\)+\(^\s *
\*+\)
```
→
`\2`

But are you sure that what you want is not just increasing the value
of the variable `org-cycle-separator-lines`?

Yes, the latter is what I want, thanks!

Thanks for the regexp!  The regexp is what I asked for, but not really
what I wanted!  (It's also just a little dicey to run search/replace
regexp across an entire buffer... especially for a newbie like me.)

Btw, you can set it to 0 to avoid the guesswork.
The docstring of the `org-cycle-separator-lines` says:

    Special case: when 0, never leave empty lines in collapsed view.
