How can I override the org-mode indentation function of TAB in evil-insert-state-map? I'd like it to always fold and unfold the current or parent header, and switch the indentation functionality to another keybinding.

  • What is the output of C-h k while under evil-insert-state in org-mode? – TerryTsao May 19 at 5:17
  • org-cycle. Interesting... Why isn't the visibility cycling, then...? – ShadowRylander May 19 at 5:22
  • Found why. Please see below. – TerryTsao May 19 at 6:00

From the doc of org-cycle:

When point is not at the beginning of a headline, execute the global
binding for `TAB', which is re-indenting the line.  See the option
`org-cycle-emulate-tab' for details.

Seems setting org-cycle-emulate-tab to nil will do.


Relevant doc:

Where should ‘org-cycle’ emulate TAB.
nil         Never
white       Only in completely white lines
whitestart  Only at the beginning of lines, before the first non-white char
t           Everywhere except in headlines
exc-hl-bol  Everywhere except at the start of a headline
If TAB is used in a place where it does not emulate TAB, the current subtree
visibility is cycled.

Relevant code:

Note how when everything fails, fallback to cycle the headings (Last 4 lines).

(cond
       ......

       ((or (eq org-cycle-emulate-tab t)
        (and (memq org-cycle-emulate-tab '(white whitestart))
             (save-excursion (beginning-of-line 1) (looking-at "[ \t]*"))
             (or (and (eq org-cycle-emulate-tab 'white)
                  (= (match-end 0) (point-at-eol)))
             (and (eq org-cycle-emulate-tab 'whitestart)
                  (>= (match-end 0) pos)))))
        (call-interactively (global-key-binding (kbd "TAB"))))
       (t
        (save-excursion
          (org-back-to-heading)
          (org-cycle))))

  • Huh... Actually, in insert mode, it's still indenting the headers. Can I change that as well? – ShadowRylander May 19 at 6:28
  • @ShadowRylander That's weird. Setting nil works for me. I don't have doom emacs to dig further unfortunately. – TerryTsao May 19 at 6:40
  • Ah, fair enough; thank you kindly for the help either way! – ShadowRylander May 19 at 6:56
  • @ShadowRylander Actually, have you ever tried edebug? Source code of org-cycle isn't that long to track. Perhaps you can find which cond condition is the culprit. It's what I would do if I were to have this problem. – TerryTsao May 19 at 7:48
  • I was thinking more along the lines of attaching org-cycle to a keychord; if that tabs as well, I'll know for sure it's the org-cycle function itself. From there I could just use edebug, as you mentioned. – ShadowRylander May 19 at 11:55
