Font lock is not reapplied when org-indent-mode is turned on about poly-org

[dustinlacewell]

Hmm, this issue is starting to drive me a little loopy.

Okay, further testing revealed:

Everything works fine even with org-indent-mode enabled, when I disable evil-mode. In fact fontification still works if I reenable evil-mode after loading the buffer with evil-mode disabled.

@srnnkls Did you continue using poly-org? I am not an evil user, so it's hard for me to test/devlop on it. I see no reason why evil-mode should interfere with font-lock though.

Hi, I have this issue while editing a large buffer (159KiB). But I cant reliably reproduce this behavior, often it occurs when I move outside of src block to the header of this block. I was trying to catch errors with toggle-debug-on-errors with no luck. If I kill the buffer after the fontification has gone with the point inside src block, and reopen it fontification won't work (point is inside src block). But if I leave the point outside of the src block, then fontification works as usual on reopening of the file.
I use org-indent-mode and evil-mode too.

Actually, I was able to reproduce it with this config and emacs 26.3.

(setq load-path
      (append '("path/to/polymode-20200411.915/"
 "path/to/poly-org-20200316.1315/")
              load-path))
(require 'poly-org)
(setq org-src-fontify-natively nil)
;;uncomment to reproduce
;;(setq org-startup-indented t)

and this org file:

* TEMP

#+BEGIN_SRC python
import math

#+END_SRC

When org-indent-mode is enabled (org-startup-indented is t), then fontification won't work (e.g. try to comment import math).

Same problem. I tried everything but can't figure what causes this behaviour. Does the same trick whatever language : I have an org file mixing emacs-lisp, python and R.

fyi: the issue is not caused by org-indent but org-src-fontify-natively being disabled.

the fix is: pr42

org-indent still breaks font-lock after applying this patch 😭
