Strange autoindentation in org mode source blocks

Question

I try to use org-mode as a replacement for jupyter notebook, and I was faced with a problem: when I edit a python src block, newlines don't indent properly, so I have to press space 4 times after pressing RET.

I checked how the indentation works in elisp src blocks, it also works strange, see gif:

My org-mode config:

(use-package org
  :ensure nil
  :config
  ; (org-babel-jupyter-override-src-block "python")
  (add-hook 'org-babel-after-execute-hook 'org-redisplay-inline-images)
  (add-to-list 'org-structure-template-alist '("p" . "src python"))
  :custom
  (org-startup-indented t)
  (org-startup-with-inline-images t)
  (org-src-tab-acts-natively t)
  (org-src-preserve-indentation nil)
  (org-edit-src-content-indentation 4)
  (org-src-window-setup 'current-window)
  (org-babel-load-languages '((emacs-lisp . t) (python . t))))

(use-package org-superstar
  :hook (org-mode . (lambda () (org-superstar-mode 1))))

(use-package evil-org
  :after (org evil)
  :hook ((org-mode . evil-org-mode)
     (evil-org-mode . (lambda ()
                (evil-org-set-key-theme
                 '(navigation insert textobjects additional calendar))))))

Answer 1

Enter the block before editing it

To get proper indentation and other language features, you have to first enter the OrgSrc block with org-edit-special, which is by default bound to C-c '. See The Org Manual: Editing Source Code.

Also note you don’t have to type the #+begin_src and #+end_src manually, you can type <s then press TAB. See The Org Manual: Structure Templates.

Editing inline

If you want to be able to edit code blocks inline while having language features, you may want to look at this answer by malcook, which suggests it is possible with Polymode poly-org-mode. I haven’t tried this myself.
