Org-babel adds extra indentation on each edit with `o` or `O`

Description :octocat:

Org-babel adds extra indentation to code blocks unnecessarily.

Reproduction guide :beetle:

• Start Emacs
• Open an org file. Ensure that you have run (setq org-startup-indented t)
• Make a code block, e.g. #+BEGIN_SRC python ... #+END_SRC
• Write some code in that code block
• Press o in evil mode to "open" a new line below the current one and enter insert mode
• Notice that the whole code block has been indented two spaces, unnecessarily

Observed behaviour: :eyes: :broken_heart: Code blocks auto-indent on every o or O edit operation

Expected behaviour: :heart: :smile: Code block indentation wouldn't auto-indent; indentation would stay the same inside code blocks once editing begins.

Confirmed.

This is what I'm seeing in an org-mode buffer, when pressing o on the print line:

Before

* test
#+begin_src python
print("test")
#+end_src

After

* test
#+begin_src python
  print("test")

#+end_src

I'm also getting this message:

Can’t guess python-indent-offset, using defaults: 4

but it might be working as expected: https://stackoverflow.com/questions/18778894/emacs-24-3-python-cant-guess-python-indent-offset-using-defaults-4

I think org-src-preserve-indentation is the variable you want to set to not add this extra indentation. I put that in my dotspacemacs/user-config:

(setq org-src-preserve-indentation t)

In fact my personal full default settings are:

  ;; src block indentation / editing / syntax highlighting
  (setq org-src-fontify-natively t
        org-src-window-setup 'current-window ;; edit in current window
        org-src-strip-leading-and-trailing-blank-lines t
        org-src-preserve-indentation t ;; do not put two spaces on the left
        org-src-tab-acts-natively t)

[duianto]

Confirmed. yogsototh's suggestion works.

There's also a variable for setting the default indentation:

(setq org-edit-src-content-indentation 0)

[aengle1429]

Added both duianto and yogsototh to my spacemacs user config and the issue appears fixed for me too. Upvoted both as well. I'm no emacs expert though and can't confirm whether everyone will have the same success. Thanks all

You can try to disable `evil-auto-indent' in org-mode:

(add-hook 'org-mode-hook
          (lambda () (setq evil-auto-indent nil)))
