Hi,

#+begin_src elisp :results output
(aaa
 bbb (
#x09#x09#x09ccc))
      ccc
#+end_src
looks like this in the editor
(aaa
 bbb (
        ccc))
          ccc

Line 1-3 were indented automatically by pressing Tab. In line 4 I inserted
6 spaces manually. This is what I would expect to find in line 3 too. But
at my surprise there are 3 tab chars in line 3. Line 2 was indented
automatically with 1 space.

1. So why is line 3 indented with 3 tabs instead of 6 spaces?
2. How can I prevent this?
3. Why does a tab have a width between 1 and 2 spaces?
4. How can I prevent this misalignment?

org-block face has fixed-pitch.

Org mode version 9.4.6 (9.4.6-gcf30f7
(setq-default tab-width 2)
(setq org-src-fontify-natively t
org-src-window-setup 'current-window
org-src-strip-leading-and-trailing-blank-lines t
org-src-preserve-indentation t
org-src-tab-acts-natively t)

Thanks,
Michael

Are you editing the source block using org-edit-special (C-c ,)? If not,
then you are not editing the source block with the correct syntax for
elisp and this will throw out auto formatting.

Your example block is invalid elisp code which is 
#+begin_src elisp :results output
  (aaa
   bbb (
        #x09#x09#x09ccc))
  ccc
#+end_src

but I don't see how you can get any output as it is not valid elisp. It
is not clear to me what you are trying to do. You have 3 tab characters
(#x09), so don't see why you would expect them to be spaces? 

If what you want is for hitting tab to insert only spaces, have a look
at the variable indent-tab-mode. You can, for example, do

(setq-default indent-tab-mode nil)

to force use of spaces instead of tabs. However, be careful about doing
this globally if you also want to contribute to projects where tabs are
used as this will cause havoc with diffs and git. You can also set this
on a per language (via mode hooks) or per project (via local variables).

To get a better feel for how language modes align code etc, you really
need to make sure the code you are trying to align is syntactically
valid and you are using the correct coding style for the language.

Hi Tim,

indent-tabs-mode was exactly what I was looking for.

Thank you,
Michael
