Re: Turn off auto-indent

Arash,

Did you check that?

I did.  I opened a testemacs.tex and said C-h v "electric-indent-mode".  Here 
are the first few lines of the result.

electric-indent-mode is a variable defined in ‘electric.el’.
Its value is nil
Original value was t
Local in buffer testemacs.tex; global value is t

That result looks sensible to me if it means that for .tex files it is nil, 
while for others it is t, maybe?  This is part of my current .emacs:

;; Turn off auto indent in AUC TeX
;; https://tex.stackexchange.com/q/468047/339
;; and https://emacs.stackexchange.com/a/30148
(defun remove-electric-indent-mode ()
  (electric-indent-local-mode -1))

(add-hook 'LaTeX-mode-hook 'remove-electric-indent-mode)
(add-hook 'tex-mode-hook 'remove-electric-indent-mode)

I ran 'emacs -Q' from the command line entered these lines in the buffer

(defun remove-electric-indent-mode ()
  (electric-indent-local-mode -1))
(add-hook 'LaTeX-mode-hook 'remove-electric-indent-mode)

and clicked on Lisp-Interaction > Evaluate defun.  I got no errors.  I then 
opened a .tex file.  It had this, but with "test" immediately after 
\end{itemize}.  When I hit <Enter> I got the "test" indented.

xxxx

\begin{itemize}
\item
    \begin{itemize}
    \item
    \end{itemize}
    test


\end{itemize}

I put the the whole .emacs, below in case that is helpful, since it is only 41 
lines.  Other than that, I think I have a standard Ubuntu emacs setup.

Thank you,
Jim

I think your current setup with `remove-electric-indent-mode' in
`LaTeX-mode-hook' is OK.  Therefore I asked:

> With the setting above, what is the value of the variable

Did you check that?

I suspect the problem is somewhere else in your setup.  Maybe you want
to start with 'emacs -Q', eval this

(defun remove-electric-indent-mode ()
  (electric-indent-local-mode -1))
(add-hook 'LaTeX-mode-hook 'remove-electric-indent-mode)

and activate AUCTeX followed by opening a .tex file?  So the standard
debugging process, that should give you a clue.

P.S. Please keep the mailing-list in CC, thanks.

Best, Arash
