When I start it as 'emacs -Q <file>.dtx‘ it opens the requested file in
DocTeX mode. 

Next I load 'outline-minor-mode‘.  If I than run the command
'outline-hide-body‘ I’d expect to be presented with the various
\section, \subsection, … commands.  But this does not happen. 

Instead the first meta comment, the documentclass command and the
document environment are displayed, see the text below.  Any other
sectioning command is hidden.

Thanks in advance.

I'd say this is by design: `latex-outline-regexp' defined in tex-mode.el
doesn't cater for headings which start with '%', but in doctex mode,
almost all of them do so.  So you have to tell doctex about it with this
piece of code (which I haven't tested) in your init file:

(add-hook 'doctex-mode-hook
          (lambda ()
            (setq-local latex-outline-regexp
                        (concat "[% \t]*" "\\\\"
                                (regexp-opt
                                 (append latex-metasection-list
		                         (mapcar #'car latex-section-alist))
                                 t))))
          (setq-local outline-regexp latex-outline-regexp))

Best, Arash

How do you insert \ref's?  I'm not sure if the stock doctex-mode
provides completion support for \ref-\label insertion.

Do you byte compile your init file?  Maybe wrapping the whole thing
inside

(with-eval-after-load "tex-mode"
  (...))

helps.

I agree.

Same applies to the \label comamnds, which won’t be found, when 
inserting \ref commands.

It looks promising, but did not fully do the trick. :-(

Emacs complains

I addd some DocTeX code into the document environment, like this:

% \iffalse meta-comment
% Real comment about the file and its purpose
% ...
% \fi
%\iffalse
%<driver>
\documentclass[…]{…}
\usepackage{…} % and other usual LaTeX preamble stuff

\CodelineIndex
\RecordChanges
\setcounter{IndexColumns}{2}

\begin{document}
 \DocInput{key-label.dtx}
% \sectio{…}
% \subsection{…}
\end{document}
%<driver>
%/fi

and it didn’t fold :-(

Sorry.

I think I had a typo in the code I suggested, it should read:

(with-eval-after-load "tex-mode"
  (add-hook 'doctex-mode-hook
            (lambda ()
              (setq-local latex-outline-regexp
                          (concat "[% \t]*" "\\\\"
                                  (regexp-opt
                                   (append latex-metasection-list
                                           (mapcar #'car latex-section-alist))
                                   t)))
	      (setq-local outline-regexp latex-outline-regexp))))

Now take a small example like this:

%\iffalse

\documentclass{ltxdox}
\usepackage{microtype} % and other usual LaTeX preamble stuff
\EnableCrossrefs
\CodelineIndex
\RecordChanges
\setcounter{IndexColumns}{2}

I see that I missed to say that the exact steps were:

  • Start Emacs with 'emacs -Q'
  • Paste this code into scratch buffer and eval it (it is the same code
    as in my last message)

     (with-eval-after-load "tex-mode"
       (add-hook 'doctex-mode-hook
                 (lambda ()
                   (setq-local latex-outline-regexp
                               (concat "[% \t]*" "\\\\"
                                       (regexp-opt
                                        (append latex-metasection-list
                                                (mapcar #'car latex-section-alist))
                                        t)))
                   (setq-local outline-regexp latex-outline-regexp))))

  • Open the .dtx file in my other message
  • Do 'M-x outline-minor-mode RET'
  • Do 'C-c @ C-t'

This is with Emacs30 (997a8dbc48).  If this doesn't work for you, I'm
out of ideas.

Best, Arash

Unfortunately, I get this result:

Add that lisp snippet to your init file and you should be fine.

You mean putting this in your init file still throws an error?

Your fix only works in a plain Emacsen, being started without 
any kind of init file. :-(

So, in principle, your fix works, but not, if I place it in my 
init file.

Bye

Dear Arash,

thank you very much for your ongoing support. :+1:

No, it does not throw an error, but it is not folding properly.

 1) Starting emacs -Q, 
 2) inserting the fix into *scratch* buffer,
 3) M-X eval-last-sexp ==> gives no error.
 4) Loading an DocTeX file, 
 5) M-x outline-minor-mode  ==> gives no error
 6) C-c @ C-t ==> presents all sectioning commands in the buffer

Very well.

But including it into my ~/.emacs file and 
  1) Starting emacs 
  2) Loading DocTeX file
  3) Choosing Hide-Body from the Oultine Menu or
     Typing C-c @ C-t on the keyboard

will only show \documentclass, \begin and \end{document} and 
nothing in between :-(

I am still running GNU Emacs 28.2 (build 1, 
x86_64-apple-darwin18.7.0, NS appkit-1671.60 Version 10.14.6 
(Build 18G95)) of 2022-09-12

Any hints?

Sincerely

   Jan

If the code works with 'emacs -Q' and not when in your init file, then
you have to bisect your init file.  My only guess is to check if you're
using AUCTeX instead of the built-in mode when you load your init file.

Best, Arash

Good Morning Arash,

I am sorry, but I only have a vague idea of what you mean with 
bisecting my input file.

I have tried to move your code up, so that it is the first 
code in my ~/.emacs file.  This didn’t change a thing.  Same
results as before.

(Same, if I make it the last code of my init file.)

What do you mean with „using AUCTeX instead of the built-in 
mode“?

What kind of check should I perform?

This are the essential lines of ~/.emacs:

;;; 
;;; AUCTeX (sometimes also called AUC-TeX) was developed at the
;;; Aalborg university in denmark.  It is a mighty mode to work with
;;; nearly any kind of TeX and LaTeX files.
(load "auctex.el" nil t t)
(require 'auctex-latexmk)
(auctex-latexmk-setup)

Therefore I guess, I am using AUCTeX?

Bye

  Jan

I mean that there are at least 2 major modes for editing LaTeX/docTeX
files.  One of them is the one built in Emacs provided by this file:

  http://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/textmodes/tex-mode.el

Another one is AUCTeX which you have to install yourself (since you're
on a mac, I assume you've installed yourself and pre-installed by a
distro).

> What kind of check should I perform?

I think the easiest way is to check the mode you're using with 'C-h m'.
If I open a .dtx file and hit 'C-h m', I see this because I'm using
AUCTeX:

  The major mode is docTeX/P mode defined in tex-mode.el:

  This function has :override advice: ‘TeX-doctex-mode’.

  This is an :override advice, which means that ‘doctex-mode’ isn’t
  run at all, and the documentation below may be irrelevant.
  [...]

When I start Emacs with the '-Q' switch, the same file reports:

  The major mode is DocTeX mode defined in tex-mode.el:

  Major mode to edit DocTeX files.

Because AUCTeX is not initialized and hence the built-in mode kicks in.

Yes, you are.  And if you have installed AUCTeX from ELPA (i.e. with M-x
list-packages), then you better drop the (load "auctex.el" nil t t)
line.

AUCTeX is a complete different beast w.r.t to outline-mode, so the code
I suggested cannot work when you use AUCTeX to edit a .dtx file.  I
suggest you close this report and open an AUCTeX feature request by
sending a message to bug-auctex <at> gnu.org.

Best, Arash

I see nearly the same as you do:

docTeX/FP mode defined in ‘tex-mode.el’:
Major mode to edit DocTeX files.

This function has :override advice: ‘TeX-doctex-mode’.

Same here.

> […] I suggest you close this report

OK.  Thank you very much for your support.

I’ll send a bug report to AUCTeX and this bug could be closed.

I still learned some lessons here. :-)

Bye
