Detect latexmk is running on currently buffer.

Detect latexmk is running on currently buffer.

[Hongyi Zhao]

Currently, I'm using the following configuration to automate the LaTeX
workflow in Emacs with AUCTeX:

```emacs-lisp
;; Automatically revert a buffer when the corresponding file on disk is updated.
(global-auto-revert-mode 1)
(setq auto-revert-use-notify nil)

;; Automatically save the buffer to disk periodically.
(use-package real-auto-save
   :hook ((TeX-mode python-mode) . real-auto-save-mode)
   :config
  (setq real-auto-save-interval 5) ;; in seconds
  )

;; After the buffer is changed and saved to disk, run latexmk on the
;; corresponding file immediately.
;;See ~/.latexmkrc for correspoding configuration
(use-package smart-compile
  :init
  (declare-function smart-compile-string "smart-compile")
  (defun run-latexmk ()
    (when (string-match ".tex$" (buffer-file-name))
      (let ((buf (get-buffer "*Background TeX proccess*")))
    (if (bufferp buf) (kill-buffer buf))) ;; flush previous log
      (start-process-shell-command
       "Background TeX" "*Background TeX proccess*"
       ;; use an external application as the previewer
       ;;(smart-compile-string "latexmk -pv %f")

       ;; use pdf-tools
       (smart-compile-string "latexmk %f")
       )))
  (define-minor-mode AutoTeX-mode
    "Mode for compiling latex sources and creating PDFs after saving."
    :global nil
    :lighter " Auto"
    (if AutoTeX-mode
    (add-hook 'after-save-hook 'run-latexmk t t)
      (remove-hook 'after-save-hook 'run-latexmk t)))

  :hook (LaTeX-mode . (lambda () (AutoTeX-mode 1)))
  )
```
Though the above method works, I meet a problem when the project LaTeX
files are large to some extent. To be more specific, when the project
is large to a certain extent, the compilation time of latexmk will be
relatively long, which may lead to the following race condition: When
the previous latexmk process has not ended, the subsequent latexmk
process is launched again.

Any hints for fixing this problem?

I use the "LaTeX mode defined in ‘tex-mode.el’" and there is
an important difference compared to yours, which is in line
with our respective styles, ha.

Anyway with LaTeX have a Makefile and just hammer it ... to
avoid getting institutionalized, don't ONLY do that, do
something else, light work (shell programming, even reading)
on the side, literally, and if/when you forget about LaTeX, do
force yourself to be reminded :)

I've seen calm guys punch into fences and stuff because that
constant recompilation can become a form of
self-torture, almost, soo frustrating. ha

Makefile example:
  https://dataswamp.org/~incal/borta/Makefile

Some helpers:
  https://dataswamp.org/~incal/emacs-init/latex.el

Bibtex:
  https://dataswamp.org/~incal/emacs-init/bibtex-incal.el
  https://dataswamp.org/~incal/emacs-init/bibtex/bibtex-next-volume.el

Very creative TeX, some would say :)

OMG, wonderful man with wonderful ideas and ELISP treasures!

It's called `latex-mode', as shown by `C-h o latex-mode RET':

latex-mode is an interactive native compiled Lisp function in
‘tex-mode.el’.

(latex-mode)

Well, let's not get carried away here ... but OK, thanks, I'll
take it to prevent the deadlock LOL :)

OK, so what is the difference between the other mode then?

1.1.3 Entering RefTeX Mode

To turn RefTeX Mode on and off in a particular buffer, use M-x
reftex-mode RET. To turn on RefTeX Mode for all LaTeX files, add the
following lines to your .emacs file:

(add-hook 'LaTeX-mode-hook 'turn-on-reftex)   ; with AUCTeX LaTeX mode
(add-hook 'latex-mode-hook 'turn-on-reftex)   ; with Emacs latex mode

Yeah, this exam is tough but no one said it was supposed to be
simple ...

Ah, I can't find the quote!

It is by S. Monnier anyway. Please tell him (the OP) if/as you
understand what I refer to ...

But I do remember, only I don't want to quote from memory
because my understanding of this is superficial ...

But, it has to do with LaTeX packages and how the different
modes handle that!
