让 Emacs `spacemacs` 接受根据 orgmode header 更改 latex 编译器的函数

Question

我在 emacs 25.3 上使用了最新的主版本 0.200。10.x Spacemacs。我正在尝试实现 orgmode documentation 推荐的功能，以允许用户定义 he/she 想要使用的 Latex 编译器。我实现了这个功能，但它似乎没有用。 Latex 编译步骤继续使用 pdflatex 而不是文件 header 中指定的 xelatex。所以我想弄清楚要做什么调整。

;; Originally taken from Bruno Tavernier: http://thread.gmane.org/gmane.emacs.orgmode/31150/focus=31432
;; but adapted to use latexmk 4.20 or higher.
(defun my-auto-tex-cmd ()
  "When exporting from .org with latex, automatically run latex,
     pdflatex, or xelatex as appropriate, using latexmk."
  (let ((texcmd)))
  ;; default command: oldstyle latex via dvi
  (setq texcmd "latexmk -dvi -pdfps -quiet %f")
  ;; pdflatex -> .pdf
  (if (string-match "LATEX_CMD: pdflatex" (buffer-string))
      (setq texcmd "latexmk -pdf -quiet %f"))
  ;; xelatex -> .pdf
  (if (string-match "LATEX_CMD: xelatex" (buffer-string))
      (setq texcmd "latexmk -pdflatex=xelatex -pdf -quiet %f"))
  ;; LaTeX compilation command
  (setq org-latex-to-pdf-process (list texcmd)))

(add-hook 'org-export-latex-after-initial-vars-hook 'my-auto-tex-cmd)

根据 Spacemacs 问题 list I need to make a change in the spacemacs-configuration-layers setting a la:

dotspacemacs-configuration-layers '(
  (latex :variables latex-build-command "LaTeX"))

问题是，在 dotspacemacs-configuration-layers 中进行更改似乎无法让我应用基于文件特定设置的更改。

有谁知道在 spacemacs 中实现上述功能的正确方法 (my-auto-tex-cmd)？

我在博客中找到了解决方案 post .

实际的elisp代码是：

;; Default packages included in every tex file, pdflatex or xelatex
(setq org-latex-packages-alist
      '(("" "graphicx" t)
        ("" "longtable" nil)
        ("" "float" nil)))
