Add a TeX symbol in the Emacs init file

2019-07-20 02:10发布

I am trying to add the following code to my .emacs init file:

(TeX-add-symbols '("eqref" TeX-arg-ref))

But I cannot get it to work. I get the following error when running emacs t.tex (t.tex is here a sample text file) from the command line:

Warning (initialization): An error occurred while loading `.emacs':
Symbol's function definition is void: TeX-add-symbols

I am using GNU Emacs version 23.3.1 on Ubuntu 12.04. My .emacs init file looks like

(setq TeX-auto-parse t)
(setq TeX-electric-escape t)
(setq reftex-label-alist '((nil ?e nil "~\\eqref{%s}" nil nil)))
(add-hook 'LaTeX-mode-hook 'turn-on-reftex)
(setq reftex-plug-into-AUCTeX t)
(TeX-add-symbols '("eqref" TeX-arg-ref))

If I enter ESC-: (i.e. running the command eval-expression) and enter (TeX-add-symbols '("eqref" TeX-arg-ref)) at the prompt it works fine. (That is after running this, I can enter \eqref in the buffer and it works as expected.. But this is not a good solution, having to enter this code manually each time I edit a file.. That is the reason why I try to set it up in the .emacs file..)

Background information for this question:

I have a problem with using the AucTeX style amsmath.el.. it seems that it is not loaded properly on my machine.. For more information, see Using \eqref with RefTeX.

You have to evaluate the code after LaTeX-mode is activated, otherwise you get the error Symbol's function definition is void: TeX-add-symbols. You can add that function to the hook of LaTeX-mode. In order to override possible other eqref macro definitions, you should add a dummy (ignore) to the definition of the macro. This code, in your .emacs, does the trick:

(add-hook 'LaTeX-mode-hook
      '(lambda ()
         (TeX-add-symbols '("eqref" TeX-arg-ref (ignore)))))
