I want to activate reftex-isearch-minor-mode and tried the solution in this post offered by giordano,

(add-hook 'TeX-mode-hook (lambda () (reftex-isearch-minor-mode))) ; for AUCTeX

it works when I first open .tex file on emacs, but the minor mode will be lost, and the multi-search mode becomes the usual search mode after either C-c C-n or revert buffer.

How can I keep the reftex-isearch-minor-mode when I do the refreshing? Many thanks!

My AUCTeX version is 11.90.2, emacs version is 24.5.2

  • What happens if you pass a positive argument to reftex-isearch-minor-mode? I.e., (add-hook 'TeX-mode-hook (lambda () (reftex-isearch-minor-mode 1))).

  • @ArashEsbati sadly, no... and now I cannot even get it to work after restart. Except when I do manually M-x reftex-isearch-minor-mode RET. I probably should not be asking this, but what is the minimum amount of code in the .emacs to make it work? I have tried this line alone, and with (setq TeX-parse-self t), and a lot other variants...

  • @ArashEsbati, I just found that (add-hook 'LaTeX-mode-hook (lambda () (reftex-isearch-minor-mode))) does work (with TeX-LaTeX), at least so far... but I have to put it before (add-hook 'LaTeX-mode-hook 'turn-on-reftex). Does this make sense?

Here is the way to go:

(defun mylatexhook nil
   (turn-on-reftex)
   (add-hook 'reftex-mode-hook 
      (lambda nil (reftex-isearch-minor-mode 1))))

(add-hook 'LaTeX-mode-hook 'mylatexhook)

It has to be done in two steps, that was the mystery to be solved!

HTH, O.

Hello some years afterwards,

For those who are still searching for an answer like me ... I decided to go for the radical line of code

(eval-after-load "reftex" (setq reftex-isearch-minor-mode t))

in my .emacs file.

reftex autoloads lots of things ... This way, we are sure that we overwrite the initial value (that is nil in reftex.el).
