This "wiping" is strange. `LaTeX-preview-setup' removes itself from `LaTeX-mode-hook' and adds `preview-mode-setup' instead. However, this should not affect other functions which also happen to be added to `LaTeX-mode-hook'. I just tried with emacs 24.5 and ELPA AUCTeX 11.88.6. My emacs just contained (add-hook 'LaTeX-mode-hook (lambda () :test)) After emacs startup, the value of `LaTeX-mode-hook' was (LaTeX-preview-setup (lambda nil :test)) And after opening some tex file, the value was (preview-mode-setup (lambda nil :test)) So that's expected, and my test lambda didn't get wiped out. > If I change > > '(LaTeX-mode-hook '(flyspell-mode LaTeX-math-mode turn-on-reftex)) > > within (custom-set-variables.. in my init file to > > '(LaTeX-mode-hook '(flyspell-mode LaTeX-math-mode turn-on-reftex) t) > > the customized value is not wiped. Hm, the second version says that your customs should be set right NOW and also made the default value of `LaTeX-mode-hook'. The former will apply the customization at some future point in time, I think after the (defcustom LaTeX-mode-hook ...) form has been evaluated when AUCTeX loads. I can reproduce the behavior you describe when I use customize instead of plain `add-hook' but I fail to see why your customizations are lost with the first entry above. My understanding is that your value should be set just when loading latex.el after evaling the corresponding defcustom form. That would be ok. AUCTeX itself just uses `add-hook' and `remove-hook' on `LaTeX-mode-hook', so your configs should persist. Anyone got a clue? Ok, here are some workarounds: 1. Use `add-hook' to add `flyspell-mode' and friends to `LaTeX-mode-hook'. 2. Put (package-initialize) *before* the `custom-set-variables' section. Then `LaTeX-mode-hook' is already defined when the `custom-set-variables' are applied which seems to fix the issue, too. 3. Use a t NOW argument for customizing `LaTeX-mode-hook' as you've found out yourself. Bye, Tassilo
