value of autofill changes when enabling this mode

[ppareit]

I've never used auto-fill (I prefer visual-line-mode), yet enabling this mode enabled auto-fill-mode for my latex buffer. This is unexpected.

The following emacs configuration fixed the issue for me:

(add-hook 'latex-extra-mode-hook 'turn-off-auto-fill)

That's odd. latex-extra doesn't contain a single reference to the `auto-fill-mode` variable. The only thing it does is change the function used for filling (but it doesn't actually turn on the mode). This could be some side-effect of your custom settings.

I had the same issue. @ppareit solution fixed it for me too.

The following worked for me (on v1.3, and I presume anything higher)

(setq latex/cleanup-do-fill nil)

Simply adding turn-off-auto-fill to latex-extra-mode-hook didn't fix things for me.

I think the problem is that auto-fill-function, which is the variable which holds the state for auto-fill-mode, is set by latex/auto-fill-function. Instead, a local value for normal-auto-fill-function should be set. That is for example what fortran-mode does. The following patch works for me:

  (defun latex/setup-auto-fill ()
    "Set the function used to fill a paragraph to `latex/auto-fill-function'."
    (interactive)
    (setq-local normal-auto-fill-function 'latex/auto-fill-function)
    (and auto-fill-function
         (setq auto-fill-function 'latex/auto-fill-function))))

The last two lines modify auto-fill-function in case it is alread set to another value, for example if auto-fill-mode has been turned on before latex-mode-extra.

I was experiencing the same issues (I don't use auto-fill and prefer virtual-auto-fill). The solution by @ppareit in #31 (comment) fixed it (the one by @iffsid in #31 (comment) did not). I am using latex-extra-20240909.2043 (and Emacs 30).
