Line Wrapping set to Word Wrap in Summary Buffer - how to permanently change to Truncate Long Lines?

Hi

For some reason which I do not understand, the Gnus instance is always
switching back to "Word Wrap" in the summary buffer. Previously it was
staying at "Truncate long lines".

If I open a new Gnus instance, it is set to "Word Wrap", but a new
instance of emacs (same emacs.el file, same customization) is not.

How can I bring back the previous behavior line truncating mode for all
GNUS buffer?

Thanks,

Rainer.

Try this:

    (set-default 'truncate-lines t)

All this does not work if one sets global-visual-line-mode to 1 in a
different buffer...

Found it, changed it to visual-line-mode and everything is working
again.

Thanks,

Rainer

No - I don't want it - I had it for a different buffer.

Interesting - have never thought about that. Will look into this.

Thanks,

... do you really want `visual-line-mode' in a Gnus
summary buffer?

Anyway, instead of using defaults, it can be sensible
to set up things like this on a per-mode basis.
Especially since you mention the `gnus-summary-mode'
in particular probably this is what you should do.

For example, here is what I do for the HTML and XML
modes - as you see I disable `visual-line-mode' for
each.

You can do the same (or enable it) with
`gnus-summary-mode-hook', if need be.

;; HTML
(defvar html-mode-map)
(defun html-mode-hook-f ()
  (enable-line-mode)
  (define-key html-mode-map "\C-ow" #'w3m-view)
  (auto-fill-mode   -1)
  (visual-line-mode -1) )
(add-hook 'html-mode-hook #'html-mode-hook-f)

;; XML
(defun nxml-mode-hook-f ()
  (visual-line-mode -1) )
(add-hook 'nxml-mode-hook #'nxml-mode-hook-f)
