Setting truncate-lines to true for all .log files

Setting truncate-lines to true for all .log files

[Ones Self]

Hi,

I'd like to have all *.log files have truncate-lines set to t,
so lines will not wrap.  How would I set something
like that up?

When I open a .log file in emacs it goes into
fundamental mode.  I could set it to go to a differerent
mode using auto-mode-alist, but which mode?
Do I need to create a new mode for this?
Is there already a good mode dedicated to text
log files in emacs (I couldn't find one)?

Thanks for all your help

Text-mode? Sh-mode?

I never could decide which so I just customised

	'(truncate-lines nil)

Experience is what you get when you don't get what you want.

auto-mode-alist can contain any function, so you could get away with
this:

  (defun log-mode ()
    ;; You may want to call `fundamental-mode' or some other mode here
    (setq truncate-lines t))

  (add-to-list 'auto-mode-alist '("\\.log\\'" . log-mode))



If you want to make a proper mode:

  (define-derived-mode log-mode fundamental-mode "Log"
    ;; The mode runs `log-mode-hook', so you could use that instead.
    (setq truncate-lines t))

auto-mode-alist as above.
