Hiding ^M in emacs

Question

Sometimes I need to read log files that have ^M (control-M) in the line endings. I can do a global replace to get rid of them, but then something more is logged to the log

Like binOr said add this to your %APPDATA%.emacs.d\init.el on windows or where ever is your config.

;; Windows EOL
(defun hide-dos-eol ()
  "Hide ^M in files containing mixed UNIX and DOS line endings."
  (interactive)
  (setq buffer-display-table (make-display-table))
  (aset buffer-display-table ?\^M []))

(defun show-dos-eol ()
  "Show ^M in files containing mixed UNIX and DOS line endings."
  (interactive)
  (setq buffer-display-table (make-display-table))
  (aset buffer-display-table ?\^M ?\^M))

(add-hook 'text-mode-hook 'hide-dos-eol)
