Interface tweaks

Some GUI optimizations

  (setq inhibit-x-resources t)     ; avoid problems with emacs daemon and cursor colors
  (set-face-attribute 'default nil :family "Mensch" :foundry "PfEd" :height 158)
  (setq inhibit-startup-message t) ; Eliminate FSF startup msg
  (setq frame-title-format "%b")   ; Put filename in titlebar
  (setq visible-bell t)            ; Flash instead of beep
  (set-scroll-bar-mode 'right)     ; Scrollbar placement
  (show-paren-mode t)              ; Blinking cursor shows matching parentheses
  (electric-pair-mode t)           ; electric-pair-mode on
  (setq column-number-mode t)      ; Show column number of current cursor location
  (mouse-wheel-mode t)             ; wheel-mouse support
  (setq fill-column 78)
  (setq auto-fill-mode t)                   ; Set line width to 78 columns...
  (setq-default indent-tabs-mode nil)       ; Insert spaces instead of tabs
  (setq-default tab-width 4)                ; set default tab 4 spaces
  (global-set-key "\r" 'newline-and-indent) ; turn autoindenting on
  ;(set-default 'truncate-lines t)          ; Truncate lines for all buffers
  (fset 'yes-or-no-p 'y-or-n-p)
  (setq sentence-end-double-space nil)
  ; delete trailing whitespace before saving
  (add-hook 'before-save-hook 'delete-trailing-whitespace)
  ;; Enable line numbers for some modes
  (dolist (mode '(;;text-mode-hook
                  prog-mode-hook
                  conf-mode-hook))
    (add-hook mode (lambda () (display-line-numbers-mode 1))))

  ;; Override some modes which derive from the above
  (dolist (mode '(org-mode-hook))
    (add-hook mode (lambda () (display-line-numbers-mode 0))))
