* GUI
|
|
|
|
These things should happen early, so that Emacs will look the way I
|
|
want it to as quickly as is possible.
|
|
|
|
** menu-bar-mode
|
|
|
|
Disable =menu-bar-mode= since I haven't used the menu bar much ever,
|
|
even when I first started using Emacs.
|
|
|
|
#+BEGIN_SRC emacs-lisp
|
|
(menu-bar-mode -1)
|
|
#+END_SRC
|
|
|
|
** scroll-bar-mode
|
|
|
|
Since Emacs gives a pretty good indication of where in the buffer
|
|
I'm working I really don't need to have the scroll bar visible.
|
|
|
|
#+BEGIN_SRC emacs-lisp
|
|
(scroll-bar-mode -1)
|
|
#+END_SRC
|
|
|
|
** tool-bar-mode
|
|
|
|
I've never used the tool bar much, so remove it.
|
|
|
|
#+BEGIN_SRC emacs-lisp
|
|
(tool-bar-mode -1)
|
|
#+END_SRC
|
|
|
|
* load-path
|
|
|
|
Before doing anything else I should make sure that both the
|
|
directories ~/usr/local/emacs/share/emacs/site-lisp~ and
|
|
~/usr/share/emacs/site-list~ are included in =load-path=, along with
|
|
their subdirectories, but only if they haven't already been added
|
|
and exist. Place them at the end of =load-path= so they don't mess up
|
|
package precedence.

more features.

|
|
|
|
Don't show it when ~eldoc~ is running, I almost assume that it is

whenever I'm working in a mode that supports it anyway. This should

|
only execute once ~eldoc~ has been loaded.
