* GUI
|
||||
Disable the ~menu-bar-mode~, ~tool-bar-mode~ and ~scroll-bar-mode~ early on
|
||||
so the disappear quickly after emacs starts up.
|
||||
|
||||
These things should happen early, so that Emacs will look the way I
|
||||
want it to as quickly as is possible.
|
||||
#+BEGIN_SRC emacs-lisp

#+END_SRC
|
||||
|
||||
** menu-bar-mode
|
||||
Define a macro for deferring code until after emacs has started up.
|
||||
|
||||
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
|
||||
(defmacro eval-after-init (&rest body)
|
||||
"Defer execution of BODY until after Emacs init."

#+END_SRC
|
||||
Add ~/usr/share/emacs/site-lisp~ and
|
||||
~/usr/local/emacs/share/emacs/site-lisp~ and all their sub-directories
|
||||
to the ~load-path~ so I can use modules from both Emacs from the
|
||||
official repository *and* the self-compiled one.
|
||||
|
||||
** scroll-bar-mode
|
||||
This should be done both when compiling the elisp file and when
|
||||
loading it so it doesn't complain about missing modules and such.
|
||||
|
||||
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.

||||

|

(let ((default-directory dir))

|
||||
Defer loading my theme until after emacs initialization. This is
|
||||
because it has been installed with ~package.el~, and the packages aren't
|
||||
added to the ~load-path~ until _after_ ~init.el~ has been run through.
|
||||
|
||||
** tool-bar-mode
|

#+BEGIN_SRC emacs-lisp
|

(eval-after-init (load-theme 'yoshi t))
|
||||
#+END_SRC
|
||||
|
||||
I've never used the tool bar much, so remove it.
|
||||
Add some of my project directories and other important directories
|
||||
into ~load-path~ so I can easily load libraries in them. Also, if it
|
||||
exists, load ~loaddefs.el~ in each directory for autoloads.

* load-path
|
||||
Replace the question of ~yes~ or ~no~ with just ~y~ or ~n~, I have never (yet)
|
||||
accidentally typed a ~y~ or ~n~ when asked and typing ~yes~ or ~no~ is just
|
||||
too much work.
|
||||
|
||||
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.

|

Replace these functions with better alternatives. They offer the same
|
||||
functionality, plus more.
|
||||
|

Load my preferred theme after emacs has finished starting up. Use
|
||||
the ~emacs-startup-hook~ to wait until we're sure all ELPA packages
|
||||
have been loaded.

Add any other interesting paths to =load-path= and, if it exists,

load the ~loaddefs.el~ file from these directories.

* y-or-n-p
|

Don't ask ~yes~ or ~no~, ask ~y~ or ~n~, I've never had an accidental ~y~ so

far.

Use =ibuffer= instead of the default =list-buffers= because it has many

* eldoc
|
||||
|
||||
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.
