* General Emacs Tips
|
|
|
|
Tips might be the wrong word here, but the way I use Emacs has
|
|
resulted into looking at some things that others might not think of
|
|
or see.
|
|
|
|
** Emacs Init File
|
|
|
|
Your Emacs init file can be any of the following:
|
|
|
|
- ~$HOME/.emacs~
|
|
- ~$HOME/.emacs.el~
|
|
- ~$HOME/.emacs.d/init.el~
|
|
|
|
I personally use ~$HOME/.emacs.d/init.el~ because that way I can
|
|
keep *everything* Emacs related in a single directory
|
|
(~$HOME/.emacs.d~).
|
|
|
|
** Displaying time
|
|
|
|
I've seriously minimized the use of my window manager's task
|
|
bar. It only shows which tags there are, some important daemons'
|
|
status (running or not) and whether or not I have mail. This makes
|
|
it difficult to tell time when I need it. That why it's useful to
|
|
see what time it is in Emacs, since that is on 99.99% of the time
|
|
I'm behind my computer, and it's very easy:
|
|
|
|
#+BEGIN_SRC emacs-lisp
|
|
(display-time-mode t)
|
|
#+END_SRC
|
|
|
|
That is all. When you have that in your [[Emacs Init File]], you will
|
|
always have the time in your modeline.
|
|
|
|
** Automatically compile startup files
|
|
|
|
I know that for 99% of the things you might have in your having a
|
|
compiled init files won't make much of a difference, but still I
|
|
like having my init files compiled. This gets messy when you share
|
|
your init files across multiple PCs and the source files become
|
|
newer than the compiled ones.
|
|
|
|
To fix this I've put only a very little bit of code in my actual
|
|
[[Emacs Init File]]:
|
|
|
|
#+BEGIN_SRC emacs-lisp
|
|
(require 'bytecomp)
|
|
|
|
(defvar startup-files
|
|
(directory-files "~/.emacs.d/startup/" t "^[^.].*\\.el$")
|
|
"A list of the files that should be loaded during startup.")
|
|
|
|
(while startup-files
|
|
(let ((filename (car startup-files))
|
|
(byte-compile-warnings nil))
|
|
(if (not (eq (byte-recompile-file filename nil 0) nil))
|
|
(load (substring filename 0 -3))))
|
|
(setq startup-files (cdr startup-files)))
|
|
#+END_SRC
|
|
|
|
It gets all the files in the ~$HOME/.emacs.d/startup/~ directory
|
|
that end with ~.el~. It loops through all these files and compiles
|
|
them, and then loads them. I use ~byte-recompile-file~ instead of
|
|
~byte-recompile-directory~ because the directory one didn't work
|
|
quite right. It doesn't recompile anything if the source file is
|
|
still up to date, so it only slows down when you have a lot of new
|
|
files in the ~startup~ directory. It also disables warnings so
|
|
that you're not bothered by them during startup.
|
|
|
|
* Emacs as...
|
|
|
|
There are *many* things Emacs[fn:emacs] is useful for, not just
|
|
coding and writing, but certainly very much for these uses as well.
|
|
|
|
