dired stands for DIRectory EDit. (Not sure how it’s pronounced.) It is very useful bundled application. When you do
C-x C-f then just hit enter. You’ll see something like
ls but with cursor on it. You can do a lot of stuff by this, but mainly, you’ll do open files, just choosing file with cursor, and hit enter. You can also delete by press d for marking. And then press x to execute it. I’m sure there’s a lot more to do, but that’s what I do so far.
If you’re a Mac person, and If you using Display ANSI colors on Terminal.app, and if you use black background theme, such as Pro, you hardly see color of Blue. You can try TerminalColoreopard. Yoshimasa Niwa made a SIBML extension for choosing ANSI color. This ANSI color setting can be only for for one user. Cannot be like theming, but I don’t change theme everyday, so that works fine for me.
In emacs, there are Major mode and Minor mode. Major mode work like a Perspective in Eclipse IDE. It gives certain kind of framework to work on a given issue. There are
js2.el. I use
js2.el for now.
In order to make
js2.el work, emacs needs to know which directory autoload search for. It’s like a path setting in your shell. How do you know which directories your emacs search for? Type
C-h v load-path. It will return your emacs’ search path. I found a nice article about load-path on emacs wiki. I wanna load everything in
~/.emacs.d is represented as follows.
(progn (cd "~") (normal-top-level-add-to-load-path '(".emacs.d")))
js2.el, put it into my
js2.el, then do
M-x byte-compile-file. You’ll get
js2.elc, which is pre-compiled version. Then add following lines in .emacs.el
;; js2-mode (autoload 'js2-mode "js2" nil t) (add-to-list 'auto-mode-alist '("\\.js$" . js2-mode))
now whenever you open *.js, you’ll use Js2 Major mode.
Tag is not like delicious tag. It’s more like search index.
I use exuberant ctags. Just compile and install (
./configure ;; make;; sudo make install). And disable original ctags (
sudo chmod a-x /usr/bin/ctags).
Outside of emacs, go to top directory of your source file. Try
You can do
M-x visit-tags-table and choose TAGS file first. But if you don’t choose TAGS file and try to do tag jump by
M-., you’ll be asked which file emacs should read anyway.
