I put the following in my .emacs file:
(require 'dired-x)
(add-hook 'dired-load-hook '(lambda () (require 'dired-x)))
(setq dired-omit-files-p t)
(setq dired-omit-files
(concat dired-omit-files "\\|^\\..+$\\|-t\\.tex$\\|-t\\.pdf$"))
But C-x d
still shows me .pdf and .tex files. Did I get the syntax wrong in that last line?
Bonus question: Is there a way to get Dired to hide hidden directories, like .git folders?
A simple and very general solution which doesn't rely on any extras is to do C-u s
to change the ls
flags and immediately refresh (that is, C-u s
takes care of refreshing also, so there is very little typing involved). Usually you will want to remove -a
to hide dotfiles. But you can do everything you're already able to do in the shell console, which is far more than what a simple toggle mode could offer (at the cost of some extra keypressings). And there is a history of previous flags available, so "toggling" is pretty fast too.
Your regexp will match *-t.tex
files, not *.tex
ones.
With recent version of Emacs, it should be sufficient to add the following section to ~/.emacs
to filter what you want:
(require 'dired-x)
(setq-default dired-omit-files-p t) ; this is buffer-local variable
(setq dired-omit-files
(concat dired-omit-files "\\|^\\..+$\\|\\.pdf$\\|\\.tex$"))
Update: by default, dired-omit-files regexp filters out special directories .
and ..
. If you don't want this behavior, you can just override defaults (instead of inheriting them with concat):
(setq dired-omit-files "^\\.[^.]\\|\\.pdf$\\|\\.tex$")
The regexp ^\\.[^.]
will match any string of length 2+ starting with a dot where second character is any character except the dot itself. It's not perfect (will not match filenames like "..foo"), but should be ok most of the time.
