Subject: Tramp and `dired-listing-switches'
Date: Thu, 07 Dec 2023 15:50:17 +0100 [thread overview]
Message-ID: <8734we5aom.fsf@dataswamp.org> (raw)
I'd like one setting for `dired-listing-switches' locally on
Debian and one remotely with Tramp, on an OpenBSD system.
If I use Tramp with the Debian setting (below), and list files
on the remote server I don't get any listing since the options
does not compute on what is another ls(1), not GNU ls but the BSD
(OpenBSD?) one.
[ OT: I never understood if all BSDs use the same toolchain or
if they have different tools as well, if anyone knows that? ]
Anyway, I wrote this to cycle between sets of
`dired-listing-switches' options. Optimally, it would be done
automatically so one don't have to strike the command.
Maybe one can use `tramp-bsd-unames' and
`tramp-check-remote-uname' to automate it.
Cycling the sets works, but I don't know if that method is the
cleanest way to do it. It uses a lexical let-closure and
`setf', `cdr' and `last' to make it circular.
Also, after cycling, how can I revert the the dired buffer?
`revert-buffer' doesn't seem to do it, nothing happens, but
cycling the option, then killing the buffer and revisiting
it, works. Files are displayed with the new set in play.
(setq dired-listing-switches
"-AGlX --group-directories-first -I \"*.meta\" -I \"#*#\" -I \"*.elc\"")
(let*((dired-ls-opts (list dired-listing-switches "-Al"))
(_ (setf (cdr (last dired-ls-opts)) dired-ls-opts)) )
(defun dired-ls-opts-cycle ()
(interactive)
(setq dired-listing-switches (pop dired-ls-opts)) )
(declare-function dired-ls-opts-cycle nil)
(defalias 'lc #'dired-ls-opts-cycle) )
