UK date format in Dired

UK date format in Dired

[Graham Smith]

[-- Attachment #1.1: Type: text/plain, Size: 212 bytes --]

Is it possible to get Dired to show dates in UK format.  I have added a line
to .emacs to show the diary dates in European format, but cannot find any
instructions to change the format in Dired.

Thanks,

Graham

Should be possible, if you can talk ls into doing so.  Possibly just
setting the appropriate locale variable (LC_TIME) in the environment
will do the trick.

To use another ls than the first one in PATH, set the variable
insert-directory-program to its pathname.  And set the variable
dired-listing-switches to the command line switches you need (as a
single string; will be converted to a list by the shell).

Oh, if you're on windows this won't help, and neither can I.

Harald,

Thanks for the help, but yes I am on Windows, and all OS regional settings
are already set up for the UK.

Then what is the problem, exactly?  If your Windows regional settings
are already set up for the UK, Dired should automatically use the date
format you set up via the regional settings.  That's because, on
Windows, Dired uses ls emulation written in Lisp (see ls-lisp.el in
the Emacs distribution), which eventually calls Windows APIs to
display the date and time.  So it should ``just work'' as you expect.

Can you please show us the details of your regional settings (in
Control Panel), and an example of Dired display?

Also, what is your value of the variable
ls-lisp-use-insert-directory-program?

As you can see dates are year-month-day, rather than day-month-year

Screen shot of regionalisation settings is attached.

I'm not sure how to apply ls-lisp-use-insert-directory-program

If I try

M-x ls-lisp-use-insert-directory-program

I get [no match]

You might add a customisation like that

	'(dired-listing-switches "-alD --time-style=locale")

On UNIX is lists like:

Peter,

Thanks, be fine and I have added this line to my .emacs , but it has made no
difference.

Is the "locale" in the code the actual text or am I meant to replace with a
regional name eg "european"

I remember a time on MS DOS or MS Windows where a shell interpreter  
was available, command.com, in its own window (or terminal). Maybe  
you have a similiar thing by hand. It should work to invoke 'ls -- 
help' to see what the ls command understands. The GNU ls command I  
use in my Emacsen on Mac OS X tells me (usually in German, because I  
have the environment variable LANG set to some German value) that it  
accepts:

   -a, --all                  do not ignore entries starting with .
   -A, --almost-all           do not list implied . and ..
   -B, --ignore-backups       do not list implied entries ending with ~
   -D, --dired                generate output designed for Emacs'  
dired mode
   -h, --human-readable       with -l, print sizes in human readable  
format
                                (e.g., 1K 234M 2G)
       --si                   likewise, but use powers of 1000 not 1024
   -l                         use a long listing format
       --time-style=STYLE     with -l, show times using style STYLE:
                              full-iso, long-iso, iso, locale, +FORMAT.
                              FORMAT is interpreted like `date'; if  
FORMAT is
                              FORMAT1<newline>FORMAT2, FORMAT1  
applies to
                              non-recent files and FORMAT2 to recent  
files;
                              if STYLE is prefixed with `posix-', STYLE
                              takes effect only outside the POSIX locale

And I tried exactly

          '(dired-listing-switches "-alD --time-style=locale")

in an UK based environment and it worked. 'ls --version' returns for  
me as first line

	ls (GNU coreutils) 5.96


If you do not have GNU ls available, then GNU Emacs uses some ls  
emulation. This one cannot be switched to display the date in some  
'local' format.


I have one (actually two) more thing(s) set:

	(setq insert-directory-program "gls" dired-use-ls-dired t)

This tells GNU Emacs to use GNU ls instead of a built-in or system ls  
command:

	insert-directory-program is a variable defined in `files.el'.
	
	Documentation:
	Absolute or relative name of the `ls' program used by `insert- 
directory'.


	dired-use-ls-dired is a variable defined in `dired.el'.
	
	Documentation:
	Non-nil means Dired should use `ls --dired'.

Could be they are accessible via customisation ...

Pete,

I can't say I follow all of this, but I don't think I have GNU installed and
as I understand it, I need this for this line of code to work.

Thanks for your help, maybe I will just live with it.

This probably depends on whether your using the elisp version of ls or the ls
that is installed on your system (the one which would be called in a shell). 

If your using the elisp ls emulation, check out ls-lisp-format-time-list. I use
the ls-lisp function rather than the native ls program because I also like
dired to list directories first.

Tim,

Thanks for this, I don't know which version of ls I am using, but I am
running emacsW32, and maybe this has modified some aspect of this. I have
now asked across on its support forum about it.

The "setq" code suggested in the help doesn't make any difference :-(

Indeed, although its a bit confusing with recent files, I think I might just
stick with the ISO date format, and come back to this when I know more about
emacs.

Thanks again for your help.

This won't make any difference on the OP's platform, since the --time
switch is not supported by the ls-lisp.el emulation of ls.

Again, Emacs on the OP's platform doesn't use any external program to
produce the Dired listing, it uses the emulation in ls-lisp.el.  So
playing with `ls' switches will not help.

I know – I was referring to an installation of GNU ls. And only to  
this a locale would have an effect, too.

It turns out this is a feature of ls-lisp, the emulation of the ls
program used by Emacs on Windows.  Interested readers can read the
message I posted to help-emacs-windows with the detailed explanation
(look for the thread with the same Subject as this one).

should be tested first, especially since there's more than one port of
