 Minor glitch in dired listing due to non English host language
Date: Tue, 21 Jun 2016 10:31:59 +0200

When I enter in a `dired` mode, I see something like the following at the top
of the buffer:

  /home/lele/something:
  total used in directorye 8 available 24407396
  drwxrwxr-x 2 lele lele 4096 giu 21 10:02 .
  drwxr-xr-x 5 lele lele 4096 giu 21 10:02 ..

Note the “directorye” glitch: I think it is caused by the fact that the
function `insert-directory` in lisp/files.el assumes the underlying `ls`
command operates in an English environment, in particular in the first line
where it emits with the disk space usage, and perform a simple replace of
"total" with "total used in directory".

This is what I get with a plain `ls -la`:

  $ ls -la
  totale 8
  drwxrwxr-x 2 lele lele 4096 giu 21 10:02 .
  drwxr-xr-x 5 lele lele 4096 giu 21 10:02 ..

while it assumes an output like:

  $ LANG=en ls -la
  total 8
  drwxrwxr-x 2 lele lele 4096 Jun 21 10:02 .
  drwxr-xr-x 5 lele lele 4096 Jun 21 10:02 ..

Given that the function unconditionally inserts an English phrase, the
easiest-but-consistent workaround could be explicitly executing `ls` with
`$LANG` set to "en".

A more elaborated approach could be extracting only the number in the first
line of the `ls` output instead of matching "total": in this way it would
support also languages that swap the order (that is, that translate that line
to something equivalent “8 bytes in total”).

Thank you,
ciao, lele.

(This bug report unfortunately got no response at the time.)

This bug is still present.  Steps to reproduce:

LANGUAGE=it_IT.UTF-8 emacs -Q .

(You need to have an Italian locale installed.)

There's been a bit of discussion over the years about that summary line
in Dired, but I'm not sure whether anybody came to any conclusions.  I
guess we do not want to run "ls" under the C locale?  That would make
all the lines be in English, including the dates...

IMHO, it should be simply removed, it carries so little information,
especially nowadays.

ciao, lele.

I think we should delete everything except the number at the end.

I disagree.
Of course, it could be made optional.

And the argument that it carries little info isn't
an argument for showing no info.  It's an argument
for showing more or better info.
___

And yes, the info can be improved.

In my case (Dired+, files+.el), it shows this, for
any listing:

 z:/path/to/some/subdir:
 files 157/1659 space used 34111 available 101612836

`files 157/1659' shows the # of files currently
shown (visible) in the current subdir listing (157),
compared to the # of files in the main dir (1659).

And that `files 157/1659' is a link/button.
Mouseover tells you:

 Files shown / total in directory [RET, mouse-1: more info]

And clicking or RET shows you complete info about
that subdir.  E.g.:

z:/path/to/some/subdir
----------------------

File Type:                  Directory
Permissions:                drwxrwxrwx
Time of last access:        Wed Jul 25 08:26:24 2018 (Pacific Daylight Time)
Time of last modification:  Wed Jul 25 08:26:24 2018 (Pacific Daylight Time)
Time of last status change: Wed Jul 25 08:26:16 2018 (Pacific Daylight Time)
Number of links:            1
User ID (UID):              37686
Group ID (GID):             513
Inode:                      281464976926869
Device number:              315264003

Similarly, "space used 34111 available 101612836" is
a link/button.  Mouseover tells you:

 Kbytes used in directory, Kbytes available on disk

And the same info (see above) is shown when you click
or use RET.
___

And let's not forget that when Dired details are
hidden (`('), the line isn't shown at all.  (IMO,
details should be hidden, not shown, by default.)

I do, too.  Well, I think the entire line should be removed, and the
"free disk" number displayed somewhere else.

I've now introduced a new user option, `dired-free-space' to control
this, and defaulting it to showing only the available space (in the
first line).
