Dired without ls?

Dired without ls?

[Deniz Dogan]

I've used Emacs on Windows for years now and only recently have I been
unable to use dired. I get the error that ls is not found.

Did I dream that ls is not required for dired? I'm almost 100 percent
sure I've used dired on Windows and I've never had ls installed.

No, you didn't dream.  Dired on Windows uses the Lisp emulation of ls,
in ls-lisp.el.

What does "C-h f insert-directory RET" say regarding where the
function is defined?  It should say that it's defined on ls-lisp.el,
if you are on Windows.

insert-directory is a compiled Lisp function in `ls-lisp.el'.

I tried with -Q and everything and couldn't get it to work. I filed a
bug report on it, but later found that it has already been reported in
#7869. Somebody should probably merge those two once my report comes
in.

Merge, and then close, because I just fixed it ;-)

Will do.  Thanks for reporting this bug, it looks like it's been there
for at least a month.

Is that in the development version of Emacs 24?  If so, I see that as
well, now.  Will investigate.

`ls' is not required for Dired on Windows.
On Windows, Dired uses `ls-lisp.el'.

Did you try with `emacs -Q'?  If so, and you see a problem, then please use `M-x
send-emacs-bug-report'.  If it works with `emacs -Q' but not otherwise, then
binary-search your init file to see where the problem lies.

There was a bug in dired.el on the development trunk.  I think I fixed
it, so please try again with the latest repository.

Indeed, it's not required.  The ls-lisp.el package included in Emacs
provides the necessary functions to let Dired works without ls.
AFAIK, this is used by default when running on Windows, tho it's
controlled by ls-lisp-use-insert-directory-program.
