Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
The doc string says "LOCALE-NAME should be a string which is the name of
a locale supported by the system." Isn't the set of locales supported
by the system something that Emacs can determine, and then make these
available as completion candidates? Why should a user have to
investigate or guess which locales are choosable?
It also says: "The locale names supported by your system can typically
be found in a directory named `/usr/share/locale' or `/usr/lib/locale'."
This does not help users who are not on a UNIX/Gnu/Linux platform.
Where can they be found on Windows, for instance?
Some of the code looks as if it is specific to UNIX/Gnu/Linux/X-Window.
Should the setting of `locale-translation-file-name' be specific to such
systems, for instance?
It also looks like the code for this command should be split
up/factored. Much of the command body is apparently about
non-interactive use (e.g. nil LOCALE-NAME) - factor that out, for
instance.

Nowhere a mere mortal can see it. The OS maintains the list of
supported locales, and will divulge it via a certain C-level API. But
you cannot find that list by searching files or directories, AFAIK.
As an interactive user, you can see the list in the Control Panel, but
programmatically the list is available only through that API.

Maybe, but I'm not sure a simple test for file's existence is worth
ugly system-dependent conditions. If nothing else, it allows Windows
users to have locale translations, something that could be considered
a feature.

Forgot to mention that this API has a Lisp binding in Emacs:
w32-get-valid-locale-ids. E.g., try
(mapcar 'w32-get-locale-info (w32-get-valid-locale-ids))

I think so, yes.

Because nobody provided a patch to provide the completion table.

Looking at `set-locale-environment', it already has a bunch of hacks
that depend on Unix-related stuff:
(setq locale-translation-file-name
(let ((files
'("/usr/share/X11/locale/locale.alias" ; e.g. X11R7
I wonder whether we should just add an equally hacky `get-locale-names'
function that would call that w32 function (if defined), and if not,
just parse the output of "locale -a" (if "locale" exists on the system).
Any opinions?

Before invoking 'locale -a', wouldn't it be better to use
locale-translation-file-name?
Otherwise sounds like a plan ;-)

The locale-translation-file-name file has all locales known, but what's
interesting is the list of locales available on the system, which is
what "locale -a" outputs.

Now implemented.
