Maybe make dired and list-directory deal with wildcards in positions like
~/.config/chromium/Default/*/menkifleemblimdogmoihpfopnplikde/

Thank you for the report.
IMO, this is a nice thing to have.

It must be possible to extend the current code so that
dired might handle wildcards in the directory part.

Following is a crude patch as a proof of principle.  Not heavily
tested yet, but for simple cases seems to work.

Thank you for making dired as powerful as ls(1).
Though I did not test your patch, I hope it gets into emacs.

Hi Michael,

i'd like to provide Tramp support for this new Dired feature.
The implementation is fairly straight: just adds a function
'insert-directory-wildcard-in-dir-p' in files.el, and use it in
'insert-directory' and Dired.

To get Tramp support i've added a handler
'tramp-sh-handle-insert-directory-wildcard-in-dir-p'.
Is this procedure OK or i am doing something weird?

Best regards,
Tino

    Dired: Handle wildards in directory part
    
    Allow to Dired to handle calls like
    \(dired \"~/foo/*/*.el\"), that is, with wildcards withing
    the directory part of the file argument.
    * lisp/files.el (insert-directory-wildcard-in-dir-p): New predicate.
    (insert-directory)
    * lisp/dired.el(dired-internal-noselect)
    (dired-insert-directory): Use it.
    * /etc/NEWS: Announce it.
    * doc/emacs/dired.texi (Dired Enter): Update manual.

Thanks, but this doesn't seem to work with ls-lisp.el, so I guess it
relies on some features of the 'ls' command.  (ls-lisp.el does support
wildcards in the likes of "C-x d foo* RET".)  So if we are going to
accept this, either it should be made to work with ls-lisp.el
(preferred), or some kind of error message should be emitted in that
case, because presenting an empty Dired buffer is not very
user-friendly.

A few random comments on the code:

This is unrelated, right?

Any reason you only want to support '*'?  What about '?' or '[a-b]',
for example?

Also, what happens if the directory includes a literal '*' character?
That's possible on Posix systems.

A typo.

That's not sufficient, it takes much more for adding a new handler in
Tramp. At least, it must be declared in tramp.el, and it must also be
added to the other backends but tramp-sh.el. 

And you can also not call it directly; Tramp is backwards compatible
with Emacs 24 and 25.

Unfortunately, there's no docstring, so it isn't clear to me what you
expect as result. Reading `tramp-sh-handle-insert-directory-wildcard-in-dir-p',
I believe you just want to work over the local part of a remote file
name. So you could do at the beginning:

  ;; DIR could be remote.
  (setq dir (file-local-name dir))

And I don't believe that it is mandatory to call
`insert-directory-wildcard-in-dir-p' in Tramp. All what's needed could be
done outside Tramp file name handlers.

Added support for (all?) posix globing.

Fixed.  Then, we will visit that file if does exist.


I have something working pretty well.  I gave up with `find-lisp' lib
because it was really slow.  I changed to use 'em-glob' which is really
fast!
But current implementation doesn't work with (Donald) tramp :-(.  If we
want this in tramp, i am afraid i will need a tramp super-expert,
i.e. Michael.

Best smiles,
Tino

I've applied your patch, and I've performed "C-x C-f
/scp:remotehost:~/src/tramp/*/*". It works as expected.

Neither "C-x d ~/src/*/lisp" nor "C-x d /scp:remotehost:~/src/*/lisp"
works. According to the NEWS entry in your patch, I would expect that at
least the former works.

Could you, pls, tell me what I shall do? Sorry, I didn't follow the
whole thread.

No, the former must fails because there is n match.  Maybe just the error is not clear.
The wildcard, ~/src/*/lisp
matches things like:
~/src/foo/lisp
but not:
~/src/lisp

I)
The following should match something:
C-x d ~/src/*/gray*

I got a dired buffer with 3 files:
bitmaps/gray1.xbm
bitmaps/gray3.xbm
bitmaps/gray.xbm

II)
If i try I) with tramp, for instance calling sudo:
/sudo:calancha <at> calancha-pc:/home/calancha/soft/emacs-master/src/*/gray* RET
then i get:

tramp-file-name-handler: Couldn’t ‘cd /home/calancha/soft/emacs-master/src/\*/’

;; Which doesn't sorprise me because my patch doesn't touch any

I should have said that there exist ~/src/emacs/lisp and
~/src/tramp/lisp. I would expect to see them with "C-x d ~/src/*/lisp".

I'll check again why it doesn't work for me.

When you are not using neither 'ls-lisp' nor 'eshell-ls', then it is the
system shell who performs the wildcard expansion.
That means, if the following doesn't work:
M-! ls ~/src/*/lisp RET
then,
C-x d ~/src/*/lisp RET
must fail as well.

That command works.

I'll check, what's up with your patch and why it doesn't work for me.

The second time I've applied your patch it works. I get a similar
result. Don't ask me what happened before, pilot error very likely.

Same error here. The backtrace shows me:

I believe it is wrong to expand wilcards in `insert-directory'. It is
not designed for that. Expanding must happen in
`dired-insert-directory', which calls then `insert-directory' for the
results.

This relates to your description in etc/NEWS:

*** Dired supports wildcards in the directory part of the file names.

Best regards, Michael.

Michael is giving me guidance wo i get we can get this working in tramp 
soon.

Hi Michael,

thank you for your advice on this.  I have a new version which handle the
expansion in `dired-insert-directory'.  I pushed a new branch with
the newest patch:
origin/feature/dired-wildcard-in-dir-bug#27631

When the user is neither using 'ls-lisp' nor 'eshell-ls', then we run 
in the remote host something like:
(process-file "/bin/sh" nil (current-buffer) nil "-c" (format "ls %s %s" switches wildcard)))

I have tested it running tramp in a remote machine and it seems to work.
What do you think?

Tino

I made a short test, works for remote directories. Likely, I'll add a
test to tramp-tests.el next days, in order to let it run for a variety
of other Tramp methods, like adb, gdrive and smb.

You might push it to master.

I'm not sure the recent patch for this fix is the right approach.
The old code already used the shell to do the wildcard expansion, so why
not just adjust the old code.

Here's some starting patch.

I'm not sure I understand what you mean by "used the shell to do the
wildcard expansion", but if you actually mean to let the shell do
that, it's unportable to non-Posix shells.

Just what you think it means: if you requested M-x dired RET ~/foo/* RET
it called "ls --dired -al *" from directory ~/foo.

My patch just changes the code so that M-x dired RET ~/foo/*/bar RET
is turned into "ls --dired -al */bar" from directory ~/foo.

I know.  That's why ls-lisp advises the corresponding function.

Thank you for the patch.
Part of the complexity of the original patch is to provide this new
feature in _tramp_ connections as well;  your patch does the thing
well (see patch below) in the local machine but it fails in remote 
ones.

I didn't adjust the Tramp code accordingly, indeed.  My patch probably
also fails for ls-lisp (aka Windows).  Both of those will need
corresponding adjustments.

My point is that it seems like we can get the same end-result without
changing the structure.

`n` represents a directory name, so isn't it OK to have "<n>/" rather
than "<n>"?  Or is the above tweak purely cosmetic?

Yes, my patch needs a bunch more cleanups: it was a quick hack job, just
to confirm my intuition.

Maybe that's the reason why this feature didn't exit before: people found
it wasn't straight to implemented it for everything: local and remote
connections, external  or emulated 'ls'.
Now we have it, but you are very welcome to rewrite it so that it fits in
the original structure.  I am volunteer to be the patch tester!
