Hi,

I'd like project-files to work even if the project is located on a
remote system.  The patch attached is my attempt to achieve that.
This is my first contribution to Emacs, so any feedback is welcomed.

Thanks,
Felicián

Why that? `shell-command-to-string' works also on remote hosts.

That wasn't clear from the documentation and I haven't tried it out :(
Anyway, I've attached a new, simplified version.
However, now I wonder whether project--remote-file-name would be more
useful if it would derive the remote-id from default-directory.  Or
should I simply eliminate this helper function altogether?

Thanks,
Felicián

Yes, that's the usual approach.

Dunno, looks now like just a convenience function.

Looks good to me, except project--file-remote-name could do with a 
rename. At least call it ...-remote-nameS, maybe?

Or project--expand-remote-names.

Aside from that, '(concat remote-id file)' looks a bit iffy to me, but 
since you approved it, it must be fine.

It's according to the docs. remote-id is the result of a file-remote-p
call, which says in its docstring

--8<---------------cut here---------------start------------->8---
Tip: You can use this expansion of remote identifier components
     to derive a new remote file name from an existing one.  For
     example, if FILE is "/sudo::/path/to/file" then

       (concat (file-remote-p FILE) "/bin/sh")

     returns a remote file name for file "/bin/sh" that has the
     same remote identifier as FILE but expanded; a name such as
     "/sudo:root@myhost:/bin/sh".
--8<---------------cut here---------------end--------------->8---

Best regards, Michael.

I see.

If you like to push the patch yourself, please go ahead.

I don't know if it is still necessary, but I updated the patch with
renaming the defun in question by appending an "s" to its name.

Thanks,
Felicián
(ps. I've singed the copyright papers.)

I'm ready to commit it in your name. Reading the patch again, it might
be possible to simplify the code further.

concat accepts nil as argument. So the function could be rewritten:

(defun project--file-remote-names (local-files)
  "Return LOCAL-FILES as if they were on the system of `default-directory'."
  (let ((remote-id (file-remote-p default-directory)))
    (mapcar (lambda (file)
              (concat remote-id file))
            local-files))))

With this simple body, it might even not needed as function. We would
have then (untested)

  (let ((default-directory dir)
        (remote-id (file-remote-p dir)

...

    (mapcar (lambda (file) (concat remote-id file))
            (split-string (shell-command-to-string command) "\0" t))

WDYT? Do you want to prepare a patch along these lines?

Originally, I wanted to avoid this approach, because mapcar iterates
over the result even if remote-id is nil, but I guess the overhead is
negligible. I've attached the simplified patch.

Thanks,

That's how I read it too. I'm not so sure that the overhead is negligible.

Compare

(benchmark 1 '(all-completions "" obarray))

and

(benchmark 1 '(mapcar (lambda (s) (concat nil s)) (all-completions "" 
obarray)))

Sure, I'm aware of this difference. But there is (length obarray) => 15121
in my running Emacs stanza, and I doubt that so many files are handled
in project-files at once. And even if there are so many files, the other
operations on them will rule out this difference. So yes, I believe
this is negligible.

Best regards, Michael.

Thanks, I've pushed it to the master branch. Closing the bug.

Emacs contains ~4000 files.

Why not benchmark, then? I see a stable difference in project-files's 
runtime, on the order of 1-4%.

It's not a lot, but why create conses when we don't have to.

No problem from my side, change it as you believe it is appropriate.

Best regards, Michael.
