Subject: 26.0.50; Using local emacs+tramp with remote emacsclient
Date: Fri, 21 Apr 2017 18:15:25 +0200

[Message part 1 (text/plain, inline)]

My workstation is running a bleeding edge emacs full-screen in a
dedicated display.  When working on a server, from time to time I use
programs that invoke the shell EDITOR.  I can set EDITOR to emacsclient,
but that will just open emacs on the remote machine, which is not what I
want.  I want whatever editing job needs doing to pop up in my local
fullscreen emacs.

I can ssh to the server, so obviously I can use my local emacs to edit
files there via Tramp.  And server.el already has functionality for
listening on a TCP port, which is easily forwarded over ssh (there are
various hacks out there for forwarding unix domain sockets as well,
which I haven't tried).

The missing piece is simply a way to let emacsclient instruct emacs that
the files it passes to emacs are remote.  Attached is a patch for your
consideration which accomplishes this.

Additionally, it would be handy to have some tooling for conveniently
forwarding the correct ports and setting up EDITOR with the correct -T
option on the remote machine, but that is outside the scope of emacs
code, I think.

Thanks, I think this will be a welcome feature.  Please see a few
comments below.

server-use-tcp is not described in the manual, so I think we should
add its description somewhere, and then reference that place from this
text.

The value of EDITOR begins with a ", but ends with a ', which is
probably a mistake.

Why the test for argv[i] being an absolute file name?  And if relative
file names cannot be supported, I think emacsclient should emit an
error message rather than silently ignoring --tramp.

The shared file system is just the easiest way for emacs and emacsclient
to both see the same server file, containing port number and security
cookie.  The default placement of that file is in ~/.emacs.d/server, and
a shared /home makes sure it's reachable from both server and client.

I can see how that would be unclear.  I'll improve it, and fix the other
things you pointed out.

The previous hunk of the patch adds the tramp prefix to the -dir
argument, which ends up setting `default-directory' for the server
buffers.  That makes relative filenames work.

With an absolute filename, if we don't prepend the tramp prefix, the
`default-directory' is ignored serverside and emacs tries to open a
local-to-emacs absolute file.  So we need to prepend the tramp
formula to tell emacs that the absolute filename is remote.

It would probably do no harm to include the tramp prefix on non-absolute
filenames as well, but it's not necessary, due to the previous -dir.

I added a new node to the manual, "TCP Emacs server", and
collected/wrote documentation on the various related variables there.
Does this type of doc reorganization require its own NEWS entry?  I
didn't see the point, and so didn't write any.

As this is only tangentially related to the new feature, I made it into
a separate patch.  The updated feature patch applies on top of this
documentation patch, and references the new node.

I have hopefully clarified the wording and fixed the tagging and typos.
I noticed while writing the TCP server doc that Emacs was capitalized
elsewhere in the docs, so I updated the capitalization in the paragraphs
on the new option.

Jeez, writing good docs is hard.  Criticisms welcome.  :)

As I explained in my previous mail, both absolute and relative filenames
are supported.  There are no code changes in this updated patch set.

Thanks.

No.

I made minor changes in your wording, see the commit for details.

One thing I'd like you to try to remember for the future: any
additional nodes you add need to be added to the master menu in
emacs.texi, otherwise makeinfo might barf (did you run it?).

Thanks for your work, I pushed your changes to the master branch.

Thanks, I'll try to remember that next time.  (Sorry, I'm just
cargo-culting the docs, I don't really know texinfo.)

> (did you run it?).

I tested my edits by running `make install-info`, killing the *info*
buffer and starting anew with C-h i and navigating down.  I assumed that
did all that needed doing, as my changes were in fact installed and
browsable.  I did not notice any errors from the make runs.

(That was a bit cumbersome, btw.  Is there a better way of testing info
output?)

What I do is run "make", then "M-x revert-buffer RET" in the *info*
buffer.
