ssh question...

ssh question...

[Jean-Christophe Helary]

I'm wondering if the following is possible:

Use emacs from my Mac, and use picolisp as the lisp executable to run with slime, but from my ssh'ed RaspberryPi...

Basically, can I call an executable from an ssh session to a different machine ?

Over XQuartz I use an X11 Emacs on a different machine calling, `ssh -Y emacs`, if that helps.

This smells like an A/B question. First the A part (i.e. what you
asked):

As Loris said, the Org Mode trick is pretty nifty. The underlying
machinery is Tramp, and you can get that without Org. Try the
following:

  M-x cd RET

then enter a directory in the remote machine:

  /ssh:me@remote.host:~

  (you are prompted for a password, unless your
  ssh agent session is "open")

and then invoke a shell

  M-x shell

This shell will be on the remote host.

Likewise if you invoke a shell from a buffer which is editing
a file on the remote host (via Tramp).

Now the B part (i.e. what you most probably want):

  https://common-lisp.net/project/slime/doc/html/Connecting-to-a-remote-lisp.html#Connecting-to-a-remote-lisp

It seems to be possible to run the Slime (the Emacs side) <-> Swank
(the Lisp side) connection over the network. I'd definitely try this
first.

Not knowing anything about picolisp or slime, I don't really understand
the question, but would a source block in an Org file on your Mac be of
any help, e.g.

  #+BEGIN_SRC sh :dir /jc@raspberrypi:
  emacs -batch -l ~/.emacs_minimal --eval=='(some-function)'
  #+END_SRC

?

Loris, et all.

Thank you very much for the hints. I've installed ssh mode so I was able to access the machine directly from Emacs but Tramp seems like a really interesting device. I need to understand what it does to see how I can put that to use.

I had tried X11 (Xquartz) but the lack of integration in my mac setup made that less practical.

Thank you again.
