[Matlab-emacs-discuss] matlab-shell-mode for existing matlab process

[Tristan N. <tri...@gm...>]

Hi, great tool!

I was wondering if it's possible to connect to a running matlab session
and designate it as the current *matlab* M-shell?

I am running a remote (ssh) matlab, which works by editing the matlab.el
matlab-shell command to an ssh script.

However, it would be most amazing if I could connect to an already
running matlab process (in the background on the server) via terminal,
and then just 'make' that shell my current matlab shell in emacs, with
something like 'matlab-shell-mode'.

Also, it would be great to be able to have an interactive matlab-shell
with default 'matlab' as command, but the possibility to change that
command, so to be able to launch remote matlabs without having to change
matlab.el every time...
Maybe that would even elegantly solve the above process by using a
command that just connects to the running matlab and puts it to the
foreground? I wouldnt mind doing that manually with a bash command.

Any chances to integrate that?

cheers,

Tristan

Hi,

On your remote system, start emacs in daemon mode.  Then start matlab shell.  Then, you can connect to you emacs and thus your matlab-shell via the emacsclient command any time.   Emacs stays up, matlab stays up.  Plus you can move from machine to machine and always connect to your original matlab session.   I *think* this is what you want?  

You can do something similar with your local emacs and tramp.  If you are sitting on a remote filesystem (M-x cd remote_file_system) and then M-x shell, you can start matlab up from that shell and it won't go away.  But, that shell is not a "matlab-shell".

Hi,

thanks for the answers,

@Larrabee:
the first one really isn't what I want since I want to use my local
emacs with local scripting files, being the newest version with
org-babel integration etc, to interact with the remote, detachable
matlab. This would be much easier than to potentially periodically ask
administrator to update the emacs installations and/or update the
configuration on various servers myself, and having problems with keys
not being sent right  (e.g. Capslock -> Ctrl).

And I haven't quite figured out how to use tramp (except if it runs
anyways in the background and its the default matlab via ssh in emacs
terminal-emulator solution), but the whole Idea is to have it interact
with my script as *Matlab* in matlab-shell mode anyways.

@Stefan:

That does work beautifully and simply.
and with the ansi-term is even better! I just fought with not being able
to run tmux in emacs term or shell, and didn't know about ansi-term
now I can do, to start my session with local script and remote matlab:
M-x ansi-term
TERM=screen ssh server
M-x rename-buffer RET *MATLAB*
tmux
matlab

When done, distach Matlab by tmux command:
C-b d

Now I can close everything, and reconnect with the same procedure as
before, only this time using:
tmux attach


, and my matlab is still open. Awesome!

I will worry about a function for all this another time, great to have
it working! Thanks!

and
@Larrabee:
No, for me the commands work fine, only if there is already a character
given on the command prompt it doesn't ignore it but adds it to the
command from the other buffer, resulting in an error

cheers
T

All you have to to do is to rename the buffer to *MATLAB*.  Then it behaves like the matlab-shell, i.e. you can send code from matlab code buffers, etc.  You could use "rename-buffer", i.e. "M-x rename-buffer", or use the following function (put the following code into ".emacs.d/init.el").  Restart your emacs and then "M-x rename-matlab".

(defun rename-matlab ()
  "Renames the current buffer to *MATLAB*. Useful when running several matlabs."
  (interactive)
  (rename-buffer "*MATLAB*")
)

Not completely sure how to do that.  I don't think that the matlab-mode must be changed for that.  Instead, you have to figure out how to create an emacs command that creates a new buffer e.g. for an 'ansi-term', then does ssh somewhere, and starts matlab.  Finally you rename the buffer to "*MATLAB*", that's it!  Possibly the people at http://stackoverflow.com/ can help you with writing the necessary elisp code.  I would be also interested in such a emacs command.

Best wishes,
Stefan.

[L. L. S. <ls...@gm...>]

All,

I just tried renaming a *shell* buffer running Matlab to *MATLAB*.  It kinda works, but not completely.  "Run Region" for example, works, but inserts an extra ">" prompt that must be removed by hand, unlike a buffer actually created by "matlab-shell".

Am I missing something?

Thanks, Larrabee
