Re: [Matlab-emacs-discuss] fprintf/disp output to another emacs buffer ?

Hi,

When you start MATLAB in the matlab-shell in Emacs, it causes Matlab to run 'emacsinit'.  In Emacs init, it sets up emacsclient as the default editor.  If your Emacs uses 'server-start' the, typing 'edit' in Matlab will cause the file to open in Emacs.

Dear all,

Based on the previous exchange of emails with Eric, I would like now to standardize a bit this ability to redirect fprintf output to a shell.

In particular, I'd like to design the equivalent of a figure in matlab but for text, let's call it a "message box", so that text messages are sent to it.

More clearly, I'd like to achieve something like

%% Opening a new buffer in emacs with a shell running inside  >> open_msg_box

%% get the current message box opened (a label to it)  >> gc_msg_box ans = 'ttys0'

%% print a message from matlab to this shell  >> message("Hello World");

Here is my related question:

Do you know if there is a way (e.g. with emacsclient) to open a new emacs buffer from matlab (running inside emacs in matlab-shell) and to run something inside (like "shell") ?

Best,
Laurent
