Re: [Matlab-emacs-discuss] Links and tab completion in matlab-shell

[Daniel H. <dan...@gm...>]

Thanks for the quick response Eric.
I think you are on to something. Running the edit test fails.

 >> edit ls
??? Error using ==> edit at 57
Could not find external editor

Before running server-start emacsclient does not work, after running  
it starts a new emacs buffer as expected. Starting the matlab-shell  
after the server is started does not help.

However, after I start the matlab-shell there is a line printet in the  
matlab promt:

 >> addpath('/Path/to/Matlab/Emacs/Matlab/toolbox,'-begin'); rehash;  
emacsinit('emacsclient -n');

I am suspecting it is the last one that is the perpetrator. I hunted  
it down to line 4160 in matlab.el

(defvar matlab-shell-emacsclient-command "emacsclient -n"
   "The command to use as an external editor for MATLAB.
Using emacsclient allows the currently running Emacs to also be the
external editor for MATLAB.")

Checkin what is does in emacsinit.el i found this on line 11-14

if nargin == 0
             clientcommand = 'emacsclient -n';
         end
com.mathworks.services.Prefs.setStringPref('EditorOtherEditor',  
clientcommand);

Simply running

 >> com.mathworks.services.Prefs.setStringPref('EditorOtherEditor',  
'emacsclient');

fixed so that edit opens a buffer in emacs. I changed line 4160 in  
matlab.el and 12 in emacsinit.el and hoped this would solve all my  
problems.  Now edit works but the error links are still missing.  
Testing the old configuration again I don't think they ever where  
there. It is only the statements that appear clickable (makes the  
mouse change when I scroll over) not the errors.  Sorry for the  
misinformation in the previous mail.

I have no Idea what to do next
Cheers
Daniel
