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

Hi,
I had posted yesterday about the change you found yesterday, but I didn't get a copy of my email back from the mailing list. In effect, the output text of MATLAB changes, so I updated the matlab-shell code to be (I hope) robust to that class of change.
I'm not sure why adding "-n" to your emacsclient script causes it to not be found. If the problem is related to the space in the command, a simple workaround is to create a shell script like this:
myemacsclient.sh
--------------
#!/bin/sh
emacsclient -n $*
--------------
And then use that shell script instead.
Eric

Hi,
I had no idea that the development was so dynamic. Last update 3 hours
ago, nice. Anyway, I have the latest CVS so I do not believe my
problem is there. It might be that I and Evelna have different issues.
Testing some more with regard to the edit function in matlab:
>> emacsinit('emacsclient');
>> edit ls <-- works fine,
but opens a buffer that needs to be closed using C-x #
>> emacsinit('emacsclient -n ');
>> edit ls
??? Error using ==> edit at 57
Could not find external editor
Trying the same in terminal
emacsclient test.txt <-- works fine, but opens a buffer that
needs to be closed using C-x #
emacsclient -n test.txt <-- works fine, normal buffer
From the manual I have this
-n, --no-wait
returns immediately without waiting for you to
"finish" the
buffer in Emacs.
which sounds like the behavior one wants when debugging. I will
continue my search, but to be honest I am quite far from home. Hope
the updated matlab-emacs works for you Evelna. Thanks for the help Eric.
Best
Daniel
