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

Hi,

In the past, I know I've posted that this worked for me.  I'm not sure what changed, but my MATLAB is now outputting something different, so I was able to reproduce the problem as described here.

The issue I see is that errors for me used to be prefixed like this:

{??? Error in

And now they are not.

I've re-written and checked in a series of changes that are robust to this lack of error text prefix, and I ran some error and debugging samples through my MALTLAB shell, and got the errors to get hyperlinked, and the debugging is also still working for me all in the matlab-shell.

If you experienced this problem, you can get the latest from CVS and give it a try.  Hopefully it will work with both variations of output.  Let me know if there are any more issues.

Thanks
Eric

Hello. Thanks for the hints and all the work on this packages. Here is a just my two cents: 
Both, "$ emacsclient foo.txt" in the terminal and ">> edit someting.m" in matlab-shell (via emacs) or in the native matlab command window both open my default emacs client (aqua on mac, snapshot on linux). Also, warnings do provide correct clickable links for emacs. However, the error messages in the matlab-shell provide no links. In the native matlab command window there are links that open the matlab editor, not emacs (although edit opens emacs!). So probably there is something wrong with editorservices.openAndGoToLine functions ?? -- beats me.
