Re: [Matlab-emacs-discuss] Possible bug: emacs unresponsive if hit RET multiple times at the end of matlab command

[<rp...@gm...>]

I can reproduce that with the emacs version on ubuntu (23.1.1).

I encounter a related problem when, while running matlab-shell, the
connection to the licence server is dropped - emacs (all of it, not
only the shell) remains completely unresponsive until the connection
works again. This is a serious issue since I can't even save my stuff
if the connection fails and I can't get it up again.

[Matlab-emacs-discuss] Possible bug: emacs unresponsive if hit RET multiple times at the end of matlab command

[Leo A. <dn...@gm...>]

Tested with Matlab mode 3.3.1, several recent versions of Emacs.
Steps to reproduce:
M-x matlab shell
pause(10)
RET RET RET

Here, pause(10) can be any command that doesn't return immediate result.

Expected result: Matlab command runs in matlab-shell buffer, Emacs can
be used as normal.  Observed result: Emacs quits responding to
keyboard input until the command exits.

This Is a serious problem, as it presents an easy way to accidentally
hose your Emacs session when working with long-running commands.

Can anybody reproduce and/or comment?

Re: [Matlab-emacs-discuss] edit m-file from within matlab-shell

[Cláudia S. <cla...@gm...>]

Update on the edit m-file issue:

The data posted by me previously was incomplete; I forgot to mention
that the error occurred only with MAC OS X.

Another user found out that the code in matlab's edit.m to open files on
a mac had a peculiar feature: it quoted the command line, performed a
unix which on it and then tried to run the quoted command version.

As we had entered clientcommand = 'emacsclient -n' the quoted version
fails the which command and, of course, the unix shell execution.

An initial correction action was to remove the quotes and not to invoke
which, in the edit.m


Does anyone have a better alternative?


Thanks!

[Matlab-emacs-discuss] Bug in matlab-shell-run-region

[Cláudia S. <cla...@gm...>]

Hello All,

I just bumped into something looking suspiciously like a bug.

symptoms:
while running matlab-shell-run-region over matlab code including
comments, all the code followed by the commented line is no executed.

causes:
In the definition 'matlab-shell-run-region @ matlab.el, while creating
the 'command binding, there is a 'while loop labeled as ;; HACK FOR
NOSHOW whose action is to replace '\n' by ',' regardless of the present
line being or not a comment.

aesthetic considerations:
I do prefer to see the lines ran in the prompt as they were layered out
by me in the code file. I can understand some people might wish to
completely remove those lines from the matlab-shell buffer; that would
certainly be another effort, different from simply concatenating
everything in a big one-liner...


the cure:
Just comment the hack code...


cheers,
Cláudia

[Matlab-emacs-discuss] edit m-file from within matlab-shell

[Claudia S. <cla...@gm...>]

Hi,

I'd like to execute the edit command on the matlab prompt, inside the
matlab-shell mode, and see a new emacs buffer with the contents of the
edited file.

How can this be done?

Thanks!

[Matlab-emacs-discuss] Add local key binding to matlab-shell-mode

[Guangran K. Z. <gua...@ma...>]

Dear all,

I would like to add some local key binding to the matlab-shell mode by 
adding the following code to my .emacs file

=========================================================================
(defun my-matlab-hook ()
   (local-set-key "M-p" 
'(matlab-shell-previous-matching-input-from-input n))
   (local-set-key "M-n" '(matlab-shell-next-matching-input-from-input n))
   )
(add-hook 'matlab-shell-mode-hook 'my-matlab-hook)
=========================================================================

The matlab-shell-mode-hook is currently defined in matlab.el file. The 
code above does not link to the hook directly. Would anyone have any 
suggestion on this emacs problem? Thank you.

Thank you guys. Another play of two hours solved the problem. The

There should be no difference. Since everything emacsclient does is to
check if there is an emacs process running and open the file in this
existing process.

I think your configuration should be fine if you add (server-start) to
your emacs config file and use emacsinit('emacsclient -n'). This will
provide the link back to emacs.

Re: [Matlab-emacs-discuss] Config problem matlab-emacs on linux

[Dineva, E. E <eve...@ui...>]

Hi Kevin,

your mail remind's me that I forgot to mention that one also needs to add for Ubuntu to .bashrc:
export EDITOR="emacsclient"

and, as Daniel mentioned earlier, one also needs to add to .emacs the line:
(server-start)

As for searching in the matlab-shell, you can type the initial letters of a command and then browse the history with the up/down arrow keys.

Cheers,

Re: [Matlab-emacs-discuss] Config problem matlab-emacs on linux

[Guangran K. Z. <gua...@ma...>]

Thank you for the pointer.

Using emacsclient does not support the debugging and code evaluation, 
which I have relied on heavily.

changing ~/X11/app-defaults/Matlab

*externalEditorCommand:	$EDITOR $FILE &

does not provide the debugging and evaluation support as well. Thus, 
using emacs-shell, to the best of my knowledge, is my only option. I 
followed the documentation

http://blogs.mathworks.com/desktop/2009/09/14/matlab-emacs-integration-is-back/

Currently, I am missing on the configuration of linking the matlab 
invoked in the buffer back to the current emacs session.

In the meantime, I experimented with the matlab-shell. In comparison 
with invoking the following on a command line,

$ matlab -nodesktop -nosplash

I found matlab-shell is nice to use, as I could edit the command in the 
buffer. One improvement that I observe, is that if you type the first 
letter of some previous command, alt-p will bring the immediate previous 
command, but will not bring the previous command that starts with the 
same letter.

Please ignore my proposal about editing the emacsinit.m. This is

> emascsinit('emacs')

Is equivalent to setting the Editor/Debugger in your matlab
Preferences. You can place this in your startup.m file, but it won't
help since it will always open a new process.

I think the best way is to install an emacs version that comes with
emacsclient (are you sure that your emacs on ubuntu has no
emacsclient?).

There is also an other advantage to use emacsclient. for e.g. in your .bashrc
> alias "edit=emacsclient -n -a emacs"
With this you can type 'edit somefile.txt' in a console and it will
open the file in your existing emacs process, if there is one,
otherwise it will start one.
Don't forget to add (server-start) in your emacs config file.

Re: [Matlab-emacs-discuss] Config problem matlab-emacs on linux

[Dineva, E. E <eve...@ui...>]

I think one also need to tell matlab to use emacs as default editor 

one can do this via the matlab settings. sorry, do not have my Ubuntu at hand to look up details; 

on mac it's via preferences when you have a malab window open. e.g., calling 'doc edit' via the matlab-shell has Preference settings under the File menu

'doc edit' provides some info on setting up an alternative editor with the -nodisplay startup option 

unfortunately this does not work for aquamacs on the mac; but similar settings were just fine on ubuntu with (regular, snapshot) emacs  

hope this helps a bit and a Happy New Year!

But in this case each time you call edit, the file will be opened in a

matlab-emacs.

Dear all,

I am configuring matlab-emacs with

Ubuntu 10.4,
Emacs 23
CEDET-1.0pre7
MATLAB r2010a

I intent to run Matlab within emacs through "matlab-shell". Currently, 
this command runs successfully. However, when I type "edit", nothing 
happens on the command prompt and there is no buffer created for the new 
file. I could not find any error message and matlab prompt is

There is no "emacsclient" installed on my machine. Given the "addpath

missing to link the matlab to the current emacs.

Any comment on how to debug this problem? Thank you.

Re: [Matlab-emacs-discuss] matlab-emacs tab-completion problem

[Eric L. <Eri...@ma...>]

Hi,

The TAB key is hooked up to send those messages to MATLAB to get the list of completions.  It works by putting the process filter (that Emacs uses to interpret process output) into a mode that waits for the next prompt, and collects all the output into a string which Emacs then processes to create a completion buffer.

It appears to not work for you today. ;)

I tried using the latest version of matlab-shell from CVS and completion worked for me.  I tried hitting C-g in a couple spots to see if I could mess it up, but it worked like a champ.

To debug, you will probably need to look at matlab-shell-collect-command-output.  If it throws an error part-way through, the output you see would be easily explained.

Subject: [Matlab-emacs-discuss] [PATCH] Menu: if matlab shell is active replace "Start MATLAB" with "Switch to MATLAB"

Hello,
I wrote a small patch to replace the "Start MATLAB" menu entry with a "Switch 
to MATLAB" entry when the matlab shell is active. This might look like a minor 
detail but I think it improves the usability. It makes it clear that "Start 
MATLAB" won't start another shell but switch to the existing one.

[Matlab-emacs-discuss] debugging intro?

[Van Z. J. <jr...@mi...>]

I’m looking for a way to use standard Emacs GUD debugging commands (n, c, r,
etc.) for Matlab debugging.  

I’ve downloaded and installed matlab.el.  I see the default customization
uses GUD mode for Matlab shell mode.  Executing a function opens a buffer on
the source with the current location marked with an arrow.  

However, the GUD commands (in either buffer) don’t work.  I still have to
use the verbose Matlab style debugging commands (though alt-P helps).

In matlab.el I see some GUD key assignments:

                (gud-def gud-break  "dbstop at %l in %f"  "\C-b" "Set
breakpoint at current line.")
                …

However, they don’t seem to work in either matlab-mode or matlab-shell.
(They just move point.)

The GUD code may have suffered bit-rot (e.g. hasn't kept up with Emacs), but
it's more likely I'm doing something wrong.

Is there introductory documentation somewhere?  I’d expect it in the CSV
server, or at least a link in the FAQ, but I don’t see anything beyond "GUD
support for debugging programs files".

Otherwise, if "It's working for you", could someone start a debugging
session, execute a few commands, run "M-x view-lossage" and post the result?
:-)

I'm using these versions:
   matlab.el version 3.3.1
   Matlab 7.7.0.471 (R2008b)
   Emacs 22.2.1
   Linux 2.6.32

             - Jim Van Zandt

Re: [Matlab-emacs-discuss] Tab completion

[Jean-Francois L. <jfl...@gm...>]

Hi Eric,

I just tried updating emacs to the most recent version (23.2.1) and I
still get the same behavior... of course that's not to say there's no
bug in emacs ;) but I'll take any idea you might have!

Thanks again!

Re: [Matlab-emacs-discuss] Tab completion

This sounds like a bug in the terminal version of Emacs.  If pressing C-l shows the missing text, then there isn't much the matlab-shell code can do about it.

Subject: [Matlab-emacs-discuss] Tab completion

Hi,

I'm trying to get tab completion in matlab-shell mode to work, but I'm hitting a wall right now. I'm running everything on Mac OSX 10.6.

1. Using Aquamacs works perfectly. I get the expected completion behavior when I hit <tab> after a half-spelled command on the Matlab prompt within the matlab-shell mode. 

2. However, when I try to do the same in an emacs process launched within Terminal.app, hitting <tab> moves the cursor by a few spaces to the right, and does not display the auto-completion options. In fact, if I type:

imsho<tab> <enter>

then it displays

imshow
??? Error using ==> imshow>preParseInputs at 309
...

which means that hitting <tab> does complete 'imsho' to 'imshow', but it does not actually display it. I've also tried using X11.app and I get the same results. I use emacs on a regular basis but only for simple text editing purposes, so my knowledge of Lisp and .emacs configuration settings is extremely limited... 

Any idea? 

Thanks in advance,
JF

Hi Eric,

Thanks a lot for your prompt answer!

I tried pressing C-l after writing 'imsho<tab>' in matlab-shell, and
nothing happens.

However, when I tried 'M-x matlab-shell-tab', then the auto-completion
works as expected. It just seems like the 'tab' key isn't working
properly?

Maybe updating emacs will fix that, if it is indeed a bug in its
terminal version. I'll try that.

In my customise settings I have:
 '(matlab-shell-command "matlab")
 '(matlab-shell-command-switches (quote ("-nodesktop" "-glnx86" "-nosplash")))

you have to quote each argument it seems.

Is currently in my matlab.el file, and if I put the -nodesktop flag first,
Matlab will not run because the -glnx86 flag doesn't get used for some
reason.  If I put the -glnx86 flag first, Matlab will run, but it runs in
the desktop mode which doesn't work with the emacs matlab-shell mode.  I
think this is a a syntax error.  Does anyone know lisp well enough to help?
