[Matlab-emacs-discuss] emacs with Matlab R2009a student version on 64 bit Linux Ubuntu

[Chad B. <cal...@ma...>]

All,

I'm attempting to use GNU Emacs 23 as my Matlab editor, but I find it is
unable to launch matlab (using C-c C-s) because of the following:

> matlab: No MATLAB bin directory for this machine architecture.
>
>            ARCH = glnxa64

I have no problem launching matlab because I have the command 'matlab'
aliased as "matlab -glnx86 -desktop", but this is apparently not the command
that emacs is using when it attempts to run my code.

Do you know how to fix this?

Thanks,

[Matlab-emacs-discuss] A few queries

[Jonathan H. <JON...@sa...>]

I have been using matlab-emacs and I love it, and I am just wondering if 
there is a way to customize a couple features

1) I would like to turn off the feature that automatically puts in '...' 
and a newline; even when I do put those in matlab-emacs puts them in in 
different places from where I would.

2) I would like to be able to press <space> or something to get rid of 
the Completions buffer, or better to make it disappear automatically on 
typing, leaving behind the buffer it replaced (or if it didn't replace a 
buffer killing the frame); it is very annoying that when I want to kill 
it without selecting it I have to switch to it as manually C-x k after 
it replaces a source file I am editing, particularly when I am running 
it in a terminal (e.g. when I am running a process on a remote machine 
through screen).  Is that possible?

I am sorry; I do not know emacs Lisp and do not currently have time to 
learn it, so I cannot do too much to help myself...

Thanks,

Jonathan

Hi - Running R2009b in emacs via matlab-shell on linux, in order to match this error


??? Undefined function or variable 'a'.

Error in ==> foo at 3
z=a


I had to change gud-matlab-error-regexp from

        (concat "\\(Error \\(?:in\\|using\\) ==>\\|Syntax error in ==>\\|In\\) "
                "\\([-@.a-zA-Z_0-9/ \\\\:]+\\)\\(?:>[^ ]+\\).*[\n ]\\(?:On\\|at\\)\\(?: line\\)? "
                "\\([0-9]+\\) ?"))

to

        (concat "\\(Error \\(?:in\\|using\\) ==>\\|Syntax error in ==>\\|In\\) "
                "\\([-@.a-zA-Z_0-9/ \\\\:]+\\)\\(?:>[^ ]+\\)?.*[\n ]\\(?:On\\|at\\)\\(?: line\\)? "
                "\\([0-9]+\\) ?"))

Seems like requiring the parenthetical expression in the middle of second line is a problem.  That makes it work for this one error, but don't know what its purpose is and so don't know if it'll break it for other error msgs.


Another weird thing .. with the modified version, it doesn't detect the error message and linkify it until the 2nd or 3rd time I run foo.m (starting from a fresh matlab session).  Is that normal?

Re: [Matlab-emacs-discuss] Syntax Highlight doesn't work well

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

Hi,

This is an issue with the Emacs configuration for font-lock.  If you examine the doc for this variable with C-h v:

font-lock-maximum-decoration

It shows that if you set it to t, it will use higher levels of font locking.  Matlab.el uses this variable to highlight only a minimal amount of stuff with the default configuration.

Re: [Matlab-emacs-discuss] open selection.

[David C. <dav...@fr...>]

Hi Assaf,

I'm not a matlab-emacs expert, so there might be a way to just do that with
matlab-emacs.
However, the way I do it relies on emacs tags, which brings other advantages
(and surely drawbacks).

Download and install the latest version of exhuberant ctags
(http://ctags.sourceforge.net) as it natively supports matlab now (with
older versions I had to use complex regexps to parse matlab source files)

Then you can generate a tags table in the current directory with the
following shell command (do not remove the final "-")

In Windows:
dir /b/s *.m | ctags -e -o TAGS -L -

Or in Linux/Unix:
find . -follow -type f -name "*.m" | ctags -e -o TAGS -L -

Then instruct emacs to use this file, with M-x visit-tags-table.
Now you can jump to a function definition with M-x find-tag

If you want to just point to a function and open the source code for it, you
can just add to your .emacs something like:

(define-key matlab-mode-map [(C-return)]  (lambda () (interactive)
(find-tag(find-tag-default))))

What I find very convenient is that you can come back to the point where you
invoked the find-tag command with something like

(define-key matlab-mode-map [(C-backspace)] 'pop-tag-mark)

Now (C-return) and (C-backspace) respectively allow you to go lower and
higher in the functions call tree !

Hope that helps,
David.

Thanks for your fast answer. It's a beginning of solution.
Appending all the commands with commas is not really equivalent to fully 
hiding the commands but it helps to decouple the commands printing from 
their outputs.

Perhaps something equivalent but slightly more robust would be to embed 
the cell into a kind of multiple lines eval().

For instance, if the cell is

<code>
%% Cell 1
cmd1;
cmd2;
cmd3;

%% Cell 2
...
</code>

the Matlab shell (through the lisp file matlab.el) would have to launch

    eval(sprintf(cellstr))

where cellstr is the full string containing the text

"%% Cell 1
cmd1;
cmd2;
cmd3;"

i.e., cellstr = '%% Cell 1\n cmd1;\n cmd2;\n cmd3;\n' with perhaps some 
care for doubling the apostrophes inside.



Another point I was wondering, perhaps easier to implement, is how to 
program the "Run Cell and Advance" of Matlab,
i.e. running the current cell and make the pointer jump to the beginning 
of next cell in the editing of the script file.


I regret that I'm not sufficiently specialized in lisp to program myself 
these two features.
My emails could be interpreted simply as a wish list for your mode.
If it is too hard to implement, no problem. This mode is already very 
handy as it.

Best regards,
Laurent

Very nice work!, specially the "cell mode" which was missing from the

About this mode, how can I modify the configuration so that the "Run

I mean, currently, if in a given matlab script I have

%% Cell 1

cmd1;
cmd2;

when I run Cell 1 by launching "Run Cell" inside it, the "Matlab Shell" 
display

<output cmd3>

However, I'd like to restrict the Matlab Shell display to the only

Do you think it is possible?
Displaying the cmds induces sometimes a mess in the output of a cell.

Hi all,

Sorry for the late reply, I have been busy and didn't want to report  
back before I had done my best to make both solutions work. I could  
not make your solution work David but Eric's shell script did the job.

For os x users with the same problem:
I created the shell script described above
Added the folder to the search path
Changed the file permission
Added these lines:
         % Personal change to handle the space in emacsclient -n
         % -------------------------------------------------------
         clientcommand = 'myEmacsclient.sh';
         % -------------------------------------------------------
in the emacsinit file located in /some/path/matlab-emacs/toolbox/ just  
above the line
com.mathworks.services.Prefs.setStringPref('EditorOtherEditor',  
clientcommand);

I should mention that there are still problems with the all the links  
(If i find a solution i will post it), but the edit command now works  
as it should.

Cheers
Daniel

I have encountered the same problem on windows, where adding "-n" to the emacsclient options causes it not to be found, most likely due to the space in the command.
The workaround I have found on windows is to change startup.m as follows:

if (ispc)
    emacsinit('"emacsclient --alternate-editor emacs -n"');
else
    emacsinit;
end

Notice the double quotes within the single quotes... I haven't tried it on linux, but Eric's suggestion should certainly work.

As far as the links for error messages are concerned, I'm also experiencing problems, with all matlab releases (R2006a, R2008a, R2009a).
In particular error messages of the kind:

??? Error: File: myscript.m Line: 57 Column: 15

do not seem to be covered by the regexp.

But great work, Eric ! You don't know how much I value what you've done, but I really, really regret Mathworks' decision to have dropped EmacsLink support...

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

[evelina d. <eve...@ui...>]

Hi Eric,

thanks a lot for the developing and updating of the matlab-emacs code. 
It sometimes works fine for me -- in matlab-shell under emacs some error 
messages are links, other are still not. Funnily, errors with more 
dependencies seem to work. Simple errors in dump test files do not (like 
one-line files [1+1+ ]).

One hint for other users who have problems with the emacs matlab shell. 
I had to do some cleaning! First, updated to the new Matlab R2010a (was 
using the test version sill) and eliminated old toolboxes. The problem 
was that still an old opentoline.m was used. Now matlab uses the one 
provided in matlab-emacs/toolbox (test: error messages in the native 
matlab command window all link to and open emacs perfectly!!!). Second, 
I had to clean matlab.el and matlab.elc from the emacs-goodies-el folder 
--I guess these have been used instead of the updated matlab.el. Hope 
this helps.

Thanks,

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

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

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

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

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

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.

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

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

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

Hi,

The links in the shell buffer may do one of two things.  They will either cause local code to run, like 'find-file-other-window', or it will ask MATLAB to execute the 'opentoline' or 'edit' commands.  If the anchor in the output text is a matlab: style anchor it may cause MATLAB to run that code.  If so, MATLAB will execute 'emacsclient' with some arguments and then your running emacs will pick up on that.  This is similar to if you ran MATLAB and Emacs separately, and changed the editor to be emacsclient.

Anyway, a simple test is at the >> prompt in matlab-shell to type:

>> edit ls

And see if that brings up ls.m in Emacs.  If not, you may need to start the Emacs server with 

M-x server-start

Or some equivalent in you .emacs.

Then try from the Unix shell to type:

$ emacsclient foo.txt

And see if that works.

Eric

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

Hi all,
During my six years at the university matlab-emacs  have been my  
weapon  of choice for editing. During christmas I saw the matlab-shell  
in action and I definitely want to change my workflow to incorporate  
it. Sadly I am unable to get it to function without major limitations.  
Assuming that I was just making an obvious beginner mistake I have  
been watching the mailing list since new year hoping to get some  
pointers on how to go about.

It looks like others are having similar problems, but I have yet to  
see a solution to my main problem: All links are present (mouse  
changes when i scroll over them) but pressing have no effect. I  
suspect the reason can be found in the error messages I receive when  
starting up matlab-shell:
   - Error in menu-bar-update-hook: (void-variable gdb-active-process)
   - Warning: Bug in matlab-shell-mode: it forgets to call `run-mode- 
hooks'
   - Error in menu-bar-update-hook: (void-variable gdb-active-process)
Googling has not helped, and I really don't know where to start.

In addition to this there is the problem of tab completion. When  
trying it I only get the message:
    - ad-Orig-error: No tags table loaded; try M-x visit-tags-table

My setup is GNU Emacs 22.3.1 (i386-apple-darwin9.8.0, Carbon Version  
1.6.0)
  of 2009-09-30 on braeburn.aquamacs.org - Aquamacs Distribution 1.9
with matlab  7.9.0.529 (R2009b) and I presume the latest  version of  
matlab-emacs

All help is greatly appreciated!
Cheers

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

Hi all,
During my six years at the university matlab-emacs  have been my  
weapon  of choice for editing. During christmas I saw the matlab-shell  
in action and I definitely want to change my workflow to incorporate  
it. Sadly I am unable to get it to function without major limitations.  
Assuming that I was just making an obvious beginner mistake I have  
been watching the mailing list since new year hoping to get some  
pointers on how to go about.

It looks like others are having similar problems, but I have yet to  
see a solution to my main problem: All links are present (mouse  
changes when i scroll over them) but pressing have no effect. I  
suspect the reason can be found in the error messages I receive when  
starting up matlab-shell:
   - Error in menu-bar-update-hook: (void-variable gdb-active-process)
   - Warning: Bug in matlab-shell-mode: it forgets to call `run-mode- 
hooks'
   - Error in menu-bar-update-hook: (void-variable gdb-active-process)
Googling has not helped, and I really don't know where to start.

In addition to this there is the problem of tab completion. When  
trying it I only get the message:
    - ad-Orig-error: No tags table loaded; try M-x visit-tags-table

My setup is GNU Emacs 22.3.1 (i386-apple-darwin9.8.0, Carbon Version  
1.6.0)
  of 2009-09-30 on braeburn.aquamacs.org - Aquamacs Distribution 1.9
with matlab  7.9.0.529 (R2009b) and I presume the latest  version of  
matlab-emacs

All help is greatly appreciated!
Cheers
