Hi all,

To keep it short, does anyone know how does debugging work? Are there any
documentations for it?

Thank you very much!!
Hera

Hello,

Since I've started using emacs, I use it more and more often (through ubuntu command window). Now i'd like to move matlab to emacs too. Installation is ok, just have some minor questions:

- On the screenshot on [ http://blogs.mathworks.com/community/2009/09/14/matlab-emacs-integration-is-back/ ] you see the usage of 'a workspace' and 'file browser' inside emacs. I can use whos and what, but I'd prefer a fixed 'window/cell' (split command window in 2 or 3 parts) for the workspace variables.  How do I do this?

-Is there a cheat-sheet with quick key bindings available or do i have to define everything in ~/.emacs?

-how does the debugging work?

thanks in advance,
Dieter

Hello,

I am a newbie to emacs-matlab-mode.  I have finished installation and it seems to work.  But I now have a trouble in the original MATLAB environment.

I cannot open any m files in the original MATLAB window, using either double click or 'File -> open...'.  The editor window never comes out after the emacs-matlab-mode is installed.  However, I can still create a new empty file.

By the way, is there a reference card for this mode?  I can find the information of key bindings nowhere but only in the MATLAB menu in emacs.  It couldn't be better if there exists a detailed map of shortcuts.

Thank you.

Kind Regards
Hanzhi

Thanks a lot for your reply!  Yes it was a while ago.  I will probably not
have time to look at this for a little while, but will keep it handy.

Hi,

  I believe you need to add MATLAB's bin directory to your exec path.

Thus, from the command line if you can type:

matlab -nodesktop

and have that work, then Emacs will also be able to find and run MATLAB if you start Emacs from the same shell you start MATLAB from.

Also, make sure your command switches includes the -nodesktop option, otherwise you will get the MATLAB desktop, and not get MATLAB in Emacs.

Good Luck
Eric

Oh, it seems I spoke too soon.

- color-theme seems to break the customization group, but not the
auto-completion

- i had set comint-prompt-read-only in my .emacs file, and that broke
the auto-completion

Hope this helps someone else. I couldn't find any info on debugging
the matlab auto-completion on google. The output with
comint-prompt-read-only looks like:

>> matlabMCRprocess = com.mathworks.jmi.MatlabMCR;matlabMCRprocess.mtFindAllTabCompletions('mfil'), clear('matlabMCRprocess');
ans =

java.lang.String[]:
    'mfilename'
    'mfilt'
    'mfiltcicdecimdemo'
    'mfiltdecimatorsdemo'
    'mfilter'
    'mfiltgettingstarteddemo'

Thanks for your help Eric,

Here's how I got it working for osx lion. (for posterity?)

1) use emacs 24.1 from http://emacsformacosx.com/builds (i had been
using a version I built with cocoa support from brew)

2) cedet 1.1 is what you want, I have no idea what's in 24.1 or how to
figure that out, but I had to download cedet-1.1.tar.gz, extract it
and add the following to my .emacs
(load-file "~/.emacs.d/site-lisp-backup/cedet-1.1/common/cedet.el")

3) there seemed to be some conflicts with the color-theme I was using,
I removed the color-theme settings, and that fixed the broken
customization group: (MATLAB menu -> Configuration). Also fixed the
tab completion breaking. I had the euophoria color-theme version
6.6.0.

Thanks for pointing me in the right direction. I was also able to
compile both cedet and matlab-emacs per their instructions.

Hi,

  I'm not sure about the bug with custom mode.  That just looks like an important face is missing.  Did you override (or have old versions of) custom or widget libraries?

  For CEDET setup, if you use the version of CEDET that comes with Emacs, the matlab setup hasn't been updated to use that yet.  There are dependencies on features in CEDET 1.1 which uses different file names.    When CEDET 1.1 is integrated into Emacs 24, I will need to go back and fix the require statements in the CEDET support in matlab mode.

  For completion, the output you quoted implies that there is an erroneous line breaks in the output string.  Look at  'matlab-shell-completion-list', to see how it builds the command, and make sure there aren't any stray line breaks in the strings.  Perhaps there was a download problem.

Hi David,

Cell mode support in matlab.el can be summed up like this:

% in your major mode
  (make-local-variable 'page-delimiter)
  (setq page-delimiter "^\\(\f\\|%% \\)")

then use forward-page to find the boundary of the cell, and run that region.

There is very little magic involved, and this is a common tactic for other modes as far as I know.

If you intend to copy stuff from matlab-mode, understand that many of the original authors are not around to provide releases that would allow your code to become a part of Emacs or the lisp archive later.

Enjoy
Eric

Subject: [Matlab-emacs-discuss] matlab cell-like mode for Yorick

I am not trying to incite a holy war but will try to be ecumenical and
syncretist:

Yorick is a free, open-source interpreter for numerics (and with a parallel mode) written primarily by Dave Munro at Livermore.  I've always felt if people were choosing tools based on their merits and not inertia, marketing, etc it would be much more widely used.  But that's not my point!

Dave M.'s written a nice emacs package for yorick, and the prime way people are supposed to run yorick is within emacs.  As for OSes, "Linux is nice but I prefer emacs".  It would be very handy to have something like Matlab's cell mode when working with Yorick source - both to navigate source and to execute chunks.

I'm emailing this list since I have almost no familiarity with elisp.  I wonder if it's simple to adapt some of the matlab-mode coding to add a cell capability to editing Yorick source.  If someone is willing to hold my hand or point me to the relevant .el matlab source, we'd be forever grateful.

As things stand, the yorick emacs package lets you send the selected region to the yorick interpreter session for execution.  It just wastes time to constantly select a chunk, execute it, edit it a bit, re-select, etc.

Thanks!
Dave

time to constantly select a chunk, execute it, edit it a bit, re-select,
etc.

Hi,

  One flag you can modify to control how much memory is used is comint-buffer-maximum-size, where comint is a utility matlab-shell uses to interact with MATLAB.  That controls how much text is in the buffer.

  I'm going to guess that is not the problem though.

  MATLAB shell has a feature where it scans the MATLAB output for things to highlight, such as error messages, anchors (like urls), and stacks, which enables you to click on some text for some action.  This works by keeping a buffer of text matlab has recently output and scanning it for those things.  When it finds something, it converts the text into urls, etc.

  In theory, it should only keep 1 line of text or close to it, and be periodically flushed.  You can test that by checking the value of gud-marker-acc from in your matlab-shell buffer.  (where gud is part of the Grand Unified Debugger, which is part of Emacs.)

  M-: gud-marker-acc RET

  If it has grown super huge, then it would indeed get very slow, since every time MATLAB output text it would be searching the buffer for errors, and probably re-tagging old errors.

  The key would be figuring out why the clear conditions aren't met.  You can find that in a bit of code like this:

    (if (and matlab-prompt-seen ;; Don't collect during boot
	     (not frame) ;; don't collect debug stuff
	     (let ((start (string-match gud-matlab-marker-regexp-prefix gud-marker-acc)))
	       (and start
		    (not (string-match "\n" gud-marker-acc start))
		    ;;(not (string-match "^K?>>\\|\\?\\?\\?\\s-Error while evaluating" gud-marker-acc start))
		    )))
	;; We could be collecting something.  Wait for a while.
	nil
      ;; Finish off this part of the output.  None of our special stuff
      ;; ends with a \n, so display those as they show up...
      (while (string-match "^[^\n]*\n" gud-marker-acc)
	(setq output (concat output (substring gud-marker-acc 0 (match-end 0)))
	      gud-marker-acc (substring gud-marker-acc (match-end 0))))

in matlab.el.  It will require a bit of analysis to see why it is failing.  

Good Luck
Eric

Subject: [Matlab-emacs-discuss] Memory Leak?

Hi all!

I was really delighted to see an extension to a free editor that allows for usage of the Matlab debugger, etc.
I installed the whole set of functions using dl_emacs_support. After a bit of fiddling with my .emacs file I have everything running.

The problem that I encounter though, is that when using matlab-mode, Emacs' memory will steadily rise, also maxing out CPU load, up until the point I need to kill emacs because it does not respond any longer. I have the feeling that the problem lies with the  communication between Emacs and Matlab, because before starting Matlab, everything goes well. I also noticed that upon every communication with Matlab (like when completing symbols etc), I get a new line + prompt sign (>>) in the matlab-shell window.

For example, I've got some Matlab code that I'm debugging, and after stepping a few times through the code, emacs hardly responds, CPU load is 100% and memory is (according to top):
Virt: 2244M Res: 1909M (or about 2Gb).

The process of memory growth seems to go exponentially: Each attempt to access emacs makes the increase go faster and faster.

I'm using Emacs 23.3.1 on Kubuntu 12.04 and Matlab R2011b (7.13.0.564).

If anyone knows any solutions, or might point me where to look, I'd be really happy.

Kind regards,

Jan-Pieter

High! Everyone,

I am new to Emacs and have a few dummy questions.

1. Running 'dl_emacs_support' in Matlab environment downloaded some .el
files. How could I use them?
2. How do I start Emacs Matlab mode?
3. Do I need Admin authority to install Matlab mode for emacs?

Thank you very much!

However I would recommend to have the variable

yes of course, but then I have still to change the directory
manually.

That is: my *MATLAB* shell is in dir1, I have a matlab file
at hand (which is in dir2) and run `matlab-shell-save-and-go'
but it does not work because this file is in a different
directory. As I said in MS windows a window pops up.

Now in linux I have to switch to the matlab-shell run pwd
and then run cd dir2. That is very cumbersome.

So I came up with the following solution which I can fire up
in the file

(defun matlab-cd-dir-actual ()
  (interactive)
  (matlab-shell-run-command
   (concat "cd " (file-name-directory (buffer-file-name))))
  (message "You have changed the *MATLAB* shell to the current directory."))

This function is sort of overkill it is executed always,
better would be to have a variable which checks whether the
file is in the directory where the *MATLAB* shell runs.

Uwe Brauer 

Hello

The following works in windows. I use the built in editor
and when to run the entire file, however the command shell
is in a different directory. Then a windows pop up telling
me this and offering me: either to add the current directory
to the path or to change the command window prompt to the
directory of the file, which is the option I almost ever
chose.

I thought that might not to difficult but then as a starter
I cannot find a variable which tells me in which directory I
started the matlab-shell.

Agreed. For a quick personal hack it might be enough to hook into the
C-x space etc commands, but to do it right you would want to query
matlab.

I looked at gud.el & gdb.el, and I think that getting the breakpoints
to display will be harder than keeping track of them. gdb.el has a
bunch of code to display breakpoints using overlays, but it's not at
all obvious how one would go about re-using that code. Ideally it
would all be abstracted into gud.el, but that looks looks like a big
job for a gud/gdb novice. Even if I just wanted to get it working for
matlab stuff, there would a lot of work to figure out exactly what to
copy over into matlab.el. Probably not a good first project for a
emacs lisp newbie.

In principle yes, that would be fine.
In practise however, many things can alter breakpoints. E.g. when you issue
"clear all" from matlab, a side effect is that all breakpoints are cleared,
and emacs wouldn't notice a thing.
I'm sure we can imagine plenty more scenarios, and if emacs doesn't
constantly query matlab for the list of breakpoints, it would quickly get
out of sync.

I was thinking that as long as you only set breakpoints from within
emacs, you wouldn't need to query matlab, and that would make things
simpler. That thread mentions a couple pages of code, which doesn't
sound too bad too me ... but that doesn't mean I'm volunteering to
write said code ;-)

But I've never done any real emacs lisp programming, so maybe writing
something to hook into GUD would be a good first project. I will email
the list if I come up with anything.

Thanks for the replies!

This was shortly discussed in this message:
http://sourceforge.net/mailarchive/message.php?msg_id=28513597

For matlab-shell to keep track of the breakpoints is not impossible but a
little tricky, because it would have to constantly query matlab with
"dbstatus".

Everything would be much easier if matlab was itself sending a message to
matlab-emacs whenever the list of breakpoints changes (e.g. all breakpoints
are cleared, or a new one is added). This feature used to be present with
EmacsLink, but has now disappeared.

My personal take on this is that if enough people complain to MathWworks
directly (not Eric), then they'll (perhaps) do something about it.
As I can't remember where my breakpoints are... I just stick with R2008 and
EmacsLink for now...

Thanks for the response! I mostly remember my breakpoints, so I guess
I'm mostly a good programmer!

But in the case where you are setting and clearing breakpoints through
GUD, shouldn't it be easy for GUD itself to keep track of which lines
you have set breakpoints on? Especially since breakpoints are cleared
every time you save. Even if you set breakpoints through dbstop
commands in the matlab shell, it should still be able to keep track.

Is there something about this that makes it much harder than it seems?

The basic version of gud that integrates in a lot of basic command-line debuggers doesn't support stop sign icons.  There is a special version of gdb w/ gud that does support the stop signs, but it depends on features in gdb to work.  Older versions of MATLAB supported an API we used to use to show stop signs for MATLAB debugging, but when those undocumented APIs changed, we lost that feature.

The philosophy is that good programmers can remember where they put their breakpoints, the same way good programmers in Emacs can remember where they set the mark, but I think it is mostly just that it's hard to implement against a random debugger sub-process that doesn't support triggers.

Subject: [Matlab-emacs-discuss] How can I get emacs to display a stop-sign icon when I set a breakpoint?

(I also posted this question on Stackoverflow, so feel free to answer there if you like)

I'm running emacs 23.4 on OSX, obtained from emacsformacosx.com. I'm writing matlab code, using the latest code from matlab-emacs.sourceforge.net.

I can set breakpoints and step through matlab code with no problems.
However, when I set breakpoints, no "stop-sign" icon appears next to the lines that have breakpoints. The arrow icon indicating the line on which you are stopped *does* appear.

I've seen emacs screenshots online that show stop-sign icons, but I can't find any GUD documentation on this.

How can I get these icons to appear? Is this a problem with matlab-mode, or something in my setup?

Thanks,

Dan
