Hi After restarting emacs everything worked as expected. Maybe I am debugging too many matlab files today. So please ignore my message Uwe Brauer |

Hi Maybe my memory does not serve me well, but I swore it was possible, some time ago, to set a breakpoint in a matlab file which I want to debug. However right now the only thing which works is using something like this in the matlab shell >> dbstop in mieuler at 23 and then run mieuler(fun,[0 1],1,100) But I thought using gud-break at line 23 in mieuler would do the same, it does not however. Do I miss something or is this functionally gone, or do I have hallucinations? Uwe Brauer |

Hi For some bizarre reason I was not receiving email from that list for while, so I had to subscribe again (the system did not tell me that I am already subscribed, which is odd since I should be subscribed since several years). In any case did my message from yesterday concerning the branch proposed_changes created by John Ciolfi? I did not push Nathan's change since I am not sure what to do with that branch. I wait a day. If there is no reaction I try to contact John directly. Regards Uwe Brauer |

Hm does not work. This time patch did not refuse it outright as last
time but I obtain.
Hunk #1 FAILED at 24.
1 out of 1 hunk FAILED -- saving rejects to file company-matlab-shell.el.rej
And similar for matlab.el
Ok I see what happens (and why I hate git).

The last commit is mine.

| summary: Fixed TAB completion, debugging updates, warning fixes
which sit as I understand in the branch (bookmark in hg speach)
proposed_changes. (That I would have failed to identify that these 3
commits belong to a different branch would not have happened in
mercurial using named branches, but I don't want to open a flamewar).
I can apply Nathan patch to master but not to the latest commit in that
branch. I think I will commit and push Nathan Changes, and could merge
in later John's changes from his branch.
Did anybody try out the commits in this branch? I seem now to remember
vaguely an email form him mentioning his changes and that he would put
in a branch. I am not even sure that I tested his changes.
Any thoughts before I push? I might wait a day or so more to hear
opinions.
Uwe

Hi,
Here's the patch files, sorry I didn't know what the usual format was. You should just be able to pipe them into 'patch'.

Hi Nate,
Could your provide a diff that provides context (a context diff) ? It isn’t clear how to merge the patch into code where the line numbers may have changed. Ideally, the diff could be intput into the ‘patch’ command.

Sorry about the delay, I had a busy few weeks. Here's the diff for matlab.el, I also included one for company-matlab-shell.el which enables predictions while editing the middle of a line.

Subject: Re: [Matlab-emacs-discuss] Removing extra lines from collect-command-output
That's what I thought the purpose of the newline is, but the documentation for comint-simple-send states that it automatically appends a newline to the command, so it's not needed.
As an aside I think that in the current version of emacs the while loop in the same function needs to be wrapped in a with-local-quit to avoid raising an error (or at least the accept-process-output call does).
Best,
Nate

I wrote that a long time ago, but my vague recollection is that the newline was needed to make the subprocess execute the command. Is it adding a 2nd newline to the end of ‘command’ resulting in the spare line?

Subject: [Matlab-emacs-discuss] Removing extra lines from collect-command-output
Hello,
I've noticed that calling 'matlab-shell-collect-command-output' can result in extra new lines being sent to the *MATLAB* buffer which aren't deleted. When using company-mode to complete text this behavior is pretty annoying since as I'm typing lines are being inserted above the prompt. I believe that the cause of this is the line:
(comint-simple-send (get-buffer-process (current-buffer))
(concat command "\n"))
The newline added to the end of the command causes an extra line to be printed since it's interpreted as execute 'command' and then send a newline. Removing the newline fixes the problem.
This seems like a suspiciously simple fix so I'm wondering why the newline was being appended to the command.
Thanks,
Nate

Hi, Here's the patch files, sorry I didn't know what the usual format was.

Hm thanks I checked and set
(setq matlab-shell-echoes nil)
It does not change
#+begin_src matlab :results output latex :exports results :eval never-export
f=@(t,y)[-t*y^2];
[t,y]=ode45(f,[0 1],1);
t=[t(1),t(end)];
y=[y(1),y(end)];
disp('\begin{align*}')
fprintf('t = [%g \\qquad %g \\quad %g] \\\\\n', t)
fprintf('y = [%g \\qquad %g \\qquad %g] \n', y)
disp('\end{align*}')
#+end_src
Results in
#+RESULTS:
#+BEGIN_EXPORT latex
>> f=@(t,y)[-t*y^2];
>> [t,y]=ode45(f,[0 1],1);
>> t=[t(1),t(end)];

\begin{align*}

t = [0 \qquad 1 \quad >> fprintf('y = [%g \\qquad %g \\qquad %g] \n', y)
y = [1 \qquad 0.666667 \qquad >> disp('\end{align*}')
\end{align*}
#+END_EXPORT
However I wrote a trivial cleaning function which just deletes the lines
starting with >> and I obtain the following
#+RESULTS:
#+BEGIN_EXPORT latex
\begin{align*}
t = [0 \qquad 1 \quad >> fprintf('y = [%g \\qquad %g \\qquad %g] \n', y)
y = [1 \qquad 0.666667 \qquad >> disp('\end{align*}')
\end{align*}
#+END_EXPORT
Which is precisely what I want. I am not able to combine the cleaning
function with the new
org-babel-execute:matlab-shell
Function because
(matlab-shell-collect-command-output code)))
Returns
>> y=[0 5]\n>>
Etc so everything is in one line (with \n) that results when inserted in
newlines of course but running the cleaning function
(flush-lines "^>>" nil nil t)) would delete everything
For me this solution is ok but if somebody comes up with a better
solution, please go ahead, the 2 new functions are
(defun org-babel-execute:matlab-shell (body params)
(interactive "P")
(let* ((current-file (buffer-file-name))
(code (org-element-property :value (org-element-context)))
(result-params (cdr (assoc :result-params params))))
(let ((results
(matlab-shell-collect-command-output code)))
(org-babel-result-cond result-params
results))))
(defun clean-org-matlab-region-output ()
(interactive)
(flush-lines "^>>" nil nil t))
But this is anyhow more relevant for org mode users. I brought up the
issue on their mailing list as well but there was not much interest.

It looks like an echoing feature is turned on, where input into ML is echo'd back out again. There's a variable for describing what ML does since the echo depends on platform or some-such. I think it's been 't' for a long time.
Maybe in your cleaned code, put all the code on one line with no CRs, and sub in a , when there is no line ending. Then you could clean out the input code.
Alternately, put it into a tmp file as before, and run that, and clean out the name of the tmp command.
I don't have a Linux box to test my MATLABs on to fiddle around with echo features. Sorry.

Ok fair enough. I think I made some progress but still have a small
problem, maybe you might remember and help. :-D
John's code consists of:
- cleaning the matlab code in orgmode mode: (font lock stuff etc)
and collect it.
- create a temporally file and insert the clean matlab commands.
- run a external matlab process via
"/usr/local/bin/matlab " "-nodesktop <" m-file
- clean the result and insert it in the original buffer.
So my solution is to use the matlab-shell-collect-command-output
function. So my code is:
- cleaning the matlab code in orgmode mode: (font lock stuff etc)
and collect it.
- run (matlab-shell-collect-command-output code) where code
corresponds to the clean code from step one which John inserts in
temp buffer.
- clean the result and insert it in the original buffer.
The only problem is that the output of the
/usr/local/bin/matlab -nodesktop < m-file
And (matlab-shell-collect-command-output code)
is slightly different.
Take the following example.
f=@(t,y)[-t*y^2];
[t,y]=ode45(f,[0 1],1);
t=[t(1),t(end)];
y=[y(1),y(end)];
disp('\begin{align*}')
fprintf('t = [%g \\quad<file://quad> %g] \\\\\n<file://n>', t)
fprintf('y = [%g \\qquad<file://qquad> %g] \n', y)
disp('\end{align*}')
The external matlab command does not include the fprintf in his output.
I have collected the output of both approaches including the result of
the cleaning function.
So there are two possibilities.
- Modify matlab-shell-collect-command-output so that it behaves closer to
/usr/local/bin/matlab -nodesktop < m-file
- modify the cleaning function (which I don't understand but could
ask John about it).
(when results
;; strip out >>
(setq results (replace-regexp-in-string ">> " "" results))
;; remove first 10 lines that are the header.
(setq results (mapconcat 'identity
(nthcdr 10 (split-string results "\n"))
"\n")))
Any comment is more than welcome. Here is the output of both commands

Ok fair enough. I think I made some progress but still have a small<br>
problem, maybe you might remember and help. :-D<br>
<br>
John's code consists of:<br>
<br>
- cleaning the matlab code in orgmode mode: (font lock stuff
etc)<br>
and collect it.<br>
<br>
- create a temporally file and insert the clean matlab
commands.<br>
<br>
- run a external matlab process via<br>
"/usr/local/bin/matlab " "-nodesktop <" m-file<br>
<br>
- clean the result and insert it in the original buffer.<br>
<br>
So my solution is to use the matlab-shell-collect-command-output<br>
function. So my code is:<br>
<br>
- cleaning the matlab code in orgmode mode: (font lock stuff
etc)<br>
and collect it.<br>
<br>
- run (matlab-shell-collect-command-output code) where code<br>
corresponds to the clean code from step one which John
inserts in<br>
temp buffer.<br>
<br>
- clean the result and insert it in the original buffer.<br>
<br>
<br>
The only problem is that the output of the<br>
/usr/local/bin/matlab -nodesktop < m-file<br>
<br>
And (matlab-shell-collect-command-output code)<br>
is slightly different.<br>
Take the following example.<br>
<br>
f=@(t,y)[-t*y^2];<br>
[t,y]=ode45(f,[0 1],1);<br>
t=[t(1),t(end)];<br>
y=[y(1),y(end)];<br>
disp('\begin{align*}')<br>
fprintf('t = [%g \\quad %g] \\\\\n', t)<br>
fprintf('y = [%g \\qquad %g] \n', y)<br>
disp('\end{align*}')<br>
<br>
The external matlab command does not include the fprintf in his
output.<br>
I have collected the output of both approaches including the result
of<br>
the cleaning function.<br>
<br>
So there are two possibilities. <br>
<br>
- Modify matlab-shell-collect-command-output so that it behaves
closer to<br>
/usr/local/bin/matlab -nodesktop < m-file<br>
<br>
- modify the cleaning function (which I don't understand but
could<br>
ask John about it).<br>
<br>
(when results<br>
;; strip out >><br>
(setq results (replace-regexp-in-string ">> " "" results))<br>
;; remove first 10 lines that are the header.<br>
(setq results (mapconcat 'identity<br>
(nthcdr 10 (split-string results "\n"))<br>
"\n")))<br>
<br>
<br>
Any comment is more than welcome. Here is the output of both
commands<br>
<br>

Sorry for not being more precise.
Inside 'matlab-shell-save-and-go' is infrastructure for building something custom for org-mode. For example, how it looks for a shell buffer and creates on only if needed, and how it updates the history (which you could remove) and how it executes the string. It is similar to run-region in how it works w/ the shell buffer.
In a different part of the thread, you wanted to capture the output to insert into org-mode. 'matlab-shell-run-command' will capture the output to display in a help buffer. You could probably use its mechanisms to capture the output from the shell to display where you need it.
If you want to capture images from any figures created, there is nothing for that. You'd need to add something the matlab-emacs toolbox for capturing and saving images in a way that Emacs could then pick up the files.

Hm suppose the shell is running.
The core of his function are the following lines
(let ((results (shell-command-to-string
(concat
"/usr/local/bin/matlab "
"-nodesktop -nojvm -nosplash -nodisplay <"
m-file))))
So are you saying I should try
(switch-to-buffer m-file)
(find-file m-file) ;? None worked
(let ((results (matlab-shell-save-and-go)
(delete-file m-file)
rest of code)))
Hm this did not work, so most likely I am not taking care of something elementary here.

Ah, sorry I can't be more help. It has been many years since I worked on that code, and I don't use Emacs much anymore. There are accommodations in the function's I referenced for the ML command line to make sure it doesn't interrupting anything a user might be typing in that would be important for your use case.
It might be worth trying the Matlab help stuff in matlab-mode/matlab-shell to see if it still works. This is code that will call help, and put output into a separate buffer. I haven't tested it in ages, so if it isn't working in ML shell, that might explain any issues you're bumping into with org mode.

Yeah I tried to debug it and to understand its structure. The matlab-shell-command is, at least for me, maybe the most complex part of the code. On the other hand the crucial parts of John's code are the lines
(let ((results (shell-command-to-string
(concat
"/usr/local/bin/matlab "
"-nodesktop -nojvm -nosplash -nodisplay <"
m-file))))
So I hoped somebody with a better understanding of the matlab-shell-command could give me a hint, but it seems that the merge between John's code and matlab-shell is much more complicated.

Yes I did and John's code does precisely this. I asked the same question on the orgmode list and John replied. The only problem with his code is that it uses the command line matlab command and so starts every time matlab, when the code is executed.

No that is ok, I hoped orgmode could take that part as well but all my attempts failed.

Hi Nate,
Could your provide a diff that provides context (a context diff) ? It isn’t clear how to merge the patch into code where the line numbers may have changed. Ideally, the diff could be intput into the ‘patch’ command.
Thanks
Eric

Hi,
Sorry about the delay, I had a busy few weeks. Here's the diff for matlab.el, I also included one for company-matlab-shell.el which enables predictions while editing the middle of a line.
Best,
Nate

That's what I thought the purpose of the newline is, but the documentation for comint-simple-send states that it automatically appends a newline to the command, so it's not needed.
As an aside I think that in the current version of emacs the while loop in the same function needs to be wrapped in a with-local-quit to avoid raising an error (or at least the accept-process-output call does).
Best,
Nate

Subject: [Matlab-emacs-discuss] Removing extra lines from collect-command-output
Hello,
I've noticed that calling 'matlab-shell-collect-command-output' can result in extra new lines being sent to the *MATLAB* buffer which aren't deleted. When using company-mode to complete text this behavior is pretty annoying since as I'm typing lines are being inserted above the prompt. I believe that the cause of this is the line:
(comint-simple-send (get-buffer-process (current-buffer))
(concat command "\n"))
The newline added to the end of the command causes an extra line to be printed since it's interpreted as execute 'command' and then send a newline. Removing the newline fixes the problem.
This seems like a suspiciously simple fix so I'm wondering why the newline was being appended to the command.
Thanks,
Nate
P.S I am new to using mailing lists so if I've committed any faux pas in this email please let me know

Yeah I tried to debug it and to understand its structure. The
matlab-shell-command is, at least for me, maybe the most complex part of
the code. On the other hand the crucial parts of John's code
are the lines
(let ((results (shell-command-to-string
(concat
"/usr/local/bin/matlab "
"-nodesktop -nojvm -nosplash -nodisplay <"
m-file))))
So I hoped somebody with a better understanding of the
matlab-shell-command could give me a hint, but it seems that the merge
between John's code and matlab-shell is much more complicated.

Yes I did and John's code does precisely this. I asked the same question
on the orgmode list and John replied. The only problem with his code is
that it uses the command line matlab command and so starts every time
matlab, when the code is executed.

No that is ok, I hoped orgmode could take that part as well but all my
attempts failed.

MATLAB mode has a command to execute region in the MATLAB Shell from a .M file. I see no reason why you couldn't re-use that.
It may be it needs updating to also start the shell, or to chdir if there is a function, or something like that.

Subject: [Matlab-emacs-discuss] executing matlab in org mode files (using the matlab-shell)
Hi
I am using more and more org mode, a long with auctex and matlab.el.
Orgmode comes in handy if I write a document which contains (matlab) code which I want to execute, but the rest of the file maybe text, which I can then export to latex.
So a typical file looks like
Given
\droppoints
\begin{displaymath}
\begin{cases}
\frac{du}{dt}&= -t u^2,\\
u(0)&=1,
\end{cases}
\end{displaymath}
Solve using ...
#+BEGIN_solution
#+begin_src matlab :results output latex :exports results :eval never-export f=@(t,y)[-t*y^2];
[t,y]=mieuler(f,[0 1],1,2);
disp('\begin{align*}')
fprintf('t = [%g \\qquad %g \\quad %g] \\\\\n', t) fprintf('y = [%g \\qquad %g \\qquad %g] \n', y)
disp('\end{align*}')
#+end_src
Now I can execute the matlab code in that org file using
C-c C-c ( org-ctrl-c-ctrl-c, the *one-ring-to-rule-them-all* function in orgmode.
Thanks thanks to a function provided to me by John Kitchin it executes matlab.
It is as follows:
(defun org-babel-execute:matlab (body params)
(interactive "P")
(let* ((current-file (buffer-file-name))
(code (org-element-property :value (org-element-context)))
(result-params (cdr (assoc :result-params params)))
m-file
md5-hash)
(with-temp-buffer
(insert code)
(setq md5-hash (md5 (buffer-string))
mbuffer (format "*m-%s*" md5-hash)
m-file (format "m-%s.m" md5-hash)))
;; create the file to run
(with-temp-file m-file
(insert code))
(let ((results (shell-command-to-string
(concat
"/usr/local/bin/matlab "
"-nodesktop -nojvm -nosplash -nodisplay <"
m-file))))
(delete-file m-file)
(when results
;; strip out >>
(setq results (replace-regexp-in-string ">> " "" results))
;; remove first 10 lines that are the header.
;; matlab license seem to expire soon, so 5 warning lines are added
;; change first 10 to first 15 lines
(setq results (mapconcat 'identity
(nthcdr 10 (split-string results "\n"))
"\n")))
(org-babel-result-cond result-params
results))))
The problem of that code is that it starts matlab every time I execute C-c C-c . There seems to be a python based kernel around which avoids this, but I thought that maybe with a bit of hacking one could use the elisp based matlab-shell and the corresponding functions.
Anybody has an idea, Eric?
Needless to say that I played a bit around but did get it to work....

Uwe Brauer

Hm suppose the shell is running.
The core of his function are the following lines
(let ((results (shell-command-to-string
(concat
"/usr/local/bin/matlab "
"-nodesktop -nojvm -nosplash -nodisplay <"
m-file))))
So are you saying I should try
(switch-to-buffer m-file)
(find-file m-file) ;? None worked
(let ((results (matlab-shell-save-and-go)
(delete-file m-file)
rest of code)))
Hm this did not work, so most likely I am not taking care of something
elementary here.

Right: your code uses the matlab-shell, which writes its results in the
*MATLAB* shell buffer, but I want the result (at least optional) to be
written in the org buffer. So a typical org file after executing matlab
looks like

This is what the hack does and it does it nicely, the only problem is
that every time I execute the code matlab is started again, and for more
recent versions of matlab this can take some time. So the question is
whether the hack I used, could use the matlab-shell.
