Thanks Eric, that was nothing. The effort is yours alone.

BTW there is small and annoying differences between the sourceforge and
the github repository, in the sense that the graph is not the same, since
somebody committed some time ago a changeset to github which is not in
sourceforge, so I merged and synchronised but as I said the graph is not
entirely the same

Ok I will only have a change to test this in around 2 weeks.

BTW since you are in developer mode, there was something I was missing
recently. I try to look it up what is was.

As a former long term user of Xemacs, I hesitate to support is. In my
opinion, it should be left as it is if a certain feature cannot be
implemented for Xemacs so be it, but don't remove Xemacs compatibility code.

In comments I consider it as useful.

[Matlab-emacs-discuss] Support for "strings" in matlab/emacs mode + feature poll

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

Hi everyone,

Uwe recently merged in some updates for matlab-mode into the git master branch.   Thanks Uwe!

I'd like to encourage everyone to give it a try!  To get "string" to work, I had to start over on the indentation & font-lock support in 'char vector' and %comment as well as basic navigation with C-M-f and C-M-b.  A side effect is (paren), [array] and {cell} matching is much more robust, and we now support `show-paren-mode' and `blink-paren' modes instead of the old block highlighter.

All these changes means it would be great for folks to try it out and let me know if anything goes wrong!


And while I have your attention, I'd like to get some feedback about matlab mode.  We'd like to make some updates to the default values of some variables.  While I was in there, I'm thinking of also deleting support for ancient systems.  Here's a short list of things I was thinking could be changed and cleaned out:

* XEmacs support
* indent function body - always by default (no more question)
* functions have end - switch to t by default
* auto-fill - off by default, or maybe on only in comments
* matlab block highlighting - superseded by show-paren-mode.  Anyone w/ an ancient emacs need this?
* matlab-eei support - MATLAB stopped supporting this in the mid 2000.  Anyone still using this?
* matlab-complete-symbol & M-TAB binding - Anyone using this, or has everyone migrated to newer completion tools?  Which one?
* tempo templates ?


Does anyone have flags on any of the above?  Is there a new shiny emacs tool that should be supported instead of some old thing?  Please let me know!

Thanks
Eric

Re: [Matlab-emacs-discuss] Emacs hangs with a line

[Tak K. <tak...@gm...>]

I revered to matlab-mode-20180125.1810 from matlab-mode-20180928.1526 and
now it works.  I setup my Emacs in following manner.

(setq package-load-list '((matlab-mode "20180125.1810") all))

I also found that in an emergency case, following works.

(setq octave-comment-char ?%)
(add-to-list 'auto-mode-alist '("\\.m\\'" . octave-mode))

I use matlab.m for 10 years.  Thank you the maintenance.  I embed date
in a script using arrays and cell arrays.

Today I found that when buffer is with a line, emacs hangs.  Emacs

[Matlab-emacs-discuss] matlab shell and code folding

[Justin G. <jus...@gm...>]

Hey everybody,

I've just started using folding mode (folding.el) with matlab-mode. The
command matlab-shell-run-region filters out folds as comments. Is there an
easy method to unfold folds during the parsing section of
matlab-shell-run-region, to enable sending the fold contents to the
matlab-shell? I'll keep tinkering with in matlab.el but my lisp is quite
weak unfortunately.

Thanks,
Justin

[Matlab-emacs-discuss] collect command output without refreshing *MATLAB* buffer

[Thiago M. <tm...@gm...>]

I was having an issue with `matlab-shell-collect-commmand-output' not deleting
the output of emacsdocomplete (or any matlab command), leaving shell completion
broken. I found out it was happening because I had the variable
`comint-prompt-read-only' set to t.

While investigating that issue, I saw this comment in the function
`matlab-shell-collect-command-output':

> Ideally there would be some way to prevent the *MATLAB* buffer from refreshing
> as we are interacting with it, but I couldn't figure out a way to do that.

One potential way to prevent the buffer from refreshing is using the function
`comint-redirect-results-list'. So, the function mentioned above can be
implemented like this:


(defun matlab-shell-collect-command-output (command)
  "Send COMMAND to matlab process and silently capture output."
  (car (comint-redirect-results-list command "\\(?:.\\|\n\\)*" 0)))


As a bonus, no more issues with read-only prompts.

Thiago

[Matlab-emacs-discuss] run a cell in a script which contains a function

[Uwe B. <ou...@ma...>]

Hi the following script (not live script) can be executed in the matlab
editor, just on a cell
%% 
A = [4,-2,-1,-1; -2,6,-2,-3; -1,-2,5,-1;-1,-3,-1,6]
x = [0;0;1;0]
[lambda,v] = eigs_potencia(A)
%% 
function [lambda, v] = eigs_potencia(A)
    [n,m] = size(A);
    tol = 10^-6;
    itermax = 50;
    iter = 1;
    v = rand(n,1);
    v = v/norm(v);
    w = [zeros(n,1)];
    while (norm(v-w)>tol & norm(v+w)>tol)
        w = v;
        z = A*v;
        lambda = transpose(v)*z;
        v = z/norm(z);
        iter = iter+1;
        if iter > itermax
            warning('se ha alcanzado el numero maximo de iteraciones')
            break
        end
    end
    lambda, v, iter
end



However the command matlab-shell-run-cell seems not to recognize the
function which is defined in the very same file.

I think that is now an important feature to support, because matlab
supports is also in the live scripts.

Not sure how difficult that would be to implement. Any comments?

No it does not. I did not check this before thanks for pointing it out.
So the breakpoint is gone, since matlab is finished, but the icon stays.

I have to close and reopen the file. 

It gets worse. If I don't kill the Matlab process, close and reopen the
file, the icon is gone, but the breakpoint is still set.

Well so I think I will not include that function in matlab, it will be
too confusing. If I come up with a better more robust solution I will
reconsider it.

Sorry, I meant when the MATLAB process goes away, does GUD know to clean 
up the breakpoint icons along with the process.  It sounds like it is 
just with the commands which seems like a fine start.

Sorry for the delay. I am not sure I understand your question. 

Do you mean: when I run dbquit or dbclear from the command line, the
icons should disappear?

The answer to this is NO.

Function one, sets in Emacs a breakpoint and a icon
Function two, removes in Emacs the breakpoint and the icon.
And that works only in Emacs not in the matlab shell.


I could write a function, which would remove breakpoints and icons
region wise, or for the whole buffer, if that were necessary.

Re: [Matlab-emacs-discuss] correction

Hi Uwe,

I'm not very familiar with those APIs.  Do all the icons auto clean up 
when the GUD process goes away?


If so, it seems like a fine thing to include to me.

Right point taken. 

To defend myself: For ages I used Xemacs, whose matlab support was never
at pair with GNU emacs, so I used the matlab-shell debugging. When I
switched finally to GNU emacs, I could only enjoy the nice navigation
while debugging for a short while, since the Matlab API was dropped
basically a short while after I switched. (in 2011A or B, right?).

So I, again, switched to the debugging from the command line, which is
functional but not very convenient. Now thanks to Odd Andersen, Emacs
navigation, in bit simplified form, during debugging is back and I would
like to use Emacs and not the matlab-shell, so it simply did not occur
to me that people could run into the problem you mentioned. So you are
right: I should adapt the documentation accordingly.

So what do you say: shall I do that and provide a patch to the list, to
see what others say? (So far you are the only one who gave some
feedback.

Right, that sounds like a good idea. However till the end of May I will
be busy debugging a lot of students programs so I might not find the
time to do it. Any other takers?

Hi Uwe,

Looks like you were having some fun with the GUD API. :)

The type of snippets you forwarded look like they could work, though I 
didn't try them.  My assumption was that if users started using a 
feature like you describe, and and typed:

dbclear all

or

dbstop in foo

and icons didn't appear/disappear correctly then they would send bug 
reports.  As long as it's clear that you have to use the EMACS commands 
to set/remove breakpoints, then maybe that's ok.

If you're feeling adventurous, a matlab script in matlab-emacs/toolbox 
that uses 'dbstatus' and prints out a formatted list of breakpoints 
could be used to 'fix up' the breakpoint icons.  Shadows scripts for 
dbclear and dbstop that call said script could probably get something 
kindof hacky up and running for keeping icons up to date.  This would 
require some new output filter/parsing to get going.  Could be a fun 
project.

Enjoy
Eric

[Matlab-emacs-discuss] setting the icon, for a breakpoint, a total kludge

[Uwe B. <ou...@ma...>]

Hi 

The following code sort of works, it is not nice, comments are very
welcome

(require 'gdb-mi)
(setq default-text-properties '(foo 1111))

(defun my-gud-set-breakpoint-with-icon ()
  "Set Breakpoint and indicate on Editor"
  (interactive)
  (gud-break 1)
  (gdb-put-breakpoint-icon "false" (get-text-property 1 'foo)))

(defun my-gud-remove-breakpoint-with-icons ()
  (interactive)
  (gud-remove 1)
  (move-beginning-of-line 1)
  (mark-end-of-line 1)
  (gdb-remove-breakpoint-icons  (region-beginning) (region-end)))

[Matlab-emacs-discuss] correction

[Uwe B. <ou...@ma...>]

Last function should be



(defun my-gud-remove-breakpoint-with-icons ()
  (interactive)
  (gud-remove 1)
  (gdb-remove-breakpoint-icons  (line-beginning-position) (line-end-position)))

[Matlab-emacs-discuss] make gud-break visible

[Uwe B. <ou...@ma...>]

Hi 

I know that since a couple of years it is not possible for matlab.el to
follow the breakpoint during debugging. However thanks to Odd it is at
least possible to connect the debugger to the matlab source file which I
debug. 

Would it be possible when calling gud-break that the breakpoint is made
visible although it would not move during the debugging? I googled for
gud-break visible but cannot find anything.

Thanks and regards

Re: [Matlab-emacs-discuss] matlab-shell does not work (no such file or directory)

[N H. <hz...@gm...>]

Dear Vladimir Nikishkin,

Thanks a lot. You saved me.

I checked the exec-path variable inside Emacs, but there was no path for Matlab.
I added Matlab path to this variable manually using this:

(setq exec-path (append exec-path '("/Applications/MATLAB_R2018b.app/bin")))

and, finally matlab-shell works again. To install matlab-emacs should we add Matlab path to exec-path variable manually in the first place or should it be automatically added during installation? I remember that in my previous matlab-emacs installation, I did not change exec-path variable. This time, I installed the new Emacs using brew cask install emacs.

Anyway, thank you very much. I do really appreciate it.

Re: [Matlab-emacs-discuss] matlab-shell does not work (no such file or directory)

[N H. <hz...@gm...>]

Hi All,

I found the problem. It was silly of me. I should do “make” in the “~/path/to/matlab-emacs”. Matlab-mode is working now.
However, I have one problem with matlab-shell now. Whenever I want to run matlab inside emacs using matlab-shell, emacs could not find the directory of matlab as shown in the warning message:

"Searching for program: No such file or directory, matlab”.

I have surely added matlab to my PATH. I could run matlab -nodesktop in my terminal but I am wondering why matlab-shell does not work.
Before I had this matlab-emacs problem, I could also run matlab-shell inside emacs (previous version).

Could someone help me to resolve this? I am not quite familiar with unix commands and system.

Thank you.

[Matlab-emacs-discuss] matlab-load.el does not exist and matlab-cedet-setup error

[N H. <hz...@gm...>]

Hi All,

I am facing a problem with matlab-emacs. I have been using matlab-emacs for quite a while (used the old-verstion) and love it so much. Thank you very much for this awesome software, really appreciate it. Everything was fine when using matlab-emacs until yesterday.
Since yesterday I could not use matlab-mode and matlab-shell in my Emacs. I am not sure what the cause of this problem as I was configuring some parts of my .emacs file and also upgraded my emacs to the latest version. What can I think of is probably the Emacs upgrade is the cause.

I tried to install matlab-emacs from the both ways: via git clone and via melpa. Both did not work. Currently, I am using the git clone one. 
It seems that the “matlab-load.el” is not automatically generated. Once I executed (add-to-list 'load-path “~/user/.emacs.d/matlab-emacs”), the “matlab-load.el” does not exist in the matlab-emacs directory, and hence the command (load-library "matlab-load”) generates an error.

When I tried to execute another command: (matlab-cedet-setup), a warning says: srecode-map-entry-for-file is already defined as something else than a generic function. I do not really know what it means.

Does anyone have any hint/idea regarding this problem? I have tried to investigate the problem but could not fix it until now.

Thanks.

[Matlab-emacs-discuss] cd command tab-completion error on Windows (case-insensitive file system)

[Vladimir N. <loc...@gm...>]

Hello, everyone.

I found a slightly strange behaviour of matlab-shell on Windows.
I am not totally sure if it is matlab-mode's issue, or the
matlab-shell wrapper suggested at Emacs Wiki
(https://www.emacswiki.org/emacs/MatlabMode ,
https://github.com/mlt/matlabShell ) , but I thought I'd better
document it here.

So, suppose we opened the matlab shell:

On my Z:\ drive I have a catalogue called Temp (note the capital letter).
When I type in cd z:\t TAB, matlab-shell does its best to help me, and
proposes the following:
cd z:\tTemp

Note that instead of replacing t with Temp, it appended Temp to t.

I am not sure, but this seems like a bug.

Re: [Matlab-emacs-discuss] Building matlab-mode on Windows

[Vladimir N. <loc...@gm...>]

So, basically, I have installed matlab-mode from Melpa on a Linux
machine, and just copied the .emacs.d/elpa/ directory from it to a
Windows machine.
Am I risking something by doing like this?
The commands 'matlab-mode', 'matlab-shell' and 'matlab-cedet-setup'
have appeared, and at least matlab-shell appears to be working after I
have compiled and loaded the
matlab shell https://github.com/mlt/matlabShell

Not sure the setup is perfect though.
