Re: [Matlab-emacs-discuss] Matlab-Shell & Sun Grid Engine

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

Hi Eric,

 

Many thanks for your swift reply !!

In fact I've just realised things are more complicated than that. Eventually
I did manage to submit matlab as a Sun Grid Engine job, but then, the
communication between emacs and matlab is broken because the two processes
do not necessarily run on the same machine.. So it looks like the only way
is to submit emacs as a job first, and start matlab normally from there (on
the same machine !).

 

On a slightly different note, I've been using EmacsLink for years, but only
now am I starting to look at matlab-emacs. Undoubtedly there are a few
things I need to learn and to get used to, but one thing that I miss
terribly is the ability to "see" where my breakpoints are in the source
code, pretty much in the same way as mlint warnings are reported (with
linemark.el).

 

Is this feature not supported ? Or is something broken in my configuration ?

 

Cheers,

David.

Hi,

 

  The variable 'matlab-shell-command' needs to be a string that represents a
single executable.  In your case, you want it to just be "qrsh".   You would
then set 'matlab-shell-command-switches' to be '("-b" "y" "-q" "single" "-V"
.) with all your switches spelled out.  It seems outlook is messing with my
'quote' marks, so you will need to type it in and not copy what I typed
here.

 

Good Luck

Eric

Hi everyone,

 

I'm having a simple problem configuring matlab-shell-command.

The thing is I actually never run matlab locally on the machine I am logged
on, but matlab is submitted as a job to a large pool of linux machines with
the Sun Grid Engine.

 

In other words, I don't use the "matlab" command at the shell prompt, but
instead I use something like:

 

qrsh -b y -q single -V -cwd -noshell matlab

 

Now, everything works fine by default, if I set matlab-shell-command to
"matlab".

But if I set matlab-shell-command to "qrsh -b y -q single -V -cwd -noshell
matlab", a problem occurs in matlab.el (matlab-shell function), and more
specifically on this line :

 

(switch-to-buffer

      (apply 'make-comint matlab-shell-buffer-name matlab-shell-command

                           nil matlab-shell-command-switches))

 

which returns the error message

Searching for program: no such file or directory, qrsh -b y -q single -V
-cwd -noshell matlab

 

As a workaround, I have tried defining an alias in my .cshrc, something
like:

alias sge_matlab 'qrsh -b y -q single -V -cwd -noshell matlab'

 

and this works to manually start matlab from the shell. But again if I set
matlab-shell-command to "sge_matlab", then I get

apply: Searching for program: no such file or directory, sge_matlab

 

So what is the proper way to get everything to work in my case ?

 

Many thanks in advance !

Cheers,

David.

Hi,

Good Luck getting your matlab shell working.  It sounds like a tricky environment.

EmacsLink depended on some Java APIs that aren't available any more.  Most of what you may think of as EmacsLink, however, is the same as matlab-emacs except that matlab-emacs on SourceForge has a bunch of misc bug fixes.  The matlab-shell command was an EmacsLink predecessor, and fortunately, still works.

The breakpoint feature was one of the things not available.  I would be possible to fake it out by reading commands that set breakpoints, and using linemark to remember them, but I imagine that would be quite tricky.  It would probably work to have some command for matlab-shell that calls dbstatus, reads the breakpoints, and dumps out a lisp struct that could be read in to populate a linemark database.  I picture a couple pages of code for that.  You'd have to run the command to show the BP though.

If someone would like to give it a try, I'll be happy to give some pointers.
Eric

[Matlab-emacs-discuss] Problem defining include paths?

[Matthieu L. <mat...@ho...>]

Hello,

I am trying to get semantic to work with my Matlab projects. I have the following defined in semanticdb-matlab.el:

(defvar semanticdb-matlab-include-paths
      '("/home1/m/matthieu/projects/"))


When I open a Matlab file under my "projects" in emacs, semanticdb spends some time "Searching for user files" (about 30 seconds). Then I select a function call that is defined somewhere else under "projects" and execute "semantic-ia-fast-jump". It fails with the message "Could not find suitable jump point for [my function name]". However, *after* opening the file where the function is defined, the jump works.

I guess the semanticdb indexing function is not working for me, but I don't know what I am missing. Does the indexing work recursively? Is semanticdb-matlab-include-paths the right variable to use? (I recompiled all emacs-matlab files after adding my project directory and it still doesn't work).

Thank you for your help,
Matthieu
 		 	   		  

Re: [Matlab-emacs-discuss] Bug report (patch): matlab.el: previous command at shell prompt fix

[Mark H. <mh...@gm...>]

Thanks for the reply.

I've been testing this over the past few weeks, and the issue still pops up sporadically for me, so you should not include the patch below.

I think it may be related to using Aquamacs on Mac OS X.  
I've switched to using a more stock Emacs: 23.3 from http://emacsformacosx.com/builds.
So far I haven't seen it, but if recurs I will look into it and let you know.
Aquamacs seems to have multiple issues with matlab-shell, for anyone else that was thinking of using it.

Best,
Mark

Re: [Matlab-emacs-discuss] Cedet integration

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

Hi,

I was not able to reproduce this issue (I don't have a mac handy).  Your emacs should have CEDET built in, so perhaps it is related to built-in CEDET not being overridden by cedet 1.0 which you installed separately?  I never tried CEDET from Emacs 23.3 and matlab together, I've always used CEDET installed from CVS or, more recently, BZR.

If you have the CEDET setup from the instructions that came with the cedet 1.0 tar ball you should be ok.

Re: [Matlab-emacs-discuss] Fwd: how to see mlint error messages..

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

Hi,

Sorry for the very slow reply.

Supposedly, if you say 'yes' to configure your mlint, you can point that variable at your mlint programs.  This is a list of places where mlint might be.  If you set it to some places for mlint, it will attempt to find them either on your path, or in a MATLAB install area.  If in the custom buffer you save for a future session, you should be ok.

If it comes back at you a few times, just add mlint to your path before Emacs starts, and that will definitely fix it.

[Matlab-emacs-discuss] Possible bug in matlab-shell-run-region when region contains fprintf and sprintf formatting characters

[Graham T. <ess...@ho...>]

Hello,I'm having problems when executing a region with C-c C-r (matlab-shell-run-region) when the region contains a line like:
fprintf('My number is %d\n",4);
This also happens with sprintf lines. It seems that matlab-emacs interprets everything after the % as a comment, and so only the first part of the line is executed.
I'm not an emacs lisp hacker at all. Does anyone have a solution?

Re: [Matlab-emacs-discuss] fprintf/disp output to another emacs buffer ?

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

Hi,

When you start MATLAB in the matlab-shell in Emacs, it causes Matlab to run 'emacsinit'.  In Emacs init, it sets up emacsclient as the default editor.  If your Emacs uses 'server-start' the, typing 'edit' in Matlab will cause the file to open in Emacs.

Dear all,

Based on the previous exchange of emails with Eric, I would like now to standardize a bit this ability to redirect fprintf output to a shell.

In particular, I'd like to design the equivalent of a figure in matlab but for text, let's call it a "message box", so that text messages are sent to it.

More clearly, I'd like to achieve something like

%% Opening a new buffer in emacs with a shell running inside  >> open_msg_box

%% get the current message box opened (a label to it)  >> gc_msg_box ans = 'ttys0'

%% print a message from matlab to this shell  >> message("Hello World");


Here is my related question:

Do you know if there is a way (e.g. with emacsclient) to open a new emacs buffer from matlab (running inside emacs in matlab-shell) and to run something inside (like "shell") ?

Best,
Laurent

Re: [Matlab-emacs-discuss] Insert break-points using matlab-emacs

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

Hi,

You can  set breakpoints, and step over code a line at a time.  This is all done via GUD interface in Emacs (Grand Unified Debugger).

The GUD menu is enabled in matlab files when you hit a break point.  The keybinding is

C-x C-a b

but if it doesn't get set, you can always do:

M-x gud-break RET

on some line of code.

In MATLAB Shell, you can do next/step with C-x C-n and C-x C-s.  From the source file, the prefix is C-x C-a.

This is the standard GUD interface for debuggers.

Today I founded my latest Matlab resisting showing the arrow during debugging every time.  It may be the process filters in Emacs need to be updated with recent changes.

Re: [Matlab-emacs-discuss] fprintf/disp output to another emacs buffer ?

[Laurent J. <lau...@uc...>]

This works great! Thanks Eric.

Under Mac OS, once a terminal is open through emacs or not (say in 
/dev/ttys001)
I can do now, inside a matlab script,

fid=fopen('/dev/ttys001','w');
fprintf(fid,'hello world\n');

and this message is truly printed in this terminal!
This is nothing but the stdout redirection I was looking for.

Best,

Re: [Matlab-emacs-discuss] fprintf/disp output to another emacs buffer ?

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

I used to do this back in 1996 or so, and it worked like this:

Use:
M-x shell RET

to create a shell, or create a shell with a name by using C-u prefix to the shell command.

In the shell, you can find out which terminal it used.  Sometimes it is an environment variable.  I found I can use the 'tty' command on my linux box today.

You can fopen that file name and write to it as long as permissions are set ok.

I tried this in my emacs today with

echo "moose" >> /dev/pts/4

and that worked to get to my other shell window.

Good Luck
Eric

Re: [Matlab-emacs-discuss] Matlab-shell tab complete

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

Hi,

Sorry for the delay in answering.

I looked in the code, and directory-tracker is on, and the TAB key is bound to  matlab-shell-tab which starts with completing file names.

HOWEVER, it only does that if matlab-shell-ask-MATLAB-for-completions is turned off.

Why MATLAB can't complete your filenames, I don't know, unless you are expecting something MATLAB can't do itself which Emacs used to do before that variable was turned on.

You could go to matlab-shell-tab and just disable the if statement before completing file names to something you prefer.
