[Matlab-emacs-discuss] Finding errors cited in the shell buffer

[Torben K. <tk...@es...>]

I still have some problems getting matlab-shell-last-error to work every time.  As a work around for me I did the below. Maybee others can use that. However, I have no idea how general the solution is.

(defun tk-goto-matlab-error ()
  "Goto last matlab error above"
  (interactive)
  (search-backward "error")
  (matlab-shell-html-go))

and then prehaps

(global-set-key "\C-ce" 'tk-goto-matlab-error)

or something more smart.

Re: [Matlab-emacs-discuss] tab completion of matlab shell mode for R2014b

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

Hi,

This came up a bit earlier on this mailing list.  I have a first pass fix but am waiting on help from the team who changed the API on how to do it right without breaking things for older MATLABs.   I'll post when I've updated CVS.

Thanks
Eric

Subject: [Matlab-emacs-discuss] tab completion of matlab shell mode for R2014b

Hello.

I have been using matlab shell mode with GNU emacs for a long time by now.
I recently upgraded MATLAB from R2014a to R2014b.
Then, somehow, the tab completion (i.e., automatically complete the full filename by giving a few starting characters of that filename followed by pushing the tab key) is not working anymore.  I have been using matlab.el version 3.3.1, and my machine is Macbook Air under OS X Mavericks.

I got the following error shown in the minibuffer of emacs:
matlab-shell-tab: Args out of range: "No method 'mtFindAllTabCompletions' with matching signature found for class 'com.mathworks.jmi.MatlabMCR'.
 
", 2251, 109

I would greatly appreciate it if you could help me fix this problem since the tab completion is a really useful feature and I want to keep using it.

Thanks,
Naoki

Emne: RE: Problem/bug matlab emacs mode ?

Hi Torben,

I tried reproducing the hang you implied, but I could not.  Maybe there are multiple lines from your script needed?

A good way to see what is going on is to use:

M-x toggle-debug-on-quite RET

and then repro the hang, and press C-g.

Re-toggle to disable since it is very annoying to leave on.

That stack will point at what the problem area is, and possible what additional data is needed to reproduce.

Thanks
Eric

Re: [Matlab-emacs-discuss] Bug in auto-filling strings

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

Hoo boy.   That’s a hairy one.   The code for navigating over a string is good, and over if/end type constructs and [arrays of symbols] is all good, but I don’t have anything for concatenated strings yet.   The current code for skipping a sexp gets confused if there are [] in the string being skipped inside the brackets.

I’m sure it could be brute-forced with enough time, but it’ll be messy.  ;)

Hi Eric,
That fixed some of the errors, but I can still find bugs.  For example, take the m-file:
foo = 'correct';
disp(['this is a ', foo, 'string']);
Put your cursor at the end of the 2nd line, change fill column to 18, and put a space.  Mine results in:
foo = 'correct';
disp(['this is ' ...
      'a '], foo, 'string']);
which has an extra ] and is a syntax error.
This is definitely not an urgent issue, so take your time.  Let me know what else I can do to help!  I really appreciate your code, and enjoy contributing to good free software.

Subject: [Matlab-emacs-discuss] Bug in auto-filling strings

Hello developers,

This is a bug report for matlab-mode (I hope this is the right place to submit these?)
I'm using version 3.3.2
When I'm editing a file in MATLAB mode, I found a bug in how the auto-fill works, an example is below.
0) open some m-file in matlab mode
1) set your fill column to 40 (c-x f 40)
2) create the line: "disp(['this is a , foo, ' string']);"
3) change fill column to 32 (c-x f 32)
4) put a space after the line, causing it to auto fill.  Mine now reads:
disp(['This is a ', foo, [' ' ...
                    'string']);

The bug is that there are now two opening "[" but only one closing "]" and this is a syntax error.
I can produce other similarly syntax errors auto-filling with different fill-columns, so something is buggy in how the auto-fill is working.

I like MATLAB mode a lot, thank you for great software!

Re: [Matlab-emacs-discuss] no link within the error message

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

Hi Sebastian,

Newer MATLABs have different text output for errors than in the past.  If you get the latest Matlab.el from source-forge, (as of last week when someone else reported it) and look in matlab.el for the variable gud-matlab-error-regexp, you will see where I have an if'd out regex that should work for some of the new error messages.   I hadn't quite worked out how to have one regexp for all MATLABs yet so I hadn't enabled it.

If you update this expression so it works better, let me know and I can merge in your patch.

Re: [Matlab-emacs-discuss] Auto-completion while using Matlab remotely

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

Hi,

The reason is that the Semantic part tries to find the actual .m files so it can build up its symbol tables.

In theory, you could use TRAMP and rig up a directory name by hand (ie - not using the code in the defvar for line 55), such as:

(setq semantic-matlab-root-directory "/ssh:william@remotemachine/usr/local/MATLAB/whatever")
(require 'matlab)
(require 'semantic-matlab)

and you might be good to go.   I've never tried it though, so you will probably need to do some tweaks in semantic-matlab.el to round off the corners.

If you figure out how to do this, and/or if semantic-matlab.el needs patching that you create, let me know and I'll apply your patches / doc updates.

Good Luck
Eric

but I'm new to lisp and I'm not getting anywhere with this. Any ideas?
 		 	   		  

[Matlab-emacs-discuss] Adaptive comment column for 'matlab-comment', i.e. like 'comment-dwim' in Emacs?

[Christian R. <chr...@gm...>]

Hi,

Is it possible to make 'matlab-comment' behave more like 'comment-dwim' in
the mode 'Emacs-Lisp'?

What I'd like is the following behaviour. When you use 'M-;'
(matlab-comment) and there is already a comment on the line that is too
long, i.e. extends beyond 'fill-column' (76), then the '%' is shifted to
the left if possible in order to keep the comment within the 'fill-column'.

Note: I tried calling 'comment-dwim' in matlab-mode, but it places the '% '
at the wrong place and the right alignment isn't working properly. I.e. the
'% ' is moved as far left as possible, not merely as much that is needed to
make the comment fit.

Best regards,
Christian

PS. In case the above isn't clear, here's an example.
Let's say we have this line of code:

x = 1;

Pressing 'M-;' will add '% ' at column 40. Then we add a long comment,
getting this:

x = 1; % Here is a comment that is getting long

Now press 'M-;' again, and now the '%' is shifted to the left, resulting in
e.g.:

x = 1; % Here is a comment that is getting long

Re: [Matlab-emacs-discuss] Tab-completion (auto-complete) in matlab-mode, not in M-shell

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

Hi Nor,

The MATLAB path is the current directory, or whatever is in your current MATLAB Path.  Only MATLAB knows what that is, though you could rig something up to mimic that all in Emacs.

Since the current working directory is on the path, if you want to pull completions from a MATLAB process, you need to CD matlab to that location, and probably CD back when you are done getting completions.  That hasn’t been implemented.  There is also just pulling completions for use by autocomplete.  Right now getting those completions is only implemented in the TAB keybinding for matlab shell.   Someone would need to refactor the matlab-shell code to make a handy utility.

As far as setting up an ac-sources, I’m not sure what that means.  If you wanted to make a variable full of all the paths on MATLAB’s path by default, that is certainly a straightforward thing to do.   It is easy to ask MATLAB for its current path.   I just don’t know enough about autocomplete to help make that happen.

Hi Eric,

Thanks for your quick reply. I guess what you mean is that there is no "matlab-sources" that can be added to ac-sources so as I can get aoutocomplete suggestions in matlab-mode, right?

I am looking for competitions in matlab-mode. I would like to get the same behavior of M-shell in matlab-mode. When I type "ff" and I hit TAB twice in M-shell I get a competition list suggestion with "fft fft2 etc". However, when I type "ff" and hit TAB while editing an .m file in matlab-mode, I don't get any suggestion. Is there anyway to get competition suggestions in matlab-mode when editing an .m file or this feature is not implemented?

A way around would be to use autocomplete. Is there any matlab-source to be added to ac-sources to get autocompletition or this is what you say nobody has written a backend for this?

Using the right emacs terms is a little bit hard since I am a beginner :)

Thanks a lot!

Nor

Hi Norberto,

There is OK CEDET support for MATLAB on the sourceforge site, but it isn’t very broad.  As such, you should be able to setup autocomplete and CEDET for MATLAB the same as C or some of the other supported languages.  If you also want MATLAB shell based completions, no one has tried to link those two things together.

To use auto-complete with M-shell, someone would need to write an auto-complete backend that just calls to the same routine that TAB in M-shell uses.   I’ve never created a backend for that, but on the MATLAB shell side you can use ` matlab-shell-completion-list’ to get completions from a string, or copy out chunks of ` matlab-shell-tab’ to get the current text from the shell buffer.

Subject: [Matlab-emacs-discuss] Tab-completion (auto-complete) in matlab-mode, not in M-shell

Hi all,

I'm new to the use of matlab+emacs. I've configured my .emacs so as I'm able to get tab competition in M-shell. However, I'd like to have auto-complete to work together with cedet semantic to get competition suggestions when editing my .m files in matlab-mode (not in M-shell mode).

How do I tell autocomplete to use Matlab sources? Is this possible?

Also, I would like to keep the default mode of auto-completition in M-shell. That is, a pop-up window and a yellow win help information instead of having a separate mini-buffer when hitting twice tab. Any ideas/suggestions?

Thanks!

Re: [Matlab-emacs-discuss] emacs hangs after a return when editing mfile

[Sina T. <sin...@gm...>]

Hey Larrabee,

You can use the emacs profiler to find the bottleneck. M-x profiler-start,
'enter' to accept the default cpu profiling option, then reproduce your
problem, C-c out of it, and M-x profiler-report.

Hope that helps!

[Matlab-emacs-discuss] emacs hangs after a return when editing mfile

[L. L. S. <ls...@gm...>]

Hi,

I have had this problem for a long long time, just lived with it.

Thought I would try to ask for any solution.

I am in emacs, in matlab-mode, editing an mfile.

There are only comment lines above the cursor (with a single "%  " at beginning of line).

I hit return, and emacs hangs for a long time, but a few C-c will finally give me back control.

I have non problems down in the file once I am "away" from the initial comment lines.

Very very very reproducible.

Version 3.3.2

Thanks, Larrabee

Hi Hunter,

Thanks a lot for your response. Luckily, I managed to fix it yesterday. I downloaded and installed all files once more (in a different way than the first time). I followed the instructions here: http://stackoverflow.com/questions/2376178/matlab-script-editing

So now it finally works :-)

Thanks,
Helene

Have you opened matlab via emacs (using 'matlab-shell') successfully, and are typing 'edit myfile.m' into the matlab command line?  Or something different?
