matlab source code syntax highlighting about code-prettify HOT 27 CLOSED

Do you know where I can find a matlab grammar?  A quick search doesn't turn one 
up,
and I don't know enough about it to track down a similar language's grammar 
either.

ViewVC supports matlab with the help from Highlight
(http://www.andre-simon.de/doku/highlight/en/highlight_langs.html). I attached 
the
definition file from Highlight project. Hope this helps.

An additional complication is that Matlab and Objective-C files share the same 
file 
extension (.m).

note that octave uses the same syntax
http://www.gnu.org/software/octave/

some vim/emacs modes for matlab/octave:

It looks quite bad now:

GLImageProcessing/BitsPlusPlus.m?spec=svn1789&r=1789

There are even more matlab supporting highlighters available. Geshi has one and 
WebSVN:
http://svn.berlios.de/wsvn/osxptb/beta/Psychtoolbox/PsychGLImageProcessing/BitsP
lusPlus.m?view=markup

There are other 

Is anyone still working on this? Can I get involved and help develop this 
highlighting scheme?

I'm not working on matlab because I don't have a grammar to work on.  People 
keep pointing me at VIM modes and the like but unless those are public domain 
or use the same license as this project, I can't look at them.

Thanks. I'll try to compile a good document or some code for you.

Hi,

If I understand correctly, the BSD license is compatible with the Apache 
License.
If so, maybe Pygment (written in Python) might be of some use: BSD licensed 
(http://pygments.org/faq/#what-is-it), with a matlab lexer 
(https://bitbucket.org/birkenfeld/pygments-main/src/071002c113cb/pygments/lexers
/math.py#cl-95)

HTH

Now that Berlios is closing shop, it would be cool if we got Matlab 
highlighting on Google Code. 

I proposed to move over to GC, but this one niggle remains:
http://code.google.com/p/psychtoolbox-test/source/browse/beta/Psychtoolbox/Updat
ePsychtoolbox.m

Sorry I've been unresponsive.  Can you expand on what is wrong with the 
formatting of UpdatePsychtoolbox.m ?  I don't know matlab syntax well enough.  
Is it that % comments aren't recognized as such?

It’s all wrong. I assume that is because Objective C is used (also .m).

I posted links further up to other services who highlight it up correctly.
Basically any highlighter you can find does Matlab/Octave.

We have migrated now: http://psychtoolbox-3.googlecode.com

What kind of help do you need, Mike? Do you want a full patch, or do you want 
to do it yourself and just need hints?

Matlab syntax is not so complicated, it just needs the proper keywords and 
markers. I don't know how many keywords of the standard library you want to 
include.

I am happy to accept a patch, or if you can point me to a lexical grammar I can 
do it.  I don't know quite what to do about file name collisions.  What google 
code chooses to load is up to them, but I can talk to them and maybe they can 
load the matlab version for projects that have a certain tag.

I’m not sure what consitutes a lexical grammar. Is that something you can 
glean from other syntax highlighters or is it a formal definition in a defined 
format?

If I would do it I would just proceed by eye.

Your tag idea is a very sensible one.

here you go- flex and bison files from octave (GPL matlab clone)

http://hg.savannah.gnu.org/hgweb/octave/file/tip/src/lex.ll
http://hg.savannah.gnu.org/hgweb/octave/file/tip/src/oct-parse.yy

gtksourceview's highlighter, also GPL:
http://git.gnome.org/browse/gtksourceview/tree/data/language-specs/matlab.lang

mike, can you let us know if there is any issue as far as licensing or format 
for the examples we've provided?

Yes.  The GPL is incompatible with the Apache 2 license.  If I were to read GPL 
code, translate it into another language and put an Apache 2 license on it, I 
would be violating the license.

what about BSD?  github uses pygments...

Here is my implementation of MATLAB syntax highlighting for 
google-code-prettify (released under MIT license):
https://github.com/amroamroamro/prettify-matlab

Specifically:
https://github.com/amroamroamro/prettify-matlab/blob/master/js/lang-matlab.js

Sweet!!!

Great.  I see a testcase in 
https://github.com/amroamroamro/prettify-matlab/blob/master/demo/index.html .  
I'll integrate that patch.

[deleted comment]

Yes, you can see its failing on some edge cases (nested comments)..

I had modified version in a separate branch that does not try to detect MATLAB 
functions:
https://github.com/amroamroamro/prettify-matlab/blob/no_functions/js/lang-matlab
.js

This is mainly to keep file size to a minimum, as there are more than 1000 
functions in core MATLAB alone:
http://www.mathworks.com/help/matlab/functionlist-alpha.html

The version from earlier is now available in release branch 4-Mar-2013, the 
download list, and via the autoloader.  amro^3, would you like contributor 
access so you can maintain lang-matlab.js here?

Great. I'm happy to maintain lang-matlab.js
