matlab source code syntax highlighting

[GoogleCodeExporter]

Quite important I think. And it is provided by sourceforge.net. Would you
consider adding it?

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

It looks quite bad now:

There are even more matlab supporting highlighters available. Geshi has one and

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)

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:

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?

Original comment by mikesamuel@gmail.com on 10 Oct 2011 at 9:39

[GoogleCodeExporter]

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.

[GoogleCodeExporter]

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)

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?

Original comment by erik.fli...@gmail.com on 27 Mar 2012 at 1:12

[GoogleCodeExporter]

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:

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

[GoogleCodeExporter]

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:

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?

[GoogleCodeExporter]

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