Is it possible to add support for MATLAB

[zhiboz]

MATLAB is gaining its popularity among engineering professionals and students; Its creator, MathWorks, claims that it has over 2 million users worldwide. Is it possible for you to add support for MATLAB please? Thanks very much!

Sorry for the late reply, I totally missed the notification.

If Scintilla supports it and someone provides the keywords I could add it I guess. Although I don't use MATLAB at all so I need some good code samples to check if everything works.

You can't attach anything on GitHub. So use the webform and upload the files somewhere easily accessible.

You may get a copy from http://www.mathworks.com/matlabcentral/fileexchange/8550 . Thanks!

Please try this build and let me know.

Keep in mind that I don't use Matlab myself so there might be things that should be different. The code changes are in the Matlab branch here.

Also the lexer itself which comes from Scintilla seem a little limited, for example it doesn't highlight block comments properly when I use %{...%}, but from what I read this should be supported.

[XhmikosR]

I cannot do that because .m files are associated to open with the C/C++ lexer. I'm pretty sure there is another way to solve this apart from removing .m files from the C/C++ filelist, but unfortunately I have no idea how to do this at this point.

[XhmikosR]

I didn't mean supported in Scintilla, since I know it's not... I mean that in general %{...%} is a block comment in Matlab.

Anyway, not sure what I'm going to do with this patch since like I said above m files are associated with the C/C++ lexer.

[XhmikosR]

The matlab branch is up to date, but I still don't know if I should merge this.

If anyone is interested to work on this, they are more than welcome to do so.

[XhmikosR]

Block comments are properly detected now with the updated Scintilla.

Great news, very much appreciated! Any plan to merge this into the master branch?

[XhmikosR]

I cannot solve the issue with .m files. Please leave this ticket open until the patch is merged.

Another thing I noticed.

M = regexp(str, {'(?-i)\w{5}(?=CASE)', ...
                 '(?i)\w{5}(?=CASE)'}, 'match');

M{:}
ans =
    'UPPER'
ans =
    'UPPER'    'lower'
    break

If I comment out

M = regexp(str, {'(?-i)\w{5}(?=CASE)', ...
                 '(?i)\w{5}(?=CASE)'}, 'match');

M{:}
%{ans =
    'UPPER'%}
ans =
    'UPPER'    'lower'
    break

It shows as if it's commented out until the end. But this is a Scintilla issue.

MATLAB editor handles it this way too. It works if you put %} into a separate line as below.

M{:}
%{
ans =
'UPPER'
%}
ans =
'UPPER' 'lower'
break
