classoffset in listings affect commentstyle

Question

Having trouble using listings package...

\lstset{
otherkeywords={0,1,2,3,4,5,6,7,8,9,(,),[,],:},
morekeywords={0,1,2,3,4,5,6,7,8,9,(,),[,],:},
classoffset=0, keywordstyle=\color{violet}, deletekeywords={0,1,2,3,4,5,6,7,8,9,(,),[,],:,function,endfunction,length,deff,zeros,sqrt,xtitle,cos,sin,intg,abs},
classoffset=1, keywordstyle=\color{brown!75}, morekeywords={0,1,2,3,4,5,6,7,8,9},
classoffset=2, keywordstyle=\color{blue!50}, morekeywords={(,),[,]},
classoffset=3, keywordstyle=\color{orange!50!yellow}, morekeywords={:},
classoffset=4, keywordstyle=\color{red!80!black}, morekeywords={function,endfunction},
classoffset=5, keywordstyle=\color{blue!40!cyan}, morekeywords={length,deff,zeros,sqrt,xtitle,cos,sin,intg,abs},
classoffset=0,
}

But the problem is in comments. When I put:

commentstyle=\color{green!30!gray},

my comments aren't green but each number becomes purple.

How can I force the comments to ignore classoffset styles?

To get there that was quite hard but I've not a single clue to continue to modify the color...

If someone can help me that's wonderful!

Answer 1

So after reading Colored strings by listings package and Problem with literate and breaklines=true in listings package I can somehow fix the problem.

Since fontspec is used, You need to run this code with XeLaTeX and LuaLaTeX. The reason is that literate=* is broken by your accent characters; and also, if you are going to use a lot of them, using a unicode compiler will make your life easier.
