Cg Code in Latex

Question

I am writing some document which contains Cg (C for Graphics) code in the document. I want to show the code in a neat highlighted mode. Any easy method to suggest? I tried the listings package but it doesn't support Cg language.

Answer 1

OK, I found the solution to my own question. I defined the Cg language using the following code:

\lstdefinelanguage{cg}{
    morekeywords={void, float, float2, float4, float4,
        float4x4, POSITION, TEXCOORD0, out, uniform},
    morecomment=[l]{//}
}

Some notes:
1. The 'morekeywords' specify the keywords of the language. Obviously, there are many more keywords in the Cg language, but I used the ones I need.
2. The 'morecomment' is used to specify commenting styles in the language. Cg language use the same style as C language.

Then I used the following code to make some customization:

\lstset{
    language=cg,
    tabsize=2,
    basicstyle=\ttfamily\scriptsize,
    keywordstyle=\color{blue},
    commentstyle=\color{green}\scriptsize,
    stringstyle=\color{green},
    showstringspaces=false,
    breaklines=true
}

Finally, including my code in the document:

\lstinputlisting[language=cg]{VertexProgram.cg}

Don't forget to include the listings package:

\usepackage{listings}

Hope that helps!
