Hello,

I'm currently writing an article where most results were computed with a Pari/GP script. I would like to include it in the methods section, and tried the 'listings' package to do so. Unfortunately, this package does not properly handle Pari comments (\\ seems to be a nightmare for LaTeX).

I even tired to define Pari as a new language, with :

\lstdefinelanguage{parigp}
{    morekeywords={for,if,sum,binomial,my,eval,print,return,vector,write},%
    sensitive=true,%
    morecomment=[l]{//},%
    morecomment=[s]{/*}{*/},%
    literate={//}{\textbackslash\textbackslash}{2},
}

but to no avail...

 

     This might do the trick:

{
    \catcode`\#=0
    \catcode`\\=11
    #lstdefinelanguage{parigp}
    {    morekeywords={for,if,sum,binomial,my,eval,print,return,vector,write},%
        sensitive=true,%
        morecomment=[l]{\\},%
        morecomment=[s]{/*}{*/},%
    }
}

   but I advise against italic for comments (the italic backslashes are really ugly).

        Hope this helps,
