# Alternate text style for odd and even line

I want to make someting like the lstlinebgrd package to creating a zebra effect.

\documentclass{article}
\usepackage{lstlinebgrd}
\usepackage[english]{babel}%If not an error occurs
\begin{document}
\begin{lstlisting}[language=C,basicstyle=\ttfamily,linebackgroundcolor={\ifodd\value{lstnumber}\color{green}\fi}]
First line
Second line
Third line
Fourth line
\end{lstlisting}


but alternate text style for odd and even line, like this non-working code: note the basicstyle={\ifodd\value{lstnumber}\it\fi}

\documentclass{article}
\usepackage{lstlinebgrd}
\usepackage[english]{babel}%If not an error occurs
\begin{document}
\begin{lstlisting}[language=C,basicstyle={\ifodd\value{lstnumber}\it\fi},linebackgroundcolor={\ifodd\value{lstnumber}\color{green}\fi}]
First line : normalfont
Second line : italic
Third line : normal font
Fourth line : italic
\end{lstlisting}


I have tried to modify the code from : Creating a zebra effect using listings (who led to the package lstlinebgrd) without succes.

I know the listing package, nor the package lstlinebgrd are conceive for that. My latexfuu is not enough to hack a solution. Maybe you can help me, or give me a direction? An other package maybe. The solution don't have to be for code but for text.

Rather then use of basicstyle which will be applied on all listing code you can modify identifierstyle, commentstyle, stringstyle, keywordstyle like this

\documentclass{article}
\usepackage{lstlinebgrd}
\usepackage[english]{babel}%If not an error occurs

\def\oddtest{\ifodd\value{lstnumber}\normalfont\else\itshape\fi}

\begin{document}
\begin{lstlisting}[language=C,
identifierstyle=\oddtest,
stringstyle=\oddtest,
keywordstyle=\oddtest,
linebackgroundcolor={\ifodd\value{lstnumber}\color{green}\fi}]
First line : normalfont     % comment
Second line : italic        % comment
Third line : normal font
Fourth line : italic
\end{lstlisting}
\end{document}
