  • I want to change the font color in a listing.
  • I want only several lines in the listing to change its color (e.g. 1, 2, 9, 10, 12, 13). That is, I want to apply the color to individual lines of the listing.
  • I want the line number that match the colored lines to be colored as well (e.g. 1, 2, 9, 10, 12, 13).
  • I want the color to be expressed in HTML (hexadecimal) format.
  • I am including the listing's content from a separate file.

How can I accomplish this?

This is my snippet (the included listing is now local for demonstration purposes):

\documentclass{article}

\usepackage{listings}

\usepackage{xcolor}

\definecolor{custom_grey}{HTML}{818181}

\lstdefinestyle{base}{
  moredelim=**[is][\color{custom_grey}]{@}{@},
}

\renewcommand\thelstnumber{%
  \ifnum\value{lstnumber}=10
  \else
    \ifnum\value{lstnumber}>10
      \the\numexpr\value{lstnumber} + 5\relax%
    \else
      \arabic{lstnumber}%
    \fi
  \fi
}

\begin{document}

\begin{lstlisting}[numbers = left, style=base]
@#First comment@
@...@
'YY-MM-DD HH:MM:SS.sss'
|Code line|
--------------------------------------------------------
========================================================
|Code :: line|
========================================================
@#Additional comment@
@...@
'YY-MM-DD HH:MM:SS.sss'
@#End comment@
@...@
\end{lstlisting}

\end{document}

  • When changing the lstlisting environment into a \lstinputlisting call, the code is formatted correctly for me (also with the red highlight). Could you be more clear about what exactly fails for you? Also, the syntax for RGB and HTML color schemes is defined in the xcolor manual.

\lstdefinestyle{base}{
  moredelim=**[is][\color{custom_grey}]{@}{@},
}

\renewcommand\thelstnumber{%
  \ifnum\value{lstnumber}=1
{     \color{custom_grey}\arabic{lstnumber}}%
\else
  \ifnum\value{lstnumber}=9
{     \color{custom_grey}\arabic{lstnumber}}%
\else
  \ifnum\value{lstnumber}=12
{     \color{custom_grey}\arabic{lstnumber}}%
\else
\arabic{lstnumber}%
  \fi\fi\fi
}

\begin{document}

\begin{lstlisting}[numbers = left,
style=base]
@#First comment@

@#End comment@
@...@
\end{lstlisting}

\end{document}
