[Tex/LaTex] way to enable syntax highlighting coloring in Lyx for program listings

codecolorlistingslyxsyntax

I want to embed a small program listing and have used Insert -> Program Listing in LyX's menu for that.

The settings dialog supports selecting a language (Java), but I can't actually see any difference.

Is there a way to get real syntax highlighting/coloring?

Lyx's "Insert -> Program Listing" is internally based on the listings package, which provides a a plenty full of options to influence the typesetting. You can enter such listingsoptions on the "Advanced" page of the "Listing Settings" dialog. For instance, entering

keywordstyle={\color{blue}}

there would typeset all keywords in blue color. For a quick start take a look at other questions with the listings tag – or consult the (excellent!) listings documentation

The reason you do not "see any difference" in your current setup may be a font issue: The culprit is the standard typewriter font in LaTeX, which does not have a boldface version; however, the default of listings is keywordstyle=\bfseries, that is, keywords are typeset in boldface. So just try another typewriter font in "Document -> Settings -> Fonts" and see if this makes a difference.

(BeraMono is a good font for typesetting listings.)

[Tex/LaTex] Biblatex and listings incompatibility…

This minimal example, following your description, shows that it can be compiled without that error message complaining about \citet being undefined:

\documentclass{article}
\usepackage[natbib=true,style=alphabetic-verb,sorting=nty,hyperref,backend=bibtex8]{biblatex}
\begin{document}
al trabajo de \citet{Fernandez2007}.
\end{document}

However, I can confirm, that the error

! Undefined control sequence.
l.4 al trabajo de \citet
                        {Fernandez2007}.

would occur if no options to biblatex are used, i.e. if I just write \usepackage{biblatex}. This doesn't depend on the listings package.

[Tex/LaTex] Fortran syntax highlighting in listings

You have to set the language and the kind of highlighting, e.g.

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{xcolor}
\usepackage{lmodern}
\usepackage{listings}
\lstset{language=[90]Fortran,
  basicstyle=\ttfamily,
  keywordstyle=\color{red},
  commentstyle=\color{green},
  morecomment=[l]{!\ }% Comment only with space after !
}
\begin{document}

\begin{lstlisting}
! Der folgende Fortran-Code ist bei Wikipedia geklaut.
SUBROUTINE test( Argument1, Argument2, Argument3 )
   REAL,              INTENT(IN) :: Argument1
   CHARACTER(LEN= *), INTENT(IN) :: Argument2
   INTEGER,           INTENT(IN), OPTIONAL :: Argument3
   ! This makes sense
END SUBROUTINE
\end{lstlisting}
\end{document}

For more information about the used settings with \lstset see the manual of listings package.

BTW: There are several alternative packages for syntax highlighting. With fortran there seems to be even a package to print Fortran programs. But I've never used this, it cannot be used for syntax highlighting and was made to be used with plainTeX. So maybe if you want to try an alternative, e.g., highlight would be ab better suggestion.
