[Tex/LaTex] Writing HTML code directly from LaTeX

tex4ht

At exporting a LaTeX file to HTML via tex4ht I have to write some HTML comments to the HTML source. So I would like to write the HTML code in the LaTeX file and let tex4ht export it directly. How can I achieve this? Are there some special LaTeX commands to do this?

Best Answer

\def\HCode#1{}
...
\begin{document}
...
\HCode{<!--comment-->}

It works. tex4ht writes the comment and pdflatex ignores the tag. Fine.

[Tex/LaTex] LaTeX to HTML preserving code coloring from listings

It is perhaps possible to hook somewhere in the listings commands so that they write sensible class instructions. But on the other side listings is very complicated and this could easily break. Imho a more simple approach is with fonts: if every style is connected to a different font then tex4ht surrounds the chars with classes which you can set throught css. Here an example (it runs only with htlatex, if you want to use pdflatex you will have to move the \Css to a configuration file:

\documentclass{article}
\usepackage{color}
\usepackage{listings}
\usepackage[T1]{fontenc}

\lstset{
    basicstyle=\ttfamily,
    language=[Sharp]C,
    keywordstyle=\rmfamily\bfseries,
    commentstyle=\sffamily,
}
\def\mystyle{}


\begin{document}

\Css{div.lstlisting .ectt-1000 {font-family: monospace;color:blue}}
\Css{div.lstlisting .ecss-1000 {font-family: monospace;color:green}} 
\Css{div.lstlisting .ecbx-1000 {font-family: monospace;color:red}} 


\section{Test!}

{\ttfamily hello}, {\sffamily Hello} {\bfseries Hello}


\begin{lstlisting}
int x = 10;

// This is a comment
string str = "hello";
\end{lstlisting}
\end{document}

LaTeX Document – Correct Way to Check for LaTeX, PDFLaTeX, and HTML

As you want to test for tex4ht using \@ifpackagesloaded, you do not want to load tex4ht in every job! This will interfere with the standard pdfLaTeX settings and make PDF creation more difficult. Instead, leave the package loading out (but include the test) and htlatex will make the necessary arrangements to load tex4ht when you are creating HTML files.
