[Tex/LaTex] Highlight and Textcolor

colorhighlighting

I was following this question to highlight and color the text. It worked fine except for a few exceptions.

First, I checked SDrolet's suggestion in which the \color option didn't work for me. It colors the text until the end of the document instead of just coloring the words inside the enclosing braces. Then, I tried user11232's suggestion too. In this case, I am able to color the words inside the braces, but couldn't change the color of the text-box while using \hl.

Am I missing some packages or any options in packages?

Here is an example code using "xcolor" package

\documentclass{article}
\usepackage{hyperref}
\usepackage{xcolor}
%\usepackage{color,soul}
\begin{document}
\section{Random Text}
\begin{enumerate}
  \item Integer nibh magna, scelerisque sit amet gravida non. Suspendisse quis felis sed augue laoreet ultricies. \color{green}{Aliquam erat volutpat}. Aliquam a orci sit amet mauris rutrum volutpat id et turpis. Fusce tellus risus, sodales vitae augue sed, ullamcorper elementum nibh. Suspendisse sit amet ultricies leo. 
\end{enumerate}
\section{Random Text - 2}
\end{document}

and it's output.

Thank you in advance. Any help is much appreciated. 🙂

Best Answer

Making a parallel with, for example, how \bfseries and \textbf{} work, you should use

{\color{green} text to be colored, works until the group ends}. This 
is not colored anymore

or

text text \textcolor{green}{green text} default color text.

The first form will allow the color to extend between paragraphs, while the second one will throw an error.

[Tex/LaTex] How to highlight operators and brackets in a C listing

Here is a workaround that doesn't break one-line comments and only applies the desired style to operators outside comments and strings.

Caveats:

I've had to define all digits as "letters" to prevent my operator style from being applied to them; there may be side effects associated with that.
Outside comments and strings, the operator style will be applied to all characters that listings classifies as "other".

enter image description here

\documentclass{article}

\usepackage{xcolor}
\usepackage{listings}

\newcommand\opstyle{\color{red}} % <--- customise operator style here

\makeatletter

\lstset
{%
  language=C++,
  alsoletter=0123456789,% to prevent \opstyle from being applied to digits
}

% Hook into listings
\lst@AddToHook{OutputOther}{\ProcessOther@silmeth}

% helper macro
\newcommand\ProcessOther@silmeth
{%
  \ifnum\lst@mode=\lst@Pmode%     % If we're in `Processing' mode...
    \def\lst@thestyle{\opstyle}%  % ... redefine the style locally
  \fi%
}

\makeatother

\begin{document}
\begin{lstlisting}[]
int i = 0;
if(i > 1) && (1/2 < 2) {

    // one-line comment ()={}><;&

    printf("string: ()={}><;&");

    /*
      block comment ()={}><&;
    */
}
\end{lstlisting}
\end{document}

[Tex/LaTex] the difference between \textcolor and \color

Despite the name \textcolor also works in math mode. The main difference is just one of syntax, \textcolor takes text as an argument (like \textrm) \color affects all text to the end of the group (like \rmfamily). However \textcolor also executes \leavevmode which makes the color special occur in a much less destructive place as part of the paragraph rather than on a vertical list. So \textcolor is usually a better choice unless you are setting a colour for a large amount of text, such as the whole document.
