Hi guys. I know that: a) for papers we usually write code in black and white and b) even when we may want colors like books or thesis, we still may not want to add colors. Anyway, for my thesis, I do want to make the code a little bit nicer and so I did some Smalltalk syntax highlighting with listings package. Not sure if this would be helpful for someone else, but just in case, I paste at the end the code. Basically, I can detect (and therefore, choose a color/style): globals/classes (start with uppercase), keywords, comments, strings, symbols and numbers. I also attach an screenshot. Cheers btw, thanks to Lukas and Luc for their help. % Source Code \usepackage{color} \usepackage{textcomp} \usepackage{listings} % \usepackage{needspace} % \usepackage{ulem} \definecolor{source}{gray}{0.95} % my comment style \newcommand{\myCommentStyle}[1]{{\footnotesize\ttfamily\itshape\color{gray!100!white} #1}} % my string style \newcommand{\myStringStyle}[1]{{\footnotesize\ttfamily\color{violet!100!black} #1}} % my symbol style \newcommand{\mySymbolStyle}[1]{{\footnotesize\ttfamily\color{violet!100!black} #1}} % my keyword style \newcommand{\myKeywordStyle}[1]{{\footnotesize\ttfamily\color{green!70!black} #1}} % my global style \newcommand{\myGlobalStyle}[1]{{\footnotesize\ttfamily\color{blue!100!black} #1}} % my number style \newcommand{\myNumberStyle}[1]{{\footnotesize\ttfamily\color{brown!100!black} #1}} \lstset{ language={}, % characters tabsize=3, escapechar={!}, keepspaces=true, breaklines=true, alsoletter={\#}, breakautoindent=true, columns=fullflexible, showstringspaces=false, % background frame=single, aboveskip=1em, % automatic space before framerule=0pt, basicstyle=\footnotesize\ttfamily\color{black}, keywordstyle=\myKeywordStyle,% keyword style commentstyle=\myCommentStyle,% comment style frame=single,% backgroundcolor=\color{source}, % numbering numbersep=5pt, numberstyle=\myNumberStyle, numberfirstline=true, % caption captionpos=b, % formatting (html) moredelim=[is][\textbf]{<b>}{</b>}, moredelim=[is][\textit]{<i>}{</i>}, moredelim=[is][\uline]{<u>}{</u>}, moredelim=[is][\color{red}\uwave]{<wave>}{</wave>}, moredelim=[is][\color{red}\sout]{<del>}{</del>}, moredelim=[is][\color{blue}\uline]{<ins>}{</ins>}, % smalltalk stuff morecomment=[s][\myCommentStyle]{"}{"}, % morecomment=[s][\myvs]{|}{|}, morestring=[b][\myStringStyle]', moredelim=[is][]{<sel>}{</sel>}, moredelim=[is][]{<rcv>}{</rcv>}, moredelim=[is][\itshape]{<symb>}{</symb>}, moredelim=[is][\scshape]{<class>}{</class>}, morekeywords={true,false,nil,self,super,thisContext}, identifierstyle=\idstyle, } \makeatletter \newcommand*\idstyle[1]{% \expandafter\id@style\the\lst@token{#1}\relax% } \def\id@style#1#2\relax{% \ifnum\pdfstrcmp{#1}{\#}=0% % this is a symbol \mySymbolStyle{\the\lst@token}% \else% \edef\tempa{\uccode`#1}% \edef\tempb{`#1}% \ifnum\tempa=\tempb% % this is a global \myGlobalStyle{\the\lst@token}% \else% \the\lst@token% \fi% \fi% } \makeatother \lstset{literate=% *{0}{{{\myNumberStyle{0}}}}1 {1}{{{\myNumberStyle{1}}}}1 {2}{{{\myNumberStyle{2}}}}1 {3}{{{\myNumberStyle{3}}}}1 {4}{{{\myNumberStyle{4}}}}1 {5}{{{\myNumberStyle{5}}}}1 {6}{{{\myNumberStyle{6}}}}1 {7}{{{\myNumberStyle{7}}}}1 {8}{{{\myNumberStyle{8}}}}1 {9}{{{\myNumberStyle{9}}}}1 } %\newcommand{\ct}{\lstinline[backgroundcolor=\color{white}]} \newcommand{\needlines}[1]{\Needspace{#1\baselineskip}} \newcommand{\lct}{\texttt} \lstnewenvironment{code}{% \lstset{% % frame=lines, frame=single, framerule=0pt, mathescape=false } }{} \newenvironment{codeNonSmalltalk} {\begin{alltt}\sffamily} {\end{alltt}\normalsize} -- Mariano http://marianopeck.wordpress.com
