[Tex/LaTex] Define listings language with multiple keyword groups

keywordslistings

I wanted to used syntax highlighting for a language unsupported by the listings package. Right now I have it almost working, but not completely. This is the MWE:

\documentclass{article}
\usepackage{listings,color}

% Define colors
\definecolor{codeBlue}{RGB}{0,0,255}
\definecolor{codeGreen}{RGB}{0,128,0}
\definecolor{codePurple}{RGB}{128,0,255}
\definecolor{codeOrange}{RGB}{255,128,128}
\definecolor{codePink}{RGB}{255,0,255}
\definecolor{codeGray}{rgb}{0.5,0.5,0.5}

% Define language style
\lstdefinestyle{apdl-modified}
    {       
        extendedchars=true,
        alsoletter={*},
        alsoletter={'},
        keywordstyle=\color{codeOrange},
        keywordstyle=[2]\color{codePurple},
        keywordstyle=[3]\color{codeBlue},
        keywordstyle=[4]\color{codePink},
        otherkeywords={
            /solve,
            /angle
        },
        keywords=[2]{
            *abbr,
            *dim
        },
        keywords=[3]{
            m,
            d
        },
        keywords=[4]{
            ',
            -,
            ",
            \%,
            (,
            ),
            ,,
            .,
            :,
            ;,
            ?,
            ^,
            ~,
            +,
            <,
            =,
            >
        },
        sensitive=false, % keywords are not case-sensitive
        morecomment=[l]{!}, % l is for line comment
        commentstyle=\color{codeGreen}, % style of comments
        numberstyle=\tiny\color{codeGray}
    }

% Define Language with previously defined style
\lstdefinelanguage{APDL}{style=apdl-modified}

\begin{document}
\begin{lstlisting}[language=APDL]
*dim,m,table,2,1, ,time
m(1,0,1) = 0.0001
m(1,1,1) = 0
m(2,0,1) = time
m(2,1,1) = time*speed

d,p51x, , %m% , , , ,ux,, , , ,

/solve
\end{lstlisting}
\end{document}

Which gives me:

The second and the fourth keywordstyle are not working, and I do not understand why. Anyone an idea?

Best Answer

alsoletter={*} and alsoletter={'} must be in a single definition: alsoletter={*,'}

[Tex/LaTex] Listings language definition keyword suffixes

You can use the keywordsprefix=<prefix> to specify that anything beginning with the <prefix> is considered a a keyword. The MWE below highlights any word beginning with B in blue, but leaves other text alone:

enter image description here

However you should note the following limitations form the listings documentation:

The prefix is always case sensitive.

Only one prefix can be defined at a time.

If used standalone outside a language definition, the key might work only after selecting a nonempty language (and switching back to the empty language if necessary).

The key does not respect the value of classoffset and has no optional class argument.

\documentclass{article}
\usepackage{listings}%
\usepackage{xcolor}

\lstset{%
    backgroundcolor=\color{yellow!20},%
    basicstyle=\small\ttfamily,%
    numbers=left, numberstyle=\tiny, stepnumber=2, numbersep=5pt,%
    keywordstyle=\color{blue}\bfseries,
    language=Java,
    keywordsprefix=B,
    }%

\begin{document}
\begin{lstlisting}
    ABC BGT DEF
    BLE XYZ MWS
    BNE DNW QES
    ABN BEQ MWE
\end{lstlisting}
\end{document}

[Tex/LaTex] listings: General settings for a language seem to be overwritten/not respected

You seem to think that \lstset sets parameters for one specified language, i.e., the language given within \lstset. That is not how it works. Your code first sets the default language for all listings of your document to TeX, then it sets it to R, and so on. Similarly, it sets three default keywords for all listings of your document (if, else, function), but when you typeset your R listing, the keyword list that belongs to R overwrites the default keyword list.

What you actually want is probably best achived with styles, or you define a new language based on R, or a new dialect of R. Let's try with styles:

\documentclass{scrartcl}

\usepackage[T1]{fontenc}
\usepackage[american]{babel}
\usepackage{xcolor}
\usepackage{fancyvrb}
\usepackage{listings}

% this style should be active for all lstlistings environments
\lstdefinestyle{all}{
  basicstyle=\ttfamily\small,
  frame=lrtb, framerule=1pt, framexleftmargin=1pt,
  showstringspaces=false
}

% this style should be active (additionally to "all") for "input" lstlistings environments
\lstdefinestyle{input}{
  commentstyle=\itshape\color{red},
  keywordstyle=\color{blue}
}

\lstdefinestyle{newLaTeXsettings}{
  style=all,
  keywords={},
  otherkeywords={}
}


% listings settings for R (should hold for all R listings in general)
\lstdefinestyle{newRsettings}{
  style=all,
  literate={<-}{{$\leftarrow$}}2,% this is respected
  keywords={if, else, function},% this is not respected
  otherkeywords={}
}

\begin{document}

\begin{lstlisting}[language={[LaTeX]TeX}, style=input, style=newLaTeXsettings]
\begin{enumerate}
\item foo % bar
\end{enumerate}
\end{lstlisting}

\begin{lstlisting}[language=R, style=input, style=newRsettings]
x <- 4
s <- lapply(1:10, function(z) z+x)
k <- sapply(1:10, function(z) z+2*x) # other case
\end{lstlisting}

\end{document}
