listings
Consider the following minimal example:
\documentclass{standalone}
\usepackage{listings}
\begin{document}
\begin{lstlisting}[keywordstyle = \textbf, language = SQL, deletekeywords = {time}]
create table Event (id integer primary key, time date);
\end{lstlisting}
\end{document}
This prints ‘time’ in boldface, using the listings package revision 15878 (1.4), TeX Live 2012. How can I make Listings ignore the ‘time’ keyword?
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:
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
classoffsetand 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}
The morekeyword=as option works if you declare it after telling listings that the language to be used is Python:
\documentclass{article}
\usepackage{listings}
\begin{document}
\begin{lstlisting}[language=Python,morekeywords=as]
#!/usr/bin/env python
"""
An animated image
"""
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
\end{lstlisting}
\end{document}
It's perhaps better to define an own environment for Python:
\lstnewenvironment{Python}[1][]
{\lstset{language=Python,
morekeywords=as,
#1}%
}
{}
so that it will be possible to write
\begin{Python}
<Python code>
\end{Python}
possibly giving other local options, say
\begin{Python}[basicfamily=\ttfamily]
<Python code>
\end{Python}

it is defined as an end keyword and can be deleted only with the (deprecated)
deletendkeywords. Looks like a bug to me. However, you have to use the uppercase version of the keyword as it is defined in the language file.:
