listingspythonsyntax
I am using package listings to import my Python source code into my LaTeX document. I use the command \lstinputlistings. I have a Python source like
class MyClass(Yourclass):
def __init__(self, my, yours):
bla bla bla...
What should I write in my \lstset command in order to highlight words MyClass, __init__ etc.?
I wouldn't want to write any word I want to be highlighted. I tried using moredelims=[s][\color{teal}]{class}{(} inside lstset but it doesn't work.
It is always good to post a minimal and compilable example, not just code snippets. This way, the answerers do not have to guess what's happening with your problem.
I guess that you are looking for something like this.
\documentclass{article}
\usepackage{listings}
\usepackage{xcolor}
\lstset{language=Python,
morekeywords={as,__init__,MyClass},
keywordstyle=\color{teal}\bfseries,
}
\begin{document}
\lstinputlisting{guess.py}
\end{document}
where guess.py is your sample code snippet. I just added as on the last line to show that morekeywords works.
class MyClass(Yourclass):
def __init__(self, myvar, yours):
bla bla bla... as
Here is the output.
You can also remove __init__ from morekeywords option and use the answers in How to I emphazise all words beginning with ` in an lstlisting and Listings language definition keyword suffixes. So you may put the following code snippet into your preamble.
\lstset{language=Python,
morekeywords={as,MyClass},
keywordstyle=\color{teal}\bfseries,
keywordsprefix=_,
}
Let me know if this works for you.
First, some thoughts on minted: this great package relies on Pygments and AFAIK most of the available styles does support Java annotations. Sadly, as you pointed out, the bw style doesn't highlight annotations.
One possibility is to create an extended version of this style (in order words, create a new style with bw as base) and then include the instruction that sets the formatting for annotations (I just took a quick look at some styles, but failed to determine which instruction is used by Pygments to refer to an annotation).
If you want to try listings instead, I'd go with Pouya's suggestion on using custom delimiters. The reason is that, in my humble opinion, since annotations are syntactic metadata, they cannot be treated as keywords or comments, hence a different style to represent them would be a wiser choice.
I know you are using a black and white theme, but I decided to create a colored output just for us to see which style is being applied to each identifier. The concept would be the same, just replace color occurrences by the font series you want.
In my code, I'd create two delimiters:
moredelim=[il][\textcolor{pgrey}]{$$},
moredelim=[is][\textcolor{pgrey}]{\%\%}{\%\%}
The first, $$, is applied to the whole line and it can be used for annotations that are in lines of their own (think of a single line comment here). The second one, %% ... %%, behaves like a multiline comment, which encloses everything that is inside these delimiters, and it's useful for annotations that are applied inline to methods or fields.
A sample code is as follows (the Java example here is a courtesy of Project Lombok):
\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{inconsolata}
\usepackage{color}
\definecolor{pblue}{rgb}{0.13,0.13,1}
\definecolor{pgreen}{rgb}{0,0.5,0}
\definecolor{pred}{rgb}{0.9,0,0}
\definecolor{pgrey}{rgb}{0.46,0.45,0.48}
\usepackage{listings}
\lstset{language=Java,
showspaces=false,
showtabs=false,
breaklines=true,
showstringspaces=false,
breakatwhitespace=true,
commentstyle=\color{pgreen},
keywordstyle=\color{pblue},
stringstyle=\color{pred},
basicstyle=\ttfamily,
moredelim=[il][\textcolor{pgrey}]{$$},
moredelim=[is][\textcolor{pgrey}]{\%\%}{\%\%}
}
\begin{document}
\begin{lstlisting}
/**
* This is a doc comment.
*/
package com.ociweb.jnb.lombok;
import java.util.Date;
import lombok.Data;
import lombok.EqualsAndHashCode;
import lombok.NonNull;
$$@Data
$$@EqualsAndHashCode(exclude={"address","city","state","zip"})
public class Person {
enum Gender { Male, Female }
// another comment
%%@NonNull%% private String firstName;
%%@NonNull%% private String lastName;
%%@NonNull%% private final Gender gender;
%%@NonNull%% private final Date dateOfBirth;
private String ssn;
private String address;
private String city;
private String state;
private String zip;
}
\end{lstlisting}
\end{document}
The output:
Hope it helps. :)

I'd consider running your code through pygments to generate the latex, probably using the minted package. You can get some details here https://stackoverflow.com/questions/1966425/source-code-highlighting-in-latex#1985330 .
