I'd like to make all space characters in the code gray. Is there an easy way to do this?
Is there something like spacestyle
(I've commented it)?
\documentclass[a4paper, 10pt]{book}
\usepackage[UTF8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[T2A]{fontenc}
\usepackage[russian, ukrainian]{babel}
\usepackage{amsmath}
\usepackage{listings}
\usepackage[usenames, dvipsnames]{color}
\lstset{%
language = [77]Fortran,
basicstyle = \ttfamily,
keywordstyle = \color{black},
stringstyle = \color{Gray},
showspaces = true,
% spacestyle = \color{Gray}
numbers = left,
numberstyle = \ttfamily \color{black}
}
\begin{document}
\begin{lstlisting}
PROGRAM HELLO
WRITE(*, *) "Hello, World!"
END PROGRAM
\end{lstlisting}
\end{document}
Also I want to change all spaces to gray bullets. Is it possible?
Best Answer
The
listings
package uses\lst@visiblespace
for these spaces so you just need to define it:Here's the latex code. I removed your font encoding as I didn't want to generate all of the required fonts.
