Scheme syntax highlighting for the LaTeX listings package
LaTeX code:
\documentclass{article}
\usepackage{listings}
\usepackage{color}
\usepackage{textcomp}
\lstset{
language=Scheme
}
\begin{document}
\title{A Scheme Listing in \LaTeX}
\date{}
\maketitle
\begin{lstlisting}
;; The Y combinator
(define Y
(lambda (f)
((lambda (x) (f (lambda arg (apply (x x) arg))))
(lambda (x) (f (lambda arg (apply (x x) arg)))))))
;; Factorial function using the Y combinator
(define fact
(Y (lambda (f)
(lambda (n)
(if (<= n 0)
1
(* n (f (- n 1))))))))
\end{lstlisting}
\end{document}
As an alternative to lstlisting, Scheme code can also be included from an external file:
\lstinputlisting{ycombinator.ss}
Rendered:
The scheme-listings directory must be on your TeX search path.
To use LaTeX from the Bash shell, add this to your shell config file (e.g. .bashrc):
export TEXINPUTS=/path/to/scheme-listings/:$TEXINPUTS
For Emacs, use:
(setenv "TEXINPUTS" (concat "/path/to/scheme-listings/:" (getenv "TEXINPUTS")))
