listings is a LaTeX package for
including source code listings into your LaTeX document.
The Emerald language definition is given in a single .tex file:
listings-emerald.tex.
In general, the file has the following structure:
\lstdefinelanguage{emerald}
{
...
}
Hence, you should use it, roughly, as follows:
\usepackage{listings}
\input{listings-emerald} % An Emerald language definition
If most of your code will be Emerald code, you might as well also do this:
\lstset{language=emerald} % Set Emerald as the default language
If you do the above, then you can ignore all the occurrences of
[language=emerald] below.
To include a code block, use:
\begin{lstlisting}[language=emerald]
...
\end{lstlisting}
To include some code inline (e.g., when discussing an Emerald keyword), use:
\lstinline[language=emerald]^...^
Note, we use ^ around the Emerald code since ^ is not an element
of Emerald syntax. It may however be an element of your Emerald
strings, or characters. In that case, you should pick a different
delimiter. \lstinline accepts any character as the delimiter: it
looks for the first subsequent occurrence of the first character (in
this case, ^).
To include code from a file (probably the best option), use:
\lstinputlisting[language=emerald]{filepath.m}
To include only lines 2-4, use:
\lstinputlisting[language=emerald, linerange=2-4]{filepath.m}
For more about the listings package, see the package documentation
on CTAN.
