Well, from the very beginning of my course I have to be able to write documents in
So, I found listings, great output! And even better, I could make my own style to one language. After reading the manual I did it for Haskell. I love the output.
You can see an example of that here(.pdf).
A simple definition of some colors to highlight our code:
\definecolor{gray_ulisses}{gray}{0.55}
\definecolor{castanho_ulisses}{rgb}{0.71,0.33,0.14}
\definecolor{preto_ulisses}{rgb}{0.41,0.20,0.04}
\definecolor{green_ulises}{rgb}{0.2,0.75,0}
And here it is, the thing that do things 🙂

And now, to use it, we define a new environment:
\lstnewenvironment{code}
{\textbf{Haskell Code} \hspace{1cm} \hrulefill \lstset{language=HaskellUlisses}}
{\hrulesmallskip}
Now to write Haskell code in our
\begin{code}
module Main(main) where
main :: IO()
main = putStrLn $ "LaTeX listings is cool!"
\end{code}
Because I’m not so good at web design I use this blog layout (that I like), but some of the code may not be seen, if you want to see an example of a
