\maketitle

\section{Introduction}
some basic examples:
\begin{lstlisting}[language=Macaulay2]
R=QQ[x,y]; factor(x^3-y^3)
res coker vars R
OO_(Proj(R/(x^3-y^3)))^{1,2}
matrix {{1,2},{3,4}}
\end{lstlisting}

The code can also be inline: \lstinline[language=Macaulay2]!gcd(1300,75)!.
More:
\begin{lstlisting}[language=Macaulay2]
318/46
exp 3.73767
\end{lstlisting}
strings and nets:
\begin{lstlisting}[language=Macaulay2]
"hehe"
( "haha123456789"
||"hoho!@#$%^&*(")
{oo,ooo}
\end{lstlisting}
printing:
\begin{lstlisting}[language=Macaulay2]
for i from 1 to 8 do print((i+ii)^2)
\end{lstlisting}

\section{Reusing output}
The output {\tt o5} is \macoutput{5}.
The nonexistent output {\tt o11} is \macoutput{11}.

\section{Inputting from external file}
Some more code:
\lstinputlisting[language=Macaulay2]{ex.m2}

\section{Packages}
packages that have a {\tt tex} output will work:
\begin{lstlisting}[language=Macaulay2]
needsPackage "Posets";
booleanLattice 3
needsPackage "VectorGraphics";
Circle{"fill"=>"red"}
\end{lstlisting}

\section{Changing key/values}
\begin{lstlisting}[showstringspaces=true,language=Macaulay2,basewidth={1.5ex}]
"some weird spacing  and string style"
\end{lstlisting}

\section{Help}
\begin{lstlisting}[language=Macaulay2]
help cohomology
\end{lstlisting}

\section{Tricky examples}
\dots for testing purposes only
\begin{lstlisting}[language=Macaulay2]
-- some tricky examples
\end{lstlisting}
A bunch of complicated cases: a multi-line example
\begin{lstlisting}[language=Macaulay2]
f = i -> (
-- that's dumb
i+1
)
\end{lstlisting}
and another weirder one:
\begin{lstlisting}[language=Macaulay2]
I=ideal 0; f = i -> (
i+1)
\end{lstlisting}
finally:
\begin{lstlisting}[language=Macaulay2]
a=1;b=2;
c=3;
\end{lstlisting}
That last one has no output.
