Code snippets

The well-known LATEX command   \verb   typesets code snippets verbatim. The new command\lstinline pretty-prints the code, for example.

var i : integer ;   \lstinline!var i:integer;!

Display code

The  lstlisting  environment typesets the enclosed source code.

f o r i := ma xi nt t o 0 dob e g i n

{do n o t h in g}end ;

W ri te ( C a s e i n s e n s i t i v e ) ;WritE ( P a s c a l k ey wo rd s . ) ;

The environment provides an optional argument. It tells the package to peform special tasks,for example, to print only the lines 2-5:

b e g i n{do n o t h in g}

end ;

Stand alone files

Finally we come to  \lstinputlisting  the command used to pretty-print stand alone files. I hasone optional and one file name argument.

\lstinputlisting[lastline=4]{listings}
