The Pizza Compiler
The Pizza language is an extension to Java with three new features:
The shortest way to write and compile a Pizza program successfully
Install a Java run-time environment
You'll find Java run-time environments (JREs) e.g. on
Sun Microsystem's site. The Pizza
compiler is known to work with the Java 2 Runtime Environment, Standard Edition,
Download and install the JRE.
To verify your installation run java -version. This should say something like
java version "1.3.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-b24)
Java HotSpot(TM) Client VM (build 1.3.1-b24, mixed mode)
Download the latest Pizza release
Pizza distributions are found at
You can simply download the binary release which is called something like pizza-x.x.jar.
Put the jar file where you think is a good place to install programs. On Microsoft Windows you
might want to use C:\Java\Pizza\. For Unix platforms /usr/local/pizza/ might be
the place for it. We'll refer to the place where you installed it as $PIZZA_HOME.
To verify your Pizza installation run java -jar $PIZZA_HOME/pizza-x.x.jar -version. This should say something like
Pizza v1.0g, 1-October-2001, Copyright (c) 1996-98 Martin Odersky.

Whenever you want to run the Pizza compiler, you'll use java -jar $PIZZA_HOME/pizza-x.x.jar
and add any parameters to it.
Writing a Pizza program
From here you might want to go on to the Pizza tutorial which explains how to use
the Pizza specific features in the language.
If it doesn't work out this easily, you can contact of
the Pizza compiler's users' mailing list.
