Oz (programming language)

Oz is a special kind of programming language. It helps people learn about programming in many ways. It was created at the Université catholique de Louvain by Gert Smolka and his students in 1991. After that, more people and groups around the world helped develop it.

In 1996, researchers at the Swedish Institute of Computer Science began working on Oz. Since 1999, an international team called the Mozart Consortium has been in charge of developing Oz. This group includes Saarland University, the Swedish Institute of Computer Science, and the Université catholique de Louvain.

Today, the main way people use Oz is through the Mozart Programming System. This system works on many types of computers, including Unix, FreeBSD, Linux, Windows, and macOS. It is shared with an open source license, so anyone can use, change, and share it freely. The book Concepts, Techniques, and Models of Computer Programming is the main guide for learning about Oz.

Language features

Oz is a special kind of programming language. It uses ideas from many different ways of writing computer code. It supports logic, functional, imperative, object-oriented, constraint, distributed, and concurrent programming. This means it can handle many different tasks.

Oz is good for solving problems with limits and working across networks. It makes it simple to create programs that can keep running even if parts of the system fail. Oz also uses a special way to show things on the screen, called QTk.

Language overview

Oz is a programming language with a few basic data types that can be used in many ways.

Basic data structures include numbers, records for grouping data, tuples, and lists. Variables in Oz start with an uppercase letter, and functions can be used in flexible ways. Oz also supports concurrent programming, where parts of a program can run at the same time. This makes it easy to handle many tasks together without changing the final result.

The language includes features for creating objects and managing state, allowing it to support object-oriented programming with simple rules.

Execution speed

Programs written in the Oz programming language using the Mozart compiler (version 1.4.0) run slowly. In tests from 2012, they were about 50 times slower compared to programs written in the C language using the GNU Compiler Collection.
