Description

The Koala-compiler package forms an Open Source implementation of the Koala compiler as developed by Philips Research. The package provides an open compiler implementation that can be used for research and for education purposes.

Koala is a component definition language used by Philips consumer electroniccs to model components (as C modules), composition (as C compilation and linking), and variability (as CPP macros and partial evaluation).

The Koala component model consists of a component language, which supports definition of:

• diversity (by means of a diversity interfaces)
• component compositions

Component compositions consist of collections of components and wires that connect provides and requires interfaces (see picture below).
