Introduction

Many software professionals recognize the value of hybrid compiled/interpreted software environments. Compiled languages such as C and C++ provide efficiency, speed, and flexible data structure representation. Interpreted languages such as Tcl or Python remove the compile/link cycle from the development process, are indispensable for prototyping, and provide a multitude of packages for creating GUI's, numerics, and web access.

The creation of such hybrid environments is difficult. Typically C/C++ developers will manually add the interpreted language binding, or use semi-automatic tools such as SWIG. In some cases, custom wrapper generators have been created that are specialized to a particular system, such as the Visualization Toolkit (VTK). However, no fully automatic, general wrapping system has been available. As a result, mixed language systems are less common than might be expected, requiring excessive resources to develop.

Kitware, Inc. has developed an open-source wrapping package called CABLE (CABLE Automates Bindings for Language Extension). It is a tool designed to automatically generate bindings to C++ classes for use in interpreted languages. This system works in conjunction with GCC-XML, an extension to the GCC compiler. GCC-XML, also developed by Brad King at Kitware, is used to parse arbitrarily complex C++ code and then produce an XML representation. This representation is then processed by CABLE to generate wrappers. See the page on Running CABLE for more details.

CABLE was developed by Brad King at Kitware as part of the NLM Insight Segmentation and Registration Toolkit project.
