description CableSwig creates interfaces to interpreted languages such as Tcl and Python.  

long_description    \
CableSwig is used to create interfaces (i.e. wrappers) to interpreted languages such as Tcl and Python. It was created to produce wrappers for ITK because the toolkit uses C++ structures that SWIG cannot parse (deeply nested template instantiations). CableSwig is a combination tool that uses  GCC_XML as the c++ parser. The input files are  Cable style input files.  The XML produced from the Cable/GCC_XML input files are then parsed and feed into a modified version of SWIG. SWIG is a software development tool that connects programs written in C and C++ with a variety of high-level programming languages. It is used to generate the language bindings to the target language.  Currently, Tcl and Python are supported.  CableSwig consists of four executables: 1) cswig - the main cable swig executable, that takes an xml file from gccxml as input. The xml file should be created from a cable config input file. This program is a modified version of the standard SWIG main. It uses CABLE libraries to parse the input XML from gccxml to create SWIG data structures describing the C++ code to be wrapped.  2) cableidx - a program to generate index files from gccxml xml files. The index files tell cswig what classes are wrapped in which libraries.  This is important because swig needs to know if a class is not wrapped or wrapped in another module, and if it is wrapped which module it is wrapped in.  3) gccxml_cc1plus - A patched version of gcc that has the -fxml option to convert c++ into xml.  4) gccxml - ( www.gccxml.org) the front end program to gccxml_cc1plus.  CableSwig was developed to support ITK, and has not been widely used elsewhere. Not all features of SWIG are currently accessible through CableSwig. Features known to be missing are: * Wrapping of public data members in structs and classes, no accessor routines are created, the original source must provide access methods.
