Our compiler provides two different user interfaces: one is a command line interface fully written in C++, using the “Task” system, and the other is a binding of the primary functions into the Python script language (see Python. This binding is automatically extracted from our modules using SWIG.
The SWIG home page reads:
SWIG is a software development tool that connects programs written in C and C++ with a variety of high-level programming languages. SWIG is primarily used with common scripting languages such as Perl, Python, Tcl/Tk, and Ruby, however the list of supported languages also includes non-scripting languages such as Java, OCAML and C#. Also several interpreted and compiled Scheme implementations (Guile, MzScheme, Chicken) are supported. SWIG is most commonly used to create high-level interpreted or compiled programming environments, user interfaces, and as a tool for testing and prototyping C/C++ software. SWIG can also export its parse tree in the form of XML and Lisp s-expressions. SWIG may be freely used, distributed, and modified for commercial and non-commercial use.
