[Programming] Writing Wrapper for Native Code ~What is SWIG?~

I cannot believe this...
I spend so much time just writing all kinds of wrappers for stupid native codes...
Well,... SWGI can do it for you...

Following is the copied description on SWIG from their website... 

What is SWIG?

SWIG is a software development tool that simplifies the task of interfacing different languages to C and C++ programs. In a nutshell, SWIG is a compiler that takes C/C++ declarations and creates the wrappers needed to access those declarations from other languages including including Perl, Python, Tcl, Ruby, Guile, and Java. SWIG normally requires no modifications to existing code and can often be used to build a usable interface in only a few minutes. Possible applications of SWIG include:

• Building interpreted interfaces to existing C programs.
• Rapid prototyping and application development.
• Interactive debugging.
• Reengineering or refactoring of legacy software into a scripting language components.
• Making a graphical user interface (using Tk for example).
• Testing of C libraries and programs (using scripts).
• Building high performance C modules for scripting languages.
• Making C programming more enjoyable (or tolerable depending on your point of view).
• Impressing your friends.
• Obtaining vast sums of research funding (although obviously not applicable to the author).

SWIG was originally designed to make it extremely easy for scientists and engineers to build extensible scientific software without having to get a degree in software engineering. Because of this, the use of SWIG tends to be somewhat informal and ad-hoc (e.g., SWIG does not require users to provide formal interface specifications as you would find in a dedicated IDL compiler). Although this style of development isn't appropriate for every project, it is particularly well suited to software development in the small; especially the research and development work that is commonly found in scientific and engineering projects. However, nowadays SWIG is known to be used in many large open source and commercial projects.
