# swig

> Generate bindings between C/C++ code and various high level languages such as JavaScript, Python, C#, and more.
> It uses special `.i` or `.swg` files to generate the bindings (C/C++ with SWIG directives), then outputs a C/C++ file that contains all the wrapper code needed to build an extension module.
> More information: <https://www.swig.org>.

- Generate a binding between C++ and Python:

`swig -c++ -python -o {{path/to/output_wrapper.cpp}} {{path/to/swig_file.i}}`

- Generate a binding between C++ and Go:

`swig -go -cgo -intgosize 64 -c++ {{path/to/swig_file.i}}`

- Generate a binding between C and Java:

`swig -java {{path/to/swig_file.i}}`

- Generate a binding between C and Ruby and prefix the Ruby module with `foo::bar::`:

`swig -ruby -prefix "{{foo::bar::}}" {{path/to/swig_file.i}}`
