# 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.

- 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}}`
