swig: Generate a binding between C and Ruby and prefix the Ruby module with {{foo::bar::}}.

swig

$ swig -ruby -prefix "${foo::bar::}" ${path-to-swig_file-i}

try on your machine

The command you provided is using SWIG (Simplified Wrapper and Interface Generator) to generate Ruby language bindings for a C/C++ library.

Here's a breakdown of the command:

swig: This is the command to execute the SWIG tool.
-ruby: Specifies that Ruby language bindings should be generated.
-prefix "${foo::bar::}": Sets a prefix for the generated code. In this case, the prefix is "${foo::bar::}", which is likely a placeholder for a specific application-specific namespace or module name.
${path-to-swig_file-i}: The path to the SWIG interface file (usually with the .i extension) that describes the wrapping interface.

The command runs the SWIG tool with the given options and tells it to generate Ruby language bindings using the provided SWIG interface file. The -prefix option allows you to specify a custom module or namespace name to be included in the generated code.
