Hi everyone,

Looking through the forums I’m not quite sure if this has been answered or not. I’m looking to call a .ts function from Cpp. I see mention of using shim:: when going the opposite way, but not sure about going from ts to Cpp. Simple example:

foo.ts has function  
`
namespace tsFunction
{
export fooBar(something:number)
{
…
…
}
}`

`
`

fib.cpp has function  
`
namespace cppFunction {`

`
`

`void fib()
{
fooBar(11);
}
}
`  
How can I make this possible? I’ve tried doing something like:  
`
//% shim=tsFunction::fooBar
`

Any help appreciated.

Thanks,  
Josh
