This is a minimal example project for calling C++ from Janet.
Usage:
Make sure you have Janet and jpm installed.
Then run jpm build from the root of this directory. It will handle compiling the shared library (rectangle_bindings.cpp and rectangle.h) and then compile the main.janet file into an executable.
If you don't want to use the executable and just run main.janet as a script, still run jpm build to ensure the rectangle library is built and then just call janet main.janet and it should find the library in the build/ directory.
The resulting executables are in build/
