This repository contains a simple program that wraps the DukTape embedded JavaScript interpreter and implements the required platform-specific functionality for module loading. It also includes a program that generates C code for FFI.

Given a C file, the ffigen program writes (to standard output) a C file that can be compiled into a library and will

To compile the example test, run these commands:

$ make
$ cd examples
$ ../ffigen test.c > generated.c 
$ indent generated.c
$ clang -g wrapper.c -fPIC -shared -o test.so

You can then run the tst.js example with jsrun and it will load the shared library and be able to find the relevant functions.
