If you're decent with javascript it should not be too much of a big deal to
fix. I can not think of the filename offhand in which the different library
functions are in. Perhaps Jason K can chime in. But if I think is going on
is true, it'll be in a callback looking something like:
exports.export_name = function(param, callback){
var params = param;
var some_function = node_function( params, (error, param2, param3) => {
*if(error){throw error;}*
callback(param3);
});
};
I know . . . thats rather generic. But last I looked at bonescript it was
rather complex and very involved. In some cases, I think it even includes
the kitchen sink ;)
