Obtain all functions in a file in Node.js

I have some functions inside a file. I'm trying to obtain all functions in that file, from within that file. Normally, all functions are in the window object, but I'm using Node.js, which does not seem to have a window object.

Say I have something along the lines of the following in a file:

fun开发者_开发技巧ction foo() {}
function bar() {}

then:

1. Are the functions saved in some global object?
2. If not, how can I access these functions without knowing their names? Can I iterate through all existing functions and obtain them in such a way?

The following is a common pattern

var foo = exports.foo = function() {
    // ...
}

This way its written to exports and you can access it locally as foo

You want to get access to the current scope object but it's impossible in JavaScript.

Your functions are wrapped in a closure. Remember, node wraps file modules within something like this

var module = { exports: {}};
(function(module, exports){
    // your file module content
})(module, module.exports);

They are locals. Assign functions to an object, exports or global to enumerate them.
