swk-linker

Creates a function from a list of functions.

Each function in the list will be provided three arguments
The first argument is the arguments array passed in to the wrapper function
the second argument is the next available function
the last argument is the last available function

calling the next function will (unsurprisingly) call the next function in the list
calling the done function will (also unsurprisingly) call the last function
...unless the function is the last in the list, in which case next and done will both noop

var linker = require("swk-linker")
linked = linker(
    function (args, next, done) {
        // args === ['foo'] - see below
        next();
    },
    function (args, next, done) {
        done();
    },
    function (args, next, done) {
        // doesn't get called
    },
    function (args, next, done) {
        next() // noop
        done() // noop
    });

linked('foo');
