How to install
Just run npm install kissdi
How to use
Also just simple!
// kissdi has a function named 'inject' as library's member.inject = require("node-kissdi").inject/* * To inject a function, we need to create a "target function" * the target function should be an instance of Array that has a function as * a last element. i.e. */var target = [ "foo", "bar", function (foo, bar) { return function () { return [foo, bar]; }; }]; // Then, call inject like thisvar injected_func = inject( target, { "foo": "Hello", "bar": "World" }); // To obtain the return value from the target, call inject_func.invokevar func = inject_func.invoke();// Because the target function is a closure, we need to call it once more.// Therefore, needs to call func if we obtain the result listvar list = func()// expect: ["Hello", "World"] // Calling invoke with an object that has corresponding paramenters as keys,// the corresponding parameters are replaced with the given values.var func = inject_func.invoke({ "foo": "Konichiwa"});// func() returns ["Konichiwa", "World"]var list = func()// expect: ["Konichiwa", "World"]
