Derivatives

A note on terminology: There are a lot of things with similar meanings/use-cases around: subscriptions, reactions, derived atoms, view models. I'll introduce another to make things even worse: derivative. A derivative implements IWatchable and it's value is the result of applying a function to the value of other things (sources) implementing IWatchable. Whenever any of the sources change the value if the derivative is updated.

Why this library

Let's assume you're hooked about the idea of storing all your application state in a single atom (db). (Why this is a great idea is covered elsewhere.)

Most of your components don't need the entirety of this state and instead receive a small selection of it that is enough to allow the components to do their job. Now that data is not always a subtree (i.e. (get-in db ...)) but might be a combination of various parts of your state. To transform the data in a way that it becomes useful for components you can use a function: `(f @

My Vimium Key Bindings (Emacs-Style)

This is a full set of key bindings (as of Vimium v1.45); covering all Vimium functionality. I have tried to map all Vimium functionality to comparable Emacs functionality (whenever possible). In cases where there is no equivalent, those commands are prefixed by <c-g> (indicating <c-g>oogle Chrome; and because <c-g> does not conflict with other Emacs shortcuts at all).

Commented Shortcuts: There are a few Emacs-style shortcuts that are simply not possible in Vimium. All of my shortcuts (including those which were not possible; i.e. where I used a decent alternative) have been commented below. This should help to clarify my rationale.

_Compatibility: All of these shortcuts were tested on Mac OS X (Mavericks). Please note that all of my shortcuts operate under the assumption that your Emacs Meta key is the ⌥ Alt/Option key. This really was my only choice, because the ⌘ key is already used in Chrome for shortcuts that c
