+# Eve
+
+Tiny event helping JavaScript library.
+
+## eve(name, scope, varargs)
+Fires event with given `name`, given scope and other parameters.
+
+### Parameters
+- _name_ **string**
+ name of the _event_, dot (`.`) or slash (`/`) separated
+- _scope_ **object**
+ context for the event handlers
+- _varargs_ **...**
+ the rest of arguments will be sent to event handlers
+
+**Returns:** **object** array of returned values from the listeners. Array has two methods `.firstDefined()` and `.lastDefined()` to get first or last not `undefined` value.
+
+## eve.listeners(name)
+Internal method which gives you array of all event handlers that will be triggered by the given `name`.
+
+### Parameters
+- _name_ **string**
+ name of the event, dot (`.`) or slash (`/`) separated
+
+**Returns:** **array** array of event handlers
+
+## eve.separator(separator)
+If for some reasons you don’t like default separators (`.` or `/`) you can specify yours
+here. Be aware that if you pass a string longer than one character it will be treated as
+a list of characters.
+
+### Parameters
+- _separator_ **string**
+ new separator. Empty string resets to default: `.` or `/`.
+
+
+## eve.on(name, f, name, f)
+Binds given event handler with a given name. You can use wildcards “`*`” for the names:
+
+```js
+eve.on("*.under.*", f);
+eve("mouse.under.floor"); // triggers f
+```
+Use eve to trigger the listener.
+
+### Parameters
+- _name_ **string**
+ name of the event, dot (`.`) or slash (`/`) separated, with optional wildcards
+- _f_ **function**
+ event handler function
+- _name_ **array**
+ if you don’t want to use separators, you can use array of strings
+- _f_ **function**
+ event handler function
+
+**Returns:** **function** returned function accepts a single numeric parameter that represents z-index of the handler. It is an optional feature and only used when you need to ensure that some subset of handlers will be invoked in a given order, despite of the order of assignment.
+
+### Example:
+```js
+eve.on("mouse", eatIt)(2);
+eve.on("mouse", scream);
+eve.on("mouse", catchIt)(1);
+```
+This will ensure that `catchIt` function will be called before `eatIt`.
+
+If you want to put your handler before non-indexed handlers, specify a negative value.
+Note: I assume most of the time you don’t need to worry about z-index, but it’s nice to have this feature “just in case”.
+
+
+## eve.f(event, varargs)
+Returns function that will fire given event with optional arguments.
+Arguments that will be passed to the result function will be also
+concated to the list of final arguments.
+
+```js
+el.onclick = eve.f("click", 1, 2);
+eve.on("click", function (a, b, c) {
+ console.log(a, b, c); // 1, 2, [event object]
+});
+```
+### Parameters
+- _event_ **string**
+ event name
+- _varargs_ **…**
+ and any other arguments
+
+**Returns:** **function** possible event handler function
+
+## eve.stop()
+Is used inside an event handler to stop the event, preventing any subsequent listeners from firing.
+
+
+## eve.nt([subname])
+Could be used inside event handler to figure out actual name of the event.
+
+### Parameters
+- _subname_ **string**
+ subname of the event
+
+**Returns:** **string** name of the event, if `subname` is not specified
+or
+
+**Returns:** **boolean** `true`, if current event’s name contains `subname`
+
+## eve.nts()
+Could be used inside event handler to figure out actual name of the event.
+
+**Returns:** **array** names of the event
+
+## eve.off(name, f)
+Removes given function from the list of event listeners assigned to given name.
+If no arguments specified all the events will be cleared.
+
+### Parameters
+- _name_ **string**
+ name of the event, dot (`.`) or slash (`/`) separated, with optional wildcards
+- _f_ **function**
+ event handler function
+
+
+## eve.unbind()
+See eve.off
+
+
+## eve.once(name, f)
+Binds given event handler with a given name to only run once then unbind itself.
+
+```js
+eve.once("login", f);
+eve("login"); // triggers f
+eve("login"); // no listeners
+```
+Use eve to trigger the listener.
+
+### Parameters
+- _name_ **string**
+ name of the event, dot (`.`) or slash (`/`) separated, with optional wildcards
+- _f_ **function**
+ event handler function
+
+**Returns:** **function** same return function as eve.on
+
+## eve.version()
+Current version of the library.
