## Date formatting

#### String formatter

NB. This is not very robust at all - use at your own risk! Needs a better implementation.

| Token | Desc                   | Example     |
|-------|------------------------|-------------|
| d     | day                    | 1           |
| dd    | 0 prefixed day         | 01          |
| D     | abbr day               | Mon         |
| su    | date suffix            | st, nd, rd  |
| M     | month number (1 based) | 1 (for Jan) |
| MM    | 0 prefixed month       | 01          |
| MMM   | abbreviated month name | Jan         |
| MMMM  | month name             | January     |
| yy    | two digit year         | 16          |
| yyyy  | four digit year        | 2016        |

#### Function formatter

Delegates date formatting to provided function.
Function will be called with date and it has to return formated date as a string.
This allow us to use moment, date-fns, globalize or any other library to format date.

``` html
<script>
  methods: {
    customFormatter(date) {
      return moment(date).format('MMMM Do YYYY, h:mm:ss a');
    }
  }
</script>
<datepicker :format="customFormatter"></datepicker>
```

## Disabled Dates
Dates can be disabled in a number of ways.

``` html
<script>
var state = {
  disabledDates: {
    to: new Date(2016, 0, 5), // Disable all dates up to specific date
    from: new Date(2016, 0, 26), // Disable all dates after specific date
    days: [6, 0], // Disable Saturday's and Sunday's
    daysOfMonth: [29, 30, 31], // Disable 29th, 30th and 31st of each month
    dates: [ // Disable an array of dates
      new Date(2016, 9, 16),
      new Date(2016, 9, 17),
      new Date(2016, 9, 18)
    ],
    ranges: [{ // Disable dates in given ranges (exclusive).
      from: new Date(2016, 11, 25),
      to: new Date(2016, 11, 30)
    }, {
      from: new Date(2017, 1, 12),
      to: new Date(2017, 2, 25)
    }],
    // a custom function that returns true if the date is disabled
    // this can be used for wiring you own logic to disable a date if none
    // of the above conditions serve your purpose
    // this function should accept a date and return true if is disabled
    customPredictor: function(date) {
      // disables the date if it is a multiple of 5
      if(date.getDate() % 5 == 0){
        return true
      }
    }
  }
}
</script>
<datepicker :disabled-dates="state.disabledDates"></datepicker>
```

## Highlighted Dates
Dates can be highlighted (e.g. for marking an appointment) in a number of ways. Important:
By default disabled dates are ignored, to highlight disabled dates set the `includeDisabled`
property to `true`. Note: Both `to` and `from` properties are required to define a range of
dates to highlight.

``` html
<script>
var state = {
  highlighted: {
    to: new Date(2016, 0, 5), // Highlight all dates up to specific date
    from: new Date(2016, 0, 26), // Highlight all dates after specific date
    days: [6, 0], // Highlight Saturday's and Sunday's
    daysOfMonth: [15, 20, 31], // Highlight 15th, 20th and 31st of each month
    dates: [ // Highlight an array of dates
      new Date(2016, 9, 16),
      new Date(2016, 9, 17),
      new Date(2016, 9, 18)
    ],
    // a custom function that returns true of the date is highlighted
    // this can be used for wiring you own logic to highlight a date if none
    // of the above conditions serve your purpose
    // this function should accept a date and return true if is highlighted
    customPredictor: function(date) {
      // highlights the date if it is a multiple of 4
      if(date.getDate() % 4 == 0){
        return true
      }
    },
    includeDisabled: true // Highlight disabled dates
  }
}
</script>
<datepicker :highlighted="state.highlighted"></datepicker>
```
## Slots

Slots will help you customize content.  .

#### beforeCalendarHeader

Sometimes you need to show custom content before the calendar header. For such cases you can use the named slot `beforeCalendarHeader`.

An example would be to use bootstrap's `input-group-prepend` and `input-group-append`
to show some custom text:
``` html
<datepicker :bootstrap-styling="true">
  <div slot="beforeCalendarHeader" class="calender-header">
    Choose a Date
  </div>
</datepicker>
```

#### afterDateInput

To implement some custom styling (for instance to add an animated placeholder) on DateInput, you might need to add elements as DateInput siblings. Slot named
`afterDateInput` allows you to do that:

``` html
<datepicker>
  <span slot="afterDateInput" class="animated-placeholder">
    Choose a Date
  </span>
</datepicker>
```
