## Options Well, let's go deeper

### Tour options

    var tour = new Tour({
      name: "tour",
      container: "body",
      keyboard: true,
      storage: window.localStorage,
      debug: false,
      backdrop: false,
      redirect: true,
      orphan: false,
      duration: false,
      basePath: "",
      template: "<div class='popover tour'>
        <div class='arrow'></div>
        <h3 class='popover-title'></h3>
        <div class='popover-content'></div>
        <div class='popover-navigation'>
            <button class='btn btn-default' data-role='prev'>« Prev</button>
            <span data-role='separator'>|</span>
            <button class='btn btn-default' data-role='next'>Next »</button>
        </div>
        <button class='btn btn-default' data-role='end'>End tour</button>
        </nav>
      </div>",
      afterGetState: function(key, value) {},
      afterSetState: function(key, value) {},
      afterRemoveState: function(key, value) {},
      onStart: function(tour) {},
      onEnd: function(tour) {},
      onShow: function(tour) {},
      onShown: function(tour) {}
      onHide: function(tour) {},
      onHidden: function(tour) {},
      onNext: function(tour) {},
      onPrev: function(tour) {},
      onPause: function(tour, duration) {},
      onResume: function(tour, duration) {}
    });

Name | Type | Description | Default
--- | --- | --- | ---
name | String | This option is used to build the name of the storage item where the tour state is stored. You can initialize several tours with different names in the same page and application. | `'tour'`
container | String | Appends the step popover to a specific element. See Usage section of Popover. | `'body'`
keyboard | Boolean | This option set the left and right arrow navigation. | `true`

storage

Object

The storage system you want to use. could be the objects window.localStorage, window.sessionStorage or your own object.
You can set this option as `false` to disable storage persistence (the tour starts from beginning everytime the page is loaded).
Read more about DOM Storage interfaces.

`window.localStorage`

debug | Boolean | Set this option to true to have some useful informations printed in the console. | `false`
backdrop | Boolean | Show a dark backdrop behind the popover and its element, highlighting the current step. | `false`
redirect | Boolean|Function | Set a custom function to execute as redirect function. The default redirect relies on the traditional `document.location.href` | `true`
orphan | Boolean | Allow to show the step regardless whether its element is not set, is not present in the page or is hidden. The step is fixed positioned in the middle of the page. | `false`
duration NEW | Boolean|String | Set a expiration time for the steps. When the current step expires, the next step is automatically shown. See it as a sort of guided, automatized tour functionality. The value is specified in milliseconds | `false`
basePath | String | Specify a default base path prepended to the `path` option of every single step. Very useful if you need to reuse the same tour on different environments or sub-projects. | `''`

template

String|Function

String or function that returns a string of the HTML template for the popovers. If you pass a Function, two parameters are available: i is the position of step in the tour and step is the an object that contains all the other step options.
From version 0.5, the navigation template is included inside the template so you can easily rewrite it. However, Bootstrap Tour maps the previous, next and end logics to the elements which have the related `data-role` attribute. Therefore, you can also have multiple elements with the same `data-role` attribute.

    "<div class='popover tour'>
      <div class='arrow'></div>
      <h3 class='popover-title'></h3>
      <div class='popover-content'></div>
      <div class='popover-navigation'>
        <button class='btn btn-default' data-role='prev'>« Prev</button>
        <span data-role='separator'>|</span>
        <button class='btn btn-default' data-role='next'>Next »</button>
        <button class='btn btn-default' data-role='end'>End tour</button>
      </div>
    </div>"

afterGetState, afterSetState, afterRemoveState

Function

You may want to do something right after Bootstrap Tour read, write or remove the state. Just pass functions to these.
Your functions can have two parameters:

- key Contains the name of the state being saved. It can be `current_step` (for the state where the latest step the visitor viewed is saved) or `end` (for the state which is saved when the user complete the tour). Note that Bootstrap Tour prepends the key with `tour_` when saving the state.
- value The value of the state been saved. Can be the index of the current step if the key is `current_step`, or `yes` if the key is `end`.

A simple example if to send a post request to your server each time there is a change:

    var tour = new Tour({
      afterSetState: function(key, value) {
        $.post("/some/path", value);
      }
    });

`function(key, value) { }`

onStart | Function | Function to execute when the tour starts. | `function(tour) { }`
onEnd | Function | Function to execute when the tour ends. | `function(tour) { }`
onShow | Function | Function to execute right before each step is shown. | `function(tour) { }`
onShown | Function | Function to execute right after each step is shown. | `function(tour) { }`
onHide | Function | Function to execute right before each step is hidden. | `function(tour) { }`
onHidden | Function | Function to execute right after each step is hidden. | `function(tour) { }`
onNext | Function | Function to execute when next step is called. | `function(tour) { }`
onPrev | Function | Function to execute when prev step is called. | `function(tour) { }`
onPause NEW | Function | Function to execute when pause is called. The second argument refers to the remaining duration. | `function(tour, duration) { }`
onResume NEW | Function | Function to execute when resume is called. The second argument refers to the remaining duration. | `function(tour, duration) { }`

## Contributing Do you think we need help? You are totally right

Without your bug reports and pull requests, we are nothing. Make this plugin better!

### Grunt Usage

#### Install Dependencies

Files to be developed inside the project are located under `/src/`.

Compiled sources are then automatically put under `/build/` (and `/test/`).

#### Run main tasks (check `Gruntfile.coffee` for more infos)

    // Start a server and run the demo page
    grunt
    grunt run
    // Compile all sources
    grunt build
    // Compile all sources and run the tests
    grunt test
    // Automatically release a new version (see below for more details)
    grunt release

#### Automatically releasing

Releasing a new version is completely automated using the Grunt task `grunt release`.

    grunt release // patch release
    grunt release:minor // minor release
    grunt release:major // major release

#### Live reload

Running `grunt run` will start a small server on port `3000` and opens the browser to the webpage. It will also start watching for changes in the `index.coffee` which will trigger then live reloading of the page in the browser.

#### Run the tests

Tests are written using Jasmine and they run headlessly through PhantomJS.
Simply run `grunt test` or watch them with `grunt watch:test` (this will execute them automatically every time you change the specs).

You can also open the `_SpecRunner.html` (generated after you run `grunt test`) to run the tests in the browser.
