Angular-wizard is a component that will make it easy for you to create wizards in your app. You can check a running example of the wizard [by clicking here](http://mgonto.github.io/angular-wizard/)

# How do I add this to my project?
You can download this by:

* Using bower and running `bower install angular-wizard`
* Using npm and running `npm install angular-wizard`
* Downloading it manually by getting the files from the dist folder
* Using JsDelivr CDN files:

````html
<!-- Use LATEST folder to always get the latest version-->
<script type="text/javascript" src="http://cdn.jsdelivr.net/angular.wizard/latest/angular-wizard.min.js"></script>
<link rel="stylesheet" type="text/css" href="http://cdn.jsdelivr.net/angular.wizard/latest/angular-wizard.min.css">

<!-- Or use TAG number for specific version -->
<script type="text/javascript" src="http://cdn.jsdelivr.net/angular.wizard/0.6.1/angular-wizard.min.js"></script>
<link rel="stylesheet" type="text/css" href="http://cdn.jsdelivr.net/angular.wizard/0.6.1/angular-wizard.min.css">
````

The dist folder contains the following files:

* JS files needed for the directives and services
* CSS files with default styles for the directive
* LESS file with styles for the directive. If you have less in your project, I recommend using the less instead of the CSS since it has variables to configure Wizard colors.

# Dependencies
Angular-wizard depends on Angular.

# Starter Guide

## First example

The first thing we need to do is add a dependency to angular-wizard module which is called `mgo-angular-wizard`.

We can do this simply by doing: 

````js
angular.module('your-app', ['mgo-angular-wizard']);
````

Now, in some HTML for a controller, you can just add a wizard as follows:

````html
<wizard on-finish="finishedWizard()"> 
    <wz-step title="Starting">
        <h1>This is the first step</h1>
        <p>Here you can use whatever you want. You can use other directives, binding, etc.</p>
        <input type="submit" wz-next value="Continue" />
    </wz-step>
    <wz-step title="Continuing">
        <h1>Continuing</h1>
        <p>You have continued here!</p>
        <input type="submit" wz-next value="Go on" />
    </wz-step>
    <wz-step title="More steps">
        <p>Even more steps!!</p>
        <input type="submit" wz-next value="Finish now" />
    </wz-step>
</wizard>
````

This will look like the following when you're in the second step:

Let's go step by step to see how this works.

1) You need to declare a master `wizard` directive. This wizard directive, has the following options as attributes:
* **on-finish**: Here you can put a function to be called when the wizard is finished. The syntax here is very similar to `ng-click`
* **name**: The name of the wizard. By default, it's called "Default wizard". It's used for the `WizardHandler` which we'll explain later.
* **edit-mode**: If set to true, this will set the wizard as edit mode. Edit mode means that all steps have been completed and the user can now navigate to and modify any step. Defaults to false.
* **hide-indicators**: If set to true, the indicators in the bottom of the page showing the current page and allowing navigation for the wizard will be hidden. Defaults to false.
* **current-step**: You need to set here a property from your scope (similar to `ng-model`) and that property will always have the name of the current step being shown on the screen.
* **template**: Path to a custom template.

2) Inside the wizard, we can have as many steps as we want. Each step MUST have a title which is going to be used to identify it. Inside each step, we can put whatever we want. Other directives, bindings, controls, forms, etc.  Each step can have the following attributes (we will go into detail on each further below):
* **wz-title:** A unique title used for identifying each step.
* **canenter**
* **canexit**
* **wz-disabled**
* **description:** A description available to use in each step's UI.
* **wz-data** Data you wish to make available to the steps scope.

3) Inside the step, we now see a button which has a `wz-next` attribute. That means that clicking that button will send the user to the next step of wizard. Similar to `wz-next`, we have the following attributes:
* **wz-previous**: Goes to the previous step
* **wz-cancel**: Goes back to the first step
* **wz-finish**: Finishes the wizard and calls the on-finish later on. It's important to note that if we're in the last step and we put `wz-next` it'll be the same as putting `wz-finish` as the wizard will know we're at the last screen.
* **wz-reset**: This will reset the wizard meaning bring the user to the first step and reset each step to being incomplete.

All of this attributes can receive an optional function to be called before changing the step. Something like:

````html
<input type="button" wz-next="setMode(mode)" value="Next" />
````

In this case, the `setMode` function will be called before going to the next step.

## Wizard Dynamic Steps
A step can be conditionally disabled and may change at any time either adding it or removing it from the wizard step flow.

 **Example**
 
HTML
````html
<wizard on-finish="finishedWizard()"> 
    <wz-step title="Starting" wz-disabled="{{disabled}}">
        <h1>This is the first step</h1>
        <p>Here you can use whatever you want. You can use other directives, binding, etc.</p>
        <input type="submit" wz-next value="Continue" />
    </wz-step>
    <wz-step title="Continuing">
        <h1>Continuing</h1>
        <p>You have continued here!</p>
        <input type="submit" wz-next value="Go on" />
    </wz-step>
    <wz-step title="More steps">
        <p>Even more steps!!</p>
        <input type="submit" wz-next value="Finish now" />
    </wz-step>
</wizard>
````
Controller
````javascript
//this will cause the step to be hidden
$scope.disabled = 'true';
````


## Wizard Step Validation
The wzStep directive has the following options as attributes:
* **canexit**: Here you can reference a function from your controller.  If this attribute is listed the function must return true in order for the wizard to move to the next step. Promises are supported but must resolve with a thruthy value.  If it is ommitted no validation will be required.
* **canenter**: Here you can reference a function from your controller.  If this attribute is listed the function must return true in order for the wizard to move into this step.   Promises are supported but must resolve with a thruthy value.  If it is ommitted no validation will be required.

 **Example**
 
HTML
````html
<wizard on-finish="finishedWizard()"> 
    <wz-step title="Starting" canexit="exitValidation">
        <h1>This is the first step</h1>
        <p>Here you can use whatever you want. You can use other directives, binding, etc.</p>
        <input type="submit" wz-next value="Continue" />
    </wz-step>
    <wz-step title="Continuing" canenter="enterValidation">
        <h1>Continuing</h1>
        <p>You have continued here!</p>
        <input type="submit" wz-next value="Go on" />
    </wz-step>
    <wz-step title="More steps">
        <p>Even more steps!!</p>
        <input type="submit" wz-next value="Finish now" />
    </wz-step>
</wizard>
````
Controller
````javascript
$scope.enterValidation = function(){
    return true;
};

$scope.exitValidation = function(){
    return true;
};
//example using context object
$scope.exitValidation = function(context){
    return context.firstName === "Jacob";
}
//example using promises
$scope.exitValidation = function(){
    var d = $q.defer()
    $timeout(function(){
        return d.resolve(true);
    }, 2000);
    return d.promise;
}
````
If a step requires information from a previous step to populate itself you can access this information through the `context` object.  The context object is automatically passed in as an argument into your canexit and canenter methods.  You can access the context objext from your controller via: `WizardHandler.wizard().context`

## Manipulating the wizard from a service
There are some times where we actually want to manipulate the wizard from the controller instead of from the HTML.

For those cases, we can inject the `WizardHandler` to our controller.

The main function of this service is the `wizard(name)` which will let you get the wizard to manipulate it. If you have just one wizard in the screen and you didn't set a name to it, you can just call it as `wizard()`. Let's see an example:

````html
<wz-step title="Cool step">
    <input type="submit" ng-click="changeLabelAndGoNext()" />
</wz-step>
````

````js
// In your controller
$scope.changeLabelAndGoNext = function() {
    $scope.model.label = "Hola Gonto";
    WizardHandler.wizard().next();
}
````

In this case, we're changing a label and moving forward on the steps.
The functions available in the `wizard()` are:
* **next**: Goes to the next step.
* **previous**: Goes to the previous step.
* **cancel**: Goes to the previous step.
* **reset**: Goes to the first step and resets all steps to incomplete.
* **finish**: Finishes the wizard.
* **goTo(number|title)**: This goes to the indicated step. It can receive either the number of the step (starting from 0) or the title of the step to go to.
* **currentStepNumber()**: This returns a Number which is the current step number you are on.
* **currentStepTitle()**: This returns a String which is the title of the step you are on.
* **currentStepDescription()**: This returns a String which is the description of the step you are on.
* **currentStep()**: This returns an Object which is the current step you are on.
* **totalStepCount()**: This returns an Number which is the total number of **enabled** steps.
* **getEnabledSteps()**: This returns an Array which is the **enabled** steps.

## Navigation bar

Any changed you wish to make to the navigation bar can be done by overwritting the CSS.  Because everyone wants the navigation bar in a different location and in a different style we have provided a default which you can change via your own HTML and CSS. The navigation bar shown below works in the following way:

* Completed steps are painted as green
* Current step is painted as dark grey
* Future step is painted as light grey
* Editing step (Modifying a step already completed in the past) is painted as red
* You can click in any completed step to go back to that step. You can't click in the current step nor in the future ones unless you've already completed a future step before (for example in EditMode all steps are completed by default)

### Color Definitions
All of those colors are variables in the `angular-wizard.less`. You can easily change them by importing the `angular-wizard.less` file into your own less file(s) and change the variables.
The available variables are:
* @wz-color-default
* @wz-color-done
* @wz-color-current
* @wz-color-editing
