/**
 * Unobtrusive scripting adapter for jQuery
 *
 * Requires jQuery 1.6.0 or later.
 * https://github.com/rails/jquery-ujs

 * Uploading file using rails.js
 * =============================
 *
 * By default, browsers do not allow files to be uploaded via AJAX. As a result, if there are any non-blank file fields
 * in the remote form, this adapter aborts the AJAX submission and allows the form to submit through standard means.
 *
 * The `ajax:aborted:file` event allows you to bind your own handler to process the form submission however you wish.
 *
 * Ex:
 *     $('form').live('ajax:aborted:file', function(event, elements){
 *       // Implement own remote file-transfer handler here for non-blank file inputs passed in `elements`.
 *       // Returning false in this handler tells rails.js to disallow standard form submission
 *       return false;
 *     });
 *
 * The `ajax:aborted:file` event is fired when a file-type input is detected with a non-blank value.
 *
 * Third-party tools can use this hook to detect when an AJAX file upload is attempted, and then use
 * techniques like the iframe method to upload the file instead.
 *
 * Required fields in rails.js
 * ===========================
 *
 * If any blank required inputs (required="required") are detected in the remote form, the whole form submission
 * is canceled. Note that this is unlike file inputs, which still allow standard (non-AJAX) form submission.
 *
 * The `ajax:aborted:required` event allows you to bind your own handler to inform the user of blank required inputs.
 *
 * !! Note that Opera does not fire the form's submit event if there are blank required inputs, so this event may never
 *    get fired in Opera. This event is what causes other browsers to exhibit the same submit-aborting behavior.
 *
 * Ex:
 *     $('form').live('ajax:aborted:required', function(event, elements){
 *       // Returning false in this handler tells rails.js to submit the form anyway.
 *       // The blank required inputs are passed to this function in `elements`.
 *       return ! confirm("Would you like to submit the form with missing info?");
 *     });

window.Mercury = {

  // # Mercury Configuration
  config: {
    // ## Toolbars
    //
    // This is where you can customize the toolbars by adding or removing buttons, or changing them and their
    // behaviors.  Any top level object put here will create a new toolbar.  Buttons are simply nested inside the
    // toolbars, along with button groups.
    //
    // Some toolbars are custom (the snippetable toolbar for instance), and to denote that use _custom: true.  You can
    // then build the toolbar yourself with it's own behavior.
    //
    // Buttons can be grouped, and a button group is simply a way to wrap buttons for styling -- they can also handle
    // enabling or disabling all the buttons within it by using a context.  The table button group is a good example
    // of this.
    //
    // It's important to note that each of the button names (keys), in each toolbar object must be unique, regardless
    // of if it's in a button group, or nested, etc.  This is because styling is applied to them by name, and because
    // their name is used in the event that's fired when you click on them.
    //
    // Button format: `[label, description, {type: action, type: action, etc}]`
    //
    // ### The available button types are:
    //
    // - toggle:  toggles on or off when clicked, otherwise behaves like a button
    // - modal:   opens a modal window, expects the action to be one of:
    //   1. a string url
    //   2. a function that returns a string url
    // - panel:   opens a panel dialog, expects the action to be one of:
    //   1. a string url
    //   2. a function that returns a string url
    // - palette: opens a palette window, expects the action to be one of:
    //   1. a string url
    //   2. a function that returns a string url
    // - select:  opens a pulldown style window, expects the action to be one of:
    //   1. a string url
    //   2. a function that returns a string url
    // - context: calls a callback function, expects the action to be:
    //   1. a function that returns a boolean to highlight the button
    //   note: if a function isn't provided, the key will be passed to the contextHandler, in which case a default
    //         context will be used (for more info read the Contexts section below)
    // - mode:    toggle a given mode in the editor, expects the action to be:
    //   1. a string, denoting the name of the mode
    //   note: it's assumed that when a specific mode is turned on, all other modes will be turned off, which happens
    //         automatically, thus putting the editor into a specific "state"
    // - regions: allows buttons to be enabled/disabled based on what region type has focus, expects the action to be:
    //   1. an array of region types (eg. ['editable', 'markupable'])
    // - preload: allows some dialog views to be loaded when the button is created instead of on first open, expects:
    //   1. a boolean true / false
    //   note: this is only used by panels, selects, and palettes
    //
    // Separators are any "button" that's not an array, and are expected to be a string.  You can use two different
    // separator styles: line ('-'), and spacer (' ').

    // ## Hijacking Links & Forms
    //
    // Mercury will hijack links and forms that don't have a target set, or the target is set to _self and will set it
    // to _top.  This is because the target must be set properly for Mercury to not get in the way of some
    // functionality, like proper page loads on form submissions etc.  Mercury doesn't do this to links or forms that
    // are within editable regions because it doesn't want to impact the html that's saved.  With that being explained,
    // you can add classes to links or forms that you don't want this behavior added to.  Let's say you have links that
    // open a lightbox style window, and you don't want the targets of these to be set to _top.  You can add classes to
    // this array, and they will be ignored when the hijacking is applied.
    nonHijackableClasses: [],


    // ## Ajax and CSRF Headers
    //
    // Some server frameworks require that you provide a specific header for Ajax requests.  The values for these CSRF
    // tokens are typically stored in the rendered DOM.  By default, Mercury will look for the Rails specific meta tag,
    // and provide the X-CSRF-Token header on Ajax requests, but you can modify this configuration if the system you're
    // using doesn't follow the same standard.
    csrfSelector: 'meta[name="csrf-token"]',
    csrfHeader: 'X-CSRF-Token',


    // ## Pasting & Sanitizing
    //
    // When pasting content into Mercury it may sometimes contain HTML tags and attributes.  This markup is used to
    // style the content and makes the pasted content look (and behave) the same as the original content.  This can be a
    // desired feature or an annoyance, so you can enable various sanitizing methods to clean the content when it's
    // pasted.
    //
    // ### Sanitizing options:
    // - false: no sanitizing is done, the content is pasted the exact same as it was copied by the user
    // - 'whitelist': content is cleaned using the settings specified in the tag white list (described below)
    // - 'text': all html is stripped before pasting, leaving only the raw text
    //
    // ### Using the whitelist configuration
    //
    // The white list allows you to specify tags and attributes that are allowed when pasting content.  Each item in
    // this object should contain the allowed tag, and an array of attributes that are allowed on that tag.  If the
    // allowed attributes array is empty, all attributes will be removed.  If a tag is not present in this list, it will
    // be removed, but without removing any of the text or tags inside it.
    //
    // **Note:** Content is *always* sanitized if looks like it's from MS Word or similar editors regardless of this
    // configuration.
    pasting: {
      sanitize: 'whitelist',
      whitelist: {
        h1:     [],

    // ## Snippet Options and Preview
    //
    // When a user drags a snippet onto the page they'll be prompted to enter options for the given snippet.  The server
    // is expected to respond with a form.  Once the user submits this form, an Ajax request is sent to the server with
    // the options provided; this preview request is expected to respond with the rendered markup for the snippet.
    //
    // Name will be replaced with the snippet name (eg. example)
    snippets: {
      method: 'POST',
      optionsUrl: '/mercury/snippets/:name/options.html',
      previewUrl: '/mercury/snippets/:name/preview.html'
      },


    // ## Image Uploading
    //
    // If you drag images (while pressing shift) from your desktop into regions that support it, it will be uploaded
    // to the server and inserted into the region.  This configuration allows you to specify if you want to
    // disable/enable this feature, the accepted mime-types, file size restrictions, and other things related to
    // uploading.  You can optionally provide a handler function that takes the response from the server and returns an
    // object: {image: {url: '[your provided url]'}
    //
    // **Note:** Image uploading is only supported in some region types, and some browsers.
    uploading: {
      enabled: true,
      allowedMimeTypes: ['image/jpeg', 'image/gif', 'image/png'],
      maxFileSize: 1235242880,
      inputName: 'image[image]',
      url: '/images',
      handler: false
      },


    // ## Behaviors
    //
    // Behaviors are used to change the default behaviors of a given region type when a given button is clicked.  For
    // example, you may prefer to add HR tags using an HR wrapped within a div with a classname (for styling).  You
    // can add your own complex behaviors here.
    //
    // You can see how the behavior matches up directly with the button names.  It's also important to note that the
    // callback functions are executed within the scope of the given region, so you have access to all it's methods.
    // Here's some examples to help you get started.
    behaviors: {
      //foreColor: function(selection, options) { selection.wrap('<span style="color:' + options.value.toHex() + '">', true) },
      htmlEditor: function() { Mercury.modal('/mercury/modals/htmleditor.html', { title: 'HTML Editor', fullHeight: true, handler: 'htmlEditor' }); }
      },


    // ## Contexts
    //
    // Contexts are used callback functions used for highlighting and disabling/enabling buttons and buttongroups.
    // When the cursor enters an element within an html region for instance we want to disable or highlight buttons
    // based on the properties of the given node.  You can see some examples of contexts in:
    //
    // Mercury.Toolbar.Button.contexts
    // and
    // Mercury.Toolbar.ButtonGroup.contexts

    
    // ## Region Class
    //
    // Mercury identifies editable regions by a region class.  This class has to be added in your HTML in advance, and
    // is the only real Mercury code/naming exposed in the implementation of Mercury.  To allow this to be as
    // configurable as possible, you can set the name of the class here.  When switching to preview mode, this
    // configuration is used to generate a class to indicate that Mercury is in preview mode -- which will be this
    // class with '-preview' appended (so, mercury-region-preview by default)
    regionClass: 'mercury-region',

    
    // ## Styles
    //
    // Mercury tries to stay as much out of your code as possible, but because regions appear within your document we
    // need to include a few styles to indicate regions, as well as the different states of them (eg. focused).  These
    // styles are injected into your document, and as simple as they might be, you may want to change them.  You can do
    // so here.  {{regionClass}} will be automatically replaced with whatever you have set in the regionClass
    // configuration directive.
    injectedStyles: '' +
      '.{{regionClass}} { min-height: 10px; outline: 1px dotted #09F } ' +
      '.{{regionClass}}:focus, .{{regionClass}}.focus { outline: none; -webkit-box-shadow: 0 0 10px #09F, 0 0 1px #045; box-shadow: 0 0 10px #09F, 0 0 1px #045 }' +
      '.{{regionClass}}:after { content: "."; display: block; visibility: hidden; clear: both; height: 0; overflow: hidden; }' +
      '.{{regionClass}} table, .{{regionClass}} td, .{{regionClass}} th { border: 1px dotted red; min-width: 6px; }' +
      '.mercury-textarea { border: 0; box-sizing: border-box; -moz-box-sizing: border-box; -webkit-box-sizing: border-box; resize: none; }' +
      '.mercury-textarea:focus { outline: none; }'
  },

  // ## Silent Mode
  //
  // Turning silent mode on will disable asking about unsaved changes before leaving the page.
  silent: false,

  // ## Debug Mode
  //
  // Turning debug mode on will log events and other various things (using console.debug if available).
  debug: false

};

// The mercury:loaded event is provided in case you want to override default Mercury Editor behavior.  It will fire
// directly after the Mercury scripts have loaded, but before anything has been initialized.  It's a good place to add
// or change functionality.
jQuery(window).bind('mercury:loaded', function() {
  //Mercury.PageEditor.prototype.iframeSrc = function(url) { return '/testing'; }
});


$(window).bind('mercury:ready', function() {
  var link = $('#mercury_iframe').contents().find('#edit_link');

//
// Wherever possible, Showdown is a straight, line-by-line port
// of the Perl version of Markdown.
//
// This is not a normal parser design; it's basically just a
// series of string substitutions.  It's hard to read and
// maintain this way,  but keeping Showdown close to the original
// design makes it easier to port new features.
//
// More importantly, Showdown behaves like markdown.pl in most
// edge cases.  So web applications can do client-side preview
// in Javascript, and then build identical HTML on the server.
//
// This port needs the new RegExp functionality of ECMA 262,
// 3rd Edition (i.e. Javascript 1.5).  Most modern web browsers
// should do fine.  Even with the new regular expression features,
// We do a lot of work to emulate Perl's regex functionality.
// The tricky changes in this file mostly have the "attacklab:"
// label.  Major or self-explanatory changes don't.
//
// Smart diff tools like Araxis Merge will be able to match up
// this file with markdown.pl in a useful way.  A little tweaking
// helps: in a copy of markdown.pl, replace "#" with "//" and
// replace "$text" with "text".  Be sure to ignore whitespace
// and line endings.
//


//
// Showdown usage:
//
//   var text = "Markdown *rocks*.";
//
//   var converter = new Showdown.converter();
//   var html = converter.makeHtml(text);
//
//   alert(html);
//
// Note: move the sample code to the bottom of this
// file before uncommenting it.

//   <http://www.attacklab.net/>
//

//
// Wherever possible, Showdown is a straight, line-by-line port
// of the Perl version of Markdown.
//
// This is not a normal parser design; it's basically just a
// series of string substitutions.  It's hard to read and
// maintain this way,  but keeping Showdown close to the original
// design makes it easier to port new features.
//
// More importantly, Showdown behaves like markdown.pl in most
// edge cases.  So web applications can do client-side preview
// in Javascript, and then build identical HTML on the server.
//
// This port needs the new RegExp functionality of ECMA 262,
// 3rd Edition (i.e. Javascript 1.5).  Most modern web browsers
// should do fine.  Even with the new regular expression features,
// We do a lot of work to emulate Perl's regex functionality.
// The tricky changes in this file mostly have the "attacklab:"
// label.  Major or self-explanatory changes don't.
//
// Smart diff tools like Araxis Merge will be able to match up
// this file with markdown.pl in a useful way.  A little tweaking
// helps: in a copy of markdown.pl, replace "#" with "//" and
// replace "$text" with "text".  Be sure to ignore whitespace
// and line endings.
//


//
// Showdown usage:
//
//   var text = "Markdown *rocks*.";
//
//   var converter = new Attacklab.showdown.converter();
//   var html = converter.makeHtml(text);
//
//   alert(html);
//
// Note: move the sample code to the bottom of this
// file before uncommenting it.
