 ## [1.0.0](https://github.com/showdownjs/showdown/compare/0.3.4...1.0.0) (2015-05-27)

 ### Release Information
 This is a major code refactor with some big changes such as:
  - showdown.js file was split in several files, called sub-parsers. This should improve code maintainability.
  - angular integration was removed from core and move to its own repository, similar to what was done with extensions
  - A new extension registering system is on the "cooks" that should reduce errors when using extensions. The old mechanism
  is kept so old extensions should be compatible.

 ### Bug Fixes

 * **extensions:** support for old extension loading mechanism ([95ed7c68](http://github.com/showdownjs/showdown/commit/95ed7c68))
 * **helpers:** fix wrong function call 'escapeCharacters' due to old strayed code ([18ba4e75](http://github.com/showdownjs/showdown/commit/18ba4e75))
 * **showdown.js:**
  - fix showdown extension loader ([a38c76d2](http://github.com/showdownjs/showdown/commit/a38c76d2)),

  - add unique id prefix and suffix to headers ([c367a4b9](http://github.com/showdownjs/showdown/commit/c367a4b9), closes [#81](http://github.com/showdownjs/showdown/issues/81), [#82](http://github.com/showdownjs/showdown/issues/82))
 * **options.omitExtraWLInCodeBlocks:** fix for options.omitExtraWLInCodeBlocks only applying in gitHub flavoured code b ([e6f40e19](http://github.com/showdownjs/showdown/commit/e6f40e19))
 * **showdown:** fix for options merging into globalOptions ([ddd6011d](http://github.com/showdownjs/showdown/commit/ddd6011d), closes [#153](http://github.com/showdownjs/showdown/issues/153))

 ### Features

 * **registerExtension():** new extension loading mechanism. Now extensions can be registered using this function.
  The system, however, is not final and will probably be changed until the final version([0fd10cb] (http://github.com/showdownjs/showdown/commit/0fd10cb))
 * **allowBlockIndents:** indented inline block elements can now be parsed as markdown ([f6326b84](http://github.com/showdownjs/showdown/commit/f6326b84))
 * **omitExtraWLInCodeBlocks:**  add option to omit extra newline at the end of codeblocks ([141e3f5](http://github.com/showdownjs/showdown/commit/141e3f5))
 * **prefixHeaderId:** add options to prefix header ids to prevent id clash ([141e3f5](http://github.com/showdownjs/showdown/commit/141e3f5))
 * **Converter.options:** add getOption(), setOption() and getOptions() to Converter object ([db6f79b0](http://github.com/showdownjs/showdown/commit/db6f79b0))

 ### Breaking Changes
 * **NAMESPACE:** showdown's namespace changed.

   To migrate your code you should update all references to `Showdown` with `showdown`.

 * **Converter:** converter reference changed from `converter` to `Converter`.

   To migrate you should update all references to `Showdown.converter` with `showdown.Converter`

 * **angular:** angular integration was removed from core and now lives in it's own [repository](http://github.com/showdownjs/angular/).

   If you're using angular integration, you should install ng-showdown. Ex: `bower install ng-showdown`

 * **extensions:** showdown extensions were removed from core package and now live in their own repository. See the [project's github page](https://github.com/showdownjs) for available extensions

 Contributing
 ============

 If you wish to contribute please read the following quick guide.

 # Issues (bug reporting)
 Generally, bug reports should be in the following format:

 1. Description (Brief description of the problem)
 2. Input (input that is causing problems)
 3. Expected Output (Output that is expected)
 4. Actual Output (Actual showdown output)

 ex:

 **Description:**
 Double asterisks do not parse as bold

 **Input:**
    
    hello **world**!
     
 **Expected output:**

    <p>hello <b>world</b>!

 **Actual Output:**

    <p>hello **world**!</p>



 # Want a Feature?
 You can request a new feature by submitting an issue. If you would like to implement a new feature feel free to issue a
 Pull Request.


 # Pull requests (PRs)
 PRs are awesome. However, before you submit your pull request consider the following guidelines:

 - Search GitHub for an open or closed Pull Request that relates to your submission. You don't want to duplicate effort.
 - When issuing PRs that change code, make your changes in a new git branch based on develop:

   ```bash
   git checkout -b my-fix-branch develop
   ```

 - Run the full test suite before submitting and make sure all tests pass (obviously =P).
 - Try to follow our [**coding style rules**](https://github.com/showdownjs/code-style/blob/master/README.md).
   Breaking them prevents the PR to pass the tests.
 - Refrain from fixing multiple issues in the same pull request. It's preferable to open multiple small PRs instead of one
   hard to review big one. Also, don't reuse old forks (or PRs) to fix new issues.
 - If the PR introduces a new feature or fixes an issue, please add the appropriate test case.
 - We use commit notes to generate the changelog. It's extremely helpful if your commit messages adhere to the
 [**AngularJS Git Commit Guidelines**](https://github.com/showdownjs/code-style/blob/master/README.md#commit-message-convention).
 - If we suggest changes then:
   - Make the required updates.
   - Re-run the Angular test suite to ensure tests are still passing.
   - Rebase your branch and force push to your GitHub repository (this will update your Pull Request):

   ```bash
   git rebase develop -i
   git push origin my-fix-branch -f
   ```
 - After your pull request is merged, you can safely delete your branch.

 If you have time to contribute to this project, we feel obliged that you get credit for it.
 These rules enable us to review your PR faster and will give you appropriate credit in your GitHub profile.
 We thank you in advance for your contribution!

 - [and some others...](https://www.npmjs.com/browse/depended/showdown)

 ## Installation

 ### Download tarball

 You can download the latest release tarball directly from [releases][releases]

 ### Bower

    bower install showdown

 ### npm (server-side)

    npm install showdown

 ### NuGet package

    PM> Install-Package showdownjs

 The NuGet Packages can be [found here](https://www.nuget.org/packages/showdownjs/).

 ### CDN

 You can also use one of several CDNs available: 

 * jsDelivr

        https://cdn.jsdelivr.net/npm/showdown@<version tag>/dist/showdown.min.js

 * cdnjs

        https://cdnjs.cloudflare.com/ajax/libs/showdown/<version tag>/showdown.min.js

 * unpkg
       
        https://unpkg.com/showdown/dist/showdown.min.js

 *Note*: replace `<version tag>` with an actual full length version you're interested in e.g. `1.9.0`
 ## Browser Compatibility

 Showdown has been tested successfully with:

  * Firefox 1.5 and 2.0
  * Chrome 12.0
  * Internet Explorer 6 and 7
  * Safari 2.0.4
  * Opera 8.54 and 9.10
  * Netscape 8.1.2
  * Konqueror 3.5.4

 In theory, Showdown will work in any browser that supports ECMA 262 3rd Edition (JavaScript 1.5).
 The converter itself might even work in things that aren't web browsers, like Acrobat.  No promises.


 ## Node compatibility

 Showdown has been tested with node 0.8 and 0.10. However, it should work with previous versions, such as node 0.6.


 ## Legacy version

 If you're looking for showdown v<1.0.0, you can find it in the [**legacy branch**][legacy-branch].

 ## Changelog

 You can check the full [changelog][changelog]

 ## Extended documentation
 Check our [wiki pages][wiki] for examples and a more in-depth documentation.


 ## Quick Example

 ### Node

 ```js
 var showdown  = require('showdown'),
    converter = new showdown.Converter(),
    text      = '# hello, markdown!',
    html      = converter.makeHtml(text);
 ```

 ### Browser

 ```js
 var converter = new showdown.Converter(),
    text      = '# hello, markdown!',
    html      = converter.makeHtml(text);
 ```

 ### Output 

 Both examples should output...

 ```html
    <h1 id="hellomarkdown">hello, markdown!</h1>
 ```

 ## Options

 You can change some of showdown's default behavior through options. 

 ### Setting options

 Options can be set:

 #### Globally

 Setting a "global" option affects all instances of showdown

 ```js
 showdown.setOption('optionKey', 'value');
 ```

 #### Locally
 Setting a "local" option only affects the specified Converter object. 
 Local options can be set:

 * **through the constructor**
    ```js
    var converter = new showdown.Converter({optionKey: 'value'});
    ```

 * **through the setOption() method**
    ```js
    var converter = new showdown.Converter();
    converter.setOption('optionKey', 'value');
    ```

 ### Getting an option

 Showdown provides 2 methods (both local and global) to retrieve previous set options.

 #### getOption()

 ```js
 // Global
 var myOption = showdown.getOption('optionKey');

 //Local
 var myOption = converter.getOption('optionKey');
 ```

 #### getOptions()

 ```js
 // Global
 var showdownGlobalOptions = showdown.getOptions();

 //Local
 var thisConverterSpecificOptions = converter.getOptions();
 ```

 ### Retrieve the default options

 You can get showdown's default options with:
 ```js
 var defaultOptions = showdown.getDefaultOptions();
 ```

 ### Valid Options

 * **omitExtraWLInCodeBlocks**: (boolean) [default false] Omit the trailing newline in a code block. Ex:
   
    This:
    ```html
    <code><pre>var foo = 'bar';
    </pre></code>
    ```
    Becomes this:
    ```html
    <code><pre>var foo = 'bar';</pre></code>
    ```

 * **noHeaderId**: (boolean) [default false] Disable the automatic generation of header ids.
   Setting to true overrides **prefixHeaderId**

 * **customizedHeaderId**: (boolean) [default false] Use text in curly braces as header id. **(since v1.7.0)**
   Example:
   ```
   ## Sample header {real-id}     will use real-id as id
   ```

 * **ghCompatibleHeaderId**: (boolean) [default false] Generate header ids compatible with github style
   (spaces are replaced with dashes and a bunch of non alphanumeric chars are removed) **(since v1.5.5)**

 * **prefixHeaderId**: (string/boolean) [default false] Add a prefix to the generated header ids.
   Passing a string will prefix that string to the header id. Setting to `true` will add a generic 'section' prefix.

 * **rawPrefixHeaderId**: (boolean) [default false] Setting this option to true will prevent showdown from modifying the prefix.
   This might result in malformed IDs (if, for instance, the " char is used in the prefix).
   Has no effect if prefixHeaderId is set to false. **(since v 1.7.3)**

 * **rawHeaderId**: (boolean) [default false] Remove only spaces, ' and " from generated header ids (including prefixes),
    replacing them with dashes (-). WARNING: This might result in malformed ids **(since v1.7.3)**
 
 * **headerLevelStart**: (integer) [default 1] Set the header starting level. For instance, setting this to 3 means that

    ```md
    # foo
    ```
    will be parsed as 
    
    ```html
    <h3>foo</h3>
    ```

 * **parseImgDimensions**: (boolean) [default false] Enable support for setting image dimensions from within markdown syntax.
   Examples:
   ```
   ![foo](foo.jpg =100x80)     simple, assumes units are in px
   ![bar](bar.jpg =100x*)      sets the height to "auto"
   ![baz](baz.jpg =80%x5em)  Image with width of 80% and height of 5em
   ```

 * **simplifiedAutoLink**: (boolean) [default false] Turning this option on will enable automatic linking to urls.
   This means that:

   ```md
   some text www.google.com
   ```
   will be parsed as 
   ```html
   <p>some text <a href="www.google.com">www.google.com</a>
   ```
 
 * ~~**excludeTrailingPunctuationFromURLs**: (boolean) [default false] This option excludes trailing punctuation from autolinking urls.
   Punctuation excluded: `. !  ? ( )`. Only applies if **simplifiedAutoLink** option is set to `true`.~~
   
 * **literalMidWordUnderscores**: (boolean) [default false] Turning this on will stop showdown from interpreting
   underscores in the middle of words as `<em>` and `<strong>` and instead treat them as literal underscores.

   Example:
   
   ```md
   some text with__underscores__in middle
   ```
   will be parsed as
   ```html
   <p>some text with__underscores__in middle</p>
   ```

 * ~~**literalMidWordAsterisks**: (boolean) [default false] Turning this on will stop showdown from interpreting asterisks
   in the middle of words as `<em>` and `<strong>` and instead treat them as literal asterisks.~~
   
 * **strikethrough**: (boolean) [default false] Enable support for strikethrough syntax.
   `~~strikethrough~~` as `<del>strikethrough</del>`
   
 * **tables**: (boolean) [default false] Enable support for tables syntax. Example:
    
   ```md
   | h1    |    h2   |      h3 |
   |:------|:-------:|--------:|
   | 100   | [a][1]  | ![b][2] |
   | *foo* | **bar** | ~~baz~~ |
   ```
   
   See the wiki for more info

 * **tablesHeaderId**: (boolean) [default false] If enabled adds an id property to table headers tags.

 * **ghCodeBlocks**: (boolean) [default true] Enable support for GFM code block style.

 * **tasklists**: (boolean) [default false] Enable support for GFM tasklists. Example:
 
   ```md
    - [x] This task is done
    - [ ] This is still pending
   ```
 * **smoothLivePreview**: (boolean) [default false] Prevents weird effects in live previews due to incomplete input
 
 * **smartIndentationFix**: (boolean) [default false] Tries to smartly fix indentation problems related to es6 template
   strings in the midst of indented code.

 * **disableForced4SpacesIndentedSublists**: (boolean) [default false] Disables the requirement of indenting sublists
   by 4 spaces for them to be nested, effectively reverting to the old behavior where 2 or 3 spaces were enough.
   **(since v1.5.0)**
 
 * **simpleLineBreaks**: (boolean) [default false] Parses line breaks as `<br>`, without
   needing 2 spaces at the end of the line **(since v1.5.1)**
 
   ```md
   a line  
   wrapped in two
   ```
    
   turns into:
    
   ```html
   <p>a line<br>
   wrapped in two</p>
   ```

 * **requireSpaceBeforeHeadingText**: (boolean) [default false] Makes adding a space between `#` and the header text mandatory **(since v1.5.3)**
 
 * **ghMentions**: (boolean) [default false] Enables github @mentions, which link to the username mentioned **(since v1.6.0)**
 
 * **ghMentionsLink**: (string) [default `https://github.com/{u}`] Changes the link generated by @mentions.
   Showdown will replace `{u}` with the username. Only applies if ghMentions option is enabled.
   Example: `@tivie` with ghMentionsOption set to `//mysite.com/{u}/profile` will result in `<a href="//mysite.com/tivie/profile">@tivie</a>`
 
 * **encodeEmails**: (boolean) [default true] Enable e-mail addresses encoding through the use of Character Entities, transforming ASCII e-mail addresses into its equivalent decimal entities. (since v1.6.1)

   NOTE: Prior to version 1.6.1, emails would always be obfuscated through dec and hex encoding.

 * **openLinksInNewWindow**: (boolean) [default false] Open all links in new windows
   (by adding the attribute `target="_blank"` to `<a>` tags) **(since v1.7.0)**

 * **backslashEscapesHTMLTags**: (boolean) [default false] Support for HTML Tag escaping. ex: `\<div>foo\</div>` **(since v1.7.2)**

 * **emoji**: (boolean) [default false] Enable emoji support. Ex: `this is a :smile: emoji`
   For more info on available emojis, see https://github.com/showdownjs/showdown/wiki/Emojis **(since v.1.8.0)**

 * **underline**: (boolean) [default false] ***EXPERIMENTAL FEATURE*** Enable support for underline.
   Syntax is **double** or **triple** **underscores** ex: `__underlined word__`. With this option enabled, underscores are no longer parses into `<em>` and `<strong>`.

 * **completeHTMLDocument**: (boolean) [default false] Outputs a complete html document,
   including `<html>`, `<head>` and `<body>` tags' instead of an HTML fragment. (since v.1.8.5)

 * **metadata**: (boolean) [default false] Enable support for document metadata (defined at the top of the document
   between `«««` and `»»»` or between `---` and `---`).  (since v.1.8.5)
   
   ```js
   var conv = new showdown.Converter({metadata: true});
   var html = conv.makeHtml(someMd);
   var metadata = conv.getMetadata(); // returns an object with the document metadata
   ```

 * **splitAdjacentBlockquotes**: (boolean) [default false] Split adjacent blockquote blocks.(since v.1.8.6)

 **NOTE**: Please note that until **version 1.6.0**, all of these options are ***DISABLED*** by default in the cli tool.


 ## Flavors

 You can also use flavors or presets to set the correct options automatically, so that showdown behaves like popular markdown flavors.

 Currently, the following flavors are available:

 * original - original markdown flavor as in [John Gruber's spec](https://daringfireball.net/projects/markdown/)
 * vanilla  - showdown base flavor (as from v1.3.1)
 * github   - GFM (GitHub Flavored Markdown)


 ### Global
 ```javascript
 showdown.setFlavor('github');
 ```

 ### Instance
 ```javascript
 converter.setFlavor('github');
 ```


 ## CLI Tool

 Showdown also comes bundled with a Command Line Interface tool. You can check the [CLI wiki page][cli-wiki] for more info

 ## Integration with AngularJS

 ShowdownJS project also provides seamlessly integration with AngularJS via a "plugin".
 Please visit https://github.com/showdownjs/ngShowdown for more information.

 ## Integration with TypeScript

 If you're using TypeScript you maybe want to use the types from [DefinitelyTyped][definitely-typed]

 ## Integration with SystemJS/JSPM

 Integration with SystemJS can be obtained via the third party ["system-md" plugin](https://github.com/guybedford/system-md).

 ## Integration with VueJS

 To use ShowdownJS as a Vue component quickly, you can check [vue-showdown](https://vue-showdown.js.org/).

 ## XSS vulnerability

 Showdown doesn't sanitize the input. This is by design since markdown relies on it to allow certain features to be correctly parsed into HTML.
 This, however, means XSS injection is quite possible.

 Please refer to the wiki article [Markdown's XSS Vulnerability (and how to mitigate it)][xss-wiki]
 for more information.

 ## Extensions

 Showdown allows additional functionality to be loaded via extensions. (you can find a list of known showdown extensions [here][ext-wiki])
 You can also find a boilerplate, to create your own extensions in [this repository][boilerplate-repo]

 ### Client-side Extension Usage

 ```js
 <script src="showdown.js" />
 <script src="twitter-extension.js" />

 var converter = new showdown.Converter({ extensions: ['twitter'] });
 ```

 ### Server-side Extension Usage

 ```js
 var showdown    = require('showdown'),
    myExtension = require('myExtension'),
    converter = new showdown.Converter({ extensions: ['myExtension'] });
 ```

 ## Tests

 A suite of tests is available which require node.js.  Once node is installed, run the following command from
 the project root to install the dependencies:

    npm install

 Once installed the tests can be run from the project root using:

    npm test

 New test cases can easily be added.  Create a markdown file (ending in `.md`) which contains the markdown to test.
 Create a `.html` file of the exact same name.  It will automatically be tested when the tests are executed with `mocha`.

 You can request a new feature by submitting an issue. If you would like to implement a new feature feel free to issue a
 Pull Request.


 ### Pull requests (PRs)
 PRs are awesome. However, before you submit your pull request consider the following guidelines:

 - Search GitHub for an open or closed Pull Request that relates to your submission. You don't want to duplicate effort.
 - When issuing PRs that change code, make your changes in a new git branch based on master:

   ```bash
   git checkout -b my-fix-branch master
   ```

 - Documentation (i.e: README.md) changes can be made directly against master.
 - Run the full test suite before submitting and make sure all tests pass (obviously =P).
 - Try to follow our [**coding style rules**][coding-rules].
   Breaking them prevents the PR to pass the tests.
 - Refrain from fixing multiple issues in the same pull request. It's preferable to open multiple small PRs instead of one
   hard to review big one.
 - If the PR introduces a new feature or fixes an issue, please add the appropriate test case.
 - We use commit notes to generate the changelog. It's extremely helpful if your commit messages adhere to the
 [**AngularJS Git Commit Guidelines**][ng-commit-guide].
 - If we suggest changes then:
     - Make the required updates.
     - Re-run the Angular test suite to ensure tests are still passing.
     - Rebase your branch and force push to your GitHub repository (this will update your Pull Request):

     ```bash
     git rebase master -i
     git push origin my-fix-branch -f
     ```
 - After your pull request is merged, you can safely delete your branch.

 If you have time to contribute to this project, we feel obliged that you get credit for it.
 These rules enable us to review your PR faster and will give you appropriate credit in your GitHub profile.
 We thank you in advance for your contribution!

 # ROADMAP TO VERSION 2.0


 ## Options

 - [ ] **ghCompatibleHeaderId** (removal)

    Will be removed and **will become the default behavior**.
    
 - [ ] **customizedHeaderId** (removal)

    This option introduced non compliant syntax so it really belongs in an extension.
    The new **listener extension system** allows users to directly modify and customize
    the HTML and add any attributes they wish. 

 - [ ] **rawPrefixHeaderId** (removal)

    This option will be superseeded by the option `rawHeaderId`. So basically activating `rawHeaderId` will make
    showdown only to replace spaces, ', ", > and < with dashes (-) from generated header ids, including prefixes.

 - [X] **literalMidWordAsterisks** (removal)

    This option is weird, hard to maintain and really... makes little sense.

 - [X] **excludeTrailingPunctuationFromURLs** (removal)

    This option will be removed and will be the default behavior from now on.

 - [ ] **strikethrough** (change)

    Will be enabled by default

 - [ ] **disableForced4SpacesIndentedSublists** (to think/postpone)

    This was only a temporary option for backwards compatibility reason. However, most flavours support lists indented
    with 2 spaces, so it puts us in a tight spot, specially since some markdown beautifiers out there insist in
    indenting lists with 2 spaces, probably in a misguided try to follow the CommonMark spec.
    
    The CommonMark spec is, IMHO, a bit confusing for users regarding this, since list sub-blocks (and lists) 
    are determined by the spaces from the start of the line and the first character after the list mark. And the proof
    are the MD beautifiers out there, which misinterpreted the spec and made a mess 
    
    Showdown syntax is actually easier (and fully compliant with the original spec): if you indent something 4 spaces,
    it becomes a sub-block. Since lists are blocks, you must indent it 4 spaces for it to become a sub-block.
    
    Regardless, we kinda have 2 solutions:
    
    - Drop support for 2 space indentation (and make a lot of users confused since GFM, CommonMark and others allow this)
    - Create a new list subparser that can be turned on with an option, like gfmListStyle
      (but postpones even more the alpha 2.0 release since the list subparser is probably the hardest thing to rewrite)
    
    Tough choices...

 - [ ] **simpleLineBreaks** (change)

    Will be removed from Github Flavor since github only does this in comments (which is weird...)

 - [ ] **openLinksInNewWindow** (removal)

    Will be removed in favor of the new listener extension, which will allow users to manipulate HTML tags attributes
    directly.
    
 - [ ] Revamp the option system

    Revamp the option system so that it becomes more simple. Right now, it's really confusing. And option names are weird
    too. The idea is to pass options to the constructor under an option object, that can have hierarchical structure.
    Ex:
    
    ```js
    var conv = new showdown.Converter({ 
      options: { 
        links: {
          autoLinks: true
        },
        headings: {
          startLevel: 2
        }
      }
    });
    ``` 

 ## Legacy Code Removal
 - [ ] Legacy extension support
        
    Old extensions that inject directly into extensions object property will no longer be supported
    
 - [ ] HTML and OUTPUT extensions
    
    HTML and OTP extensions will be dropped in favor of Listener Extensions. We might even give them a new name
    
 ## Subparsers
 - [X] **Anchors**: Revamp the anchors subparser so it calls strikethrough, bold, italic and underline directly
 - [X] **autoLinks**: Fix some lingering bugs and issues with autolinks

 ## Priority Bugs
 - [X] **#355**: *simplifiedAutoLink URLs inside parenthesis followed by another character are not parsed correctly*
 - [X] **#534**: *Multiple parentheses () in url link is not parsed correctly*
 - [ ] **#367**: *sublists rendering with 2 spaces* - related to disableForced4SpacesIndentedSublists option...
 - [ ] **#537**: *master branch doesn't work in a web worker*

 ## CLI
 - [ ] Refactor the CLI
 - [ ] **#381**: *Support for src and dst directories in showdown cli*
 - [ ] **#584**: *Fails to read from stdin*
 - [ ] **#554**: *CLI not working with jsdom v10*

 ## Other stuff
 - [X] Regexp rewrite for more performance oompf
 - [ ] Full unit testing
 - [ ] Better error reporting

 ## Stuff that probably won't make it to v2.0
 - [ ] **#486**: *A backslash at the end of the line is a hard line break*
 - [ ] **#548**: *anchors and images of subParser are errors when they are specific strings*
 - [ ] **#549**: *Strange parsing issue with `<pre><code>`*
 - [ ] Rethink the global variable

 ## NEW Features

 ### Event system
 - [X] Listener system revamp
 - [ ] Standardize events for all event types
 - [ ] Unit testing
 - [ ] Functional testing

 This should address:
 - **#567**: Allow not making header ids lowercase
 - **#540**: Add complete class to the tasklist list element

 ### MD to HTML conversion
 - [X] Basic support
 - [X] Basic functional testcase
 - [ ] Advanced support for all showdown MD features
 - [ ] Advanced functional testcase
 - [ ] Unit testing

 ## Documentation (for v2.0)
 - [ ] Options
 - [ ] Extensions (and the new event system)
 - [ ] Cookbook (with stuff for backwards compatibility, specially regarding removed options)

 # Event System

 ## Introduction


 ## The Event Object


 ## Events

 Events are raised when a subparser is run (or about to be run).
 Within a subparser, the events always follow a certain order (sequence). For instance, **.before** events always run before **.captureStart**.
 Each subparser raises several events sequentially:

 1. **.start**: **always runs** except it subparser is disabled

    Raised when the **subparser has started**, but no capturing or any modification to the text was done.
    
    **Always runs** (except if the subparser is deactivated through options).
    
    ***Properties***:
         
    | property | type      | access     | description                                                        |
    |----------|-----------|------------|--------------------------------------------------------------------|
    | input    | string    | read       | The full text that was passed to the subparser                     |
    | output   | string    | write      | The full text with modification that will be passed along the chain|
    | regex    | null      |            |                                                                    |
    | matches  | null      |            |                                                                    |
    
    Usually you would want to use this event if you wish to change the input to the subparser
     
 2. **.captureStart**: *might not be run*;
 
     Raised when a regex match is found and a capture was successful. Some normalization and modification 
     of the regex captured groups might be performed.
     
     Might not be run if no regex match is found.
     
     ***Properties***:
     
     | property | type      | access     | description                                                        |
     |----------|-----------|------------|--------------------------------------------------------------------|
     | input    | string    | read       | The captured text                                                  |
     | output   | string    | write      | The text that will be passed to the subparser/other listeners      |
     | regex    | RegExp    | readonly   | Regular Expression used to capture groups                          |
     | matches  | object    | read/write | Matches groups. Changes to this object are reflected in the output |
     
     Usually you would want to use this event if you wish to modify a certain subparser behavior.
     Exs: remove all title attributes from links; change indentation of code blocks; etc...
 
 3. **.captureEnd**: *might not be run*;
 
    Raised after the modifications to the captured text are done but before the replacement is introduced in the document.
    
    Might not be run if no regex match is found.
         
    ***Properties***:
    
    | property   | type      | access     | description                                                                    |
    |------------|-----------|------------|--------------------------------------------------------------------------------|
    | input      | string    | read       | The captured text                                                              |
    | output     | string    | write      | The text that will be passed to the subparser/other listeners                  |
    | regex      | RegExp    | readonly   | Regular Expression used to capture groups                                      |
    | matches    | object    | read/write | Keypairs of matches groups. Changes to this object are reflected in the output |
    | attributes | object    | read/write | Attributes to add to the HTML output                                           |
 
 4. **.beforeHash**: *might not be run*;
 
    Raised before the output is hashed.
    
    Always run (except if the subparser was deactivated through options), even if no hashing is performed. 
    
    ***Properties***:
        
    | property | type       | access     | description                                                        |
    |----------|------------|------------|--------------------------------------------------------------------|
    | input    | string     | read       | The captured text                                                  |
    | output   | string     | write      | The text that will be passed to the subparser/other listeners      |
    | regex    | null       |            |                                                                    |
    | matches  | null       |            |                                                                    |
 
    Usually you would want to use this event if you wish change the subparser output before it is hashed
 
 5. **.end**: *always runs*;
 
    Raised when the subparser has finished its work and is about to exit.
     
    Always runs (except if the subparser is deactivated through options).
    
    ***Properties***:
    
    | property | type      | access     | description                                                        |
    |----------|-----------|------------|--------------------------------------------------------------------|
    | input    | string    | read       | The partial/full text with the subparser modifications             |
    | output   | string    | write      | The text that will be passed to other subparsers                   |
    | regex    | null      |            |                                                                    |
    | matches  | null      |            |                                                                    |
     
    Usually you would want to use this event if you wish change the subparser hashed output


 ### Special Events

 There are some special events that are useful for *"positioning"* a listener extension in the main chain of events.
 Usually these extensions introduce new syntax that, due to precedence 
 These events are always guaranteed to be called, regardless of options or circumstances. 

 1. **.before_{subparserName}**: *always runs*
    
    Raised just before the **{subparserName} is about to be entered**.
    
    ***Properties***:
         
    | property | type      | access     | description                                                        |
    |----------|-----------|------------|--------------------------------------------------------------------|
    | input    | string    | read       | The full text that was passed to the subparser                     |
    | output   | string    | write      | The full text with modification that will be passed along the chain|
    | regex    | null      |            |                                                                    |
    | matches  | null      |            |                                                                    |
    
 2. **.after**.{subparserName}: *always runs*;
 
    Raised when the **{subparserName} has exited** and before the next one is called.
    
    ***Properties***:
    
    | property | type      | access     | description                                                        |
    |----------|-----------|------------|--------------------------------------------------------------------|
    | input    | string    | read       | The partial/full text with the subparser modifications             |
    | output   | string    | write      | The text that will be passed to other subparsers                   |
    | regex    | null      |            |                                                                    |
    | matches  | null      |            |                                                                    |

 
 ### Notes

 - There are 2 main differences between **before.{subparserName}** and **{subparserName}.start**.
   
     1. **before.{subparserName}** is always guaranteed to be called, even if the subparser is disabled, 
        while **{subparserName}.start** doesn't.
        
        ex: `makehtml.before.strikethrough` is always called even if the option `strikethrough` is false 
        
     2. **before.{subparserName}** is only raised once in a span context while **{subparserName}.start** is raised
        everytime **{subparserName}** is called.

    As a rule of thumb,
