+
+Basic Usage
+==============
+
+The `CommonMarkConverter` class provides a simple wrapper for converting Markdown to HTML:
+
+~~~php
+<?php
+
+use League\CommonMark\CommonMarkConverter;
+
+$converter = new CommonMarkConverter();
+echo $converter->convertToHtml('# Hello World!');
+
+// <h1>Hello World!</h1>
+~~~
+
+Or if you want Github-Flavored Markdown:
+
+```php
+<?php
+
+use League\CommonMark\GithubFlavoredMarkdownConverter;
+
+$converter = new GithubFlavoredMarkdownConverter();
+echo $converter->convertToHtml('# Hello World!');
+
+// <h1>Hello World!</h1>
+```
+
+<i class="fa fa-exclamation-triangle"></i>
+**Important:** See the [security](/2.0/security/) section for important details on avoiding security misconfigurations.
+
+[Additional customization](/2.0/customization/overview/) is also possible, and we have many handy [extensions](/2.0/extensions/) to enable additional syntax and features.
+
+## Supported Character Encodings
+
+Please note that only UTF-8 and ASCII encodings are supported.  If your Markdown uses a different encoding please convert it to UTF-8 before running it through this library.
+
+## Return Value
+
+The `convertToHtml()` method actually returns an instance of `League\CommonMark\Output\RenderedContentInterface`.  You can cast this (implicitly, as shown above, or explicitly) to a `string` or call `getContent()` to get the final HTML output.

+
+Configuration
+=============
+
+You can provide an array of configuration options to the `CommonMarkConverter` when creating it:
+
+~~~php
+<?php
+
+use League\CommonMark\CommonMarkConverter;
+
+$converter = new CommonMarkConverter([
+    'renderer' => [
+        'block_separator' => "\n",
+        'inner_separator' => "\n",
+        'soft_break'      => "\n",
+    ],
+    'enable_em' => true,
+    'enable_strong' => true,
+    'use_asterisk' => true,
+    'use_underscore' => true,
+    'unordered_list_markers' => ['-', '*', '+'],
+    'html_input' => 'escape',
+    'allow_unsafe_links' => false,
+    'max_nesting_level' => INF,
+]);
+~~~
+
+Here's a list of currently-supported options:
+
+* `renderer` - Array of options for rendering HTML
+  * `block_separator` - String to use for separating renderer block elements
+  * `inner_separator` - String to use for separating inner block contents
+  * `soft_break` - String to use for rendering soft breaks
+* `enable_em` - Disable `<em>` parsing by setting to `false`; enable with `true` (default: `true`)
+* `enable_strong` - Disable `<strong>` parsing by setting to `false`; enable with `true` (default: `true`)
+* `use_asterisk` - Disable parsing of `*` for emphasis by setting to `false`; enable with `true` (default: `true`)
+* `use_underscore` - Disable parsing of `_` for emphasis by setting to `false`; enable with `true` (default: `true`)
+* `unordered_list_markers` - Array of characters that can be used to indicated a bulleted list (default: `["-", "*", "+"]`)
+* `html_input` - How to handle HTML input.  Set this option to one of the following strings:
+  - `strip` - Strip all HTML (equivalent to `'safe' => true`)
+  - `allow` - Allow all HTML input as-is (default value; equivalent to `'safe' => false)
+  - `escape` - Escape all HTML
+* `allow_unsafe_links` - Remove risky link and image URLs by setting this to `false` (default: `true`)
+* `max_nesting_level` - The maximum nesting level for blocks (default: infinite). Setting this to a positive integer can help protect against long parse times and/or segfaults if blocks are too deeply-nested. Added in 0.17.
+
+Additional configuration options are available for some of the [available extensions](/2.0/customization/extensions/) - refer to their individual documentation for more details.
+
+## Environment
+
+The configuration is ultimately passed to (and managed via) the `Environment`.  If you're creating your own `Environment`, simply pass your config array into its constructor instead.
+
+The `Environment` also exposes three methods for managing the configuration:
+
+* `setConfig(array $config = [])` - Replace the current configuration with something else
+* `mergeConfig(array $config = [])` - Recursively merge the current configuration with the given options
+* `getConfig(string $key, $default = null)` - Returns the config value. For nested configs, use a `/`-separate path; for example: `renderer/soft_break`
+

+description: Instructions on how to install the league/commonmark library
+---
+
+# Installation
+
+The recommended installation method is via Composer.
+
+In your project root just run:
+
+~~~bash
+composer require league/commonmark:^2.0
+~~~
+
+Ensure that you’ve set up your project to [autoload Composer-installed packages](https://getcomposer.org/doc/00-intro.md#autoloading).
+
+## Versioning
+
+[SemVer](http://semver.org/) will be followed closely.  **It's highly recommended that you use [Composer's caret operator](https://getcomposer.org/doc/articles/versions.md#caret) to ensure compatibility**; for example: `^2.0`.  This is equivalent to `>=2.0 <3.0`.

+title: Security
+description: How to configure league/commonmark against possible security issues when handling untrusted user input
+---
+
+Security
+========
+
+In order to be fully compliant with the CommonMark spec, certain security settings are disabled by default.  You will want to configure these settings if untrusted users will be providing the Markdown content:
+
+ - `html_input`: How to handle raw HTML
+ - `allow_unsafe_links`: Whether unsafe links are permitted
+ - `max_nesting_level`: Protected against long render times or segfaults
+
+Further information about each option can be found below.
+
+## HTML Input
+
+**All HTML input is unescaped by default.**  This behavior ensures that league/commonmark is 100% compliant with the CommonMark spec.
+
+If you're developing an application which renders user-provided Markdown from potentially untrusted users, you are **strongly** encouraged to set the `html_input` option in your configuration to either `escape` or `strip`:
+
+### Example - Escape all raw HTML input:
+
+~~~php
+use League\CommonMark\CommonMarkConverter;
+
+$converter = new CommonMarkConverter(['html_input' => 'escape']);
+echo $converter->convertToHtml('<script>alert("Hello XSS!");</script>');
+
+// &lt;script&gt;alert("Hello XSS!");&lt;/script&gt;
+~~~
+
+### Example - Strip all HTML from the input:
+~~~php
+use League\CommonMark\CommonMarkConverter;
+
+$converter = new CommonMarkConverter(['html_input' => 'strip']);
+echo $converter->convertToHtml('<script>alert("Hello XSS!");</script>');
+
+// (empty output)
+~~~
+
+**Failing to set this option could make your site vulnerable to cross-site scripting (XSS) attacks!**
+
+See the [configuration](/2.0/configuration/) section for more information.
+
+## Unsafe Links
+
+Unsafe links are also allowed by default due to CommonMark spec compliance.  An unsafe link is one that uses any of these protocols:
+
+ - `javascript:`
+ - `vbscript:`
+ - `file:`
+ - `data:` (except for `data:image` in png, gif, jpeg, or webp format)
+
+To prevent these from being parsed and rendered, you should set the `allow_unsafe_links` option to `false`.
+
+## Nesting Level
+
+**No maximum nesting level is enforced by default.**  Markdown content which is too deeply-nested (like 10,000 nested blockquotes: '> > > > > ...') [could result in long render times or segfaults](https://github.com/thephpleague/commonmark/issues/243#issuecomment-217580285).
+
+If you need to parse untrusted input, consider setting a reasonable `max_nesting_level` (perhaps 10-50) depending on your needs.  Once this nesting level is hit, any subsequent Markdown will be rendered as plain text.
+
+### Example - Prevent deep nesting
+
+~~~php
+use League\CommonMark\CommonMarkConverter;
+
+$markdown = str_repeat('> ', 10000) . ' Foo';
+
+$converter = new CommonMarkConverter(['max_nesting_level' => 5]);
+echo $converter->convertToHtml($markdown);
+
+// <blockquote>
+//   <blockquote>
+//     <blockquote>
+//       <blockquote>
+//         <blockquote>
+//           <p>&gt; &gt; &gt; &gt; &gt; &gt; &gt; ... Foo</p></blockquote>
+//       </blockquote>
+//     </blockquote>
+//   </blockquote>
+// </blockquote>
+~~~
+
+See the [configuration](/2.0/configuration/) section for more information.
+
+## Additional Filtering
+
+Although this library does offer these security features out-of-the-box, some users may opt to also run the HTML output through additional filtering layers (like HTMLPurifier).  If you do this, make sure you **thoroughly** test your additional post-processing steps and configure them to work properly with the types of HTML elements and attributes that converted Markdown might produce, otherwise, you may end up with weird behavior like missing images, broken links, mismatched HTML tags, etc.

+title: Upgrading from 1.5 to 2.0
+description: Guide to upgrading to newer versions of this library
+---
+
+# Upgrading from 1.5 to 2.0
+
+## Minimum PHP Version
+
+The minimum supported PHP version was increased from 7.1 to 7.2.
+
+## `CommonMarkConverter` Return Type
+
+In 1.x, calling `convertToHtml()` would return a `string`. In 2.x this changed to return a `RenderedContentInterface`.  To get the resulting HTML, either cast it to a `string` or call `->getContent()`.  (This new interface extends from `Stringable` so you can type hint against that instead, if needed.)
+
+## Method Return Types
+
+Return types have been added to virtually all class and interface methods.  If you implement or extend anything from this library, ensure you also have the proper return types added.
+
+## Classes/Namespaces Renamed
+
+Many classes now live in different namespaces, and some have also been renamed.  Here's a quick guide showing their new locations:
+
+_(Note that the base namespace of `League\CommonMark` has been omitted from this table for brevity.)_

+## New Block Parsing Approach
+
+We've completely changed how block parsing works in 2.0.  In a nutshell, 1.x had parsing responsibilities split between
+the parser and the node. But nodes should be "dumb" and not know anything about how they are parsed - they should only
+know the bare minimum needed for rendering.
+
+As a result, 2.x has delegated the parsing responsibilities to two different interfaces:
+
+|  Responsibility                                           | Old Method (1.x)                           | New Method (2.0)                                               |

+| Identifying the start of a block                          | `BlockParserInterface::parse()`            | `BlockStartParserInterface::tryStart()`                        |

+| Determining if the block can have lazy continuation lines | `AbstractBlock::isCode()`                  | `BlockContinueParserInterface::canHaveLazyContinuationLines()` |
+| Determining if the block can contain certain child blocks | `AbstractBlock::canContain()`              | `BlockContinueParserInterface::canContain()`                   |
+| Determining if the block continues on the next line       | `AbstractBlock::matchesNextLine()`         | `BlockContinueParserInterface::tryContinue()`                  |
+| Adding the next line to the block                         | `AbstractBlock::handleRemainingContents()` | `BlockContinueParserInterface::addLine()`                      |
+| Finalizing the block and its contents                     | `AbstractBlock::finalize()`                | `BlockContinueParserInterface::closeBlock()`                   |
+
+As a result of making this change, the `addBlockParser()` method on `ConfigurableEnvironmentInterface` has changed to `addBlockStartParser()`.
+
+See [the block parsing documentation](/2.0/customization/block-parsing/) for more information on this new approach.
+
+## Rendering Changes
+
+This library no longer differentiates between block renderers and inline renderers - everything now uses "node renderers" which allow us to have a unified approach to rendering!  As a result, the following changes were made, which you may need to change in your custom extensions:
+
+| Old Method/Interface (1.x)                              | New Method/Interface (2.0)                        |
+| ------------------------------------------------------- | ------------------------------------------------- |
+| `BlockRendererInterface`                                | `NodeRendererInterface`                           |
+| `InlineRendererInterface`                               | `NodeRendererInterface`                           |
+| `EnvironmentInterface::getBlockRenderersForClass()`     | `EnvironmentInterface::getRenderersForClass()`    |
+| `EnvironmentInterface::getInlineRenderersForClass()`    | `EnvironmentInterface::getRenderersForClass()`    |
+| `ConfigurableEnvironmentInterface::addBlockRenderer()`  | `ConfigurableEnvironmentInterface::addRenderer()` |
+| `ConfigurableEnvironmentInterface::addInlineRenderer()` | `ConfigurableEnvironmentInterface::addRenderer()` |
+| `ElementRendererInterface::renderBlock()`               | `ChildNodeRendererInterface::renderNodes()`       |
+| `ElementRendererInterface::renderBlocks()`              | `ChildNodeRendererInterface::renderNodes()`       |
+| `ElementRendererInterface::renderInline()`              | `ChildNodeRendererInterface::renderNodes()`       |
+| `ElementRendererInterface::renderInlines()`             | `ChildNodeRendererInterface::renderNodes()`       |
+| `HtmlRenderer::renderBlock($document)`                  | `HtmlRenderer::renderDocument()`                  |
+
+Renderers now implement the unified `NodeRendererInterface` which has a similar (but slightly different) signature from
+the old `BlockRendererInterface` and `InlineRendererInterface` interfaces:
+
+~~~php
+/**
+ * @param Node                       $node
+ * @param ChildNodeRendererInterface $childRenderer
+ *
+ * @return HtmlElement|string|null
+ */
+public function render(Node $node, ChildNodeRendererInterface $childRenderer);
+~~~
+
+The element being rendered is still passed in the first argument, and the object that helps you render children is still
+passed in the second argument.  Note that blocks are no longer told whether they're being rendered in a tight list - if you
+need to know about this, traverse up the `$node` AST yourself and check any `ListBlock` ancestor for tightness.
+
+## Removed Classes
+
+The following classes have been removed:
+
+| Class name in 1.x              | Replacement / Notes                                                                                           |
+| ------------------------------ | ------------------------------------------------------------------------------------------------------------- |
+| `AbstractStringContainerBlock` | Use `extends AbstractBlock implements StringContainerInterface` instead. Note the new method names.           |
+| `Context`                      | Use `MarkdownParserState` instead (has different methods but serves a similar purpose)                        |
+| `ContextInterface`             | Use `MarkdownParserStateInterface` instead (has different methods but serves a similar purpose)               |
+| `Converter`                    | Use `CommonMarkConverter` instead. Note that this has a different constructor but the same methods.           |
+| `ConverterInterface`           | Use `MarkdownConverterInterface`.  This interface has the same methods so it should be a drop-in replacement. |
+| `UnmatchedBlockCloser`         | No longer needed 2.x                                                                                          |
+
+## `EnvironmentInterface::HTML_INPUT_*` constants moved
+
+The following constants have been moved:
+
+| Old Location (1.x)                        | New Location (2.0)   |
+| ----------------------------------------- | -------------------- |
+| `EnvironmentInterface::HTML_INPUT_ALLOW`  | `HtmlFilter::ALLOW`  |
+| `EnvironmentInterface::HTML_INPUT_ESCAPE` | `HtmlFilter::ESCAPE` |
+| `EnvironmentInterface::HTML_INPUT_STRIP`  | `HtmlFilter::STRIP`  |
+
+## Renamed Methods
+
+The following methods have been renamed:
+
+| Class                                              | Old Name (1.x)     | New Name (2.0)          |
+| -------------------------------------------------- | ------------------ | ----------------------- |
+| `Environment` / `ConfigurableEnvironmentInterface` | `addBlockParser()` | `addBlockStartParser()` |
+| `ReferenceMap` / `ReferenceMapInterface`           | `addReference()`   | `add()`                 |
+| `ReferenceMap` / `ReferenceMapInterface`           | `getReference()`   | `get()`                 |
+| `ReferenceMap` / `ReferenceMapInterface`           | `listReferences()` | `getIterator()`         |
+
+## Visibility Changes
+
+The following properties have had their visibility changed:
+
+| Property               | Was (1.x) | Is Now (2.0) | Notes                                     |
+| ---------------------- | --------- | ------------ | ----------------------------------------- |
+| `TableCell::$align`    | `public`  | `private`    | Use `getAlign()` and `setAlign()` instead |
+| `TableCell::$type`     | `public`  | `private`    | Use `getType()` and `setType()` instead   |
+| `TableSection::$type`  | `public`  | `private`    | Use `getType()` instead                   |
+
+## New approach to the `ReferenceParser`
+
+The `ReferenceParser` class in 1.x worked on complete paragraphs of text.  This has been changed in 2.x to work in a more-gradual fashion, where parsing is done on-the-fly as new lines are added.
+Whereas you may have previously called `parse()` on a `Cursor` once on something containing multiple lines, you should now call `parse()` on each line of text and then later call `getReferences()`
+to check what has been parsed.
+
+## `Html5Entities` utility class removed
+
+Use the `Html5EntityDecoder` utility class instead.
+
+## `bin/commonmark` command
+
+This command was buggy to test and was relatively unpopular, so it has been removed. If you need this type of functionality, consider writing your own script with a Converter/Environment configured exactly how you want it.
+
+## `CommonMarkConverter::VERSION` constant
+
+This previously-deprecated constant was removed in 2.0 Use `\Composer\InstalledVersions` provided by composer-runtime-api instead.
+
+## `HeadingPermalinkRenderer::DEFAULT_INNER_CONTENTS` constant
+
+This previously-deprecated constant was removed in 2.0. Use `HeadingPermalinkRenderer::DEFAULT_SYMBOL` instead.
+
+## `heading_permalink/inner_contents` configuration option
+
+This previously-deprecated configuration option was removed in 2.0. Use `heading_permalink/symbol` instead.
+
+## `ArrayCollection` methods
+
+Several methods were removed from this class - here are the methods along with possible alternatives you can switch to:
+
+| Removed Method Name | Alternative                                          |
+| ------------------- | ---------------------------------------------------- |
+| `add($value)`       | `$collection[] = $value`                             |
+| `set($key, $value)` | `$collection[$key] = $value`                         |
+| `get($key)`         | `$collection[$key]`                                  |
+| `remove($key)`      | `unset($collection[$key])`                           |
+| `isEmpty()`         | `count($collection) === 0`                           |
+| `contains($value)`  | `in_array($value, $collection->toArray(), true)`     |
+| `indexOf($value)`   | `array_search($value, $collection->toArray(), true)` |
+| `containsKey($key)` | `isset($collection[$key])`                           |
+| `replaceWith()`     | (none provided)                                      |
+| `removeGaps()`      | (none provided)                                      |
+
+## Unused methods
+
+The following unused methods have been removed:
+
+ - `Delimiter::setCanClose()`

+$converter = new CommonMarkConverter();
+echo $converter->convertToHtml('# Hello World!');
+
+// <h1>Hello World!</h1>
+```
+
+## Security
+
+All CommonMark features are supported by default, including raw HTML and unsafe links, which you may want to disable using the `html_input` and `allow_unsafe_links` options:
+
+```php
+use League\CommonMark\CommonMarkConverter;
+
+$converter = new CommonMarkConverter(['html_input' => 'escape', 'allow_unsafe_links' => false]);
+echo $converter->convertToHtml('# Hello World!');
+
+// <h1>Hello World!</h1>
+```
+
