Changed

  • Changed the converter return type
    • CommonMarkConverter::convertToHtml() now returns an instance of RenderedContentInterface. This can be cast to a string for backward compatibility with 1.x.
  • Table of Contents items are no longer wrapped with <p> tags (#613)
  • Heading Permalinks now link to element IDs instead of using name attributes (#602)
  • Heading Permalink IDs and URL fragments now have a content prefix by default (#602)
  • Changes to configuration options:
    • enable_em has been renamed to commonmark/enable_em
    • enable_strong has been renamed to commonmark/enable_strong
    • use_asterisk has been renamed to commonmark/use_asterisk
    • use_underscore has been renamed to commonmark/use_underscore
    • unordered_list_markers has been renamed to commonmark/unordered_list_markers
    • mentions/*/symbol has been renamed to mentions/*/prefix
    • mentions/*/regex has been renamed to mentions/*/pattern and requires partial regular expressions (without delimiters or flags)
    • max_nesting_level now defaults to PHP_INT_MAX and no longer supports floats
    • heading_permalink/slug_normalizer has been renamed to slug_normalizer/instance
  • Event dispatching is now fully PSR-14 compliant
  • Moved and renamed several classes - see the full list here
  • The HeadingPermalinkExtension and FootnoteExtension were modified to ensure they never produce a slug which conflicts with slugs created by the other extension
  • SlugNormalizer::normalizer() now supports optional prefixes and max length options passed in via the $context argument
  • The AbstractBlock::$data and AbstractInline::$data arrays were replaced with a Data array-like object on the base Node class
  • Implemented a new approach to block parsing. This was a massive change, so here are the highlights:
    • Functionality previously found in block parsers and node elements has moved to block parser factories and block parsers, respectively (more details)
    • ConfigurableEnvironmentInterface::addBlockParser() is now EnvironmentBuilderInterface::addBlockParserFactory()
    • ReferenceParser was re-implemented and works completely different than before
    • The paragraph parser no longer needs to be added manually to the environment
  • Implemented a new approach to inline parsing where parsers can now specify longer strings or regular expressions they want to parse (instead of just single characters):
    • InlineParserInterface::getCharacters() is now getMatchDefinition() and returns an instance of InlineParserMatch
    • InlineParserContext::__construct() now requires the contents to be provided as a Cursor instead of a string
  • Implemented delimiter parsing as a special type of inline parser (via the new DelimiterParser class)
  • Changed block and inline rendering to use common methods and interfaces
    • BlockRendererInterface and InlineRendererInterface were replaced by NodeRendererInterface with slightly different parameters. All core renderers now implement this interface.
    • ConfigurableEnvironmentInterface::addBlockRenderer() and addInlineRenderer() were combined into EnvironmentBuilderInterface::addRenderer()
    • EnvironmentInterface::getBlockRenderersForClass() and getInlineRenderersForClass() are now just getRenderersForClass()
  • Completely refactored the Configuration implementation
    • All configuration-specific classes have been moved into a new league/config package with a new namespace
    • Configuration objects must now be configured with a schema and all options must match that schema - arbitrary keys are no longer permitted
    • Configuration::__construct() no longer accepts the default configuration values - use Configuration::merge() instead
    • ConfigurationInterface now only contains a get(string $key); this method no longer allows arbitrary default values to be returned if the option is missing
    • ConfigurableEnvironmentInterface was renamed to EnvironmentBuilderInterface
    • ExtensionInterface::register() now requires an EnvironmentBuilderInterface param instead of ConfigurableEnvironmentInterface
  • Added missing return types to virtually every class and interface method
  • Re-implemented the GFM Autolink extension using the new inline parser approach instead of document processors
    • EmailAutolinkProcessor is now EmailAutolinkParser
    • UrlAutolinkProcessor is now UrlAutolinkParser
  • HtmlElement can now properly handle array (i.e. class) and boolean (i.e. checked) attribute values
  • HtmlElement automatically flattens any attributes with array values into space-separated strings, removing duplicate entries
  • Combined separate classes/interfaces into one:
    • DisallowedRawHtmlRenderer replaces DisallowedRawHtmlBlockRenderer and DisallowedRawHtmlInlineRenderer
    • NodeRendererInterface replaces BlockRendererInterface and InlineRendererInterface
  • Renamed the following methods:
    • Environment and ConfigurableEnvironmentInterface:
      • addBlockParser() is now addBlockStartParser()
    • ReferenceMap and ReferenceMapInterface:
      • addReference() is now add()
      • getReference() is now get()
      • listReferences() is now getIterator()
    • Various node (block/inline) classes:
      • getContent() is now getLiteral()
      • setContent() is now setLiteral()
  • Moved and renamed the following constants:
    • EnvironmentInterface::HTML_INPUT_ALLOW is now HtmlFilter::ALLOW
    • EnvironmentInterface::HTML_INPUT_ESCAPE is now HtmlFilter::ESCAPE
    • EnvironmentInterface::HTML_INPUT_STRIP is now HtmlFilter::STRIP
    • TableCell::TYPE_HEAD is now TableCell::TYPE_HEADER
    • TableCell::TYPE_BODY is now TableCell::TYPE_DATA
  • Changed the visibility of the following properties:
    • AttributesInline::$attributes is now private
    • AttributesInline::$block is now private
    • TableCell::$align is now private
    • TableCell::$type is now private
    • TableSection::$type is now private
  • Several methods which previously returned $this now return void
    • Delimiter::setPrevious()
    • Node::replaceChildren()
    • Context::setTip()
    • Context::setContainer()
    • Context::setBlocksParsed()
    • AbstractStringContainer::setContent()
    • AbstractWebResource::setUrl()
  • Several classes are now marked final:
    • ArrayCollection
    • Emphasis
    • FencedCode
    • Heading
    • HtmlBlock
    • HtmlElement
    • HtmlInline
    • IndentedCode
    • Newline
    • Strikethrough
    • Strong
    • Text
  • Heading nodes no longer directly contain a copy of their inner text
  • StringContainerInterface can now be used for inlines, not just blocks
  • ArrayCollection only supports integer keys
  • HtmlElement now implements Stringable
  • Cursor::saveState() and Cursor::restoreState() now use CursorState objects instead of arrays
  • NodeWalker::next() now enters, traverses any children, and leaves all elements which may have children (basically all blocks plus any inlines with children). Previously, it only did this for elements explicitly marked as "containers".
  • InvalidOptionException was removed
  • Anything with a getReference(): ReferenceInterface method now implements ReferencableInterface
  • The SmartPunct extension now replaces all unpaired Quote elements with Text elements towards the end of parsing, making the QuoteRenderer unnecessary
  • Several changes made to the Footnote extension:
    • Footnote identifiers can no longer contain spaces
    • Anonymous footnotes can now span subsequent lines
    • Footnotes can now contain multiple lines of content, including sub-blocks, by indenting them
    • Footnote event listeners now have numbered priorities (but still execute in the same order)
    • Footnotes must now be separated from previous content by a blank line
  • The line numbers (keys) returned via MarkdownInput::getLines() now start at 1 instead of 0
  • DelimiterProcessorCollectionInterface now extends Countable
  • RegexHelper::PARTIAL_ constants must always be used in case-insensitive contexts
  • HeadingPermalinkProcessor no longer accepts text normalizers via the constructor - these must be provided via configuration instead
  • Blocks which can't contain inlines will no longer be asked to render inlines
  • AnonymousFootnoteRefParser and HeadingPermalinkProcessor now implement EnvironmentAwareInterface instead of ConfigurationAwareInterface
  • The second argument to TextNormalizerInterface::normalize() must now be an array
  • The title attribute for Link and Image nodes is now stored using a dedicated property instead of stashing it in $data
  • ListData::$delimiter now returns either ListBlock::DELIM_PERIOD or ListBlock::DELIM_PAREN instead of the literal delimiter

  • Fixed rendering of orphaned footnotes and footnote refs
  • Fixed some URL autolinks breaking too early (#492)

The following things have been deprecated and will not be supported in v3.0:
