Markdown parser for the initial markdown spec.

Cloneable Instantiable
public $html5
  • var bool whether to format markup according to HTML5 spec. Defaults to `false` which means that markup is formatted as HTML4.
public $keepListStartNumber
  • var bool enable support `start` attribute of ordered lists. This means that lists will start with the number you actually type in markdown and not the HTML generated one. Defaults to `false` which means that numeration of all ordered lists(
      ) starts with 1.
public cebe\markdown\Parser :: $maximumNestingLevel
  • var int the maximum nesting level for language elements.
public cebe\markdown\Parser :: parse ( $text )

Parses the given text considering the full language.

This includes parsing block elements as well as inline elements.

  • return string parsed markup
public cebe\markdown\Parser :: parseParagraph ( $text )

Parses a paragraph without block elements (block elements are ignored).

  • return string parsed markup
protected cebe\markdown\Parser :: $context
  • var array the current context the parser is in. TODO remove in favor of absy
protected $escapeCharacters
  • var array these are "escapeable" characters. When using one of these prefixed with a backslash, the character will be outputted without the backslash and is not interpreted as markdown.
protected $inlineHtmlElements
  • var array HTML elements considered as inline elements.
  • see
protected $references
  • var array a list of defined references in this document.
protected $selfClosingHtmlElements
  • var array HTML elements known to be self-closing.
protected cebe\markdown\Parser :: blockTypes ()
  • return array a list of block element types available.
protected cebe\markdown\Parser :: cleanup ()

This method will be called after parse() and parseParagraph().

You can override it to do cleanup.

protected consumeAHr ( $lines , $current )

Consume a horizontal rule

protected consumeBUl ( $lines , $current )

Consume lines for an unordered list

protected consumeCode ( $lines , $current )

protected consumeOl ( $lines , $current )

Allow headlines and code to break paragraphs

protected consumeQuote ( $lines , $current )

Consume lines for a blockquote element

protected consumeReference ( $lines , $current )

protected consumeUl ( $lines , $current )

protected cebe\markdown\Parser :: detectLineType ( $lines , $current )

Given a set of lines and an index of a current line it uses the registed block types to
detect the type of this line.

  • return string name of the block type in lower case
protected identifyAHr ( $line )

identify a line as a horizontal rule.

protected identifyBUl ( $line )

protected identifyReference ( $line )
protected identifyUl ( $line )

protected cebe\markdown\Parser :: inlineMarkers ()

Returns a map of inline markers to the corresponding parser methods.

This array defines handler methods for inline markdown markers.
When a marker is found in the text, the handler method is called with the text
starting at the position of the marker.

Note that markers starting with whitespace may slow down the parser,
you may want to use [[renderText]] to deal with them.

You may override this method to define a set of markers and parsing methods.
The default implementation looks for protected methods starting with parse that
also have an @marker annotation in PHPDoc.

  • return array a map of markers to parser methods
protected lookupReference ( $key )
protected cebe\markdown\Parser :: parseBlock ( $lines , $current )

Parses the block at current line by identifying the block type and parsing the content

  • return array Array of two elements, the first element contains the block, the second contains the next line index to be parsed.
protected cebe\markdown\Parser :: parseBlocks ( $lines )

Parse block elements by calling detectLineType() to identify them
and call consume function afterwards.

protected parseEmphStrong ( $text )

Parses emphasized and strong elements.

  • marker _
  • marker *
protected parseEntity ( $text )

Parses an & or a html entity definition.

  • marker &
protected cebe\markdown\Parser :: parseEscape ( $text )

  • marker \
protected parseGt ( $text )

  • marker >
protected parseImage ( $markdown )
