Non-pandoc extensions
The following Markdown syntax extensions are not enabled by default in pandoc, but may be enabled by adding +EXTENSION to the format name, where EXTENSION is the name of the extension. Thus, for example, markdown+hard_line_breaks is Markdown with hard line breaks.
Extension: old_dashes
Selects the pandoc <= 1.8.2.1 behavior for parsing smart dashes: - before a numeral is an en-dash, and -- is an em-dash. This option only has an effect if smart is enabled. It is selected automatically for textile input.
Extension: angle_brackets_escapable
Allow < and > to be backslash-escaped, as they can be in GitHub flavored Markdown but not original Markdown. This is implied by pandoc's default all_symbols_escapable.
Extension: lists_without_preceding_blankline
Allow a list to occur right after a paragraph, with no intervening blank space.
Extension: four_space_rule
Selects the pandoc <= 2.0 behavior for parsing lists, so that four spaces indent are needed for list item continuation paragraphs.
Extension: spaced_reference_links
Allow whitespace between the two components of a reference link, for example,
[foo] [bar].
Extension: hard_line_breaks
Causes all newlines within a paragraph to be interpreted as hard line breaks instead of spaces.
Extension: ignore_line_breaks
Causes newlines within a paragraph to be ignored, rather than being treated as spaces or as hard line breaks. This option is intended for use with East Asian languages where spaces are not used between words, but text is divided into lines for readability.
Extension: east_asian_line_breaks
Causes newlines within a paragraph to be ignored, rather than being treated as spaces or as hard line breaks, when they occur between two East Asian wide characters. This is a better choice than ignore_line_breaks for texts that include a mix of East Asian wide characters and other characters.
Extension: emoji
Parses textual emojis like :smile: as Unicode emoticons.
Extension: tex_math_single_backslash
Causes anything between \( and \) to be interpreted as inline TeX math, and anything between \[ and \] to be interpreted as display TeX math. Note: a drawback of this extension is that it precludes escaping ( and [.
Extension: tex_math_double_backslash
Causes anything between \\( and \\) to be interpreted as inline TeX math, and anything between \\[ and \\] to be interpreted as display TeX math.
Extension: markdown_attribute
By default, pandoc interprets material inside block-level tags as Markdown. This extension changes the behavior so that Markdown is only parsed inside block-level tags if the tags have the attribute markdown=1.
Extension: mmd_title_block
Enables a MultiMarkdown style title block at the top of the document, for example:
Title: My title
Author: John Doe
Date: September 1, 2008
Comment: This is a sample mmd title block, with
a field spanning multiple lines.
See the MultiMarkdown documentation for details. If pandoc_title_block or yaml_metadata_block is enabled, it will take precedence over mmd_title_block.
Extension: abbreviations
Parses PHP Markdown Extra abbreviation keys, like
*[HTML]: Hypertext Markup Language
Note that the pandoc document model does not support abbreviations, so if this extension is enabled, abbreviation keys are simply skipped (as opposed to being parsed as paragraphs).
Extension: autolink_bare_uris
Makes all absolute URIs into links, even when not surrounded by pointy braces <...>.
Extension: mmd_link_attributes
Parses multimarkdown style key-value attributes on link and image references. This extension should not be confused with the link_attributes extension.
This is a reference ![image][ref] with multimarkdown attributes.
[ref]: http://path.to/image "Image title" width=20px height=30px
id=myId class="myClass1 myClass2"
Parses multimarkdown style heading identifiers (in square brackets, after the heading but before any trailing #s in an ATX heading).
Extension: compact_definition_lists
Activates the definition list syntax of pandoc 1.12.x and earlier. This syntax differs from the one described above under Definition lists in several respects:
- No blank line is required between consecutive items of the definition list.
- To get a "tight" or "compact" list, omit space between consecutive items; the space between a term and its definition does not affect anything.
- Lazy wrapping of paragraphs is not allowed: the entire definition must be indented four spaces.
