API Reference

markdown(config⁠?: Object = {}) → LanguageSupport

Markdown language support.

config

defaultCodeLanguage⁠?: Language | LanguageSupport

When given, this language will be used by default to parse code blocks.

codeLanguages⁠?: readonly LanguageDescription[]

A collection of language descriptions to search through for a matching language (with LanguageDescription.matchLanguageName) when a fenced code block has an info string.

addKeymap⁠?: boolean

Set this to false to disable installation of the Markdown keymap.

extensions⁠?: MarkdownExtension

Markdown parser extensions to add to the parser.

base⁠?: Language

The base language to use. Defaults to commonmarkLanguage.

markdownLanguage: Language

Language support for GFM plus subscript, superscript, and emoji syntax.

commonmarkLanguage: Language

Language support for strict CommonMark.

insertNewlineContinueMarkup: StateCommand

This command, when invoked in Markdown context with cursor selection(s), will create a new line with the markup for blockquotes and lists that were active on the old line. If the cursor was directly after the end of the markup for the old line, trailing whitespace and list markers are removed from that line.

The command does nothing in non-Markdown context, so it should not be used as the only binding for Enter (even in a Markdown document, HTML and code regions might use a different language).

deleteMarkupBackward: StateCommand

This command will, when invoked in a Markdown context with the cursor directly after list or blockquote markup, delete one level of markup. When the markup is for a list, it will be replaced by spaces on the first invocation (a further invocation will delete the spaces), to make it easy to continue a list.

When not after Markdown block markup, this command will return false, so it is intended to be bound alongside other deletion commands, with a higher precedence than the more generic commands.

markdownKeymap: readonly KeyBinding[]

A small keymap with Markdown-specific bindings. Binds Enter to insertNewlineContinueMarkup and Backspace to deleteMarkupBackward.
