Properties

dependencies

dependencies: Klass<LexicalNode>[]

Defined in: packages/lexical-markdown/src/MarkdownTransformers.ts:58

export

export: (node, traverseChildren) => string | null

Defined in: packages/lexical-markdown/src/MarkdownTransformers.ts:64

export is called when the $convertToMarkdownString is called to convert the editor state into markdown.

Parameters

node

LexicalNode

traverseChildren

(node) => string

Returns

string | null

return null to cancel the export, even though the regex matched. Lexical will then search for the next transformer.

regExp

regExp: RegExp

Defined in: packages/lexical-markdown/src/MarkdownTransformers.ts:69

replace

replace: (parentNode, children, match, isImport) => boolean | void

Defined in: packages/lexical-markdown/src/MarkdownTransformers.ts:75

replace is called when markdown is imported or typed in the editor

Parameters

parentNode

ElementNode

children

LexicalNode[]

match

string[]

isImport

boolean

Returns

boolean | void

return false to cancel the transform, even though the regex matched. Lexical will then search for the next transformer.

Properties

export?

optional export?: (node, traverseChildren) => string | null

Defined in: packages/lexical-markdown/src/MarkdownTransformers.ts:107

export is called when the $convertToMarkdownString is called to convert the editor state into markdown.

Parameters

node

LexicalNode

traverseChildren

(node) => string

Returns

string | null

return null to cancel the export, even though the regex matched. Lexical will then search for the next transformer.

handleImportAfterStartMatch?

optional handleImportAfterStartMatch?: (args) => [boolean, number] | null | undefined

Defined in: packages/lexical-markdown/src/MarkdownTransformers.ts:94

Use this function to manually handle the import process, once the regExpStart has matched successfully. Without providing this function, the default behavior is to match until regExpEnd is found, or until the end of the document if regExpEnd.optional is true.

Parameters

args

lines

string[]

rootNode

ElementNode

startLineIndex

number

startMatch

RegExpMatchArray

transformer

MultilineElementTransformer

Returns

[boolean, number] | null | undefined

a tuple or null. The first element of the returned tuple is a boolean indicating if a multiline element was imported. The second element is the index of the last line that was processed. If null is returned, the next multilineElementTransformer will be tried. If undefined is returned, the default behavior will be used.

regExpEnd?

optional regExpEnd?: RegExp | { optional?: true; regExp: RegExp; }

Defined in: packages/lexical-markdown/src/MarkdownTransformers.ts:119

This regex determines when to stop matching. Anything in between regExpStart and regExpEnd will be matched

Union Members

RegExp

---

Type Literal

{ optional?: true; regExp: RegExp; }

optional?

optional optional?: true

Whether the end match is optional. If true, the end match is not required to match for the transformer to be triggered. The entire text from regexpStart to the end of the document will then be matched.

regExp

regExp: RegExp

regExpStart

regExpStart: RegExp

Defined in: packages/lexical-markdown/src/MarkdownTransformers.ts:115

This regex determines when to start matching

replace

replace: (rootNode, children, startMatch, endMatch, linesInBetween, isImport) => boolean | void

Defined in: packages/lexical-markdown/src/MarkdownTransformers.ts:134

replace is called only when markdown is imported in the editor, not when it's typed

Parameters

rootNode

ElementNode

children

LexicalNode[] | null

startMatch

string[]

endMatch

string[] | null

linesInBetween

string[] | null

isImport

boolean

Returns

boolean | void

return false to cancel the transform, even though the regex matched. Lexical will then search for the next transformer.
