MarkupParserclass

new MarkupParser({ rules = MARKUP_RULES, rel, url, root, schemes = HTTP_SCHEMES, context = "block", depth = 0 }: MarkupOptions = {})

Param	Type
`options`	`MarkupOptions`	Options configuring a MarkupParser (represents the current state of the parsing). Defaults to `{}`
`.rules`	`MarkupRules`	The active list of parsing rules. Defaults to `MARKUP_RULES` readonly
`.rel`	`string`	Set the `rel=""` property used for any links (e.g. `rel="nofollow ugc"`). readonly
`.url`	`ImmutableURL`	Current page URL — used as the base for resolving relative refs (`./foo`, `#x`, bare segments) in link hrefs. readonly
`.root`	`ImmutableURL`	Site root URL — used as the base for resolving site-absolute path hrefs (`/foo`), honoring its subfolder. readonly
`.schemes`	`URISchemes`	Valid URI schemes/protocols for URLs and URIs. Defaults to `["http:", "https:"]` readonly
`.context`	`string`	Default context to use if one isn't set. Defaults to `"block"` readonly
`.depth`	`number`	Current nesting depth — used to cap self-recursive rules (e.g. blockquotes) so pathological input can't overflow the stack. Internal: set automatically as rules recurse via `MarkupParser.nested()`; callers normally leave it at the default `0`. Defaults to `0` readonly

Return
`MarkupParser`	Parses a Markdownish markup string and renders it as a React node using a tiered, masking rule engine.

Property	Type
`.rules`	`MarkupRules`	The list of parsing rules this parser applies. required readonly
`.priorities`	`ImmutableArray<number>`	Calculated list of priorities to iterate over (extracted from the rules), e.g. [10, 0, -10] required readonly
`.rel`	`string`	Set the `rel=""` property used for any links (e.g. `rel="nofollow ugc"`). readonly
`.url`	`ImmutableURL`	Current page URL — used as the base for resolving relative refs (`./foo`, `#x`, bare segments) in link hrefs. Falls back to `root` if not set. readonly
`.root`	`ImmutableURL`	Site root URL — used as the base for resolving site-absolute path hrefs (`/foo`), honoring its subfolder. Falls back to `url` if not set. readonly
`.schemes`	`URISchemes`	Valid URI schemes/protocols for URLs and URIs. Defaults to `["http:", "https:"]` readonly
`.context`	`string`	Default context to use if one isn't set. Defaults to `"block"` required readonly
`.depth`	`number`	Current nesting depth, incremented by `nested()` as self-recursive rules descend. Used to cap recursion so pathological input (e.g. a long `>>>>…` blockquote) can't overflow the stack. required readonly

Parses a Markdownish markup string and renders it as a React node using a tiered, masking rule engine.

The syntax isn't hardcoded — it's defined entirely by the rules supplied (defaults to MARKUP_RULES).
Rules are grouped into priority tiers and resolved highest tier first; a claimed region is masked so lower-priority rules can't match into or across it.
Rules own the recursion into their own children by calling parse() again, optionally with a different context.

Methods

Return a copy of this parser with depth incremented by one, sharing all other options.

nested(): MarkupParser

Parse a text string as Markdownish markup syntax and render it as a React node.

parse(input: string, context = this.context): ReactNode

Yield the rules active in context that sit in the given priority tier.

getRules(context: string, priority: number): Iterable<MarkupRule>

Resolve a link href against this parser's url and root, returning it only if its scheme is allowed.

getLink(href: Nullish<PossibleLink>): ImmutableURI | undefined
