micromark utility to resolve subtokens.

Resolvers are functions that take events and manipulate them. This is needed for example because media (links, images) and attention (strong, italic) aren’t parsed left-to-right. Instead, their openings and closings are parsed, and when done, their openings and closings are matched, and left overs are turned into plain text. Because media and attention can’t overlap, we need to perform that operation when one closing matches an opening, too.

What is this?

This package exposes a micromark internal that you probably don’t need.

When should I use this?

This package might be useful when you are making your own micromark extensions.

Install

This package is ESM only. In Node.js (version 16+), install with npm:

npm install micromark-util-resolve-all

In Deno with esm.sh:

import {resolveAll} from 'https://esm.sh/micromark-util-resolve-all@1'

In browsers with esm.sh:

<script type="module">
  import {resolveAll} from 'https://esm.sh/micromark-util-resolve-all@1?bundle'
</script>

Use

import {push} from 'micromark-util-chunked'
import {resolveAll} from 'micromark-util-resolve-all'

/**
 * @type {Resolver}
 */
function resolveAllAttention(events, context) {
  // …

  // Walk through all events.
  while (++index < events.length) {
    // Find a token that can close.
    if (
      events[index][0] === 'enter' &&
      events[index][1].type === 'attentionSequence' &&
      events[index][1]._close
    ) {
      open = index

      // Now walk back to find an opener.
      while (open--) {
        // Find a token that can open the closer.
        if (
          // …
        ) {
          // …

          // Opening.
          nextEvents = push(nextEvents, [
            // …
          ])

          // Between.
          nextEvents = push(
            nextEvents,
            resolveAll(
              context.parser.constructs.insideSpan.null,
              events.slice(open + 1, index),
              context
            )
          )

          // Closing.
          nextEvents = push(nextEvents, [
            // …
          ])

          // …
        }
      }
    }
  }

  // …
}

API

This module exports the identifier resolveAll. There is no default export.

resolveAll(constructs, events, context)

Call all resolveAlls in constructs.

Parameters
  • constructs (Array<Construct>) — list of constructs, optionally with resolveAlls
  • events (Array<Event>) — list of events
  • context (TokenizeContext) — context used by tokenize
Returns

Changed events (Array<Events>).

Types

This package is fully typed with TypeScript. It exports no additional types.

Compatibility

Projects maintained by the unified collective are compatible with maintained versions of Node.js.

When we cut a new major release, we drop support for unmaintained versions of Node. This means we try to keep the current release line, micromark-util-resolve-all@^2, compatible with Node.js 16. This package works with micromark@^3.

Security

This package is safe. See security.md in micromark/.github for how to submit a security report.
