micromark-util-resolve-all

What is micromark-util-resolve-all?

The micromark-util-resolve-all npm package is a utility library designed to work with the micromark Markdown parser. It provides functionality to resolve all constructs (like tokens and events) in the micromark syntax tree, making it easier to manipulate and transform Markdown documents programmatically. This package is particularly useful for developers working on Markdown processing tools, plugins, or applications that require a deep integration with the Markdown parsing and rendering process.

What are micromark-util-resolve-all's main functionalities?

Resolving constructs

This feature allows you to resolve all constructs in a micromark syntax tree. The code sample demonstrates how to use the `resolveAll` function by passing an array of events (which you would typically get from the micromark parser) and a context object. The function returns a new array of events where all constructs have been resolved, making it easier to further process or manipulate the Markdown document.

"use strict";

var resolveAll = require('micromark-util-resolve-all');

var events = [/* an array of events from micromark */];
var context = {/* some context */};

var resolvedEvents = resolveAll(events, context);

Other packages similar to micromark-util-resolve-all

remark-parse

remark-parse is a plugin for the remark Markdown processor that parses Markdown content into a syntax tree. While it serves a similar purpose in parsing Markdown, remark-parse is part of the unified.js ecosystem and focuses more on the parsing aspect, providing a higher-level abstraction compared to micromark-util-resolve-all, which is more focused on resolving constructs within the micromark syntax tree.

markdown-it

markdown-it is a fast and extensible Markdown parser and renderer. It is similar to micromark-util-resolve-all in that it allows for detailed manipulation and extension of the Markdown parsing process. However, markdown-it is a complete Markdown processing solution, offering both parsing and rendering capabilities out of the box, whereas micromark-util-resolve-all is a utility library designed to work within the micromark ecosystem for resolving constructs.

README

micromark-util-resolve-all

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.

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.
