What is this?

This package exposes states to parse whitespace.

When should I use this?

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

Install

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

npm install micromark-factory-whitespace

In Deno with [esm.sh][esmsh]:

import {factoryWhitespace} from 'https://esm.sh/micromark-factory-whitespace@1'

In browsers with [esm.sh][esmsh]:

Use

import {factoryWhitespace} from 'micromark-factory-whitespace'
import {codes, types} from 'micromark-util-symbol'
// A micromark tokenizer that uses the factory:
/**
 * @this {TokenizeContext}
 *   Context.
 * @type {Tokenizer}
 */
function tokenizeTitle(effects, ok, nok) {
  return start
  /* @type {State} /
  function start(code) {
    return markdownLineEndingOrSpace(code)
      ? factoryWhitespace(effects, before)(code)
      : nok(code)
  }  // …
}

API

This module exports the identifier [factoryWhitespace][api-factory-whitespace]. There is no default export.

`factoryWhitespace(…)`

Parse spaces and tabs.

There is no nok parameter:

* line endings or spaces in markdown are often optional, in which case this factory can be used and ok will be switched to whether spaces were found or not * one line ending or space can be detected with [markdownLineEndingOrSpace(code)][ws] right before using factoryWhitespace

###### Parameters

* effects (Effects) — context * ok (State) — state switched to when successful

###### Returns

Start state (State).

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-factory-whitespace@2, compatible with Node.js 16. This package works with micromark@3.

Security

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

Contribute

See [contributing.md][contributing] in [micromark/.github][health] for ways to get started. See [support.md][support] for ways to get help.
