What is this?

This package exposes states to parse spaces and/or tabs.

When should I use this?

This package is 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-factory-space

In Deno with esm.sh:

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

In browsers with esm.sh:

<script type="module">
  import {factorySpace} from 'https://esm.sh/micromark-factory-space@1?bundle'
</script>

Use

import {factorySpace} from 'micromark-factory-space'
import {codes, types} from 'micromark-util-symbol'

// A micromark tokenizer that uses the factory:
/**
 * @this {TokenizeContext}
 * @type {Tokenizer}
 */
function tokenizeCodeFenced(effects, ok, nok) {
  return start

  // …

  /** @type {State} */
  function info(code) {
    if (code === codes.eof || markdownLineEndingOrSpace(code)) {
      effects.exit(types.chunkString)
      effects.exit(types.codeFencedFenceInfo)
      return factorySpace(effects, infoAfter, types.whitespace)(code)
    }

    if (code === codes.graveAccent && code === marker) return nok(code)
    effects.consume(code)
    return info
  }

  // …
}

API

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

factorySpace(…)

Parse spaces and tabs.

There is no nok parameter:

• 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 markdownSpace(code) right before using factorySpace

Examples

Where ␉ represents a tab (plus how much it expands) and ␠ represents a single space.

␉
␠␠␠␠
␉␠

Parameters

• effects (Effects) — context
• ok (State) — state switched to when successful
• type (string) — type (' \t')
• max (number, default: Infinity) — max (exclusive)

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-space@^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.
