What is this?

This package checks unordered list markers.

When should I use this?

You can use this package to check unordered lists.

Presets

This plugin is included in the following presets:

Install

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

npm install remark-lint-unordered-list-marker-style

In Deno with esm.sh:

import remarkLintUnorderedListMarkerStyle from 'https://esm.sh/remark-lint-unordered-list-marker-style@4'

In browsers with esm.sh:

<script type="module">
  import remarkLintUnorderedListMarkerStyle from 'https://esm.sh/remark-lint-unordered-list-marker-style@4?bundle'
</script>

Use

On the API:

import remarkLint from 'remark-lint'
import remarkLintUnorderedListMarkerStyle from 'remark-lint-unordered-list-marker-style'
import remarkParse from 'remark-parse'
import remarkStringify from 'remark-stringify'
import {read} from 'to-vfile'
import {unified} from 'unified'
import {reporter} from 'vfile-reporter'

const file = await read('example.md')

await unified()
  .use(remarkParse)
  .use(remarkLint)
  .use(remarkLintUnorderedListMarkerStyle)
  .use(remarkStringify)
  .process(file)

console.error(reporter(file))

On the CLI:

remark --frail --use remark-lint --use remark-lint-unordered-list-marker-style .

On the CLI in a config file (here a package.json):

 …
 "remarkConfig": {
   "plugins": [
     …
     "remark-lint",
+    "remark-lint-unordered-list-marker-style",
     …
   ]
 }
 …

API

This package exports no identifiers. It exports the TypeScript types Options and Style. The default export is remarkLintUnorderedListMarkerStyle.

unified().use(remarkLintUnorderedListMarkerStyle[, options])

Warn when unordered list markers are inconsistent.

Parameters

• options (Options, default: 'consistent') — preferred style or whether to detect the first style and warn for further differences

Returns

Transform (Transformer from unified).

Options

Configuration (TypeScript type).

Type

type Options = Style | 'consistent'

Style

Style (TypeScript type).

Type

type Style = '*' | '+' | '-'

Recommendation

Because asterisks can be used as a marker for more markdown constructs, it’s recommended to use that for lists (and thematic breaks, emphasis, strong) too.

Fix

remark-stringify formats unordered lists with asterisks by default. Pass bullet: '+' or bullet: '-' to use a different marker.

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, remark-lint-unordered-list-marker-style@4, compatible with Node.js 16.
