What is this?

This package is a unified (remark) plugin, specifically a remark-lint rule. Lint rules check markdown code style.

When should I use this?

You can use this package to check that unordered list markers (bullets) are consistent.

Presets

This rule is included in the following presets:
| Preset | Setting | | - | - | | remark-preset-lint-markdown-style-guide | '-' |

Install

This package is ESM onlyesm. In Node.js (version 12.20+, 14.14+, or 16.0+), install with npm:

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

In Deno with Skypack:

import remarkLintUnorderedListMarkerStyle from 'https://cdn.skypack.dev/remark-lint-unordered-list-marker-style@3?dts'

In browsers with Skypack:

<script type="module">
  import remarkLintUnorderedListMarkerStyle from 'https://cdn.skypack.dev/remark-lint-unordered-list-marker-style@3?min'
</script>

Use

On the API:

import {read} from 'to-vfile'
import {reporter} from 'vfile-reporter'
import {remark} from 'remark'
import remarkLint from 'remark-lint'
import remarkLintUnorderedListMarkerStyle from 'remark-lint-unordered-list-marker-style'

main()

async function main() {
  const file = await remark()
    .use(remarkLint)
    .use(remarkLintUnorderedListMarkerStyle)
    .process(await read('example.md'))

  console.error(reporter(file))
}

On the CLI:

remark --use remark-lint --use remark-lint-unordered-list-marker-style example.md

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. The default export is remarkLintUnorderedListMarkerStyle.

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

This rule supports standard configuration that all remark lint rules accept (such as false to turn it off or [1, options] to configure it).
The following options (default: 'consistent') are accepted:

• '*'

— prefer asterisks

• '+'

— prefer plusses

• '-'

— prefer dashes

• 'consistent'

— detect the first used style and warn when further markers differ

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 ordered lists with asterisks by default. Pass bullet: '+' or bullet: '-' to always use plusses or dashes.

Examples

ok.md

In

By default (`'consistent'`), if the file uses only one marker,
that’s OK.

* Foo
* Bar
* Baz

Ordered lists are not affected.

1. Foo
2. Bar
3. Baz

Out

No messages.

not-ok.md

In

* Foo
- Bar
+ Baz

Out

2:1-2:6: Marker style should be `*`
3:1-3:6: Marker style should be `*`

ok.md

When configured with '*'.

In

* Foo

Out

No messages.

ok.md

When configured with '-'.

In

- Foo

Out

No messages.

ok.md

When configured with '+'.

In

+ Foo

Out

No messages.

not-ok.md

When configured with '💩'.

Out

1:1: Incorrect unordered list item marker style `💩`: use either `'-'`, `'*'`, or `'+'`

Compatibility

Projects maintained by the unified collective are compatible with all maintained versions of Node.js. As of now, that is Node.js 12.20+, 14.14+, and 16.0+. Our projects sometimes work with older versions, but this is not guaranteed.
