API

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

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

Warn when unordered list markers are inconsistent.

Parameters
Returns

Transform (Transformer from unified).

Marker

Marker (TypeScript type).

Type
type Marker = '*' | '+' | '-'

Options

Configuration (TypeScript type).

Type
type Options = Marker | 'consistent'

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.

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.

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
In
* Foo
- Bar
+ Baz
Out
2:1-2:6: Marker style should be `*`
3:1-3:6: Marker style should be `*`
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 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@3, compatible with Node.js 12.
