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.
