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

Warn when ordered list values are inconsistent.
Parameters
— preferred style
Returns
Transform (Transformer from unifiedgithub-unified-transformer).

Options

Configuration (TypeScript type).
consistent looks at the first list with two or more items, and infer 'single' if both are the same, and 'ordered' otherwise.
Type
type Options = Style | 'consistent'

Style

Counter style (TypeScript type).
  • 'one'
— values should always be exactly 1
  • 'ordered'
— values should increment by one from the first item
  • 'single'
— values should stay the same as the first item
Type
type Style = 'one' | 'ordered' | 'single'

Recommendation

While 'single' might be the smartest style, as it makes it easier to move items around without having to renumber everything and doesn’t have problems with aligning content of the 9th and the 10th item, it’s not used a lot and arguably looks unnatural. 'one' is like 'single' but forces every list to start at 1. While not often needed, starting lists at other values is sometimes useful. So 'ordered' is recommended, although 'single' is also a viable choice.

Fix

remark-stringifygithub-remark-stringify retains the value of the first item and increments further items by default. Pass incrementListMarker: false to not increment further items.

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-ordered-list-marker-value@4, compatible with Node.js 16.
