API

This package exports no identifiers. It exports no additional TypeScript types. The default export is remarkLintNoBlockquoteWithoutMarker.

unified().use(remarkLintNoBlockquoteWithoutMarker)

Warn for lazy lines in block quotes.

Parameters

There are no options.

Returns

Transform (Transformer from unified).

Recommendation

Rules around lazy lines are not straightforward and visually confusing, so it’s recommended to start each line with a >.

Fix

remark-stringify adds > markers to every line in a block quote.

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-no-blockquote-without-marker@6, compatible with Node.js 16.
