API

This package exports no identifiers. It exports no additional TypeScripttypescript types. The default export is remarkLintListItemBulletIndentapi-remark-lint-list-item-bullet-indent.

unified().use(remarkLintListItemBulletIndent)

Warn when list item markers are indented.

Parameters

There are no options.

Returns

Transform (Transformer from unifiedgithub-unified-transformer).

Recommendation

There is no specific handling of indented list items in markdown. While it is possible to use an indent to align ordered lists on their marker:

1. Mercury
 10. Venus
100. Earth

…such a style is uncommon and hard to maintain as adding a 10th item means 9 other items have to change (more arduous while unlikely would be the 100th item). So it is recommended to not indent items and to turn this rule on.

Fix

remark-stringifygithub-remark-stringify formats all items without indent.

Examples

ok.md

In

Mercury.

* Venus.
* Earth.

Out

No messages.

not-ok.md

In

Mercury.

␠* Venus.
␠* Earth.

Out

3:2: Unexpected `1` space before list item, expected `0` spaces, remove them
4:2: Unexpected `1` space before list item, expected `0` spaces, remove them

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-list-item-bullet-indent@5, compatible with Node.js 16.
