unified().use(remarkLintListItemBulletIndent)

Warn when list item markers are indented.

Parameters

There are no options.

Returns

Transform (Transformer from unified).

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. One
 10. Ten
100. Hundred

…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-stringify formats all items without indent.

Examples

ok.md
In
Paragraph.

* List item
* List item
Out

No messages.

not-ok.md
In
Paragraph.

␠* List item
␠* List item
Out
3:2: Incorrect indentation before bullet: remove 1 space
4:2: Incorrect indentation before bullet: remove 1 space

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@4, compatible with Node.js 12.
