API

unified().use(remarkLintCheckboxContentIndent)

Warn when GFM tasklist checkboxes are followed by more than one space.

Parameters

There are no options.

Returns

Transform (Transformer from unified).

Recommendation

GFM allows zero or more spaces and tabs after checkboxes. No space at all arguably looks rather ugly:

* [x]Pluto

More that one space is superfluous:

* [x]   Jupiter

Due to this, it’s recommended to turn this rule on.

Fix

remark-stringify formats checkboxes and the content after them with a single space between.
