remark-lint-checkbox-character-style

remark-lint-checkbox-character-style

Warn when list item checkboxes violate a given style.

Options: Object or 'consistent', default: 'consistent'.

'consistent' detects the first used checked and unchecked checkbox styles and warns when subsequent checkboxes use different styles.

Styles can also be passed in like so:

{ checked: 'x', unchecked: ' ' }

Fix

remark-stringify formats checked checkboxes using x and unchecked checkboxes as ``.

See Using remark to fix your markdown on how to automatically fix warnings for this rule.
