This package exports no identifiers.
It exports the TypeScript types
Options
and
Styles
.
The default export is
remarkLintCheckboxCharacterStyle
.
unified().use(remarkLintCheckboxCharacterStyle[, options])
Warn when list item checkboxes violate a given style.
Parameters
options
(Options
, default:'consistent'
) — either preferred values or whether to detect the first styles and warn for further differences
Returns
Transform (Transformer
from unified
).
Options
Configuration (TypeScript type).
Type
type Options = Styles | 'consistent'
Styles
Styles (TypeScript type).
Fields
checked
('X'
,'x'
, or'consistent'
, default:'consistent'
) — preferred style to use for checked checkboxesunchecked
('␉'
(a tab),'␠'
(a space), or'consistent'
, default:'consistent'
) — preferred style to use for unchecked checkboxes
Recommendation
It’s recommended to set options.checked
to 'x'
(a lowercase X) as it
prevents an extra keyboard press and options.unchecked
to '␠'
(a space)
to make all checkboxes align.
Fix
remark-stringify
formats checked checkboxes
using 'x'
(lowercase X) and unchecked checkboxes using '␠'
(a 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-checkbox-character-style@4
,
compatible with Node.js 12.
