import remarkParse from 'remark-parse'
import remarkStringify from 'remark-stringify'
import {read} from 'to-vfile'

API

This package exports no identifiers.
It exports no additional TypeScript types.
The default export is
remarkLintListItemBulletIndent.

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. 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-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.
