import remarkParse from 'remark-parse'
import remarkStringify from 'remark-stringify'

import {reporter} from 'vfile-reporter'

const file = await read('example.md')

$3

Warn when list item markers are indented.

###### Parameters

There are no options.

###### Returns

Transform ([Transformer from unified][github-unified-transformer]).

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:

`markdown
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][github-remark-stringify] formats all items without
indent.

Examples

##### ok.md

###### In

`markdown
Mercury.

* Venus.
* Earth.
`

###### Out

No messages.

##### not-ok.md

###### In

`markdown
Mercury.

␠* Venus.
␠* Earth.
`

###### Out

`text
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.
