`

In Deno with [esm.sh][esm-sh]:

Use

On the API:

`js
import remarkLint from 'remark-lint'
import remarkLintOrderedListMarkerStyle from 'remark-lint-ordered-list-marker-style'
import remarkParse from 'remark-parse'
import remarkStringify from 'remark-stringify'
import {read} from 'to-vfile'
import {unified} from 'unified'
import {reporter} from 'vfile-reporter'

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

await unified()
.use(remarkParse)
.use(remarkLint)
.use(remarkLintOrderedListMarkerStyle)
.use(remarkStringify)
.process(file)

console.error(reporter(file))

…
`

API

This package exports no identifiers.
It exports the [TypeScript][typescript] types
[Options][api-options] and
[Style][api-style].
The default export is
[remarkLintOrderedListMarkerStyle][api-remark-lint-ordered-list-marker-style].

$3

Warn when ordered list markers are inconsistent.

###### Parameters

* options ([Options][api-options], default: 'consistent')
— preferred style or whether to detect the first style and warn for
further differences

###### Returns

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

$3

Configuration (TypeScript type).

###### Type

`ts
type Options = Style | 'consistent'
`

$3

Style (TypeScript type).

###### Type

`ts
type Style = '.' | ')'
`

Recommendation

Parens for list markers were not supported in markdown before CommonMark.
While they should work in most places now,
not all markdown parsers follow CommonMark.
So it’s recommended to prefer dots.

Fix

[remark-stringify][github-remark-stringify] formats ordered lists with
dots by default.
Pass bulletOrdered: ')' to always use parens.

Examples

##### ok.md

###### In

`markdown
1. Mercury

* Venus

1. Earth
`

###### Out

No messages.

##### ok.md

When configured with '.'.

###### In

`

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-ordered-list-marker-style@4,
compatible with Node.js 16.
