What is this?

This package is a unified (remark) plugin, specifically a remark-lint rule. Lint rules check markdown code style.

When should I use this?

You can use this package to check that lines in block quotes start with >.

Presets

This rule is included in the following presets:

Install

This package is ESM only. In Node.js (version 12.20+, 14.14+, or 16.0+), install with npm:

npm install remark-lint-no-blockquote-without-marker

In Deno with Skypack:

import remarkLintNoBlockquoteWithoutMarker from 'https://cdn.skypack.dev/remark-lint-no-blockquote-without-marker@5?dts'

In browsers with Skypack:

<script type="module">
  import remarkLintNoBlockquoteWithoutMarker from 'https://cdn.skypack.dev/remark-lint-no-blockquote-without-marker@5?min'
</script>

Use

On the API:

import {read} from 'to-vfile'
import {reporter} from 'vfile-reporter'
import {remark} from 'remark'
import remarkLint from 'remark-lint'
import remarkLintNoBlockquoteWithoutMarker from 'remark-lint-no-blockquote-without-marker'

main()

async function main() {
  const file = await remark()
    .use(remarkLint)
    .use(remarkLintNoBlockquoteWithoutMarker)
    .process(await read('example.md'))

  console.error(reporter(file))
}

On the CLI:

remark --use remark-lint --use remark-lint-no-blockquote-without-marker example.md

On the CLI in a config file (here a package.json):

 …
 "remarkConfig": {
   "plugins": [
     …
     "remark-lint",
+    "remark-lint-no-blockquote-without-marker",
     …
   ]
 }
 …

API

This package exports no identifiers. The default export is remarkLintNoBlockquoteWithoutMarker.

unified().use(remarkLintNoBlockquoteWithoutMarker[, config])

This rule supports standard configuration that all remark lint rules accept (such as false to turn it off or [1, options] to configure it).

There are no options.

Recommendation

Rules around “lazy” lines are not straightforward and visually confusing, so it’s recommended to start each line with a >.

Fix

remark-stringify adds > markers to every line in a block quote.

Examples

ok.md

In

> Foo…
> …bar…
> …baz.

Out

No messages.

ok-tabs.md

In

👉 Note: » represents a tab.

>»Foo…
>»…bar…
>»…baz.

Out

No messages.

not-ok.md

In

> Foo…
…bar…
> …baz.

Out

2:1: Missing marker in block quote

not-ok-tabs.md

In

👉 Note: » represents a tab.

>»Foo…
»…bar…
…baz.

Out

2:1: Missing marker in block quote
3:1: Missing marker in block quote
