What is this?

This package checks the “indent” of block quotes: the > (greater than) marker and the spaces before content.

When should I use this?

You can use this rule to check markdown code style.

Presets

This plugin is included in the following presets:
| Preset | Options | | - | - | | remark-preset-lint-consistent | 'consistent' | | remark-preset-lint-markdown-style-guide | 2 |

Install

This package is ESM onlygithub-gist-esm. In Node.js (version 16+), install with npmnpm-install:

npm install remark-lint-blockquote-indentation

In Deno with esm.shesm-sh:

import remarkLintBlockquoteIndentation from 'https://esm.sh/remark-lint-blockquote-indentation@4'

In browsers with esm.shesm-sh:

<script type="module">
  import remarkLintBlockquoteIndentation from 'https://esm.sh/remark-lint-blockquote-indentation@4?bundle'
</script>

Use

On the API:

import remarkLint from 'remark-lint'
import remarkLintBlockquoteIndentation from 'remark-lint-blockquote-indentation'
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(remarkLintBlockquoteIndentation)
  .use(remarkStringify)

    "remark-lint",
+    "remark-lint-blockquote-indentation",
    …
  ]
}
…

API

This package exports no identifiers. It exports the TypeScripttypescript type Optionsapi-options. The default export is remarkLintBlockquoteIndentationapi-remark-lint-blockquote-indentation.

unified().use(remarkLintBlockquoteIndentation[, options])

Warn when block quotes are indented too much or too little.

Parameters

• options (Optionsapi-options, default: 'consistent')

— either a preferred indent or whether to detect the first style and warn for further differences

Returns

Transform (Transformer from unifiedgithub-unified-transformer).

Options

Configuration (TypeScript type).

Type

type Options = number | 'consistent'

Recommendation

CommonMark specifies that when block quotes are used the > markers can be followed by an optional space. No space at all arguably looks rather ugly:

>Mars and
>Venus.

There is no specific handling of more that one space, so if 5 spaces were used after >, then indented code kicks in:

>     neptune()

Due to this, it’s recommended to configure this rule with 2.

Examples

ok-2.md

When configured with 2.

In

> Mercury.

Venus.

> Earth.

Out

No messages.

ok-4.md

No messages.

ok-tab.md

In

>␉Mercury.

Out

No messages.

not-ok.md

In

>  Mercury.

Venus.

>   Earth.

Mars.

> Jupiter

Out

5:5: Unexpected `4` spaces between block quote marker and content, expected `3` spaces, remove `1` space
9:3: Unexpected `2` spaces between block quote marker and content, expected `3` spaces, add `1` space

not-ok-options.md

When configured with '🌍'.

Out

1:1: Unexpected value `🌍` for `options`, expected `number` or `'consistent'`

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-blockquote-indentation@4, compatible with Node.js 16.
