enforce linebreaks after opening and before closing link brackets

  • ⚙️ This rule is included in plugin.configs.standard.
  • 🔧 The --fix option on the command line can automatically fix some of the problems reported by this rule.

📖 Rule Details ​

This rule enforces consistent linebreaks (newlines) immediately after the opening and/or before the closing brackets of links, images, link references, image references, and link definitions in Markdown documents. It helps maintain a uniform style for link and image syntax, improving readability and reducing accidental formatting inconsistencies.

What Does This Rule Check? ​

  • Links: Checks for linebreaks just after [ and just before ] in inline links, e.g., [label](/url).
  • Images: Checks for linebreaks just after ![ and just before ] in images, e.g., ![label](/url).
  • Link References: Checks for linebreaks in [label][ref] and [label][].
  • Image References: Checks for linebreaks in ![label][ref] and ![label][].
  • Link Definitions: Checks for linebreaks in [label]: /url.

Why Is This Important? ​

Consistent bracket linebreaks:

  • Make Markdown easier to read and maintain.
  • Prevent accidental formatting issues, especially when editing or copying links/images.
  • Align with team or project style preferences.

How Does It Work? ​

  • By default, the rule is set to newline: "never", disallowing linebreaks just inside the brackets.
  • You can set it to newline: "always" to require a linebreak after the opening and before the closing bracket.
  • With newline: "consistent", the rule enforces consistency within each bracketed label.
  • The multiline option allows you to require linebreaks only for multi-line labels.

When Should You Use This Rule? ​

  • When you want all Markdown links and images to have a consistent bracket linebreak style.
  • When enforcing a style guide for documentation or collaborative writing.

Examples ​

With never Option (Default) ​

md
<!-- eslint markdown-preferences/link-bracket-newline: 'error' -->

<!-- ✓ GOOD -->

[foo](/url)
![foo](/url)
[foo][ref]

[ref]: /url

<!-- ✗ BAD -->

[

  foo

](/url)
![

  foo

](/url)
[foo][

   ref

  ]

[

 ref

 ]: /url

🔧 Options ​

json
{
  "markdown-preferences/link-bracket-newline": [
    "error",

      "newline": "never", // or "always" or "consistent"
      "multiline": false
    }
  ]
}
  • newline:
    • "never" (Default) - No linebreaks allowed just inside the brackets.
    • "always" - Linebreaks required just inside the brackets.
    • "consistent" - Enforces consistency within each label.
  • multiline:
    • false (Default) - Always apply the rule.
