This package checks for unneeded full reference links.

When should I use this?

You can use this package to check that reference links are consistent.

Presets

This plugin is not included in presets maintained here.

Install

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

npm install remark-lint-no-unneeded-full-reference-link

In Deno with esm.shesm-sh:

import remarkLintNoUnneededFullReferenceLink from 'https://esm.sh/remark-lint-no-unneeded-full-reference-link@4'

In browsers with esm.shesm-sh:

<script type="module">
  import remarkLintNoUnneededFullReferenceLink from 'https://esm.sh/remark-lint-no-unneeded-full-reference-link@4?bundle'
</script>

Use

On the API:

import remarkLint from 'remark-lint'
import remarkLintNoUnneededFullReferenceLink from 'remark-lint-no-unneeded-full-reference-link'
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(remarkLintNoUnneededFullReferenceLink)
  .use(remarkStringify)
  .process(file)

console.error(reporter(file))

On the CLI:

remark --frail --use remark-lint --use remark-lint-no-unneeded-full-reference-link .

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

…
"remarkConfig": {
  "plugins": [
    …
    "remark-lint",
+    "remark-lint-no-unneeded-full-reference-link",
    …
  ]
}
…

API

This package exports no identifiers. It exports no additional TypeScripttypescript types. The default export is remarkLintNoUnneededFullReferenceLinkapi-remark-lint-no-unneeded-full-reference-link.

unified().use(remarkLintNoUnneededFullReferenceLink)

Warn when unneeded full reference links are used.

Parameters

There are no options.

Returns

Transform (Transformer from unifiedgithub-unified-transformer).

Recommendation

Full reference syntax ([Text][text]) is quite verbose compared to the concise collapsed reference syntax ([Text][]).

Examples

ok.md

In

[Mercury][] and [Venus][venus-url].

Out

No messages.

not-ok.md

In

[Mercury][mercury].

Out

1:1-1:19: Unexpected full reference link (`[text][label]`) where the identifier can be inferred from the text, expected collapsed reference (`[text][]`)

escape.md

In

👉 Note: this example uses GFM (remark-gfmgithub-remark-gfm).

Matrix:

| Kind                      | Text normal | Text escape  | Text character reference |
| ------------------------- | ----------- | ------------ | ------------------------ |
| Label normal              | [&][&]      | [\&][&]      | [&][&]               |
| Label escape              | [&][\&]     | [\&][\&]     | [&][\&]              |
| Label character reference | [&][&]  | [\&][&]  | [&][&]           |

When using the above matrix, the first row will go to `a`, the second
to `b`, third to `c`.
Removing all labels, you’d instead get it per column: `a`, `b`, `c`.
That shows the label is not needed when it matches the text, and is otherwise.

Out

5:31-5:37: Unexpected full reference link (`[text][label]`) where the identifier can be inferred from the text, expected collapsed reference (`[text][]`)
6:45-6:53: Unexpected full reference link (`[text][label]`) where the identifier can be inferred from the text, expected collapsed reference (`[text][]`)
7:60-7:74: Unexpected full reference link (`[text][label]`) where the identifier can be inferred from the text, expected collapsed reference (`[text][]`)

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-no-unneeded-full-reference-link@4, compatible with Node.js 16.
