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 collapsed reference images are used instead of full references where possible.

Presets

This rule is not included in a preset maintained here.

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-unneeded-full-reference-image

In Deno with esm.sh:

import remarkLintNoUnneededFullReferenceImage from 'https://esm.sh/remark-lint-no-unneeded-full-reference-image@3'

In browsers with esm.sh:

<script type="module">
  import remarkLintNoUnneededFullReferenceImage from 'https://esm.sh/remark-lint-no-unneeded-full-reference-image@3?bundle'
</script>

Use

On the API:

import {remark} from 'remark'
import remarkLint from 'remark-lint'
import remarkLintNoUnneededFullReferenceImage from 'remark-lint-no-unneeded-full-reference-image'
import {read} from 'to-vfile'
import {reporter} from 'vfile-reporter'

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

await remark()
  .use(remarkLint)
  .use(remarkLintNoUnneededFullReferenceImage)
  .process(file)

console.error(reporter(file))

On the CLI:

remark --use remark-lint --use remark-lint-no-unneeded-full-reference-image example.md

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

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

API

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

`unified().use(remarkLintNoUnneededFullReferenceImage[, 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

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

Examples

`ok.md`

In

![alpha][]
![Bravo][]
![Charlie][delta]

[alpha]: a
[bravo]: b
[delta]: d

Out

No messages.

`not-ok.md`

In

![alpha][alpha]
![Bravo][bravo]
![charlie][Charlie]

[alpha]: a
[bravo]: b
[charlie]: c

Out

1:1-1:16: Remove the image label as it matches the reference text
2:1-2:16: Remove the image label as it matches the reference text
3:1-3:20: Remove the image label as it matches the reference text
