PresetSetting

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-shortcut-reference-image

In Deno with esm.sh:

import remarkLintNoShortcutReferenceImage from 'https://esm.sh/remark-lint-no-shortcut-reference-image@3'

In browsers with esm.sh:

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

main()

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

  console.error(reporter(file))
}

On the CLI:

remark --use remark-lint --use remark-lint-no-shortcut-reference-image example.md

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

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

API

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

unified().use(remarkLintNoShortcutReferenceImage[, 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

Shortcut references use an implicit style that looks a lot like something that could occur as plain text instead of syntax. In some cases, plain text is intended instead of an image. Due to this, it’s recommended to use collapsed (or full) references instead.

Examples

ok.md
In
![foo][]

[foo]: http://foo.bar/baz.png
Out

No messages.

not-ok.md
In
![foo]

[foo]: http://foo.bar/baz.png
Out
1:1-1:7: Use the trailing [] on reference images
