Warn when shortcut reference images are used.

There are no options.

Returns

Transform (Transformer from unified).

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. So 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

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-shortcut-reference-image@3, compatible with Node.js 12.
