    remark-lint rule to warn when URLs are defined multiple times.

    Contents

    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 URLs are defined once.

    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-duplicate-defined-urls

    In Deno with Skypack:

    import remarkLintNoDuplicateDefinedUrls from 'https://cdn.skypack.dev/remark-lint-no-duplicate-defined-urls@2?dts'

    In browsers with Skypack:

    <script type="module">
      import remarkLintNoDuplicateDefinedUrls from 'https://cdn.skypack.dev/remark-lint-no-duplicate-defined-urls@2?min'
    </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 remarkLintNoDuplicateDefinedUrls from 'remark-lint-no-duplicate-defined-urls'
    
    main()
    
    async function main() {
      const file = await remark()
        .use(remarkLint)
        .use(remarkLintNoDuplicateDefinedUrls)
        .process(await read('example.md'))
    
      console.error(reporter(file))
    }

    On the CLI:

    remark --use remark-lint --use remark-lint-no-duplicate-defined-urls example.md

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

     …
     "remarkConfig": {
       "plugins": [
         …
         "remark-lint",
    +    "remark-lint-no-duplicate-defined-urls",
         …
       ]
     }
     …

    API

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

    unified().use(remarkLintNoDuplicateDefinedUrls[, 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

    It’s likely a mistake when the same URL is defined with different identifiers.

    Examples

    ok.md
    In
    [alpha]: alpha.com
    [bravo]: bravo.com
    Out

    No messages.

    not-ok.md
    In
    [alpha]: alpha.com
    [bravo]: alpha.com
    Out
    2:1-2:19: Do not use different definitions with the same URL (1:1)
    

    Compatibility

    Projects maintained by the unified collective are compatible with all maintained versions of Node.js. As of now, that is Node.js 12.20+, 14.14+, and 16.0+. Our projects sometimes work with older versions, but this is not guaranteed.
