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 tables have initial and final delimiters. Tables are a GFM feature enabled with remark-gfm.

Presets

This rule is included in the following presets:

Preset	Setting
remark-preset-lint-markdown-style-guide

Install

This package is ESM only. In Node.js (version 12.20+, 14.14+, or 16.0+), install with npm:

npm install remark-lint-table-pipes

In Deno with esm.sh:

import remarkLintTablePipes from 'https://esm.sh/remark-lint-table-pipes@4'

In browsers with esm.sh:

<script type="module">
  import remarkLintTablePipes from 'https://esm.sh/remark-lint-table-pipes@4?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 remarkLintTablePipes from 'remark-lint-table-pipes'

main()

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

  console.error(reporter(file))
}

On the CLI:

remark --use remark-lint --use remark-lint-table-pipes example.md

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

 …
 "remarkConfig": {
   "plugins": [
     …
     "remark-lint",
+    "remark-lint-table-pipes",
     …
   ]
 }
 …

API

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

unified().use(remarkLintTablePipes[, 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

While tables don’t require initial or final delimiters (pipes before the first and after the last cells in a row), it arguably does look weird.

Fix

remark-gfm formats all tables with initial and final delimiters.
