import remarkLint from 'remark-lint'
import remarkLintNoTableIndentation from 'remark-lint-no-table-indentation'
import remarkParse from 'remark-parse'
import remarkStringify from 'remark-stringify'
import {read} from 'to-vfile'
import {unified} from 'unified'
import {reporter} from 'vfile-reporter'

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

await unified()

.use(remarkLintNoTableIndentation)
.use(remarkStringify)
.process(file)

console.error(reporter(file))

`

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

API

This package exports no identifiers.
It exports no additional [TypeScript][typescript] types.

$3

Warn when GFM tables are indented.

###### Parameters

There are no options.

###### Returns

Transform ([Transformer from unified][github-unified-transformer]).

Recommendation

There is no specific handling of indented tables (or anything else) in
markdown.
So it’s recommended to not indent tables and to turn this rule on.

Fix

[remark-stringify][github-remark-stringify] with
[remark-gfm][github-remark-gfm] formats all tables without indent.

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-table-indentation@5,
compatible with Node.js 16.
