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 table cells are padded consistently. Tables are a GFM feature enabled with remark-gfm
.
Presets
This rule is included in the following presets:
Preset | Setting |
---|---|
remark-preset-lint-consistent | 'consistent' |
remark-preset-lint-markdown-style-guide | 'padded' |
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-cell-padding
In Deno with esm.sh
:
import remarkLintTableCellPadding from 'https://esm.sh/remark-lint-table-cell-padding@4'
In browsers with esm.sh
:
<script type="module">
import remarkLintTableCellPadding from 'https://esm.sh/remark-lint-table-cell-padding@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 remarkLintTableCellPadding from 'remark-lint-table-cell-padding'
main()
async function main() {
const file = await remark()
.use(remarkLint)
.use(remarkLintTableCellPadding)
.process(await read('example.md'))
console.error(reporter(file))
}
On the CLI:
remark --use remark-lint --use remark-lint-table-cell-padding example.md
On the CLI in a config file (here a package.json
):
…
"remarkConfig": {
"plugins": [
…
"remark-lint",
+ "remark-lint-table-cell-padding",
…
]
}
…
API
This package exports no identifiers. The default export is remarkLintTableCellPadding
.
unified().use(remarkLintTableCellPadding[, 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).
The following options (default: 'consistent'
) are accepted:
'padded'
— prefer at least one space between pipes and content'compact'
— prefer zero spaces between pipes and content'consistent'
— detect the first used style and warn when further tables differ
Recommendation
It’s recommended to use at least one space between pipes and content for legibility of the markup ('padded'
).
Fix
remark-gfm
formats all table cells as padded by default. Pass tableCellPadding: false
to use a more compact style.
