remark-lint-fenced-code-marker

Warn for violating fenced code markers.

Options: '`', '~', or 'consistent', default: 'consistent'.

'consistent' detects the first used fenced code marker style and warns when subsequent fenced code blocks use different styles.

Fix

remark-stringify formats fences using '`' (grave accent) by default. Pass fence: '~' to use ~ (tilde) instead.

See Using remark to fix your Markdown on how to automatically fix warnings for this rule.

Or use this on the API:

 import {remark} from 'remark'
 import {reporter} from 'vfile-reporter'
 import remarkLint from 'remark-lint'
 import remarkLintFencedCodeMarker from 'remark-lint-fenced-code-marker'

 remark()
   .use(remarkLint)
+  .use(remarkLintFencedCodeMarker)
   .process('_Emphasis_ and **importance**')
   .then((file) => {
     console.error(reporter(file))
   })
