remark-lint-fenced-code-flag

Check fenced code block flags.

Options: Array.<string> or Object, optional.

Providing an array is as passing {flags: Array}.

The object can have an array of 'flags' which are allowed: other flags will not be allowed. An allowEmpty field (boolean, default: false) can be set to allow code blocks without language flags.

Use

You probably want to use it on the CLI through a config file:

 …
 "remarkConfig": {
   "plugins": [
     …
     "lint",
+    "lint-fenced-code-flag",
     …
   ]
 }
 …

Or use it on the CLI directly

remark -u lint -u lint-fenced-code-flag readme.md

Or use this on the API:

 var remark = require('remark')
 var report = require('vfile-reporter')

 remark()
   .use(require('remark-lint'))
+  .use(require('remark-lint-fenced-code-flag'))
   .process('_Emphasis_ and **importance**', function (err, file) {
     console.error(report(err || file))
   })
