Usage
You probably want to use it on the CLI through a config file:
...
"remarkConfig": {
"plugins": [
...
"lint",
+ "lint-no-duplicate-definitions",
...
]
}
...
Or use it on the CLI directly
remark -u lint -u lint-no-duplicate-definitions 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-no-duplicate-definitions'))
.process('_Emphasis_ and **importance**', function (err, file) {
console.error(report(err || file));
});
