unified-message-control

Enable, disable, and ignore messages with unified.

Install

This package is ESM only: Node 12+ is needed to use it and it must be imported instead of required.

npm:

npm install unified-message-control

Use

Say we have the following file, example.md:

<!--foo ignore-->

## Heading

And our script, example.js, looks as follows:

import {toVFile} from 'to-vfile'
import {reporter} from 'vfile-reporter'
import {remark} from 'remark'
import {messageControl} from 'unified-message-control'
import {commentMarker} from 'mdast-comment-marker'

remark()
  .use(warn)
  .use(messageControl, {name: 'foo', marker: commentMarker, test: 'html'})
  .process(toVFile.readSync('example.md'), function (err, file) {
    console.error(reporter(err || file))
  })

function warn() {
  return function (tree, file) {
    file.message('Whoops!', tree.children[1], 'foo:thing')
  }
}

Now, running node example yields:

example.md: no issues found

API

This package exports the following identifiers: messageControl. There is no default export.

unified().use(messageControl, options)

Let comment markers control messages from certain sources.

options

options.name

Name of markers that can control the message sources (string).

For example, {name: 'alpha'} controls alpha markers:

<!--alpha ignore-->

options.test

Test for possible markers (Function, string, Object, or Array.<Test>). See unist-util-is.

options.marker

Parse a possible marker to a comment marker object (Function). If the possible marker actually isn’t a marker, should return null.

options.known

List of allowed ruleIds (Array.<string>, optional). When given, a warning is shown when someone tries to control an unknown rule.

For example, {name: 'alpha', known: ['bravo']} results in a warning if charlie is configured:

<!--alpha ignore charlie-->

options.reset

Whether to treat all messages as turned off initially (boolean, default: false).

options.enable

List of ruleIds to initially turn on if reset: true (Array.<string>, optional). By default (reset: false), all rules are turned on.

options.disable

List of ruleIds to turn on if reset: false (Array.<string>, optional).

options.sources

Sources that can be controlled with name markers (string or Array.<string>, default: options.name)

Markers

disable

The disable keyword turns off all messages of the given rule identifiers. When without identifiers, all messages are turned off.

For example, to turn off certain messages:

<!--lint disable list-item-bullet-indent strong-marker-->

*   **foo**

A paragraph, and now another list.

  * __bar__

enable

The enable keyword turns on all messages of the given rule identifiers. When without identifiers, all messages are turned on.

For example, to enable certain messages:

<!--lint enable strong-marker-->

**foo** and __bar__.

ignore

The ignore keyword turns off all messages of the given ruleIds occurring in the following node. When without ruleIds, all messages are ignored.

After the end of the following node, messages are turned on again.

For example, to turn off certain messages for the next node:

<!--lint ignore list-item-bullet-indent strong-marker-->

*   **foo**
    * __bar__
