eslint-doc-generator

Generates the following documentation:

• README rules table
• Rule doc titles and notices

Also performs some basic section consistency checks on rule docs (will eventually be configurable):

• Contains an ## Options section and mentions each named option (for rules with options)

Setup

Install it:

npm run --save-dev eslint-doc-generator

Add it as as script in package.json (included as a lint script to demonstrate how we can ensure it passes and is up-to-date on CI):

{
  "scripts": {
    "lint": "npm-run-all \"lint:*\"",
    "lint:docs": "markdownlint \"**/*.md\"",
    "lint:eslint-docs": "npm-run-all update:docs && git diff --exit-code",
    "lint:js": "eslint .",
    "update:eslint-docs": "eslint-doc-generator"
  }
}

Add the rule list marker comments in your README.md rules section:

<!-- begin rules list -->
<!-- end rules list -->

A new title and notices will be automatically added to the top of each rule doc (along with a marker comment if it doesn't exist yet). You may need to manually remove old notices.

Usage

npm run update:eslint-docs

# Disallow use of `foo` (`no-foo`)
