Validate invalid rule name in .textlintrc

[azu]

@textlint/config-loader is the only one that treat tetlintrc.

We can improve validation on loading textlintrc.

✅ Detect invalid rule name

• Already Done

It is just loading error.
textlint try to load invalid-rule module, but it doest not exists.

{
  "rules": {
    "invalid-rule": true
  }
}

Detect invalid child rule name of preset

• PR: ...

This case preset-abc does not have invalid-rule.
Currently, It will be just ignored, but we can validate it.

{
  "rules": {
    "preset-abc": {
      "a": true,
      "b": false,
      "invalid-rule": { "key": true }
    }
  }
}

📝 We can not validate rule option values
It needs to get option schema #700

Dynamic JSON Schema

Create JSON Schema dynamically.

• Example:
  • Angular: "$schema": "./node_modules/@angular/cli/lib/config/schema.json",

{
  "$schema": "./node_modules/textlint/schema.json",
  "rules": {
    "preset-abc": {
      "a": true,
      "b": false,
      "invalid-rule": { "key": true }
    }
  }
}

However, It is not useful at current. Blocker: #700

We can start static JSON Schema.

{
  "$schema": "https://textlint.github.io/schema.json",
  "rules": {
    "preset-abc": {
      "a": true,
      "b": false,
      "invalid-rule": { "key": true }
    }
  }
}
