Rules

Our documentation lists all currenty implemented rules, the ./rules folder contains each rules implementation.

Do you miss a rule that should be included? Propose a new rule.

Configuration

Create a .dmnlintrc file in your working directory and inherit from a common configuration using the extends block:

{
  "extends": "dmnlint:recommended"
}

Add or customize rules using the rules block:

{
  "extends": "dmnlint:recommended",
  "rules": {
    "label-required": "off"
  }
}

Visual Feedback (TODO)

Integrate the linter via dmn-js-dmnlint into dmn-js and get direct feedback during modeling.

To try out visual validation, checkout the dmnlint playground.

Writing / Consuming Custom Rules (TODO)

Use the dmnlint playground to implement new rules with quick visual feedback.

For more details on how to define and consume custom lint rules check out the dmnlint-plugin-example.
