Configuring Rules

Use the local .bpmnlintrc file to configure active lint rules.

Checkout the bpmnlint documentation for more information regarding this file.

Creating Rules

This project ships with a bpmnlint extension with the custom namespace. Add or edit rules in the extension's rules directory. Activate the rules via the local .bpmnlintrc file, in order to use them, prefixed with the namespace:

{
 "extends": [
    "bpmnlint:recommended",
    "plugin:custom/recommended"
 ],
 "rules": {
   "custom/no-manual-task": "warn",
   "custom/your-other-rule": "error"
 }
}

Plug-in Discovery

The custom namespace used by the shipped bpmnlint extension is arbitrary, i.e. can be changed freely. However you'd need to take into account how the linting infrastructure discovers rules and configuration:

  • It searches the rule provider library in the NodeJS search path (usually node_modules folder)
    • For a library bpmnlint-plugin-{custom}, given a namespace {custom}
    • For a library {@prefix}/bpmnlint-plugin-{custom}, given a scoped namespace {@prefix}/{custom}
  • Within a rule provider library
    • It searches the rules folder for a file matching an activated rule name
    • It searches the config folder for a file matching a configured configuration or inspect the plug-ins default export

In the case of our custom plug-in custom/recommended reference the custom configuration, exported by our plug-ins entry point. The rule custom/no-manual-task on the other hand references plug-ins entry point.

Development

# initial setup
npm install

# rebuild in development mode
npm run dev

# build the plug-in

To integrate with the Camunda Desktop Modeler move or link this plug-in into a folder under resources/plugins within the Modeler's plug-in search path. Reload the modeler to recognize plug-in changes.
