Codelyzer: component-selector rule does not work as expected

[marbug]

Hello.

I tried this with node v8.11.4 and v.10.9.0 and Angular6

Steps to reproduce are the following:

• Create project

      ng new marbug-app
  

• Go to project folder

      cd marbug-app
  

• Generate home module

      ng g module home
  

• Generate home component

      ng g component home
  

• Change prefix in marbug-app/angular.json from app to marbug:

        "root": "",
        "sourceRoot": "src",
        "projectType": "application",
  -     "prefix": "app",
  +     "prefix": "marbug",
        "schematics": {},
        "architect": {
          "build": {
  

• Change component selector prefix in marbug-app/src/app/home/home.component.ts file from app to marbug:

          @Component({
  -         selector: 'app-home',
  +         selector: 'marbug-home',
            templateUrl: './home.component.html',
            styleUrls: ['./home.component.css']
          })
  

• Add component-selector rule to marbug-app/tslint.json

       "no-output-rename": true,
       "use-life-cycle-interface": true,
       "use-pipe-transform-interface": true,
  +    "component-selector": [true, "element", "marbug", "kebab-case"],
       "component-class-suffix": true,
       "directive-class-suffix": true
     }
  

• Run

  npm run lint
  

• See error

  ERROR: /Users/marbug/cpp/angular/test-lint/marbug-app/src/app/home/home.component.ts[4, 13]: The selector of the component "HomeComponent" should have prefix "app" (https://angular.io/styleguide#style-02-07)
  
  Lint errors found in the listed files.
  

• Expected behavior: there is no such error

Thanks for the detailed description. We'll take a look at this in the next few days.

the root of the issue: the additional marbug-app/src/tslint.json file has been automatically generated, which also has component-selector rule by default, and it redefines component-selector rule from marbug-app/tslint.json by default prefix. Sorry for disturbing. Closing the issue...

No worries.
