The Line Numbers plugin supports the display of line numbers for single line sources. This is disabled by default. It would be great to have a configuration option so that this can be configured from the app.module.

In v11, You can use the line numbers options as directive inputs

<pre>
  <code [highlightAuto]="code"
        lineNumbers
        singleLine
        startFrom="5"></code>
</pre>

Or globally

export const appConfig: ApplicationConfig = {
  providers: [
    provideHighlightOptions({
      fullLibraryLoader: () => import('highlight.js'),
      lineNumbersOptions: {
        singleLine: true,
        startFrom: 5
      }
    })
  ]
};
