  +#### prettier-pug specific options
  +
  +These are specific options only for prettier-pug
  +They should be set via `Prettier`'s `overrides` option
  +
  +- `attributeSeparator`
  + Change when attributes are separated by commas in tags.
  +
  + Choices:
  +
  + - `'always'` -> Always separate attributes with commas.
  + Example: `button(type="submit", (click)="play()", disabled)`
  + - `'as-needed'` -> Only add commas between attributes where required.
  + Example: `button(type="submit", (click)="play()" disabled)`
  +
  +The definitions for these options can be found in [src/options.ts](https://github.com/prettier/plugin-pug/blob/master/src/options.ts)

  ## Integration with editors
  If you are using a text editor that supports Prettier integration (e.g. [Atom](https://atom.io/packages/prettier-atom)), you can have all Prettier perks for your Pug code too!
