import { Font } from './font';
import { TabNote, TabNoteStruct } from './tabnote';
import { Category } from './typeguard';

export class GraceTabNote extends TabNote {
  static get CATEGORY(): string {
    return Category.GraceTabNote;
  }

  constructor(noteStruct: TabNoteStruct) {
    super(noteStruct, false);

    this.render_options = {
      ...this.render_options,
      // vertical shift from stave line
      y_shift: 0.3,
      // grace glyph scale
      scale: 0.6,
      // grace tablature font
      font: `7.5pt ${Font.SANS_SERIF}`,
    };
