    Class Attributes

    Attributes

    A performant bitset representation to handle SGR attributes.

    const attributes = new Attributes()
      .foregroundColor(BasicColor.Red)
      .underline()
      .bold()
      .italic();

    attributes.has(1 << Bit.Bold); // true
    attributes.has(1 << Bit.Italic); // true
    attributes.has(1 << Bit.Underline); // true
    attributes.has(1 << Bit.ForegroundColor); // true


    attributes.and(new Attributes().backgroundColor(BasicColor.Blue));
    attributes.or(new Attributes().backgroundColor(BasicColor.Blue));
    attributes.xor(new Attributes().backgroundColor(BasicColor.Blue));

    new Style(attributes);
