¶

Literal nodes are for plain strings in the regular expression. They are rendered as labels with the value of the literal quoted.
```
import _ from 'lodash';

export default {
  type: 'literal',
```

Renders the literal into the currently set container.

  _render() {
    return this.renderLabel([this.literal])
      .then(label => {
        let spans = label.selectAll('tspan');

        label.select('rect').attr({
          rx: 3,
          ry: 3
        });

        return label;
      });
  },

¶

Merges this literal with another. Literals come back as single characters during parsing, and must be post-processed into multi-character literals for rendering. This processing is done in Match.
```
  merge(other) {
    this.literal += other.literal;
  },

  setup() {
```

Value of the literal.

    this.literal = this.properties.literal.textValue;

Ordinal value of the literal for use in CharsetRange.

    this.ordinal = this.literal.charCodeAt(0);
  }
};
