Release history

See the changelog.

Token objects

Lexer tokens are represented as Token objects that implement the following interface:

interface Token {
  type: string;
  value: string;
  match: array | undefined;
}

Token properties

• type {string} - A string representing the token variant type. This property is necessary for classifying one or more characters so that parsers or compilers can determine what to do with the token.
• value {string} - The substring (or lexeme) that was captured for the token.
• match {array|undefined} - If a regular expression was used to capture a substring, the RegExp.exec() or String.match() arguments array can be stored on the token.

Source location

Add the source location (start, end, index and range) information to tokens using either of the following plugins (depending on preference for property naming conventions):

• snapdragon-position
• snapdragon-location
