Lexer

class Lexer extends AnyRef

A simple lexer for tokens as they are used in JSON, plus parens (, ) Tokens understood are:

(, ), [, ], {, }, :, ,, true, false, null, strings (syntax as in JSON), integer numbers (syntax as in JSON: -?(0|\d+) floating point numbers (syntax as in JSON: -?(0|\d+)(\.\d+)?((e|E)(+|-)?\d+)?) The end of input is represented as its own token, EOF. Lexers can keep one token lookahead
