lexer-generator

The regex-centric, fast lexical analyzer generator for C++ with full Unicode support. Faster than Flex. Accepts Flex specifications. Generates reusable source code that is easy to understand. Introduces indent/dedent anchors, lazy quantifiers, functions for lex/syntax error reporting and more. Seamlessly integrates with Bison and other parsers.
