- Differences with Rexical
- Additions or Changes
- A generic rake rule is defined for rex files.
- All regular expressions must be slash delimited.
- Regular expressions now use ruby interpolation.
- Macros define class constants.
- Rules can be activated by predicate methods.
- Rule actions are only a single-line.
- Rules can invoke methods.
- Rules can define state.
- Use a ‘start` section to define pre-lex code.
- Rule state can be inclusive or exclusive.
- Default ‘do_parse` will dispatch to lex_xxx automatically.
- ‘text` is passed in, or use `match` or `matches`
- You can override the scanner class by defining ‘scanner_class`.
- Removals
- There is no command-line tool.
- There are only two options: debug and stub.
- Probably others…
