Grako Compatibility¶
竜 TatSu is routinely tested over major projects developed with Grako. The backwards-compatibility suite includes (at least) translators for COBOL, Java, and (Oracle) SQL.
Grako grammars and projects can be used with 竜 TatSu, with these caveats:
- The Python module name changed to
tatsu
. ignorecase
no longer applies to regular expressions in grammars. Use(?i)
in the pattern to enablere.IGNORECASE
- Left recursion is enabled by default because it works and has zero impact on non-recursive grammars.
- Deprecated grammar syntax is no longer documented. It’s best not to use it, as it will be removed in a future version of 竜 TatSu.
