The generated AST has the expected left associativity. https://github.com/neogeny/TatSu http://tatsu.readthedocs.io/en/stable/ v4.2.5 -------- * #42 Rename vim files from grako.vim to tatsu.vim (@fcoelho ) * #51 Fix inconsistent code generation for whitespace (@fpom ) * #54 Only care about case of first letter of rule name for determining advance over whitespace (@acw1251 ) v4.2.4 --------- * #40 Make the start rule default to the first rule defined in the grammar (@hariedo) * #43 Import re from tatsu.util to support optional regex-only features (@azazel75) * #47 Fix incorrect sample code in documentation v4.2.3 -------- * #37 Regression: The #include pragma works by using the EBNFBuffer from grammars.py.
