ANTLR v4.5.3 Release Notes

Release Date: 2016-03-31 // about 8 years ago

  • 🔋 Features / improvements

    • 🆕 New grammar option: contextSuperClass. All parse tree internal nodes will derive from this. Default is ParserRuleContext. Should derive from ultimately RuleContext at minimum.
      Java target can use contextSuperClass=org.antlr.v4.runtime.RuleContextWithAltNum for convenience. It adds a backing field for altNumber, the alt matched for the associated rule node.
    • Added getMaxTokenType() to Vocabulary interface
