Hi folks, When feeding ANTLR 3.4 with my Java grammars it doesn't generate valid Java sources (26 compiler errors) - with v3.3 everything is okay.
Here's a snipped of the grammar that raises one of the problems: statement : block | assertStatement | ifStatement | forStatement | [... and so on ...] ; ifStatement : IF parenthesizedExpression ifStat=statement ( ELSE elseStat=statement -> ^(IF parenthesizedExpression $ifStat $elseStat) | -> ^(IF parenthesizedExpression $ifStat) ) ; Amongst other things v3.4 generates the following code for the 'ELSE' branch of the rule 'ifStatement' (have a look at the local 'variable declaration': void =null;): public final void synpred137_Java_fragment() throws RecognitionException { void =null; // [... some comments not relevant here ...] { match(input,ELSE,FOLLOW_ELSE_in_synpred137_Java9244); if (state.failed) return ; pushFollow(FOLLOW_statement_in_synpred137_Java9248); elseStat=statement(); state._fsp--; if (state.failed) return ; } } However, v3.3 generates the following code from the same grammar: public final void synpred137_Java_fragment() throws RecognitionException { JavaParser.statement_return elseStat = null; // [... some comments not relevant here ...] { match(input,ELSE,FOLLOW_ELSE_in_synpred137_Java9244); if (state.failed) return ; pushFollow(FOLLOW_statement_in_synpred137_Java9248); elseStat=statement(); state._fsp--; if (state.failed) return ; } } The complete grammars can be found at ... http://www.habelitz.com/index.php?option=com_content&task=view&id=12&Itemid=8 Any hints? A bug within v3.4?
