Hello EveryOne, I have a problem while using generated parser\lexer from
following grammar. while using parser it is giving exception while freeing
parser.parser->free(parser);following is the prototype grammer file. Is
something wrong with grammar rule?(i am importing all lexer rules from
ExprLexerRules file) I am able to generate Lexer\Parser for
following grammar.Identifier used here is like ABD or BCG etc.
expression like ABC += BCDgrammar Expression;options {
backtrack = true; memoize
= true; k =
2; language = C;
output = AST;
ASTLabelType = pANTLR3_BASE_TREE; }//importing already
defined lexer and parser rulesimport ExprLexerRules
;operations :
binaryoperation? ;
binaryoperation : binaryexpression
EOF ; binaryexpression
: LPAREN! Identifier (DIVIDEEQUAL | PLUSEQUAL | MINUSEQUAL | TIMESEQUAL)^
Identifier RPAREN!
; DIVIDEEQUAL
: '/=';PLUSEQUAL
: '+=';MINUSEQUAL :
'-=';TIMESEQUAL : '*=';
