HI to all.,
Eg:
// in Parser
tokenStream returns [String result = ""]
:
(id:RET_ID) {result = id.getText();} // RET_ID see in Lexer below
;
/* Q: here if i add (id:ID)+ to return more values.
Then I'm getting unexpected result */
// in Parser
LEX_ID
:
(ID)+ // ID is an identifier
;
RET_ID
:
(Whitespace)+ (LEX_ID)
;
Here in the parser I used to get only value of the token.
For eg: /* beginining comes some "Whitespace" */
HERE IS A TEST
The result : parser gets only one token ID (= HERE) and
leaving other after a whitespace
Coments : The Whitespace rule in the LEX_ID is must
for my construct so i cannot delete it.
Please give me some tips to solve the problem ..
Thanks.,
PREM
