I am getting a NoViableAltException in the ANTLR . But I want to get
the full string from the place where it occurs . For example:
The input is :
create antlr antlrname=antlr1 antlrype=type1
where the lexer definition is as follows:
CREATE:"create ";
ANTLR:"antlr";
ANTLRNAME:"antlrn"('a' ('m' ('e')?)?)?;
ANTLRTYPE:"antlrt"('y' ('p'('e')?)?)?;
In the above example since it was not able to identify the
token "antlrype=type1" it throws NoViableAltException with the LT(1)
as "antlr". But I need to display the whole string "antlrype=type1 "
as invalid.
My question is : How to get the string (antlrype=type1 )from the
place where the NoViableAltException occurs??
Thanks in advance
