Hi all,
I have the following grammar file:
//========================================
grammar k;
options {
output=AST;
}
rule : KEYWORD1 (KEYWORD2 enc=Name)? ';' ;
KEYWORD1 : 'keyword1';
KEYWORD2 : 'keyword2';
Name : Letter* ;
fragment Letter : 'a'..'z' | 'A'..'Z' ;
S : ('\t' | ' ' | '\n' | '\r')+ { $channel = HIDDEN; } ;
//========================================
The following text is not a valid one.
INPUT:
=====
keyword1 keyword2 keyword1 ;
OUTPUT:
=======
line 1:18 mismatched input 'keyword1' expecting Name
<mismatched token: [...@4,18:25='keyword1',<4>,1:18], resync=keyword1 keyword2
keyword1 ;>
How can I make a parser to recognize this input? I want to be able to allow
the keywords in the places where any char combination is allowed. How can I
make this?
Regards,
Gabriel
