Title:
Combined grammar importing lexer and parser grammar could not define
lexer rules
Description:
A combined grammar with imported lexer and parser grammar is given. In
this grammar
header rules have to be set for example for package declarations.
Software:
antlrworks-1.3.1.jar
--------
lexer grammar lex;
LETTER : 'a'..'z' ;
SPACE : ' ' ;
--------
parser grammar par;
letter : LETTER ;
spaces : SPACE+ ;
--------
grammar gram;
import lex, par;
@parser::header{
package grammar;
}
@lexer::header{
package grammar;
}
letters : letter+ ;
stuff : ( letters spaces )+ ;
--------
This grammar cannot be generated because of following error:
Cannot generate the grammar because:
error (143): par.g:10:15: unknown or invalid action scope for parser
grammar: lexer
note: If the combined grammar only imports the lexer grammar, all will
be fine.
