Hi,
There is something fundamental and important that I have not understood with
ANTLR grammars.
If I need to parse something like...
int test;
strig another;
int variable;
string here;
You notice there is a typing error on the second line ('strig' instead of
'string').
How do I make a grammar that will not stop parsing but, continues after an
error??
Below is an example how I CANNOT make it work the right way (created AST
contains only 'int test ;')..
grammar List;
options {
language = CSharp3;
TokenLabelType = CommonToken;
output=AST;
ASTLabelType = CommonTree;
}
@lexer::namespace{ConsoleApplication4}
@parser::namespace{ConsoleApplication4}
public r
: variables*
;
variables
: type ID ';'
;
type
: 'int'
| 'string'
;
ID : 'a'..'z' + ;
WS : (' ' |'\n' |'\r' ) {$channel=Hidden;} ;
Many thanks for your time and help,
Mari
