Hello,
I have to confess I am an absolute noob regarding ANTLR. I try to use
it to parse a type of LTL formula (later it will probably complete
SystemC) and include this into an Eclipse Editor. So, finally I will
want to use the parser, lexer and tree walker to recognize syntax
errors, do the outlining and so on.
My problem is that I cannot catch the "No viable alternative at
character" exception.
My grammar is:
expr : SCA_COMMAND '("' inner* '");';
inner : XFG(inner_quantor)+;
inner_quantor
: '['( INT | (INT':'INT))']';
SCA_COMMAND
: 'sca_check' | 'sca_monitor';
INT : '0'..'9'+ ;
XFG : ('X' | 'F' | 'G' );
NEWLINE:'\r'? '\n' ;
WS : (' '|'\t'|'\n'|'\r')+ {skip();} ;
When I try to parse >sca_check("hello"); I get console output, but the
exception is not thrown. When I try to parse >h, for example, I get an
exception.
Basically, I just need a way to get a list of all errors in the
syntax, with lines and colums, so I can use that information in the
error marking of Eclipse.
Any ideas?
Thanks a lot.
