Can grammar syntax alone accomplish this? Or, am I going to have to rely on
some additional code of my own such as actions? gated predicates? other?
1. A command, COMMAND, can be followed by three modifiers, M1, M2 and M3.
2. Each modifier has its own cardinality:
M1?
M2*
M3+
3.
What determines the value of the "s" argument to a DFA routine such as this?
protected internal int DFA21_SpecialStateTransition(DFA dfa, int s, IIntStream
_input)
The DFA is called via this in the parser:
alt21 = dfa21.Predict(input);
then, goes through some ANTLR call frames before emerging
I'm parsing a 7-bit ASCII stream ... 2 questions
Question 1: can't I just fall-thru wrt to lexer rules, where lexer rules are
specific-to-general, and avoid indeterminisms at run-time?
For example:
NULL: '\u'
;
SOH: '\u0001'
;
... // (EACH CONTROL CHARCTER HAS ITS OWN LEXER RUL
thanks.
org.antlr.Tool is happy with these two, regardless of which one is
above/below the other.
But, won't the DFA's care about the order???
DQUOTE : '"' ;
DQUOTE_STRING : DQUOTE ( ~('"') )* DQUOTE

Hi,
does anybody know how to determine the source of an error such as this?
the wiki says convert the grammar to v3; it is a v3 grammar.
Thanks.

I recently obtained antlr.3.1.3.jar, changed my CLASSPATH accordingly, and now
all my grammars have weird warnings and/or errors.
Is there more to an ANTLR upgrade than just downloading the new jar and making

I saw something close to my problem on the wiki,
http://www.antlr.org/pipermail/antlr-interest/2006-June/016563.html
But, I've got an "extra rule", filter. Must I resort to an action, or is there
a way to do this purely in the grammar file?
filter : // identifier, but *not* a keyword
