[il-antlr-interest: 32657] [antlr-interest] New Guy Question...
Hi everyone,
Just dipping my toes in the ANTLR waters do to speak.. In other words, I am
definitely new at this, so a couple quick questions.
1) Is this list/email address the best way to ask questions?
2) Any idea when The Definitive ANTLR book will be updated? It
appears to be based on 3.0, whereas the ANTLR product is 3.3. I still
purchased the book, and it is helping tremendously.
3) My language of choice is Delphi. Does anyone have a sample grammar
and the Delphi equiv of Test.java that they could send me.? (George at woh
dot rr dot com)
4) How do I handle case insensitivity? For example, assume in the
following grammar that the token 'CALL' can be all caps, all lower letters,
or a mix. How do I recognize it?
grammar T;
/** Match things like call foo; */
CALL : 'CALL';
ID : ('a'..'z'|'A'..'Z')+ ;
INT : '0'..'9'+ ;
NEWLINE:'\r'? '\n' ;
WS : (' '|'\t')+ { $channel=HIDDEN; } ;
MULT: '*';
ASSIGN: '=';
PLUS:'+';
MINUS:'-';
r : CALL ID ';' {System.out.println(invoke +$ID.text);} ;
Thanks,
George Spears

[il-antlr-interest: 32658] Re: [antlr-interest] New Guy Question...
Hi George,
I can properly answer most of your questions, as for the tougher/trickier
one I will
1) AFAIK, yes.
2) I think Terence has been working on it.
3) AFAIK, there is just a Pascal grammar. However, you'd better wait for the
veterans' reply.
4) I would solve this like that:
call : C A L L
;
fragment C : ('c' | 'C');
fragment A : ('a' | 'A');
fragment L : ('l' | 'L');
I don't know if it is the best approach though.
Best regards,
Vinicius Durelli

You have to handle case insensitivity the hard way: fragment A :'A' | 'a'; fragment B :'B' | 'b'; fragment C :'C' | 'c'; fragment D :'D' | 'd'; fragment E :'E' | 'e'; fragment F :'F' | 'f'; fragment G :'G' | 'g'; fragment H :'H' | 'h'; fragment I :'I' | 'i'; fragment J :'J' | 'j'; fragment K :'K' | 'k'; fragment L :'L' | 'l'; fragment M :'M' | 'm'; fragment N :'N' | 'n'; fragment O :'O' | 'o'; fragment P :'P' | 'p'; fragment Q :'Q' | 'q'; fragment R :'R' | 'r'; fragment S :'S' | 's'; fragment T :'T' | 't'; fragment U :'U' | 'u'; fragment V :'V' | 'v'; fragment W :'W' | 'w'; fragment X :'X' | 'x'; fragment Y :'Y' | 'y'; fragment Z :'Z' | 'z'; ADD : A D D; ALLOCATE : A L L O C A T E; ALL : A L L; On Sun, Jun 5, 2011 at 4:30 PM, Udo Weik weikeng...@aol.com wrote: Hello George, Just dipping my toes in the ANTLR waters do to speak..

At the moment, I'm still busy to get all my development tools working, so I can't help you with that ANTLR problem. What I have done so far: - Tried to get the C target language working with C++Builder - Problems with missing Object-files. That's an typical C++Builder-issue. I installed now Visual C++ 2010 Express, but no progress at the moment because my focus moved to Eclipse temporarily. - Eclipse - installed - ANTLR-plug in installed - Python-plug in PyDev installed When you look in the ANTLR interest archives (yep, I looked for an search option, too) you will find some questions related to C++Builder and Delphi from me. But until now no echo out of the universe. Pls. send me a PM, so we can discuss our further cooperation.

You have to handle case insensitivity the hard way: fragment A :'A' | 'a'; [...] I don't think it's a necessity to do it this way. Actually, I think it would be better using a specialized input stream that does any necessary transformation. Your mileage may vary ;) Cheers, Marco List: http://www.antlr.org/mailman/listinfo/antlr-interest Unsubscribe: http://www.antlr.org/mailman/options/antlr-interest/your-email-address -- You received this message because you are subscribed to the Google Groups il-antlr-interest group.

[il-antlr-interest: 32665] [antlr-interest] advices about phrase generation
hi all, just wondering... about the org.antlr.tool.RandomPhrase source... can someone help me to adapt it to generate a JMenu ? it should be something like the image in syntax diagram window from antlrworks.. but navegable by menus, so I can select a decision/path to follow, instead of the random one used in that example. cheers, Mauricio Chicalski List: http://www.antlr.org/mailman/listinfo/antlr-interest Unsubscribe: http://www.antlr.org/mailman/options/antlr-interest/your-email-address -- You received this message because you are subscribed to the Google Groups il-antlr-interest group.

[il-antlr-interest: 32666] Re: [antlr-interest] Error in the method specialStateTransition(int, IntStream)
Hi Jim,
Thanks for the solution..
But I am facing one problem.
If I say
expr: SET VALUE ( i = Int { setValue($i.getText());} |
v = SPL_CHARS+ {
displayErrorMessage($v.getText());})
;
SPL_CHARS : ('\U' .. '\U')+;
When I give some non numeric input and call the method
displayErrorMessage($v.getText()) , I get a null pointer exception. It says
that v is null.
What should I do?
I need to capture this value and display the error message..
PS: It is not a simple grammar for SET command. In our product, we are
migrating from manual parsing to ANTLR Parser. So I don't think it is an
over kill :)

The '+' in this means match everything and keep matching everything. You
cannot use + here, you need:
SPL_CHARS : .;
Then use SPL_CHARS+ in your grammar not (.)+
Though I think you would be better writing a small piece of code to
process this really; ANTLR is a bit overkill for set x y

Subject: [antlr-interest] Error in the method
specialStateTransition(int, IntStream)
Hi,
I need to develop a grammar with the following structure:
set Param-Name Param-Val
The grammar which I have developed is working fine except for one
Problem:
- If the Param-Val does not match the constraints defined for certain
Param_Name, then I need to throw an error.
I am doing it like this:
command:SET ARRAYSIZE ( Int {/*Process the arraysize*/}
| (.)+ {/*Display eror message*/})
;
Int:('0'..'9')+;
Char:('a'..'z');
SPL_CHARS : ('\U' .. '\U')+;
The problem is that I am getting an error: The code of method
specialStateTransition(int, IntStream) is exceeding the 65535 bytes
limit
What should I do?
PS: The grammar which I have to write is pretty big.. If I make
SPL_CHARS
: ('\U' .. '\U') then its working fine Please suggest some
solution..
Thanks
