Hi comunity;
Would like to know how do u specify in a template the possible
repetition of some part of it.
for example in that the instelseif and cond_elseif could apper 0..n times:
instif(cond,instif,instelseif,cond_elseif,instesle) ::= <<
if(){
}
else if(){
}
else{
}>>
Many thx

Hi people;
In case you want to generate a NameX tree grammar; How to specify
NameX.tokens to AntlrWorks so it takes all the tokens defined in a
lexer.

Hi everybody;
Having this lexer rules, parsing the input doesn't recognize 'integer'
as a type, only recognize types vector of integer as a token like
integer[] or integet[][][].

CORCHE_ABRE: '[';

I think that altering code generation so catch-clauses get replace
with the action specified is the best aproach in my case:
@rulecatch {
catch (RecognitionException e) {

Divide and conquer, one thing is the fucionality of a syntax and

Hi,
Have look at this link:
http://www.temporal-wave.com/index.php?option=com_psrrun&view=psrrun&Itemid=56
ANTLR can build, a Tree graph for you, then you will have to add the
functionalities required to determine a control flow...
