Well, the lexer counts newlines (or CR+LF pairs) so as to provide a line

Hi,
I really like the Doxygen HTML files on the ANTLR Web site. Once upon a

Is the Doxygen config file used to generate them available somewhere?

Hi,
Is there any reason the many *_return classes generated when a grammar
uses the "returns [ ... ]" construct (under Java) cannot be
declared "private" (or, at least, "protected")?
This would have the salutary effect of excluding them from the external

Hi,
I've just discovered that an ANTLR parser created using version 3.0 that
I'd been using successfully for over a year is broken now that I rebuilt
it using ANTLR 3.1.1.
The rules in question (hopefully this tiny excerpt is sufficient for
someone to recognize a change between 3.0 and 3.1) are:
Hi,
I recently had to write a parser for a language that, like Prolog,
allows definition of new operators and redefinition of the precedence,
arity and associativity of existing operators. (I did use ANTLR and was
forced to simply fix the default operator structure to that language's
defaults

I doesn't seem to work if I just press the "Parse to AST" button with

Hi,
Has anybody come up with good recipes for using the GraphViz
package's "dot" command for rendering the graphs of ASTs produced by
ANTLR 3 (.1.1)? If so, could you share? Or point me to resources that
would be me a head start on coming up with good incantations of the dot
command?
Thanks.
Hi,
I just discovered that in parser rules with both a rewrite clause _and_
an action block, the action block must _precede_ the rewrite clause or
the generated Java code is malformed and will not compile.
This is OK:

I'd like to return an array from a parser rule (in a tree grammar, if it

Unfortunately, the Java array declaration syntax, [], appears to be
interfering with ANT

If one is to parse an infix operator notation, exemplified by this

and produce from it this AST:

Hi,
I have a couple of productions that use a prefix operator that may be
repeated arbitrarily. One of them (negation) just has the operator
symbol. The other has a keyword (two different keywords, actually)
followed by an identifier.
For example, with the negation operator, this:
