Hi,
I build the following grammar with antlrworks:
grammar questionmark;
horef

antlrworks tells me check grammar succeeded. However, debugging does not

My question: how does the rule have to look like so that

Ah, hold on, you're using the `..` (range) operator inside a parser rule
(horef). Either create a lexer rule matching '?' 'a'..'z':

Hi,
I am new at ANTLR and I am having a problem trying to use the C# code
generated with the Kuka KRL Grammar...
I am using antlrworks version 1.4.3 , Visual Studio 2010.
While compiling the C# code, Visual Studio claims that it doesn't recognize
the getText() that appears like this:
Hi,
I'm trying to build a language to language translator using ANTLR. I'm also
using the Language Implementation Patterns book to find my way through this
task.
For building my symbol tables I would like to use some parts of the source
code that accompanies this book.
Could anybody clarify

I've gotten a lexer, parser (that outputs AST) and a tree parser work.
Currently the tree parser contain little code snippets that include
System.out.println to print my translated file.
Not very pretty, but it works.
My next step was to switch to StringTemplates, because I thought it
would
Hi Morgan,
Well, I'm a newbie too, but I can tell you how I understand and use
StringTemplates. For me, the end result of walking a tree that produces
StringTemplates is a StringTemplate which contains elements which are
themselves StringTemplates (or lists of String Templates), which contains
Andy, that does help... thanks for replying.
as I read about StringTemplates today I gathered they were capable of
much more than I had initially realized...
I'll go back and try to track down some examples of the nested String
Templates you spoke of.
Maybe I'll luck out and someone will point me
It's very confusing trying to read the detailed documentation on the
StringTemplate site until you get the basic idea, but keep at it. A key thing
for me was realizing that the objects embedded as parameters in a string
template can be just about anything that can be rendered to a string, or

Thank you for your feedback, and I have update now...

You should not be seeing more than a few newPool calls, however, if you
are building a tree then this may be affecting it. The reuse stuff was not
built for trees, so you may have to debug this because I won't have time
to look at new use cases for some time.
I will take out the myriad

You mean

no, I do not build. Work ANTLR itself to build AST

Hi -
This should be a very simple thing - I'm attempting to have my grammar hide
newline, carriage returns, etc. However, every concievable form of a
grammar that attempts to skip over these things or send them to the hidden
channel seems to fail for me. Here's a very basic example:

I just pasted your grammer into ANTLRWorks and it seemed happy. In the
interpreter I entered the following:
a
b
With a real newline between them, it gave the
