Hi,
I'm facing the task to build a language to language translator that should
translate the programming language PEARL to C++. The idea is to build a
combined grammar to build an AST and then output the C++ code using a tree
grammar with StringTemplate.
At a first glance I picked the Python t
Thanks to all responders.
I'll try to use Java as a target language and see how far I get.
BTW. PEARL as input language wasn't a typo. PEARL is an acronym for
Process and Experiment Automation Realtime Language and quite different from
PERL.

I've built a

Hi,
I'm having a similar rule in my tree grammar that is simply collecting the
output of other rules into a common StringTemplate. Therefore I think your
rule is correct so far. (The "problem" template is in a *.stg file.)

Hi,
the gUnitEditor seems to be a nice tool but it doesn't handle *.gunit files
with an included "@header {package my.pack.there;}" gracefully.
It is able to read such a file but when writing the "@header" line is
discarded. I unpacked the antlr-3.4-complete.jar and patched the
StringTemplate
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
Hi, i have some problem in generated java code form one rule like this:

Hi,
I created a grammar with the latest antlrworks. With antlrworks' debug
functionality I "tested" the grammar. For proper throughout testing I
copied the generated Lexer and Parser code to my eclipse project. The
only change I made to the code was to add a package declaration.
However, when

"ctree.type|0||". When I use simply "15" as input, I get the -
correct - output "ctree.type|7|INT|".
Thanks,

Hi,
from what I read in the mailing list and in the wiki error handling and
recovery is complex. Is there an easy way to disable recovery? Maybe
another flag in the options{} part of a grammar? Or a method called on
the Lexer/Parser to set the recovery mode?
I am looking for the least invasive

I build the following grammar with antlrworks:

Hello,
I started working on another JUnit testing framework for ANTLR.
Mainly as a mechanism to learn how to write a JUnit testing and,
secondarily, to test my grammars in a way that I was comfortable with.
It's a great mix of Jeremy D. Frens' assert code from
y samples that

I was reading about the following grammar on page 287 of the PDF document
grammar t;
s : X r A B

r : A

I don't see where the problem is since the alternatives in s begin with two
different tokens X and Y. I think that since these two tokens are different I
can easily con
Ahh, the DFA for the 'r' rule. That makes sense now. Interesting example.

I'm still seeing you run maven 3 instead of maven 2. The current POMs will not
build under maven 3 and deleting ~/.m2/repository will not help things.

I got some free time to tinker around with an old project of mine
https://github.com/maguro/lua4j
so I updated the version to 3.4 of ANTLR and am now unable to compile it. The
parser that gets generated is not valid Java code even though ANTLR does not
print out any error or warning messages.
