Hi, I'm an Antlr rookie.
I installed the IntelliJ Community Edition, hoping to get a good IDE for
my Antlr projects ...

The Antlr plugin fails to launch ... apparently it throws a
NumberFormatException on parsing the IntelliJ IDEA's ve
Hi Tommy,
Tree Grammars and ASTs are not competing in the same space. AST is just the
tree of nodes that represent your input. Tree Grammar is a grammar made
specifically to parse those ASTs.
You usually use them to walk through an AST you already built, and do things
with it. Think about the mu
Hi folks,
I have a small issue with multiple variables of a statement.
when i have one variable(ID) like the antlr grammar is
statement: 'select' ID {print $ID.text}
this is working fine.
when i have multiple variables how to represent in grammar and how can
i pass it as arguments to that pri
Hello,
I am building a test language with antlr.
Now I want to develop a code editor for this language with Eclipse RCP (as an
Eclipse Plugin) with code completion, colour for keywords,...
Have you do that from grammar or from java generated code?
Have you a simple example of language editor buil

somebody give me, for example "a: 'hello'; ", just that single symbol

StringTemplate to output "hi" from it. I can't find such a simple example
anywhere. i.
Sorry if I sound rushed, I'm doing so many other things as well.

I sounded rude! You are all legends, I just didn't want to delve into the
C/Java bytecode yet, just in order to learn the basic syntax. It's the basic
syntax is all I need right now, hence my request for an example translator
of "hi" -> "hello", and I can't find it "bunched together" as such.

We're setting up a new machine (I have my development machine running
Antlrworks-1.2.3) and can't find the Antlr3.Runtime.dll file in the
Antlrworks-1.3 download. Can somebody please point me to where it is
now? We need it for referencing from a Visual Studio project.
Thanks.

Have you tried looking on the Downloads page for ANTLR and downloading the .Net

I'm working with a tree parser that is creating ASTs of a custom type. This
CommonTree subclass contains a member named elementType that identifies the
type represented by the tree. How do I set the elementType dynamically within
an action?
I tried in the following way:
id:
^(AST_ID tok+=I

I have a dumbie question regarding where can I find examples of how
to build an antlr program using different IDEs?
Background: I am not a java programmer.
I have read part of the antlr book by Terrence Parr.
I think I have gotten as far as the Chapter that use STL to build

Hi friends,
Any ideas for my question?
Is there any solution for it or not ?
My Idea is to do action immediately.
So Can I have that facility in a grammar file like i can represent

Take a look at antlr.org and download antlrworks
Antlrworks can generate the the java files form the grammar files.

You can probably do:
id : ( ^(AST_ID tok+=ID+) -> ^(AST_ID whatever) { action } ;
Or get your method to return the node object and use it to rewrite the tree.

Hi,
on trying to implement control flow , in an AST walker grammar
