I'm using the new ANTLR3 maven plugin described at
http://www.antlr.org/antlr3-maven-plugin/
. Thanks to Jim Idle!
The new plugin has a minor "feature" that the older plugin also had.
If I edit my grammar and do "mvn package", maven doesn't detect that
the grammar has changed. Maven says
What about chunking your input using some basic thing like a
StringTokenizer, then parse each paragraph separately?
Be aware that Wiki grammar is not a simple thing to parse.

Hi,
Here is the Exceptions log and Stack Trace:
Exception in thread "Thread-7" java.lang.OutOfMemoryError: Java heap space

I'm still struggling to get this working.
For example, a Wikipedia "title" looks like this:
STARTOFLINE == title text == WHITESPACE? EOL
There are a bunch of other control characters ('*', '<', etc...) as well that
can go into a title string. I need to be able to parse this:

You might want to double-check CL, unless that

Hi,
I have a language that can embed code snippet. For example the language can

The idea is to treat everything inside the Invo

It is not a good idea to use backtracking though unless your input is

I have a parser generating an AST. Now I would like to walk that AST

Dear all,
we are using ANTLR3 (ver. 3.1.3) to generate a Java parser using C target.
The generated code is supposed to be compiled with Visual Studio 2008, and
later used in a VC++ project.
The grammar file that we used is Java 1.5 grammar for ANTLR v3 written by
Terence Parr. We found it in

OK, doing this seems to have fixed it. The other weird thing is that the
first compile after a pull seems to work - while the rest fails. Even
when doing clean inbetween. Ve

Start AW from the command prompt and press Crtl-Break (or Ctrl-C) in the
command prompt window once AW has frozen.

It's also worth noting that in many languages this isn't considered to
be strange. You just evaluate the assignment operator right-to-left; the

Hi,
I would like to change the token names for error display.
I used have this:
value : simpleValue | '{' property '}';
where a token type for the curly braces was created by ANTLR (T_XXX),
but if it was missing then in the error message a '{' was generated
because for that token in the Java t
Take a look at 'filter' mode of ANTLR lexer. This will let you skip text
you are not interested in.
Posting a more specific example of what you need might help.

How about something like this?
r:(ID EQ)+ INTLIT SEMICOLON -> ^(ASSIGN ID INTLIT)+
;
So, for your example, this will create two subtrees with ASSIGN as root.
The tree generated will be ^(nil ^(ASSIGN Odd 0) ^(ASSIGN Even 0))
And then you can write string template in the tree walker
