I am new to Antlr and my setup is as follows: Windows 7, Java JDK 1.7.0_17, AntlrWorks 1.5, Antlr 3.5.
The AntlrWorks Help-About shows the following information:
ANTLRWorks 1.5
ANTLR 3.5
StringTemplate v3 3.2.1
StringTemplate v4 4.0.7-SNAPSHOT
Java 1.7.0_17 (Oracle Corporation)
Chapter 3 of the Definitive Antlr Reference book introduces a sample grammar for expression evaluation (Expr.g), which I downloaded from the hyperlink in the PDF version of the book.
The book recomends using AntlrWorks and I am, however when I Generate Code (Ctrl+Shift+G) in AntlrWorks it produces code without the "throws" clause.
For example, the following is generated in AntlrWorks:
// $ANTLR start "prog"
// C:\\Users\\Mark\\Documents\\output\\Expr.g:12:1: prog : ( stat )+ ;
public final void prog() throws {
try {
Note the missing code after the throws keyword...
If I generate from the command prompt using this command line:
java -cp antlr-3.5-complete.jar org.antlr.Tool Expr.g
I get this output:
// $ANTLR start "prog"
// Expr.g:12:1: prog : ( stat )+ ;
public final void prog() throws RecognitionException {
try {
My question is this - how do I get AntlrWorks to generate the same code?
This is a known issue in ANTLRWorks 1.5 which has been resolved for the next release.
#5: ANTLRworks fails to generate proper Java Code

Running Stanford CoreNLP 3.4.1, plus the Spanish models. I have a directory of approximately 100 Spanish raw text documents, UTF-8 encoded. For each one, I execute the following commandline:
java -cp stanford-corenlp-3.4.1.jar:stanford-spanish-corenlp-2014-08-26-models.jar:xom.jar:joda-time.jar:jollyday.jar:ejml-0.23.jar -Xmx2g edu.stanford.nlp.pipeline.StanfordCoreNLP -props <propsfile> -file <txtfile>
The props file looks like this:
annotators = tokenize, ssplit, pos
tokenize.language = es
pos.model = edu/stanford/nlp/models/pos-tagger/spanish/spanish-distsim.tagger
For almost every file, I get the following error:
Exception in thread "main" java.lang.RuntimeException: Error annotating :

Any ideas? I haven't even begun to track this down. I'm certain the problem is in POS; tokenize and ssplit run just fine.
P.S. Please don't say "Upgrade to 3.5.0"; I don't currently have Java 8 installed and don't want to install it yet.
Thanks in advance.
Yes, it seems like there's a bug in the 3.4.1 Spanish models.
The Spanish 3.5.0 models actually seem to be compatible with Java 7. You can download the models used in 3.5 (stanford-spanish-corenlp-2014-10-23-models.jar) and put that on your classpath instead. This fixed the problem for me running Java 7 locally.
I am in a HUGE depression now! I spend 2 days trying to use boost.python . PLEASE guide me! I will explain what I did.
I have Winows 7 64 bit.
The Python is 64 bit 2.7.3 installed at C:\Python27_amd64.
Now, I take boost_1_54_0.zip and unzip in F: directory.
The I use cmd.
bootstrap
this creates project-config.jam. I edit it and insert
using msvc : 9.0 ;
using python : 2.7 : C:\Python27_amd64\python : C:\Python27_amd64\include : C:\Python27_amd64\libs ;
Now i do
.\b2
This process runs for 20 something minutes and I am told that boost has successfully been build.
After that I install boost binaries from http://sourceforge.net/projects/boost/files/boost-binaries/
The binaries get installed in C:\local\boost_1_54_0.
Now I want to create a General project.
Now, I use the code given for embedding python in C++ here
#include <boost/python.hpp>
#include <boost/detail/lightweight_test.hpp>
#include <iostream>
namespace py = boost::python;
using namespace std;
int main()
{
// Initialize the interpreter
Py_Initialize();
py::object main_module = py::import("__main__");
py::object main_namespace = main_module.attr("__dict__");
py::exec("print 'Hello, world'", main_namespace);
py::exec("print 'Hello, world'[3:5]", main_namespace);
py::exec("print '.'.join(['1','2','3'])", main_namespace);
}
I setup the header files and library in VC++ directories to F:\boost_1_54_0\boost_1_54_0 and F:\boost_1_54_0\boost_1_54_0\stage\lib respectively.
I also setup project-->properties-->configuration properties-->C/C++-->General-->Additional Include directories to C:\Python27_amd64\include
Likewise, I also setup project-->properties-->configuration properties--> Linker--> General to C:\Python27_amd64\libs;"C:\local\boost_1_54_0\lib64-msvc-9.0" .
Now when I compile using x64 debugger. It gives me an error
Unhandled exception at 0x00000000 in test8.exe: 0xC0000005: Access violation at location 0x0000000000000000.
I am struck since last 2 days...but thats the closest I have been since then. please help me!
So you mean a runtime error, right?
I think you should first ensure, that there is no exception thrown by boost::python itself.
First try to set the try block around you python calls with a catch(...)
If exception is caught it is most probably the boost::python::error_already_set exception.
So, you then should decode it like here
My java project updated to jdk 1.7.25, over Solaris 10 environment, this is the first time seen that there is a new warning message in build log: Anonymous sequences and array are deprecated (build IDL)
problem: The main GUI(build by jdk 1.7.25) cannot been brought up
We think this maybe a problem(but not sure). The idl file is very simple:
$ cat UnsubscribeAttb.idl
//../../../proj/request/requestIfc/UnsubscribeAttb.idl
include ../../../proj/request/requestIfc/subscribeKey.idl
module requestIfc {
struct requestIfc {
bool subscribeKeys;
sequence<subscribeKey> UnsubscribeAttbList;
}
}
I put in "typedef" at the front of the last line, but build immediately gives an error complained this line, but didnot give me a specific reason. Looking for your help.
Thanks,
Curtis

You have misconfigured your JRE in Eclipse. It'll work if you run it outside eclipse or fix your Eclipse JRE settings.
Hi I have a test project with Gallio 3.2 b.435 within VisualStudio 2010. Every time I launch any test the output windows pops out.
this is the error message
[error] An exception was thrown while exploring tests.
Location: C:\xxxxxxx(73)
Details: System.FormatException: Input string was not in a correct format.
at System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal)
this is the code at the line specified
71: [Test, ExpectedException(typeof(RulesException<Story>))]
72: public void CanNotSaveItemIfInvalid()
73: {
74: var story= new Story{ Id = 100, Tilte= "test" };
75: repository.Save(story, new MembershipUser());
76: }
This error isthrown no metter what test is under testing (the project contains 700 test)
Of course ;) the test compiles and passes and I cannot understand the error.
bye Stefano
This error is a known issue. It's due to a bug in the early version of Mono.Cecil (v0.6) that was used by the Gallio core engine. It has been fixed recently: Gallio is now using Mono.Cecil v0.9.
Please try out the latest version of Gallio (v3.2.2)
