Time to bring C# to netbeans?

Hey man,

I'm working on a plugin to implement C# into netbeans: https://github.com/Chris2011/CSharp-for-netbeans

Do you want to help me with this or do you have time? First I read a lot of tutorials to implement a new language into netbeans. I read about ANTLR that I need a grammar file and with this file, the ANTLR api (In netbeans) creates a lot of other files, that I need. Lexer, token files? Don't know. Maybe I don't need it because you already created it. I don't know atm.

First thing that I tried is ANTLRWorks2: http://tunnelvisionlabs.com/products/demo/antlrworks. It's an application created as a netbeans standalone application, to have syntax highlighting for .g files and generator. When I tried to open your file and hit the action "Generate Recognizer..." I got the error: This command is not valid in legacy (ANTLR 3) mode. But I don't know which. Possible that the syntax, which you need, is available in ANTLR 4 first and not in 3? Whatever I created a bug: tunnelvisionlabs/antlrworks2#55

So let me know, if the project sounds great for you to help or not.

Cheers

Chris

Parser fails to recognize comparison expressions

I tried to use your project to build a syntax tree, but your CSharp4.java parser is not configured to do so. I used csParser.java directly and it seems to fail recognizing comparison expressions. It seems to be a problem in the grammar definition, that causes the parser to try to match a generic construction when it finds something like f = i < 1.
The error is: line 7:11 no viable alternative at input '1'

namespace ConsoleApplication1 { 
    public class TestFileTwo { 
        public void foo ( ) { 
            f = i <mismatched token: [@53,108:108='1',<36>,7:11], resync=< 1> ; 
        } 
    } 
}

Exception while running csMain.java

I used AntlrPluginIDE in eclipse to compile .g files.
All done without error.
I then ran csMain and I got the following error :

Exception in thread "main" java.lang.NullPointerException
    at lang.csharp.CSharp4PreProcessor.mTokens(CSharp4PreProcessor.java:2698)
    at lang.csharp.CSharp4PreProcessorImpl.mTokens(CSharp4PreProcessorImpl.java:44)

Then source code line is :

gUnicode.mTokens(); if (state.failed) return ;

in CSharp4PreProcessor.java function :

public void mTokens() throws RecognitionException {
        // C:\\Users\\olivier\\workspace\\CSharpGrammar-master\\grammars\\CSharp4PreProcessor.g:1:8: ( Pp_directive | Unicode. Tokens | CSharp4Lexer. Tokens )
        int alt64=3;
        alt64 = dfa64.predict(input);
        switch (alt64) {
            case 1 :
                // C:\\Users\\olivier\\workspace\\CSharpGrammar-master\\grammars\\CSharp4PreProcessor.g:1:10: Pp_directive
                {
                mPp_directive(); if (state.failed) return ;


                }
                break;
            case 2 :
                // C:\\Users\\olivier\\workspace\\CSharpGrammar-master\\grammars\\CSharp4PreProcessor.g:1:23: Unicode. Tokens
                {
                gUnicode.mTokens(); if (state.failed) return ;


                }
                break;
            case 3 :
                // C:\\Users\\olivier\\workspace\\CSharpGrammar-master\\grammars\\CSharp4PreProcessor.g:1:38: CSharp4Lexer. Tokens
                {
                gCSharp4Lexer.mTokens(); if (state.failed) return ;


                }
                break;

        }

    }
