[antlr-interest] I: Compile errors with CSharp2 Target

[Massimiliano Donini]

Hi simon
don'you miss Language=CSharp2 in grammar's option section?
And why in grammar there is package definition? (line 98 and line 104) But
the erroneous code is defined above (line  107)

private boolean allowShortOpenTag = false;

    // Handle the first token, which will always be a BodyString.
    public Token nextToken(){
        //The following code was pulled out from super.nextToken()
        if (input.index() == 0) {
            try {
                state.token = null;
                state.channel = Token.DEFAULT_CHANNEL;
                state.tokenStartCharIndex = input.index();
                state.tokenStartCharPositionInLine =
input.getCharPositionInLine();
                state.tokenStartLine = input.getLine();
                state.text = null;
                state.backtracking = 0;
                mBodyStringRest();
                state.type = BodyString;
                emit();
                return state.token;
            } catch (NoViableAltException nva) {
                reportError(nva);
                recover(nva); // throw out current char and try again
            } catch (RecognitionException re) {
                reportError(re);
                // match() routine has already called recover()
            }    
        }
        return super.nextToken();
    }

    /**
     * Property to enable short open tags
     * 
     * Returns true if short open tags are enabled
     * false if short open tags are disabled.
     * 
     */
    public boolean isAllowShortOpenTag(){
        return allowShortOpenTag;
    }

    /**
     * Property to enable short open tags.
     *
     * Set to true to enable short open tags and false 
     * to disable.
     */
    public void setAllowShortOpenTag(boolean val){
        allowShortOpenTag = val;
    }

All these methods are written in target language (default Java) So you have
to change it for compile with C# For example Boolean should be bool and
Token should be IToken, input.index() should be input.Index and so on.

Hope it helps
Best regards
Max

Hi Max,

Thanks for the thoughts - I've attached the generated code.   You can
see the grammar here:

Cheers,

Simon
