C++ Extension to Java template converter

I realized that the majority of the time taken on converting most extensions to java is spent on implementing the jump tables and creating the functions and getting the parameters.

This program takes your C++ MMF2 extension source code folder and generates a template Java file automatically. It does the following for you:

• Creates constants for each condition/action/expression
• Implements getNumberOfConditions()
• Implements the 'action','condition' and 'expression' functions.
• Generates functions for all your conditions, actions and expressions with the same names as in you C++ source code.
• Gets the parameters automatically for you

Here is an example on how it works:
Example main.cpp (simplified for your sake) :D
Generated Java template from the main.cpp file

Here is the program:

ExtensionToJava.exe (Requires .NET 3.5 runtime. You should already have it)
Source code (Visual Studio Project)

EDIT: It now also parses rSDK.

Wonderful! That will help a lot developers to convert their extensions! :D

Please do! :)

I updated it to also parse the rSDK now. I had no other test-projects than the rSDK template to work with, so please test it on your own rSDK extensions :)

cool!

I tried it with many rSDK extensions and all of them return unhandled exceptions. :(

This is what it gave me (German...):

Code:

Can you send me your main.cpp file? (maybe just a stripped version of it without the implementation code)
Thanks :)

I tracked down the problem. Just add some lines of code before the first CONDITION().

Example:

PHP Code:

---

// ============================================================================
//
// This file contains the actions, conditions and expressions your object uses
// 
// ============================================================================

#include "common.h"

int foobar() {      //
    return 100; // This part will cause the exception
}                   //

// ============================================================================
//
// CONDITIONS
// 
// ============================================================================

CONDITION(
    /* ID */            0,
    /* Name */            "%o: %0 == %1",
    /* Flags */            EVFLAGS_ALWAYS|EVFLAGS_NOTABLE,
    /* Params */        (2,PARAM_NUMBER,"First number",PARAM_NUMBER,"Second number")
) {
    int p1=Param(TYPE_INT);
    int p2=Param(TYPE_INT);
    
    return p1==p2;
}

Ah sorry, slight mistake in the parsing grammar. Will fix it soon :)

Try it again, I fixed the crash + another bug. :-)

Indeed! Worked fine with OpenGL. This is really useful. Thanks. :)

Awesome, Andos. You have helped me infinitely with my conversions! :)

I plan to redo the parser for the original SDK since it isn't very reliable. If you have any comments or anything on the lines it will break.

However.. Do you think I should release it to the public now? Some people (not in this forum) probably have some extensions they want to port to Java at some point soon.

Certainly - if there are any remaining bugs they'll probably be uncovered more quickly by the public than they would here.

Anders, found a bug (at least with rSDK) - it converts string parameters to getParamString when it's actually getParamExpString.

It also converted

char * Delimiters=(char *)Param(TYPE_STRING);

To

String param1 = act.getParamXdelimiters(rh,1);

Andos - any chance you could fix this? It'd make converting Lacewing a hell of a lot easier (many, many ACES!)

Updated it to version 1.01. Please tell me if you have any problems with it :)

That's excellent news. :)
