LIT conversion (C#) developer

Jaapjan · 08-30-2005, 07:15 AM

Is there anyone out there who ever tried to port the CLit code to c# instead?

Just trying to meet up or talk a bit with other such developers who tried or thought about it (with reasonable expectations of having succes).

Shouldn't be too difficult if the original source is available (which I think it is).
But what for ?

Jaapjan · 08-30-2005, 08:38 AM

I see you haven't actually looked into it yet (at all?)

It would be fairly complex in fact. It is not a simple format.

Jaapjan, what's complex about it? The sources can be easily compiled with Microsoft Visual C and any other GNU C compiler. Shouldn't it be straightforward to transform C code into C# ?

Jaapjan · 08-30-2005, 09:21 AM

The trouble is that the code is not object oriented, scattered about through many files and using a great deal of macro's.

Accurately deducing what a the more complex parts do precisely is ... not easy.

I C. Thanks for the clarification

Jaapjan · 08-30-2005, 09:23 AM

It's not a problem to explain. Feel free to verify my statements. I love to hear you find it very easy, because I could ask all the tough questions to you then...

doctorow · 08-30-2005, 09:24 AM

Well I have never programmed in C#. But I did C++ and usually it was not an issue incorporating C code into C++.

Jaapjan · 08-30-2005, 09:32 AM

Yes, C and C++ aren't very different and you can intermingle said variants of the C language without any sort of worry. This is not the case with C# though, which is entirely object oriented.

In fact, c# doesn't even have support for pointers, nor macro's. It's not as much a thing of porting but of rewriting based on the original C code.

doctorow · 08-30-2005, 10:53 AM

May I ask you what you are working on? A project involving ConvertLit always sounds intriguing.

Jaapjan · 08-30-2005, 10:58 AM

Off course. A reader for the lit format for windows mobile 5. Particularly, the code should be in the .net compact 2 framework and entirely managed code, meaning it ought work wherever mono or microsoft .net is. Possibly that .gnu variant too, whatever it is called though I won't bother with that.

It's just a hobby thing but I made quite some progress.

Is it absolutely required to use only managed code? If not, why not compile the original CLit source as a DLL and call its functions using P/Invoke?

Jaapjan · 08-30-2005, 12:04 PM

I require it to be completely managed, yes. Besides that, I do not want to use any of the original code. I merely use it as a reference.

I take it then you don't want to release your reader as GPL?

Jaapjan · 08-30-2005, 12:18 PM

To be honest, I have no idea. Right now it is a hobby thing. 'See if I can do it' thing. To be honest, I don't think I would make any sort of commercial thing out of it. If that is your worry.
