Sounds pretty fun, I'll have a try.

Thank for contribution

Bugfix v0.34

Lower and upper case searching was errors in the translation.

Sorry :oops:

could you go a little more OOP for the parser? for instance I know why you are using the underscores, but... using a \ or a dot would make much more sense, really.

Even if you use :: as C++, it'll be much more solid.

May I ask, can you call encapsulated classes from public? or only privately?.

Just a few ideas: you could call "this" for yourself, ie as a reserved variable label and thus prevent from using the pointer all together, you can parse this one easily.

this->var = 10 ; var being a variable in the class

etc..

Another idea: don't pass *this by yourself, use the parser to add this pointer... thats the whole principle and idea of an oop parser, to do this stuff so you don't have to...

If you take my ideas it'll become a cleaner and more solid tool to work with

PS: as parser I mean preprocessor, etc...
PS2: baseclass? wtf?

mk-soft · **Posted:** Sat Jan 26, 2008 6:49 pm

the precomiler read only the code and bind a topfile and a bottomfile to the mainfile as includefile.
The syntax with *this as Pointer to encapsulated data and "\" as bind to structures and Interfaces come from PB
I won´t to translate all code, because it´s a big problem with includefiles und debuging code.

Quote:

All Attributes with Class allways privatly but you can definded all attributes as Public with a new pointer to object . That´s not right method.

Code:

*publicMaster.MasterClass = *User1
Debug "Public: " + *publicMaster\LastName

Sorry for my english.

I mean, what if I want to do this:

myfile\read\string()

Too bad about the "can't be arsed to make a proper preprocessor" part

I guess I'll have to continue mine after all... Both existent OOP tools are flawed in many points and the authors don't seem to care :cry:

- I appreciate the effort but it's not good enough IMO as to start porting code and use it on a regular basis... Since it's not full OOP by any means.

Please wait to translate to englisch sample

It´s the same method when you using DCOM-Object in PB

I know, I know... but again, the purpose of a preprocessor is to enable this sort of things

Thanks.

Is there REALLY any need for that? This isn't the first occasion you have gone out of your way to be as insultive as you possibly can towards somebody who is doing code in their spare time for free. Perhaps you SHOULD put your money where your big mouth is and bloody well write some code and realease it in the same manner so WE can all sit back and tear you to shreds for a change eh?

superadnim · **Joined:** Thu Jul 27, 2006 4:06 am **Posts:** 443

Or perhaps you could get laid and we could all sit back and laugh at you.
I said thanks, I said it was a good tool, I did add my constructive criticism if you don't like it, there you are. I also mentioned I'm working on my own preprocessor, but for people like you I would rather not share a bit. :wink:

Ahhhh, I really love cheap shots... especially as you keep turning me down for sex.. I guess you'll be waiting a while for the laughter to errupt

Information:

The PreCompiler produces additional program code and macros.
This is merged at the beginning and at the end of the Main file.
The syntax of purebasic uses all techniques for the programming of objects.
No source codes are changed or replaced. I do not have also before this
differently to reallisieren around the full to purebasic to keep kompalitaet.

To produce all objects in LinkedList over put on after the release by objects no memory leakages.
This is unfortunately often not considered with the use AllocateMemory and FreeMemory.

Purebasic is a procedurale programming language however object orientation supported.
I use this support for the PreCompiler.

For complete object-oriented programming there are Visual studio or C++.

Thanks, mk-soft

@superadnim

I agree with LuCiFeR[SD], mate. You can make the odd good point but you almost always deliver these things in an obnoxious way. Yours is destructive, not constructive criticism.

LuCiFeR[SD] makes an excellent point about the generous contributions to these forums.

Posts like yours make some people think twice about releasing things and so you spite yourself and the rest of us when you belittle other people's efforts.

You imply you have all this (usually unfinished) but awesome code lying around. In different areas of expertise. Mate, I think you're skiting. It is put up or shut up time - so let's see this OOP masterpiece of yours.

MK-Soft ... just don't care ...

If you dont agree with his " xyz must be available in an OOP paradigm" he just presumes that you got less skills and no idea how an oop language has to be. So be prepared ;-)

Its not the way of the C# approach you "would like to have" but IT IS OOP.
The authors maybe just don't want to follow your order giving style, your teasings and presumtions regarding skills.

And btw: You know, not everything is "flawed" or as you say monkey-style builded just cause you are the one who can't handle it.
