object oriented basic

Matthias,

I'll send you an email explaining how the project manager
needs to behave. Anyone else who would like a copy should send
me an email at [email protected] and I'll send you one as well.

Stephane,

That sounds great, keep me updated. If you'd like some
more info on how it needs to interact with the preprocessor
and (eventually) the translator send me an email at the above
address and I'll let you know.

Hi,

I'm build and create an wingui ide like delphi
written in delphi 5.0

Hi David,

i´m interested to help programing the project manager.

What´s Your targets ???

I just got a web site (http://www.dvenable.com/bdk), but I
gotta warn you, it's in pretty bad shape right now. Alot of
the info is outdated as I've updated the preprocessor (among
other things) quite a bit since I last updated the website.
However, I plan to work on it pretty soon and get it a little
more up to speed.

I just read the article you mentioned. Very interesting. It addresses most of the issues I mentioned. It would be easiest to model it after C++'s method of OO, and then parse directly to C++, according to it. Interesting. Maybe it's still a pipe dream, but we'll see. I may have some interesting stuff for you, Dave, in the next few months (or years.. .

Is there a web site where I can read more about your preprocessor and things?

Hi all,

OOP is very use full in PB but not 100% OOP. I think build-in
more hybrid OOP with OOP programming and Structured programming to
Let stay the default concepts like DDT,SDK and adding only OOP but
not pure 100% OOP because that's then very deficult for learn
programming in OOP
The concept is thinking in objects and classes.

The Open-Source development model's merits can be debated, as can the willingness of others to contribute. As with many people, I'd like to contribute to such a project, but I don't have time to do this between work and school. In the coming months, perhaps.

Some issues to think about when designing your system
- multiple vs single inheritence
- strict private/public (purist view) vs private/protected/public (c++/java view)
- virtual methods
- pure OO (smalltalk, purist) or hybrid (c++/java and probably more practicle too)

Some of this is hard to implement in pure powerbasic. For instance, virtual methods can be implemented without help from the language through tables of function pointers in C, for example (see gtk+ which is completely object-oriented and written in straight C)

I recently read the article "Object Oriented Basic"
( http://www.powerbasic.com/files/pub/docs/OOBTXT.ZIP )
which essentially describes creating a frontend to
the PB compiler. This would translate the object oriented
basic code into error free PB code to be compiled by PB.
The article also does an excellent job at explaining oop,
and outlines an oo basic syntax.
I have recently been working on a project, which I
am calling the Basic Development Kit (bdk), which will
include a basic preprocessor, some useful functions, and
hopefully a project manager. BDK will be public domain in
its entirity and open source as well. I am about 90% done
with the preprocessor and a few other utilities, but I
haven't even begun on the project manager. After reading
the article, I figured why not implement an oo basic and
include it as well.
Obviously, this would be a huge task for one person
alone. Given how well the open source community has fared,
and how loyal PB programmers are to PB, I figured that it's
pretty likely that alot of people will want to help out.
Especially since this will be an improvement to both the
basic language and PB (and the fact that it'll be free).
As I said, I still have a little bit left on the
preprocessor so I plan to finish it up, release the
beta, and then dive into the object oriented basic.
Anyone who is willing to help out is welcome.

Thanks in advance,

Dave
