It seems that free projects name are often animals, especially the programming language ones: Python, Camel, Bonobo, etc.
And I wanted to have a recursive acronym with the word "Basic" in it. So, Gambas Almost Means BASic!
No, and it will never be!
Fortunately, there are many similarities, but do not expect to take your old Visual Basic code and run it on Gambas without any change.
You can go the troubleshooting page to find some examples of the differences between the two languages.

Never, I'm afraid. There are many reasons, good and bad:
In the future, I hope there will be a simple answer: "yes!". :)
Right now, there are reports of people compiling Gambas under BSD and Win32/Cygwin.
(It is impossible now to mix both programs as KBasic has become proprietary software.)
I think there are too many technical differences between the KBasic project and mine to merge the two projects.
KBasic seems to be based on KDE, and KDE only. My own interpreter does not depend on any toolkit or graphical environment. The Gambas interpreter is a text only program. The graphical part comes with components.
At the moment, there is only one graphical component, the Qt one. But, in the future, I plan to write a Gtk+ component, so that programs will be able to equally use Qt or Gtk+, or any other toolkit that has its own component.
Moreover, the development environment (the tool you use to write Gambas programs) is written in Gambas. The KBasic development environment seems to be written in C++, not in KBasic. It is a huge design difference.
So, that was the reasons why I think we could not easily merge... It is life!
It's pretty much the same as with KBasic (I think)
The problem is that the Gambas interpreter is very tight to the features of the language I needed.
Parrot features are very different from the Gambas ones. It is not just a matter of interpreting bytecode : there is the reference counting against garbage collector problem. What will happen to the components management system ? To the class inheritance management ? To the interpreter hooks ? And so on...
Porting the Gambas interpreter to Parrot, if a good thing, which is not evident, is a huge task anymay. It won't be done before years!
Short version:
tar xzvf gambas-x.xx.tar.gz cd gambas-x.xx ./configure # or ./configure --disable-db-component make make install
See also the long version.
If you have installed Gambas using the packaging mechanism of your operating system, it should be easy to use the normal uninstallation procedure.
If you have installed from source as root , just remove the installation directory. For example, if you have installed Gambas under /opt/gambas
, which is the default, just do, as root :
$ rm -rf /opt/gambas
YES ! You can currently access PostgreSQL and MySQL databases, and there is a SQlite driver in beta version. If you want to develop a driver for another database system, tell me. You are welcome!
You are welcome to help!
First you can subscribe to the developer mailing-list and introduce yourself.
Then, you must try to understand the Gambas architecture: the compiler, the interpreter, the development environment, the components, and how they live together.
Then, you can read the developer documentation on the Wiki: it will explain you how to program components.
You will find component example named gb.example
that is full of comments. By reading the source of this example, you will understand how to write a component.
If you want to write a database driver for the database component, the PostgreSQL driver is commented, so that you can more easily know how to do that.
Of course, I will answer any question and help you as much as I can, provided that you have spent more than a school year to learn C/C++ :-)
Any help on the following tasks is welcome. No C/C++ programming skill is required!
Yes, you can. But if you use the QT GUI component, i.e. if your program is graphical, then you must purchase a QT licence. Otherwise, make your software free as in freedom :-)
I won't, but I will help any people trying to do that.
I already compiled Gambas sources under Cygwin in the past, but didn't really succeed.
Note that there is a lot of things to port: process management, Qt component, and so on... This is a huge job.
