Latest Alpha Release (Available on Web Site)

[Charles Pegge]

This release features wide-string support for Unicode, among a number of other changes.

If you have any precompiled DLLs and EXE files which are Oxygen-dependent they will need to be recompiled to work with this release of Oxygen.dll.

Yes that was quite an intensive round

Here is a quick demo of the wide string / unicode support
It relies on the greek typeface being supported by the Operating Sytem.

[kryton9]

Thanks Charles will grab the new version now.

Alpha 30

Another hunk of updates.

The main feature is the OOPification of operarators. The older syntax has gone. All operations are now methods. There is a simple example for 3d vectors in:
examples/OOP/Operators/


This version also includes a simple GDIplus example demonstrating how to load JPEG/PNG images:
examples/GUI/WinImage.o2bas

Alpha 32

Two main features of this release:

Register names are no longer reserved and may be reused for variable names. For example: cr0 cr1. This is not recommended for global variables but it will make coding a little less restrictive. Frequently used variable names like sp or ax or dx can now be used provided they do not clash with inline asm code within the same sub or function.

The Opengl examples and their include files have been made case capital sensitive so that they can be used with C headers such as those from GDIplus.

Alpha 35

In this release I have concentrated on the internals and fixed a number of issues relating to Type interpretation and conversion.

One major difference you need to know about. Due to a number of logistical problems I have removed support for multidimensional arrays from the core language. It's not as bad as it sounds. Multidimensioning is now placed entirely in the hands of the programmer. I found that with the preference for using UDTs and Classes multidimensional arrays are not used so often. But more significantly I found developing generic code for processing matrices much simpler with a more flexible definition of dimensions. (Example to follow)

The most efficient way of creating your own is to use a macro:

Code: [Select]

#define rows 100
#define columns 100
dim as long ard[rows*columns]
#indexbase 0

#define arr(row,column) ard[row*columns+column]


Code: [Select]

Many changes in this version. The core keywords remain the same but gaps in functionality have been filled and the most important development is the extended auto-conversion between different types which considerably improves the behaviour of mixed string and numeric types. My apologies for turbulence during this period of development! And many thanks for creating new code, putting Oxygen through its paces.

Thank you Charles!

I bought an Android tablet today finally. I will tinker with the stock ROM and Android for a couple of days. Then I plan on rooting it and installing one of the recommended ROMS. I don't know if I can install WINE on a rooted Android device... but if I can, will let you know how Oxygen runs.

Hi Kent. What type of processor does your new tablet have? I think most of them are ARM and do not have any of the infrastructure associated with a PC. I believe all development has to be done through a Java based API.

Anyway I will be very interested to know about your exploration of this device.

I forgot WINE is not an emulator. So it won't work as you figured out. They did make some nice mod tools. It makes it relatively easy to try out different ROMS. I tried 2 so far. It is fun. The tegra 2 is pretty neat which is a Cortex A9 cpu with Nvidia graphics. I got lots to learn about these devices, luckily lots of help on the web.

I'm not sure if a ARM emitter is even on Charles to do list...

If it is... look at the tcc C compiler as it comes with 3
different emitters: x86, x64 and ARM.
(the newest one from the tcc repository)
