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.

Title: Re: Latest Alpha Release (Available on Web Site)
Post by: Charles Pegge on July 12, 2011, 08:40:39 PM

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.

Charles

Title: Re: Latest Alpha Release (Available on Web Site)
Post by: kryton9 on July 12, 2011, 11:48:15 PM

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)

Post by: Charles Pegge on July 21, 2011, 08:53:32 AM

Hi efgee,

I'm hoping that by making self-compile my next priority, modularising the compiler internals in Oxygen will be easier than in FreeBasic. Adding new emitters and other enhancements should then proceed faster.

Charles

Title: Re: Latest Alpha Release (Available on Web Site)
Post by: Charles Pegge on July 21, 2011, 09:12:24 AM

I'm making a few changes directed towards self-compiling.

One is the cpu calling convention which passes parameters in the CPU registers instead of on the stack. This is primarily intended for internal use to get the maximum possible performance with simple procedures.

I have also corrected a potentially serious problem which showed up in one of the OOP examples. Thanks Maxim!

This was the example. I have changed the syntax slightly but the original should also perform correctly now.

examples/OOP/features/AttachObject.o2bas

Code: OxygenBasic

 
  /*

    end if
    return s
  end method

Are you saying that you can move to a self compile model in steps rather that going cold turkey with FreeBASIC?

Title: Re: Latest Alpha Release (Available on Web Site)
Post by: Charles Pegge on July 21, 2011, 02:43:13 PM

Most of the code will self-compile, but I want to get it as close to 100% as possible and it is easier to make these adjustments and test them on a working system.

Charles

Once you get to a self compile stage, will the O2 source look more Basic and less ASM?

Title: Re: Latest Alpha Release (Available on Web Site)
Post by: Charles Pegge on July 21, 2011, 09:33:55 PM

That's an interesting question John. Some kind of Assembler will always be needed in critical areas, even if it is an abstract assembler like Java ByteCode or Common Intermediate Language.

If Oxygen produced 100% efficient Assembler from Basic there would be no need but we are not at that stage yet :), and I feel some coding is actually clearer when expressed directly in Assembler rather than Basic notation, especially logic.

As I proceed with the self-compile project , I will post updates here whenever I need to change anything.

There was one problem using the RTL32.inc (Run time library for independent execution), making low level calls using a macro. This has now been fixed.

Missing right brackets with procedure calls now trigger a compile error. Thanks Peter!

I'm trying to get my arms around this self compile process. Are you saying that no other compiler tools (assembler/linker) will be needed to generate an executable? If that is the case, I should be able to use ScriptBasic to compile a O2 program.

Title: Re: Latest Alpha Release (Available on Web Site)
Post by: Charles Pegge on July 23, 2011, 07:52:54 PM

Hi John,

Oxygen can self compile because it has its own built-in assembler and linker. It requires no other utilities to create an executable image or binary file.

ScriptBasic could also be used to compile O2 or indeed ScriptBasic programs and produce binaries in the same way. But it would be quite slow because it is an interpreter.

Charles

Define slow?

I can live with SB taking a second to compile a program when a compiled version may do it in a 1/10 of the time. What I would gain using an interpretive environment for debugging and readability would far surpass any inconvenience from having to a blink once before having something to run. If there happened to be some function of the compiler that is CPU intensive, I could create a SB extension module (shared object) written in O2 or C.

Quote

Basic and Macros are converted to Assembly code.
Prologs, epilogs, PE headers and sections are added.
Assembly code is converted to Oxygen machine script.
Oxygen machine script is converted to binary and linked.
The executable binary image is then (optionally compacted into a PE file,
or executed directly in memory

o2Sema-->o2fini-->o2Assm-->o2Link-->(makeEXE/DLL)

If I were to use O2 as a framework for a SB compiler, I would compile the pcode SB generates to execute. No need to LEX, error check and is in the most efficient form to compile.

Title: Re: Latest Alpha Release (Available on Web Site)
Post by: Charles Pegge on July 24, 2011, 04:57:38 AM

Yes John, I agree 10x slower is tolerable, at least on programs up to 20000 lines.

The development time-scales are probably the biggest obstacle. It has taken about 10000 man-hours to develop Oxygen so far and I have a notional budget of 1000 hours for the self-compile stage alone. So be warned that anything to do with compiler making will take a large portion of lifespan :)

I am always looking for short cuts but so far, they elude me!

Post by: Charles Pegge on July 25, 2011, 01:32:20 PM

You are ahead of me guys! I have only just got it to produce a binary. There's much more to be done in the debugging and optimisation department. The time required, I estimate to be about 10 times longer than this stage.

The EXE is to facilitate early testing but I advise against trying to run it without safety helmet and goggles :o

Charles

PS:
One curiosity: The code is about 30% longer than the FB compile, yet compresses 30% smaller in a zip file. (114K). Presumably there are more repeating elements, favouring greater compression.

This fixes a bug with string constants:

This one has more efficient string parameter passing, and a number of minor corrections/adjustments. Most of these have been fed back from the Self-compile project.

Another feature I have reintroduced in this version, which I hope will assist modular programming.

You can hide most things inside a scope, then select the functions you want to be visible by tagging them as exposed.

Code: OxygenBasic

'Scoping and selectively Exposing functions in Oxygen
'====================================================
 
declare function f1()
declare function f2()
 
 
scope
  const string s="This is module1"
  function f1() exposed
    print s
  end function
end scope
 
 
scope
  const string s="This is module2"
  function f2() exposed
    print s
  end function
end scope
 
f1()
f2()

scope  
  single d=100,x,y,R=90,r,ß=45
  function Hypozykloide(single x1,y1,r) exposed  
    x=d*cos((1-R/r)*ß)+R-r*cos(ß)
    y=d*sin((1-R/r)*ß)+R-r*sin(ß)

Title: Re: Latest Alpha Release (Available on Web Site)
Post by: efgee on August 16, 2011, 07:01:00 PM

Would it not be better (syntax wise) to have:

exposed function f1() as long

otherwise if there is a return type it would be:

function f1() as long exposed

which somehow looks silly to me.

;)

Title: Re: Latest Alpha Release (Available on Web Site)
Post by: JRS on August 16, 2011, 09:24:49 PM

I see the SCOPE/END SCOPE as defining module status to that block of code. If you call a function in a SCOPE structure, variables access is restricted to those variables within that SCOPE structure.

If I'm wrong in my assumption, please enlighten me.

Title: Re: Latest Alpha Release (Available on Web Site)
Post by: Charles Pegge on August 16, 2011, 09:48:39 PM

Frank,

I take your point. Exposed has been assigned to the group of function tag words including at, link, external, export, com. I can improve the sense by allowing commas to be used between these words. What do you think?

function f1() as long, exposed

John,

Scope is a nesting construct. Everything defined above the scope is visible from the inside, but anything defined inside the scope is not normally visible to the outside. When the scope closes, all the symbols that were created within the scope are forgotten.

All functions and classes use this mechanism to isolate their static and local variables.

Charles

I believe this is a novel feature. Also the localisation of macros, the nestability of classes and functions, one inside the other, are not features found in Basic or C++.

Post by: kryton9 on August 19, 2011, 11:06:30 PM

Peter, Oxygen is just in Alpha and although we have found it quite usable I think that we need to give Charles time to get it to a release candidate. I have decided that I will work on my engine in c++ in the meantime and make my oxygen version later once I get a complete engine working and my classes all working cleanly. I put a lot of effort into learning c++, at least to a state where I am not afraid of it anymore, so I would like to make use of that study in completing my engine with it and then move into oxygen.

I think your skill set fits in with working with oxygen at this early level. You know assembly and winapi well and I think that works well with Charles and troubleshooting oxygen development. So your work is not wasted.

Title: Re: Latest Alpha Release (Available on Web Site)
Post by: Charles Pegge on August 20, 2011, 07:12:06 PM

Hi Kent,

Your work on Oxygen classes was very useful and I would like to explore the larger scale architecture a in little more depth. For instance I found my classes often become too large for comfort and wonder whether splitting down into smaller components would produce a better program design, with more reusable parts.

What classes are you working with in your C++ projects?
