Pekr: re "Cortex MCUs -  are those too low level MCUs, or is it just 
a matter of some work to do?"


Cortex-M raises two issues: first, these cores just support the Thumb 
instruction set (which Red/System does not support, at the moment). 
Second, most -M cores have no memory management unit (MMU).

Do they support the Thumb2 set (32-bit instructions)?

Depends on the core.

Cortex-M3 supports _only_ Thumb2, for example.

I can use -r for no-runtime :)

Yep, but you'll be quickly limited, unless you rewrite the runtime 
at least partially. ;-)

I am making some changes to the compiler debug logs output to avoid 
being pollute by runtime lib logs.

(Cortex-M0 supports Thumb plus a few Thumb-2 insns, IIRC.)

Oldes: I've pushed a change in master branch, you can now use -v 
5 to get the output of your own code only (with max details).

I agree with Gregg, great job. I tempted to pull out my Sharp Zaurus 
SL-6000 (xscale-based) just to see if I could get Red to compile 
on that but I had better return to my "work".  :-(

Oldes: about floating point support, I have made a short review of 
required changes in current compiler. I will publish it tomorrow, 
so we can decide on the priority with Kaj and others.

James: thanks!

I'm looking into the allocator. alloc-series says it takes a size 
in cells of 16 bytes, but then it relays it to alloc-series-buffer 
unmultiplied, which says it takes a size in bytes, and only rounds 
it up to 16 bytes

How are non-block series going to be allocated, for example binaries 
of one byte per cell?

Alloc-series: right, the comment is obsolete, it accepts any integer 
value as argument and leave it to alloc-series-buffer to round it 
to 16 bytes.

Non-block series: in fact all series will use the same allocator, 
so 128-bit (16 bytes) is the minimum allocating unit.

Is there any roadmap to know what comes next? E.g. when work on RED 
itself will begin, etc?

Red: it has already begun, the lexer has been implemented.

I will be back to Red compiler as soon as I finish debugging the 
ARM backend.

I might start also working on floating point support but we'll see 
that tomorrow.

For anyone interested, here's a direct link to the GTK+ example that 
shows all currently implemented widgets:

Thanks Kaj.

Here's a screenshot of Kaj's GTK-widgets under Win7: http://static.red-lang.org/red-system-gtk-widgets.png

Thanks :-)

I put alla files in red-system/tests, including Red-48x48.png. I 
got GTK-widgets.reds running, but with "Window: skipping missing 
icon.". Where do I put the PNG? As far as I see there is no path 
defined for this file in GTK-widgets.reds. Using Win7 (x64). I thought 
the icon would be built in the exe. I tried now to put the PNG in 
the same dir as the built exe and the icon shows, but I still got 
that DOS terminal to open. Sorry for stupid newbie questions.

For getting rid of the DOS console, you should compile using the 
following option: -t Windows

The default target on Windows for Red/System apps is MSDOS (console 
mode). When Red will be there, I guess we'll switch the default target 
to Windows (GUI mode).

The icon file should go in the directory where you start the executable 
from, so usually that would be the builds/ directory that Red creates 
within itself

Alternatively, you could add a path to the icon in the program

There are no facilities in Red yet to add resources within executable 
files

I think that reshacker tool should work for that: http://www.angusj.com/resourcehacker/

Yeah, but it's very system dependent

An executable resources handling module for Red/System linker would 
be nice, if someone is interested in contributing.

An alternative to ResHacker, XN Resource Editor, http://www.wilsonc.demon.co.uk/d10resourceeditor.htm
Windows only I think.

Implemented the ability to maximise or fullscreen a GTK window

I squeezed both maximising and resizing into the dialect, but the 
expressiveness is getting tight

IIRC, you'll present Red on 09/12? (Syllable conf?)

Are your bindings ready for the show?

I hope they will be ready for the show, but they don't exist yet 
:-)

Adrenalin is the best drug to make them on ;-)

Oh, I see :-)

Thnx for the answers.

By the way, I added an extra error message when the icon file cannot 
be loaded

I have a basic binding with OSM GPS Map working

A simple OpenStreetMap browser goes like this:

#include %OSM-GPS-Map.reds

gtk-view [
	gtk-maximize
	"OSM GPS Map Browser"
	osm-gps-map ogm-new-osd
]

I've got a basic binding with LibChamplain to work, too
