Is it compiled with C bindings? (length? == strlen( ))?

Compiled with the current default settings.

So yes, with C bindings.

readelf says that alloc, free, memset, memmove, strlen are imported 
in the binary.

malloc*

Steeve: which system image file have you used?

Great! :)

I check it

SyllableDesktop-0.6.6.i586.iso

I am currently working on runtime error catching. I have successfully 
redirected default handlers for SIGILL, SIGSEGV, SIGFPE on Linux, 
but on Windows, the systems seems to ignore my handlers (using signal( 
) function). So I am currently testing with SetUnhandledExceptionFilter() 
(http://msdn.microsoft.com/en-us/library/ms680634%28VS.85%29.aspx)

If anyone has experience with that API on Windows, advices and tips 
are welcome. :-)

Steeve: I failed to install that version too, but here are special 
install images for Vmware and VirtualBox under "Emulate Syllable" 
bar here: http://web.syllable.org/pages/get-Syllable.html#installation-CD

Thanks, I'll try it

My Syllable image on Vmware works well (as long as I keep the mouse 
in the VM during the boot sequence, else it fails to be detected).

Btw, How do you use a Vmware image instead of an iso one. I don't 
see any option to do so with VirtualBox

You just do from menu: File->Open.

(on Vmware)

Hmm...

Great to see continued progress on Red!

Thanks Gregg, we are currently reaching the first milestone of the 
project with a fully capable Red/System language, just a few more 
implementation fixes, the specification draft to complete, and I 
will declare it beta (means "usable" for real work).

Cool news :-)

Steeve, did you use the VirtualBox boot entry?

hello-syllable.bin confirmed working on the Syllable Desktop development 
build. Thanks to Andreas

The INTERP section can be removed from the binary because it is not 
applicable to Syllable

This removes the last barrier for me to start using Red for real 
work :-)

Is Red is just Linux at the moment?

No Win32

also Win32

And MacOSX

The aim is to be cross platform including ARM support

and does it have a console?

like the rebol console?

Windows, Linux and Syllable, no Mac

No console, but you can just use the system's console

well this is very cool!

BSD definitions are currently being entered into Red, so maybe the 
platforms list is already out of date :-)

It should be quite easy to get it to run on the BSD systems from 
the current state

I tried to write a console input function (no one is available up 
to now AFAK).
This one works (for windows):
#import [
	"kernel32.dll" stdcall [
		ReadConsole: "ReadConsoleA" [
		  	handle		[integer!]
		  	buffer		[c-string!]
		  	len			[integer!]
		  	read		[struct! [value [integer!]]]
		  	reserved	[integer!]
		  	return:	[integer!]
		]
	]

]

stdin: GetStdHandle WIN_STD_INPUT_HANDLE
__read: struct [value [integer!]]
	

input: func [s [c-string!] return: [c-string!] /local in][
		;in: "" ; don't work
		in: allocate 255  ; must be freed after !
		prin s
		ReadConsole stdin in 255 __read 0
		a: __read/value - 1; because of the line return symbol \n
		in/a: #"^(00)" ; necessary to add it !
		in
	]

; usage :
res: input "enter a string : "
print res

my questions : 
- is this correct ?
- how and where de-allocate the c-string ?
- why the end-string symbol is not added automatically ?

My C library binding has a range of input functions

I don't know if your code is correct, because it's Windows specific. 
It's quite possible that the Windows functions don't close strings 
with the trailing zero. My impression is that Windows wasn't originally 
built on the C standard library

The memory you allocate in your input function is returned from the 
function, so it must be freed outside the function, after every call

Have you tried the input functions of your C library binding ? I 
tried input-line (under windows) some time ago, and it did not work. 
At that time, i did not try to allocate the c-string

Under windows, the problems with input-line (which uses gets) are 
probably the same as those that I faced in my implementation : to 
allocate the c-string buffer, to terminate the string properly.

man gets:

BUGS
       Never use gets().

:)

I agree, should use fgets

Since this is open source, I was thinking to let the community do 
the testing. Thanks for the report :-)

I was afraid the gets type functions are implemented as macros, so 
that may well be the problem. The thing is that I can't fix it by 
using the fgets type functions, because Red can't import the standard 
file descriptors such as stdin yet

We talked that over with Nenad and it's planned
