Your fossil repo is very hard to follow
Kaj

[7586x4]
You wanted a direct file link
You can also download as one package:
http://web.syllable.org/news/2012-11-18-20-47-Red-high-level-programming-language-first-alpha.html
It's a binary repository. The examples are in the source repositories
GrahamC

[7590]
ah.. linux only
Kaj
8-May-2013
[7591]
No, why do you think so? The first link shows folders for all platforms

I was looking for hello and increment in the windows folder

Those are not separate programs, they're COMMANDs in the R3 bridge 
example. And there's no binary for that
GrahamC

Ok you lost me again
I'm not seeing anything named r3 bridge

See above:
http://red.esperconsultancy.nl/Red-REBOL-3/dir?ci=tip&name=examples
Most of the I/O examples are in GTK programs:
http://red.esperconsultancy.nl/Red-GTK/dir?ci=tip&name=examples
GTK-text-editor has reading and writing to files and URLs
What I meant when you asked for I/O are the red, red-core and red-base 
interpreter binaries. They're in the Red-test repository, the first 
I gave you

If you have time, a blog/tutorial on how this works would be great
Kaj

[7604x4]
I'll be setting up a website for them later
Doc is keeping me occupied with coding :-)
Until then, the basic documentation is here in Announce
If you start one of those interpreters, the I/O is very simple: READ 
and WRITE like in R2
GrahamC

so you can do cgi?
Kaj
8-May-2013
[7609x2]
Yep, has been possible for some time
Both interpreted and compiled
GrahamC
8-May-2013
[7611]
got a red example?
Kaj

[7612x3]
I/O is currently text only, UTF-8. There are %file literals, but 
url! needs to be written as string! for now
For CGI? No, but it's quite standard. Just PRINT the output. There's 
also GET-ENV to get the request environment variables, and you can 
probably get POST input with INPUT
You can test Red I/O on Try REBOL. It runs the red-core interpreter
GrahamC

I'm running your GTK+ Browser and print buttons do nothing?
Kaj
8-May-2013
[7616]
Did you run it from a terminal?
GrahamC
8-May-2013
[7617]
Nope
Kaj
8-May-2013
[7618]
Then where did you expect to see the output? :-)
GrahamC
8-May-2013
[7619]
on my printer :)
Kaj
8-May-2013
[7620]
I thought you would say that, but nothing is what it seems in computers 
;-)
GrahamC
8-May-2013
[7621]
which is why we, who are not intimately involved in this project, 
need more detailed docs :(
Kaj

PRINT has been standard in REBOL languages for a decade and a half, 
and half a century in other software...
GrahamC
8-May-2013
[7623]
And in View brings up a console to print to
Kaj
8-May-2013
[7624x2]
Only on Windows, so that's non-standard
Anyway, if you try GTK-IDE, you'll get output in the window

LOL, nice exchange - where have you expected print to happen? - On 
my printer :-)

CGI is possible indeed. I did a small tutorial a while ago: http://arnoldvanhofwegen.com/blog/simple-red-cgi-scripting-possible/
GrahamC
9-May-2013
[7628]
Do you want to add using it with GET and POST ?
Arnold
9-May-2013
[7629]
Very much so and connecting it to my MySQL database as well! But 
that is not yet possible at this time. I do not see a use for a form 
if I cannot save information from it.

R2 has all these possibilities, on rebol.org are various examples 
of scripts. For Red we might train our patience muscle of finance 
Nenad in the 'right' direction.

We can finance Doc anyway, but - he knows his priorities, and imo 
CGI is not one of them right now :-) Well, Red still needs some other 
basic stuff, namely objects, I/O (files, networking), parse ... we 
are getting there, it will just take some time ....
GrahamC

Kaj says CGI is possible using get-env to retrieve the request data

CGI support is trivial, you don't need me to add it to Red.
First release of prototype low-level bridge with Java world:

https://github.com/dockimbel/Red/tree/dyn-lib-emitter/red-system/bridges/java
This is a low-level interface suitable for Red/System. Red will have 
a higher-level abstraction layer for interacting with Java.
