We just released our first R3 based tool. See: http://www.saphirion.com/development/heat-map/


The tool gives you an editor to build hierarchical structures / layouts 
where you than can map given information criterias (Skills, Performance, 
...) into visual recognizable values (color, line width, ...).


We use this tool to visualize complex situations on one page. The 
values could be feed from a database or other source in real-time 
and the visualization will update immediatly.

Is there a new %test-demo.r3 file? The old one doesn't work anymore.

We have a new testimonial for our NLPP product (R2 based) from ZF: 
http://www.saphirion.com/innovation/nlpp/testimonial/(German)

Has anyone noticed that http://rebol.comis down?  Not a good sign.

I just noticed a few minutes ago when my trusty "do http://rebol.com/speed.r"
failed.

It looks like a bill wasn't paid.

Why?  Its a non-executable script so just shows for me

Thank you, I found it a fun puzzle too when I found some of them 
in a summer logic puzzle book. I then found a puzzle collection with 
most of the puzzle games (Simon Tatham's portable puzzle collection) 
except this one so I built one myself using Java. One of the first 
puzzles I had to solve I solved with 6 mirrors but you have to solve 
it using 7. It was quite a puzzle to me thought I made an error somewhere 
but luckily I solved it!

it would be nice for numbers to have a different appearance (bold 
white ?) telling us which one are paired.

I thought about that too, label font color can be set, but I was 
afraid it would slow down the app. That is why I chose to build the 
extra mirrors as a seperate layer to show on top of the grid-layer 
and the unchangeble mirror-layer.

oh don't worry about speed, its a really small app with verry little 
to update... 


I've got 250000 line draw blocks which refresh 10 frames a second 
interactively  :-)

There is a small problem. I test if the solution is found, the moment 
it is found to be not the case, evaluating stops. I can rebuild the 
working.

I can rebuild the working.
   is there a word missing there?  not sure I get it.

Hello I have a new version 1.05 'ready'. Added languages and a preferences 
panel. Only the save option to save preferences I did not fill in 
this one, because  first  of all location of this file and secondly 
I had doubts if it is needed. http://www.arnoldvanhofwegen.com/stuff/mirror.zip
It contains 3 files.

Warning: new discussion possible!

Well this was hard! 1.06 ready on zip space but because I have 0.0 
trust in Macs zippabilities I also placed all files in http://arnoldvanhofwegen.com/stuff/mirror/

The files are Windows Latin 1 format for all special characters to 
display ok, except in REBOL itself where they are a mess ):

Hi all,
I am proud to announce: RebRep | print with your RepRap
http://rebrep.blogfree.net
It is a Windows-only program.

Please let me know what you think of it (even if you don't YET have 
a RepRap ;) )

Hello everybody: I'm working on rebol2.blogspot.com (take a look!). 
If you want to write an article on Rebol, send me an in email with 
the article and I'll publish it. If you want to see a topic discussed, 
send me an email with a request, and I'll try to write about it. 
My email is [maxint-:-tiscali-:-it]

Look also at this page: http://www.maxvessi.net/rebsite/wr/if 
 your site is about Rebol and isn't the list on the left, please 
send me your link; if you know some site about Rebol and it isn't 
in the list, please send me a link.

A new version of the mirror game is available as a zipped file at 
http://www.arnoldvanhofwegen.com/stuff/mirror.zip

This time it is version 1.07. I put a beam in. Click on a label and 
a beam will show up,right click the label or just click the box for 
a new mirror and it disappears again. (It is also becoming a showcase 
for different REBOL techniques applied, though maybe not the best 
(: ) 
Have fun with this version!

InvoiceFox for US was finally serriously released 1month ago and 
a 2 weeks back added to Chrome Web Store https://chrome.google.com/webstore/detail/jjolcoebhfocblfngacoplfgfehdloml

There are a lot of "undocumented" functions, if you kow their purpose, 
please send me an email

I just upladed a new version, I removed a widget accidentally!

I released my first game for the Android platform.

Have fun!

I just placed a first draft of a script to help with compiling Red 
scripts on REBOL.org http://www.rebol.org/view-script.r?script=redcompiler.r
No guaranties ;)

Printer driver for REBOL released on Github: https://github.com/dockimbel/printer-driver

See %tests/ folder for a full example.

Fixes and additions are welcome!

It is far from perfect yet, the code needs a lot of cleaning up but 
I would not wait much longer for you all to have a look at my REBOL 
solution to make a small chessboard application that gives all the 
possible legal moves so you can play a game according to the rules 
of chess. You need the 2 files http://www.rebol.org/view-script.r?script=cbh.r
and http://www.rebol.org/view-script.r?script=chessmoves.rto make 
it work. 

Hope you like it and the REBOL solutions I chose to accomplish this.

Oh by the way it is NOT a chess computerprogram! It does not compute 
any best move of any kind! It just is possible to move the pieces 
playing a game according to the rules of the game.

As you might know, I wrote a R3 book in Chinese, trying to attract 
more people to the REBOL camp. It sells very well so far. But I would 
like to attract more than Just Chinese. So I decide to translate 
it into English and make the English Version free. It's a slide with 
320 Pages. This slide is colorful, beautiful, and easy to understand. 
I would like you guys to help me correct my English before I put 
it to the public. I would also like this gesture to make Carl feel 
the support and love from the community.

Hello, I'm writing a new version of Rebolide, with color syntax higlithing, 
using another rebol script (area-tc) with perfect syntax higlithing. 
I put the new rebolide on github: https://gist.github.com/3635812
, since github works great with Rebol.

However I'm not good as you and I can't understand how make this 
new rebolide similar to the old one, see  the old one on: http://www.rebol.org/view-script.r?script=rebolide.r

My main concern at the moment is to create button to insert code 
in the main area, cut and copy works, but the functions button like 
the old one no.
May you help me?

OK, that link was just a gist,  the repository is https://github.com/angerangel/rebolide

There is a note from Carl on his blog!

Carl, 9-Sep-2012 15:46:54: "I need to apologize all of you for the 
lack of response to your comments. This was due to a funny incident 
that happened on my ranch.


Last week, a few heffalumps burst into my basement and turned over 
the last barrel of 1999 Châtemateloo. Unfortunately, the precious 
liquid flooded telecommunication cables and I lost network connection.

You know me, this is not a reason to give up.


Using a microwave oven, amateur radio, and 4 lines of code in REBOL 
I was able to construct a modem and here I am.


Well, I read very carefully your comments (the first two lines of 
each comment) and I noticed that most of them contain the phrase 
"Hi Carl". I was hoping that I'll find out from them what further 
steps should be taken to save the future of REBOL, but it seems that 
as usual I have to come up with a solution myself.

So, here it is.

I decided to open source REBOL.


Choice of license is very difficult because there are many kinds 
of them. I examined the majority of them, and none meets my needs. 
They are overloaded and too complicated. The only thing I can do 
in this situation is to write my own license. I name it ... Rebolense.

Creating a license is not an easy task, but is necessary.

I'll be working on it soon, so stay tuned. "

There's a growing consenus, Max, that that blog post may be better 
suited for the Humour group.

Message from a yellow Carl

Probably a real blog post is the only way to know for sure.

To add to the idiocy, there's now a message from the real Carl, stating 
he agrees with the fake one

Hi, I have added two scripts today on rebol.org. one is how I plan 
using the mysql driver from Nenad, the other one is reproducing the 
php script on http://www.alistapart.com/articles/succeed/to get 
well formed URL/URI 's and get rid of the ?id=99&stuff='idea' kind 
of links. 

It is not yet really finished for I haven't tested/thought about 
how this works with requesting the indexfile in subdirectories. Also 
if there are ideas how to store and reproduce articles from a database 
using one two or more keywords feel free to put them up.

A first pass at accessing the Etsy API: http://reb4.me/r/etsy


Works similarly to my Twitter API script (a few OAuth differences 
here and there). You can download it, or run it in place (do/args 
... [...Settings...]). As with Twitter, you start with etsy/as and 
go through the authorization process.  It has a few example methods, 
and an open method - etsy/api-call - that can call (as far as I can 
tell) every api function. Will try to document at some point.

Sorry, I mean you should try it on a X11 environment.

why doesn't it support metadata ?   that's a strange limitation

on many database servers there is INFORMATION_SCHEMA adn it can be 
queried like a normal table.

Endo, ADO is a layer over ODBC. ODBC is closer to the db. People 
used ADO because it had an object-oriented API, useful for ActiveX 
languages. ODBC has a lower-level API that was more awkward for OO 
programs to use directly, so they used it through ADO.

OLEDB was sometimes as close to the db as ODBC, or was a layer over 
ODBC. Now, it's deprecated by MS, which is recommending that you 
use the faster, more standard ODBC instead.

I think this is a Rebol forum :)

ChristianE's open-source (yay!) R3 driver chokes on a different and 
larger set of datatypes than R2's, including working with datatypes 
introduced in 2000 that R2 chokes on, like float.

Fortunately we can improve ChristianE's R3 driver. Since I use it 
a lot at work, I need to. I'm just waiting until I have the time 
to spare, which hasn't happened in several months.

ChristianE implements an R2-like API in an R3 port model, and it 
just feels alien, though it does allow me to have more portable code 
between R2 and R3. This helps when i have to have a script extract 
data in R2 because it needs to get text or numeric type data, but 
then close and call itself in R3 to parse that data. My %rebol.r 
is R2 and R3 compatible.

I figured out a way to make an R3-like ODBC API, and have an R2-like 
API emulated when you try to use it in an R2-like way. But then I 
ran out of time, was assigned to other projects for a while.

A lot of the OpenDBX references to SQL Server don't seem to take 
SQL Server 2008 into account, so it's at least 3 versions behind 
now. Comparable to R2 I guess.

It makes a lot more sense to have OpenDBX bindings for R2 though, 
since the lack of Unicode support won't matter there.

OpenDBX is not a full SQL interface to databases, but a database 
abstraction of its own. They're probably not interested in supporting 
other features

Knowing C, it would be better to add it to the ODBC API, at least 
for someone who already knows SQL. That way you can get wider database 
support, since most SQL database vendors support ODBC. Heck, even 
Microsoft is making a free unixodbc driver for MSSQL.

it sets up a tcp listener but I can't find the documentation of their 
line protocol

Wasn't Robert going to create a database driver for R3?

ChristianE's odbc driver for R3 is already a little more useful than 
the R2 one, but needs a bit of work. Being open source, we can do 
the work.

Ha! R3's documentation for its port model is a bit lacking :(

What's missing in the R3 port documentation is best practices examples 
for different usage models. The port model is so flexible you can 
almost use it as a way to create user-defined data types, but we're 
missing complex examples of the most efficient way to use the model. 
That's another reason I wanted to make a real R3-like odbc:// scheme, 
to learn the model better.

Yup. You should see what they have in store for SQL Server 2012. 
It can be run on a fully command line OS, managed remotely entirely 
through PowerShell scripting. And you can do PowerShell scripting 
of MS servers from Linux clients too, reportedly.

PowerShell is a powerful scripting lanugage, but it is a mess, I 
don't understand why they never think about simplicity.

using rebol's ODBC interface, is there a way to get the names of 
the columns in the last select query?  sometimes, we do not provide 
the columns (select * from table) , so relying on assumptions to 
match return values and their columns is quite dangerous.

With ChristianE's R3 ODBC, the initial insert dbport returns a header 
list translated to REBOL naming conventions, though it doesn't work 
right with unlabeled columns. Not sure with R2.

If you want to get the column metadata about a table, use the 'columns 
command:
- For R2: http://www.rebol.com/docs/database.html#section-27

- For R3: http://www.diefettenjahresindvorbei.de/odbc/odbc-docs.html#section-3.8
 though there's an error in the docs, so use 'columns instead of 
'tables

except that SQL actualy does return the column headers, its a pity 
R2's ODBC interface doesn't seem to keep/read it.

Back in 2001 I created an intranet site for a local celebrity by 
making the database tables, then having R2 use the 'columns command 
to generate column lists that were used to autogenerate the server-side 
pages for the intranet. All it took was one function call per table 
to generate the whole site. Restyling the site just meant editing 
the HTML template in the function (this was before CSS was practical).

I may find some time to tweak the R3 ODBC-API a bit if you could 
supply a prioritized list of things that need work. Regarding problems 
with certain SQL types one easy workaround could be to just allow 
all types without direct support by rebol to read them as strings, 
you then could do anything you like withthem. Regarding "R3's documentation 
for its port model is a bit lacking" - I surely won't have any time 
to find out why the port model I used feels alien to R3 without the 
better R3 beeing documented anywhere.

We weren't requesting an update of the port model to you, Christian. 
That can wait until we have a better idea of what it should be.

There was a bug in open with certain kinds of odbc port specs. The 
above code fixes that.

You can't do an R2-style hot-patch of a function in R3, but you can 
replace the entire function with a new, fixed one.

I'm interested in creating a rebol associative db. Terry, I know, 
was talking about one such back in May last year (i think he called 
it rocketdb) - but apart from the altme logs and something on a redis 
google group, i cannot find anything. Does anyone know whether he 
released something or how i could contact him?

for i 1 length? ieflat 3 [either select i1 ieflat/:i [f: select i1 
ieflat/:i append f :i][append i1 ieflat/:i repend i1 reduce [to-block 
:i]]] ;am sure there is a better way of doing this...

what would be useful is to build something like a SPARQL dialect 
on top of this

Thanks Sunanda - have seen those... have not been able to find the 
video of Ron Everett's talk though. Would be good to see it - would 
you happen to have a link?

I think this would be the start of something superb. If we can build 
a SPARQL like query interface on top of an associative db in rebol, 
we could simply point it to any of the open data initiatives and 
then go on the ride of a lifetime!

in R2 map! is there just for compability. map! = hash! in R2.

x: make map! [a 1 b 2]
series? x ; == true (for R2)
series? x ; == false (for R3)

Sujoy.....Link to Devcon 2007 videos.   Link is below, but you'll 
need a logon to the website. Someone else here will be able to advise 
you on that:

I want to change some data in a mysql database from a REBOL (2) program 
using DocKimbel's mysql-portocol.r When I use a .r script from my 
website I can connect to the database. I figured that when I ran 
a script from a console I would be able to quickly test my script 
but somehow I am stopped because the script cannot connect. This 
is the error:
** Access Error: Cannot connect to mysql-01.yourname.nl
** Where: open-proto
** Near:
Any ideas?

and, try to connect from a remote PC using mysql command-line tool.

If you are using Cpanel, there is a section to Grant, otherwise you 
may have to do it manually.

I guess my hosting provider is not supporting the GRANT options in 
database user screens and their supplied phpmyadmin. I think I have 
a trick on my sleeve though with a self installed phpmyadmin. No. 
More luck maybe tomorrow....

There is a Plesk control panel where I can create databases and add 
users/passwords (but no GRANT options) and a webadmin which is a 
PHPMyAdmin screen, that is almost identical to my self installed 
phpMyAdmin 2.6.0-pl2

Does anyone know if there is any problem with using a ":" within 
a http URL, for the *target* part of the path.   

as such, the URL doesn't have any relation to physical disk paths.

ex:

http://mydomain.com/stuff/group:resource

I have the above working on a server, and browsers I've tested do 
not seem to have any problem with the URL, but I'm wondering more 
at large, if there are issues with it, in general.


It will be used  from within applications (java, .net, php & rebol) 
much more than from users manually using it within a browser bar.

rebol doesn't url encode the character, so it seems like its a valid 
character, but I don't want to assume, if some standard toolset doesn't 
like the color in the target.

rfc1738 says ":" is a reserved character for possible special meaning 
in some schemes. It does not seem to have any special  meaning in 
the schemes mentioned in that URL.


But its reserved status means that it does not have to be encoded 
in any URL.

That's the theory, anyway. Practice may show otherwise.

https://tools.ietf.org/html/rfc1738

all the string-based datatype convertion funcs are flawed in some 
un-expected ways.   for example, you can to-word a lot of strings 
which aren't valid words.   


this is why I asked.  Although R2 doesn't complain, it doesn't mean 
tis valid or expected.

Hi, I am looking into OAuth. I see (and thank you a lot for this!) 
that Chriss Ross Gill created OAuth client part in the twitter library: 
http://reb4.me/r/twitter.html, I am reading into it, but does he 
or anyone else know how much additional work would be needed to do 
the rebol OAuth server part ?

For the most part, authorisation is based the parameters of a request 
hashed with a private key.  The trickiest part I'd imagine is the 
initial authentication - providing a safe method for the end user 
to allow the client to obtain and use the key.

End user X downloads Y's app/uses Y's web site; X tries to access 
a function that uses your site; Y requests a temp key from you; Y 
directs X to your site with temp key, X says Y is OK, you give X 
a PIN; X goes back to Y, enters PIN; Y requests the permanent key 
from you.  Y can now do anything on your site on behalf of X.

I am not an expert but I have a lot of experience and also theory 
about various aspects of it because of making my apps grow (and helping 
some others)

I trust the clouddate being watched over, and more I trust it a 100% 
being watched or even analysed.

Some things I just take as is without proof, like the earth to be 
a flat disc ;)

Yes, it's obvius. Frankly it depends on what data you want to "share". 
I like google documents for storing files to edit when I travel ,not 
very important documents. For example: if you would plan a kamikaze 
attack or write a personal diary on your sexual orientation, I didn't 
suggest you to use google documents.

It seems to me that under Red, one marvelous tool which could be 
created would be similar this new one - which I just discovered ... 
at least with my not too long vision  - based on the Cheyenne HTTP 
server, it seems it could be realized using a similar approach, to 
begin with ... http://www.wakanda.org/overview- Also available 
on Github for those interested to look at the code (may be Topaz 
friends - sinc it is base entirely on Javascript).

Yes; they have a good model, but it's all ugly web technologies

I agree but what else could be used - something built aroud the JVM 
- may be ? It must be a bit like Carl's REBOL based vision, isn't 
it ? Entirely self contained to be deployed anywhere but written 
once ...

Yes, all true. I've long been working on a system with roughly that 
model, but we only use it internally so far

It's a web system currently, but it's prepared to support other platforms. 
My Try REBOL site is made with it

REBOL 2 is no use to me because it would never run on Syllable, and 
REBOL 3 still only has a GUI for Windows and Amiga, so it hasn't 
been useful for me to make a VID frontend

(from #Red) - Arnold, which version of Make Doc are you using? I've 
many iterations of MD that I've hacked away at over the years, perhaps 
I'll have something that will be easier to hack?  Most recent version 
I put together for the 'Notes For the Road' site, has some nice features 
- currently hacking at it again for a more ambitious QM project...

Chris, I am stil figuring this out. I want bold/italic/(underline)/(em) 
paragrapphs separated with a blank line (easier to understand and 
no need to delete a routinely typed 'return'-key) h1/h2/h3 img (inline/left 
right center aligned) and a-href, only 1 level of bullits, and I 
think I can come along without numbered sections. I was thinking 
about mark-up delimiters on the beginning of the line like === ==+ 
==- ==* ==#   I kind of liked \note and /note or /code but everybody 
will forget if the first one will be fore or backslashed so I guess 
the indented version to produce code. Plus I want the markup to be 
from a css file. No need to make this within the script because the 
template/and a script can take care of where and which to link to. 
That's about it.

Doesn't sound too onerous - I'd say most of the changes could be 
made to the parser, then tweak the emitter to get the output you 
want. Do you have a sample document? Is this the version you're using?
