Nice result, you should publish it on rebol.org.

CureCode/R3 is on a linux server. I guess there are font issues?

it could be bypassed...

unless sens [bottom: 0 send: true] <= typo in "send:"?

try this on linux...

    size: 300x200

yes typo

If you can add barcharts too, that would be nice.

I think that Carl would be interested in such a library.

He asked me once for one that can draw pie and bar charts such as 
those from google.

I think that he would be seduced by the small size and elegancy of 
your code.

it's a first thought, could be optimized i guess...

Linux (Ubuntu 8.04 under Vmware) : 
- 1st version: drawing ok, but no text

- 2nd version: no pie chart, no text, only 1 line (first one in list 
maybe)

hum...

you tested with R2 ?

would you an R3 version better ?

R2 only. I can't use R3 for my projects.

New version, i build images from texts, it should work on linux as 
well.
And you can change the font used as well.

It works on Linux. Pie, texts, lines, everything is there.

You should make a library with that code and post it online somewhere 
with short doc/examples (could be rebol.org e.g.).

Getting garbage at the top of the page on every page of CureCode 
- more with each view.

This is on http://curecode.org/rebol3/

It's caused by a missing copy ....

Have to reset Cheyenne ...

The garbage is gzipped data ....

I saw this on my own server a few days ago ...

wow, its getting pretty insane!

I've seen this a lot outside of Curecode. Never figured out what 
it is.

Looks like Cheyenne is trying to create a new form of ASCII art :-). 
First time I see that on Cheyenne. Will reset the server at once.

Worker processes reset, seems back to normal now.

seems there is a copy "" missing somewhere... I could see the last 
page viewed on cheyenne.org just above the curecode page last time 
I visited it.

(or a clear missing)

I'm wondering why this garbage is showing up now instead of a few 
weeks ago when I've upgraded the server.

Henrik ... no idea when you've seen this issue?

It only occurs to me after I've been making changes ... not in the 
normal course of events.

hasn't happened since I reported it in March when I was setting the 
response buffer.

Until the other day.

After a quick code and trace.log files inspection : there's no missing 
COPY, it seems related to a complex chain of events preventing the 
RSP output buffer to be CLEARed before re-use. I found a potential 
flaw in response/include, if the included script raises an error 
in a way that's not  catchable by the RSP execution system, it can 
prevent the output buffer from being reset. In trace.log file, I've 
found an error at 00:53 AM from a rejected SMTP connection using 
SEND function (not the new builtin MTA) that could be the trigger 
for this issue.

Probably why I only see when debugging faulty rsp code.

Graham, only during development. Cure was a restart of the server. 
From Doc's post, it seems he knows what to do about it.

CureCode service will be interrupted during a few seconds now in 
order to upgrade the server.

Upgrading also PHP to v5.2.11 on the same server...takes a bit more 
time.

It's amazing how much time it takes to compile PHP...

The number of modules included on the default config is insane.

Stopping Cheyenne...

Restarted. Everything seems ok.

Doc, on the login page, could you add id attributes to the login 
and pass tags? I'm guessing that is why password saving isn't working 
in Chrome. The user name is being remembered by forrm completion 
(which is a separate function in Chrome), but perhaps password saving 
can't find the user name and password without having an id to look 
for. Setting the id for tags the same thing as their names might 
solve that problem.

I was comparing source between CureCode and other sites that work 
with Chrome. The missing id attribute is the only difference seen.

we are over 1000 tickets. Looks good :-)
