World: r3wp

so where can we download this?  :)

I guess all these gfx changes will be part of the next official HostKit 
release.

font quality code - that will have to be done one day, as the View 
app font quality is really not nice. So let's hope that one day it 
will move up in the priority list :-)

(I still need to do a few changes before handing it over to Carl)

Cyphre - what's next on your part? Effect pipeline?

Yes, effects are next on the list. Hope I'll get to them during today.

What's the mechanism of selecting a different charset ?  Just windows 
??

There is no charset selection. You just provide valid UTF-8 codes 
for the appropriate unicode chars, thats all. Also ofcourse you need 
to have font that contains that chars. I was using 'Arial Unicode 
MS' font in the test screens which is a huge font containing big 
chunk from all the unicode pages.

so you can't just type Czech at the keyboard?

maybe you can type Czech, but you have to somehow "convert" from 
local codepage to the Unicode on the go (as you type?) :-) Sorry 
for my very basic understanding of how things might work :-)

I guess you can as the key events will give you that nuicode chars 
you are typing (if your OS supports unicode) but this was not tested 
yet. I'll try it today.

...because R3 already supports char! values bigger than 255 so this 
should work transparent IMO

did you ever figure out how to create GUI event from inside a network 
protocol?

eg. for the purposes of updating a progress face

I did that in R2 so I suppose it works also in R3?

How ?

How about a bounty for the text rendering?


To be honest I don't care to much about better quality at the moment. 
We need a way to display text and some formatting (which works) and 
special chars like Umlauts. That's good-enough for us to use R3 for 
commercial development. Optimal text-rendering is nice to have but 
invest to do it must be covered by some revenue first.

The bounty is possible - but who has the skills to do the real work 
apart from Cyphre? :-) And also - how many man-days approximatelly 
would it take? (research plus implementation).

Who knows how long it takes... anybody complaining about the look 
has a chance to find out.

that contradicts the bounty mechanism, and is typical example of 
bold opinion, which burries and always burried REBOL down ...

No it doesn't contradict nothing. I'm not against bounties at all. 
I'm just against people who complain that first version doesn't do 
everything they want.

Where's the link to the rich text dialect that Richard was talking 
about?

Graham: http://rebol.net/wiki/Richtext

it's probably a good idea to create a wiki page regarding all the 
discovered issues around unicode in View. that way, it's easier to 
create a community project around it.

bounty: This won't cover the total-costs, but it's an additional 
sponsoring from the community that Cyphre can work on it.

Graham: regarding the 'updating GUI from network protocol' question

I have found some older scripts I did and quickly added the progressbar 
to it so you should see how it works.
You can download it from here:
http://www.rebol.cz/cyphre/scripts/r3/net/client.r3
and
http://www.rebol.cz/cyphre/scripts/r3/net/server.r3


just run server and client on localhost and press enter in the client 
console to see how the server shows the progress of upload.

Cyphre, the server link gives a 404

AdrianS: give it another try...it is highly possible Pekr's Apache 
instalation on this server is bugged so sometimes the links works 
and sometimes not ;)

you're right - it looks like a fairly even split between good response 
and 404

yes - still not solved problem of occassional wrong path dispatch 
of Apache in ClearOS :-(   .... Cyphre, you better put it directly 
onto rebol.cz domain ....

is R3 view coordinate system still using Y at top of window?

my guess is yes.


it would be nice to have a switch to allow this to be switched somehow 
within a drawing operation.  some gfx operations are hard to

adapt from normal vector math which uses Y values incrementing when 
looking up

especially if mixing in 3D stuff.

The Y axis is vertical...

but pointing down

0x0 is at the top left which I guess suits text .. but most everything 
prefers 0x0 to be at bottom left

The question is whether positive goes down the axis from the top, 
or up from the bottom.

exactly.

I think it should be the other way around

the issue is that reading starts at the top (in western writing ;)

text is going to largely computed by the view engine

going to be

so why make everyone else compute when doing graphs etc ??

User interfaces are usually composed from the top-left too, in western 
cultures.

its almost impossible to reverse layout when it is expected (and 
much easier to compose) going down.

Just thinking ... dBase used bottom left too

but it would be nice if we could tell the graphics to use up or down 
on the fly.

Postscript does as well.

Composing UIs from the lop left makes sense when the UIs are specified 
using a declarative language that starts from the top left too, a 
language like REBOL.
