[squeak-dev] Cuis updated to #0204

Hi Folks,

I've just updated Cuis to #0201. As usual, the files are at
www.jvuletich.org/Cuis . In addition to the recent enhancements on black
text over colored backgrounds, I also enhanced greatly colored text over
any backgrounds. Both do proper subpixel alpha blending now. I had to
come up with a few tricks for this to happen using just the old BitBlt
rules :-)

There are also preferences to disable subpixel AA for colored and black
text. And they work reasonable well on all bit depths. Looks
surprisingly nice on 8 and 4bpp, and is usable even in 2 and 1 bpp.

Hope you like it.

Cheers,
Juan Vuletich

opss, forget my previous mail then. Seems that I tried to download the
older versions, just when you was replacing them.

See you.

Just wondering if there are any examples floating around out there using the LightWidgets to build a simple UI...

I need to prepare some. All the code using LightWidgets I have is part
of a commercial application (a stand alone video player) and I can not
publish it.

Re: [squeak-dev] Cuis updated to #0204

Thanks.

BTW, I really DO like how snappy is! It doesn't feel "sluggish" at all.

I also like how simple it is; for the first time I feel like I can get into a system and get my mind wrapped around what is in it...

Take care,

Rob

Re: [squeak-dev] Cuis updated to #0204

I noticed in the screen shots on the parallel Pharo post that you have color syntax highlighting...how did you turn it on in Cuis?

It is not syntax highlighting, but color pretty printing. On a browser,
click on Show... (rightmost button) and select colorPrint.

Could we have some screenshots? at least to see it!!!
I'd like to see what you see when you see your fonts and screens :)

I'll try to get permission from the company on Monday.

BTW, at http://www.jvuletich.org/Cuis I uploaded some screen shots of
Cuis with and without subpixel AA and at various Display depth, for
those too lazy to actually download it.

Not to be nit picking but being it anyway...
In the SubPixelAA pictures in the Workspace on top I see white pixels in
the f, t, 1, B and s....

Karl

I see some artifacts on the subpixel

You are right! It is in the 32bpp image. Of course you don't see those
in Squeak, it is a problem of how I saved the PNG file. I fixed it now.

The details... The alpha channel of Display is ignored by VMs. So we
don't pay much attention to it, but it usually contains "garbage". This
was noted by people using composing window managers in Linux. You see in
the png that I evaluated 'Display fixAlpha. PNGReadWriter putForm:...'.
That fixed the alpha channel for the whole Display. But it seems that
when evaluating, Squeak redered the selected text again, creating the
defect you noticed.

hello,

I'm trying to load my code in Cuis but I'm stuck in the first steps: how
do I install Monticello in Cuis ? I tried version 4 from
http://map.squeak.org/package/ce8c6c45-9439-4887-a46f-eae4dcd16d46 with
no success, and I don't feel like testing all the different versions, so
I figured I better ask here.

More generally, some pointers about the ways to load existing packages
in Cuis (or at least to determine if it's possible or not) would be
appreciated.

Re: [squeak-dev] Cuis updated to #0204

May be I'm wrong, but I not tried to install Monticello.

I generated .st from my classes, created a new changeset on Cuis,
directed the changes to this new cs, and then filein my code, fixing
the problems using the debugger.

Is the work style of the old times! full changeset use.

My 0.02.

Using MCInstaller from Squeak Map, I've been able to import .mcz files.

I've installed Swazoo (demo works), Aida Web (demo craps out on some
multilingual thing), and KomHttpServer (simple ModuleAssembly example
doesn't work).

It'll be nice if Aida Web or Seaside runs on Cuis.

Thanks Pierce! I'm sure this will be useful to many people.
