by kilon alios Sept. 15, 2014

Sept. 15, 2014

So I got Command Shell from the configuration browser in Pharo 3 and it looks like it ignores the font size I have set in preferences , why ? The font it uses is too tiny I can barely make the letters, anyone else with same issue ?

Yosemite & Pharo
by Yuriy Tymchuk Sept. 15, 2014

Sept. 15, 2014

Hi pharoers, so Iâve installed Yosemite beta and: 1) there were no problems with Pharo by now 2) sometimes Yosemite lags in general (on rich 3D graphics for e.g.) and battery life is worse. 3) the most important thing that Iâve noticed: there are no black bars if full screen mode. Is an improvement in Pharo, or just how Yosemite works? Cheers. Uko

Hi! We're sending this automatic email twice a month, to give the community an opportunity to easily know what's happening and to coordinate efforts. Just answer informally, and feel free to spawn discussions thereafter! ### Here's what I've been up to since the last WhatsUp: - $HEROIC_ACHIEVEMENTS_OR_DISMAL_FAILURES_OR_SIMPLE_BORING_NECESSARY_TASKS ### What's next, until 2014-09-30 (*): - $NEXT_STEPS_TOWARDS_WORLD_DOMINATION (*) we'll be expecting results by then ;)

AlphaImageMorph performance
by kilon alios Sept. 14, 2014

Sept. 14, 2014

so I sat down to find a good way to import pngs with transparence in pharo and animate them and I ended up to this code morph:= AlphaImageMorph new. morph openInWorld . form1 :=Form fromFileNamed:'/Users/kilon/Pictures/box.png'. form2 :=Form fromFileNamed:'/Users/kilon/Pictures/box2.png'. [(1 to: 100) do: [ :index| morph image: form1 . (Delay forMilliseconds: 2) wait. morph image: form2 . (Delay forMilliseconds: 2) wait. ]]fork. gave me a basic animation then I did the proper thing and I created my own class subclassing AlphaImageMorphing and used stepping every 40 milliseconds (25 fps) to create an animation of 2 frames , frame 1 is image box.png and frame 2 is image box2.png. Both images are 600x600 and contain transparency. Now one morph is fine , seems to work ok and does not raise my cpu much. However when I kept adding instances of the class I found out that after 3 the animation was considerably slow down, pharo also slow down with slow response to my command , when I reached 6 instance I saw failed redrawing of the moprh which was like it was cutting pieces out of the image for a second or so and pharo interaction was quite slow. The cpu one of the four cores were up to 50%. CPU consumption is not bad at all , I compared with playing a youtube FULL HD video which was the same resolution and it was consuming 30% of the cpu. However I wonder if this the best way to do this. Its clear that there is no way with my current solution I can fully animate a big pharo window that is more than 1200x1200 without serious flickering and ideally I should not animate more than 1000x1000 for smooth animation. So is this all ? Are there any improvements I may apply ? Would Athens be faster in this case ? I did not try because Athens is using Morphic anyway so it should be same if not worse.

Which Character Encodings do you want/need in Pharo ?
by Sven Van Caekenberghe Sept. 14, 2014

Sept. 14, 2014

Hi, ZnCharacterEncoder and its subclasses in the package Zinc-Character-Encoding-Core (a standard part of Pharo) have the following features: - proper Unicode Character/String to/from byte(s) encoding/decoding - calculation of encoding size per Character/String - proper handling of holes in tables with exceptions (strict/lenient) - properly backing up one character on a binary stream - simple, efficient, documented - convenience API - optimisations for some encodings Together, they support the following encodings: - utf-8 - utf-16 (big/little endian, bom detection) - null - iso-8859-1 (latin-1) - iso-8859-2 (latin-2) - mac-roman - cp1250 - cp1252 - cp1253 - koi8r - iso-8859-7 - iso-8859-15 The question is, what other encodings do you want/need ? There is already a request to add CP1251. New byte encoders are easy to add, based on the official Unicode mappings that can be found here: http://unicode.org/Public/MAPPINGS (these are automagically parsed). Please help us make Pharo more international friendly. Sven
