[Etoys] Quick testing of Etoys on Windows7
by Korakurider 14 May '09

14 May '09

Hi all. As Rita is trying to run Etoys on Windows7 (discussed in squeak-dev), I also tried it :-) I had to make small twaek on installer script; It checkes windows version and change file layout and replace some file (browser plugin). The trick was Win7 has its own version number "6.1" that the script was't aware of, (Vista is 6.0). Win7 is very similar to vista, so I made the script do same stuff for win7. With modified installer, Etoys is installed successfully, run without gotchas during making security key, run in IE8 (without protection mode though). This is just result quick testing.,, I will test it extensively. How can I contribute the modified scripts? /Korakurider

And, here is an abbreviated steps to take: - Turn off eToyFriendly preference. - open a workspace from the world menu. - Say, if you know the class of the graphical object, type: TheClassName allInstances and press Cmd-i to get the inspector. - Look toward the end of list (perhaps), and find one instance you think it should be reclaimed already. - Select the instance, and from the context-menu, and select perhaps "explore pointers" (or my favorite is "objects pointing to this value" as it is "leaner"). - In the pointer explorer which shows the objects pointing to the graphical object, or the inspector, repeat the cycle to understand the graph of objects around it, and think which other object(s) is/are the root of cause. -- Yoshiki

[Etoys] [Fwd: [squeak-dev] Fwd: A little font rendering speedup]
by Karl Ramberg 19 Apr '09

Maybe for Etoys, too? I saw a speedup from 8026 to 7558 with about 10 windows open. What do others think ?

Since the code, which using fast primitive looks like following: self primDisplayString: aString from: startIndex to: stopIndex map: font characterToGlyphMap xTable: font xTable kern: kernDelta I thought, why one would return nil in ( font characterToGlyphMap ). Since #xTable in StrikeFontSet implemented as following: xTable "Answer an Array of the left x-coordinate of characters in glyphs." ^ (fontArray at: 1) xTable. i think it is safe to do similar in characterToGlyphMap , this allows the primitive to work w/o failure, because otherwise, if you look at implementation of primDisplayString: aString from: startIndex to: stopIndex map: glyphMap xTable: xTable kern: kernDelta in fallback code it does same thing again (and ignoring glyphMap at all, btw). To bench a difference, leave a couple of windows with text in world and then do: [10 timesRepeat: [World fullDrawOn: World assuredCanvas] ] timeToRun before change: 645 after change: 545 -- Best regards, Igor Stasenko AKA sig.

[Etoys] [Bug] Closing an Etoy plugin tab in FireFox forces closure of FireFox
by Jerome Peace 18 Apr '09

18 Apr '09

Hi all, As I continue to explore squeak/etoys in a new enviornment ( Ubuntu 8.04) I keep come upon surprises. This is the latest. There is a bug report on Jira. Though I don't think it got filed under the etoys catagory. This seems like a problem with the embedding script. It doesn't matter whether I have exited etoys or it is still running. When I close the tab the browser abruptly quits. When restarted, it will politely ask if I want to restart the last session. If I reply yes, I am back in the same situation. Quit etoys will again quit the browser. Does someone know a gentler way? Yours in curiosity and service, --Jerome Peace
