[Pharo-project] class variable names: initial cap not enforced
by Cameron Sanders July 18, 2009

July 18, 2009

I just loaded the code I have been developing in Pharo into Squeak (closure VM, using 4.10.2-7179web09.07 image base) and it had one complaint while loading: Squeak (seemingly) requires an initial cap on class variable names. [Maybe it allows it... but it popped up the debugger on an MC load.] Does Pharo allow the symbol to start with lower case by design, or was that act of omission? I am merely raising point to make certain it is an act of commission. -Cam

Re: [Pharo-project] New much faster Pharo based on 10379
by David RÃ¶thlisberger July 18, 2009

July 18, 2009

> OK then we should ask david if > - he addressed the check removal > - found the problems with the menus? The check removal I addressed, but the menu problems not yet. I will be away the next three weeks, I can't work on this during that period. But I will look at it when I'm back (Aug 10). But I really suggest to not load OB-Enhancements if you do not want to use the package browser at all.

[Pharo-project] LocaleTest >> #testIsFontAvailable failing
by Philippe Marschall July 18, 2009

July 18, 2009

Hi LocaleTest >> #testIsFontAvailable is raising an exception in my image. The problem is that LanguageEnvironment >> #isFontAvailable sends #fallbackFont to a LocigalFont which does not understand this message. The #realFont of the logical font is a FreeTypeFont which doesn't understand #fallbackFont as well. Cheers Philippe

[Pharo-project] optimizing select:thenCollect:
by StÃ©phane Ducasse July 18, 2009

July 18, 2009

Hi all apparently Collection>>select: selectBlock thenCollect: collectBlock "Utility method to improve readability." ^ (self select: selectBlock) collect: collectBlock so it would be good to avoid to do two passes on the same collection. Any takers? Stef

[Pharo-project] Seaside for html generation
by Schwab,Wilhelm K July 18, 2009

July 18, 2009

Hello all, I am loading a fair amount of code into Pharo, trying to get something working. SIF has worked well so far. The system in question will be Seaside based, but it will start life as a glorified spam generator :) Its operator will use some Seaside forms to tell the system about new data, edit the data to eliminate human errors, and then tell it to send emails based on the remaining data. The emails will be just complicated enough to benefit from html formatting. Yes, the users should be told only to visit the site to retrieve their electronic lashes via Seaside, but that will not happen over night - they haven't thought of it yet ;) The _real_ reason is that I still have to sort out the authentication mechanism. The dumb question: can I simply create a WACanvas, send some messages, and get the rendered html? Any ugly side effects of doing that? I ask because I have code for Dolphin that does the job, but it seems silly to load it into an image with Seaside. Bill

[Pharo-project] questions - class variable convention & Magritte arrays?
by Cameron Sanders July 18, 2009

July 18, 2009

-- Three questions regarding implementing singletons: 1. the convention is to use an initial cap for class variable names, correct? (even though it is not required...) 2. Magritte will likely be used. And I have not dug too deeply. My current (temporary/stepping stone) class is Object subclass: #FaFnBasicKeyLabelAssociations instanceVariableNames: '' classVariableNames: 'TheSingleton' poolDictionaries: '' category: 'FA-FinanceMeta' But I realized that I need even more information than (the basic) Magritte in some cases, and the "Fn" part of the name up above is really referring to financial series (multi-year data). The length of the series varies (depending on what is available). So the question is: does magritte have any capabilities (classes) for handling list display/edit as well as SQL access? Or is that something I will need to build? [And a "yes, read the manual, you idiot!" answer is helpful!] Thanks in advance, Cam

[Pharo-project] Save and quit vs. Save - a clue to performance???
by Schwab,Wilhelm K July 17, 2009

July 17, 2009

Hello all, I've noticed something that seems unusual to me. Choose save and quit, and the writing cursor appears, disappears, and the image is almost immediately gone after that happens. Choose save, and the cursor appears, sticks around for about the same amount of time as for save and quit (this part is a little bit of a stretch), and then the image becomes unresponsive for (depending) one or more seconds. Anything? When combined with comments people have made about the event loop, I wonder whether the system idles when it should not, or something like that??? Sorry if this is a wild goose chase. Bill
