[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

This trigger an error when using FillInTheBlank for exemple. Doit: FillInTheBlankMorph request: 'enter something' creating an empty method updateVisualState: in SimpleButtonMorph seems to solve the problem although.

Hi guys thanks to matthew I finally understood his optimization. The entry point is MCPackage>>snapshot I published a slice in the inbox. If you can try it, look at the changes and let me know. I did some experiences and could load moose which start to be complex but I may have done some mistakes. Stef PS: having real package will really make all that much faster. I will regularly to the TaskForces the code for a new package class.
