Look for uses of Preferences subPixelRenderFonts, e.g. installStrikeFont:foregroundColor:backgroundColor:. There's a non-local return in the default path on preference access. So not having subPixelRenderFonts a defined preference method creates lots on noise when doing VM debugging. > in Pharo Preferences are not anymore... #subPixelRenderFonts is send to StrikeFont and just returns true (the default of the Preference). I think the idea was to add a Setting later if someone requests it... and nobody ever did. So maybe we can simplify that method a bit. Marcus -- Marcus Denker -- http://marcusdenker.de

[Pharo-project] Morphic operation in startUp sequence

Hello, What is the proper way to do morphic operation when an image is loaded. I am not sure it is safe to do in the startUp sequence. Thanks Hilaire -- Dr. Geo -- http://www.drgeo.eu

[Pharo-project] Any theme or settings that will speed up a Pharo 1.3 image?
by Stefan Marr March 19, 2012

March 19, 2012

Hi: When trying to debug a Pharo image with a VM that is heavily instrumented with assertions and runs without any compiler optimizations turned on, it is crawlingly slow. (The good old MVC based image is blazingly fast in comparison) Are there any tricks to reduce/disable all the possibly fancy things like transparency, code completion, syntax highlighting easily? I already disable the code completion, and syntax highlighting. I also switched off things like animations, rounded corners, and switched to the Standard Squeak theme. Still, non of these cosmetic changes gave me the noticeable performance gain I had hoped for. Is there anything else I could try to reduce the amount of work the image is doing? It blinks the cursor in a text field in the speed I would expect. But as soon as I start typing, or try to interact with a window, it feels like I can go for a walk before the image is done.

Dear Pharo Friends and Supporters We worked a lot with INRIA lawyers and tried a lot of different scenarios. We arrived to a setup that make sense now we would like to get your input. Please have a look at the following powerpoint presentation and feel free to comment! We provide some sketches for the consortium fees and benefits for you. But we need your input! If you are not in the mailing-list: send us a mail to board(a)pharo-project.org. Remember that what we want to achieve is to be able to pay one (or more) full time engineer to help us improving our system and making that our future is bright. Since it may be difficult to follow closely our vision, dreams and current development efforts you can read the Pharo vision document. https://gforge.inria.fr/frs/download.php/30436/PHARO-ENG-V4.2.pdf https://gforge.inria.fr/frs/download.php/30434/PharoVision.pdf The Pharo Team Remember: The best way to predict the future is to invent it.

[Pharo-project] Extending SystemBrowser
by Ezequiel Lamonica March 19, 2012

March 19, 2012

Hi everybody, I have some problems to extend the SystemBrowser. I want to add a panel at the left of package panel to list products. Product is a new concept that I created to manage a group of packages. For example, Pharo is a product and Seaside is another that depends on Pharo. This is the path that I want to follow: Products -> Packages -> Classes -> Protocols -> Methods I know in Pharo 1.4 the systemBrowser will be changed but I have a proof of concept early and I have to show something working integrated in Pharo 1.3 image. What could I do to start? Any advice?

Hi I'm updating the configuration of citizen to 1.4 and I need to load Seaside 30 When I use the MetacelloRepository I get isTranscriptStream question because 1.4 does not have TranscriptStream Pier for Pier I have a problem since it reference to ImageSegments. Did any of you produce a correct configuration for Pharo1.4? Stef
