[Pharo-project] Cannot load PolyMorph/UIEnhancements
by Norbert Hartl Sept. 23, 2008

Sept. 23, 2008

I tried to load the Polymorph package in a fresh pharo image and I didn't succeed. I tried pharo 10044, 10070 and 10074 image. And I tried loading from universes as well as via monticello. The result is the same: When the Loading progress bar appears it freezes after 10% of the bar is full. It doesn't matter if I load it with 64bit or 32bit (binary) vm. I had no trouble loading the same into a 3.10.2 squeak image. How do I debug the action while it is showing the progress bar? thanks in advance, Norbert

[Pharo-project] Product Brand Pharo

Markus wrote >One question: is the splash-screen really needed? Adrien wrote: >I don't see the point of a splash screen. I completely agree that it is useless in the sense of loading screen showing the progress for the standard pharo image. Maybe it makes more sense for the "slower" TrueType image where a progress bar currently shows the font updates. But this is not possible since the Squeak VM does not (yet) support an updating splash progress in the native splash window driven by Smalltalk code. But a splash can also be done "image side only" anyway. But that's not the point. I suggested to provide a splash screen more from the branding/marketing point of view - even if it is technically useless. At least I want to know what others think about it. A splash screen typically shows the Logo and some version information and people rember/recognize/identify the software through that. Some applications have an option to disable the splash or show it only on the first startup. Eclipse for instance uses a slightly modified splash screen theme for each yearly full release (Europa, Ganymede, ...) - nice idea since the user knows which one is started when the disk is full with different versions. Sure we should drop the splash screen from the technical point of view - but it would be a nice idea to have the welcome screen of each Pharo release with a slightly modified theme to see if it is a core, developer image, ... We dont have to clone native apps/Java IDE's - but at least we can learn a little bit about branding/marketing and how good design can attract more people. Take another example - will you find a Smalltalk IDE with good looking Wizards these days? >From the Smalltalkers point of view (knowing about #subclass: messages) it's technically useless and will bloat the image - but I've seen many newbies blaming Smalltalk to be that complicated the first time they just click around and search for the Class/Package wizard. Squeak is also not very supportive if one needs help - there is a help menu but no real help/documentation. That does not mean we should have the splash screen or spend the whole day implementing Wizards - but at least we should discuss and think about what the first impression for others/non Smalltalkers will be and how we can help them to take first hurdles and enjoy the power of Smalltalk...

[Pharo-project] Halt once; workspace(?) menu
by Bill Schwab Sept. 23, 2008

Sept. 23, 2008

A couple of quick thoughts based on the Polymorph/TT image: (1) Halt-once looks like it is built into the image as a mode. It is a VERY useful concept, but Dolphin has long had a goodie that provides the feature as a class, used something along the lines of the following: abandonHopeAllYeWhoRaiseEndlessWalkbacksHere self someUnfortunateConditionDetected ifTrue:[ Once do:[ self halt. ]. " Once reset. " ]. Any takers? I did not write it, but I think we will find it licensed in a friendly way, or it could be easily reconstructed, if not improved by having registered instances, allowing independent conditional breakpoints, and all in code, or as I like to say "done in the language, not TO the language." (2) The extended search sub-menu. At the really picky level (ignore if there is ANY problem with this), it might be nicer to pop out a submenu vs. jumping to another menu. Bill Wilhelm K.

Marcus, I'm fairly certain the problem is in Redmond. It would not be the first thing they botched. I'm just annoyed with myself for not fingering them sooner. By all means though, newbies will encounter it, so protecting Windows from itself is probably a good move. Is Pharo going to adopt the one-click structure? On Windows, I do not much care. The VM "installs" trivially, and shortcuts are cheap. Shortcuts are not much more expensive on Linux, or maybe I haven't learned enough about how to skip steps on Linux. The VM is a little more trouble on Linux, but nothing I can't handle, and I'll gain familiarity as I go. All that said, since there is something that is brain-dead simple on the main platforms, I'm not too proud to use it ;) I do not much care whether we use it or not. If the plan is to do so, I can save myself some hassle sooner rather than later, but whatever you guys want to do is fine by me. Thanks! Bill Wilhelm K.

Got it. My basic algorithm for finding problems usually starts with "what could Microsoft have done to screw this up?" I faltered. In this case, MS could have made a mockery of the file names in the archive, and that is apparently just what they did. I do not care for 7-Zip's user interface, but the engine works. It magically understood the archive (what's that word again, standards???<g>), unzipped all the files, and now everything works. Very impressive BTW. Dumb question: to copy an image/changes between machines, would I simply copy the image and change files (a few levels down in Resources), and leave the rest of the "one click image" alone?

[Pharo-project] Product Brand Pharo
by Torsten Bergmann Sept. 22, 2008

Sept. 22, 2008

Beginners always lament on the default look of Squeak. Hopefully this will change with Pharo and Truetype/Polymorph. Some comments on the pharo one click image: I dont know who builds the custom VM for Pharo - but the icon is the one from Seaside and should be replaced. There are various parameters in the *.ini file to product brand a squeak VM based application therefore I would also recommend to add the folling lines into the Pharo.ini file: WindowTitle=Pharo This sets the window title to Pharo instead of Squeak and QuitDialogMessage="Quit Pharo without saving?" QuitDialogLabel=Pharo adapts the quit message box of the VM. At least on Win32. See http://www.squeakvm.org/win32/settings.html It would also be good to have a splash screen with the logo or some decent looking graphics/logo combination. The splash screen typically is a *.bmp file located in the same directory as pharo.exe and the default name is splash.bmp. You can set up another name again in the pharo.ini file: SplashScreen="pharo.bmp" SplashTitle=Pharo SplashTime=2000 Attached is a modified Pharo.ini and a sample splash file. Just put it in the same directory as the EXE file for the one click install. Do we have access to professinal designer for a good looking splash/website/icons? Are there any plans regarding this?
