Are you sure you run the latest ubuntu, the latest 4.0 image and the latest Pharo virtual machine? Did you follow the PPA installation guide on: http://pharo.org/download? In any other case the debugger is your friend. Step through the methods tell us where exactly it hangs (which call with with parameters). Thx T.

libSDL2 and OSWindow

by Nicolai Hess

What is the current state of the SDL2 / OSWindow integration? There are some *open* bugtracker entries, although SDL and OSWindow *are* in the latest vm+image. On Ubuntu 14.04 64Bit OSWindow new does not work, it complains it can not find libSDL2, but it is there On Windows 7 OSWindow new opens a window that is mainly off the screen, only the bottom right corner is visible. nicolai

Re: [Pharo-dev] athens font rendering and subpixel antialiasing

by Nicolai Hess

It looks like this gray-scale vs. colored subpixel antialiasing is an issue on windows. I did the same test on linux (Ubuntu 14.04) (screenshot attached). But still, the font rendering with the freetype plugin (morphic way) looks better than the athens one. any ideas/help?

Re: [Pharo-dev] Why this hangs the VM?

Now the following works okay... Behavior new basicNew So something in its #initialize makes it not crash. Rolling out Behanior>>initialize and commenting out a line at a time to get the minimum statements to prevent crashing results in the following... behavior := Behavior basicNew. "behavior superclass: Object." "behavior methodDict: behavior emptyMethodDictionary." behavior setFormat: Object format. "behavior traitComposition: nil." "behavior users: IdentitySet new." behavior basicNew. So the VM will crash if you fail to #setFormat.

Re: [Pharo-dev] HELP WANTED: improve Dark Theme

There is a bit of theory behind about how to choose a nice color schema. It would be _great_ that the crew behind this effort have a look at it. we do have a good dark themeâ¦ probably not the one you like the most, but is good (based in darcula for eclipse) :) > > Here is a set of colors that works well for the dark theme.

Now, this is a problem in eclipse itself who didnât had a dark-theme either until recently. Now, I know they added a dark-theme and a corresponding set of icons (a set that can be displayed correctly both in white and black backgrounds), but I cannot find the icons. So if someone knows where they are, Iâll gladly replace them. >> I know in an ideal world we will have our own set of icons, but that requires a lot of effort and design talentâ¦ so in the mean time, I think eclipse icons are doing a good job :) >> >> cheers, >> Esteban > > -- > _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: > Alexandre Bergel http://www.bergel.eu > ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;. > > > >

This time the bloc world only opens in the upper left corner extent ~ 100@50. I can open a world menu in this area :) , but I can not make it larger. And after some time, it crashes the vm.
