Re: [Pharo-project] Toothpick

I do not know but I will have a look. The problem is that everybody think that logging is simple and reinvent the wheel. And with toothpick there is a documentation and tests.

Re: [Pharo-project] [Preview] Branch test coverage analysis tool for Pharo 3.0 :)

Re: [Pharo-project] [FYI] Athens tutorial

by Igor Stasenko

Yes, this is a known bug actually, which i demonstrated to audience during tutorial presentation.. i/cairo miss the correct font matrix setup.. and i need to see what's there. Cairo caching the glyphs in a strange way (so if you never drawn anything with given font before and your first drawing will use some rotation then everything will be rendered correctly, but if you already drawn anything it will render them like you shown).. I'm going to fix that issue when i come back from Lviv.
