I try avoid class-side stuff so I just put #canonicalArgumentName on Class (for instance). So 1 canonicalArgumentName = 'Integer'. You could add Boolean as well, to avoid creating a name like 'aTrue'. I've nicked your idea for Squeak, Sean. And it flushed out a bug in my recent Debugger hackings too! [1] So when I finally get around to porting my "just in time development" hacks to Pharo, there'll hopefully be one less bug in it.

Well, last time I looked (eons ago), in the C code of the Mac SSL plugin, the certificate was not used/implemented. For starters, follow ZdcPluginSSLSession>>#certiificate[:] to find the primitive. Then see ihow/if that actually does something and/or is being used - in the C/plugin code. It would be really great if we could fix this.

[Pharo-project] [Athens] A new wave of impressionism

by Igor Stasenko

Not really impressive (that's why it called new wave) Here is results of 2 days of preparing/implementing and polishing a quadric bezier curve approximation algorithm by series of lines. The red pill.. err fill is polygon consisting purely from lines, the white outline is same quadric bezier, but drawn directly by cairo with stroke width = 5. Cubic bezier , then elliptical arc and then generic parametric functions ahead! :) There is two reasons why i implementing highly inefficient (because of boxed floats) path flattener: - some path segments are not supported by cairo, therefore i am forced to approximate it with something else (and something else is lines ;) - having path geometry turned into silly polygon, there is very easy algorithm to tell if given point inside or outside of polygon so, potentially, this will give use following: - being able to use any kind of curves as path segments (well, it could be a bit slow, but it is up to you, right?) e.g. something like: builder lineTo: 50@50; parametricCurve: [:t | t sin * t squared ] tMin: 0 tMax: 10 to: 20@30 - being able to detect whether mouse hovers over shape or not :) -- Best regards, Igor Stasenko.
