[Pharo-project] Smalltalk way of live
by Hilaire Fernandes April 20, 2013

April 20, 2013

I remember a few weeks ago someone shared a video about the Smalltalk "vivid" programming. I want to share this video I did for a DrGeo user willing to hack. I am afraid the comments are in French, so only useful for French audiance. http://www.dailymotion.com/group/drgeo#video=xyv6xv Hilaire -- Dr. Geo http://drgeo.eu

[Pharo-project] [Athens] A new wave of impressionism
by Igor Stasenko April 20, 2013

April 20, 2013

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.

[Pharo-project] files.pharo.org: Moving to new server
by Marcus Denker April 19, 2013

April 19, 2013

Hi, We will change the DNS to a new server. This should be transparent, but of course we never knowâ¦ Stages: 1) Change DNS to point to new server of (TODAY) files.pharo.org get.pharo.org updates.pharo.org 2) Change DNS Server from NameCheap to new provider (TOMORROW) (this will speed up DNS queries ;-) 3) enable CDN for the static files. (NEXT WEEK) Marcus and Camillo

[Pharo-project] How to get the AST Node for a Context
by Marcus Denker April 19, 2013

April 19, 2013

Hi, We implemented this today: #sourceNode for MethodContext. It returns the AST node of context, as part of the whole AST of the method. thisContext sourceNode Returns: DoIt ^ thisContext sourceNode ------------ [ thisContext sourceNode ] value ==> RBBlockNode([ thisContext sourceNode ]) --------------- But even for optimized blocks it works: [ true ifTrue:[thisContext sourceNode ]] value RBBlockNode([ thisContext sourceNode ]) The AST is the one used for code generation, with all information of Semantic Analysis *and* the possibility to get the IR with all information, too. So: [ true ifTrue:[|a|thisContext sourceNode ]] value scope ===> an OCOptimizedBlockScope 4 Marcus

[Pharo-project] DateAndTime bug: we should do something about it
by Igor Stasenko April 19, 2013

April 19, 2013

I tried to find the cause but failed... this thing is annoying.. lets look at the code and brainstorm, about: 1) what happening 2) how we can fix it because i am out of ideas.. and having this crap replicating itself in our images is not tolerable. -- Best regards, Igor Stasenko.
