This is a good question.

pi with 1000 digits

by Alain Rastoul

Hi, Just for fun, to see how Smalltalk handles precision, 1000 decimals of pi in 10 lines of code. (arctan is redefined not to use floats, change 1000 to 100 for quick result, any variations welvome) in a workspace: | arctan pi | "arctan(x) using Taylor formula" arctan := [ :x :n | | r s | "x must be a fraction- n is the length of the serie" r := (0 to: n) inject: 0 into: [ :sum :k | sum + ((-1 raisedTo: k) * ( x raisedTo: ((2*k) + 1)) / ((2*k) +1)) ] . r ]. "pi using Machin formula" pi := (16* (arctan value: (1/5) value: 1000)) - (4*(arctan value: (1/239) value: 1000) ) asScaledDecimal: 1000. pi inspect. Cheers Alain

Updated Configuration packages for PharoMorphicView

by S Krish

Details are posted in: http://skrishnamachari.wordpress.com/2012/02/09/pharo-morphic-view-framewor… hopefully cleaner and easier for anyone to load and check out.. PharoMorphicView-Core-App : is a basic package and PharoMorphicView is the full pack. Trying to now wade through the Specs / Presenty / existing capabilities which I can merge with but overall very interesting first time run up with Morphic Experimental Run, but quite usable overall.... plugs in hand in glove with existing primitive morphs. Easy too to get some newbies started with Morphic UIs.. PS: Once comment was nice to hear.. Few new trainees found working in Pharo easier than starting up with VisualAge.. !..

Re: [Pharo-users] Pharo Morphic View Application Framework

by S Krish

The PDF documentation of the framework. Obliged for review/ read and comment and try out the first release.. Ben, I have done a first read of the Spec and I will get my head around how this should be converge.. Will work on that. Though I must note that the spec framework I have laid out is simplistic, flexible and uses the current framework of classes/ morphs without the ValueModel wrapper. Perhaps there is a common ground there, but I would like to emphasize on flexibility of spec and explicit construction to mix and built out has been central to the thought process.

Re: [Pharo-users] Pharo Morphic View Application Framework

by S Krish

Primarily for the view spec framework if I want it purely segregated it would only require the AbstractMorphicView class and can work absolutely independent of the rest of the classes you see, with removing the initializations for MorphicEventHandler/ MorphicMouseHandler in the accessors. ****************** Will provide a doc / little better explanation by weekend. Immediate answer is, this is just not for Morphic View but adds up other capabilities as I mentioned intrinsically to a created application, including: * Configuration based constants, Logging, Translation, mouse/ keyboard handlers on a view level, NamedPrototype and a common Object class for such apps in PharoMorphicObject * subclass a basic MorphicViewController to add a SupervisingController capability as per MVP explanation by Martin Fowler. * MorphicViewEventHandler and MorphicViewMouseHandler are for default keyboard shortcuts and mouse handling at the view level over and above per widget. many of these capabilities I am wanting the framework to posses, is standard for any small/medium/large enterprise application to have. I do see your point though .. a package segregation can be done with probably just one or two classes for the basic view framework and then add packages that have incremental needs fulfilled can be done to reduce fortitous complexity up front.
