Browser Panes (or is it Pains??)

by Tony Giaccone

I downloaded squeak to try out the UI Generator created by the Haso Plattner Institiute. When I did that I noticed that the squeak system browser has a feature that solves one of my constant annoyances in pharo. The panes of the browser are re-sizeable in the x direction. I can make different panels different sizes. Is there a setting or someway to easily add this capability to the Pharo System Browser? Tony Giaccone

Actors library

by Alex Schenkman

Hi list, Is there an Actors library already available in Pharo? The part I'm interested in is the asynchronous message passing. If it has been done already, why not reuse? Thanks in advance!

Re: [Pharo-users] Anyone knows why Sophie was migrated from Squeak/Smalltalk to Java?

by StÃ©phane Ducasse

I know that several of guys too :) - politics - venture capitalists - Java has good and better widgets so difficult to fight - problem with management in the project (not from the programmers) - when I think I went to sofia to teach them oop..... oh man. What idiot I was. lot more a sad story. Now if we would all join effort to push a decent looking open-source smalltalk with good widgets and good properties (nice xxx framweorks, small image, C integration, better tools, connexion with DB....) then we would all cooler and our projects would get a chance not to be rewritten in Java.

Re: [Pharo-users] Parsing XML into sorted elements

Parsing XML into sorted elements

by Sean P. DeNigris

I want to sort nodes of a certain parent node as they are parsed by XMLDOMParser. The following is what I tried so far. It causes the image to hang and CPU to sweat. I've put half a day in - before I continue, what's the best way to do this? Am I on the right path? It seems very complicated ( I almost feel like I'm working with Morphic ;-) ) The parent node is XMLPageElement which is a subclass of XMLElement, in which I overrode #nodesClass to return XMLSortedList. XMLSortedList is a subclass of XMLNodeList with the following overrides: initialize self nodes sortBlock: self sortBlock. sortBlock ^ [ :a :b | a < b ]. species ^ super XMLSortedList. There is also XMLSortedList class>>collectionClass ^ SortedCollection. The above overrides XMLOrderedList's use of OrderedCollection. I refactored XMLOrderedList by pulling all references to OrderedCollection into this method. Thanks.

Problem with FS Git

by Simon Denier

I'm playing with FS-Git, see how we can use it to browse/extract information from a Git repository. Difficult to get started without a bit of information, but after a while it's ok I have one minor remark and a potential bug: 1) it would be cool to have the timestamp of the commit 2) when trying to recursively browse parents the commit tree, I stumble upon a DNU in GitPackedObject>>unpackRefDeltaContent unpackRefDeltaContent | s delta base | s := (GitObjectSignature loadFrom: file) resolve. "---> (GitObjectSignature loadFrom: file) returns an Integer, which can't answer to #resolve " delta := self readDelta. base := pack packedObjectAt: s. self applyDelta: delta to: base.
