[Pharo-project] New widget
by Benjamin March 10, 2011

March 10, 2011

Hello everyone, I've done a new Morphic widget, that allow to easily switch from a categorized view to a "all elements" view (quite hard to explain, let me give you an example ^^) Gofer new squeaksource: 'SwitchableTreeWidget'; package: 'SwitchableTreeWidget'; load. SwitchableCategoriesTreeExample new openInWorld. If you click on the button or just double click on the tree, you will switch the view :) I wrote that widget to integrate it in a new browser (and if I succeed, to create a new Glamour widget) Thanks in for your feedback :) Ben

Hi Folks! What are the different optimizations Pharo compiler offers? Is there more than a mere message inlining (class, ifTrue:ifFalse:, timesRepeat:, to:do:) ?

[Pharo-project] Issue 3802 in pharo: A strange superclasses if Canvas
by pharo＠googlecode.com March 10, 2011

March 10, 2011

Status: Accepted Owner: siguc...(a)gmail.com New issue 3802 by siguc...(a)gmail.com: A strange superclasses if Canvas http://code.google.com/p/pharo/issues/detail?id=3802 Imagine that you can do something like: Object new drawOnCanvas: World assuredCanvas no, don't imagine. You can do that! :) At least it is supposed to work, because Canvas inherits from some strange things (NullEncoder, FlattenEncoder), so you can actually instruct any object to draw itself on canvas.. which is makes some sense (sort of): Canvas>>draw: anObject ^anObject drawOn: self Object>>drawOnCanvas:aStream self flattenOnStream:aStream. But as to me, Object should NOT implement #drawOnCanvas:, nor #drawOn:. Period. The real users of protocols placed in NullEncoder and FlattenEncoder is PostscriptCanvas which are not included into core images. So, the proposal is to remove the extra noise by making Canvas to be the subclass of Object. And for things which do care about serializing drawing commands onto some stream (like PostScriptCanvas do), make a subclass and introduce this behavior later.

[Pharo-project] Slides and Code | Networking @ Deep Into Smalltalk Spring School
by Noury Bouraqadi March 9, 2011

March 9, 2011

Hi, The slides and the Pharo code (with class comments :-) of my talk at the "Deep Into Smalltalk" Spring School are available at http://car.mines-douai.fr/noury/docs. The provided code covers the last two coding challenges of my talk: â¢ Simple TCP server implementing a basic Twitter-like server. I show how to use Socket for handling client connections and SocketStream to deal with data exchange with a client. â¢ Remote Messaging. The idea is to illustrate how to build a middleware similar to Remote Smtalltalk (rST) allowing message sends between objects located in different images. On the client side I show how to build a proxy, that is a place holder for a remote object. The proxy captures received messages and serialize them before sending the resulting bytes through a socket stream connected to the server. On the server side, a dispatcher recreates messages from received bytes and send them to the appropriate local object.
