Pillar vs Pandoc?
by Alexandre Bergel April 6, 2016

April 6, 2016

Hi! Offray is visiting us in Chile. He showed me http://pandoc.org and it seems to be pretty cool. Looks like a strong competitor. I am wondering how Pillar position itself against Pandoc?

Philosophy here
by Igor Stasenko April 5, 2016

April 5, 2016

(This philosophical post provoked by discussion in another thread where we talking about cases of implementing wrappers and layers of composition.) To achieve more you shall do more. Usual truth thing in daily life. Not so true for programming. It actually 'do less to achieve more'. Because it's non-linear in programming. Because each line of code you add to the system is increasing it complexity accordingly. And that means more effort for future maintenance for you, or for some other unsuspecting victim. So, that's why i always look how to do less, reduce the amount of code, to achieve something. But not just plainly implement yet another feature, so its done. -- Best regards, Igor Stasenko.

[bloc] shape size?
by stepharo April 4, 2016

April 4, 2016

Hi I want a square morph with a circle or a line at 45 degree inside Now I do not get it. I thought that I needed to specialize drawOnAthensCanvas: so I did BlCell >> drawOnAthensCanvas: aCanvas super drawOnAthensCanvas: aCanvas. aCanvas drawShape: (BlShape new strokePaint: (BlStrokePaint new paint: (BlColorPaint new color: (Color blue)); width: 15); path: BlCirclePath new). Now I do not know how I can specify a shape size So I will use another API than drawShape: Stef

[Ann] New version of Ghost
by Denis Kudriashov April 4, 2016

April 4, 2016

Hello. I finished new version of Ghost: - DNU approach for basic proxies instead of #cannotInterpret: trick (trick used only for class proxies) - Abstract proxy classes uses Ghost name instead of Proxy: there are GHObjectGhost and GHClassGhost. - GHProxyHandler renamed to GHGhostBehaviour. Concrete ghosts should implement #ghostBehaviour instead of #proxyHandler. - GHGhostBehaviour should define #currentMetaLevel to specify set of messages which should not be intercepted. Such meta messages will be executed under ghost instance by subclass of GHMetaMessages. In previous version there was dictionary which maps meta message selector to implementation selector. It was not suitable. Now meta messages should be directly implemented on particular GHMetaMessages subclass and all it methods are considered meta. So GhostBehaviour should return instance of GHMetaLevel with meta messages implementation class: - GHMetaLevel with: GHEmptyMetaMessages "when all possible messages should intercepted" - GHMetaLevel with: GHStandartMetaMessages "when tools specific messages should not be intercepted" For example standard meta messages implements #inspect: GHStandartMetaMessages>>inspect "Create and schedule an Inspector in which the user can examine the receiver's variables." ^ Smalltalk tools inspector inspect: *ghost* - Traits for methods explicitly defined on ghosts: TMinimalProxy, TNotNilProxy, TIdentifiedProxy (with #=, #hash, #class). Concrete proxies can add this traits to itself independently from meta level. For example traits supply convenient methods to retrieve ghost information in polymorphic way with objects: - ghost isGhost - ghost ghostClass "returns actual class of receiver" - ghost ghostPrintString "returns string which represents ghost from meta level point of view" This traits are suitable and they provide some kind of optimisation for proxies (methods from traits are executed directly instead of complex meta messages mechanizm). But maybe they are superfluous. For example they can't be reused for class proxies which substitute real object classes (to intercept all instance messages). - GHClassGhost able to replace class of real objects. It implements cannotInterpret: trick to intercept all instance messages. Subclasses should define two behaviours: #ghostBehaviour (as any other ghost) and #instancesBehaviour which will process instance messages. In previous version it was different message to same #ghostBehaviour. - New kind of proxies: - GHObjectVirus. It is special kind of GHClassProxy. It infects real object to intercept it messages. From meta level infected object looks like healthy object which means that meta messages are executed by infected object itself. As class virus looks like real victim class. So in case when virus is created with standard meta level tools will not differ him from health object. There are special messages which allow ask object about viruses: - infectedObject isInfectedByVirus - infectedObject virus - infectedObject recoverFromVirus - GHLearningObject. It is suitable proxy which retrieves all unknown methods from teacher class. Thank's Stephan for this idea. This kind of proxy allows me easily find required set of messages to support inspectors and debuggers. You can create instance of learning object by: GHLearningObject withTeacher: Object. And any operation with it will fill studiedMessages dictionary. In my case I opened GTInspector on it and got all messages which was needed for him. - Ghosts works correctly with latest Pharo 5 tools (basic inspector, GTInspector, SpecDebugger, GTDebugger). Required methods for tools are extracted to 'Ghost-GTSupport' package. - Repackaging: - Ghost-ObjectProxies. It contains all core classes and abstract GHObjectGhost which is based on DNU - Ghost-ClassProxies. It contains code for proxy which can substitute class of real object. GHClassGhost implements cannotInterpret: trick to intercept all instance messages. And it implement support for debugging such methods. - Ghost-LearningObject - Ghost-ObjectVirus - Ghost-GTSupport - test packages - All code moved to Pharo repository http://smalltalkhub.com/#!/~Pharo/Ghost (in includes packages from CAR repo too) You can load new version by: Gofer it smalltalkhubUser: 'Pharo' project: 'Ghost'; configurationOf: 'Ghost'; loadStable I use it now in Seamless and Mocketry.
