[Pharo-project] Spaktacualr Class Forest of Pharo
by HwaJong Oh June 8, 2011

June 8, 2011

Hi, I've http://appdal.com/groups/36442/wiki/56611/Pharo__.html rendered all the classes of Pharo into a forest of 3D space with http://appdal.com/groups/36442/wiki/47cf4/Pharo____.html Sketchup Ruby script which was generated by Pharo code. (it does not generate definition of ruby methods. You need to type it :-( ) You can get that code by using Gofer: Gofer new squeaksource: 'DaliotsPlayground'; package: 'ConfigurationOfSketchupRuby'; load. (Smalltalk at: #ConfigurationOfSketchupRuby) project latestVersion load.

[Pharo-project] support for flattening-out traits for export?
by Torsten Bergmann June 7, 2011

June 7, 2011

>Just a meta question..... What about real questions: - are Traits used these days - in which packages and why - how is the adoption rate I havent much used them by myself (mostly due to the lack of time to dig into it) but I would like to learn about the current state of Traits (is it used, maintained, usable). And yes - we can add lots of (language) features. But we should also discuss/measure/find out if they are usefull. Some of them help us moving forward others may stand in our way. And "Keep it simple" is always a good rule ... One great thing in languages like Smalltalk is that you can care about the problem ... and not so much about satisfying the compiler or knowing about the 10 most recent language features nailed to the language to circumvent problems from early language design. I think we should be more serious ... Marianos may have some valid points we should discuss. So let him tell us why he avoided Traits and what are the issues with tools. Let's listen and learn. >"he last time something serious was new in Smalltalk it was back in 1984" >"got killed by Java" >"Pharo is not about maintaining the past." Sorry Stef, but to me these are phrases and not releated to the question about the usefullness of Traits. Language features were not the reasons why Java took up. Back at the time it was small, free, multiplatform and available in the web (applets) when the web took up and no radical change for most programmers. In fact languages features are discussed these days for Java and we should discuss them too... Especially since Smalltalk is not a programming language ... more a dynamic object system on top of a VM with a language built in. Which path would we like to take with Pharo? Adding more language features to be comparable to other languages? Or even become a multilanguage platform/embed new languages similar to JVM and .NET VM (maybe with Helvetia)? What are our goals here? Bye T. -- NEU: FreePhone - kostenlos mobil telefonieren! Jetzt informieren: http://www.gmx.net/de/go/freephone

Hi guys with ben we changed ((value isKindOf: Class) and: [ key == value name ]) into fillCaches "Fill cachedClassNames and cachedNonClassNames. Return an array with the calculated values." | classNames nonClassNames | classNames := OrderedCollection new: self size. nonClassNames := OrderedCollection new. self keysAndValuesDo: [ :key :value | "The key == value name test below addresses two separate issues: 1) Obsolete classes, where key = #Foo and value name = 'AnObsoleteFoo' 2) Aliases, i.e., Smalltalk at: #OtherName put: aClass" ((value isKindOf: Class) and: [ key == value name ]) ifTrue: [ classNames add: key ] ifFalse: [ nonClassNames add: key ] ]. classNames sort. cachedNonClassNames := nonClassNames sort. cachedClassNames := classNames. ^{ classNames. nonClassNames } by ((value isKindOf: (self at: #Class)) and: [ key == value name ]) and this is not a good change because it assumes that an environment has a class Class and it jumps over the fix point created by the compiled time binding to Class. Now we did that because in Hazel we build a new kernel and the new environment needs to have its own Class class. Now I have the impression that ((value isKindOf: (self environment at: #Class)) and: [ key == value name ]) is the solution since HSystemDictionary which should be defined in itself could work Now if somebody has a better idea, I'm all ears (esepcially sincewe do not have a nice object to dispatch on). stef

The same way we build a DBX driver for Glorp, we created a PostgreSQL one with what we removed with the hardcoded stuff in SqueakDatabaseAccessor. Such code from the previous versions of GlorpDBX was in http://www.squeaksource.com/PostgresV2 package GlorpDriverPostgreSQL We will give it a try and let you know if it is working. > _______________________________________________ > SqueakDBX mailing list > SqueakDBX(a)lists.squeakfoundation.org > http://lists.squeakfoundation.org/mailman/listinfo/squeakdbx > -- Mariano http://marianopeck.wordpress.com
