[Pharo-project] About the scope of classVariables
by StÃ©phane Ducasse Oct. 7, 2011

Oct. 7, 2011

Hi guys I do not understand why classVariables cannot shadow globals and take precedence over them. When I define a classVariable the resolution should take classVariable over global. Right now I have to prefix my classVariable to be able to define them. Now what will happen if I define classVariable with a name that is ok in my current image but will be present in the future in the image I will load my code! I have to check what paolo did in GNU because he changed something. I think that there is something really broken or I'm totally stupid. Stef

[Pharo-project] One Liners to Impress Your Friends
by Sven Van Caekenberghe Oct. 6, 2011

Oct. 6, 2011

After reading these two post 10 CoffeeScript One Liners to Impress Your Friends http://ricardo.cc/2011/06/02/10-CoffeeScript-One-Liners-to-Impress-Your-Fri… 10 Scala One Liners to Impress Your Friends http://solog.co/scala/10-scala-one-liners-to-impress-your-friends.html I could not help but think why people get so excited about new languages while Smalltalk can and has been doing this for decades. So here are Smalltalk versions of their code (not that the examples are all that impressive): "--- 1. Multiple Each Item in a List by 2 ---" (1 to: 10) collect: [ :each | each * 2 ] "--- 2. Sum a List of Numbers ---" (1 to: 1000) inject: 0 into: [ :sum :each | sum + each ] (1 to: 1000) fold: [ :x :y | x + y ] (1 to: 1000) reduce: [ :x :y | x + y ] (1 to: 1000) sum "--- 3. Verify if Exists in a String ---" | wordList tweet | wordList := #( 'Smalltalk' 'Object-Oriented' 'REST' 'TDD' 'Play Framework' ). tweet := 'This is an example tweet talking about Smalltalk and TDD'. wordList anySatisfy: [ :each | tweet includesSubString: each ] "--- 4. Read in a File ---" (FileStream fileNamed: 'data.txt') contentsOfEntireFile "--- 5. Happy Birthday ---" 1 to: 4 do: [ :each | Transcript crShow: 'Happy Birthday ', (each = 3 ifTrue: [ 'dear Mr. President' ] ifFalse: [ 'to You' ]) ] "--- 6. Filter list of numbers ---" | passed failed | passed := OrderedCollection new. failed := OrderedCollection new. #(49 58 76 82 88 90) do: [ :each | (each > 60 ifTrue: [ passed ] ifFalse: [ failed ] ) add: each ]. { passed. failed } #(49 58 76 82 88 90) groupedBy: [ :each | each > 60 ] "--- 7. Fetch and Parse an XML or JSON web service ---" XMLDOMParser parse: (ZnNeoClient new get: 'http://search.twitter.com/search.atom?&q=pharoproject') JSJsonParser parse: (ZnNeoClient new get: 'http://search.twitter.com/search.json?&q=pharoproject') "--- 8. Find minimum (or maximum) in a List ---" #(14 35 -7 46 98) fold: [ :x :y | x min: y ] #(14 35 -7 46 98) min #(14 35 -7 46 98) fold: [ :x :y | x max: y ] #(14 35 -7 46 98) max "--- 9. Parallel Processing ---" "No such standard support, but multithreading is of course available" "--- 10. Sieve of Eratosthenes ---" "Unreadable code is not a good idea, this is longer but readable" | primes | primes := Array new: 100 withAll: true. primes at: 1 put: false. 2 to: primes size sqrt ceiling do: [ :each | (primes at: each) ifTrue: [ each * 2 to: primes size by: each do: [ :eachMultiple | primes at: eachMultiple put: false ] ] ]. OrderedCollection streamContents: [ :stream | primes doWithIndex: [ :each :index | each ifTrue: [ stream nextPut: index ] ] ] Maybe we could turn this into a blog post after some discussion ? To really show off Smalltalk, we might need a couple more impressive examples. Sven

[Pharo-project] Getting and loading each version of a package? (Gofer?)
by Mariano Martinez Peck Oct. 6, 2011

Oct. 6, 2011

Hi guys. I could try to find it myself but I am sure I will spend a lot of time and you may be able to help me. In summary, I want a script (possible with Gofer) that can iterate and load from Fuel package version XXX to YYY, fetching and loading each of the existing version between XXX and YYY and let me executing something for each of the version. Is that possible? Thanks a lot in advance, -- Mariano http://marianopeck.wordpress.com

by Marcus Denker Oct. 6, 2011

Oct. 6, 2011

Hi, We are slowly, but steadily uploading videos to Youtube. http://www.youtube.com/user/esugboard There are now 50 videos already. The idea is to upload all videos we have from 2008, 2009, 2010 and 2011. In addition, the "Deep into Smalltalk" tutorials. If you want to be notified about single uploads, there are multiple possibilities: - subscribe to Youtube, turn on email notification. This way you get title, screnshot and the Abstract via mail of every video uploaded. - subscribe to http://twitter.com/#!/esugsmalltalk Youtube sends a tweet automatically for every upload. (Please retweet the ones you like!) Marcus -- Marcus Denker -- http://marcusdenker.de
