4.4 ready?
by Frank Shearar 01 Jan '13

01 Jan '13

Other than the fact that the last two builds for SqueakTrunk have hung - an issue I'm looking into, but wouldn't mind others trying their luck - are we happy enough with 4.4 that we'd want to ship it? My gut feel is (and with my Release Manager hat on), judging by the low severity of the few reports we're seeing, that we're there. What do others think? One thing we _don't_ have is an "All-in-one" one-click type installer for the various OSes. If someone can show me what to do, I can add a job to spit out such a thing. frank

Re: [Newbies] Two questions about Smalltalk language design

If it returns the last value in the expression: the following method would return the result from #doSomething; but to know what kind of object would be returned from it, you need to recursively look into many methods. method1: var1 var1 doSomething. Why not return something along the line of nil is.... It certainly is more useful to be able to chain messages for simple setters. > 2) In Collections, why does "add:" return the object being added, and > not "self"? > > http://stackoverflow.com/questions/14047940/why-does-add-return-the-object-… Smalltalk-72's "vector" had that semantics more or less, when assigning a new value to a slot. Check out "to vector" in http://ftp.squeak.org/goodies/Smalltalk-72/ALLDEFS I can see some reason for that semantics: One perhaps was that because assignment was just a message send to a quoted variable, and you can define its behavior based on the receiver. When the receiver is a quoted vector, your assignment can update a slot of it. In many languages (not in Scheme however), the value of the assignment is the value to be assigned so you can say: x := y := 0. So, it is convenient to make the value of such message to be the value to be assigned. Another is that it certainly is convenient to get back the removed element when you are removing an element from a collection. Making add: do the same makes it more symmetric. -- -- Yoshiki

I hope it's not too late for inclusion in 4.4 because this one is annoying...

Squeak Board blog annual report (from Wordpress)
by Chris Cunnington 30 Dec '12

30 Dec '12

http://squeakboard.wordpress.com/2012/annual-report/ This is sort of fun. Wordpress sent me a webpage annual report for the blog squeakboard.wordpress.com. It's quite visual. Some facts that stick out: 22 new posts in 2012; reddit.com is our second largest referrer; New Development Model is our second most read post; some people Google it with "chris cunnington squeak".

Xtreams question - OC of chars to String
by Chris Cunnington 30 Dec '12

30 Dec '12

I have a question about converting an OrderedCollection full of chars into a string. [1] I would have thought there was a method like #asString that could be sent to an OrderedCollection to produce a string. I find myself having to do the process in three steps: 1) #reading the OC; 2) creating an empty string; and then, 3) iterating over every char to put it into the String. I think I'm missing a simpler way. Especially with Xtreams. Shouldn't I just use a filter, change the #contentSpecies, or something? Chris [1] startTag: data <action: 'element'> |tagdata str | tagdata := data second first reading. str := (String new: 20) writing. tagdata do: [:each| str put: each]. ^'html ' , (data first second first asString) , $: , $' , (str close; terminal) , $'
