[Bug] ? Rotating a window via halo causes an exception
by Ariel Feinerman 21 May '15

21 May '15

Hi all, I try to rotate a window via halo but it causes an exception because Color object does not understand width: color message. How to fix it? As far as I remember in previos versions all worked. ------------------------------------------------------------------------------------------------------------------------------------------- borderStyle "Work around the borderWidth/borderColor pair" | style | borderColor ifNil: [^BorderStyle default]. borderWidth isZero ifTrue: [^BorderStyle default]. style := self valueOfProperty: #borderStyle ifAbsent: [BorderStyle default]. (borderWidth = style width and: ["Hah! Try understanding this..." borderColor == style style or: ["#raised/#inset etc" #simple == style style and: [borderColor = style color]]]) ifFalse: [style := borderColor isColor ifTrue: [BorderStyle width: borderWidth color: borderColor] " ----> this string causes an exception" ifFalse: [(BorderStyle perform: borderColor) width: borderWidth "argh."]. self setProperty: #borderStyle toValue: style]. ^style trackColorFrom: self

Dynamic Languages Symposium (DLS) 2015 | Call for Papers
by Robert Hirschfeld 20 May '15

20 May '15

----------------------------- C A L L F O R P A P E R S ----------------------------- ======== DLS 2015 =========== 11th Dynamic Languages Symposium 2015 October, 2015 Pittsburgh, Pennsylvania, United States http://DLS2015.inria.fr Co-located with SPLASH 2015 In association with ACM SIGPLAN The 11th Dynamic Languages Symposium (DLS) at SPLASH 2015 is the premier forum for researchers and practitioners to share knowledge and research on dynamic languages, their implementation, and applications. The influence of dynamic languages -- from Lisp to Smalltalk to Python to Javascript -- on real-world practice and research continues to grow. DLS 2015 invites high quality papers reporting original research, innovative contributions, or experience related to dynamic languages, their implementation, and applications. Accepted papers will be published in the ACM Digital Library, and freely available for 2 weeks before and after the event itself. Areas of interest include but are not limited to: Innovative language features and implementation techniques Development and platform support, tools Interesting applications Domain-oriented programming Very late binding, dynamic composition, and run-time adaptation Reflection and meta-programming Software evolution Language symbiosis and multi-paradigm languages Dynamic optimization Hardware support Experience reports and case studies Educational approaches and perspectives Semantics of dynamic languages == Invited Speaker == DLS is pleased to announce a talk by the following invited speaker: Eelco Visser: Declare your Language. == Submissions and proceedings == Submissions should not have been published previously nor under review at other events. Research papers should describe work that advances the current state of the art. Experience papers should be of broad interest and should describe insights gained from substantive practical applications. The program committee will evaluate each contributed paper based on its relevance, significance, clarity, length, and originality. Papers are to be submitted electronically at http://www.easychair.org/conferences?conf=dls15 in PDF format. Submissions must be in the ACM format (see http://www.sigplan.org/authorInformation.htm) and not exceed 12 pages. Authors are reminded that brevity is a virtue. DLS 2015 will run a two-phase reviewing process to help authors make their final papers the best that they can be. After the first round of reviews, papers will be rejected, conditionally accepted, or unconditionally accepted. Conditionally accepted papers will be given a list of issues raised by reviewers. Authors will then submit a revised version of the paper with a cover letter explaining how they have or why they have not addressed these issues. The reviewers will then consider the cover letter and revised paper and recommend final acceptance or rejection. Accepted papers will be published in the ACM Digital Library. Important dates Abstract Submissions: Sun 7 Jun 2015 Full Submissions: Sun 15 Jun 2015 First phase notification: Mon 27 Jul Revisions due: Mon 3 Aug Final notification: Mon 17 Aug Camera ready: Fri 21 21 Aug Program chair Manuel Serrano, Inria Sophia-Antipolis, dls15(a)easychair.org Program committee Carl Friedrich Bolz, DE William R.

[Tools] (Object >> #inspect) now returns the tool instead of the object
by marcel.taeumel 20 May '15

20 May '15

Hi, there! :) I just want to mention and explain, why (Object >> #inspect) now returns the tool window instead of the object as in 4.5. The Tools package adds several convenient methods to the base system: Object >> #explore Object >> #inspect Object >> #browse Behavior >> #browse All but #inspect returned the created tool. So I went for consistency. But in particular, those methods should return the tool because because otherwise the programmer has no simple means to access the created window/tool programmatically. Model and object are, however, always accessible (via #model or just #self). So if you got code like this: self someObjects add: myObject inspect. Please change it to: self someObjects add: myObject inspect; yourself. Or even better to: myObject inspect. self someObjects add: myObject. I think that it is good practice/style to use #yourself if you want to get the receiver back in a chain of calls: self myMorphs add: (MyMorph new color: Color yellow; yourself). Best, Marcel -- View this message in context: http://forum.world.st/Tools-Object-inspect-now-returns-the-tool-instead-of-… Sent from the Squeak - Dev mailing list archive at Nabble.com.

Deceptive focus cue in 4.6 browsers
by Stéphane Rollandin 20 May '15

20 May '15

Try this: - Disable the "Filterable Lists" preference. - Open a new Browser. - Choose any class - Select any message category You get a method template in the text pane. It is highlighted, which makes you think (and it was the behavior so far) that you can type right away your method code. But it is not the case. The message category list still has focus; moreover you need to click inside the code editor to give it focus, which deselect the method template. Annoying. Stef
