Reef: Initialization with default parameters
by Thomas Heniart May 15, 2015

May 15, 2015

Hi, Currently, I am playing with Reef and it is a cool framework but I have a little problem... I want to initialize a REForm with a parameter I need in initializeContents So I have something but it doesn't seem to be the right way... WAMyObject>>renderContentOn: html html render: (myReefForm new param1: self paramNeed) But during initialization of myReefForm, initializeContents is called before param1 initialization... If someone know what I should do :) An other question : Where can I find documentations on Reef ? The only things I have found are on http://smallworks.eu/web/projects/reef Cheers, Thomas

Transcript needs your love
by stepharo May 15, 2015

May 15, 2015

Hi guys the Transcript in Pharo is that it's not asynchronous so I can't use it in VM development to show the current progress of the simulation. For example: 1 to: 100 do: [ :i | 0.1 seconds asDelay wait. Transcript show: 'x'. ] => on Squeak, this shows a x every 0.1 second in the Transcript => on Pharo, nothing happens during 10 seconds then all the x are shown. https://pharo.fogbugz.com/default.asp?15515

OLEDB versus ODBC
by Ben Coman May 15, 2015

May 15, 2015

I hust bumped into some old news (2011) I hadn't heard before that I thought might be of interest to those working on database drivers for Pharo, to perhaps not spend any time on OLEDB. "Microsoft announced it will focus on supporting the Open Database Connectivity (ODBC) approach for SQL Server application programming interfaces (APIs) in the near future. Microsoft indicated that it will gradually step away from supporting OLE DB." https://redmondmag.com/articles/2011/09/01/microsoft-shifting-to-open-datab… cheers -ben

Re: [Pharo-dev] [squeak-dev] Cog VM problem?
by Eliot Miranda May 15, 2015

May 15, 2015

Hi Raymond, yes, thanks. We have a regression in the code generator due to recent changes to #== compilation. We're working on it. I hope to have a fix soon. Apologies for the inconvenience. For those of you curious why this only affects the V3 VM, not the Spur VM, the reason is that in Spur the Cogit passes up to 2 argument sends in registers but in V3 it passes only up to 1 arg sends in registers. In (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] ifFalse: [(BorderStyle perform: borderColor) width: borderWidth "argh."]. self setProperty: #borderStyle toValue: style]. #simple erroneously ends up getting spilled to the stack, so that when the send of width:color: to BorderStyle occurs the code generator emits code to access what it thinks is BorderWidth, but ends up accessing #simple instead. As I say we're working on it and should have a fix soon.

Re: [Pharo-dev] Trying to use Rubric in Nautilus ....

thanks Alain You rock :) When you visit us I would love to see if we could brainstorm on changs in Nautilus to remove the need for RubPluggable :) I would like to remove PluggableTextWithLimits and I would love also to deprecate TextMorph. Stef

Re: [Pharo-dev] Trying to use Rubric in Nautilus ....

Hi alain thanks a lot! This helps us a lot. We got nearly something working. We will produce a list of methods and changes we had to do. see in the attached cs. Now lookupMenu "default implementation of the algorithm that lookup the menu" | default | default := [ self editingMode menu ]. ^ self model ifNil: [ default value ] ifNotNil: [ :m | m menu ifNil: [ default value ] ] We add a new method in nautilus that creates a menu as follow because m is our NautilusModel menu ^ self sourceCodeMenu: MenuMorph new shifted: false. But I was wondering why m menu does not take into account the information we passed when we created the rubPluggable sourceTextArea := self textMorphClass on: self text: #sourceCodeFrom: accept: #compileSource:notifying: readSelection: #contentsSelectionFrom: menu: #sourceCodeMenu:shifted:. I see that RubEditingArea has a policy but we could find how we can improve RubPluggable to use the menu: To: pharo-dev(a)lists.pharo.org From: pharo-dev(a)lists.pharo.org CC: alain.plantec(a)yahoo.com Subject: Re: [Pharo-dev] Trying to use Rubric in Nautilus ....

(UIManager default newAutoAcceptTextEntryFor: self get: #selector set: #selector: class: String getEnabled: #haveClassName help: 'Enter a selector' translated entryCompletion: entryCompletion) acceptOnCR: false; ghostText: 'Selector'; withDropListButton; I think this is only for the drop down list. What I meant is that I could use set: and pass the selector to be invoked by the dropdown when the drop down is selected. And it will notify self with the selector: selector. So we could sepcify any selector (ie I can register to the drop box and say call me once you are set). In RubMethodEditingExample>>#selector: it calls the update explicit self updateCodeWith: (cls sourceCodeAt: selector) and updateCodeWith: sets the text on the text model. Now my problem (and may be there is not solution) is how can I connect from a pluggableListMorph to a RubScrollText when the list does not generate announcement. This is why I tried to pass via dependents or something like that. I will try to generate announcements but this is a lot more work and I do not know if it will work. Stef

Installing trait blow the method def in hierarchy
by Yuriy Tymchuk May 14, 2015

May 14, 2015

Hi, Iâve noticed that if you install a trait on a class and a trait defines explicit requirement method, and this method is defined in a super class, it is being looked up during execution through #explicitRequirement method. It was slowing down my execution by almost 20%. Is there a special way to use a Trait to avoid that, or itâs work-in-progress solution? Uko
