BitField
by abdelghani ALIDRA Nov. 19, 2015

Nov. 19, 2015

Hi everybody, I was discussing with Thibault about the performance of some methods defined on sets ( actually quite slow for big collections, mainly union: and intersection: ) and we were wondering if there is any implementation of some BitField-like class to speed up these operations? May be in an external project?Â Abdelghani

Array : very weird behavior
by abdelghani ALIDRA Nov. 19, 2015

Nov. 19, 2015

Hi everybody, I am experiencing a very weird behavior with Arrays : I writed a test case as follows ; testChange | bitArray1 | bitArray1 := #(0 0 0 0). (1 to: bitArray1 size) do: [ :index ||temp| temp := (bitArray1 at: index) + 1. bitArray1 at: index put: (temp). ]. self assert: bitArray1 = #(1 1 1 1) The thing is that the test succedes the first time but if I run it again it fails.Moreover, if Â I change theÂ testChangeÂ arbitrarily (just add a space and save) the test succeeds the first time then it fails.....etc. ActuallyÂ bitArray1 := #(0 0 0 0)Â changes the value of bitArray1 in the first run but then bitArray1 does not change any more in the next runs. The problem does not occur if Â I replaceÂ bitArray1 := #(0 0 0 0). withÂ bitArray1 := Array new:4 withAll: 0 . Any idea where the problem can be?Should I open a bug entry? where? Abdelghani

More fun with Morphic: 1st iteration of a Mindmapping tool
by Stephan Eggermont Nov. 19, 2015

Nov. 19, 2015

The past three days, Noah Domingo (15) and I have been working on a new Morphic example. We have build a first iteration of a Mindmapping tool. Noah shows it in: https://vimeo.com/136943448 We would be interested in some design critique. The way the Rubric text field is embedded in the MindmapNode is not so clean. The code can be loaded by Gofer it smalltalkhubUser: 'StephanEggermont' project: 'Mindmap'; package: 'Mindmap'; load

Direct messaging using Slack
by Alexandre Bergel Nov. 19, 2015

Nov. 19, 2015

Hi! In case you are not aware of it, a great number of the Pharo, Moose, and Roassal community members are on Slack. Slack is a very cool messaging platform. If you want to chat with developers and get instantaneous help on a topic, then Slack simply rocks. More info on: http://pharo.org/community Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

by Peter UhnÃ¡k Nov. 19, 2015

Nov. 19, 2015

Hi, do we have an editable droplist control? Something like html5 datalist https://developer.mozilla.org/en/docs/Web/HTML/Element/datalist where you can both select from a list of predefined values, or specify your own. Peter

Re: [Pharo-users] [Cuis] New Introductory Tutorial
by H. Hirzel Nov. 18, 2015

Hi Euan Worthwhile to refer to in your tutorial is as well the web version of the ProfStef Smalltalk tutorial implemented in Amber Smalltalk http://amber-smalltalk.github.io/trysmalltalk/ (https://github.com/amber-smalltalk/trysmalltalk) It explains the syntax, control constructs and some basic classes. It was first implemented in Pharo and then ported. --Hannes On 11/17/15, Juan Vuletich <juan(a)jvuletich.org> wrote: > Hi EuanM, > > This is a great initiative.

RewriteTool not working in latest Pharo
by Peter UhnÃ¡k Nov. 17, 2015

Nov. 17, 2015

Hi, RewriteTool is not working in latest pharo, complaining about #MNU CheckboxMorph>>hShrinkWrap when opening RewriteRuleBrowser, and #MNU LabelMorph>>hShrinkWrap for RewriteRuleBuilder. I am not familiar with Morphic enough and I don't know why the morphs are accessed directly from Spec to fix it... so I can only report it. :) Thanks, Peter

Multitouch example
by Stephan Eggermont Nov. 17, 2015

Nov. 17, 2015

I'm trying to get the multitouch example to work, connecting an iPad with TUIOPad to an MBP. Tuio2DDCirsor sends #deliverAdd:to:from: to an OSTUIODriver, that then tries to send #deliver:. That doesn't exist (anymore?). Anyone know what that's supposed to be now? Stephan
