beginner question - how to get a fully qualified filename from a dialog

by amaloney

I have a method: openSimulationFile inFile := (StandardFileStream fileNamed: '/Users/amaloney/Squeak/30shoes.txt') ascii I want to replace the hard coded fully qualified filename with the result of a file browser dialog. I've done some Googling and poked around in the system browser and I find that if I enter (in a playground) UIManager default chooseDirectory and inspect-it I get: a FileReference (/Users/amaloney/Squeak) and if I try UIManager default chooseFileMatching: #( '*.txt' ) I get: a ByteString ('Readme.txt'). It seems that UIManager chooseDirectory is the method I should start exploring (since it returns a FileReference object) but the method is: chooseDirectory "Let the user choose a directory" ^self chooseDirectoryFrom: FileSystem workingDirectory and when I look at chooseDirectoryFrom: I get chooseDirectoryFrom: dir "Let the user choose a directory" ^self chooseDirectory: nil from: dir so I look at chooseDirectory: from: and I get: chooseDirectory: label from: dir "Let the user choose a directory" ^self subclassResponsibility Which doesn't help so I dig around in the docs some more and find out that the green down arrow is clickable. When I click it and choose MorphicUlManager>>#chooseDirectory:from: the method definition is: chooseDirectory: label from: dir "Answer the user choice of a directory." | modalMorph realLabel | realLabel := label ifNil: ['Choose Directory' translated]. (ProvideAnswerNotification signal: realLabel) ifNotNil: [:answer | ^answer ]. modalMorph := self modalMorph. ^modalMorph theme chooseDirectoryIn: modalMorph title: realLabel path: (dir ifNotNil: [dir fullName]) The problem is that I cannot find a chooseDirectoryIn:title:path: method. I wrote this all out hoping someone can tell me where I chose the wrong rabbit hole and can point me to instructions on how to choose the correct rabbit hole. ;-) (Also, if there is a short answer i.e. use this object>>method, I'd appreciate that as well.)

Okay. That was 2 years ago so I was wondering if something had changed since then but apparently not.

Re: [Pharo-users] Moving the HandMorph

by Ben Coman

A bit extreme, but you could open World >> Tools >> Process Browser and notice "Input Event Fetcher" then put a "self haltOnce" in InputEventFetcher>>signalEvent: and trace through. Or maybe have a look at HandMorphForReplay in http://forum.world.st/ANN-EventRecorderMorph-Port-to-3-0-td4736258.html (disclaimer, I haven't got around to having a look at this myself yet) cheers -ben On Tue, May 12, 2015 at 11:40 PM, Matthieu Lacaton < matthieu.lacaton(a)gmail.com> wrote: > Hello everybody, > > Is there a way to move the position of the cursor (the HandMorph) by > passing commands to it ? > > I tried things like "ActiveHand position:" or "ActiveHand moveToEvent:" > but nothing worked for me. > > Thanks, > > Matthieu >

Using VirtualGPU

by Serge Stinckwich

Dear all, just to let you know, Cheikhou (in CC) is starting a student internship in my lab. He will work on Epidemiology Modelling with KENDRICK: http://ummisco.github.io/kendrick/ the platform that we are developing in order to analyse and visualise diseases models behaviours. We would like first to implement a GPU version of the Gillespie Stochastic Simulation Algorithm (GSSA): http://en.wikipedia.org/wiki/Gillespie_algorithm and after that also implement SPH simulations: https://en.wikipedia.org/wiki/Smoothed-particle_hydrodynamics We are looking at the code of OpenCL and VirtualGPU done by Ronnie. What we have understand until now : - OpenCL package : low-level stuff to be able to interface OpenCL kernels with Pharo - VirtualGPU: high-level API on top of OpenCL in order to ease the task of people who wants to use OpenCL. VirtualGPU provide high-level operations on matrix and image at the moment. @Ronie: What is not clear at the moment in our mind : when you build a VirtualGPU program with the DSL, do you have the overhead of communications every time you execute a VirtualGPU instruction or all the the instructions are sent at the same time and run on the GPU ? In our context, for building a GSSA algorithm, I guess we just have to combine same VGPU instructions (matrix computations) but for doing SPH simulations, we will have to provide our own instructions. Is there any documentation in order to add own kernel and instructions ? I know that others guys at INRIA (StÃ©phane ?) are interested by GPU. Is it possible to join our effort to share what we are doing ? Regards, -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://www.doesnotunderstand.org/

Moving the HandMorph

by Matthieu Lacaton

Hello everybody, Is there a way to move the position of the cursor (the HandMorph) by passing commands to it ? I tried things like "ActiveHand position:" or "ActiveHand moveToEvent:" but nothing worked for me. Thanks, Matthieu

Enhancing ICal library

by Julien Delplanque

Hi everyone, I took a little time to enhance the ICal library and to make it work with Pharo 4! So I forked the one on smalltalkhub (http://smalltalkhub.com/#!/~pdebruic/iCal) and put all the modified code on github https://github.com/juliendelplanque/pharo-ical. Why did I forked? Well, I wanted to make it work on pharo 4 first, so I contacted the owner of the smalltalkhub repository. He wanted to keep it working on other smalltalk than Pharo. The problem was that the lib used Url class that were deprecated in Pharo 3 and even removed on Pharo 4! So I managed to repair the package using ZnUrl. Since I don't know if the owner of this lib on Smalltalkhub have time to manage the problem to keep the lib "multi-smalltalk", I have chosen to fork it so he can keep his version compatible. Good news are that I plan to keep it alive as long as I can, write some documentation for it when I have time and even try to enhance it. I already added a GTInspector extension to have better representation of iCalendar when inspecting them in Pharo. The version on master branch is supported by Pharo 2-3-4 (didn't check with Pharo 1). Regards, Julien

Re: [Pharo-users] Creating a Class in a Temporary Environment

by Camille

Hi Sean, You can use AnonymousClassInstaller instead of PharoClassInstaller. We should improve it because it has limitations: the environment is not used and you wonât be able to change the slots or the superclass after creation. AnonymousClassInstaller make: [ :builder | builder superclass: Object; name: #AClassForTesting ]. Camille > On 12 May 2015, at 12:45, Sean P.

Re: [Pharo-users] Creating a Class in a Temporary Environment

by Mariano Martinez Peck

Sean, Maybe it is not exactly what you asked but when it is about creating classes/traits for testing I always used ClassFactoryForTestCase (see it is used by Fuel). You can even check how that class currently creates the stuff. Cheers, On Tue, May 12, 2015 at 7:45 AM, Sean P.
