Re: [Pharo-users] Woden - Rotate an Object from absolute referential
Hello Merwan, Currently is not possible because the only way to represent rotations is to use a matrix. I have to add support for quaternions, which gives me an opportunity to also add Euler angles. When I add support for Euler angles, you wil be able to do what you want easily. Currently, you have to use node orientation: (WDMatrix3 xrot: angle) to achieve what you are trying to do. Greetings, Ronie 2015-05-04 11:55 GMT-03:00 merwanoudd...@gmail.com: Hello everyone, I am currently making a little demo with woden and I would like to rotate a cube, not from the relative referential but from the absolute one ( rotate X always rotate in the same direction even if I previously have rotated Y ). What currently happens is that when I rotate the cube, the referential rotates as well... Does anyone know how to counter this ? Thanks Merwan

Does this mean that on Linux I just can't ? Mathieu contact Merwan to see if he has support for that. That is correct by default, but you can always hack the VM if you rally want that behavior. Also, if you just wait a bit, I'm in the process of remapping the wheel simulation shortcuts to be extremely less likely to conflict with actual keyboard events. It is already done for Mac. I wrote the patch for GNU/Linux Windows, but didn't have machines available when I was testing (the code may take a bit of massaging to compile). The upside is that it's a backward compatible VM change, so you will be able to take advantage of it in any Pharo version that will run on the latest VMs. Matthieu Lacaton wrote And does this mean that if I create an application able to react to mouse wheel, I need to code it differently for Windows and for Linux ? No, you would code it the same way. In the image, MouseWheelEvents are created regardless of the keyboard event used to simulate them. The only thing different would be the keyboard equivalents.
[Pharo-users] beginner question - how to get a fully qualified filename from a dialog
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
objectmethod, I'd appreciate that as well.)

Re: [Pharo-users] beginner question - how to get a fully qualified filename from a dialog
Hi,
maybe instead of UIManager you could look on UITheme.
For example the following code:
Smalltalk ui theme
chooseFullFileNameIn: World
title: 'Select file to open'
extensions: nil
path:
(myActualFilePath isNil
ifTrue: [ myActualFilePath ]
ifFalse: [ FileSystem workingDirectory ])
preview: nil
This will open a dialog with Select file to open in title, it will
accept file of every extension and the path will begin at
myActualFilePath or into the working directory if the actual file path
is nil.

Re: [Pharo-users] Using VirtualGPU
Hi Serge, I made some experiments with GPU computing with JavaScript. I understood that the computings are made forever inside the GPU, so you just throw data and programs once and you let the GPU compute for you. Yet the problem is to read the data once they are computed. With webGL it seems impossible, with webCL it is possible and not easy. Hence the choice of openCL I guess. I relate here how I could compute the powers of a Markov matrix here: http://revue.sesamath.net/spip.php?article651 (especially click on webGL sans three.js). I also made some experiments here: http://irem.univ-reunion.fr/spip.php?article797 (but they use three.js if I remember well) Happy readings, and, yes, I feel interersted in these subjects Alain On Tue, May 12, 2015 at 7:48 PM, Serge Stinckwich serge.stinckw...@gmail.com wrote: Dear all, just to let you know, Cheikhou (in CC) is starting a student internship in my lab.

[Pharo-users] Garage and SQLite file databases, general project structure
Hi Guille, I had a short look at Garage [1]. Nice initiative! Looks like using a file is not supported for the SQLite3 backend in Garage: GADriver fromConnectionString: 'sqlite3://file://C:/temp/test.db' GADriver fromConnectionString: 'sqlite3://C:/temp/test.db' Maybe GASqlite3DriverfromConnectionString: could be adopted, but the conversion to a Zn URL already removes some stuff. (Ab)using the schema in the URL as a driverID is nice - but prevents the use of file:// schema. How can one construct a file db? Also I do not understand: while Garage-Postgres uses the Postgres project PostgresV2 as a backend the Garage-Sqlite3 does not use NBSqlite3 or SQlite3 projects as backend. So GASqlite3FFI copies many methods of the original NBSQLite3 project from Pierce and myself and is therefore like an own fork now. Also the name FFI is misleading as it uses NativeBoost instead of FFI ... Also it would be good if the project would be layered, we could have a Garage-Core and Garage-Tests-Core with Garage-Mysql and Garage-Tests-Mysql for the fixtures. The idea is always to be able to load runtime code without tests for production code. Thanks Torsten [1] http://lists.pharo.org/pipermail/pharo-users_lists.pharo.org/2015-May/019192.html

[Pharo-users] Enhancing ICal library
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).

Re: [Pharo-users] Image growing size
I am using TWM and yes it gobbles memory. Disable/GC/Enable is indeed aomething do every once in a while. No need for snapshots for this to occur. A couple of Nautilus windows do the same. Youcan close them all in TWM and still have them eat memory.

Is this normal or have i done something wrong? I haven't been using globals, just downloaded and defined some packages. The only over persistent thing i've done is to keep an instance variable in some classes i wanted to have a unique instance. Best, Laura
[Pharo-users] Moving the HandMorph
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
[Pharo-users] Using VirtualGPU
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 (Stéphane ?) 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/

Re: [Pharo-users] Moving the HandMorph
A bit extreme, but you could open World Tools Process Browser and notice Input Event Fetcher then put a self haltOnce in InputEventFetchersignalEvent: 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.laca...@gmail.com wrote: Hello everybody, Is there a way to move the position of the cursor (the HandMorph) by passing commands to it ?

Re: [Pharo-users] Moving the HandMorph
Okay. That was 2 years ago so I was wondering if something had changed since then but apparently not.
