>Hello - can my address please be removed from the Pharo mail list. I >will likely rejoin later, but for now I am receiving too many emails per >day from the list. Greatly appreciated, cheers, Josh Panar You do not have to unsubscribe to stop getting all these mails. Just go to http://lists.pharo.org/mailman/listinfo/pharo-users_lists.pharo.org and login. In the mailinglist settings you can deselect receiving mails. You can also choose to get a weekly summary if I remember correctly. The way I do it: I first subscribe, then disable the mail receiving and use the archive http://lists.pharo.org to go through the topics I'm interested. As one is still subscribed one can still post to the list but does not get all the mail traffic in the inbox. Works fine! Bye T.

dirty packages
by Usman Bhatti Jan. 28, 2015

Jan. 28, 2015

Hello, I have two packages MyPackage and MyPackage-Ext. When I load MyPackge-Ext, MyPackage becomes dirty and do not have any clue why. When I try to see changes in MyPackage in Monticello Browser, the package becomes clean again. There are two possibilities why MyPackage-Ext makes MyPackage dirty: -> There are names conflict of some sort (MyPackage-Ext can be seen as a category for MyPackage). -> Overriding of the extension methods introduced on the third package. Now I wrote a small script to verify it: firstCollection := (RPackage organizer packageNamed: 'MyPackage') extensionMethods values flatten. secondCollection := (RPackage organizer packageNamed: 'MyPackage-Ext') extensionMethods values flatten. (secondCollection intersection: firstCollection) The above script gives empty result so there are no overriding selectors. Any ideas how can I hack into Monticello to see what is causing MyPackage to become dirty while I load the second one manually. May be by logging the override load definitions on Transcript? In general, will it be possible to see overriding without these disappearing when doing changes on a dirty package? tx in advance. Usman

Pharo Sound of Silence
by Evan Donahue Jan. 28, 2015

Jan. 28, 2015

Hello, I'm trying to get sounds working in Pharo and I seem to be unable to locate a combination of PharoExtras/Sound and image/vm version that add up to audible sound. The best I've done so far is pharo3/sound6.1, which lets me beep, and write sounds to wav files, but the primitive for playing sounds fails silently. The pharo4/sound6 combination seems not to have a SoundService object that Beeper depends on, so I don't even get beeps. If anyone could help me figure out which version of what code is best supported right now, or why the sound playing primitive is failing, it would be most appreciated. Thank you, Evan

Building 3D shapes in Roassal with interaction. Unexpected behaviour?
by Nicolas Lusa Jan. 28, 2015

Jan. 28, 2015

Hello everyone, It has been a while since I started working with Woden and Roassal and I recently figured out that something is behaving unexpectedly (at least from my point of view). Assume we create 3 shapes (all the same kind) with Roassal (i.e. 3 RWPyramid) and we associate an eventListener to see when someone click on the object. In such case we change the color of the shape. Here is the code: v := RWView new. e := (RWPyramid new) element. e on: RWMouseButtonDown do: [ :ev | ev element shape color: WDColor blue. ev element changed. ]. v add: e. g := (RWPyramid new) element. g on: RWMouseButtonDown do: [ :ev | ev element shape color: WDColor green. ev element changed. ]. g translateBy:(WDVector3 newX: 4.0 y: 0.0 z: 0.0). v add: g . f := (RWPyramid new) element. f on: RWMouseButtonDown do: [ :ev | ev element shape color: WDColor red. ev element changed. ]. f translateBy:(WDVector3 newX: 2.0 y: 0.0 z: 0.0). v add: f. v addInteraction: RWMouseKeyControl. v camera position: (WDVector3 x: 0.0 y: 0.0 z: 3.0). v open. So far, so good. But now, let's try to change some objects type, (i.e. let's put a Pyramid a Cube and a Cylinder). Here is the code: v := RWView new. e := (RWPyramid new) element. e on: RWMouseButtonDown do: [ :ev | ev element shape color: WDColor blue. ev element changed. ]. v add: e. g := (RWCube new) element. g on: RWMouseButtonDown do: [ :ev | ev element shape color: WDColor green. ev element changed. ]. g translateBy:(WDVector3 newX: 4.0 y: 0.0 z: 0.0). v add: g . f := (RWCylinder new) element. f on: RWMouseButtonDown do: [ :ev | ev element shape color: WDColor red. ev element changed. ]. f translateBy:(WDVector3 newX: 2.0 y: 0.0 z: 0.0). v add: f. v addInteraction: RWMouseKeyControl. v camera position: (WDVector3 x: 0.0 y: 0.0 z: 3.0). v open. Now if you try this, and you'll try to click on the Pyramid, you will see that the cube is the one that gets to change color but not the Pyramid. Same if you click on the Cylinder. I think the code that I wrote is correct, but I might be wrong. Does anyone know what is the problem due? Cheers, Nicolas

Compatibility of Cypress, FileTree, STIG ?
by Damien Pollet Jan. 28, 2015

Jan. 28, 2015

Hi all, I'm trying to exchange code between VW and Pharo, but STIG does not seem to generate the same properties, and puts comment at the start of method files instead of the method category name, which confuses FileTree on the Pharo end. Any suggestions? -- Damien Pollet type less, do more [ | ] http://people.untyped.org/damien.pollet
