saving an image on windows and opening it on mac problems

by Andrei Chis

Hi all, I saw that there are a few issues about images saved on an operating system not working when opened on other operating systems: - https://pharo.fogbugz.com/f/cases/19852/Unable-to-open-image-in-OSX-after-i… - https://pharo.fogbugz.com/f/cases/19869/Infinite-loop-on-mac-when-opening-a… - https://pharo.fogbugz.com/f/cases/19272/Image-freezes-on-Linux-if-it-was-pr… - http://forum.world.st/Image-freezes-on-Linux-if-it-was-previously-saved-on-… I gave the fix in case 19869 a try and with it I can save an image on windows and open it on mac, however, there are some side effects. First several folders having the following name are created in the image folder: '\Users\andrei\test-image' '\Users\andrei\test-image\pharo-local\' '\Users\andrei\test-image\pharo-local\ombu-sessions' Second, I can only open the image on man once. The second time I get the following stack: [31mPrimitiveFailed: primitive #createDirectory: in WindowsStore failed [0mWindowsStore(Object)>>primitiveFailed: WindowsStore(Object)>>primitiveFailed WindowsStore(DiskStore)>>createDirectory: WindowsStore(FileSystemStore)>>ensureCreateDirectory: WindowsStore(FileSystemStore)>>ensureCreateDirectory: WindowsStore(FileSystemStore)>>ensureCreateDirectory: WindowsStore(FileSystemStore)>>ensureCreateDirectory: WindowsStore(FileSystemStore)>>ensureCreateDirectory: WindowsStore(FileSystemStore)>>ensureCreateDirectory: FileSystem>>ensureCreateDirectory: FileReference>>ensureCreateDirectory OmSessionStore>>resetWithStoreNamed: OmSessionStore>>resetWithNextStoreName OmSessionStore>>store WeakMessageSend>>value WeakMessageSend>>cull: WeakMessageSend>>cull:cull: [ action cull: arg1 cull: announcer ] in LegacyWeakSubscription(WeakAnnouncementSubscription)>>deliver: in Block: [ action cull: arg1 cull: announcer ] BlockClosure>>on:do: BlockClosure>>on:fork: LegacyWeakSubscription(WeakAnnouncementSubscription)>>deliver: [ tmp4 deliver: arg1 ] in SubscriptionRegistry>>deliver:to:startingAt: in Block: [ tmp4 deliver: arg1 ] BlockClosure>>ifCurtailed: SubscriptionRegistry>>deliver:to:startingAt: SubscriptionRegistry>>deliver:to: SubscriptionRegistry>>deliver: SystemAnnouncer(Announcer)>>announce: SystemAnnouncer>>announce: SystemAnnouncer>>snapshotDone: SessionManager>>snapshot:andQuit: [0m So it seems that OmSessionStore is not reset and holds a reference to a the windows path which it tries to create.

Re: [Pharo-dev] calling methods directly on traits

by Guillermo Polito

Hi, No, it's the same as in classes. If methods are on the instance side, you cannot call them unless you instantiate the class.

calling methods directly on traits

by Peter Uhnak

Hi, would it be possible to somehow call a method directly on a trait? e.g. Trait named: #TMyTrait. then add method TMyTrait>>twelve ^ 12 and then I could do `TMyTrait twelve "-> 12"`. Note that I cannot use Class-side of a regular class, because of name clashes with system (Class, ClassDescription, ...) selectors. Thanks, Peter

Re: [Pharo-dev] spec ui as morph

by Peter Uhnak

#buildWithSpec returns the SpecModel's Morph, which is what you want. `model spec instance`, which is the same as calling `model widget` returns the model's Adapter; but don't use the former, I will remove it in Pharo 7. If you want retrieve the morph from Spec after it was built, then yourModel widget "-> Adapter" yourModel widget widget "-> Morph" Peter On Wed, Apr 26, 2017 at 12:23:03PM +0200, Nicolai Hess wrote: > 2017-04-26 12:00 GMT+02:00 Christophe Demarey <christophe.demarey(a)inria.fr>: > > > thanks but the result is not a morph. > > > > Are you sure ? > > (TextModel new text: Morph comment; buildWithSpec) openInHand -> a Morph > > > > Should I use yourModel buildWithSpec spec instance? > > > > > Le 26 avr. 2017 Ã 11:55, Esteban Lorenzano <estebanlm(a)gmail.com> a > > Ã©crit : > > > > > > yourModel buildWithSpec. > > > > > > Esteban > > > > > >> On 26 Apr 2017, at 11:51, Christophe Demarey < > > christophe.demarey(a)inria.fr> wrote: > > >> > > >> Hi, > > >> > > >> Does anyone know how to embed a UI component made with Spec into a UI > > expecting a morph? > > >> It looks like the only way to build a spec UI is to open it with > > #openWithSpec that will always embed the component in a window. > > >> > > >> Thanks, > > >> Christophe > > > > > > > > >

thanks but the result is not a morph.
