[ANN] Animation package
by Thibault Raffaillac Nov. 23, 2016

Nov. 23, 2016

Hello, I am happy to release the Animation package at last! http://smalltalkhub.com/#!/~ThibaultRaffaillac/Animation This is a general animation system, which can turn any setter message into a smooth transition (provided the target value supports + and *Float). Examples: AnimationProperty new at: morph set: #position: to: 100@100 during: 2 seconds easing: #backOut. AnimationProperty new at: morph set: #color: to: Color red during: 2 seconds easing: #linear. AnimationProperty new at: morph set: #title: to: 'tutututu' during: 2 seconds easing: #linear. Or equivalently (don't choke): morph position: (100@100 during: 2 seconds easing: #backOut). morph color: (Color red during: 2 seconds). morph title: ('tutututu' during: 2 seconds). It basically sends the setter message repeatedly during the target delay, each time with a slightly different value. It should also work with Bloc, although the update mechanism depends on Morphic's deferredUIMessage at the moment. Cheers, Thibault ps: Thanks to anonymous contributor for the second syntax, it was a lot of fun - and evil laughs :)

Re: [Pharo-users] Rest Services with pharo objects as parameters
by Esteban Lorenzano Nov. 22, 2016

Hi, if this is from voyage, then is a complicated query, because it is storing a reference to a second root. Letâs say you have an object a1 who is an instance of A and an object b1 who is an instance of B. b := B new. a := A new data1: 42; data2: âsomethingâ; refB: b. which means what you want, in plain Pharo would be something like this: aCollectionOfA select: [ :each | each refB = b ]. but since you want to use Voyage, I guess you want to execute the query *in mongo* (to avoid loading all instances of A into memory). So, in voyage you need to do it in some hack way: B selectOne: [ :each | â¦ ]. A selectMany: [ :each | (each at: ârefB.__idâ) = b voyageId ]. this will solve your problem, I guess. Esteban ps: this is hacky because what in general you do with this kind of structures is to keep a list of A in B, along with your list of B in A (that means, you define a many-to-many relationship) > On 22 Nov 2016, at 11:42, Asbath Sama biyalou via Pharo-users <pharo-users(a)lists.pharo.org> wrote: > > > From: Asbath Sama biyalou <asamabiyalou(a)yahoo.com> > Subject: Rest Services with pharo objects as parameters > Date: 22 November 2016 at 11:42:25 GMT+1 > To: Pharo users users <pharo-users(a)lists.pharo.org> > > > Hello Everybody. > > I have two classes ClassA(data1 data2 ref_ClassB) ClassB (data3 data4). > > I want to get list of classA where ref_ClassB = ClassB.

Does anyone know what the state of PharoJS is? I am looking at working on a big node.js project and would like to see if I could use PharoJS to do a lot of the work. ----- Brad Selfridge -- View this message in context: http://forum.world.st/PharoJS-tp4924045.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

FUEL not working
by HernÃ¡n Morales Durand Nov. 21, 2016

Nov. 21, 2016

Hi guys, Maybe I am doing something terribly stupid but FUEL is not correctly serializing a Set. I uploaded a video so you can check: https://youtu.be/wAQgbkqAXtk As you can see, there is 1 new object in the Set, on serialization the file grows, but on materialization the new object is not present. Any hint? Using Pharo 5 here. Cheers, HernÃ¡n

Such types are handle_t / HANDLE TCHAR LPCTSTR PVOID also I will have to deal with Unicode , I have no clue how to proceed, any help is greatly appreciated.

Improving comments cool action
by stepharo Nov. 20, 2016

Nov. 20, 2016

Hi guys I would like to see how we could build a concerted action to improve the class and method comments in Pharo. Now we have package comments :) so we should take also advantage of them. I would love that a newbie is highlithed by class comments. So I would like to start to comment key core classes. I'm sure that if we all spend 30 min per week we can really have a huge impact. I was planning to start with collection classes. Now let me know if you want to help. Stef
