Yes, it does but the file is present and normally in the right version.

I installed it using the package manager.

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.

A generator for the visitor design pattern:
- Generate methods in visited objects: VisitedObject>>#accept: (with the

- Generate empty methods (or methods with a "self

called in #accept: methods of VisitedObjects in the Visitor i.e

[Pharo-users] State of Pharo in comparison with the "Pharo vision" document

2016-07-19 Thread Julien Delplanque


Hello everyone,

For a university project I need to write a little about Pharo.
I found the "Pharo vision" document [1] and I am curious about
the actual state of Pharo in comparison with it.

I have seen some things on the mailing list but I would like some
help to gather the state of each goal described in "Pharo vision"
version 1.0.

I made a list with the goals and wrote some of the (little) knowledge I
have about some elements (I also joined it to this mail in case it is not
readable):

Goals -> State
---
1.  Creation of the Pharo Consortium -> Created
2.  Small kernel & validated packages -> ?
3.  A Robust and Extensible System Events -> ?
4.  Rewrite of Filesystem/Streams -> ?/XStream?
5.  Announcements and Ephemerons -> ?
6.  UI Canvas for Zoomable Interfaces -> Bloc?
7.  Bootstrap of the Core -> ?
8.  Fully parametrized compiler tool chain -> ?
9.  Packages as real objects -> ?
10. Package Meta-Data -> PackageManifest?
11. Less Model Clutter and Duplication -> ?
12. Building and Reusing UI Logic -> Spec?
13. New Network Layer -> ?
14. Serializers -> Fuel
15. SystemChangeNotifier replacement -> ?
16. Cleaning Morphic -> Still valid? (asking because of Bloc existance)
17. Everybody should be able to compile VMs -> ?
18. VMs identification and regression testing -> ?
19. One Unified FFI framework -> Created and still being enhanced
20. 64 Bits -> I saw the screenshot on Twitter but what is the state now?
21. New Object Formats -> ?

If some of you know the state of one or many of these project and have the
time to give me some information about it/them, I would be really grateful.

Thanks in advance,

Julien

Re: [Pharo-users] [UFFI] Getting an array of opaque structures filled

2016-07-04 Thread Julien Delplanque


Ok, the problem is resolved thanks to Esteban.

There was a mistake in the code given in preceding mails so, I am 
rewriting the 3 steps here:


===

1) Declare your class that subclasses FFIOpaqueObject:


FFIOpaqueObject subclass: USBDevice
etc...

2) Get a pointer to the array:

arrayPtr := ExternalAddress new.
size := self getDevice: context list: arrayPtr.

with:

getDevice: ctx list: list
^ self ffiCall: #(size_t libusb_get_device_list (libusb_context 
*ctx, void **list))


3) Now that we have the size of the array, we can declare it:

array := FFIExternalArray fromHandle: arrayPtr type: USBDevice size: size.

===

The problem was that I was using #fromPointer:type:size instead of 
#fromHandle:type:size:.


Thanks again Esteban!

hi,

this is because you want to get an array with opaque objects. Do not let the 
*** confuses you… cwhat you actually want, conceptually is something like this:

*((FFIOpaqueObject*)[])

means: you pass the address of an array of opaque types (who are always 
pointers).

So, what you need to pass is the address of an array… you will need to work a 
bit here, since translation is not automatic.

1) you need to declare your type. Let’ say it will be:

FFIOpaqueObject subclass: USBDevice.

2) then you need to get the pointer to this array. You need to rewrite you code 
as this:

arrayPtr := ExternalAddress new.
size := self getDevice: ctx list: arrayPtr.

getDevice: ctx list: list
^ self ffiCall: #(size_t libusb_get_device_list (libusb_context *ctx, 
void **list))

NOTE that we change the type to "void **”. This is because this is what you 
actually want: the array of devices

3) now you will have size and arrayPtr. Then you declare the array:

array := FFIExternalArray fromPointer: arrayPtr type: USBDevice

sorry, this expression (while possible) does not stops in “size”… it has to be 
like this, instead:

array := FFIExternalArray fromPointer: arrayPtr type: USBDevice size: size. “you 
already has the size for the result"


… and you should be able to iterate this array normally :)

let me know if this works for you… I’m “coding in mail client”, so it can fail 
:P

1) you need to declare your type. Let’ say it will be:

sorry, this expression (while possible) does not stops in “size”… it has to be

2016-06-30 Thread Julien Delplanque


Hi,

Ok then I need to think about a nice solution...

Maybe by making the shortcut modifiable by the user in the "Settings 
browser"?


I think it would be good to have Ctrl/Cmd+Tab on all platform but it can 
be done yet.

Argh i was so thrilled by this ! But it doesn't seem to work on windows :/

Ctrl+tab gives the focus to the front window or makes an "inspect it" on
the current editor line...


For windows, to make ctrl+tab working, you need to disable the
"hasSpecialCTRLKeyValue"-check (I think this check is not needed anymore,
since we changed the
windows vm for ctrl+number/tab/space... keystrokes)



Thank you anyway !

Objet : [UFFI] Call a function where argument type is char ** (argv)

Hello,

I have written a R bridge in Pharo and I would like to migrate it from
NativeBoost to UFFI.
Most of the changes are easy to do but I am stuck to a double pointer problem.
I have to call the function: int Rf_initEmbeddedR(int argc, char ** argv). I
know how to give the int but the char ** is a problem. It is an array of
Strings.

With NB, I managed to have this (working) code:
"This is 32bit... too bad..."
strings := OrderedCollection new.
par := NativeBoost allocate: 4 * params size.
params
keysAndValuesDo: [ :i :each |
| str |
str := each asNBExternalString.
strings add: str.
par nbUInt32AtOffset: (i - 1)
* 4 put: str value ].
self prim_initEmbeddedRargc: params size argv: par ]
ensure: [
"Free the memory we allocated"
par ifNotNil: [ par free ].
strings ifNotNil: [ strings
do: [ :each | each free ] ] ]

With a primitive call:
Self nbCall: #(int Rf_initEmbeddedR(int argc, char *argv))

Do I still need to create my own array of strings or FFI creates it for me? How?

Thanks in advance for your answers,

Vincent

Is it ok, in the design point of view, to use them to force an object to

Why not using a parent abstract class for that, with required method

Yes this is what I do for now. But what if I do not want to force the 
use of inheritance?


Then from your tests in subclasses, you check

self shouldnt: [instance toto] raise: SubclassResponsabilty


This wont work if the object does not implement #toto at all.

Like that it would be possible to check (via an #assert: for example) if
a class provides the interface required.

I read some things I found on the net about Traits and already used
TComparable but I never created one myself and I am not sure to
understand this concept entirely.


With Trait you add behavior to a class. TComparable adds behavior to
your class, your instance are then comparable.
Is it a problem? Isn't it similar to Java's interface? I see traits as a 
mix between Java's abstract classes and Java's interface
since you can define methods and let some of them abstract but you can 
not define instance variables.

But maybe I am wrong, that is why I ask :)...

[Pharo-users] Strange behavior of Pragma>>#allNamed:in:

Hi,

I experience a strange behavior with Pragma>>#allNamed:in:

When I use

Pragma allNamed: #myPragma in: MyClass

It works as expected.

But when instead of hard-coding "MyClass" I use "self class" in an 
method (instance side),


Pragma allNamed: #myPragma in: self class

returns an empty array.

What can I do about it?

How do spec manage nested focus order? I see in the implementation

Hi Julien,
how are WidgetA and WidgetB connected ? Are they both (spec)-models

Hi Nicolai,

Yes they are subclasses of ComposableModel used by another main model.

Ok, so, if your main model has instance  variables for widgetA and 
widgetB,
can you add this in the method where you instantiate WidgetA and 
WidgetB:


widgetA focusOrder add: widgetB.
widgetB focusOrder add: widgetA.

Oh ok, I will try that. I was adding widgetA and widgetB to the 
focusOrder of my main widget :/...


Thanks,

Julien

When I use your method, I have the good behavior when going to the next 
sub-widget using tabulation but I have a strange behavior when going to 
the previous widget.


If I take the same example with widgetA and widgetB, when trying to 
reach previous sub-widgets with the focus, I can only access the first 
button of each sub-widget is it normal? How can I fix this?


Thanks in advance,

Julien

Hi Steph, Julien,

Iooked at the fix for this issue.
Implementing #activate on WindowModel and delegate to
self window
of course works.
But I am unsure if we want to do it that way, because messages like
#maximize #minimize are implemented differently.

I don't know what is the  preferred way for models to communicate with
widgets through the adapter. But if we
follow  the way of maximize and minimize, an implementation for
WindowModel>>#activate
could be

 self changed: #activate with: #()

and this needs another change in MorphicWindowAdapter>>#activate

 self widgetDo: [ :w | w activate ]


what do you think?

I understand what you say but sadly, it will not work in my case because:

Hi,

You can create a class programatically using:

instanceVariableNames: 'instVar1 instVar2'
classVariableNames: ''

Then you can add method using:

ClassName compile: 'helloWorld

for example.

"myWidget window window" gives a SpecWindow which inherits from 
StandardWindow, a morph.


Thanks a lot for the help!

Is it possible to put a WindowModel on top of all other windows opened?
If it is, how?

I'm not sure where you are looking for, but did you look at the WorldModel?

How, a little precision, when I say "Is it possible to put a WindowModel on top of 
all other windows opened?" I mean programatically of course :p.

There is

  openWorldWithSpec

as used in PharoLauncher.

Are you looking for a (modal) dialog or building a custom application 
with no pharo IDE? Spec does not have fine-grained control over layers,

for that you need the Morphic level, where you can say e.g.

setProperty: #morphicLayerNumber toValue: 18.

to be on top of normal windows.

I am building a custom application. Ok, so I need to work at Morph level.
To retrieve the morph associated with the WindowModel, do I need to use 
World submorphs and detect it or is there another way?


If I retrieve the SpecWindow, I can simply send #activate to put the 
window to the top...
