[UFFI] Using a nested structure
by Merwan Ouddane July 11, 2016

July 11, 2016

Hi, I have an issue whith nested structures. I made some "dummy" structures in c: typedef struct vec3 { double data[3]; } vec3; typedef struct position { int i; vec3 vec; } position; And a "dummy" function to fill it: void fillStruct(position *position) { position -> i = 19; (position -> vec).data[0] = 1; (position -> vec).data[1] = 2; (position -> vec).data[2] = 3; } But I can't make the nested structure work. The "i" is correctly set to 19 but I have values that doesn't make any sense in the vec3 structure. In Pharo I declared the Double3 type for the array inside Vec3: Double3 := FFITypeArray ofType: 'double' size: 3 Vec3>>fieldsDesc ^ #( Double3 v; ) And the position: Position>>fieldsDesc ^ #( int i; Vec3 vec; ) The ffi call: ^ self ffiCall: #(void fillStruct(Position *position)) module: 'Test.dll' Sorry for the long / messy mail :p Any clues ? Cheers, Merwan

Failing to create a project on SmalltalkHub
by Victor RENE July 10, 2016

July 10, 2016

http://smalltalkhub.com/#!/~VictorRene I am trying to create a project on Smalltalk hub to save progress on the MOOC. But it fails with "incorrect username or password", and i can not logout. Okay, I can probably empty my browser cache but it's still incorrect behavior. Also, they say it's possible to use Git but they don't describe the setup. Any ideas? Thanks in advance.

Is there a clean way how to close or not open the Pharo 5.0 welcome window? Short of going through the stack and closing it (courtesy of Cyril) (SystemWindow allInstances select: [ :w | w labelString includesSubstring: 'Welcome' ]) do: #delete Thanks, Peter

by stepharo July 9, 2016

July 9, 2016

Hi Johan Fabry is writing a great tutorial (and this is cool to see all the material I gathered or wrote with him in the past) to take such great form. I attached the first chapter. I will post the chapter one by one once I review them (so far I have nothing to do - great feeling). Well done Johan! Stef

Re: [Pharo-users] Spec vs Brick vs Glamour vs Morphic vs WTF?

You can find it on smalltalkhub StephanEggermont/SpecGenerator. In Pharo4 you'll miss spec updates, you'll need to add at least the FastTable based list and the SelectEntity widget. Code generation is straightforward, and should be refactored Stephan Verstuurd vanaf mijn iPhone

How do I debug: "There was an error while trying to install GitFileTree. Installation was cancelled." from Catalog Browser
by Dale Henrichs July 8, 2016

July 8, 2016

Using a freshly downloaded Pharo5.0 and the Catalog Browser, I'm getting a Notification with the message in the subject line while installing GitFileTree, but I get a notification with no indication of why or what the error is ... how am I supposed to debug this? I mean I can guess what load expression is being used, but for a beginner, this is not a pleasant introduction ... There is no Pharo debug log either, so I will have to splash around and try to load GitFileTree, in the meantime... Dale

Recovering PNG/JPG images that were automatically serialized as FUEL when storing into external database
by Offray Vladimir Luna CÃ¡rdenas July 6, 2016

July 6, 2016

Hi, I was storing Pharo objects into an external SQLite3 database. It went fine, but now all my png/jpg images are serialized with FUEL, when I try to see them inside SQLite and when I import them back to the image, they're long byte streams. There is any way to recover the images as png/jpg morphs that visible inside the image again? How can I disable this automatic serialization for making the database portable without using FUEL to recover back the PNG/JPG images? Thanks, Offray
