Thanks for all the replies - this is great! >> Got it. In Squeak, this was the mechanism I used to keep objects from different domains separate, > it did not. I meant conceptually and visually - the metaphor (seemed to me) of stepping into another room in a house filled with objects, so I could put all my financial stuff "in my home office" and my reference books "in the study." >> Is there a similar (or better) mechanism for this in Pharo? > Classes? <snip> > I think that you misunderstand projects and also the purpose of classes and instances. > May be you should read some of the books available on my web page like the art of object-oriented programming. Please understand that I am grateful beyond words that people I don't know ( yet :) ) have created, and are maintaining and improving software and reference materials that are transforming my understanding of what's possible with computers. And... I'm good with OOP (and I read every book about OOP and Smalltalk I could get my hands on, including a few of yours, and enjoyed them all). What I'm not grokking is: my understanding of Squeak (which I applied to Pharo) from all of Alan Kay's work is that it's moving closer toward an "application-less" virtual world, where all objects can communicate with all others - instead of Microsoft Money holding my financial data hostage in a proprietary data file, and Apple holding my notes in Mail.app data files, *I* hold all these objects (and the system itself), all written in Smalltalk, so I have complete control over my computer world. Now... what I am curious about (and haven't found a book to address), is what (if any) are the strategies one uses to conceptually make sense of a virtual world of possibly thousands of (normally, mostly) unrelated objects. For example, 9 out of 10 times, I probably don't care that I have journal entries alive in my image when I'm processing receipts, but the one time I want to cross-reference the journal for keywords for certain purchases, I want access to them. And all I've seen in reference books is how to develop "an application" in Squeak/Pharo i.e. code that does one conceptual thing e.g. moves a turtle, rolls a die, creates a laser game - which were all totally great, and also did not give me any insight to this particular question. Maybe it's something really obvious to a long-time Smalltalker that no one's bothered to write down?! Thanks again. Sean

A problem about SCouchDB library
by zekUs April 6, 2010

April 6, 2010

Hi, this is not a directly pharo specific question but i guess here is the right place to ask. i am playing with scouchdb library. i have a problem. i am trying to evaluate the code below: | dbAdaptor | dbAdaptor := SCouchDBAdaptor new host: '10.24.5.38' port: 5984. dbAdaptor databases. and there is an exception raised: "JSSyntaxError: Missing Comma". it looks like a problem with JSON package but when i debug and inspect the response object in SCouchDBAdaptor>>databases method, i can see the content of the response is nil. but the data i need is in the inBuffer field under cstream of the response. below snippet is the data from response objects' cstream. the data in inBuffer field: 'HTTP/1.1 200 OK Server: CouchDB/0.10.0 (Erlang OTP/R13B) Date: Tue, 06 Apr 2010 13:43:39 GMT Content-Type: application/json Content-Length: 21 Cache-Control: must-revalidate ["baseball","hasan"] am i doing something wrong? best regards. -- zekUs - http://zekzekus.com/blog

Re: [Pharo-users] Projects

> Pharo does not support Projects. Got it. In Squeak, this was the mechanism I used to keep objects from different domains separate, but the amazing Smalltalk beauty of it was that the objects could talk and act across the boundary. I was building a utopian digital world without the artificial boundaries of "applications." Is there a similar (or better) mechanism for this in Pharo? For example: If I was using an image for all my personal computing, and I wanted to manage both my personal accounting and my journal; in Squeak, I would create a MyMoney project and a MyJournal project. How would you handle this goal in Pharo? My objective is to have every domain object in my life be able to communicate with every other object, without having one huge, unmanageable pile. Maybe keep the objects in repositories stored in class instance variables in top-level project-like objects? Like have a MyMoney class contain all the money-related objects, and a MyJournal class keep all the journal stuff... Is any of this making sense? Thanks! Sean

Projects/Project Windows
by DeNigris Sean April 6, 2010

April 6, 2010

How do you create Projects in Pharo? In Squeak, you can select "new morphic project" from the world menu. I found out how to do the same thing programmatically: > Project newMorphicOn: nil. The SystemWindow appears - great, no problem; except... I can't figure out how to enter the project. When I click on it (which would enter it in Squeak), nothing happens. I tried a bunch of other stuff, but couldn't make it happen. Thanks! Sean p.s. more generally, is there a way to get removed Squeak world menu options through the GUI? Or do you have to perform the actions programmatically?

That will let you create "folders" where you can group workspaces. You can put names to both of them, and import and export them to files. If you have opened workspaces, it can also recognise it and automatically create them.

Hi, I am a newbie and this is my first Smalltalk learning effort. I have downloaded Pharo-1.0-10508-rc2 and it is working fine so far. I just want the system to display all the Shared Tabs. So, when I click Configuration -> show shared tabs menu option I get this error: ======================================================================= MessageNotUnderstood: Project>>currentToggleFlapsSuppressed Project(Object)>>doesNotUnderstand: #currentToggleFlapsSuppressed [] in ToggleMenuItemMorph(MenuItemMorph)>>invokeWithEvent: BlockClosure>>ensure: CursorWithMask(Cursor)>>showWhile: ToggleMenuItemMorph(MenuItemMorph)>>invokeWithEvent: ToggleMenuItemMorph(MenuItemMorph)>>mouseUp: ToggleMenuItemMorph(MenuItemMorph)>>handleMouseUp: MouseButtonEvent>>sentTo: ToggleMenuItemMorph(Morph)>>handleEvent: MorphicEventDispatcher>>dispatchDefault:with: MorphicEventDispatcher>>dispatchEvent:with: ToggleMenuItemMorph(Morph)>>processEvent:using: MorphicEventDispatcher>>dispatchDefault:with: MorphicEventDispatcher>>dispatchEvent:with: MenuMorph(Morph)>>processEvent:using: MenuMorph(Morph)>>processEvent: MenuMorph>>handleFocusEvent: [] in HandMorph>>sendFocusEvent:to:clear: [] in PasteUpMorph>>becomeActiveDuring: BlockClosure>>on:do: ======================================================================= How do I get around this issue to have Pharo display the Shared Tabs? Any help is really appreciated. Thanks.

Using FFI on linux 64 bits
by Daniel Galdames G. April 3, 2010

April 3, 2010

Hi, i was trying to use FFI plugin on a 64 bits linux, but when I try the test, or FFI-Examples, the vm crash with a segmentation fault. I was able to use FFI with a i686 vm, calling 32 bits libraries. Is there any way to make a 64 bits vm to call 64 bits libraries? or it isn't supported yet? Thanks. Daniel Galdames G.
