BlockClosure>>isClean bug?

by Johan Fabry

Hi all, I was wondering if there is a bug in BlockClosure>>isClean. As I understand it (see method comment below), the code below should evaluate to false as it closes over foo, but it does not. Here is the comment for isClean: "Answer if the receiver does not close-over any variables other than globals, and does not ^-return (does not close over the home context). Clean blocks are amenable to being created at compile-time." | foo| foo := Time now. [foo] isClean ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile

It wouldn't open in a text editor . I am interested in something which persists in Smalltalk, so I can just browse them without saving to disk, 'The Smalltalk Way'. Saving to disk is an option though. Is there a way of selecting a workspace and extracting the text it contains. Something like a small script to enumerate all open Workspaces and printing out their text contents in a Transcript? I saw your blog article about using Smalltalk to view the contents of your mailbox and the other about parsing a feeds contents and I want to try something similar as a start. My thoughts are along these lines. 1. Define a class consisting of workspace and a method which returns their text content. 2. Define collection 3. List workspaces and add to collection. I am not sure if this will replicate the workspaces perhaps they should be 'pointers' to the workspaces 4. inspect/explore the results like you did in your blog.

I usually just start with an OrderedCollection until I feel the need for something more complicated. It's like an Array, but will grow dynamically. Two things to check out that already exist in the system: * you can save workspace contents to a file by clicking the little arrow in the top right of the workspace window and select "Save As..." * check out ScriptManager, which is a GUI for organizing and saving workspaces. It was included in Pharo by default in 1.3 (I think) and has a repo on sqs... search the list to see how/if it can be loaded into later Pharos.

Furthermore, the class definition itself is not a real method. It actually recreates the definition from the class itself. You can evaluate, Class definition to get the string back :). hope that answered your question :)

How do I save contents of Workspace into a collection?

by Frank Church

Hi guys, My images are gathering a number of Workspaces whose contents I don't want to delete. I want to create a collection of Workspace contents along this defintion: Description Date Category Content (the actual text in the Workspace). In the final version I would like to be able to select a workspace and simply click a button or a menu item and get a dialog where I can enter the Description, Category and Date with the Workspace contents automatically captured into a text box. Copying and pasting the contents would be okay to start with. Filing it out would be another aspect later. What kind of array would best suited to the task? There is quite a number of them depicted here: http://www.jmcsweeney.co.uk/computing/m206/collections_intro.php What could be the best way to go about it? For those who are curious I am experimenting with the original ideas of Smalltalk where a computer user would do everything in Smalltalk workspace/desktop. I am intrigued by the possibility and somehow it seems eminently doable. -- Frank Church ======================= http://devblog.brahmancreations.com

[PharoCasts] Athens + NativeBoost how to

by Baveco, Hans

Hi, I tried to get Athens working (windows) following the instructions in http://www.pharocasts.com/2012/06/athens-and-native-boost-at-work.html Wasn't successful, maybe because things have changed in the meantime? (for instance, couldn't find a TCairoLibrary class, etc). Tried with both 1.4 and 2.0 beta, both with the latest NBCog vm, and with Athens 1.1 and 1.2.... Are there any updated instructions available somewhere, to get Cairo/Athens working? (I am in the first place interested in Cairo) TIA Hans
