When I shift click a Workspace window the item selected is usually a PluggableTextMorph or a TextMorphForEditView. When it is a PluggableTextMorph it owns a TextMorphforEditView which was not picked by the click. Inspecting or exploring the hierarchy shows that is owned by a SystemWindow of a Model Workspace further up the hierachy. What code do I need to first list all TextMorphforEditView(s) in the system and lookup the ownership hierarchy to determine whether the model of the SystemWindow is a Workspace or a Transcript? > -- >> > Frank Church > > ======================= > http://devblog.brahmancreations.com > -- Frank Church ======================= http://devblog.brahmancreations.com

Is there a way of listing all the DoIts which have been done in a session as well as which workspaces they were done in?

Is there a bug in the way previous Workspace contents are retrieved?

by Frank Church

When I click on the small arrow in the corner of a workspace to get the previous contents, I am unable to get back the present contents. It is as though the contents from a different and probably closed Workspace is what shows up on the list and the current text in the workspace is lost forever. -- Frank Church ======================= http://devblog.brahmancreations.com

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.
