re: About Flow in Squeak 3.X
by Craig Latta 02 Dec '03

02 Dec '03

(This seemed sufficiently different from the original thread subject, "FileList[2]>directory: oddity", that I thought I'd start a new thread. Squat mailing list info is at http://netjam.org/squat . Squat is a minimal-snapshot-and-virtual-machine project.) Hi Stef-- > do you have a plan to get a smooth integration of Flow (meaning > slowly deprecate the current stream)?

However it would be good to > start to thing how flow could become a good replacement of Stream. > > What are your current plans? I'm not expert in Streams so does > anybody expertise on Flow and stream comment? As I've mentioned before on the Squeak list (but not on a webpage, sorry, will get to that), I'm focusing my attention on Flow releases for Squeak 4 and beyond, when ostensibly there will be a minimal snapshot to work from. It's just so much nicer than dealing with the traditional accreted snapshot and the release process constaints it imposes. And I don't just feel that way in the context of Flow; I want to release *everything* I do as modules for a minimal snapshot. After that infrastructure is in place and Flow is available through it, then I might make releases for older systems. It's not all that hard; I had to do it for 2.2 to get the Squat work started, after all. :) It just takes time, and the minimal snapshot work is much more important to me right now. So that's timing (although we don't have dates for things yet). As for the technical execution, I think it'd be straightforward. I've been careful in each Flow release so far to make sure that the old and new stuff work together in the same system, although some *clients* may need to be updated, when there is class name contention. The most recent release of Flow, 2 alpha, does this for Squeak 3.2, the version that was current at the time (August 2002). Class name contention was the main issue with that release (the old Stream became "OldStream", etc.). Not really a big deal, in my opinion, and of course handled a lot more easily in a modularized system (where one can refer to classes by ID and not name, for example, and have multiple versions also). I've found in the past that if you let the old things keep the old names, people stay complacent, even if you run reports that point out who hasn't converted yet. :) Finally, the Flow 2a release has everything separated out pretty well into different changesets; in particular, all the forward-compatibility stuff is easy to find. Another thing that makes me confident is that I've already converted a Squeak system from old streams to new (at a past employer). I actually removed all the old stuff, and things were fine. thanks, -C -- Craig Latta http://netjam.org/resume craig(a)netjam.org [|] Proceed for Truth!

[ENH] TestRunnerEnh-nk
by marcus＠ira.uka.de 02 Dec '03

02 Dec '03

from preamble: "Change Set: TestRunnerEnh-nk Date: 6 August 2003 Author: Ned Konz 6 August 03 (1.9): 3.6 compatibility. Made into a Model subclass. Made debugger step to beginning of failed test case. Added window colors. Added to flaps registry. Fixed browsing. 1 May '03 (1.8): Fixed behavior of progress morph when collapsed and re-expanded. 23 Dec (1.7): Fixed for compatibility with TestBrowser. 19 Dec: Added fixes for abstract classes from Magistrello Alejandro. 19 Dec: Added to World menu. Made top divider work right. Added button spacing. Made it respect window color choice. Kept select/deselect all from scrolling list. 15 Dec: kept it from scrolling back to the beginning when you deselect a test. I didn't like the TestRunner tying up the UI. So this version runs tests in the background; I'm going to post a TestCase subclass for UI testing soon. Also: * adds progress notification * adds a stop button * You can select which tests you want to run. * It sorts the test cases by name. * It works in a MVC project. * It has a context menu for the selection list * It allows you to select test cases by pattern This includes changes by Stephan Wessels: The most obvious changes will be related to the buttons having fixed widths, and the small text panes having fixed heights regardless of resizing. The buttons use rounded corners and all the panes use window existing preference settings for border shape and colors. If the optional buttons preference is turned on, the tests list pane includes the main menu items as optional buttons. "!

[ENH] ParenBlinking ( [et] reposted as changeset )
by marcus＠ira.uka.de 02 Dec '03

02 Dec '03

from preamble: "Change Set: ParenBlinking Date: 8 October 2003 Author: Avi Bryant md: reposted as real changeset. Avi writes: This has been on SqueakMap forever, but I figured with the new BFAV and so on it might be worth posting it as an ENH, in the hopes that it'll actually make it into the image. This makes two changes to the ParagraphEditor: 1. upon typing ), }, or ], the matching (, {, or [ will be made bold until the next keystroke 2. the meanings of return and control-return are switched (ie, auto-indent is the default) I have had this changeset loaded in every image I've used for the last year and a half, with no ill effects. I think it makes the ParagraphEditor significantly more useful for writing code (which is, after all, what most of us use ParapraphEditor for most of the time). If people want change 1 without change 2, I'm happy to introduce a preference that controls that (although I personally think of auto-indent as something any good text editor does, and can think why you wouldn't want it). Separating them into two changesets is more difficult, however, since they both need to modify #dispatchOnCharacter:with:. Cheers, Avi "!

SM2 Testing
by Thomas A Petersen 02 Dec '03

02 Dec '03

Goran, [Snip] > And I assume you actually got the new package > loader (the one with the tree view with releases > below the packages). Just checking. :) Yes, it is the "new" browser. I like it! Apply the nice hierarchy list enhancement to add the lines and set the font to something less microscopic and it looks and feels seriously cool. Sigh, I tried to load NetModel and it gave my a 'Key not found' alert with an OK button. Dismissing it leaves Dave's progress morph whizing along untill you use the pink morph halo to get rid of it. So far, that's all I've found. Thanks again, tap

SM2 Testing (was [BUG] SM2 Burps after loading Breakpoint support or ColorDevTools)
by Thomas A Petersen 02 Dec '03

02 Dec '03

Goran, [snip...] > Stop right there. :) ... [snip...] > 7. SqueakMap2 - A load script which will update your 3.6/3.7 image to SqueakMap2. [snip...] Based on your guidance, here's what I did: 1. Start Squeak 37a 5566 image fresh out of the zip file. 2. Iconofy the welcome window by clicking the upper right corner 3. World menu | open | Package Loader 4. Select 'SqueakMap2 (->0.9)' 5. Right Click | Install Lots of progress bars and trundling. Very good.... Received alert 'Error occured durring install: AnObsoleteSMCard>>notInstalled' coicked OK There appears to be a new package loadere here. 6. SqueakMap2 appears to still be selected. Scrolling quickly shows that it is just a screen artifact. 7. Select 'Breakpoint Support (->1.25)' 8. right click | Install Things appear to be happy. 9. Select 'ColorDevTools (CDT) (->0.1a)' right click | Install More trundling... get Readme.CDT. Dismiss it with X button. 10. Select 'Connectors (->0.9)' 11. right click | install More trundling... get README and CHANGES. dismiss both with X button. The Connectors, FSM, and Class Diagrams flaps have appeared. The 'New Connectors Drawing' project has appeared. 12. Select 'Jacaranda (->12-apr-2003)' right click | install More trundling... Get README and CHANGES windows. dismiss with X button. The Jacaranda flap has appeared. 13. Use tools flap to get a change sorter. Note that all of the change sets have been loaded. 14. Dismiss the SM2 browser with the X button. 15. Save the image as: 'Squeak3.7a-5566-SM2.image' as a base for further tinkering. The operation appears to be a complete success. Thanks for the guidance. I know that this is just a beginning. Hopefully, I can find time to try out more of the features beyond just simple package loading. Thanks for letting me help, tap

02 Dec '03

from preamble: "Change Set: yaxoRemoval-mir Date: 22 July 2003 Author: Michael Rueger md: this is from SqueakMap. We have currently a pretty old Yaxo version in the image, and actually it's not used by anything in the image. Added a postscript for removing the categories. Removes Yaxo, the XML parser from the image."!

SM2 beta testing still needed...
by goran.krampe＠bluefish.se 02 Dec '03

02 Dec '03

Hi all! Well, in order to get SM2 up for real I still need some reports about the beta that is up. Please people, you need to help me here because I don't want to deploy it and then get heaps of complaints about bugs... So go to: http://anakin.bluefish.se/sm And register, or login using your old email (or developer initials if you have them entered on minnow) + one of your old package passwords (test them all). Or let it send you an extra password. Mess around the web UI (test as much as possible) and try the new Package Loader by installing load script "SqueakMap2" using the old package loader - BEWARE that this should probably be done in a "throw away image". Not sure about later removing SM2 and getting SM1 back - haven't bothered looking into that. regards, Göran PS. Only interested in bug reports right now - I know there are tons of cool stuff to add, but let us take those later. PSS. Yes, the web UI is crummy in many parts - but I don't care at this point.
