[BUG][FIX]AcornFileDirectory fix for 4282 update
by Tim Rowledge 29 Aug '01

29 Aug '01

The latest 3.1 image uses some odd corners of the directory contents to find out if a directory path exists. It exposed a problem in the Acorn VM/low-level stuff that this fixes. It _must_ go in in order to maintain portability. tim -- Tim Rowledge, tim(a)sumeru.stanford.edu, http://sumeru.stanford.edu/tim Strange OpCodes: EBO: Emulate Brown-Out

New Look&Feel suggestions
by Diego Gomez Deck 28 Aug '01

28 Aug '01

Atached are 2 screenshot with my suggestions to the new Look&Feel. I suggest 2 (more) changes: 1) Color the pane with buttons with a dark color from the set of possible colors. 2) For the others panels use (instead of white) a lighter color (very lighter) from the set. TIA, Diego Gomez Deck PS: My 2 cents! :)

VM uploading to the Swiki
by Andres Valloud 28 Aug '01

28 Aug '01

Hi PhiHo. I am having trouble connecting to minnow right now... Netscape keeps waiting for a reply... in the mean time, I made sure that the base tests all pass with this VM. I got 1168 run, 1168 passed, 0 failed, 0 errors. I'll send a message right after I put this VM in minnow. Andres.

Tests do not pass with SWT 0.6
by Andres Valloud 28 Aug '01

28 Aug '01

Hi PhiHo. Looking over the list I realized what's probably going on. My guess is that should:raise: in SUnit is not working properly because exceptions are broken. Therefore you get all the exceptions raised inside should:raise: blocks which should (but don't) handle those exceptions. In this context, those tests failing are most probably basic tests, those that make sure that something like aCollection detect: [:x | x zork] fails, or something like Interval from: 1 to: 5 by 0 fails, etc. Something that is telling about this is that an exception test failed in NiladicBlockContextTestCase. So probably there's a mismatch between the image and the VM. I know exceptions had been changing, but SWT 0.6 is still using the previous exception code. Tell you what: I'll upload the VM I have been using to release SWT 0.6 in the Swiki. If that VM works but yours doesn't, then it's most probably an exception problem. It should be possible to come up with a newExceptionStuffModule that, upon loading it, would make the SWT 0.6 image work with other VMs. That module would be heavily based on Squeak update number 3796.

New Look Suggestion
by Jochen F. Rick 28 Aug '01

28 Aug '01

Hi! I really like the alternate look. It's a great mixture of fun Squeak coloring combined with black text on white background. The only thing that makes me cringe is the scrollbars; they just don't fit in. Here's a simple suggestion of how to make them fit in: Make the borderColor equal the PaneColor darker. Also, the background of the ScrollBar rectangle could be the light window color. I don't really mind the gray though. If you're going to have black text on white background, gray scrollbar is fine by me. Peace and Luck! Je77

RE: [ANN] SWT 0.6 released

>I've had no luck doing anything with these images- what am I missing here? A short intro to the Squeak world tour image: Start the SWTDev0_6.image with the VM. It already contains the repository code so you dont have to use the code in the "Squeak Worldtour Bootstrap" workspace to bootstrap the repository. Seems like this is the only difference to SWTBase0_6.image. The second workspace "SWT code configurations" is able to build so called "Build lists" from a repository URL and file it in. An example: url := (RepositoryUrl fromString: 'repos://SqueakBase/SUnitConfig/0.2'). url resolve build. url := (RepositoryUrl fromString: 'repos://SqueakBase/BaseTests/0.2'). url resolve build will load the SUnit-Configuration and all the basic s-unit tests into the image. Now you are able to open the "S-Unit test runner" in the "open" menu. Use url := (RepositoryUrl fromString: 'repos://SqueakBase/RepositoryConfig/0.3'). url resolve build to get the repository configuration. This allows you to open the repository browser by evaluating "RepositoryBrowser open". This browser allows you to view the contents of the repository as well as the creation of new repositories and entities. If you need the refactoring browser use: url := (RepositoryUrl fromString: 'repos://SqueakBase/RefactorAndLintTestConfig/0.2'). url resolve build After that you are able to open the refactoring browser in the "open menu". You can also file in single repository entities, an example: |pathSpec pathStream path| pathSpec := #('SqueakBase' 'LedMorphs' '0.2'). pathStream := WriteStream on: String new. pathStream nextPutAll: FileDirectory default pathName; nextPut: FileDirectory pathNameDelimiter. pathSpec do: [:eachPathElement | pathStream nextPutAll: eachPathElement. pathStream nextPut: FileDirectory pathNameDelimiter ]. path := pathStream reset; next: (pathStream size - 1). FileStream fileIn: path This will load class LedMorph into your image. Keep on talking small Torsten Bye Torsten
