Provided packages from Metacello project configuration

by Panu Suominen

This is probably wrong mailing list for this question... Is there a way to define what categories/packages/classes are provided by the given configuration? For example ConfigurationOfXXX project latestVersion providedPackages This would not include the packages that are required by the project and are actually provided by other configurations/projects. If there is a way to produce this kind of package list it would help implementing CI-testing. Testing script would not have to explicitly list what packages to test but could refer to the project definition. Currently one has to alter the testing script every time the packages are changed. With this kind of information one could implement project CI-builds with something like this: whatToBuild := ConfigurationOfXXX project lastVersion. whatToBuild load. HDTestReport runPackages: whatToBuild providedPackages. HDLintReport runPackages: whatToBuild providedPackages. And then it would be easy to build custom Job plugin to Jenkins that would simply ask about the name and the location of ConfigurationOfXXX. -- Panu

IMHO the only fix is to use the image from the website. There is a reason for this image. If you are a newbie than everything that does not work like it is written in the book is distracting. Giving advize to load a browser that is neither in the book nor is it used by a lot of people is definitely not a good idea. Norbert

I've tried starting it several times, including after a reboot, with the same results. I get a popup entitled "Fatal VM error', with some numeric details. When I click ok, it writes a crash.dmp file and closes. 1) Is there a way to to recover the image, if I start with a clean image? 2) Is there anyone who wants a copy of the crash.dmp report?

StandardWindow is part of Polymorph (so you have all Polymorph helpers defined in TEasilyThemed). You may want to use SystemWindow if you want to distribute a smaller image (Polymorph unloaded) or don't use/like Polymorph.
