Yesterday I tried again to use Versionner in 2.0 but did have much success. So I tried myself (because I think Versionner is important) and could final generate a new version of my project using versionner. Following things I noticed (I'm writing this because I'm not sure which issue to open for what package. I'm just want opinions and after that I can open/upload whatever): I loaded Versionner from Metacello (taken from [1]) Gofer new url: 'http://ss3.gemstone.com/ss/Versionner'; package: 'ConfigurationOfVersionner'; load. (Smalltalk at: #ConfigurationOfVersionner) perform: #load monticello issues ============= While updating the rest of the packages to the newest I saw that Versionner-Core-Model-ChristopheDemarey.19 has an older ancestor for fixing something for pharo 1.4. The package Versionner-Core-Model-ChristopheDemarey.20 merged the packages back to HEAD but reverted some things like SystemAnnouncer back to SystemChangeNotifier. So I'm using Versionner-Core-Model-ChristopheDemarey.18 and Versionner-Core-Commands-ChristopheDemarey.17 as older packages. Any other package is the newest in the repository. metacello toolbox issues ================== I don't know much about metacello toolbox but the separation of files into ConfigurationOf and Baseline seems to have potential for confusion. There is a notion of a basename so it can build ConfigurationOfMyProject as well as BaselineOfMyProject (MyProject being the basename). But in the MetacelloToolbox in the pharo2.0 repository it does not seem right. I had to change the code to use (MBToolbox baseNameOf: â¦) at a few places. I took orientation from the message signature. If a method expects a configurationBaseName and the sender used the configuration class I changed it. I'll attach the mcz for now to this mail until it is clear what to do. versionner issues ============= At one place I added a metacello toolbox name conversion because it made sense to make it there. The other thing I had to fix is a method notification that takes the wrong entity from an announcement. Both packages attached as I don't have commit rights and don't know where the issue tracker for versionner is if there is any) I would be glad if any of you guys that know about that stuff could drop me a note if this is ok or where I've gone wrong. thanks, Norbert [1] http://users.dcc.uchile.cl/~jsandova/versionner/
